OBJECTIVE: To compare the efficacy of percutaneous pedicle screw combined with unilateral nail placement combined with bone cement strengthening and bilateral nail placement in the treatment of osteoporotic thoracic and lumbar fractures. METHODS: A retrospective case-control study was used to analyze the clinical data of 78 patients with osteoporotic thoracic and lumbar fractures admitted from October 2017 to May 2019. According to the surgical method, it was divided into percutaneous pedicle screw combined with unilateral nail placement combined with unilateral bone cement strengthening group(bone cement group) and percutaneous pedicle screw combined with bilateral nail placement(screw group). In the bone cement group, 40 patients included 16 males and 24 females, with a mean age of (62.1±8.1) years old. In the screw group, 38 patients included 18 males and 20 females with a mean age of (65.1±9.3) years old. The operation time, intraoperative blood loss, length of hospital stay and postoperative complications were compared between two groups. The kyphosis Cobb angle, anterior edge height ratio, central height ratio and pain visual analogue score(VAS) were compared. RESULTS: All patients were followed up for 25 to 36 months. The operation time (70.1±17.3) min of the cement group was shorter than that of the screw group (78.6±18.2) min(P<0.05). There were no significant differences in intraoperative blood loss and length of hospital stay(P>0.05). The VAS in the cement group 1 year 1.5±0.5 and the latest follow-up 0.5±0.3 after operation were lower than 1 year 1.8±0.3 and the latest follow-up 0.8±0.4 in the screw group(P<0.05). The kyphosis Cobb angle, anterior edge height ratio, central height ratio in bone cement group, 1 year (6.2±1.2)°, (86.6±3.5)%, (91.1±2.5)%, the last follow-up (6.4±0.7)°, (85.5±3.3)%, (90.5±6.3)% were better than that of the screw group 1 year (6.8±1.4)°, (83.1±2.4)%, (89.9±3.4)% and the latest follow-up (7.1±1.1)°, (82.6±4.1)%, (87.6±5.9)%(P<0.05). There were 3 cases of bone cement leakage in the cement group, all of which had no clinical symptoms;and 2 cases of pedicle screws were extracted in the screw group, and the screws were removed at the last follow-up. CONCLUSION Percutaneous pedicle screw combined with unilateral nail placement combined with bone cement strengthening and bilateral nail placement in the treatment of osteoporotic thoracic and lumbar compression fractures in the elderly can achieve satisfactory efficacy and effectively relieve the pain of patients, but the former internal fixation system is more stable, and the long-term follow-up can effectively maintain the height of the anterior middle column and the correction of kyphosis deformity, and the incidence of chronic low back pain is lower.

OBJECTIVE: To explore the efficacy and safety of human epidermal growth factor gel in the treatment of pin tract infections after surgery in patients with severe spinal deformity. METHODS: A retrospective case-control study was conducted to analyze the clinical data of 26 patients with pin tract infections after skull-pelvic ring traction for severe spinal deformity admitted from February 2019 to May 2022. Among them, 11 were male and 15 were female;the age ranged from 18 to 31 years, with an average of (24.1±4.3) years;the Cobb angle ranged 80.3° to 120.7°, with an average of (88.6±10.2)°;there were 52 iliac traction pins, 104 pin tract openings, and 38 pin tract infections. According to the Checketts-Otterbum classification, there were 11 infections of gradeⅠ, 13 infections of gradeⅡ, 10 infections of grade Ⅲ, and 4 infections of grade Ⅳ. The patients were divided into the conventional dressing change group (13 cases) and the growth factor group (13 cases) by coin flipping. Clinical efficacy was evaluated by recording the visual analogue scale(VAS) score during dressing change, duration of dressing change, cost of dressing change, positive rate of bacterial culture, wound improvement rate, and wound improvement time. RESULTS: There were no statistically significant differences in VAS or duration of dressing change between the two groups (P>0.05). The cost of dressing change was (800.0±59.5) yuan in the conventional dressing change group and (1 179.5±80.9) yuan in the growth factor group, with a statistically significant difference (P<0.05). There was no statistically significant difference in the positive rate of bacterial culture between the two groups (P>0.05). In the conventional dressing change group, within 20 pin tract infections, 2 infections achieved wound healing, 7 infections showed improvement, and 11 infections were ineffective;in the growth factor group, within 18 pin tract infections 5 infections achieved wound healing, 8 infections showed improvement, and 5 infections were ineffective, with a statistically significant difference between the two groups (P<0.05). The wound healing time was (22.8±4.9) days in the conventional dressing change group and (14.2±2.5) days in the growth factor group, with a statistically significant difference (P<0.05). No complications occurred in either group. CONCLUSION The application of human epidermal growth factor gel in the treatment of pin tract infections after skull-pelvic ring surgery in patients with severe spinal deformity is easy to operate, does not increase patient pain, and has significant efficacy. It shortens wound healing time, effectively promotes wound healing, and has good safety and high cost-effectiveness.

