Background:
Accurate diagnosis of carpal tunnel syndrome is key to successful treatment. At our center a treatment pathway was recently established for patients with carpal tunnel syndrome. Within this pathway patients are assessed by their community practitioner. Patients who fail to improve with conservative treatment and have a positive nerve conduction study are put forward for surgery without a specialist assessment. Recent literature has shown nerve conduction study may produce a high rate of false-positive results when used to diagnose carpal tunnel syndrome. The aim of this study was to retrospectively review outcomes of carpal tunnel decompression surgery in patients whose diagnoses was based on a community practitioner assessment and positive nerve conduction study.
Methods:
All patients who had carpal tunnel release surgery between August 1, 2017 and August 31, 2018 at our center were screened for eligibility. Data from hospital records and a standardized telephone questionnaire was used to assess surgical outcome.
Results:
The final study population included 128 operated hands. The mean follow up time after surgery was 9.6 months. We found 79% of patients reported significant improvement of their symptoms following carpal tunnel release. The overall complication rate was 2.3%.
Conclusion:
This study has demonstrated good outcomes from carpal tunnel decompressive surgery are possible in a cohort of patients whose diagnosis was made on the basis of a positive nerve conduction study and community practitioner assessment.
