Curing Finger Problems for Dummies
This 40 year old man on insulin for diabetes sustained loss of the dorsal soft tissues of his dominant index and middle fingers in a rotating blade injury. The central nail beds and central eponychial skin were partially lost, as was the dorsal DIP joint capsule and terminal tendon of the middle finger. The nail beds were reconstructed with nail bed grafts from the adjacent fingers. the middle finger terminal tendon was reconstructed with a slip of lateral band used as a graft inserted distally with a bone anchor. Dorsal flaps were elevated and partially deepithelialized, leaving distal areas undisturbed to reconstruct the undersurface of the eponychial skin fold (yellow arrows). Donor sites and flaps were closed with a full thickness skin graft from the medial proximal forearm. Nail beds were dressed with Gelfilm. |