Congenital orofacial cleft, the most common birth defect in the maxillofacial region, exhibits a wide range of prognosis depending on the severity of deformity and underlying etiology. Non-syndromic congenital orofacial clefts typically present with milder deformities and more favorable treatment outcomes, whereas syndromic congenital orofacial clefts often manifest with concomitant organ abnormalities, which pose greater challenges for treatment and result in poorer prognosis. This consensus provides an elaborate classification system for varying degrees of orofacial clefts along with corresponding diagnostic and therapeutic guidelines. Results serve as a crucial resource for families to navigate prenatal screening results or make informed decisions regarding treatment options while also contributing significantly to preventing serious birth defects within the development of population.

OBJECTIVE: To observe the early clinical efficacy of the zero-remember cervical Solis fusion device in the treatment of adjacent segment degeneration(ASD) revision after anterior cervical discectomy and fusion(ACDF). METHODS: A retrospective analysis was performed for 13 patients with adjacent spondylosis after anterior cervical discectomy bone graft fusion with Solis fusion device, including 5 males and 8 females, aging from 56 to 78 years old. The patients had intractable neck pain or superficial paresthesia of upper extremities before operation, and the effect of conservative treatment was not good. The operation time, intraoperative blood loss and postoperative complications were recorded. Before operation, 1 week postoperative and final follow-up, the visual analogue scale(VAS) and Japanese Orthopaedic Association(JOA) scores were used to assess clinical efficacy. X-ray and CT of the cervical spine were performed to measure and evaluate the height of the intervertebral space and intervertebral fusion. RESULTS: All patients were followed up from 18 to 36 months. All 13 patients successfully completed revision surgery with single gaps. The operation time was 63 to 93 min, the intraoperative blood loss was 15 to 83 ml. The pain VAS was reduced from 4 to 7 points before surgery to 1 to 3 points at 1 week and 1 to 2 points at the final follow-up. The height of the intervertebral space was increased from 5.2 to 7.2 mm before surgery to 6.4 to 8.0 mm at 1 week after surgery and 6.4 to 7.9 mm at the final follow-up. The JOA score was increased from 11 to 17 points before surgery to 13 to 17 points at 1 week after surgery and 16 to 17 points at the final follow-up visit. At the final follow-up, AP and lateral X-ray films of cervical spine showed homogeneous bone fusion of the Solis fusion. One patient developed transient left upper limb weakness after surgery, which recovered at follow-up, and all patients had no dysphagia, incision hematoma or infection, and displacement. CONCLUSION The early clinical efficacy of Solis fusion device in the treatment of orthospondylosis after anterior cervical intervertebral fusion is satisfactory, and it has the advantages of less surgical trauma, adequate decompression, high osseointegration rate and fewer complications, which can provide a new option for minimally invasive treatment of orthospondylosis after cervical spine surgery.

OBJECTIVE: To investigate the clinical effect of aconite-isolated moxibustion at Yongquan (KI 1) combined with rivaroxaban for lower extremity venous thrombosis after total knee arthroplasty and the influence on hypercoagulation. METHODS: Seventy-three patients of knee osteoarthritis with lower extremity venous thrombosis after total knee arthroplasty (KOA) were randomly divided into an observation group (37 cases, 2 cases dropped off) and a control group (36 cases, 1 case dropped off). The patients in the control group took orally rivaroxaban tablets, 10 mg a time, once a day. On the basis of the treatment as the control group, the aconite-isolated moxibustion was applied to Yongquan (KI 1) for the patients of the observation group, once daily and 3 moxa cones were used in each treatment. The duration of treatment was 14 days in both groups. Before treatment and 14 days into treatment, the ultrasonic B test was adopted to determine the conditions of lower extremity venous thrombosis in the two groups. Before treatment, 7 and 14 days into treatment, the coagulation indexes (platelet [PLT], prothrombin time [PT], activated partial prothrombin time [APTT], fibrinogen [Fib] and D-dimer[D-D]), the blood flow velocity of the deep femoral vein and the circumference of the affected side were compared between the two groups separately, and the clinical effect was evaluated. RESULTS: Fourteen days into treatment, the venous thrombosis of the lower extremity was relieved in both groups (P<0.05), and that of the observation group was better than the control group (P<0.05). Seven days into treatment, the blood flow velocity of the deep femoral vein was increased compared with that before treatment in the observation group (P<0.05), and the blood flow rate in the observation group was higher than that in the control group (P<0.05). Fourteen days into treatment, PT, APTT and the blood flow velocity of the deep femoral vein were increased in the two groups compared with those before treatment (P<0.05); and PLT, Fib, D-D and the circumference of the limb (knee joint, 10 cm above the patella and 10 cm below the patella) were all reduced in the two groups (P<0.05). Compared with the control group 14 days into treatment, the blood flow velocity of the deep femoral vein was higher (P<0.05), PLT, Fib, D-D and the circumference of the limb (knee joint, 10 cm above the patella and 10 cm below the patella) were all lower in the observation group (P<0.05). The total effective rate was 97.1% (34/35) in the observation group, higher than 85.7% (30/35) in the control group (P<0.05). CONCLUSION Aconite-isolated moxibustion at Yongquan (KI 1) combined with rivaroxaban can effectively treat lower extremity venous thrombosis after total knee arthroplasty, relieve hypercoagulation, accelerate the blood flow velocity and alleviate swelling of the lower extremity in the patients with knee osteoarthritis.

