Abstract Background The supracondylar humerus fractures are the most common fracture in children’s elbows. Generally, close reduction and percutaneous pinning can provide satisfactory outcomes after adequate reduction. Baumann angle is commonly used to evaluate reduction quality, however, it may fail to assess reduction well when the elbow is in flexion and/or when the patient is young. We conducted this study to evaluate the potential value of the humerus trochlear angle (HTa) for the reduction evaluation and compare it with the Baumann angle. Methods We retrospectively reviewed supracondylar humerus fractures in our trauma center from 2016 to 2019. Patients were grouped as followed: in the HTa group, an arthrogram was used to evaluate the HTa angle and reduction (HTa, defined by the intersection of the axis of the humerus shaft and the tangent of the articular surface of the trochlear); In the Baumann group, the Baumann angle was used to assess the reduction. Baumann angle ratio (BA of injured side/BA of contralateral side) was calculated to evaluate the reduction quality between groups. Flynn’s grading criteria were utilized to evaluate both function and cosmetic outcomes in two groups during the follow-up. Operation time, fluoroscopy shots, complications and Flynn’s grading scores were compared between groups. Results A total of 57 patients with an average age of 4.62 years and follow-up duration of 21.49 ± 5.40 months were included in the analysis. The gender and age distributions were similar in the two groups. Fluoroscopy shots in the HTa group were significantly less than in Baumann group (16.17 ± 0.73 vs. 21.85 ± 0.78, p < 0.0001), and operation time were also less in HTa group (45.78 ± 1.96 min vs. 62.21 ± 1.58 min, p < 0.0001). Baumann ratio showed no significant difference between the two groups (1.002 ± 0.023 in the Baumann group and 1.01 ± 0.023 in HTa group, p < 0.0001). Length of hospitalization, complications, and Flynn’s grading scores were similar between groups. The HTa angle was positively correlated with Baumann angle in the HTa group (R-value is 0.71 and P = 0.0002). Conclusions There was no significant difference in reduction quality and Flynn’s scores between HTa and Baumann groups. Furthermore, HTa was associated with shorter operation time and less radiation exposure in this investigation. Therefore, HTa may be a convenient and reliable parameter that could guide the reduction of supracondylar humerus fractures, especially for young children.

Objective To assess the outcomes of traditional three-dimensional (3D) printing technology (TPT) versus mirror 3D printing technology (MTT) in treating isolated acetabular fractures (IAFs). Methods Consecutive patients with an IAF treated by either TPT or MTT at our tertiary medical centre from 2012 to 2018 were retrospectively reviewed. Follow-up was performed 1, 3, 6, and 12 months postoperatively and annually thereafter. The primary outcome was the Harris hip score (HHS), and the secondary outcomes were major intraoperative variables and key orthopaedic complications. Results One hundred fourteen eligible patients (114 hips) with an IAF (TPT, n = 56; MTT, n = 58) were evaluated. The median follow-up was 25 months (range, 21–28 months). At the last follow-up, the mean HHS was 82.46 ±14.70 for TPT and 86.30 ± 13.26 for MTT with a statistically significant difference. Significant differences were also detected in the major intraoperative variables (operation time, intraoperative blood loss, number of fluoroscopic screenings, and anatomical reduction number) and the major orthopaedic complications (loosening, implant failure, and heterotopic ossification). Conclusion Compared with TPT, MTT tends to produce accurate IAF reduction and may result in better intraoperative variables and a lower rate of major orthopaedic complications.

