Short-term functional outcome after hip resurfacing surgery.

Hip resurfacing arthroplasty is a popular method for treating late stage osteoarthritis, especially in young and active patients. Most studies presenting short-term follow-up after hip resurfacing present radiographic or dual clinician-patient-related outcome. These kinds of outcomes are influenced by interpretation of the clinician and do not tell us much about functional outcome from the patients perspective.

Incidence of low-grade infection in aseptic loosening of total hip arthroplasty.

Purpose: We investigated the hypothesis that many total hip arthroplasty revisions that are classified as aseptic are in fact low-grade infections missed with routine diagnostics.

Methods: In 7 Dutch hospitals, 176 consecutive patients with the preoperative diagnosis of aseptic loosening of their total hip arthroplasty were enrolled. During surgery, between 14 and 20 tissue samples were obtained for culture, pathology, and broad-range 16S rRNA PCR with reverse line blot hybridization.

Uncemented surface replacement for osteonecrosis of the femoral head.

From 1973 to 1982, we performed 40 uncemented surface arthroplasties using 27 Thomine and 13 Gerard cups in 32 patients with osteonecrosis of the femoral head (Ficat Stages 3 and 4). The median follow-up was 8 (3-12) years, with a median age at operation of 35 (19-60) years. Walking ability and mobility were improved, but relief from pain was the most significant improvement.

Saddle prosthesis after resection of a para-acetabular chondrosarcoma. A case report.

A case of para-acetabularly localized chondrosarcoma with involvement of the hip was treated by local excision and reconstruction with a saddle endoprosthesis resting at the ileum. At follow-up after 5 years, a spontaneous fusion had developed with good function; there were no signs of local recurrence.

[Congenital defects of tibia and fibula].

This study comprised 7 patients with longitudinal anomalies of the knee and leg classified in accordance with the 'classification of congenital limb deficiencies' introduced by Frantz and O'Rahilly. The anomalies were paraxial hemimelia of the fibula (4 instances), paraxial hemimelia of the tibia (6 instances). In the absence of the proximal tibia, therapy consisted of knee reconstruction according to Brown.