Objective: To explore the surgical methods and clinical outcomes of severe angular kyphosis with the length of the spinal cord constant in the osteotomy area. Methods: Clinical data from 20 patients with severe angular kyphosis who underwent surgical treatment from January 2017 to December 2020 in the Department of Spinal Surgery,Hangzhou Xiaoshan District Hospital of Traditional Chinese Medicine were retrospectively analyzed. There were 11 males and 9 females, aged (28.5±8.9) years (range:17 to 46 years).There were 15 cases with congenital angular kyphosis,5 cases with tuberculous angular kyphosis.The angle of kyphosis was (107.1±12.9)° (range:93.2° to 131.4°).Frankel classification:2 cases with grade B,4 cases with grade C,3 cases with grade D.The kyphotic vertex is located at the T₉ to T₁₂ segments.Pedicle screws were placed in 3 or 4 adjacent segments at the proximal and distal kyphosis apex of the patients using a surgical navigation system.Piezosurgery combined with a grinding drill was used to complete the osteotomy in the apical vertebral region.Titanium mesh or artificial vertebral body was implanted,and the osteotomy surface was closed using this as the fulcrum to complete osteotomy.Spinal X-ray examination was performed before surgery,immediately after surgery and at the last follow-up,and sagittal and coronal Cobb angle,sagittal and coronary balance parameters,anterior vertebral height,posterior vertebral height,and spinal cord length were measured.Pulmonary function,visual analogue scale (VAS),and Oswestry's disability index (ODI) were collected and estimated before and after treatment.The analysis of variance of repeated measurement data was used for each evaluation index before and after treatment,and the t test was used for pairwise comparison. Results: All patients successfully completed surgery,with artificial vertebral body in 11 cases and double titanium mesh in 9 cases.The follow-up time was (28.2±2.3) months (range:26 to 31 months).Sagittal vertical axis improved from (46.9±13.7)mm(range:21.7 to 75.7 mm) before surgery to (10.7±5.5)mm (range:3.6 to 28.1 mm) after surgery,and (11.0±5.7)mm(range:3.6 to 29.3 mm) at the last follow-up,the differences were statistically significant compared to before surgery (all P<0.01).The mean kyphotic Cobb angle was corrected from (107.1±12.9) ° (range:93.2 ° to 131.4°) before surgery to (30.6±8.5) ° (range:20.0 ° to 47.8 °) after surgery (all P<0.01),and (32.1±8.7) ° (range:18.2 ° to 50.8°) at the last follow-up,the differences were statistically significant compared to before surgery(all P<0.01).The anterior vertebral height improved from (14.2±2.9)mm(range:11.04 to 23.6 mm) before surgery to (45.3±7.5)mm(range:29.4 to 56.5 mm) after surgery,and (44.3±6.8)mm(range:29.6 to 56.0 mm) at the last follow-up,the differences were statistically significant compared to before surgery (all P<0.01).The posterior vertebral height was improved from (51.8±5.3)mm (range:43.1 to 61.4 mm)before surgery to (57.6±4.7)mm (range:45.7 to 64.1 mm)after surgery,and (56.3±5.0) mm (range:49.7 to 68.5 mm) at the last follow-up,the differences were statistically significant compared to before surgery (all P<0.01).The spinal cord length of the osteotomy segment was (73.1±12.0)mm (range:56.8 to 98.4 mm) before surgery and (74.8±12.8)mm (range:53.5 to 100.2 mm) after surgery and (75.2±13.7)mm (range:53.9 to 102.4 mm) at the last follow-up,the difference was not statistically significant among them(F=0.144,P=0.866).The ODI and VAS scores improved significantly after surgery and at the last follow-up,and the differences were statistically significant (all P<0.01). Conclusion: The posterior vertebral column resection technique combined with titanium mesh or an artificial vertebral body implant for the treatment of severe angular kyphosis can significantly improve the kyphosis,neurological function,and life quality of patients without affecting the length of the spinal cord.

