Extrusion of the Hamate: A Case Report with Proposed Classification Amendment.

ABSTRACT

CASE A thirteen-year-old right-hand-dominant girl sustained a right hamate fracture-extrusion with associated pisiform dislocation and volar degloving injury with open fractures of the scaphoid, capitate, lunate, and trapezoid following an all-terrain-vehicle rollover. She was noted to have paresthesias in the median nerve distribution. Treatment involved irrigation and debridement of the right wrist and internal fixation of the hamate, capitate, and scaphoid. At fifteen months of follow-up, she had returned to competitive softball as a pitcher. Radiographs demonstrated fully healed fractures. CONCLUSION: Complete extrusion of the hamate through an open wound can be treated with good functional outcomes.