Objective: The aim of this study is compare the outcomes among three different approaches (lateral approach, medial approach and posterior approach) for supracondylar humerus fractures in children. Study Design: Retrospective cohort study Place and Duration: The study was conducted at Orthopedics department of Ayub Teaching Hospital, Abbottabad for duration of one year from January 2020 to December 2020. Methods: There were one hundred and thirty five children had supracondylar humerus fracture were presented. Patients were aged between 3-12 years. Informed written consent was taken from authorities for detailed demographics age, sex, cause of fracture and side of fracture. Patients were categorized into three equal groups, group A had 45 patients and received lateral approach, group B had 45 patients and received medial approach and group C received posterior approach with 45 cases. Shaft Condylar Angle (SCA) and Baumann angle were used to analyze the radiological result. All children were assessed using Flynn's criteria for functional outcomes, and the results were divided into Excellent, Good, Fair and Poor. Post-operative outcomes among all the three groups were calculated and compared. SPSS 23.0 version was used to analyze complete data. Results: There were 90 (66.7%) males (30 in each group and 45 (33.3%) females (15 in each group). In group A mean age was 6.88±5.45 years, mean age in group B was 7.11±5.33 years and in group C mean age was 7.17±5.66 years. Sports 85 (62.9%) was the most common cause of fracture followed by traffic accidents 30 (22.2%) and the rest were 20 (14.8%) fall from the height. According to radiological outcomes, Mean shaft condylar Angle in group A was 41.5±6.3, in group B was 41.8±1.9 and in group C was 40.1±3.8 respectively (P>0.05). Mean Bauman angle in group A was 18.8±6.11, group B was 19.4±7.5 and in group C 20.4±5.3 with (P>0.05). According to Flynn’s criteria, excellent outcomes were observed in 33 (73.3%) in LA group, 24 (53.3%) in MA group and 22 (48.9%) in PA group, good results were observed in 11(24.4%), 19 (42.2%) and 21 (46.7%), fair outcomes in 1 (2.2%), 2 (4.4%) and 2 (4.4%). Conclusion: As a result of this research, we have concluded that the lateral technique for supracondylar fractures is superior to the medial or posterior approaches in terms of radiological and functional results. However, there was no statistically significant difference between the three groups. Keywords: Supracondylar fractures, Flynn’s criteria, Functional outcome, Open reduction

Abstract PurposeTo compare the efficacy and safety of percutaneous short-segment pedicle screws fixation (PPSF) with or without intermediate screws (IS) for the treatment of thoracolumbar compression fractures.MethodsFrom January 2016 to March 2019, a retrospective study of 38 patients with thoracolumbar compression fractures conducted. The patients were divided into a 4-screw group (without IS) and a 6-screw group (with IS) according to whether pedicle screws were placed in the fractured vertebrae. Combined positional reduction effects with the technique of pre-contoured lordotic rods were used to reduce the fracture by lengthening the anterior column of the fractured vertebrae. The posterior structure of the fractured vertebrae was undertaken as the fulcrum point for both groups. The operation time, intra-operative blood loss, visual analogue scale (VAS), anterior vertebral body height (AVBH), segment kyphosis（SK）before and after operation and complications were recorded.ResultsAlthough the operation time and blood loss in the 6-screw group were higher than in the 4-screw group, difference was not significant (P＞0.05). There was no significant difference in VAS, AVBH and SK between the two groups (P＞0.05). Nevertheless, these results were significant differences between the preoperative and the immediate postoperative, between preoperative and follow-up groups (P < 0.001). No neurologic injury was observed in either groups. ConclusionsIn the treatment of thoracolumbar compression fractures, percutaneous short-segment pedicle screws fixation without intermediate screws in the 4-screw construct may obtain the same clinical effect as that in the 6-screw construct.

Abstract Background: Tibial shaft fractures are routinely managed with intramedullary nailing (IMN). An increasingly accepted technique is the suprapatellar (SP) approach. The purpose of this study was to compare the clinical and functional outcomes of knee joint after tibia IMN through an suprapatellar (SP) or traditional infrapatellar (IP) approach. Methods: Retrospective analysis was performed in patients with tibial shaft fractures that were treated with IMN through a SP or IP approach between 01/01/2014 and 31/12/2016. The clinical and functional outcomes of the knee were assessed with the Hospital for Special Surgery (HSS) Knee Score. Secondary outcomes included the operation time and intraoperative blood loss. Results: A total of 50 patients/fractures (26 IP and 24 SP) with a minimum follow-up of 15 months were evaluated. All fractures were OTA 42. No significant differences were found between the two groups in age, gender, side of fractures, operation time, intra-operative blood loss, and follow-up time. No significant difference was seen in HSS score ( P = 0.62) between them. Sub analysis of all the HSS components scores revealed no significant differences between pain ( P = 0.57), the stand and walk ( P = 0.54), the need for walking stick ( P = 0.60) and extension lag ( P = 0.60). The other HSS components showed full scores (IP 10 vs. SP 10) in both approaches, including muscle force, flexion deformity and stability components. The range of motion (ROM) component score was superior in the IP group ( P = 0.04) suggesting a higher ROM. Conclusions: Both SP and IP approach results in equivalent overall HSS knee scores. However, for the HSS component, the IP approach was superior to SP approach regarding the ROM.

