大腿四頭筋拘縮症の治療成績

抄録

Forty-one patients with quadriceps contracture involving 49 limbs due to repeated intramuscular injections were treated between 1976 and 1985. Adequate follow-up studies were obtained from 37 patients (45 limbs). The operations were performed following the muscle belly approach which includes transverse division of rectus and scarred portion of vasti. The result was generally excellent. In all cases, the angle of knee flexion on prone position became better than 60° and all cases except 2 gained better than 130° of knee flexion in supine position. To prevent large dimple of thigh, we divided rectus in two steps at some distance.
