ObjectiveTo observe the short-term and long-term efficacy of traditional Chinese medicine （TCM） surgical operations in treating mixed hemorrhoids. MethodsA multi-center retrospective cohort study was conducted， collecting clinical data from 17，831 mixed hemorrhoid surgery patients in 8 top-tier TCM hospitals in Jiangsu Province. Standardized and structured datasets were obtained through artificial intelligence models. Patients who underwent western surgical treatment were categorized into the western surgery group （11,646 cases）， and those receiving TCM surgical operations were categorized into the TCM surgery group （6185 cases）. Propensity score matching （1∶1 matching） was used to balance baseline data between groups. The primary outcome was the one-year recurrence rate， and secondary outcomes included the main symptoms （rectal bleeding， degree of prolapse） and secondary symptoms （anal distension， anal edema， wound secretion and exudation， anal stenosis， residual skin tags， perianal itching， and anal pain） measured on days 7， 28， and 60 after discharge. ResultsAfter matching， 2194 patients were included in each group. Symptom scores showed that at 28 days after discharge， the TCM surgical group had superior improvement in rectal bleeding ［OR=5.786， 95%CI （3.092，10.827）］， degree of prolapse ［OR=4.510， 95%CI （1.649，12.333）］， and anal edema ［OR=3.188， 95%CI （1.295，7.845）］ compared to the western surgical group. At 60 days post-discharge， the TCM group still showed advantages in improving rectal bleeding ［OR=5.237， 95%CI （1.077，25.464）］ and anal pain ［OR=11.697， 95%CI （1.186，115.336）］ （P＜0.05）. Long-term follow-up showed that the one-year recurrence rate in the TCM surgery group was 1.1% （8/726）， while that in the western surgery group was 2.3% （10/444）， with no statistically significant difference between the two groups （P＞0.05）. ConclusionBased on real-world data， TCM surgical treatment for mixed hemorrhoids shows significant short-term symptom improvement， particularly in terms of hemostasis， reducing swelling， and alleviating prolapse of anal masses.

Objective:To investigate the effectiveness of the modified Bikini approach in the fixation of acetabular fracture with an integrated wing-shaped anatomical locking plate.Methods:A retrospective study was conducted to analyze the data of 54 patients with acetabular fracture who had been treated at Department of Trauma Orthopedics, Orthopedic Medical Center, The Third Hospital Affiliated to Southern Medical University from May 2017 to June 2021. The patients were divided into 2 groups based on different surgical approaches: an observation group [26 cases, 6 males, 20 females; aged 40.0 (29.8, 46.8) years] treated with fixation with an integrated wing-shaped anatomical locking plate through the modified Bikini approach, and a control group [28 cases, 10 males, 18 females; aged 34.5 (24.0, 43.5) years] treated with fixation with an integrated wing-shaped anatomical locking plate through the lateral-rectus approach. The incision length, operation time, intraoperative bleeding, length of hospital stay, quality of postoperative fracture reduction, visual analog scale (VAS) for pain, hip function, Vancouver Scar Scale (VSS) and Patient and Observer Scar Assessment Scale (POSAS) were compared between the 2 groups.Results:The differences in the preoperative general data between the 2 groups were not statistically significant, indicating comparability ( P>0.05). There were no statistically significant differences between the 2 groups either in terms of incision length, operation time, intraoperative bleeding, or hospital stay ( P>0.05). The 2 groups were not significantly different in the excellent/good rate of fracture reduction [100.0% (26/26) versus 92.9% (26/28)], VAS at 1 month postoperation [2.0(1.0, 3.0) versus 2.0(1.0, 3.0)], or the modified Merle d'Aubigné and Postel hip score at 12 months postoperation [13.5(12.3, 14.8) versus. 14.0(13.0, 15.0)] ( P>0.05). However, the VSS [4.50(4.00, 6.00)] and POSAS (29.85±10.05) at 12 months postoperation in the observation group were significantly lower than those in the control group [6.50(5.00, 8.25) and 37.11±11.75] ( P<0.05). Conclusion:In the fixation of acetabular fracture with an integrated wing-shaped anatomical locking plate, the modified Bikini approach can not only achieve as fine early clinical efficacy as the lateral-rectus approach, but also demonstrate the aesthetic advantages of smaller incision scar and more hidden incision.

