The ratio of male to female was 1:1.2 (9:11). Their ages ranged from 17 to 52 years (mean 29.5 years), with a peak incidence in the 3rd decade (55%).

The lower extremity was exclusively involved, and the left side was more involved than the right. Symptoms were a burning sensation, tingling sensation, shooting pain and weakness. Other associated sequelae were local swelling, acute renal failure, delayed neurologic sequelae, and Volkman's contracture in that order. Of 20 cases, 6 showed abnormal findings in the electromyogram only, and 14 were abnormal in both electro-myogram and nerve conduction velocity.

Fifteen cases recoved within 3 to 6 months.
