Far cortical locking constructs for fixation of distal femur fractures in an Asian population: A prospective observational study.

Background: The stiffness of locked plates suppresses healing process, prompting the introduction of far cortical locking to address this issue. This study aimed to demonstrate the clinical efficacy of far cortical locking constructs in treating distal femoral fractures in an Asian population.

Methods: This multicenter prospective observational study was conducted at four university hospitals between February 2018 and February 2021.

Comparative Short-Term Outcomes of Femoral Neck System (FNS) and Cannulated Screw Fixation in Patients with Femoral Neck Fractures: A Multicenter Study.

Background: Femoral neck fractures need to be treated in their early stages with accurate reduction and stable fixation to reduce complications. The authors compared the early radiologic outcomes of femoral neck fractures treated with the recently introduced Femoral Neck System (FNS, Depuy-Synthes) with conventional cannulated screws (CS) in a multicenter design. Furthermore, the factors associated with early failure after FNS were analyzed.

A retrospective cohort study of autogenous iliac strut bone grafting in large bone defects of the lower extremity.

Autogenous iliac bone graft (AIBG) is the treatment of choice for managing bone defects, and favorable results have been reported for bone defects < 5 cm in length. In large bone defects ≥ 5 cm, it is difficult to obtain good results with simple bone grafting, and other management options have drawbacks, such as long immobilization periods and high complication rates. We hypothesized that AIBG in the strut form might show favorable results in large bone defects with minimal complications.

Comparing outcomes of plate augmentation, nail exchange, and nail exchange with plate augmentation in the treatment of atrophic femoral shaft nonunion after intramedullary nailing: a multicenter retrospective study.

Introduction: Intramedullary (IM) nailing is the treatment of choice for femoral shaft fractures, but nonunion rates have been reported to be as high as 12%. Surgical interventions for nonunion involve exchange nailing or plate augmentation. Recently, a combined treatment of exchange nailing and plate augmentation has demonstrated good results, but its comparative effectiveness remains unclear.

Design: Retrospective cohort study.

Setting: Two University Hospitals.

Usefulness of a drill stopper to prevent iatrogenic soft tissue injury in orthopedic surgery.

Objective: This study introduces a novel technique utilizing a drill stopper to limit drill penetration depth and to prevent iatrogenic injuries, specifically neurovascular damage, in orthopedic surgeries. Orthopedic surgeries frequently involve the use of drills, which are essential tools for various procedures. However, improper handling of drills can lead to iatrogenic soft tissue injuries, causing severe consequences such as permanent disability or life-threatening complications.

Reconstruction of a Severe Open Tibiofibular Fracture using an Ipsilateral Vascularized Fractured Fibula with a Thoracodorsal Artery Perforator Free Flap.

The Gustilo IIIB tibiofibular fractures often result in long bone loss and extensive soft tissue defects. Reconstruction of these complex wounds is very challenging, especially when it includes long bone grafts, because the donor site is limited. We describe our experience using a set of chimeric ipsilateral vascularized fibula grafts with a thoracodorsal artery perforator free flap to reconstruct the traumatic tibia defects.

Application of stacked autoencoder for identification of bone fracture.

This study presents a stacked autoencoder (SAE)-based assessment method which is one of the unsupervised learning schemes for the investigation of bone fracture. Relatively accurate health monitoring of bone fracture requires considering physical interactions among tissue, muscle, wave propagation and boundary conditions inside the human body. Furthermore, the investigation of fracture, crack and healing process without state-of-the-art medical devices such as CT, X-ray and MRI systems is challenging.

A modified induced membrane 2-stage technique using a thoracodorsal artery perforator free flap followed by vascularized or non-vascularized free fibular transfer for the treatment of complex bone infection with concomitant severe soft tissue lesion-A case series of 9 cases.

