MRI findings in adolescent patients with acute traumatic knee hemarthrosis.

Background: Physical examination may be inconclusive in adolescents presenting with an acute traumatic knee effusion because of pain and guarding. The purpose of this study was to describe the magnetic resonance imaging (MRI) findings in adolescents with traumatic knee effusions and to compare injuries based on age, sex, and physeal maturity.

Methods: All MRIs using a knee trauma protocol performed at our institution over a 2-year period were evaluated.

The prevalence of hereditary neuropathy with liability to pressure palsies in patients with multiple surgically treated entrapment neuropathies.

Purpose: Hereditary neuropathy with liability to pressure palsies (HNPP) is an autosomal-dominant peripheral neuropathy that results from deletion of a 1.5-Megabase pair (Mb) segment of the short arm (p) of chromosome 17. Hereditary neuropathy with liability to pressure palsies increases susceptibility of peripheral nerves to pressure and trauma and can be associated with symptoms at multiple anatomic entrapment sites.

Results of an accelerated Ponseti protocol for clubfoot.

The Ponseti method has demonstrated excellent results when performed at weekly intervals, but it is not known whether correction can be accomplished in a shorter amount of time. This study evaluated the success in correction in relation to time between casts (5 or 7 days). The authors retrospectively reviewed 230 patients (319 clubfeet).
