Fracture of the femoral prosthesis neck following total hip arthroplasty is not common. We report a case of femoral prosthesis neck fracture in an adult male patient following modular, uncemented total hip arthroplasty. This case report further emphasizes the importance of the potentially high loading situation in the prosthetic femoral neck. On the other hand, the occurrence of a femoral prost...

BACKGROUND AND PURPOSE We performed a randomized study to determine the migration patterns of the Spectron EF femoral stem and to compare them with those of the Charnley stem, which is regarded by many as the gold standard for comparison of implants due to its extensive documentation. PATIENTS AND METHODS 150 patients with a mean age of 70 years were randomized, single-blinded, to receive eit...

AIM The accuracy and inter-observer reliability (IOR) of acetate templating on hard copy X-rays in 33 primary total hip arthroplasties as measured by consultant and trainee surgeons was analyzed to find out how accurate are junior surgeons undertaking specialty training. METHODS The study was questionnaire-based using a prospective cohort over a 4 weeks period. The Surgeon measurements of ace...

PURPOSE To assess the treatment outcome of revision hip arthroplasty for Vancouver type B3 periprosthetic femoral fractures using a modular distally cemented stem. METHODS 22 men and 14 women (37 hips) aged 66 to 79 (mean, 70) years underwent revision hip arthroplasty for Vancouver type B3 periprosthetic femoral fractures. The indication for surgery was periprosthetic fracture with stem loose...

Is the proximal bone resorption around the femoral stem after hip arthroplasty really caused by reduced stress?

Avascular necrosis (AVN) of the femoral head is a progressive disease that predominantly affects younger patients. Although the exact pathophysiology of AVN has yet to be elucidated, the disease is characterized by a vascular insult to the blood supply of the femoral head, which can lead to collapse of the femoral head and subsequent degenerative changes. If AVN is diagnosed in the early stages...

BACKGROUND Hip prostheses with short anatomical stems were designed for metaphyseal fixation and to spare bone stock. We present a study of a short anatomical femoral stem used in all age groups of patients with Dorr A and B type of femora. METHODS We reviewed radiographs of 85 hips in 74 patients who had a cementless total hip arthroplasty with a short anatomical 80 mm femoral stem designed ...

We prospectively evaluated the long-term results of a technique using the Mennen plate to contain impacted allograft and support cemented Exeter stem revision fixation for the treatment of three B3 periprosthetic femoral fractures (PFFs). Three patients with a median age of 77 years were followed-up for a median of 84 months. In all cases the stem bypassed the distal fracture line by a median l...

Metal-on-metal (MoM) bearing in total hip replacement (THR) has a high failure rate due to adverse reaction to metal debris (ARMD). There is a spectrum of soft tissue and bony changes in ARMD including muscle necrosis and osteolysis. In our institution, more than 1500 MoM THRs were implanted since 2003. Recently, we have revised significant numbers of these. We report our experience and managem...

We have carried out a prospective, randomised study designed to compare the long-term stability of the stem of cementless femoral implants with differing surface configurations. A total of 50 hips (46 patients) was randomised into two groups, according to whether the medullary stem had been grit blasted (GB) or coated with hydroxyapatite (HA). Both femoral prostheses were of the same geometrica...