Accurate classification of the acetabular injuries and appropriate treatment plan are great challenges for orthopedic surgeons because of the irregular anatomical structure of the acetabulum and aggregation of important vessels and nerves around it. Letournel-Judet classification system has been widely applied to classify acetabular fractures. However, there are several limitations, including incomplete inclusion of fracture types, difficulty in understanding and insufficient guidance for surgical treatment, etc. Serious complications such as traumatic arthritis are common due to wrong classification and diagnosis and improper selection of surgical strategy, which brings a heavy burden to the society and families. Three-column classification, based on anatomic characteristics, has advantages of containing more fracture types and being easy to understand, etc. To solve the problems existing in the diagnosis and treatment process based on Letournel-Judet classification, achieve accurate diagnosis and treatment of patients with acetabular fractures, and obtain satisfactory prognosis, the Orthopedic Trauma Emergency Center of Third Hospital of Hebei Medical University and the Trauma Orthopedic Branch of the Chinese Orthopedic Association organized experts from relevant fields to formulate the Expert consensus on the accurate diagnosis and treatment of acetabular fractures based on three-column classification ( version 2023) in terms of principles of evidence-based medicine. Based on the three-column classification, 15 recommendations were proposed, covering the diagnosis, treatment, complication prevention and management, etc, so as to provide reference for accurate diagnosis and treatment of acetabular fractures.

Treatment of a pelvic fracture may be delayed frequently because other systemic multiple injuries are more critical and need urgent operative management, rendering the pelvic fracture obsolete. Old pelvic fractures are often accompanied by chronic pain, pelvic ring deformity, limb shortening and gait instability, which usually need to be corrected by osteotomy. There have been no standard procedures but controversy lasts in osteotomy correction for pelvic malunion. This paper reviews the current related literature to summarize the advances in research of osteotomy correction for pelvic fracture malunion, hoping to provide reference for the treatment of old pelvic fractures.

Objective:To investigate the efficacy of intelligent visualization system (HoloSight Intelligent Visualization System) assisted reduction and screw fixation in the treatment of elderly pelvic fragility fracture.Methods:From January 2016 to December 2022, clinical data of 18 elderly patients aged over 75 years with pelvic fragility fractures surgically treated by our team were retrospectively analyzed. Among them, 11 cases were treated with closed reduction and hand-inserted percutaneous screw fixation to fix the posterior pelvic ring (control group), and 7 cases were treated with the assistance of the HoloSight intelligent visualization system for reduction and minimally invasive fixation (experimental group). In the control group, there were 3 males and 8 females with an age range of 75-94 years (mean age, 82±12 years). The pelvic fractures were classified as FFP type IIIa in 5 cases, IIIb in 2 cases, IIIc in 3 cases, and IV in 1 case. In the experimental group, there were 1 male and 6 females with an age range of 76-100 years (mean age. 83±14 years). The pelvic fractures were classified as FFP type IIIa in 4 cases, IIIc in 2 cases, and IV in 1 case. The surgical time, blood loss, effective intraoperative fluoroscopy times, fracture reduction quality (according to Matta standards), visual analogue scale (VAS), limb function rehabilitation (Majeed score) and postoperative complications were recorded and evaluated in both groups.Results:All patients underwent surgery successfully and were followed up for 6 months to 3 years(12 months on average), all pelvic fractures healed. Among the 7 cases of experimental group, a total of 13 screws were placed, and the adjustment times of guide pin for each screw were 3±1 times (range, 1-5 times), while 18 screws of the control group with the adjustment times of 7±2 times (range, 4-10 times), statistical difference was present ( t=6.99, P<0.001). The