Late-Onset Sacroiliac Osteoarthritis After Surgical Symphysiotomy: A Case Report.

A 35-year-old female presented with right-sided gluteal pain and difficulty in walking 10 years after surgical symphysiotomy. Radiograph of the pelvis and bilateral hip joints showed osteoarthritis of the right sacroiliac joint with pubic diastasis of 1.5 cm. She was operated with pubis symphysis reduction and fixation using two orthogonal plates with one iliosacral screw. Postoperative period was uneventful. She was able to walk independently after three months of fixation. Follow-up at 18 months showed complete relief of symptoms with maintenance of reduction and no hardware breakage. The Lindahl score was 78, indicating an excellent outcome.
