Ischemic contracture

Japanese: 阻血性拘縮

This is a condition in which muscle tissue is severely damaged and replaced by fibrous scar tissue due to impaired blood flow to the muscle, causing the muscle to lose elasticity and limit joint movement, resulting in deformity. Also called Volkmann's contracture, it is often caused by elbow joint trauma in children, especially when a supracondylar fracture of the humerus is caused by binding with a plaster cast. In other words, when a supracondylar fracture of the humerus occurs, swelling of the joint becomes quite significant over time, but the swelling increases even more when reduction manipulation is performed, especially if this is repeated several times.

Japanese:

筋肉の血行障害のため，筋組織が強く障害されて繊維性の瘢痕（はんこん）組織に置き換えられ，筋肉の伸縮性が失われて関節の可動制限をきたし，変形を生じたものをいう。フォルクマン拘縮Volkmann’s contractureとも呼ばれ，小児の肘関節部外傷とくに上腕骨顆上骨折の際ギプスによる緊縛で生ずることが多い。すなわち上腕骨顆上骨折の際，時間の経過とともに関節部の腫張はかなり著しくなるが，整復操作，とくにこれが何度か繰り返し行われた場合には腫張がいっそう増す。
