Early periprosthetic bone remodelling around cemented and uncemented custom-made femoral components and their uncemented acetabular cups.

Introduction: Periprosthetic bone remodelling after total hip replacement may contribute to aseptic loosening of the prosthesis. The selection between cemented and uncemented fixation of the stem is mainly determined by patient's age, general constitution and CT scan-estimated bone quality; intra-operative observation may ultimately influence the choice of the fixation method. The influence of cemented versus uncemented stem fixation on periprosthetic bone remodelling around the uncemented cup has, to our knowledge, never been studied until now.

Pyoderma gangrenosum following trauma of the knee: a case of pathergy and review of orthopaedic cases.

Pyoderma gangrenosum (PG) is a rare noninfectious neutrophilic dermatosis. Its course can be mild or malignant, chronic or relapsing with remarkable morbidity. We describe a case of PG, which presented with severe wound breakdown following a closed tibial plateau fracture of the left knee.

A custom-made guide-wire positioning device for hip surface replacement arthroplasty: description and first results.

Background: Hip surface replacement arthroplasty (SRA) can be an alternative for total hip arthroplasty. The short and long-term outcome of hip surface replacement arthroplasty mainly relies on the optimal size and position of the femoral component. This can be defined before surgery with pre-operative templating.

Complete slippage of capital femoral epiphysis: total hip arthroplasty with custom-made stem.

Slipped capital femoral epiphysis occurs in adolescents, most often shortly after the onset of puberty. In patients suffering form renal osteodystrophy, the incidence is higher and the condition usually occurs at a younger age. Metabolic changes induce weakening of the bone, which makes the hip joint vulnerable.

Arthroscopy of the knee in elderly patients: cartilage lesions and their influence on short term outcome. A retrospective follow-up of 183 patients.

We reviewed all patients of 65 years and older (n=183), who underwent a knee arthroscopy between 2004 and 2005. The purpose of our study was to determine the frequency and severity of cartilage lesions and their influence on short-term clinical outcome. Signs of osteoarthritis (OA) were absent or minor on pre operative plain radiographs in 30.
