Relationship between the duration and severity of symptoms and the outcome of carpal tunnel surgery.Burke FD, Wilgis EF, Dubin NH, Bradley MJ, Sinha S The Pulvertaft Hand Centre, Derbyshire Royal Infirmary, Derby, England. PURPOSE: There is no consensus regarding the prognostic value of preoperative symptom severity and duration for determining the anticipated results of carpal tunnel release. Some studies show a detrimental influence of symptom duration and severity on outcomes; others have found no effect. To study these contradictions, a database was created at 2 separate hand centers to explore the extent to which the duration and severity of symptoms before surgery are predictive of surgical outcome. METHODS: At 2 hand centers 523 hands from the United States and United Kingdom completed surgery and follow-up evaluation. Symptoms, time of onset, duration, prior treatment, and medical history were recorded. Each patient had a physical examination and completed the Levine-Katz questionnaire. RESULTS: Symptom duration, corrected for gender, was not associated with Levine-Katz symptom severity, Levine-Katz functional status, or changes in these scores from the pretreatment to 6-month follow-up evaluations. CONCLUSIONS: Preoperative symptom duration does not affect the surgery outcome as determined by the Levine-Katz symptom severity or functional status scores. The more severe the symptoms as determined by patient self-assessment, the greater the amount of change in the Levine-Katz symptom severity and functional status scores, although at 6 months after surgery the scores were still higher than those of patients with milder cases. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic I. Published 10 November 2006 in J Hand Surg [Am], 31(9): 1478-82.
