Popis: Contracture of the infraspinatus muscle has been recognized as a cause of shoulder lameness in hunting dogs. Electrophysiologic studies of four affected dogs indicated that infraspinatus contracture was a primary muscle disorder rather than a neuropathy. Histologically, affected tissues from six dogs showed degeneration and atrophy of skeletal muscle with fibrous tissue replacement. These findings supported the hypothesis that an acute traumatic event caused incomplete rupture of the infraspinatus muscle, leading to fibrosis and contracture. Seven dogs were successfully treated by infraspinatus tenotomy.
