CONTRACTURA DE VOLKMAN PDF

Volkmann's contracture is a permanent flexion contracture of the hand at the wrist , resulting in a claw-like deformity of the hand and fingers. Passive extension of fingers is restricted and painful. Any fracture in the elbow region or upper arm may lead to Volkmann's ischemic contracture, but it is especially associated with supracondylar fracture of the humerus. Volkmann's contracture results from acute ischaemia and necrosis of the muscle fibres of the flexor group of muscles of the forearm , especially the flexor digitorum profundus and flexor pollicis longus. The muscles become fibrotic and shortened. The condition is caused by obstruction on the brachial artery near the elbow, possibly from improper use of a tourniquet , improper use of a plaster cast , or compartment syndrome.

Twenty-five patients treated between and were evaluated. The method of treatment was related to the severity of the infarction, ranging from conservative to free vascularized muscle transplantation. Although the study population was small, we could observe a wide range of functional outcome. Substantial improvement of function was obtained in patients who had free vascularized muscle transplantation.

Unfortunately in one patient with an occlusion of the distal brachial artery and an insufficient flow through the collateral circulation of the radial artery, the gracilis muscle was lost.

Tendon lengthening had unsatisfactory results because of recurrence of the contracture. Excision of fibrotic muscle tissue, neurolysis and tenolysis sometimes combined with a tendon transfer gave good hand function results in patients with sufficient remaining muscle tissue. In most of the patients in whom the contracture developed during childhood, a difference in forearm length was observed. Ingles 28 febrero, General Vistos. Compartir Facebook Twitter.