surgical time in experimental group (63±12 min) was shorter than that in control group 88±23 min, while effective intraoperative fluoroscopy times in experimental group (9±3 times) was less than that in control group (35±7 times), the difference were both statistically significant ( t=2.69, P=0.016; t=9.22, P<0.001). The intraoperative blood loss was 38±12 ml in the experimental group and 55±26 ml in control group, with no significant difference ( t=1.61, P=0.127). According to Matta's reduction criteria after surgery, the results of experimental group were excellent in 4 cases, good in 2, and fair in 1, while the result of control group were excellent in 5 cases, good in 3, fair in 2, and poor in 1. At the last follow-up, among the patients in experimental group, the Majeed score was 84±11, excellent in 3 cases, good in 2, and fair in 2. In control group, the score was 79±17, with excellent in 5 cases, good in 3, fair in 3. No statistical difference was observed in two groups ( t=0.69, P=0.501). The VAS was 6.4±2.6 preoperatively and 2.4±0.8 postoperatively in the experimental group, while in the control group was 6.9±3.1 preoperatively and 2.7±1.3 postoperatively, the data suggested an improvement in both groups ( t=3.89, P=0.002; t=4.14, P<0.001), while no statistical significant was observed in two groups at last follow-up ( t=0.55, P=0.593). Two cases of experimental group had loosening or withdrawal of the fixation screws in 9 and 12 months, but the fractures healed. Four cases of control group loose fixation screws in 4, 6, 9, and 12 months, two cases underwent revision surgery and other two cases healed. Conclusion:Intelligent visualization system assisted reduction and screw fixation in the treatment of elderly pelvic fragility fractures have the advantages of good reduction, accurate nail placement, less bleeding, less effective fluoroscopy, which improves the safety of surgery.

Objective:To evaluate our self-designed pubic symphysis orthotic compression anatomic plate (PSOCAP) in the treatment of fractures and dislocations around the pubic symphysis.Methods:A retrospective study was conducted to analyze the 16 patients with fracture or dislocation around the pubic symphysis who had been treated by our self-designed PSOCAP at Department of Traumatic Surgery, Center for Orthopaedic Surgery, The Third Hospital Affiliated to Southern Medical University from January 2021 to June 2022. There were 8 males and 8 females with an age of (41±19) years. According to the Tile classification for pelvic fractures, there were 3 cases of type B1, 2 cases of type B3, 1 case of type C1.2, 4 cases of type C1.3, 3 cases of type C2, and 3 cases of type C3. There were 8 cases of pubic symphysis separation and 8 fractures of the pubic ramus (2 ones at Nakatani zone Ⅰ and 6 ones at Nakatani zone Ⅱ). Time from injury to surgery was 16 (11, 53) days, ranging from 4 to 348 days. The fractures or dislocations around the pubic symphysis were exposed by the modified Stoppa approach, reduced with the assistance of PSOCAP and fixated with PSOCAP; the posterior pelvic ring was reduced and fixated by corresponding surgical methods. Recorded were the surgical time, intraoperative bleeding, postoperative quality of fracture reduction, surgical complications, and functional recovery at the last follow-up concerning the pelvic anterior ring.Results:Surgery went on successfully in the 16 patients. Their surgical time was (58±15) min, ranging from 40 to 90 min, and their intraoperative bleeding 85 (63, 150) mL, ranging from 50 to 250 mL. According to the Matta scoring, the fracture reduction was evaluated as excellent in 10 cases, as good in 3 cases and as fair in 3 cases. The (10±3)-month follow-up for the 16 patients revealed complete fracture union for all after (12±2) weeks. According to the Majeed scoring at the last follow-up, the pelvic function was evaluated as excellent in 5 cases, as good in 7 cases, and as fair in 4 cases. No such postoperative complications as fracture displacement or internal fixation failure occurred.Conclusion:Owing to the biplane and integrated structure, our self-designed PSOCAP can help reduce the fractures or dislocations around the pubic symphysis to achieve anatomical reduction and strong internal fixation, leading to good clinical efficacy.

