Background:  Distal femur wedge osteotomies for varus or valgus alignment of the lower extremity could be done in either uniplanar or biplanar fashion.Union time and stability of the osteotomy site has been considered important in this anatomic region. In this study, clinical and radiographic findings of biplane distal femur osteotomy were reported. Methods: Clinical, functional, and radiologic...

OBJECTIVES To determine the effects of intraarticular step-off and lateral meniscectomy on the alignment of the articular axis, contact area, and pressures for lateral tibial plateau fractures. DESIGN Biomechanical cadaver study. INTERVENTION Six fresh cadaveric knees were used. A simulated split fracture of the lateral tibial plateau was reproducibly created by osteotomies, and articular s...

BACKGROUND The aims of our study were to evaluate the validation of measurement of weight-bearing lateral radiographs. Two hypotheses were tested: the measurements on the lateral radiographs are reliable, and a theoretical limit could be identified when a surgeon can "eyeball" an incongruous ankle joint on lateral radiographs. METHODS To test the first hypothesis, 3 experienced ankle surgeons...

BACKGROUND Locking compress plate, as external fixator, is an attractive technique for distal tibial fracture treatment. But it still remains unclear whether the external LCP has sufficient stiffness. Thus, the present study aims to make a comprehensive evaluation of the stiffness of external locking compress plate when it is used as an external fixator in distal tibial fractures treatment. M...

Moderate to severe hallux valgus is conventionally treated by proximal metatarsal osteotomy. Several recent studies have shown that the indications for distal metatarsal osteotomy with a distal soft-tissue procedure could be extended to include moderate to severe hallux valgus. The purpose of this prospective randomised controlled trial was to compare the outcome of proximal and distal Chevron ...

abstract   background: tibial torsion is one of the torsion density which rotating in the longitudes axis of the leg. to measure this deformity, different methods such as radiographic or clinical methods were presented and introduced. methods: in this quasi-experimental study, 30 male athletes were selected randomly. their tibial torsion angle was measured using ct scan, lavand, lokomso, foot p...

INTRODUCTION: Correct rotational alignment of the femoral component is one of the most important factors for successful total knee arthroplasty. The rotational position of the femoral component can be determined using bony landmarks, such as the transepicondylar axis, the posterior condylar axis, or the anteroposterior (AP) axis (Whiteside’s line). Rotational alignment of the femoral component ...

Damage to peripheral nerve tissue may cause loss of function in both the nerve and the targeted muscles it innervates. This study compared the repair capability of engineered nerve conduit (ENC), engineered fibroblast conduit (EFC), and autograft in a 10-mm tibial nerve gap. ENCs were fabricated utilizing primary fibroblasts and the nerve cells of rats on embryonic day 15 (E15). EFCs were fabri...

BACKGROUND High tibia osteotomy (HTO) is a common surgical operation for correction of genu varum deformity. In some patients, there are concurrent tibia vara and genu varum (bow leg). This study aimed to consider the possibility of better correction of bow leg deformity after double level tibial osteotomy (DLTO). MATERIALS AND METHODS A case series of 10 patients of genu varum in addition to...

BACKGROUND Restoration of the natural joint line is a cornerstone for kinematically aligned total knee arthroplasty (TKA). The purpose of this study was to investigate the relative orientation of the tibial growth plate (GP) with respect to the tibial plateau (TP) for possible application in predicting natural joint line for knees with highly advanced osteoarthritis patient at the time of kinem...
