Traumatic isolated injury of deltoid muscle is a rare nosological orthopedic injury that occurs in 1,3 % of all shoulder joint injuries. In normal state function of shoulder joint is provided by deltoid muscle up to 50 % of capacity in scapular area. Degree of abolition of function of shoulder joint depends on the degree of deltoid muscle injury. Differential diagnosis is necessary to conduct with other traumatic injuries accompanied with such upper limb dysfunctions as chronic posterior humerus head dislocation, injury of rotatory cuff tendon, chronic complete or partial disorder of deltoid muscle integrity. The article contains clinical case of diagnostics and surgical treatment of the patient with isolated old deltoid muscle injury of more than 2 years accompanied with combined contracture of shoulder joint. Check-up examination in 6 months after the operation showed full restoration of a function of upper limb and no complaints. Results of control MRT examination of shoulder joint in 11 months after the operation showed full adhesion of tendomuscular autograft with acromial process of scapula.
