Involvement of the Interosseous and Lumbrical Muscle-Tendon Units in the Lateral and Spiral Cords in Dupuytren’s Disease of the Middle Fingers

BACKGROUND: The nature of intrinsic muscle involvement in Dupuytren's disease of the middle fingers (long and ring) remains poorly characterized. Over the years, the authors have observed that both the spiral and lateral digital cords in the middle fingers receive contribution from intrinsic muscle-tendon units. This report describes the anatomical characteristics and frequency of intrinsic muscle-tendon unit involvement in Dupuytren's disease …
