We investigated prognostic factors of patients who lack a preoperative compound muscle action potential (CMAP) of the abductor pollicis brevis (APB) muscle to determine the necessity for single\u2010stage opponensplasty.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We retrospectively enrolled 22 hands of 22 CTS patients. Prognostic factors considered were age, diabetes mellitus, the median sensory nerve action potential, distal motor latency of the second lumbrical (2L) CMAP (2L\u2010DML), and its amplitude (2L\u2010Amp). Postoperative APB\u2010CMAP amplitude (post APB\u2010Amp) at 12 months was used as the outcome measure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Only 2L\u2010DML showed a significant correlation with post APB\u2010Amp (r = \u20100.56). The contribution of 2L\u2010Amp was not significant, although 3 hands with absent 2L\u2010CMAP had a poor electrophysiological recovery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Prolonged 2L\u2010DML and absent 2L\u2010CMAP seem to be poor prognostic factors.
