Objective:To compare the mechanical properties between our self-designed axially controlled compression spinal rod (ACCSR) and conventional spinal rod (CSR) for lumbar spondylolysis (LS).Methods:This study selected 36 ACCSRs (the ACCSR group) and 36 CSRs (the CSR group), both of which were in a diameter of 6.0 mm and manufactured in the same batch. They were subjected respectively to biomechanical tests of spinal rod and pedicle screw-rod internal fixation system. In spinal rod tests: the stiffness and yield load of the spinal rods were calculated using four-point bending tests ( n=7) and comparisons were made between the 2 groups; spinal rod fatigue tests ( n=8) recorded the successful compression loads after 2.5 million cycles of loading and compared them with the maximum force at the isthmus of a normal adult's unilateral lumbar spine (198.72 N). In tests of the pedicle screw-rod internal fixation system, the axial compression tests ( n=7) measured the axial gripping capacity, the axial torsion tests ( n=7) the torsional gripping capacity, and the lateral compression tests ( n=7) the stiffness and yield load of pedicle screws in the 2 groups respectively. Results:The stiffness [(1,543.37±61.41) N/mm] and yield load [1,338.57 (1,282.00, 1,353.80) N] of ACCSR group were significantly smaller than those of CSR group [(3,797.63±156.15) N/mm and 4,059.95 (3,813.80, 4,090.89) N] ( P<0.05). The spinal rod fatigue tests showed that the respective loads of CSR and ACCSR passing the 2.5 million fatigue tests were 640.00 N and 320.00 N, both larger than the maximum force at the unilateral lumbar isthmus of a normal adult (198.72 N). There were no significant differences between the ACCSR group and the CSR group in the axial gripping capacity and torsional gripping capacity, as well as in stiffness and yield load of screws between the 2 groups ( P>0.05). Conclusions:In fixation of LS, although the yield load, stiffness and fatigue resistance of ACCSR are inferior to those of CSR, the biomechanical properties of the two sets of pedicle screw-rod internal fixation system are comparable. The fatigue resistance of ACCSR can meet the stress requirements of the normal human isthmus.

Objective:To evaluate the technical approach and application value of DynaCT biliary reconstruction with CT images fusion (DynaCT-CT fusion) for the treatment of complex hepatolithiasis.Methods:The data of 18 patients with complex hepatolithiasis admitted to the First Affiliated Hospital of Guangzhou Medical University from May 2022 to October 2022 were retrospectively analyzed, including 7 males and 11 females, aged (50.6±15.0) years. Preoperative DynaCT biliary reconstruction with CT images fusion was performed to guide the percutaneous transhepatic one-step biliary fistulation (PTOBF). The technical data, including the bile duct with stones identified by preoperative imaging, the actual bile duct with stones confirmed intraoperatively, the satisfied stone removal time for each targeted bile duct, the actual stone removal time for each targeted bile duct, the intraoperative identification of CT-negative stones, the postoperative complications and reoperation were analyzed.Results:In 18 patients, a total of 95 target bile ducts with stones were identified by preoperative DynaCT-CT fusion technology, involving the first, secondary and tertiary bile ducts. Preoperative CT identified 29 lesions of stones involving the first and secondary bile ducts. CT negative stones were confirmed in 5 patients by DynaCT-CT fusion. Bile duct stricture occurred in 12 patients. All procedures were completed without postoperative bile leakage or hemorrhage. A total of 82 lesions of stones were successfully removed with a removal time of (25.9±12.8) min. The satisfied stone removal time for each targeted bile duct was (10.1±7.6) min, and the actual stone removal time was (10.5±7.4) min. Immediate stone clearance was achieved in 13 patients. Biliary tract infection occurred in 2 patients, and 5 patients underwent reoperation for residual or recurrent stones.Conclusion:The DynaCT-CT fusion technology guided PTOBF is feasible and safe in patients with complex hepatolithiasis. It could effectively detect more stones, shorten the stone clearance time. DynaCT-CT fusion technology provides a new strategy for the treatment of hepatolithiasis.

