We have three cases of muscular contractures due to intramuscular injections.
The three cases are followings;
1. 18 years old girl, who has mild contracture of bilateral rectus femoris muscles with cutaneous nerve entrapment,
2. 6 years old girl, who has severe contracture of left rectus femoris muscle with abnormal ossification of the origin of the rectus femoris,
3. 17 years old boy, who has severe contracture of bilateral gluteal muscles with sciatic nerve disturbance.
We will discuss about the new complaints of the muscle contracture, risks of the conservative treatment and suitable age of surgical treatment for gluteal muscle contracture.
