Outcome of partial medial epicondylectomy for cubital tunnel syndrome.
Partial medial epicondylectomy aims to eliminate potential drawbacks of total epicondylectomy for treatment of cubital tunnel syndrome. In this series, we retrospectively evaluated 80 patients (80 elbows) who had partial medial epicondylectomies for established cubital tunnel syndrome. Our main purpose was to compare clinical outcomes among partial, minimal, and total epicondylectomies. Specific attention was given to the functional outcome in severely impaired patients, and potential postoperative complications of total epicondylectomy, such as elbow instability, and medial elbow pain. Preoperatively, 16 patients were classified as having McGowan Grade I lesions, 40 had Grade II lesions, and 24 had Grade III lesions. The mean followup was 32 months (range, 26 months-4.2 years). There was improvement of at least one McGowan grade in 86.2% of the patients, with a 66.7% improvement in severely impaired patients (McGowan Grade III lesions). There was no ulnar nerve palsy, no ulnar nerve subluxation, or medial elbow instability. However, 45% of patients reported mild pain at the 6-month followup. Partial medial epicondylectomy seems to be safe and reliable for treatment of cubital compression neuropathy at the elbow. ⋯ Therapeutic study, Level IV (case series).

Postoperative infections in interbody fusion for degenerative spinal disease.
Scant literature exists on the treatment of infection after interbody fusion. Some authors advocate removal of the interbody grafts. Salvage of the grafts was possible in 92.3% (12 of 13) of the infections in a series of 326 consecutive patients with degenerative spinal diseases treated by three surgeons. Posterior interbody fusion and posterolateral instrumented fusion was performed in 267 patients and anterior interbody fusion was done in 59 patients. Eight infections in the first group (3%) and six in the second group (10.1%) were identified. Mean followup was 18 months (range, 12-38 months). All infections were early, presenting at a mean of 18 days (range, 11-28 months). All but one infection were in the posterior wound and deep. A high number of risk factors were present in these patients. Initial treatment included wound debridement and broad spectrum antibiotics, until culture results indicated the final antibiotic regimen. Infection recurred as osteomyelitis in one patient with multiple previous surgeries and anterior/posterior fusion. This was treated with removal of the posterior instrumentation and the interbody graft and extensive anterior/posterior reconstruction. Clinical outcomes were good in 10 patients, fair in two and poor in one using the Stauffer-Coventry scale. One pseudarthrosis was identified in a patient with anterior interbody fusion at final followup. Salvage of the interbody graft and retaining the instrumentation was safe in most cases in the presented series and did not adversely affect outcome. ⋯ Therapeutic study, level IV (case series).
