Abstract
This study examined the resolution of symptoms, functional limitations and neuromuscular impairments following carpal tunnel release. Thirty-five patients were evaluated preoperatively and 6 weeks, 3 months, 6 months, and a mean of 27 months postoperatively. Evaluation consisted of physical examination (performed in a subset of patients) and previously validated questionnaire scales measuring symptoms, functional limitations, and satisfaction. Nocturnal pain, tingling, and numbness improved within 6 weeks after surgery. Weakness and functional status improved more gradually. Grip and pinch strength worsened initially, returned to pre-operative levels after about 3 months, and improved significantly by 24 months. The Tinel and Phalen signs remained positive in two and seven patients, respectively, after 2 years, and two-point discrimination remained abnormal in over half of patients after 2 years. These temporal patterns should be discussed with patients to foster realistic expectations of the response to surgery.
