The anteroposterior (AP) and medial-lateral (ML) dimensions of 200 consecutive osteoarthritic knees (100 males and 100 females) undergoing unilateral primary total knee arthroplasty were compared. For all patients, the mean AP dimension was 57.3 mm (range: 49-66 mm) and the dimension was 10.5% taller in height in men than women. The mean ML dimension was(More)
Although olecranon osteotomy provides excellent exposure of the distal humerus, enthusiasm for this approach has been limited by reports suggesting numerous complications. It has been suggested that specific techniques for creating and repairing an olecranon osteotomy may help limit complications. This paper describes a technique for olecranon osteotomy(More)
BACKGROUND CONTEXT Although the prevalence of indications and contraindications to lumbar total disc replacement (TDR) has been evaluated, no study to date has quantified the potential candidacy for cervical disc replacement in practice. PURPOSE To report the potential candidacy rate for cervical TDR from both an academic and private practice spine(More)
BACKGROUND Diffuse pigmented villonodular synovitis of the knee is a difficult tumor to eradicate. We report our experience with a combined open posterior and anterior synovectomy with and without adjuvant postoperative radiation therapy in patients with advanced extracapsular disease. METHODS A single surgeon operated on forty patients, with an average(More)
STUDY DESIGN Prospective radiographic analysis with clinical correlates. OBJECTIVE The purpose of this study was to determine whether patients with cervical plates protruding off the vertebral body more prominently than pre-existing osteophytes had higher rates of dysphagia, suggesting a mechanical role. SUMMARY OF BACKGROUND DATA Plate prominence due(More)
BACKGROUND CONTEXT Given the experience with anterior lumbar cages, the similar enthusiasm for total disc replacement (TDR) and the economic incentives driving use of this new technology, it is important to document reasonable expectations as to the incidence of patients with appropriate indications for this new technology. PURPOSE To document(More)
PURPOSE To determine whether the radial nerve should be explored when there is a complete sensory and motor deficit after a high-energy fracture of the humeral diaphysis. METHODS Twenty-four patients aged 16 years or older with a high-energy, diaphyseal fracture of the humerus and complete motor and sensory radial nerve palsy were reviewed(More)
STUDY DESIGN Technical note. OBJECTIVE To demonstrate a controlled extension osteotomy technique of the cervical spine in a prone position and using the head elevator mechanism on the Jackson operating table to correct a chin-on-chest deformity in a patient with ankylosing spondylitis. SUMMARY OF BACKGROUND DATA Catastrophic cord injury causing(More)
STUDY DESIGN Prospective case controlled. OBJECTIVE To determine the outcome after microdiscectomy in patients with disc herniation, concordant sciatica, and low-back pain with Modic I and II degenerative changes compared with similar patients without Modic changes. SUMMARY OF BACKGROUND DATA The decision to perform a microdiscectomy versus a fusion or(More)
Nonunion of distal tibia metaphyseal fractures after trauma is a major problem. Treating these nonunions is made more challenging by the presence of symptomatic ipsilateral tibiotalar arthrosis. The current study examined the use of the 90 degrees cannulated blade plate as an alternative method of stable internal fixation for 13 distal tibia metaphyseal(More)
