- Static muscle shortening due to tonic spasm or fibrosis, to loss of muscular balance, the antagonists being paralyzed or to a loss of motion of the adjacent joint. [L. contractura, fr. con-traho, to draw together]- Dupuytren c. a disease of the palmar fascia resulting in thickening and shortening of fibrous bands on the palmar surface of the hand and fingers resulting in a characteristic flexion deformity of the fourth and fifth digits.- fixed c. SYN: organic c..- functional c. muscular shortening that ceases during sleep or general anesthesia, caused by prolonged active muscle contraction.- ischemic c. of the left ventricle irreversible contraction of the left ventricle of the heart, seen as a complication in the early period of cardiopulmonary bypass and now avoided by appropriate cardioplegic solutions. SYN: myocardial rigor mortis, stone heart.- organic c. c., usually due to fibrosis within the muscle that persists whether the subject is conscious or unconscious. SYN: fixed c..- Volkmann c. ischemic c. resulting from irreversible necrosis of muscle tissue, produced by a compartment syndrome; classically involves the forearm flexor muscles.