Objective:To investigate the efficacy of elastic locking intramedullary nail (ELIN) in the treatment of mid clavicle fractures.Methods:From January 2014 to December 2020, the data of 61 patients with mid-clavicle fracture treated with ELIN were retrospectively analyzed. Among them, 38 patients were from the Fourth Central Hospital Affiliated to Nankai University and 23 were from the Second People's Hospital of Hulunbuir City. There were 36 males and 25 females, aged from 19 to 85 years (average, 54.5 years), 39 cases on the left side and 22 cases on the right side. According to Robinson's classification, there were 20 cases of type 2A2, 29 cases of type 2B1 and 12 cases of type 2B2. There was no nerve or vascular injury before operation. The postoperative evaluation measures included incision length, operation time, blood loss, fracture reduction, fracture healing time, ELIN removal time, shoulder Constant-Murley score, disabilities of the arm, shoulder, and hand (DASH) score, and related complications.Results:All patients were followed up for 13-51 weeks (average, 21.8 weeks). There were 34 cases of closed reduction and 27 cases of mini-open reduction, and the length of incision was 2.04±1.08 cm. The closed reduction operation time was 20.32±7.11 min, and the mini-open reduction operation time was 20.30±5.37 min. The intraoperative blood loss was 6.47±2.31 ml in the closed reduction group and 27.41±11.55 ml in the mini-open reduction group. Compared with the healthy side, the clavicle length of the affected side was shortened by 7.74%±3.51% of pre-operation and 0.71%±1.00% of post-operation, there was statistically significant difference in the length of clavicle shortening of pre- and post-operation ( t=3.84, P<0.001). The fracture healing time was 10.48±2.39 weeks. The removal time of ELIN was 13.39±2.69 weeks. At the last follow-up, the Constant-Murley score of shoulder joint was 98.87±1.74. The average of DASH score was 1.13 (range, 0-10). There were 18 cases of skin irritation after operation, of which 13 cases formed pressure sores at the tail end 3-6 weeks after the operation, and were treated with dressing change and keeping clean; 4 cases of skin irritation at the tail end formed bursitis, which disappeared after removal of the internal fixation. In 1 case, the tip of ELIN penetrated the anterior cortex from the proximal clavicle and stimulated the skin. Radiograms showed continuous callus at 4 weeks after operation, and there was no local tenderness on the physical examination, which reached the clinical healing standard, and the symptoms were relieved after the nail was removed. No serious complications such as neural and vascular injury, nail breaking, delayed healing, infection, numbness or discomfort in the subclavian area occurred in all cases, and all patients were satisfied or basically satisfied with the aesthetic of the skin appearance. Conclusion:Minimally invasive and microstress shielding fixation of mid-clavicle fracture with ELIN have the advantages of simple operation, minimally invasive, beautiful appearance, anti-short-shrinkage and rapid fracture healing etc. It is an effective surgical method for the treatment of mid-clavicle fractures.

Objective:To compare the efficacy of double thread elastic locking intramedullary nail (ELIN) and threaded elastic intramedullary nail (TEIN) in the treatment of mid-shaft clavicular fracture.Methods:From August 2017 to September 2020, 33 patients with mid-shaft clavicular fractures were treated with ELIN (double threaded nail group), including 14 males and 19 females, age 52.09±16.32 years old; Robinson classification: 20 cases of type 2A2, 6 cases of type 2B1, and 7 cases of type 2B2. Thirty-two patients were selected as the control group with TEIN fixation (single threaded nail group) during the same period, including 13 males and 19 females; age 43.25±15.03 years old; Robinson classification: 19 cases of type 2A2 and 5 cases of type 2B1, 8 cases of 2B2 type. The operation time, intraoperative incision length, fracture healing time, internal fixation removal time, Constant-Murley shoulder joint score, disabilities of the arm, shoulder, and hand (DASH) score, fracture reduction and postoperative complications were compared between the two groups.Results:The patients in both groups were followed up after operation, the double-threaded screw group was followed up for 16-48 weeks (average, 23.7 weeks), and the single threaded nail group was followed up for 15-51 weeks (average, 22.9 weeks). The operation time of the double threaded nail group and the single threaded nail group were 19.45±6.74 min and 19.59±4.98 min, and the length of the incision was 1.70±0.79 cm and 1.73±0.84 cm. The fracture healing time