Fourteen patients with deltoid contracture, treated surgically between 1971 and 1986were evaluated after an average follow up of 8.9 years (range, two to sixteen years). Nine patients were afflicted on their left sides, four patients on the right, and one on both sides. Twlve patients were children who had received multiple intramuscular deltoid injections in infancy or childhood. The other two patients were adults. The average age at operation time of the child cases was 13.6 years (range, from eight to seventeen years). Seven the child patients complained of winging scapula. Two adult patients complained of pain in their shoulders. The average abduction contracture angle in all the shoulders was 23.7 degrees (range, from 10 to 45 degrees)
Of the fifteen oper a tive procedures, six were transections of the fibrous portion, seven were resections of the fibrous portion and two were resections of the fibrous portion and advancements of the posterior deltoid muscle
At follow up time the average abdu c tion contracture angle was 6.3 degrees (range, from 0 to 15 degrees). Winging scapula had vanished in all the cases and the recurrence of abduction contracture was not recognized in any patient
The average abduction contracture angle in the transection group was 25.0 degrees at pre-operation and 9.5 degrees at follow up. The average angle in the resection group was 25.7degrees at pre-operation and 5.3 degrees at follow up 2/6 patients in the transection group and 5/7 patients in the resection group complained of pain in their shoulders at follow up
The roentgenographic examinations showed, three humeral heads had been fla t tended slightly
Nine patients complained of their surgical scars and four patients asked for plastic surgery
Thirteen patients were satisfied with the results and only one patient was dissatisfied because of residual shoulder and back pain.
