Pedicled Vascularized Bone Graft of the Distal Radius for Recalcitrant Nonunion of the Distal Humerus.

Objectives: To analyze the clinical and radiological outcomes of a series of patients treated with a pedicled vascularized bone graft (VBG) of the distal radius for the treatment of recalcitrant atrophic nonunions of the distal humerus.

Design: Retrospective clinical study.

Setting: University-affiliated teaching hospital.

Innervation of the Proximal Interphalangeal Joint: An Anatomical Study.

Purpose: To describe the innervation of the proximal interphalangeal (PIP) joint of the fingers as well as the anatomical relations of the articular branches.

Methods: In this anatomical study, 52 fresh-frozen index, long, ring, and little fingers of 6 male and 4 female cadavers were dissected after injection of a colored latex composite. The anatomical dissections were performed under ×3.

Extended Posterior Interosseous Artery Flap: Anatomical and Clinical Study.

Purpose: A reverse-flow pedicled flap from the posterior interosseous artery (PIA) has been used to cover defects on the dorsal and volar aspects of the hand. However, the original description of this flap does not reach further than the metacarpophalangeal joints of the 4 ulnar digits. In the present study, we describe a distal variant (type 2) of the PIA flap, which changes the pivot point of the classic variant (type 1) and which can provide full coverage of single or multiple digits in the entire dorsum and palmar surface of the fingers.
