Abstract:
Volar lip fractures of the base of the proximal interphalangeal
joint (PIPJ) are triggered by axial loading and hyperextension
injuries causing the volar plate to avulse with a ventral
fragment of the base of the middle phalanx [1]. These
fractures are commonly encountered during athletics and
combat sports [1]. If more than 50% of the joint surface is
involved, it is considered an unstable fracture [2].
Osteochondral grafts are preferably used to treat unstable
fracture-dislocations [2]. Moreover, grafting is preferred in
late presenters [3] compared to those who present early, where
the fracture could be fixed with a higher success rate. Here, we
report two cases of ventral fractures of the PIPJ managed with
hemi-hamate osteochondral autografts.
