To biomechanically quantify 2 techniques, compression screw and perpendicular clamp, for generating compression during ulnar shortening osteotomy (USO) in order to promote reliable primary bone healing. ⋯ Larger compressive forces across the osteotomy may promote primary bone union and decrease the rates of delayed union or nonunion.

Comparative Study
Long-nerve grafts and nerve transfers demonstrate comparable outcomes for axillary nerve injuries.
To compare the functional and EMG outcomes of long-nerve grafts to nerve transfers for complete axillary nerve palsy. ⋯ Therapeutic III.

Comparative Study
Complications associated with operative versus nonsurgical treatment of distal radius fractures in patients aged 65 years and older.
To compare complication rates for distal radius fractures treated operatively versus nonsurgical in patients older than 65 years. We hypothesized that surgical intervention would improve fracture alignment, but it would be associated with more complications and equivalent functional outcomes when compared with the nonsurgical group. ⋯ Therapeutic III.

To present our experience with vascularized bone grafting based on the 1,2-intercompartmental supraretinacular artery for the management of established scaphoid nonunion and to investigate the efficacy of graft immobilization with a combination of Kirschner wires and transarticular external fixation. ⋯ Therapeutic IV.

Shift of the distal fragment of a distal radius fracture (DRF) in the coronal plane (coronal shift) may compromise the contributions of the distal oblique bundle (DOB) of the interosseous membrane to distal radioulnar joint (DRUJ) stability. The purpose of the study was to test our hypothesis that coronal shift of the distal fragment would increase dorsal-volar DRUJ displacement in response to applied load. ⋯ Awareness of the importance of coronal shift may aid in prevention of DRUJ instability associated with DRF, especially in patients with a DOB.
