title: Clinical outcomes of endoscopic carpal tunnel release in patients 65 and over.
abstract: OBJECTIVE
  To examine outcomes of endoscopic carpal tunnel release (ECTR) in patients 65 and older. We hypothesized that this population could expect relief of pain, night pain/numbness, and numbness.
  
  
  METHODS
  A retrospective review was conducted of all patients 65 years of age and over who had ECTR for nerve conduction study-confirmed carpal tunnel syndrome (CTS) from October 2007 to July 2010. The charts were reviewed for demographic data, symptoms and physical findings, patient satisfaction, and 3 patient-reported outcome scores. Preoperative and postoperative results for pain, night pain/numbness, and numbness were compared. Logistic regression analysis was used to assess whether age influenced symptom resolution. Boston carpal tunnel, Short Form-36 and Disabilities of the Arm, Shoulder, and Hand scores were compared between patients with mild, moderate, or severe CTS.
  
  
  RESULTS
  A total of 78 patients had ECTR. Their ages ranged from 65 to 93 years (mean, 73 y). Before surgery 69% of patients had constant numbness. Night pain/numbness was present in 65 patients before surgery, and 61 had complete resolution. All 70 patients who presented with pain reported complete relief by the 6-month follow-up. Following ECTR, the average Boston carpal tunnel symptom severity, functional status, and Disabilities of the Arm, Shoulder, and Hand scores were 1.5,1.5, and 13, respectively. At final evaluation, 79% of patients were very satisfied or satisfied with their outcome. A significant number of patients were found to have improvement in pain, night pain/numbness, and numbness following ECTR.
  
  
  CONCLUSIONS
  This study has demonstrated relief of symptoms in a statistically significant number of patients following ECTR. We found that preoperative CTS severity, based on nerve conduction study result, did not significantly correlate with patient outcome following ECTR. Advanced symptoms at presentation do not preclude symptom resolution and should not be a contraindication to ECTR.
