Three cases of forearm muscle hernia are described. Their aetiology differed but, in all three, symptoms were sufficiently severe to interfere with the patient's work. Surgical repair of the myocoeles, by closure of the fascial defects using lata onlay grafts or an interweave of palmaris longus tendon, produced complete resolution of symptoms and enabled the patients to return to full employment.
A case of flexor pollicis longus tendon rupture as a complication of a Colles' fracture in a 17-year-old male is described. Tendon repair by means of a one-stage tendon graft produced a good functional result.
A case of ulnar nerve compression at the wrist caused by a reversed palmaris longus muscle is reported. We are not aware of any previous reports of ulnar nerve compression due to this particular muscle anomaly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
