Site of insertion of flexor digitorum profundus tendon and volar plate at the distal phalanx in relation to a volar spur – A radiological-anatomical study

The volar spur at the volar base of the distal phalanx facilitates the identification of the FDP tendon attachment and its differentiation from the volar plate attachment. This may be essential in the characterization of bony volar plate avulsion in the distal phalanx. Furthermore, the volar spur may serve intraoperatively as radiological reference of the centroid of the FDP tendon attachment facilitating correct repair placement in FDP tendon avulsions.