Abstract Objective To explore the feasibility of laparoscopic partial nephrectomy(LPN) in the treatment of renal hilar tumors. Methods Clinical data of 290 patients undergoing laparoscopic partial nephrectomy from January 2013 to August 2019 were retrospectively analyzed, including 27 patients with renal hilar tumors and 263 patients with non-hilar renal tumors. Perioperative data and follow-up results were compared between the two groups. Results Tumor size in Group A is smaller(2.97±0.88 vs 3.55±1.46,p<0.05), R.E.N.A.L. nephrometry score of Group A is higher(8.4±1.3 vs 6.5±1.7,p<0.01).The operation time, WIT and intraoperative blood loss in the Group A were slightly higher, but with no statistical difference (p>0.05). There was no significant difference between the two groups in intraoperative ultrasound rate, collection system repair rate, drainage time,postoperative hospital stay, and eGFR changes (p>0.05).The median follow-up period was 40 months. One patient with postoperative pathologic report of angiomyolipoma was found tumor recurrence and was currently undergoing regular reexamination. Conclusion Three-dimensional laparoscopic partial nephrectomy for renal hilar tumors is safe and feasible after detailed preoperative evaluation of the tumor and selection of appropriate surgical strategies.

Introduction: Displaced supracondylar fracture in children is a challenging injury that may result in impaired functional and cosmetic outcome if not well-treated. Utilization of Closed Reduction and Percutaneus Pinning (CRPP) increased for this pathology, some authors believe ORIF results better anatomical reduction and lower rate of loss of reduction. Study aims to compare CRPP and ORIF for pediatric supracondylar humerus fracture. Method: Systematic review was conducted based on PRISMA guideline. Inclusion criteria were age <18 years old, comparing CRPP and ORIF for Supracondylar Humerus Fractures Gartland Type II, II.Studies of one surgical technique, Gartland type I, case reports were excluded. For meta-analysis, 6 studies were included and fixed effect model used to pool the result. In each study, mean difference (MD) with 95% confidence interval (CI) was calculated for dichotomous outcomes using Review Manager. Result: Total of 252 patients aged 0-15 years old were included. CRPP more often performed than ORIF. Satisfactory outcomes measured by Flynn’s criteria were achieved in 87.74% in CRPP and 86.73% in ORIF patient group, indicating significant difference (Heterogeneity, I2 = 23%; WMD, 1.26; 0.58 to 2.73; P =0.56). Conclusion: Current systematic review and meta-analysis suggest that for displaced supracondylar humerus fractures, ORIF offers a comparable functional and cosmetic outcome compared to CRPP.

Background and objectives: Supracondylar humerus fractures are common in children andcan be surgically treated. However, the general surgical procedures involving reduction andfixation might lead to reduction loss, failure to direct the Kirschner (K)-wire toward the desiredposition, prolonged surgery, or chondral damage. This study aimed to show that temporaryfixation of closed reduction with a fabric adhesive bandage in pediatric supracondylar humerusfractures could maintain reduction so that surgical treatment can be easily performed by a singlephysician. Materials and Methods: Forty-six patients with Gartland type 3 supracondylar humerusfractures who underwent surgical treatment between May 2017 and June 2018 were retrospectivelyevaluated. Fluoroscopy-guided reduction and fixation were performed from the distal third of theforearm to the proximal third of the humerus using a fabric adhesive bandage. Two crossed pinswere applied on the fracture line by first inserting a lateral-entry K-wire and then inserting anotherK-wire close to the anterior aspect of the medial epicondyle and diverging from the ulnar nervetunnel. A tourniquet was not applied in any patient and no patients required open reduction.Results: The study included 32 boys (69.6%) and 14 girls (30.4%) (mean age, 7.1; range, 2–16 years).The mean hospital stay and follow-up duration were 4.3 ± 3.9 days and 48.1 ± 14.3 weeks,respectively. Heterotopic ossification was detected in one patient, and ulnar nerve neuropraxia wasdetected in another patient. Functional (according to Flynn criteria) and cosmetic outcomes wereexcellent in 95.6%, moderate in 2.2%, and poor in 2.2% of patients. The mean duration of fixation ofthe closed reduction with a fabric adhesive bandage was 8.1 ± 3.9 min, and the mean duration ofpinning was 7.9 ± 1.4 min. Conclusions: Temporary preoperative fixation of supracondylar humerusfractures that require surgical treatment with a fabric adhesive bandage may be significantlyconvenient in practice.