Anterior cervical fusion surgery is the first choice for spine surgeons in the treatment of cervical spine diseases. It has significant effects in treating cervical degenerative diseases, trauma and tumors and other cervical diseases. In anterior cervical fusion, it is necessary to use a distractor to properly distract the intervertebral space, so as to fully expose and relieve the compressive factors, restore the physiological height, curvature and stability of the lesion segment, and achieve the best surgical effect. However, there is currently no consensus on the standard distraction height for the intervertebral space during anterior cervical surgery. This article reviewsed the progress of intervertebral space height in anterior cervical fusion from three dimensions:the relationship between intervertebral space height and cervical disc degeneration mechanism, the selection of intervertebral space height during operation, the recovery of intervertebral space height and the postoperative effect, so as to provide theoretical basis and reference for spinal surgeons when performing intervertebral distraction during operation.

OBJECTIVE: To explore the safety and effectivity of ultrasonic bone knife in osteotomy of degenerative kyphosis. METHODS: The clinical data of 32 patients with degenerative kyphosis treated from February 2014 to May 2016 were retrospectively analyzed. There were 12 males and 20 females, aged 50 to 71 years with an average of (62.1±12.3) years. Preoperative Cobb angle was 25.3° to 36.7° with an average of (28.6±10.2) °. All patients underwent multi-segment Ponte osteotomy combined with posterior long segmental internal fixation. According to different osteotomy tools, the patients were divided into traditional tool group (group A, 18 cases) and ultrasonic bone knife group (group B, 14 cases). The operation time, laminectomy time, number of osteotomy segments, intraoperative blood loss, postoperative drainage, hospitalization time and postoperative complications were recorded.Visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to evaluate clinical outcomes before and 1 month after surgery. RESULTS: All the patients were followed up from 8 to 24 months with an average of 16.4 months. There were no significant differences in operative time and hospitalization time between two groups (>0.05). Intraoperative single laminectomy time of group A was more than that of group B (<0.05). The number of osteotomy segments in group A was less than that in group B (<0.05). Intraoperative blood loss and postoperative drainage in group A were more than that in group B (<0.05). There were no significant differences in VAS and ODI between two groups (>0.05). There were no dural, nerve and spinal cord injuries in both groups, and there were no complications such as improper operation of the instrument and nonunion of the osteotomy. CONCLUSION The use of ultrasonic bone knife for Ponte osteotomy is safe and effective. It can effectively save the time of single laminectomy while reducing the amount of intraoperative blood loss and postoperative drainage. The safety and clinical efficacy of ultrasonic bone knife are no less than traditional tools.

Objective:To investigate the related risk factors for biliary anastomotic stenosis after liver transplantation (LT) from donation after cardiac death(DCD) and therapeutic strategies.Methods:The data of 192 patients who received LT from DCD in First Hospital of Kunming from Jan 2010 to Jun 2018 were retrospectively analyzed. A total of 145 patients were enrolled, 85 males and 60 females, with average age 45 years. There was a biliary anastomotic stenosis in 8 cases and no stenosis in 137 cases. Their Chinese criterion for biliary anatomic stenosis, age, body mass index, liver fat, cold/warm ischemia time, unschedule cardiac arrest time, usage of vasopressors, high sodium in the donor were compared, and stenosis related factors were analysed by Spearman correlation analysis.Results:The stenosis was positively correlated with age ( r=0.229), body mass index ( r=0.204), lipoidosis ( r=0.239), duration of hot ischemia ( r=0.214), total duration of unplanned cardiac arrest ( r=0.401), use of booster drugs ( r=0.237), and preoperative donor hypernatremia ( r=0.557) (all P<0.05). Endoscopic biliary stent implantation is effective in the treatment of biliary anastomotic stenosis and has a high success rate. Conclusions:There are many factors related to biliary anastomotic stenosis after DCD liver transplantation, but the better donor maintenance, shorten cold/ warm ischemia time, improved anastomosis will be helpful to reduce biliary complications.As the same time, endoscopic biliary stent placement is the preferred way to treat biliary anastomotic stenosis.
