简介：AbstractPurpose:Triceps tendon avulsion (TTA) is an uncommon injury, and there are no classifications or treatment guidelines available. This study aims to describe a clinicoradiological classification and treatment algorithm for traumatic TTA in adults. The functional outcome of surgical repair has been evaluated too.Methods:A retrospective analysis of adult patients with traumatic TTA treated in our institution between January 2012 and December 2017 was done. We only included complete TTA injuries. Children below 15 years, with open injuries, associated fractures, or partial TTA were excluded. The data were obtained from hospital records. The intraoperative findings were correlated with the clinicoradiological presentation for classifying TTA. The functional outcome was analyzed using the Mayo Elbow Performance index and Hospital for Special Surgery elbow score. ANOVA test was used to assess the statistical significance.Results:There were 15 patients included, 11 males and 4 females. The mean age was (31.5 ± 9.15) years, and the mean follow-up was (22.4 ± 8.4) months. Fall on outstretched hand was the mode of injury. In 6 patients, diagnosis was missed on the initial visit. TTA were classified as Type I: palpable soft-tissue defect without bony mass; Type II: palpable soft-tissue defect with a wafer-thin/comminuted bony fragment on X-ray; Type III: palpable soft-tissue defect with a bony mass and a large bony fragment on X-ray without extension to the articular surface; and Type IV: an olecranon fracture with less than 25% of the articular surface. An algorithm for treatment was recommended, i.e. transosseous suture repair/suture anchor for Type I, transosseous suture repair for Type II, and tension band wiring or steel wire sutures for Types III and IV. All the patients achieved good to excellent outcome: the mean Mayo Elbow Performance index was 100 and Hospital for Special Surgery score was 98.26 ± 2.60 on final follow-up.Conclusion:Our clinicoradiological classification and treatment algorithm for TTAs is simple. Surgical treatment results in excellent functions of the elbow. Since it is a single-center study involving a very small number of cases, a multicenter study with a larger number of patients is required for external validation of our classification and treatment recommendations.

简介：AbstractFractures of the acetabulum in elderly patients were often caused by low energy trauma. Fractures involving anterior column are more common and often associated with impaction and comminution. Osteoporosis further complicates the management. Percutaneous fracture fixation has low morbidity but it is a technically demanding procedure. Open reduction and fracture fixation is done with or without simultaneous total hip replacement. Delayed total hip replacement is considered in posttraumatic arthritis patients. Patients with minimal displaced fractures, associated both-column fractures with secondary congruence of joint and patients who are medically unfit for surgery can be managed non-operatively. Whatever be the method of management, these elderly patients should be mobilised as early as possible.

简介：AbstractMandibular condylar fractures are among the most common facial fractures and some of the most difficult to manage. Opinions about the management of mandibular condylar fractures differ among surgeons. With the implementation of new technology, an increased understanding of fracture management, and better functional and morphological outcomes reported in the literature, open reduction and internal fixation is becoming many surgeons’ preferred choice for the treatment of condylar fractures. Because surgical treatment of such fractures is complex, certain factors must be considered to achieve satisfactory outcomes. In this article, we summarise six key points in the management of mandibular condylar fractures: virtual evaluation of condylar fracture, a suitable surgical approach, good reduction, stable internal fixation, repair of the articular disc, and restoration of the mandibular arch width. We believe that these points will help to improve the prognosis of mandibular condyle fractures.

简介：AbstractPurpose:Pelvic fracture evaluation with abdominopelvic computed tomography (CT) and formal CT cystography for rule out of urine bladder injury have been commonly employed in pediatric trauma patients. The additional delayed imaging required to obtain optimal CT cystography is, however, associated with increased doses of ionizing radiation to pelvic organs and represent a significant risk in the pediatric population for future carcinogenic risk. We hypothesized that avoidance of routine CT cystography among pediatric pelvic fracture victims would not result in an appreciable rate of missed bladder injuries and would aid in mitigating the radiation exposure risk associated with these additional images.Methods:A retrospective cohort study involving blunt trauma pelvic fractures among pediatric trauma patients (age<14) between the years 1997 and 2016 was conducted utilizing the Israeli National Trauma Registry. Statistical analysis was performed using SAS statistical software version 9.4 via the tests of Chisquare test and two-sided Fisher's exact test. A p value of less than 0.05 was considered statistically significant.Results:A total of 1072 children were identified from the registry for inclusion. Mean age of patients was 7.7 years (range 0-14) and 713 (66.5%) were male. Overall mortality in this population was 4.1% (44/1072). Only 2.1% (23) of pediatric patients with pelvic fractures had bladder injury identified, with just 9 children having intraperitoneal bladder rupture (0.8% of all the patients).Conclusion:The vast majority of blunt pediatric trauma victims with pelvic fractures do not have urine bladder injuries. Based on our study results we do not recommend the routine utilization of CT cystography in this unique population.

