Primary cementless total hip arthroplasty with an alumina ceramic-on-ceramic bearing: results after a minimum of twenty years of follow-up.

Background: The biological problems related to wear debris after total hip arthroplasty have stimulated renewed interest in alternatives to metal-on-polyethylene bearing surfaces.

Methods: We retrospectively evaluated the clinical and radiographic results of 100 patients who had undergone a total of 109 primary total hip arthroplasties with a cementless alumina ceramic-on-ceramic prosthesis between January 1985 and December 1989. The mean age of the patients at the time of the index arthroplasty was forty-six years.

Is obesity a contraindication for minimal invasive total knee replacement? A prospective randomized control trial.

Background: Although total knee replacement (TKR) has been proven a very successful treatment modality for the end-stage knee osteoarthritis (OA) in obese patients, the rehabilitation period often is long and painful. Minimal invasive surgery (MIS) has gained much attention in TKR promising fast and less painful recovery. However, little is known about the effectiveness of the technique in the obese adult population.

Aspiration alone versus aspiration and bupivacaine injection in the treatment of undisplaced radial head fractures: a prospective randomized study.

Hypothesis: Some physicians advocate that aspiration of elbow joint hematoma in radial head fractures is helpful not only for determining a mechanical block to motion from a fracture fragment but also for improving the elbow motion and pain. However, the supplementary role of intra-articular anaesthetic injection is unclear.

Materials And Methods: In this prospective randomized study, 40 patients with undisplaced radial head fractures (Mason I) were treated with elbow joint aspiration alone (20 patients) or aspiration plus intra-articular injection of 3 mL of bupivacaine 0.

Reconstruction of a missed posterior locked shoulder fracture-dislocation with bone graft and lesser tuberosity transfer: a case report.

Introduction: Posterior shoulder fracture-dislocation is a rare emergency condition with poor prognosis when there is a delay in diagnosis and presence of associated injuries.

Case Presentation: We present a case of a neglected four-part fracture-dislocation of the proximal humerus in a 34-year-old Greek woman. Except from the substantially displaced and comminuted tuberosity fractures, an anterolateral defect of approximately 50% of the articular surface was apparent.

Primary total-hip arthroplasty with the autophor 900-s fully porous coated stem in young patients seven to seventeen years of follow-up.

A total of 233 Autophor 900-S fully porous coated stems were implanted in 220 patients with an average age of 47.5 years and an average follow-up of 13.5 years.