were 12.12±1.29 weeks and 13.88±1.84 weeks. The internal fixation removal time was 13.09±1.31 weeks and 15.69±1.94 weeks. The Constant-Murley shoulder score was 93.18±3.78 points and 90.09±4.03 points, and the DASH scores were 1.49± 0.49 points and 3.85±1.13 points; There was no significant difference in operation time and incision length between the two groups ( t=0.01, 0.19; P>0.05), while fracture healing ( t=3.70, P<0.001), internal fixation removal time ( t=6.34, P<0.001), Constant-Murley shoulder score ( t=3.19, P<0.001), DASH score ( t=10.95, P<0.001) differences were statistically significant. The length of the clavicle on the healthy side was 16.38±1.09 cm in the double threaded nail group, and the length of the clavicle on the affected side after internal fixation removal was 16.33±1.12 cm. There was no obvious shortening deformity on the affected side, and there was no significant difference in the length of the clavicle between the two sides ( t=1.57, P=0.127). The clavicle lengths of the healthy side and the affected side after internal fixation removal in the single threaded nail group were 16.55±1.12 cm and 15.12±1.18 cm, and the difference was statistically significant ( t=8.02, P<0.001). The postoperative shortening values of the double-threaded screw group and the single-threaded screw group were 9.47±2.12 mm and 17.41±2.42 mm, and the difference was statistically significant ( t=14.07, P<0.001). Postoperatively, 5 cases of bursitis and 2 cases of skin irritation occurred in the double threaded nail group; While 6 cases of bursitis, 3 cases of skin irritation, 4 cases of shortening malunion, and 1 case of broken nail occurred in the single threaded nail group (fracture delayed union after replacement of internal fixation); the other patients did not experience screw retraction, wound infection, delayed fracture union or nonunion, neurovascular injury, and achieved osseous union. Conclusion:Both elastic intramedullary nails are effective surgical methods for the treatment of middle clavicle fractures, and the operation time is short and minimally invasive. However, compared with the TEIN, the fracture healing time of the double-threaded ELIN is shorter, the internal fixation removal time is earlier, the shoulder joint and upper limb function is better, and the shortening deformity is less likely to occur.

BACKGROUNDS: At present, there is no consensus on the induction methods in term pregnancy with borderline oligohydramnios. This study aimed to compare the effectiveness and pregnancy outcomes of labor induction with dinoprostone or single-balloon catheter (SBC) in term nulliparous women with borderline oligohydramnios. METHODS: We conducted a retrospective cohort study from January 2016 to November 2018. During the study period, a total of 244 cases were enrolled. Of these, 103 cases were selected for induction using dinoprostone and 141 cases were selected for induction with SBC. The pregnancy outcomes between the two groups were compared. Primary outcomes were successful vaginal delivery rates. Secondary outcomes were maternal and neonatal adverse events. Multivariate logistic regression was used to assess the risk factors for vaginal delivery failure in the two groups. RESULTS: The successful vaginal delivery rates were similar between the dinoprostone group and the SBC group (64.1% [66/103] vs. 59.6%, [84/141] P = 0.475), even after adjustment for potential confounding factors (adjusted odds ratio [aOR]: 1.07, 95% confidence interval [CI]: 0.57-2.00, P = 0.835). The incidence of intra-amniotic infection was lower in the dinoprostone group than in the SBC group (1.9% [2/103] vs. 7.8%, [11/141] P < 0.001), but the presence of non-reassuring fetal heart rate was higher in the dinoprostone group than in the SBC group (12.6% [13/103] vs. 0.7%, [1/141] P < 0.001). Multivariate logistic regression showed that nuchal cord was a risk factor for vaginal delivery failure after induction with dinoprostone (aOR: 6.71, 95% CI: 1.96-22.95). There were three factors related to vaginal delivery failure after induction with SBC, namely gestational age (aOR: 1.51, 95% CI: 1.07-2.14), body mass index (BMI) >30 kg/m2 (aOR: 2.98, 95% CI: 1.10-8.02), and fetal weight >3500 g (aOR: 2.49, 95% CI: 1.12-5.50). CONCLUSIONS Term nulliparous women with borderline oligohydramnios have similar successful vaginal delivery rates after induction with dinoprostone or SBC, with their advantages and disadvantages. In women with nuchal cord, the risk of vaginal delivery failure is increased if dinoprostone is used in the induction of labor. BMI >30 kg/m2, large gestational age, and estimated fetal weight >3500 g are risk factors for vaginal delivery failure after induction with SBC.