简介：AbstractPurpose:To assess the clinical efficacy of converting partial articular supraspinatus tendon avulsion (PASTA) lesions to full-thickness tears through a small local incision of the bursal-side supraspinatus tendon followed by repair.Methods:We retrospectively analyzed 41 patients with Ellman grade 3 PASTA lesions and an average age of (54.7 ± 11.4) years from March 2013 to July 2017. Patients without regular conservative treatment and concomitant with other shoulder pathologies or previous shoulder surgery were excluded from the study. The tears were confirmed via arthroscopy, and a polydioxanone suture was placed to indicate the position of each tear. A small incision of approximately 6 mm was made using a plasma scalpel on the bursal-side supraspinatus tendon around the positioned suture to convert the partial tear into a full-thickness tear. The torn rotator cuff was sutured through the full thickness using a suture passer after inserting a 4.5-mm double-loaded suture anchor. Data were analyzed using a paired Student’s t-test with statistical significance defined as p <0.05.Results:At the final follow-up of 2 years, the pain-free shoulder joint range of motion and visual analog scale score were significantly improved compared to those before surgery (p < 0.001). The postoperative American Shoulder and Elbow Surgeons shoulder score was (90.6 ± 6.2), which was significantly higher than the preoperative score of (47.9 ± 8.3) (p < 0.001). The University of California at Los Angeles shoulder rating scale score increased from (14.7 ± 4.1) prior to surgery to (32.6 ± 3.4) points after surgery (p < 0.001). No patient had joint stiffness.Conclusion:This modified tear completion repair, by conversion to full-thickness tears through a small incision, has less damage to the supraspinatus tendon on the side of the bursa compared to traditional tear completion repair in the treatment of PASTA lesions. This surgical method is a simple and effective treatment that can effectively alleviate pain and improve shoulder joint function.

简介：AbstractPurpose:Hemodynamically unstable patients with pelvic fractures still represent a challenge to trauma surgeons and have a very high mortality. This study was designed to explore the effect of the interventions of direct preperitoneal pelvic packing for the hemodynamically unstable pelvic fractures.Methods:This retrospective study enrolled 67 cases of severe pelvic fractures with unstable hemodynamics from October 2011 to December 2019. All patients presented in our emergency center and received preperitoneal pelvic packing were included in this study. The indication was persistent systolic blood pressure ≤90 mmHg during initial resuscitation and after transfusion of two units of red blood cells. Patients with hemodynamic stability who need no preperitoneal pelvic packing to control bleeding were excluded. Their demographic characteristics, clinical features, laboratory results, therapeutic interventions, adverse events, and prognostic outcomes were collected from digital information system of electronic medical records. Statistics were described as mean ± standard deviation or medium and analyzed using pair sample t-test or Mann-Whitney U-test.Results:The patients’ average age was 41.6 years, ranging from 10 to 88 years. Among them, 45 cases were male (67.2%) and 22 cases were female (32.8%). Significant difference was found regarding the systolic blood pressure (mmHg) in the emergency department (78.4 ± 13.9) and after preperitoneal pelvic packing in the surgery intensive care unit (100.1 ± 17.6) (p < 0.05). Simultaneously, the arterial base deficit (mmol/L) were significantly lower in the surgery intensive care unit (median -6, interquartile range -8 to -2) than in the emergency department (median -10, interquartile range -14 to -8) (p < 0.05). After preperitoneal pelvic packing, 15 patients (22.4%) underwent pelvic angiography for persistent hypotension or suspected ongoing haemorrhage. The overall mortality rate was 29.5% (20 of 67).Conclusions:Preperitoneal pelvic packing, as a useful surgical technique, is less invasive and can be very efficient in early intra-pelvic bleed control.
