Background: Although most studies focused on the alignment or union of the tibia in same-level distal third tibiofibular fractures, the outcome of a concomitant fibular fracture is generally regarded as being of secondary importance in the literature. This study aimed to assess the outcomes of fibular fractures in same-level distal third tibiofibular fractures.

Methods: In this retrospective study, we enrolled 111 patients with same-level distal third tibiofibular fractures treated at our institute between January 2016 and August 2020.

Background: Plate fixation for atypical femoral fractures has shown high failure rates compared to intramedullary nail fixation. The aim of this study was to evaluate the radiological results of patients treated with a plate and screws for atypical fractures of the femoral diaphysis.

Methods: This study was conducted retrospectively on 16 patients who had undergone internal fixation using plates for treatment of atypical femoral complete fractures from 2007 to 2015.

Backgroud: The aim of this study was to evaluate results of osteoperiosteal decortication and autogenous cancellous bone graft combined with a bridge plating technique in atrophic and oligotrophic femoral and tibial diaphyseal nonunion.

Methods: We retrospectively reviewed 31 patients with atrophic or oligotrophic femoral and tibial diaphyseal nonunion treated with osteoperiosteal decortication and autogenous cancellous bone graft between January 2008 and December 2018. Patients with hypertrophic nonunion, infected nonunion, and nonunion treated with autogenous cancellous bone graft alone were excluded.

Background: Displaced anterior column fractures have increasingly been treated surgically by the ilioinguinal approach and fixation with lag screws and a buttress plate on the pelvic brim. However, a major disadvantage of the ilioinguinal approach is possible damage to the neurovascular bundle and the lymphatic structures in the intermediate part of the approach. This study aims to present a novel surgical technique of the less invasive anterior iliac approach and compression osteosynthesis for high anterior column fractures of the acetabulum.

Introduction: The purpose of the study was to determine the surgical outcomes of intramedullary nailing in diaphyseal atypical femoral fractures (AFFs) and to evaluate the clinical outcomes of nail entry modification technique.

Materials And Methods: We retrospectively reviewed diaphyseal AFFs treated with IMN at nine institutions. In total, 82 patients were included.

Introduction: Many studies have tried to determine the characteristics of atypical femoral fractures (AFFs) through age-, sex-, and ethnicity-matched comparison with non-AFFs. However, we hypothesized that diaphyseal AFFs would have characteristics different from those of subtrochanteric AFFs. The aim of this study was to evaluate the clinical features of diaphyseal/subtrochanteric AFFs and determine the factors related to fracture location.

Purpose: To verify the practical correlation between the topographical features of the femur neck base and the ideal entry point by analyzing three-dimensional (3D) models virtually implanted with an antegrade femoral nail.

Materials And Methods: A total of 103 cadaveric femurs (50 males and 53 females) were enrolled. Specimens underwent continuous 1.

Purpose: The purpose of this study was to evaluate whether we have to stop the antiplatelet agents prior to hemiarthroplasty surgery in patients with displaced femur neck fractures to reduce postoperative complications.

Materials And Methods: We enrolled forty-three patients with displaced femur neck fractures who were treated by bipolar hemiarthroplasty and were taking antiplatelet agents. Group I included 21 patients who discontinued antiplatelet agents and had delayed operations at an average 5.

The goal of this study was to determine the incidence of avascular necrosis of the femoral head (AVNFH) after intramedullary nailing of femoral shaft fractures and to identify risk factors for developing AVNFH.We retrospectively reviewed all patients with femoral shaft fractures treated with antegrade intramedullary nailing at 10 institutions. Among the 703 patients enrolled, 161 patients were excluded leaving 542 patients in the study.

Background: The purpose of the current study was to investigate the incidence of preoperative deep vein thrombosis (DVT) after hip fractures in Korea.

Methods: In this prospective study, we enrolled 152 Korean geriatric patients who had suffered hip fractures due to a simple fall and were hospitalized between January 2013 and December 2013. There were 52 male and 100 female patients, and their mean age was 78.

Femoroacetabular impingement and dysplatic hip joint is well known cause of osteoarthritis. In these diseases, labral tear and subsequent cartilage damage is thought to be main pathophysiology of development of osteoarthritis. If there are no known bony abnormalities, we called it as idiopathic osteoarthritis.

Objectives: To compare the clinical and radiologic results of conventional open plating (COP) and minimally invasive plate osteosynthesis (MIPO) in the treatment of noncomminuted humeral shaft fractures.

Design: Randomized prospective study.

Setting: Five level 1 trauma centers.

Background: Femoral fractures in adolescents usually need operative treatment, but the optimal method is unclear. The purpose of this study is to compare intramedullary nailing (IN) and submuscular plating (SP) in adolescent femoral fractures.

Materials And Methods: We performed the prospective, comparison study of IN and SP in adolescent femoral shaft fractures at a mean age of 13.

Objective: The objective of this study was to establish the relative fixation strengths of a locking plate, a dynamic condylar screw (DCS) plate, and a long proximal femoral nail (PFN).

Methods: The study involved three groups of composite large femoral synthetic bones of five specimens per group; plating using a locking compression plate-distal femur (LCP-DF), plating using a DCS plate, and nailing using a long PFN. A gap osteotomy model was used to simulate a comminuted subtrochanteric femur fracture.

Background: Intramedullary nailing is a mainstay in the treatment of subtrochanteric femoral fractures. But nailing is often unsuitable for difficult fracture patterns with comminution or when the medullary canal is narrow. The purpose of this study was to clarify the efficacy of minimally invasive plate osteosynthesis (MIPO) with locking compression plate in the treatment of subtrochanteric fractures.