Objective:To evaluate the effect of femoral stable interlocking intramedullary nail (FSIIN) and proximal femoral nail anti-rotation (PFNA) in the treatment of anterograde intertrochanteric fractures.Methods:From June 2015 to December 2020, 68 cases with surgically treated of femoral intertrochanteric fractures were included. Among them, there were 37 cases (17 males and 20 females) in proximal femoral nail antirotation (PFNA) group, and the age ranged from 48 to 78 years (62.9±7.1 years); 18 cases were on the left and 19 cases on the right; AO/OTA classification: 16 cases of A1 type and 21 cases of A2 type. And there were 31 cases (18 males and 13 females) in FSIIN group without distal locking, the age ranged from 47 to 84 years (62.4±8.6 years); 15 cases were on the left and 16 cases on the right; AO/OTA classification: 11 cases of A1 type and 20 cases of A2 type. Fracture fixation time, incision length and number, intraoperative blood loss, fracture healing time, visual analogue scale (VAS) and Harris scores at the last follow-up were compared between the two fixation methods.Results:Both groups were followed up, and the follow-up time was 15.3±3.9 months in the FSIIN group and 15.7±3.9 months in the PFNA group, and the difference was not statistically significant ( t=0.42, P=0.675). In FSIIN group, the fracture fixation time was 26.6±11.5 min, the total incision length was 7.6±1.8 cm, the intraoperative blood loss was 107.6±42.8 ml and the fracture healing time was 10.1±1.3 weeks. In PFNA group, the fracture fixation time was 40.3±10.8 min, the total incision length was 12.2±1.8 cm, the intraoperative blood loss was 209.4±52.0 ml and the fracture healing time was 16.3±1.6 weeks. In FSIIN group, the fracture fixation time ( t=3.46, P<0.001), total incision length ( t=2.39, P=0.020), intraoperative blood loss ( t=3.16, P<0.001), fracture healing time ( t=2.80, P<0.001) were all less than those in PFNA group, and the difference was statistically significant. The VAS score of FSIIN group was 1.4±0.5 points, and that of PFNA group was 1.6±0.6 points, and the difference was not statistically significant ( t=0.68, P=0.503). The Harris score was 84.5±2.2 in FSIIN group and 83.3±2.5 in PFNA group, and the difference was not statistically significant ( t=0.63, P=0.530). At the last follow-up, 29 patients in the FSIIN group were very satisfied with the operation, and 2 patients were satisfied with the operation, with a satisfaction rate of 100%. In PFNA group, 30 patients were very satisfied with the operation, 7 patients were satisfied with the operation, and the satisfaction rate was 100%. Conclusion:Compared with PFNA, micro-invasive and micro-stress shielding methodes of FSIIN in the fixation of anterograde intertrochanteric fractures is more minimally invasive, simple, time-saving, less bleeding, less risk, less pain, minimal stress shilding and enhanced recovery after surgery. The effect of treatment is similar in FSIIN and PFNA group.

