Abstract
The outcome of carpal tunnel release was evaluated retrospectively in 60 hands of 53 patients followed for six to 33 months (median ten months). Outcome was considered good in 27% (pain, weakness, and numbness were essentially resolved); fair in 42% (most of the symptoms improved); and poor in 32% (symptoms persisted or worsened). Patients whose pre-operative work activity was considered physically strenuous were associated with a slightly but significantly poorer outcome (60% good or fair) compared to those in light work or with no employment (89% good or fair). Proportionately fewer patients returned to their original work when they previously engaged in strenuous activity, ranging from 27% for those using air guns to 80% in light work. It appears that the highest chance of a poor outcome from carpal tunnel release occurs in patients who have either associated symptoms of thoracic outlet syndrome or physically strenuous work activities.
