Recurrent carpal tunnel syndrome:Evaluation and treatment of the possible causes

摘要

AIM to investigate the causes of the recurrent carpal tunnel syndrome(CTS)and implemented surgical interventions.METHODS Four hundred and eighty-seven patients,who were diagnosed with CTS and underwent surgical intervention between October 2016 and September 2007,were evaluated in this retrospective study.The age,gender,physical evaluation findings,electrophysiological examination reports and implemented surgical treatment methods were analyzed.RESULTS Thirty-nine of the cases were operated due to recurrent CTS.Further examination of the patients with recurrent CTS revealed that ten cases had diabetic polyneuropathy,three cases had hypothyroidism,two cases had rheumatoid arthritis and one case had systemic amyloidosis.Postoperative electromyography confirmed the neuropathy was due to systemic diseases.The remaining 23 patients with recurrent CTS did not have any systemic disease and all of them had applied previously to another health center.CONCLUSION We concluded that the recurrence rates in CTS might be decreased with exploration and incision of the entire transverse ligament.Damage to the motor and sensory branches of the median nerve could be avoided with an incision on the ulnar side.
