PURPOSE To report the radiological and clinical results of revision total hip arthroplasty (THA) with femoral impaction bone grafting (IBG). METHODS 4 men and 9 women (15 hips) aged 38 to 84 years underwent revision THA with femoral IBG using Elite plus stems for aseptic loosening or infection. RESULTS The mean follow-up duration was 7.7 years. The Harris hip score improved from 61.7 to 83....

Unlinked total elbow arthroplasty (TEA), which has no mechanical connection between the humeral and ulnar components, has theoretical advantages based on its near-normal elbow kinematics and the preservation of bone stock. Unlinked TEA is appropriate only for patients who have limited bone loss or limited deformity and good ligamentous function. This is because postoperative instability has bee...

PURPOSE To report the clinical and radiographic results and complications of the Delta III reverse prosthesis. METHODS 24 women and 2 men aged 62 to 84 (mean, 75) years underwent total shoulder replacement using the Delta III reverse prosthesis. Patient diagnoses were massive rotator cuff tear (n=20), disabling sequelae of proximal humeral fractures (n=3), and failure of an unconstrained arth...

Background: Aseptic loosening of massive bone tumour implants remains one of the major causes of prosthesis failure. Question: The hypothesis of this study was that an osteointegrated hydroxyapatite (HA) coated collar would reduce the incidence of aseptic loosening around the cemented intramedullary stem in distal femoral bone tumour prostheses. Methods: Twenty-two patients were pair matched in...

Nine uncemented hip prostheses of modular design were revised because of late infection (2 cases), femoral stem loosening or fracture (2), loosening of threaded cups (3) and protrusion of bipolar cups (2). At surgery we found tissue discoloration and macroscopic corrosion in four of the nine prostheses, located at the head-neck junction. Histological examination in most cases showed extensive n...

Although about 200000 cementless Zweymüller-Alloclassic total hip arthroplasties (THAs) were carried out worldwide in the last decade, the survival analysis of these prostheses was not available in the 2000 report of the Swedish national hip arthroplasty registry. We report a prospective survivorship analysis of 200 consecutive grit-blasted cementless Alloclassic primary THAs carried out since ...

We report a case of impingement in a metal-on-metal total hip replacement causing both notching of the femoral stem neck and aseptic loosening of the acetabular component. The acetabular component was inserted in excessive anteversion. The femoral stem and acetabular components were retrieved. A larger femoral head was used, and an acetabular component was placed in a less anteverted position. ...

BACKGROUND AND PURPOSE There is considerable controversy about the treatment of complex, displaced proximal humeral fractures. Various types of head-preserving osteosynthesis have been suggested. This prospective case series was designed to evaluate the perioperative and early postoperative complications associated with fixed-angle implants and to record outcome after bone healing. PATIENTS A...

The functional outcome of hemiarthroplasty in displaced proximal humeral 3- and 4-part fractures or fracture dislocations in elderly patients is frequently unpredictable and depends on the position of the prosthesis and tuberosity fixation. Reverse shoulder arthroplasty represents an alternative in elderly patients. The purpose of this study was to report the results of a retrospective series o...

Aseptic loosening of artificial joints is the leading cause of failure for patients who receive total joint arthroplasty. Prior reports indicate that bone marrow mesenchymal stem cells (BSMC) are critical in the stabilization of implanted artificial joints, and that deregulated interaction between BMSCs and artificial joint derived particles is a risk factor for aseptic loosening with an unknow...
