Palmar Radiocarpal Artery Vascularized Bone Graft for the Unstable Humpbacked Scaphoid Nonunion With an Avascular Proximal Pole.

Purpose: The most challenging scaphoid nonunion is the unstable nonunion with humpbacked collapse coupled with an avascular proximal pole. Dorsal distal radius pedicled vascularized bone grafts (VBGs) are contraindicated in cases of humpback deformity. The free medial femoral condyle VBG is an excellent option but it is an extensive microsurgical procedure with lengthy operative times and dual-limb incisions.

Fracture dislocation of the finger joints.

Fracture dislocations of the hand are difficult and often unforgiving injuries. Keys to treatment include early recognition, stable concentric reduction, and protected early active range of motion maintaining joint stability. The balance between stability and mobility is difficult to manage; therefore, surgeons need a wide array of treatments to tailor management to the specific fracture pattern.

Morphometric analysis of potential osteochondral autografts for resurfacing unicondylar defects of the proximal phalanx in PIP joint injuries.

Purpose: This study was designed to morphometrically assess the base of the little and ring finger metacarpals as potential osteochondral donors to resurface distal condylar defects of the proximal phalanx.

Methods: The proximal phalanges were dissected from all 4 fingers in 10 cadaveric hands and the following measurements were obtained from the distal condylar surface: anteroposterior height, radial-ulnar width, and radius of curvature. Measurements were obtained from posteroanterior and lateral radiographic views, which were digitized and analyzed using digital imaging software.

Hemi-hamate arthroplasty provides functional reconstruction of acute and chronic proximal interphalangeal fracture-dislocations.

Purpose: Hemi-hamate resurfacing arthroplasty is a treatment alternative for the management of severe acute and chronic dorsal proximal interphalangeal (PIP) fracture-dislocations. This study was designed to determine whether this procedure would successfully restore function after such injuries.

Methods: Hemi-hamate reconstructions were performed on 33 patients (mean age, 34 years) who presented to 1 hand surgery practice with dorsal PIP fracture-dislocations.

Fracture-dislocation about the finger joints.

Fracture-dislocations in the small joints of the fingers are challenging injuries. The surgeon must choose an appropriate treatment based on fracture pattern, joint stability, and injury chronicity. Fracture-dislocations of the proximal interphalangeal joint are notoriously unforgiving, with potential long-term sequelae of residual pain and stiffness.
