PURPOSE: Deformity of the digital web space is commonly encountered and can be congenital or acquired. Its correction requires an understanding normal anatomy, which poorly understood, understudied. The challenge to re-create a in appearance function are equally difficult. purpose this study introduce previously unreported ligamentous structures space. METHODS: Forty spaces were microsurgically dissected twenty cadaveric hands. Select H&E, Trichrome Elastin stains obtained. Anatomic observations made correlated with intraoperative findings as they relate burn reconstruction syndactylies. RESULTS: Formed by relatively large, three-dimensional inclined triangle extending from distal palm dorsal metacarpophalangeal joint, its functional demands completely interdependent. dynamically changing planes contours result complex subcutaneous endoskeleton consisting dense fibrous attachments between palmar skin along whole length width into fingers continuity Cleland's Grayson's ligaments. These tethers so strong that one lift hand up holding onto them, yet flexible enough allow for finger abduction adduction. CONCLUSION: webspace more than fat. A newly described framework defines shape function. We will discuss importance preserving re-creating significance management deformities.
