Posterior Interosseous Nerve Palsy due to Parosteal Lipoma
Abstract
Lipomas are extremely common benign soft tissue tumours that are usually subcutaneous and asymptomatic. Occasionally, lipomas can occur in deeper soft tissue planes and when adjacent to the neck of the radius they can cause compression of the posterior interosseous nerve. Five such cases are described. An anterior approach to excision of the lipoma is recommended.
