Uncemented Porous Tantalum Acetabular Components: Early Follow-Up and Failures in 599 Revision Total Hip Arthroplasties.

Background: The purpose of this study was to determine the early outcomes of 599 cases of revision THA performed using a porous tantalum cup.

Methods: Clinical and radiographic data was sought in all patients at a minimum two years follow-up, after acetabular revision performed with a porous tantalum cup.

Results: Of the 599 cases identified, there were 51 re-operations in 47 patients (7.

A case report of bilateral mirror clubfeet and bilateral hand polydactyly.

We report a rare case of a patient with bilateral mirror clubfeet and bilateral hand polydactyly. The patient presented to our orthopaedic clinic with bilateral mirror clubfeet, each with eight toes, and bilateral hands with six fingers and a hypoplastic thumb. The pattern does not fit any described syndrome such as Martin or Laurin-Sandrow syndrome.

The effect of multi-level laminoplasty and laminectomy on the biomechanics of the cervical spine: a finite element study.

Laminectomy has been regarded as a standard treatment for multi-level cervical stenosis. Concern for complications such as kyphosis has limited the indication of multi-level laminectomy; hence it is often augmented with an instrumented fusion. Laminoplasty has emerged as a motion preserving alternative.

Osteochondral allograft of the talus.

Osteochondral lesions of the talus are being recognized as an increasingly common injury. They are most commonly located postero-medially or antero-laterally, while centrally located lesions are uncommon. Large osteochondral lesions have significant biomechanical consequences and often require resurfacing with osteochondral autograft transfer, mosaicplasty, autologous chondrocyte implantation (or similar methods) or osteochondral allograft transplantation.

Pre-operative and intra-operative factors related to shoulder arthroplasty outcomes.

The purpose of this study was to analyze pre-operative and intra-operative factors that affect the outcome of shoulder arthroplasty. We undertook a retrospective review of all shoulder arthroplasties performed at our institution between 1986 and 2003. Patients were contacted and outcomes were assessed using the Simple Shoulder Test and the Western Ontario Osteoarthritis of the Shoulder Index questionnaires.
