Background: Spinopelvic dissociation (SPD) is difficult to manage and is associated with high mortality and morbidity, including concomitant orthopaedic polytrauma, spine injuries, pelvic ring disruptions, neurological, soft-tissue, and vascular injuries. The purpose of this study is to evaluate the functional and radiological outcomes; health related quality of life and complication rates of patients with traumatic spinopelvic dissociation underwent bilateral triangular osteosynthesis (TOS)., Methods: The study was approved by the medical school's institutional review board (IRB). Prospective data collection of nineteen consecutive cases of traumatic SPD were included in the study from October 2015 to August 2018. Bilateral TOS was performed to manage all patients with SPD. The clinical outcome for fractures was analyzed with Majeed function assessment. Health Related Quality of Life (HRQoL) was assessed with the EQ-6D questionnaire. The reduction quality was evaluated according to Matta criterion. CT scanning was used to verify the fracture union in patients at 24 th weeks postoperatively., Results: There were 12 women and 7 men with an average age of 47.2±8.4 years (range, 17-62 years). The average follow-up time was 25.2±3.7 months (average, 22-45 months). The most common mechanism of injury was falling (57%). According to Majeed functional scoring, the results were excellent in 12 cases, good in 5 cases and fair in 2 cases. The median EQVAS score was 78.9±8.4. 15 patients (78.9%) turned back to their original occupation. Pain and mood disorders mainly influenced patients' present general health status. According to Matta criterion for fracture reduction, the results were excellent in 14 cases, good in 4 cases and fair in 1 case. Complications were noted as wound healing problems (26%), implant loosening (5%) and iatrogenic nerve injury (5%)., Conclusion: Bilateral TOS demonstrates satisfactory functional and radiological outcomes with low complication rates except infection rate in patients with traumatic spinopelvic dissociation. HRQoL is mainly dominated by pain and mood disorders. 78.9% of the patients turned back to their original occupation. Surgeons should be aware of wound healing problems in case of increased muscle mobilization and degloving injuries.Implant removal is required to improve the lumbopelvic mobility., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Ltd.

Introduction: Operative treatment consisting of fracture reduction and fixation, or arthroplasty to permit early patient mobilization, continues to be the treatment of choice for most femoral neck fractures. Options for internal fixation have included a variety of implants; however most recent reports and textbooks cite parallel multiple cancellous screws as the surgical technique of choice., Methods: The study was prospective, randomized and IRB approved. Inclusion criteria included skeletal maturity, closed femoral neck fracture without concomitant fractures or injuries with complete charts and adequate radiographs obtained from the initial injury till the last follow-up. Forty-four patients were enrolled in this study during one-year period at two university centers. 22 were randomized to be treated with full threaded, cannulated compression screws (Acutrak 6/7, ACUMED) (Group 1) and the other 22 with 16mm partial threaded, 6.5mm or 7.3mm cannulated screws (SYNTHES) (Group 2). Three or four screws were used in both groups according to fracture type and surgeon's preference. Data evaluated included surgical time, fluoroscopy time, fracture type, radiological outcome, complications and functional status using the Harris Hip Score., Results: Both groups were comparable in terms of age and gender. There was not a significant difference in terms of surgical time, follow-up period, fracture type, or fluoroscopy time. There were eight complications in Group 1 and two in Group 2 (P=0.049) Time to union was significantly longer in Group 1 (P=0.001). However, Hip Scores were not significantly different in both groups (P=0.20)., Conclusion: When compared with full threaded compression screws, partial-threaded cannulated screws provides a shorter union time and less complication rate while providing equivalent functional results in adult femoral neck fractures., (Copyright © 2015 Elsevier Ltd.