Objective:To explore the surgical methods and treatment effects of adult anterior dislocation of the sacroiliac joint (AADSJ).Methods:A multi-center retrospective case series study was conducted to analyze the clinical data of 25 cases admitted in 5 clinical centers (affiliations of authors in this article) from January 2016 to January 2021. There were 18 males and 7 females, aged 38.8±15.5 years (range, 18-83 years). The AADSJ clinical classification system was formulated based on the radiographic morphology of anterior dislocation of the sacroiliac joint, which includes two types. Type I: complete anterior dislocation of the sacroiliac joint, and displacement of the entire iliac auricular surface to the front of the sacrum. Type II: fracture of the sacroiliac joint combined with anterior dislocation, subdivided into 3 subtypes. Type IIa: iliac fracture involves the anterior 1/3 of the sacroiliac joint, and dislocation of the ilium anterior to the sacrum. Type IIb: iliac fracture involves the posterior 2/3 of the sacroiliac joint, and dislocation of the ilium anterior to the sacrum. Type IIc: iliac fracture involves the posterior 2/3 of the sacroiliac joint, and dislocation of the ilium anteromedial to the sacrum. The reliability and repeatability of the clinical classification, Tile classification and Young-Burgess classification were performed based on the results of two-phase assessments in four observers. The operations were performed by the lateral-rectus approach and the ilioinguinal approach. The operation time and intraoperative bleeding were recorded. Pelvic X-ray and CT scan were rechecked after the operation. The quality of fracture reduction was evaluated according to Matta score. The postoperative functional rehabilitation was evaluated according to the Majeed rehabilitation standard at one-year follow-up.Results:Among 25 cases in this study, there were 3 cases of Type I, 5 cases of Type IIa, 9 cases of Type IIb and 8 cases of Type IIc according to the clinical classification system. The Kappa values of reliability tests for the clinical classification, Tile classification and Young-Burgess classification were 0.681, 0.328 and 0.383, respectively. The Kappa values of repeatability tests for the clinical classification, Tile classification and Young-Burgess classification were 0.690, 0.221 and 0.395, respectively. The reliability and repeatability of the AADSJ clinical classification were significantly better than other classifications. There were 14 cases underwent lateral rectus abdominis approach and 11 cases underwent ilioinguinal approach. The operative time for managing anterior dislocation of the sacroiliac joint was 122.0±50.7 min (range, 65-148 min) through the lateral rectus abdominis approach, and through the ilioinguinal approach was 178.0±49.9 min (range, 110-270 min), with a significant difference ( t=2.76, P=0.011). The amount of intraoperative blood loss through the lateral rectus approach was 680±330 ml (range, 350-2,120 ml), which was significantly less than that through the ilioinguinal approach (1,660±968 ml, 680-3,300 ml), with a significant difference ( t=3.55, P=0.002). The follow-up period was 1-3 years. At one week after surgery, the quality of fracture reduction evaluated by Matta score showed that the excellent and good reduction rate of the lateral-rectus approach was 79% (11/14), and that of the ilioinguinal approach was 73% (11/14), with no statistically significant difference ( P=1.000). At a one-year follow-up, according to Majeed's criteria, the overall excellent and good rate of the lateral-rectus approach was 64% (9/14), which is similar to 64% (7/11) of that of the ilioinguinal approach. No fracture reduction loss or internal fixation loosening failure occurred. Conclusion:The AADSJ clinical classification system can accurately describe the imaging features and clinical manifestations of AADSJ, with high reliability and repeatability. The AADSJ can be treated by the lateral-rectus approach or the ilioinguinal approach, with similar therapeutic effects but the former having less trauma.

