Endoscopic Carpal Tunnel Release in the Elderly

Abstract

The present study is aimed to clarify the postoperative outcome of endoscopic carpal tunnel release in elderly patients with carpal tunnel syndrome. Endoscopic carpal tunnel release was performed on 37 hands of 27 patients (2 men, 25 women) who were aged 70 years or older and clinically and electrophysiologically diagnosed with carpal tunnel syndrome. Mean age at the time of surgery was 74.5 years (range: 70-85 years). Mean postoperative follow-up was 35.5 months (range: 12-114 months). Pain was present preoperatively in 20 hands, but quickly resolved postoperatively in all cases. Numbness completely disappeared in 13 of 37 hands (35.1%), but some degree of numbness remained in the remaining cases. Preoperative severity of thenar muscle atrophy was none in 4 hands, mild in 7 hands, moderate in 12 hands and severe in 14 hands. Postoperative severity of thenar muscle atrophy at final follow-up was none in 13 hands, mild in 16 hands, moderate in 2 hands and severe in 6 hands, confirming that thenar muscle atrophy improves even in elderly patients. However, moderate or severe thenar muscle atrophy remained in 8 hands (21.6%). Endoscopic carpal tunnel release should be considered in the elderly, even though clinical symptoms may not improve substantially in advanced cases.
