Description
Hung Quoc Vu and colleagues report early results of hemi-hamate arthroplasty for severe knuckle joint injuries in a 2026 case series. The operation rebuilds the broken front lip of the middle finger bone with a bone-and-cartilage graft borrowed from the hamate bone in the wrist. It is reserved for fracture-dislocations of the proximal interphalangeal joint, the finger's middle joint, where more than half the joint surface is shattered beyond ordinary repair.
Four patients treated in late 2025, all with delayed presentations, received the graft fixed with small screws, and protected active motion began within days under a splint. At three to six months the joint moved through an average arc of about eighty-two degrees, and grip strength had recovered to eighty-six percent of the uninjured side. Imaging showed every graft incorporated with the joint still aligned, and no donor-site problems appeared.
