pulp space
Last reviewed 01/2018
The pulp spaces are fibrofatty compartments on the palmar side of the distal phalanx of the fingers and thumbs. They contain ramifications of the digital vessels on route to the distal phalanx - obstruction here can precipitate bone necrosis. Each space is lined and divided up by fibrous septa.
Relations:
- distal: finger tip
- proximal: distal digital flexion crease
- deep: fibrous tissue superficial to bone
- superficial: digital skin