Objective:To investigate the surgical method of LC-II screws for fragility fractures of the pelvis (FFP) in the elderly and evaluate its clinical efficacy.Methods:A retrospective analysis was performed on 45 patients with FFPs operated in our department from January 2011 to January 2022. The clinical information was as follows. The FFP classification of pelvic fracture was IIIA in 26 cases and IIIB in 19 cases. Among them, 22 cases were fixed with closed reduction and modified LC-II screws (experimental group), and 23 cases were fixed with open reduction and reconstruction plates (control group). In the experimental group, there were 6 males and 16 females. The age range was 62-90 years, with an average of 73.2±9.2 years. The FFP classification of pelvic fracture was IIIA in 12 cases and IIIB in 10 cases. In the control group, there were 8 males and 15 females. The age range was 60-87 years, with an average of 72.8±6.6 years. FFP classification of pelvic fracture was IIIA in 14 cases and IIIB in 9 cases. After admission, pelvic X-ray and CT scan were performed, and the surgery was prepared. In the experimental group, after closed reduction of the posterior ring, the modified LC-II screw was inserted below the anterior inferior iliac spine (AIIS) toward the sacroiliac joint and penetrated the sacroiliac joint. For combined anterior ring fractures, the INFIX was used for anterior ring fixation. In the control group, the posterior ring was fixed with a reconstruction plate and/or sacroiliac screw after open reduction through the lateral rectus approach (LRA). The clinical efficacy was evaluated between the experimental group and the control group.Results:All 45 patients were successfully operated and followed up for 6 months to 3 years. All the pelvic fractures healed. In the experimental group of 22 cases, the time from injury to operation was 3-9 days, with an average of 5.8±1.9 days; the operation time was 25-70 min, with an average of 42.0±12.9 min. The intraoperative bleeding was 20-40 ml, with an average of 29.1±6.7 ml. According to the X-ray reduction evaluation criteria of Matta, 7 cases were excellent, 11 cases were good and 4 cases were medium, with an excellent and good rate of 81.8%. According to rehabilitation criteria of Majeed, 10 cases were excellent, 6 cases were good and 6 cases were fair, with a total excellent and good rate of 72.7%. At the last follow-up, sacroiliac joint pain was evaluated by VAS score: 0 in 10 cases, <3 in 7 cases, and 4-6 in 5 cases. No internal fixation loosening occurred. In the control group, the time from injury to operation was 5-20 days, with an average of 9.9±3.8 days; the operation time was 50-150 min, with an average of 89.1±29.5 min; the intraoperative bleeding was 220-1 000 ml, with an average of 509.2±214.3 ml. According to the X-ray reduction evaluation criteria of Matta, 16 cases were excellent, 4 cases were good and 3 cases was medium, with an excellent and good rate of 87.0%. According to rehabilitation criteria of Majeed, 12 cases were excellent, 6 cases were good and 7 cases were fair, with a total excellent and good rate of 78.3%. At the last follow-up, sacroiliac joint pain was evaluated by VAS score: 0 in 14 cases, <3 in 6 cases, and 4-6 in 3 cases. In the control group, posterior ring plate loosening was found in 2 cases and anterior ring pubic ramus plate and screw loosening was found in 4 cases, but there was no reduction loss.Conclusion:The modified LC-II screw is theoretically feasible in the treatment of FFP. Preliminary clinical results show good safety and efficacy, providing a new idea for minimally invasive treatment of FFP.

