Complex Regional Pain Syndrome Following Percutaneous Trigger Thumb Release

  • 1Department of Orthopaedic Surgery, National Health Insurance Service Ilsan Hospital, Goyang, Korea. esmeron@naver.com


Trigger finger is one of the most common causes of hand pain and disability. Persistent trigger finger after conservative treatment has been managed with surgical release of the A1 pulley. Percutaneous A1 pulley release is being increasingly performed and many authors have reported comparable outcomes with open surgical release. However, complications have been reported, including incomplete release, flexor tendon injury, and neurovascular injury due to the blind nature of the procedure. We report on a case of a 49-year-old female who presented with features of a type I complex regional pain syndrome (CRPS) following percutaneous A1 pulley release. CRPS is a relatively common complication occurring after trauma and surgical procedures of the upper extremities. We experienced a case of CRPS following percutaneous A1 pulley release which was treated effectively following early diagnosis and through a multidisciplinary approach including physical therapy and medication.
