We evaluated both the outcome of using a locking plate as a definitive external fixator for treating open tibial fractures and, using finite element analysis, the biomechanical performance of external and internal metaphyseal locked plates in treating proximal tibial fractures. Eight open tibial patients were treated using a metaphyseal locked plate as a low-profile definitive external fixator. Then, finite element models of internal (IPF) as well as two different external plate fixations (EPFs) for proximal tibial fractures were reconstructed. The offset distances from the bone surface to the EPFs were 6 cm and 10 cm. Both axial stiffness and angular stiffness were calculated to evaluate the biomechanical performance of these three models. The mean follow-up period was 31 months (range, 18-43 months). All the fractures united and the mean bone healing time was 37.5 weeks (range, 20-52 weeks). All patients had excellent or good functional results and were walking freely at the final follow-up. The finite element finding revealed that axial stiffness and angular stiffness decreased as the offset distance from the bone surface increased. Compared to the IPF models, in the two EPF models, axial stiffness decreased by 84-94%, whereas the angular stiffness decreased by 12-21%. The locking plate used as a definitive external fixator provided a high rate of union. While the locking plate is not totally rigid, it is clinically stable and may be advisable for stiffness reduction of plating constructs, thus promoting fracture healing by callus formation. Our patients experienced a comfortable clinical course, excellent knee and ankle joint motion, satisfactory functional results and an acceptable complication rate.

Background: Length unstable femoral shaft fractures in school-aged children usually demand surgical treatment, but the optimal choice remains controversial, especially in overweight adolescents. This study aimed to compare the clinical results of locking compression plates (LCP) and elastic stable intramedullary nails (ESIN) combined with temporary external fixator (TEF) in school-aged children weighing over 50 kg.
Methods: Between January 2010 and January 2018, children over 50 kg with length unstable femoral shaft fracture treated with ESIN & EF in the authors' institute were included in this study.

Introduction: Aseptic recalcitrant nonunion (ARNU) of the femur and tibia is an entity in which the absence of bony union, misalignment, and limb length discrepancies (LLD) coexist. Currently, the management of these cases lacks consensus. This study aimed to describe the bone union rate and deformity correction outcomes in patients with ARNU of the femur or tibia treated with the Induced Membrane Technique (IMT).

Background: Posterolateral tibial plateau fractures pose significant challenges for orthopedic surgeons due to the anatomical risks associated with the posterolateral approach. Despite numerous surgical techniques available, there lacks a consensus on the optimal approach.
Methods: Articular line incision approach was employed on 12 patients suffering from posterolateral tibial plateau fractures.

Objective: This study aimed to report the clinical, radiographic, and computed tomography results of supracutaneous locking plate (SLP) application in radial-ulnar and tibial fractures.
Study Design: In this clinical prospective study, cats and dogs with nonarticular radial, ulnar, and tibial fractures were managed with SLP. Surgical records, fracture healing, complications, and lameness were reviewed during scheduled rechecks.
