INTRODUCTION Temporo-mandibular joint ankylosis is a common cause of acquired deformity in children. PURPOSE Surgical correction of the ankylosis only leaves the patient with an uncorrected mandibular deformity. This study was to evaluate the use of distraction osteogenesis for simultaneous correction of the mandibular deformity. MATERIAL This study was done on six children with temporo-man...

INTRODUCTION Mechanical alignment deviation after total knee arthroplasty is a major reason for early loosening of the prosthesis. Achieving optimum cement penetration during fixation of the femoral and tibial component is an essential step in performing a successful total knee arthroplasty. Bone cement is used to solidify the bone and prosthesis. Thickness imbalance of bone cement leads to the...

Objective: Our aim was to establish the existence of intercellular communication through gap junctions (ICGJ) in synovial tissues and to show that gap junction communications in synovial tissue plays a role in the pathogenesis of synovitis in patients with rheumatoid arthritis (RA). Material and methods: Synovial tissues were obtained from patients with RA and osteoarthritis (OA) at the time of...

  Background: The aim of this review article is to analyze the results of high tibial osteotomy compared to unicompartmental knee arthroplasty in patients with unicompartmental knee osteoarthritis.   Methods: The search engine used was PubMed. The keywords were: "high tibial osteotomy versus unicompartmental knee arthroplasty". Twenty-one articles were found on 28 February 2015, but only eighte...

BACKGROUND A variety of methods are available for the fixation of femoral shaft fractures after total hip arthroplasty. However, few studies in the literature have quantified the performance of such repair constructs. The aim of this study was to evaluate biomechanically four different constructs for the fixation of periprosthetic femoral shaft fractures following total hip arthroplasty. METH...

This article analyzes the hip and knee reconstruction section of the Orthopaedic In-Training Examination (OITE). All of the hip and knee reconstruction questions from 2005 to 2009 were analyzed, and the following data were recorded: number of questions per year in the hip and knee section, total number of questions on the OITE per year, national average score by year in training, references cit...

The authors aim at reviewing the guiding principles in revision total knee arthroplasty according to a stepwise procedure. Strict preoperative planning is of paramount importance for this surgery. Thorough clinical history and physical exam, the assessment of limb deformity and knee range of motion as well as knee stability in flexion, extension and mid-flexion are crucial. Blood exam, standard...

Flexion instability in posterior-stabilized total knee arthroplasty is a relatively uncommon but distinct problem that is often underdiagnosed and may require surgical management. This retrospective study evaluated the authors' management strategy and assessed the results of revision surgery. The authors identified 19 knees that underwent revision for isolated flexion instability after primary ...

Total hip arthroplasty is an increasingly common procedure used to address degenerative changes in the hip joint due to osteoarthritis. Although generally associated with good results, among the challenges associated with hip arthroplasty are accurate measurement of biomechanical parameters such as leg length, offset, and cup position, discrepancies of which can lead to significant long-term co...

There is currently a growing demand for unicompartmental knee replacement (UKR) to treat degenerative osteoarthritis or osteonecrosis of a single compartment of the knee. This procedure has evolved significantly over the past three decades and we here present a brief review of the literature on this topic. This historical overview traces the hypotheses that have led to the modern state of the a...
