Electrodiagnostic Grade and Carpal Tunnel Release Outcomes: A Prospective Analysis

Area of Science:

• Orthopedics
• Neurology
• Surgical Outcomes Research

Background:

• Carpal tunnel release (CTR) is a common surgical procedure.
• The prognostic value of electrodiagnostic (EDX) study grades for predicting clinical outcomes after CTR is debated.

Purpose of the Study:

• To determine if symptom relief after CTR differs based on preoperative electrodiagnostic (EDX) grade.
• To assess postoperative symptomatic and functional improvement in relation to EDX severity.

Main Methods:

• Prospective evaluation of 199 patients undergoing CTR (256 hands).
• Data collection included demographics, EDX grade (mild, moderate, severe), surgical parameters, and validated questionnaires (Quick-DASH, symptom/functional status, pain scales).
• Follow-up at 2 weeks and 3 months post-surgery.

Main Results:

• Significant improvements in Quick-DASH, symptom severity, and functional status scores were observed across all EDX grades.
• No significant differences in recovery extent were found based on preoperative EDX grade at 2 weeks or 3 months.
• Pain significantly decreased by 2 weeks post-surgery, with sustained improvement regardless of EDX grade.

Conclusions:

• CTR yields consistent, significant improvements in patient outcomes irrespective of the preoperative electrodiagnostic (EDX) severity.
• The degree of postoperative improvement after CTR is not statistically different among EDX grade groups.
• Older patients with severe carpal tunnel syndrome (CTS) may experience more moderate gains.
