All Preparations. All Approaches. The base of the distal phalanx has a prominent dorsal crest at the insertion of the extensor tendon.
A year-old right-hand-dominant man sustained an avulsion injury to his right thumb while operating a rotating chain machine, resulting in a full-thickness traumatic defect of the volar aspect of the distal thumb measuring 7 cm 2 Fig 1. The distal volar thumb soft tissue is composed of a thick epidermis with deep papillary ridges, below which lies fibrofatty tissue stabilized by fibrous septa that extend from the periosteum of the distal phalanx to the dermis. The goals of reconstruction are to restore functional length of the thumb, provide robust coverage and sensibility, prevent contracture, and strive for the best cosmetic outcome.

When we think of our ability to bear down on small holds, we usually think of tendon strength. The more "pulp" between your bone and your skin, the better you can crimp. The study found that meatier tips are an advantage for crimping.
A year-old woman had become aware of a mass on the palmar aspect of the distal phalanx of her left thumb 11 years earlier. Her medical history was unremarkable, with no traumatic injury of the left thumb. No pain, sensory disturbance, or motor dysfunction was noted.

Archives of Orthopaedic and Trauma Surgery. In this report, we present the functional and cosmetic results of a case with complete loss of the thumb pulp for which the Chen and Noordhoof techniques has been chosen for reconstruction. A year-old man, artisan, had his right thumb caught in a machine during the work, resulting in a degloving injury in the entire pulp of the distal phalanx of the thumb with all other digits of the right hand intact.