ObjectiveTo observe the effects of Internet plus continuous rehabilitation nursing on older patients after lumbar fusion. MethodsFrom January, 2018 to August, 2021, 157 older patients after transforaminal lumbar interbody fusion (TLIF) in Department of Orthopedics, Chongqing General Hospital were retrospectively studied. A total of 66 patients accepting routine continuous rehabilitation nursing care were as control group, and 91 patients accepting internet plus continuous rehabilitation nursing care were as intervention group. They were assessed with Visual Analog Scale for pain (VAS), Oswestry Disability Index (ODI), Huaxi Emotional-distress Index (HEI) and Adult Health Self-management Skill Rating Scale (AHSMSRS) before, and one and three months after intervention. The compliance and nursing satisfaction were investigated with self-made questionnaire three months after intervention, and the postoperative complications were recorded. ResultsA total of 148 patients finished follow-up of three months, including 61 patients for the control group and 87 patients for the intervention group. The VAS, ODI, HEI and AHSMSRS scores improved in both groups one and three months after intervention (F > 85.4, P < 0.001), and improved more in the intervention group than in the control group (|t| > 3.645, P < 0.001). Both the compliance and nursing satisfaction were better in the intervention group than in the control group (χ² > 5.478, P < 0.05), and no postoperative complication was observed in both groups. ConclusionInternet plus continuous rehabilitation nursing can promote the recovery of function, pain and psychological emotion, ability of self-management, compliance, and nursing satisfaction.

Different centers collected and summarized their data in 2017 and sent back the questionnaires for summary. RESULTS: A total of 8 766 AA patients were enrolled from 43 medical centers, including 4 711 males (53.7%) with median age of 39 years and 958 (10.9%) patients over 65 years old. Of 8 776 patients, 5 677 cases (64.6%) received one or more imaging examinations, and the other 3 099 (35.4%) did not receive any imaging examination. A total of 1 858 (21.2%) cases received medical treatment, mainly a combination of nitroimidazoles (1 107 cases, 59.8%) doublet regimen, followed by a single-agent regimen of non-nitroimidazoles (451 cases, 24.4%), a nitroimidazole-free doublet regimen (134 cases, 7.2%), a triple regimen of combined nitroimidazoles (116 cases, 6.3%), nitroimidazole alone (39 cases, 2.1%) and nitroimidazole-free triple regimen (3 cases, 0.2%). Of the 6 908 patients (78.8%) who underwent surgery, 4 319 (62.5%) underwent laparoscopic appendectomy and 2589 (37.5%) underwent open surgery. Ratio of laparotomy was higher in those patients under 16 years old (392 cases) or over 65 years old (258 cases) [15.1%(392/2 589) and 10.0%(258/2 589), respectively, compared with 8.5%(367/4 316) and 8.0%(347/4 316) in the same age group for laparoscopic surgery, χ²=91.415, P<0.001; χ²=15.915,P<0.001]. Patients with complicated appendicitis had higher ratio of undergoing open surgery as compared to those undergoing laparoscopic surgery [26.7%(692/2 589) vs. 15.6%(672/4 316), χ²=125.726, P<0.001].The cure rates of laparoscopic and open surgery were 100.0% and 99.8%(2 585/2 589) respectively without significant difference (P=0.206). Postoperative complication rates were 4.5%(121/2 589) and 4.7%(196/4 316) respectively, and the difference was not statistically significant (χ²=0.065, P=0.799). The incidence of surgical site infection was lower (0.6% vs. 1.7%, χ²=17.315, P<0.001), and hospital stay was shorter [6(4-7) days vs. 6(5-8) days, U=4 384 348.0, P<0.001] in the laparoscopic surgery group, while hospitalization cost was higher (median 12 527 yuan vs. 9 342 yuan, U=2 586 809.0, P<0.001). CONCLUSIONS The diagnosis of acute appendicitis is still clinically based, supplemented by imaging examination. Appendectomy is still the most effective treatment at present. Laparoscopic appendectomy has become the main treatment strategy, but anti-infective drugs are also very effective.

