INTRODUCTION development dysplasia of the hip is one of the common disorders in pediatric orthopaedics. This requires an early orthopaedic treatment. Neglected cases can lead to hip dislocation, which has an incidence of 1.4 / mille new-borns, being bilateral in 70-80% of cases and prevalence of girls being 7 / 1-4 / 1 (girls / boys). Congenital hip dislocation requires a complex surgical and o...

The motivation of the present work is the computational simulation of hip replacement surgery by means of a finite element approach based on open system thermodynamics. Its key feature is a non-constant material density, which is allowed to adapt with respect to changes in the mechanical loading environment. From a computational point of view, the density is treated as an internal variable. Its...

BACKGROUND Total knee replacement (TKR) is the commonest surgical procedure for patients with severe pain and impaired physical function following end stage knee osteoarthritis. The hip abductors are well renowned in stabilization of the trunk and hip during walking, maintaining the lower limb position, and transferring the forces from the lower limbs to the pelvis. OBJECTIVE To assess the ef...

Total hip replacement is an often-performed orthopedic surgical procedure; the amount of procedures undertaken will increase since our life expectancy is growing. In order to optimize function, hip biomechanics should be restored to as near normal as possible. The goal of this pilot study was to determine whether or not it is feasible to compute the vectorial hip reaction force pathways on the ...

Background: According to the National Association of Orthopedic Nurses (NAON), research indicates that evidence-based practice for post-operative hip and knee replacement patients includes early mobilization several hours following surgery. Findings indicate that early mobilization on the day of surgery directly correlates to decreased pain, increased distance ambulated and decrease in length o...

Metallic endoprostheses are used for oncological reconstruction around the proximal femur and hip joint. Common modes of failure with hemiarthroplasty or standard hip arthroplasty after proximal femoral replacement include dislocation, late hip pain, and infection. The authors reviewed hospital records to identify patients undergoing constrained tripolar hip arthroplasty for oncological reasons...

BACKGROUND Total hip replacement is increasingly used in active, relatively healthy elderly patients with fractures of the femoral neck. Dislocation of the prosthesis is a severe complication, and there is still controversy regarding the optimal surgical approach and its influence on stability. We analyzed factors influencing the stability of the total hip replacement, paying special attention ...

OBJECTIVE To examine the necessity and cost-effectiveness of interpretation by radiologists of orthopedic radiographs obtained for patients who undergo total hip or knee replacement. DESIGN A prospective study. Serial preoperative and postoperative x-ray films of the joint in patients scheduled to undergo total hip or knee joint replacement during one calendar year were interpreted by both ra...

Objective: To describe the most common forms of hip replacement complications that can prevail postoperatively and how obesity can impact the extent and severity of these complications. Methods: Relevant literature and research evidence concerning complications that occur after primary joint hip arthroplasty or joint replacement surgery, plus those that discussed issues of obesity in this conte...

BACKGROUND The question of how best to reduce waiting times for health care, particularly surgical procedures such as hip and knee replacements is among the most pressing concern of the Canadian health care system. The objective of this study was to test the hypothesis that significant seasonal variation exists in the performance of hip and knee replacement surgery in the province of Ontario. ...
