Distal Biceps Brachii Tendon Transfer for Re-establishing Extrinsic Finger Function: Feasibility Study in Cadavers.

Purpose: To determine the anatomic feasibility of transferring the biceps brachii tendon into either the extensor digitorum communis (EDC) or flexor digitorum profundus (FDP), determine the excursion imparted to EDC and FDP tendons after transfer, and compare the work capacity of the cadaver biceps to previously published data on the biceps as well as the recipient muscles by calculating the physiologic cross-sectional area (PCSA).

Methods: Four fresh-frozen cadaver shoulder-elbow-wrist specimens were used to measure tendon excursion that can be obtained with transfer of the distal biceps tendon into either the EDC or FDP. Two cadavers had distal biceps-to-EDC transfer performed, and the other 2 had distal biceps-to-FDP performed.

Patient-reported outcomes after acute carpal tunnel release in patients with distal radius open reduction internal fixation.

Background: Acute carpal tunnel syndrome (CTS) is a complication that can develop after distal radius fractures. Our hypothesis tested whether patient-reported outcomes after acute carpal tunnel release (CTR) performed in combination with distal radius fracture open reduction internal fixation (ORIF) are worse than patient-reported outcomes with only elective CTR as measured by the symptom severity and functional status scales of the Boston carpal tunnel questionnaire (BCTQ).

Methods: A retrospective assessment identified 26 patients treated with acute CTR at the same time as distal radius ORIF, no history of pre-existing CTS or CTR, no other injuries, and >12 months follow-up.

Vascularized bone graft for scaphoid nonunions.

Scaphoid fracture nonunion remains a challenging problem that may persist despite traditional methods of bone grafting and internal fixation. The alteration of wrist mechanics created by nonunion as well as the development of avascular necrosis leads to degenerative change of the radiocarpal joint accompanied by loss of motion and pain. The use of a vascularized bone graft has the theoretical benefit of increased blood flow that exceeds that of nonvascularized grafts.