Objective: To evaluate the postoperative quality of life after surgery of patients with hepatic hemangioma. Methods: The retrospective and descriptive study was conducted. The clinical data of 104 patients who underwent surgery for hepatic hemangioma at Shengjing Hospital of China Medical University from September 2011 to February 2017 were collected. There were 28 males and 76 females, aged (49±8)years, with a range of 27-78 years. Enucleation of hepatic hemangioma or hepatectomy was selected according to tumor location of patients. Observation indicators: (1) surgical and postoperative situations; (2) assessment of quality of life in patients; (3) assessment of quality of life in patients comorbid with other chronic digestive diseases. Measurement data with normal distribution were represented as Mean±SD, and measurement data with skewed distribution were represented as M (range). Repeated data were analyzed using repeated ANOVA. Count data were represented as absolute numbers. Results: (1) Surgical and postoperative situations: of 104 patients, 67 underwent enucleation of hepatic hemangioma, 37 underwent hepatectomy. The tumor diameter, volume of intraoperative blood loss, duration of postoperative hospital stay were (10±4)cm, 200 mL (range, 10-3 000 mL), (11±5)days. Seven patients had complications, including 5 of massive abdominal ascites, 1 of abdominal infection, and 1 of pulmanory obstruction. There was no death occurred. (2) Assessment of quality of life in patients with hepatic hemangioma: the total scores of Gastrointestinal-related Quality of Life Index (GIQLI), the scores of subjective symptoms, physiological status, mental and psychological status, and social activities were 121.0±8.3, 69.2±4.1, 18.5±2.6, 19.5±1.8, and 13.8±1.4 at preoperation. The above indices were 121.9±6.9, 71.2±3.8, 17.2±2.5, 19.6±2.3, and 13.8±1.3 of 104 patients with hepatic hemangioma at one month after surgery, respectively. The above indices were 127.8±6.2, 73.2±3.6, 19.8±2.5, 20.8±2.4, and 14.1±1.0 at 6 months after surgery. There were significant differences in changing trends of above indices (F=68.4, 64.6, 71.4, 17.8, 3.3, P<0.05). The scores of subjective symptoms and physiological status at one month after surgery showed significant differences compared with those of preoperation (t=-5.780, 6.640, P<0.05), but the total scores of GIQLI, the scores of mental and psychological status, and social activities showed no difference (t=-1.569, -0.705, 0.240, P>0.05). The total scores of GIQLI, scores of subjective symptoms, physiological status, and mental and psychological status at 6 months after surgery showed significant differences compared with those of preoperation (t=-8.897, -9.919, -5.375, -5.024, P<0.05), but the score of social activities showed no difference(t=-1.919, P>0.05). The total scores of GIQLI, the scores of subjective symptoms, physiological status, mental and psychological status, and social activities at 6 months after surgery were significantly different from those at one month after surgery (t=-10.835, -6.787, -12.277, -4.560, -2.476, P<0.05). (3) Assessment of quality of life in hepatic hemangioma patients comorbid with other chronic digestive diseases: 29 of 104 patients were comorbid with chronic gastritis, biliary diseases, and appendicitis. For the 29 patients comorbid with other chronic digestive diseases, the total scores of GIQLI, the scores of subjective symptoms, physiological status, mental and psychological status, and social activities were 117.5±7.5, 67.8±4.2, 17.4±2.2, 19.0±1.5, and 13.2±1.3 at preoperation. The above indices were 118.7±6.9, 69.5±4.5, 16.7±2.0, 19.2±1.9, and 13.2±1.3 at one month after surgery, respectively. The above indices were 124.6±6.5, 70.9±4.5, 19.8±2.1, 19.9±2.4, and 14.0±0.9 of 29 patients comorbid with other chronic digestive diseases at 6 months after surgery. There were significant differences in changing of the total scores of GIQLI, the scores of subjective symptoms, physiological status, and social activities (F=15.0, 9.0, 27.6, 7.5, P<0.05), except the score of mental and psychological status (F=1.6, P>0.05) . The scores of subjective symptoms and physiological status at one month after surgery showed significant differences compared with those of preoperation (t=-2.612, 2.191, P<0.05), but the total scores of GIQLI, the scores of mental and psychological status, and social activities showed no difference (t=-1.128, -0.587, -0.157, P>0.05). The total scores of GIQLI, scores of subjective symptoms, physiological status, and social activities at 6 months after surgery showed significant differences compared with those of preoperation (t=-4.002, -3.441, -4.604, -3.266, P<0.05), but the score of mental and psychologica status showed no difference (t=-1.522, P>0.05). The total scores of GIQLI, the scores of subjective symptoms, physiological status, and social activities at 6 months after surgery were significantly different from those at one month after surgery (t=-4.819, -2.313, -7.081, -3.172, P<0.05), but the score of mental and psychological status had no significant difference (t=-1.154, P>0.05). Conclusions The quality of life in patients with hepatic hemangioma can be improved by surgery. Surgical treatment is still effective for improvement of the total scores of GIQLI, the scores of subjective symptoms, physiological status, and social activities for those combined with other digestive diseases.

