Yu-G-Z. Firrell-J-C. Tsai-T-M. J-Hand-Surg-[Br]. 1992 Dec. 17(6). P 646-50. 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.
