Fifteen cases with ruptures of musculotendinous juncture of the medial head of the gastrocnemius muscle which occurred during sports activities were studied. Of these cases, 7 were males and 8 were females. The mean age was 36 years and 6 months with ages ranging from 15 to 56.Six of these cases were involved in track-and-field events, three in volleyball, two in softball, two in badminton, one in judo and one in recreational game. Prodromic symptoms such as dull aching of the affected leg were seen in 8 cases. All cases were injured in a position of the ankle joint in dorsiflexion with the knee joint in extension.Conservative treatments resulted in a satisfactory recovery of their activities of daily living in all cases.The results indicated that prophylactic stretching is of value for preventing this injury, especially in middle-aged players.

Traumatic myositis ossificans is well known to occur in the muscle hematoma as a result of a contusion or a strain.An 18-year-old male of traumatic myosits ossificans after contusion on his right anterior thigh while playing rugby football was reported. Five and seven days after the first injury he played rugby football and reinjured the same area. Three weeks after the reinjury he had increased anterior thigh pain and limited motion of the knee. When examined, the right quardriceps was tender and swollen in the antero-mid thigh. Flexion of the knee was about 80 degrees due to pain. Roentgenograms showed linear and cloudy calcification in the quardriceps muscle. His knee was immobilized, and he was given a non-steroid antiinflamatory agent for two weeks. After pain relief rehabilitation began with exercise to increase the range of motion. Four months after the first injury, the patient had no pain and limitation of knee flexion.Adolescents actively involved in contact sports are at risk for muscle trauma, which can results in myositis ossificans. The development of traumatic myositis ossificans is related to the severity of the quardriceps contusion.Recognition and appropriate therapy can reduce the associate disability.
