Abstract
The aim of this study was to prospectively audit the results of carpal tunnel decompression using a subjective patient derived outcome score (modified Boston Symptom Severity Score) and to examine the relationship between symptom severity scores and nerve conduction studies.
Prospective cohort study of all patients undergoing open carpal tunnel decompression at Dunedin Hospital over a 13-month period from December 2003 – January 2005. Demographic details collected included age, sex, duration of symptoms, diabetes, occupation and ACC status. Pre-operative investigations consisted of nerve conduction studies and a modified version of the Boston Symptom Severity Score developed for this study. Symptom severity scores were reassessed six months post-operatively.
One hundred and ten patients participated in the study. Mean pre-operative Boston Symptom Severity Score was 3.35 (1= normal, 5=severe). Post-operatively this improved to mean 1.66, median 1.45. Ninety three percent of patients were “very satisfied” or “satisfied” with their results. Age and duration of symptoms were not significant predictors of poor outcome.
The majority of patients undergoing carpal tunnel decompression were satisfied with the outcome and had excellent or good outcomes as determined by symptom severity score. The use of preoperative nerve conduction studies help in diagnosis and prognosis.