Objective: To compare the curative effect between Elastic Locking Intramedullary Nail (ELIN) and Anatomic Locking Plate (ALP) for the treatment of fracture in the mid-shaft of clavicle (Classification AO/OTA:2A/2B). Methods: Data of 47 cases of 2A/2B clavicular fractures who were treated with operation from January 2014 to December 2016 were retrospectively analyzed. The patients were divided into ELIN group and ALP group according to different fixation methods. There were 23 cases in ELIN group, 14 male and 9 female, aged from 19 to 85 years (average, 55.26 years). 14 cases on the left side and 9 cases on the right side. There were 6 cases of type 2A and 17 cases of type 2B. There were 24 cases in the ALP group, 18 male and 6 female, aged from 15 to 71 years (average, 51.25 years). 16 cases on the left side and 8 cases on the right side. There were 9 cases of type 2A and 15 cases of type 2B. The operation time, intraoperative blood loss, length of skin incision, fracture healing time, extraction time of internal fixation, Constant-Murley score of shoulder joint, disabilities of the arm, shoulder, and hand (DASH) score, and complication incidence were compared between the two groups. Results: All the operations were successfully performed. The mean follow-up for the patients in the ELIN group was 19.35 weeks (range, 14-23 weeks). The mean follow-up for the patients in the ALP group was 53.13 weeks (range, 28-76 weeks). In the ELIN group, the operative time was 20.78 ± 7.71 min, the intraoperative blood loss was 13.26±9.72 ml, the length of incision was 1.57±1.24 cm, the fracture healing time was 10.39±2.39 weeks, the extraction time of internal fixation was 13.17±2.37 weeks, the Constant-Murley score of shoulder joint was 99.09±1.86, and the DASH score was 1.20±2.47. In the ALP group, the operative time was 57.79±11.56 min, the intraoperative blood loss was 69.17±46.24 ml, the length of incision was 9.67±2.90 cm, the fracture healing time was 14.21±4.05 weeks, the extraction time of internal fixation was 47.38±10.46 weeks, the Constant-Murley score of shoulder joint was 98.00±2.17, and the DASH score was 0.89±1.65. The operation time (t=12.856, P=0.000), intraoperative blood loss (t=5.791, P=0.000) in the ELIN group were less than that of ALP group. The length of incision was significantly smaller in ELIN group than that of ALP group (t=12.549, P=0.000). The fracture healing time was earlier in ELIN group than that of ALP group (t=3.566, P=0.002). The extraction time of internal fixation was obviously earlier in ELIN group than that of ALP group (t=15.603, P=0.000). Constant-Murley score of shoulder joint and DASH score showed no significant difference. No delayed healing, no infection was found in the ELIN group, however skin irritation and tail bursitis were found in 6 cases, 3-6 weeks after the operation. The dressing was changed, kept clean. Skin irritation and tail bursitis disappeared, after the extraction of the internal fixation. There were 2 cases of delayed healing in the ALP group. After prolonged observation, the 2 cases healed. The healing time was extended to 24 and 27 weeks, respectively. There was 1 case of infection, 1 case of poor skin healing in the ALP group. The infected patient was treated with debridement and sensitive antibiotics, and the patient with poor skin healing was treated with dressing change. All the patients had wound healing about 4 weeks after surgery. 2 cases of skin irritation in the ALP group disappeared, after the extraction of the internal fixation. Conclusion Both ALP and ELIN are effective methods for the treatment of mid-shaft clavicular fracture. ELIN group has the advantages of more minimally invasive, faster union, shorter internal fixation time, better appearance, and lower medical cost. However, the ELIN group also had skin irritation and temporary bursitis.