Treatment of post-traumatic complex bone infection is very challenging. The two principal bone reconstruction approaches are the single-stage vascularized bone graft technique and the two-stage induced membrane technique (IMT). Here we introduce a modified 2-stage induced membrane technique (MIMT) for complex long bone infection with a major bone defect and a concomitant severe soft tissue lesion.

Outcomes of Angular Stable Locking System in Femoral Diaphyseal Fractures of Elderly Patients: A Multicenter Comparative Study.

Background: The angular stable locking system (ASLS) was developed to provide additional stability to the distal interlocking screw of the intramedullary (IM) nail. Effects of ASLS on the treatment of femoral diaphyseal fractures in the elderly remain unknown. The aim of this study was to compare radiological outcomes of IM nailing using ASLS screws to IM nails with conventional interlocking screws in elderly patients with femoral shaft fractures.

A multicenter study of factors affecting nonunion by radiographic analysis after intramedullary nailing in segmental femoral shaft fractures.

The factors affecting the outcomes of segmental femoral shaft fractures are currently unknown. We evaluated the outcomes of intramedullary (IM) nail fixation and investigated factors affecting nonunion of femoral shaft segmental fractures. A total of 38 patients who underwent IM nail fixation for femoral shaft segmental fractures (AO/OTA 32C2) at three university hospitals with a minimum 1-year follow-up period were retrospectively reviewed.

Biomechanical comparison of the femoral neck system and the dynamic hip screw in basicervical femoral neck fractures.

The purpose of this study was to compare the fixation stability of proximal fragments and the mechanical characteristics in proximal femur models of basicervical femoral neck fracture fixed by the femoral neck system (FNS) versus the dynamic hip screw. The mean axial stiffness was 234 ± 35 N/mm in the FNS group and 253 ± 42 N/mm in the DHS group, showing no significant difference (p = 0.654).

Mid-term outcomes after the surgical treatment of atypical femoral fractures : minimum three-year follow-up.

Aims: The incidence of atypical femoral fractures (AFFs) continues to increase. However, there are currently few long-term studies on the complications of AFFs and factors affecting them. Therefore, we attempted to investigate the outcomes, complications, and risk factors for complication through mid-term follow-up of more than three years.

Reconstruction of recalcitrant pressure ulcers with latissimus dorsi muscle-splitting free flaps.

Background: Reconstruction of recalcitrant pressure ulcers is very challenging because all available local tissues have been exhausted. Although occasionally suggested as reconstructive options in some reports, free flaps are still not favored for pressure ulcers because of the less available recipient vessels in buttock area and the need for position change. Here, we describe our experience with latissimus dorsi muscle-splitting free flaps harvested in prone position for recalcitrant pressure ulcers.

Experimental study of the effect of the boundary conditions of fractured bone.

Reliable fracture diagnosis monitoring and analyzing low-frequency transverse vibration data can be achieved through an in-depth understanding of the physical interactions between wave propagation and boundary conditions. The present study aims to investigate the effects of the boundary conditions on the low-frequency structural vibrations of bones. Time-frequency domain analysis of transverse vibration signals depending on the boundary conditions of bones is analyzed and investigated.

Delayed Peroneal Neuropathy After Bosworth Fracture Dislocation of the Ankle.

The Bosworth ankle fracture-dislocation is a rare injury and is often irreducible because of an entrapped proximal fragment of the fibula behind the posterior tibial tubercle. Repeated closed reduction or delayed open reduction may result in several complications. Thus, early open reduction and internal fixation enable a better outcome by minimizing soft-tissue damage.

Is Femoral Fracture Healing Really Compromised in Patients with Rheumatoid Arthritis? Comparison Study Between Rheumatoid and Non-rheumatoid Arthritis Patients.

Background: In patients with rheumatoid arthritis (RA), some problems might occur in fracture healing; however, clinical evidence is limited. Therefore, we compared the time to union and complication rate of femoral fractures between RA and non-RA patients.

Materials And Methods: This study included 42 RA patients who underwent osteosynthesis for femoral trochanter or shaft fracture.
