Narrowing of the femoral neck after resurfacing arthroplasty of the hip has been described previously in both cemented and uncemented hip resurfacing. The natural history of narrowing of the femoral neck is unknown. We retrospectively measured the diameter of the femoral neck in a series of 163 Birmingham hip resurfacings in 163 patients up to a maximum of six years after operation to determine...

PURPOSE To evaluate the effect of prosthesis design on stress profile in the proximal femur after hip resurfacing. METHODS The von Mises stress profile of the native femur was simulated and compared with that of resurfaced femurs using various prosthetic materials (titanium, cobalt-chrome, ceramic), stem lengths (normal, half, short, and no stem), and femoral head coverage (shell size) [260 d...

This study compared the demographic, clinical and patient-reported outcomes after total hip replacement (THR) and Birmingham Hip Resurfacing (BHR) carried out by a single surgeon. Patients completed a questionnaire that included the WOMAC, SF-36 scores and comorbid medical conditions. Data were collected before operation and one year after. The outcome scores were adjusted for age, gender, como...

BACKGROUND Multimodal analgesia following total hip arthroplasty has been shown to improve patient satisfaction, participation with physical therapy, and allow early return to self care. Liposomal bupivacaine is a formulation of local anesthetic which has the potential to provide anesthesia for up to 72 hours following administration. The purpose of this study was to compare the effectiveness o...

85 years old male patient was admitted with a right-sided perTrochanteric proximal femur fracture following a mechanical fall onto his right side sustained at home. This was an isolated and closed injury with no associated neurovascular deficit. He had previously undergone a Birmingham hip resurfacing (Smith & Nephew®) to his right hip 12 years previously. This had been an uncomplicated surgery...

Arthroscopy of the native hip is an established diagnostic and therapeutic procedure. Its application in the symptomatic replaced hip is still being explored. We describe the use of arthroscopy of the hip in 24 symptomatic patients following total hip replacement, resurfacing arthroplasty of the hip and partial resurfacing (study group), and compared it with arthroscopy of the native hip in 24 ...

Short-term femoral neck fracture is a primary complication associated with contemporary hip resurfacing. Some fractures are associated with neck notching, while others occur in the absence of notching. These unexplained fractures may be due to large magnitude strains near the implant rim, which could cause bone damage accumulation and eventual neck fracture. We used statistically augmented fini...
