Percutaneous balloon kyphoplasty for the vertebral compression osteoporotic and pathological fracture: one-year retrospective study of 112 patients.

Aim: The aim of the study was to look for the effectiveness of percutaneous balloon kyphoplasty in the management of vertebral compression osteoporotic and pathological fracture.

Methods: A retrospective analysis of 112 patients with 198 symptomatic wedge vertebral compression fractures who were treated by percutaneous balloon kyphoplasty was done. Visual Analogue pain (VAP) scale, Oswestry Disability index (ODI) and Short Form (SF-36) were used to look for the outcome.

Acetabular revision surgery with the uncemented oblong BOFOR Cup--early to midterm results.

Introduction: Failure of acetabular components frequently leads to bone loss with extensive elongated defects in the surrounding bone. In these cases the use of an oblong cup has been described as an option for acetabular reconstruction. We report the longest follow up results obtained with this implant to date.

Periprosthetic osteolysis due to metastatic renal cell carcinoma: a case report.

Failure of total hip arthroplasty through septic or aseptic loosening, periprosthetic fracture, or recurrent dislocation is well recognized and understood. We present an unusual cause of failure of total hip replacement which occurred on a 79 year old gentleman: that of prosthetic loosening secondary to malignant infiltration around components. Our aim is to highlight the fact that malignant infiltration should be considered as part of the differential diagnosis in aseptic and septic loosening of prosthetic implants.
