Notch sensitivity may compromise titanium-alloy plate fatigue strength. However, no studies providing head-to-head comparisons of stainless-steel or titanium-alloy locking plates exist.Custom-designed identically structured locking plates were made from stainless steel (F138 and F1314) or titanium alloy. Three screw-hole designs were compared: threaded screw-holes with angle edges (type I); threaded...
The objective of this study was to identify indications and predictors for subsequent surgeries in the same hip and to evaluate life expectancy following screw fixation of undisplaced femoral neck fractures (FNF). The study further aimed to determine the necessary follow-up time for future studies aiming to evaluate the treatment of such fractures.This is a single-center retrospective cohort study...
To analyze knowledge of the anatomic location of the piriform fossa using a questionnaire with anatomic figures.Participants taking AO Trauma Brasil courses were requested to complete a questionnaire containing a photograph of the superior surface and a photograph of the lateral surface of the femur and answer a question asking which of four numbered points corresponded to the piriform fossa.Just...
Syndesmotic disruption may be difficult to reduce and fix, and malreduction is associated with inferior outcomes. Intraoperative computed tomography (CT) can provide accurate assessment of syndesmotic reduction. We hypothesized that three-dimensional (3-D) computer-assisted orthopaedic surgery (CAOS) with navigation of syndesmotic reduction could avoid malreduction. Our goal was to assess feasibility...
The goals of this study were to identify the proportion of early adolescents in southern South America who were injured in the past year, to identify risk behaviours and other exposures associated with injuries, and to evaluate the most common types and causes of injury in this population.We used complex samples analysis to examine cross-sectional data from more than 35,000 students from all four...
Temporary external fixators are often used to stabilize fractures when definitive fracture surgery must be delayed. Sometimes, external fixators are left in place during repeat operations, including definitive internal fixation of tibial pilon and tibial plateau fractures. It is unknown how well current surgical preparation sterilizes these devices, which become part of the surgical field. Our hypothesis...
Free tissue transfers are a highly reliable procedure routinely performed for reconstruction of a wide range of defects. Main complication in free flap surgery is usually venous thrombosis. Many technical controversies exist regarding the technical details of the microvascular anastomosis in order to prevent occurrence of thrombosis and optimize outcomes. We therefore evaluated our results regarding...
Compromised bone quality and the need for early mobilization continue to lead to implant failure in elderly patients with distal femoral fractures. The cement augmentation of screws might facilitate improving implant anchorage. The aim of this study was to analyse the impact of cement augmentation of the condylar screws on implant fixation in a human cadaveric bone model.Ten pairs of osteoporotic...
Osteotomy and internal fixation are usually the most effective way to treat the malunion of lateral tibial plateau fractures, and the accuracy of the osteotomy is still a challenge for surgeons. This is a report of a series of prospectively study of osteotomy treatment for the malunion of lateral plateau fractures with the aid of 3D printing technology.A total of 7 patients with malunion of lateral...
Antibiotic-impregnated cement nails are used to treat postoperative deep infections after primary intramedullary nail insertion for the treatment of tibial fractures. Few data exist regarding the efficacy of this treatment strategy. We hypothesized that such treatment with antibiotic nails results in a high rate of infection clearance at intermediate follow-up.We conducted a retrospective review at...
Proximal plate fixation in periprosthetic femur fractures can be improved by plate anchorage in the greater trochanter (lateral tension band principle) or bicortical locking screw placement beside the prosthesis stem in an embracement configuration. Both concepts were compared in a biomechanical test using a femoral hook plate (hook) or a locking attachment plate (LAP).After bone mineral density (BMD)...
Injuries sustained to the hand and wrist are common, accounting for 20% of all emergency presentations. The economic burden of these injuries, comprised of direct (medical expenses incurred), indirect (value of lost productivity) and intangible costs, can be extensive and rise sharply with the increase of severity.This paper systematically reviews cost-of-illness studies and health economic evaluations...
Bone defects remain a challenge for patients and orthopaedic surgeons. Autologous transfer of cancellous bone grafts remains the standard of care. However, in recent years various osteoinductive substitute materials, such as platelet rich plasma (PRP) and hyperbaric oxygen therapy (HBO) have been shown to improve bone healing. This study evaluates the effects of a combined application of PRP and HBO...
Minimally invasive plate osteosynthesis (MIPO) using locking plates has been used in distal femur fractures, but various problems, such as nonunion, malalignment, and implant failure, have been reported. Simple fractures sometimes have poorer outcomes than complex fractures. We studied elderly patients with simple fracture patterns who underwent open reduction followed by placement of a single positional...
To evaluate the ability of orthopaedic trauma subspecialists to predict early bony union in femoral and tibia shaft fractures.Eight orthopaedic trauma subspecialists prospectively predicted the probability of bony union at 6 and 12 weeks post-operatively for an aggregate of 48 femoral and tibial shaft fractures treated at a Level 1 trauma centre. An additional orthopaedic trauma subspecialist was...
After major upper extremity traumatic amputation, replantation is attempted based upon the assumption that outcomes for a replanted limb exceed those for revision amputation with prosthetic rehabilitation. While some reports have examined functional differences between these patients, it is increasingly apparent that patient perceptions are also critical determinants of success. Currently, little...
A focus on what is important to patients has been recognized as an essential pillar in care to ensure safe patient care that focuses on outcomes identified as important by patients. Despite this, asking trauma patients and their families what they consider should be the priorities of care and recovery has been neglected.Adult trauma patients admitted to two centers in Australia for ≥24h for the treatment...