Introduction: The main aim of this retrospective study was to present our experience on scaphoid nonunion treated with vascularised bone graft., Methods: Between 2006 and 2012, 58 patients presenting with symptomatic scaphoid nonunion were eligible to participate in this study. Topography of the nonunion included 29 proximal, 25 waist and 4 distal scaphoid nonunions. Vascularised bone graft from distal dorsal radius was used in all cases which were stabilised with the headless cannulated compression screws. Scapholunate angles, Natrass carpal height ratio were evaluated pre and postoperatively. Range of motion of the affected side was compared to that of the contralateral side after the surgery., Results: Radiographic union was achieved in 50, out of 58 cases with an average time of 9.9 weeks (range, 6-18 weeks). Out of all the non-united cases, four of them were in proximal, three in the waist and one was in distal scaphoid. In nine proximal nonunions treated by 4+5 ECA graft all but one were united. The mean follow up was 21.7 months (12-62 months). The flexion was 91.6%, the extension was 91.5%, the radial deviation was 81.2%, and the ulnar deviation was 89.5% compared to the other side. The grip strength was 93%. Preoperative DASH score was 61.5 diminishing to 28.7 postoperatively. There was no significant change in Natrass carpal height ratio but a slight improvement occurred in scapholunate angles both pre and postoperatively., Conclusion: Vascularised bone graft is a good solution for scaphoid nonunion to enhance the healing rate especially in the presence of avascular necrosis. Proximal pole nonunions, humpback deformity and smoking are important negative factors for scaphoid nonunion despite the use of a vascularised bone graft. A trapezoidal wedge graft is necessary for the volar type nonunions with humpback deformity. 1,2 ICSRA offer an advantage with its proximity to scaphoid in all nonunion locations. Nonetheless, 4+5 ECA graft is also a good solution for proximal nonunions., (Copyright © 2015 Elsevier Ltd. All rights reserved.)

Introduction: Burst fractures of the low lumbar spine constitute approximately one percent of all lumbar fractures. There is still no consensus on the optimal treatment of low lumbar burst factures. We aimed to evaluate the functional and radiographic outcomes of conservative treatment in patients with low lumbar burst fracture., Methods: 15 patients (11 males, 4 females; mean age 32±8) who had low lumbar spine burst fracture treated with a custom-moulded thoracolumbosacral orthosis (TLSO) with a thigh extension were enrolled. The mean follow-up period was 22±6 months. 14 patients were neurologically intact and one had isolated nerve root injury. There were 24% type A fractures and 76% type B fractures according to the Denis classification system. Functional outcomes were evaluated by using Oswestry Disability Index (ODI), Short-Form 36 (SF-36) and Visual Analogue Scale (VAS). Radiographic outcome was analyzed by measuring anterior vertebral height loss, kyphosis angle, amount of canal retropulsion. Functional and radiographic outcomes were reviewed initially and at 1, 3, 6, 12 months, and at the latest follow-up. Functional and radiographic improvements were analyzed statistically., Results: The mean bracing period was 11.9±1.7 weeks. The mean initial ODI, SF-36, and VAS score of the patients was 78.3±9.6, 23.7±8.9, and 8.7±0.7, respectively. The mean ODI, SF-36, and VAS score of the patients at the final follow-up was 26.4±6.5, 68.1±11.2, and 2.8±1.7, respectively. The improvement in functional outcomes was measured to be significant (p<0.05 for ODI, SF-36 and VAS). The mean initial anterior vertebral height loss, kyphosis angle, amount of canal retropulsion was found to be 27.2%±9.6%, -6.8°±3.2°, 37.4%±10.2%, respectively. The mean anterior vertebral height loss, kyphosis angle, and amount of canal retropulsion at the final follow-up was 23.1%±.6.7%, -4.2°±2.4°, 19.6%±7.7%, respectively. Among the radiographic outcomes, only the amount of canal retropulsion improved statistically (p=0.042)., Conclusion: Conservative treatment using a custom-moulded thoracolumbosacral orthosis with a thigh extension is a safe and effective method in patients with low lumbar spine burst fractures and can improve functional and radiographic outcomes., (Copyright © 2015 Elsevier Ltd.
