Treatment of a symptomatic forearm muscle herniation with a wrap-around fascia lata graft.

Muscle herniation in the extremity is a well-recognized cause of symptomatic pain on exertion. Only 17 cases involving the upper limb has been previously described, 11 of them involving the anterior compartment of the forearm and only 2 were caused by strenuous exertion. Treatment for this condition ranged from nonsurgical, primary closure with palmaris longus interweave, formal fasciotomy, to closure with a tensor fascia lata graft.
