Recurrent complex regional pain syndrome after minor hip surgery

Complex regional pain syndrome (CRPS) Type I, a chronic pain disorder, occurs in the sequel of certain predisposing conditions. Recurrence may be observed in 4%–10% of cases in the same or another limb. There are no specific parameters to prevent CRPS after surgery or trauma. However, some authors have reported several recommendations about surgical techniques and Vitamin C supplementation. We report a case who had CRPS Type I history before and developed recurrent CRPS Type I in the lower limb due to surgery for osteonecrosis of the hip. We observed significant improvement with physical therapy and medication.