Objective:To investigate the clinical efficacy of integrated acetabular wing-plate in the management of both column fractures with posterior wall involvement via the lateral-rectus approach.Methods:A retrospective case series analysis was performed on 43 patients with both column fractures involved with posterior wall admitted to Third Affiliated Hospital of Southern Medical University from March 2016 to June 2020. There were 35 males and 8 females, aged 19-78 years [(47.3±13.3)years]. The single lateral-rectus approach was used to expose, reduce and fix the fracture using the integrated acetabular wing-plate. Operation time, incision length, intraoperative blood loss and bone healing time were recorded. Quality of fracture reduction was assessed according to the Matta reduction criteria at postoperative 2 days, and hip function by the modified Merle d′Aubigné-Postel score at postoperative 3 months and 12 months. Postoperative complications were observed.Results:All patients were followed up for 12-48 months [(28.1±13.1)months]. Operation duration was 35-150 minutes [(84.6±26.3)minutes], with incision length of 8-12 cm [(9.4±1.0)cm] and intraoperative blood loss of 100-1 200 ml [(200(300, 500) ml]. Bone healing time was 3-6 months [(3.9±0.9)months]. According to Matta reduction criteria,the results were excellent in 32 patients, good in 7 and poor in 4 at postoperative 2 days, with the excellent and good rate of 91%. The modified Merle d′Aubigné-Postel score was 12-18 points [(16.1±1.5)points] at postoperative 3 months, and 13-18 points [(17.3±1.2)points] at postoperative 12 months ( P<0.01). According to modified Merle d′Aubigné-Postel score, the results were excellent in 3 patients, good in 34 and fair in 6 at postoperative 3 months, with the excellent and good rate of 86%; and the results were excellent in 32 patients, good in 9 and fair in 2 at postoperative 12 months, with the excellent and good rate of 95% ( P<0.01). Postoperative complications were incision fat liquefaction and infection in 1 patient, weakness of hip adduction in 5 and screw loosening with traumatic arthritis in 1. There was no sciatic nerve injury or heterotopic ossification. Conclusion:For both column fractures with posterior wall involvement, single lateral-rectus approach combined with integrated acetabular wing-plate has advantages of short operation time, minor trauma, low rate of bleeding and complications, and good hip function recovery, indicating satisfactory clinical effect.

Objective:To compare the clinical efficacy of lateral-rectus approach and ilioinguinal approach in the treatment of Torode-Zieg type IV pelvic fracture in toddlers.Methods:A retrospective cohort study was used to analyze the clinical data of 12 toddlers with Torode-Zieg type IV pelvic fracture admitted to Affiliated Hospital of Youjiang Medical College for Nationalities and Third Affiliated Hospital of Southern Medical University from June 2012 to June 2019. There were 6 males and 6 females, aged 13-36 months [(23.9±7.4)months]. Treatment via ilioinguinal approach was performed for 5 patients (ilioinguinal group), and via lateral-rectus approach for 7 patients (lateral-rectus group). Operation duration, intraoperative blood loss and postoperative complications were compared between the two groups. At the last follow-up, pelvic function was evaluated by Majeed function score, and fracture reduction was evaluated according to Mears-Velyvis radiological evaluation criterion.Results:All patients were followed for 24-72 months [(46.0±18.5)months]. In ilioinguinal group and lateral-rectus group, the operation time was (295.0±95.3)minutes and (165.1±52.2)minutes, respectively ( P<0.05), and the intraoperative blood loss was (190.0±65.2)ml and (225.7±92.0)ml, respectively ( P>0.05). In ilioinguinal group, the development of bilateral iliac wings was asymmetric in 3 patients. In lateral-rectus group, fracture-dislocation of epiphyseal plate together with abnormal development of iliac wing occurred in 1 patient, but had no effects on the function of lower limbs. According to Majeed function score at the last follow-up, the pelvic function in ilioinguinal approach group was rated as excellent in 1 patient, good in 2, fair in 1 and poor in 1, with the excellent and good rate of 60%, while the pelvic function in lateral-rectus group was excellent in 4 patients, good in 1, fair in 2 and poor in none, with the excellent and good rate of 71% ( P>0.05). According to Mears-Velyvis radiological evaluation criterion at the last follow-up, the fracture reduction in ilioinguinal group was rated as satisfied in 3 patients and dissatisfied in 2 patients, with the satisfaction rate of 60%, while the fracture reduction in lateral-rectus group was satisfied in 7 patients and dissatisfied in none, with the satisfaction rate of 100% ( P>0.05). Conclusions:For Torode-Zieg type IV pelvic fracture in toddles, both surgical approaches can complete the reduction and fixation. However, the lateral-rectus approach has shorter operation time and less damage to the epiphyseal structure around the pelvis than the ilioinguinal approach.
