Total hip and knee arthroplasty in patients with hereditary multiple exostoses.

To the authors' knowledge, few reports have been published in the English literature of using total knee arthroplasty and total hip arthroplasty for the treatment of hereditary multiple exostoses. This article describes 2 patients with hereditary multiple exostoses, 1 treated with total hip arthroplasty and 1 treated with total knee arthroplasty. Bony deformities make arthroplasty uniquely challenging in patients undergoing total hip or knee arthroplasty.

Cementless femoral fixation in total hip arthroplasty.

A number of cementless femoral stems are associated with excellent long-term survivorship. Cementless designs differ from one another in terms of geometry and the means of obtaining initial fixation. Strict classification of stem designs is important in order to compare results among series.

Outcomes of unicompartmental knee arthroplasty stratified by body mass index.

Patients who have high body mass indices can have disabling medial compartment knee osteoarthritis, which might benefit from unicompartmental knee arthroplasty (UKA). The purpose of this study was to compare clinical and radiographic outcomes of UKAs in patients with body mass indices (BMIs) greater and less than 35 kg/m(2). Thirty-four patients (40 knees) had BMIs of 35 kg/m(2) or greater, whereas the remaining 33 patients (40 knees) had BMIs below 35 kg/m(2), with 2-year minimum follow-up.

Chronic expanding hematoma of the lateral thigh and massive bony destruction after a failed total hip arthroplasty.

Pseudotumors have been described around both stable and failed total hip arthroplasties. The causes are varied and include polyethylene debris and masses associated with metal-on-metal bearings. We present a patient with a massive tumor of the thigh that grossly and pathologically was associated with recurrent bleeding and extensive bony destruction.

Atraumatic bilateral femur fracture in long-term bisphosphonate use.

Postmenopausal women with osteoporosis are commonly treated with the bisphosphonate class of medications, one of the most frequently prescribed medications in the United States. In the past 4 years, reports have been published implying that long-term bisphosphonate therapy could be linked to atraumatic femoral diaphyseal fractures. This article presents a case of a 67-year-old woman who presented with an atraumatic right femur fracture.
