To evaluate the feasibility of restoring the deltoid function in patients with C5 through C7 root avulsion injuries by transferring 2 intercostal nerves to the anterior branch of the axillary nerve through a posterior approach. The preliminary results of the clinical application of this procedure also are reported. ⋯ Therapeutic IV.

Comparative Study
Biomechanical comparison of fixed-angle volar plate versus fixed-angle volar plate plus fragment-specific fixation in a cadaveric distal radius fracture model.
To test the hypothesis that combining orthogonal fragment-specific fixation with volar fixed-angle fixation provides markedly higher interfragment stability and construct strength compared with volar fixed-angle fixation alone. ⋯ In a simulated cadaveric model of the distal radius intra-articular fracture, the combined technique of fragment-specific plating with volar fixed-angle fixation alone provides superior biomechanical strength and stability over the volar fixed-angle fixation alone.

To investigate if early controlled passive mobilization was likely to cause harm with regard to affecting the quality and rate of early fracture healing in a closed, potentially unstable, diaphyseal fracture in a rabbit model. ⋯ During the initial 28 days after the fracture, in this simulated hand, closed, potentially unstable, extra-articular fracture, the early controlled passive motion protocol used in this study led to a clinical and statistical significant reduction in fracture dorsal angulation and improvement in the fracture's ability to resist and bear 4-point bending loads without increasing the total callus area. Therefore, early controlled passive mobilization after a closed, potentially unstable, diaphyseal hand fracture warrants further clinical consideration.
