title: Myositis ossificans around shoulder following military training programme.
abstract: The myositis ossificans around shoulder in military recruits are not reported yet. Three young male soldiers presented with complaints of palpable mass at the anterior aspect of shoulder; tenderness around the superior part of deltopectoral groove close to acromioclavicular joint; and restriction of shoulder motion. They also noticed ecchymosis and pain around the coracoid process and anterior shoulder region during regular firing exercises. Plain X-rays and computerized tomography showed extra-capsular, dense, irregular structure in the space between pectoralis and deltoid muscles which correlated with heterotopic bone. One patient refused surgical intervention because of the completion of his military serving period. Surgical excision was performed for the other two patients. During surgical exploration, both ossified masses were found in deltopectoral region and mostly in fibers of clavicular and acromial parts of deltoid muscle. Pathological reports confirmed the structure of masses as mature trabecular bone. Postoperatively indomethacin treatment and active shoulder exercises were started until the full range of motion was regained. Mini soft bag was used on the rifle contact area of the shoulder. No complications or recurrences were observed during the 24 months of followup period.
