The appearance of the piriformis muscle syndrome in computed tomography and magnetic resonance imaging. A case report and review of the literature.

The piriformis syndrome (PS) is a controversial cause of hip pain because of the lack of objective findings to support the diagnosis. Computed tomography (CT) and magnetic resonance (MR) imaging revealed PS in a 27-year-old woman. This case may be one of the first reports in the literature on a piriformis muscle enlargement documented by CT and MR imaging.

Pediatric update #10. Treatment of displaced supracondylar fractures of the humerus in children by closed reduction and percutaneous pinning.

In a retrospective study of 25 displaced supracondylar fractures of the humerus in children, treatment by closed reduction and percutaneous pin fixation was reviewed. Follow-up averaged 16 months. Loss of elbow motion and carrying angle were graded according to Flynn's criteria.

Treatment of acquired hip subluxation in cerebral palsy.

Fifty-seven children with cerebral palsy and subluxated hips underwent soft tissue releases to obtain hip reductions. Eight patients in Group I (preoperatively mildly subluxated hips) had postoperative bracing, all with good results. Twenty-two unbraced patients in Group I had 14 good, 5 fair, and 3 poor results.

A simple method of hip arthrodesis.

A technique of intraarticular hip arthrodesis using a cancellous screw to provide compression across the joint is introduced. We present four patients in whom this method was successful, resulting in solid fusion and pain relief at follow-up.

Extension-abduction contracture of the spastic hip.

Patients with cerebral palsy and fixed hip extension are often unable to sit and therefore lose social and educational opportunities. At Texas Scottish Rite Hospital (Dallas, TX, U.S.
