Restoration of extensor pollicis longus function by tendon transfer.

L H Schneider, R G Rosenstein

    Plastic and Reconstructive Surgery
    |April 1, 1983
    PubMed
    Summary

    Transferring the extensor indicis proprius tendon effectively restored thumb extension in most patients with chronic extensor pollicis longus loss. This surgical technique shows high success rates for thumb extensor function recovery.

    Area of Science:

    • Hand surgery
    • Orthopedic surgery
    • Reconstructive surgery

    Background:

    • Chronic loss of the extensor pollicis longus (EPL) significantly impairs thumb function.
    • Restoring EPL function is crucial for overall hand dexterity and daily activities.

    Purpose of the Study:

    • To evaluate the efficacy of transferring the extensor indicis proprius (EIP) tendon for chronic EPL loss.
    • To assess the functional recovery and complication rates associated with EIP tendon transfer.

    Main Methods:

    • The study involved 28 patients with chronic EPL loss who underwent EIP tendon transfer.
    • Patient outcomes were assessed at intervals ranging from 4 months to 5 years post-surgery.

    Main Results:

    • Excellent recovery of long thumb extensor function was observed in 82% (23 out of 28) of patients.

  • Nine patients experienced a loss of up to 30 degrees of interphalangeal joint flexion.
  • Two cases (7%) were considered failures, and two patients were lost to follow-up. One reattachment was successful after rupture.

    • Conclusions:

    • Transfer of the extensor indicis proprius is a highly effective surgical option for restoring thumb extensor function in cases of chronic extensor pollicis longus loss.
    • The procedure demonstrates a favorable success rate with minimal complications related to tendon removal from the index finger.
