RESUMEN
INTRODUCTION: Total hip arthroplasty after McMurray's osteotomy increases the operative difficulties and decreases the chances of better outcome. With the advent of modular femoral stems, minute changes can be done to individual joints, which allow intraoperative flexibility and better post-operative outcome. Thus, it should be considered as an option for complicated cases. CASE REPORT: We report a case of a 35-year-old female with chief complain of pain in the left hip while walking for the past 2 years. The patient also had difficulty in squatting and sitting cross legged. History of fracture in the left hip at 4 years of age for which McMurray's osteotomy was done. The patient was operated with total hip arthroplasty using modular Sivash range of motion (S-ROM) stem. CONCLUSION: Modular S-ROM total hip arthroplasty is a good option for treatment in cases with previous osteotomy in femur.
