Observational Study
Volar plate fixation failure for volar shearing distal radius fractures with small lunate facet fragments.
To determine the percentage of AO B3 distal radius fractures that lose reduction after operative fixation and to see whether fracture morphology, patient factors, or fixation methods predict failure. We hypothesized that initial fracture displacement, amount of lunate facet available for fixation, plate position, and screw fixation would be significant risk factors for loss of reduction. ⋯ Therapeutic III.

The superficial radial nerve and its branches are vulnerable during surgery for de Quervain tenovaginitis. We studied the proximity of the nerve branches to the first extensor compartment. ⋯ The close relation of the superficial radial nerve and its lateral dorsal digital branch to the thumb with the first extensor compartment may guide surgeons during surgery for de Quervain tenovaginitis.

In patients with primary cubital tunnel syndrome, we hypothesize that using a vascularized adipose sling to secure the ulnar nerve during anterior subcutaneous transposition will lead to improved patient outcomes. The adipose flap is designed to surround the ulnar nerve with a pliable, vascularized fat envelope, mimicking the natural fatty environment of peripheral nerves. This technique may offer advantages in securing the anteriorly transposed ulnar nerve and reducing instances of postoperative perineural scarring. Patients experience good functional outcomes; most experience resolution of symptoms.

To evaluate the clinical outcome of 1,2-intercompartmental supraretinacular artery pedicled vascularized bone graft for scaphoid nonunion (SN). ⋯ Therapeutic IV.
