Scaphoid Nonunions Treated with Nonvascularized Bone Grafting and Screw Fixation.

 Vascularized bone grafting with screw fixation is currently considered the treatment of choice for scaphoid nonunions with avascular necrosis (AVN) of the proximal pole. A viable alternative to using vascularized bone grafts for scaphoid nonunions with AVN is nonvascularized bone grafting with screw fixation.  What are the functional outcomes of patients with scaphoid nonunions and associated proximal pole AVN who are treated with nonvascularized distal radius bone grafting and screw fixation?  Eight scaphoid nonunions with AVN, which received nonvascularized distal radius bone graft and screw fixation, underwent a retrospective review.

Electrodiagnostic Evidence of Berrettini Anastomosis.

Purpose: Cadaveric palmar dissections reveal an ulnar sensory crossover (Berrettini anastomosis) to the third common palmar nerve so frequently that this crossover is considered a normal part of the anatomy. No literature has documented electrophysiologic evidence of the Berrettini anastomosis (BA). Presentation of third digit ulnar sensory crossover waveforms.

Prevention of Tendon Subluxation in Dequervain's Tenosynovitis Release Using Retinacular Repair.

This study compared the incidence of tendon subluxation in patients of a single surgeon undergoing Dequervain's release with and without retinacular repair. The study reviewed 31 patients that underwent standard Dequervain's release without retinacular repair and 49 that underwent Dequervain's release with retinacular repair. Each subject's functional status was assessed using the Patient-Rated Wrist/Hand Evaluation.
