Case Reports

Case: A female with 24 years of follow-up who received multiple intramuscular injections of penicillin in the buttock at age 2 years. By age 6 years, she had left hip subluxation and underwent operative soft-tissue release and femoral plating. At age 12 years, she developed progressive anterior hip dislocation and had release of the gluteal contracture, open reduction, and femoral osteotomy. Currently, she is aged 26 years, fully employed, and active at home.

Conclusions: This is the first reported case associated with anterior hip dislocation after progressive post-injection gluteus muscle fibrosis with a follow-up of 24 years.
