Objective:
To assess the long-time results of reconstruction of the extensor pollicis longus (EPL) function by transfer of the extensor indicis (EI).
Methods:
From August 1978 to March 2003, 46 cases of loss of the EPL function were treated by transfer of the extensor indicis. Of 46 cases, there were 32 males and 14 females, aged 16-51 years with an average of 36 years; there were 24 cases of old traumatic rupture and 22 cases of secondary rupture. The disease course was 2 days to 5 months, averaged 74 days. A specific EI-EPL evaluation method (SEEM) was used to measure the EPL function after transfer.
Results:
Forty-one cases were followed up 9 years and 3 months on average (7 months to 23 years). Based on the SEEM, the results were excellent and good in 39 of 41 patients. The elevation deficit and combined flexion deficit were 0-2.2 cm (1.8 cm on average) and 0-3 cm (1.6 cm on average); the independent extension deficit was 0 degrees-8 degrees (5 degrees on average).
Conclusion:
Restoration of the extensor pollicis function by transfer of the extensor indicis is an effective and safe treatment option and the SEEM is a valid method for assessing EPL function.
