Dislocation of the shoulder caused by fibrous deltoid muscle after intramuscular injection antibiotic(s) in children

ABSTRACT

Dislocation of the shoulder after intramuscular injection antibiotic(s) is rare and this conditon was limit described in literature. Our purposes were: (1) determining the clinical symptoms, X-ray and CT findings; and (2) determining the indications and the surgical technique and evaluation of the surgical result. Material and methods: 62 children (29 females, 33 males) aged from 4 to 16 years were included. Clinical and X- ray findings were analysed for anterosuperior subluxation or dislocation of humeral head. The patients were operated to release of origin or insretion of the mild Deltoid muscle or Z plasty of this one. Surgical procedures provided good result in 75.3 percent, fair in 24.7 percent and there were no infection or neuromuscular complication in these cases. Conclusions: This condition always resulted from repeated Deltoid intramuscular injection. The surgical treatment with resection of fibrous portions constantly gives relief of symptoms and provides good function.
