Raynaud's phenomenon is a vasospastic disorder of the palmar and digital vessels of the hand and feet that can lead to ischemic ulcers, pain, and loss of function. This study is a review of patients I have injected with botulinum toxin type A for patients with Raynaud's phenomenon. ⋯ Botulinum toxin appears to improve perfusion of the hand after direct injection around the neurovascular bundles. Further investigations are warranted to identify the exact mode of action in relieving vasospasm and alleviating pain.

Randomized Controlled Trial Comparative Study
Evaluation of early postoperative pain and the effectiveness of perifracture site injections following volar plating for distal radius fractures.
Few studies have investigated the effectiveness of early postoperative pain control regimens after volar plating for distal radius fractures. This study evaluated postoperative levels of pain after volar plating of distal radius fractures under axillary nerve block in patients with and without injections of local anesthetics, narcotics, and epinephrine around the fracture site. ⋯ Therapeutic II.

Malunion of the palmar lunate facet fragment of distal radius fractures is associated with both early functional impairment and late degenerative changes. The goal of this study was to describe the clinical and radiographic outcomes after corrective osteotomy for isolated malunion of the palmar lunate facet. ⋯ Therapeutic IV.

The aim of this study was to describe and assess a surgical technique for the treatment of mallet finger fractures using a pull-out wire with K-wire stabilization of the distal interphalangeal (DIP) joint in extension. ⋯ Therapeutic IV.

Comparative Study
The effects of platelet-rich plasma on bone marrow stromal cell transplants for tendon healing in vitro.
In this study, we investigated the effect of platelet-rich plasma (PRP) and bone marrow-derived stromal cell (BMSC)-seeded interposition in an in vitro canine tendon repair model. ⋯ Platelet-rich plasma enhanced the effect of BMSC-seeded collagen gel interposition in this in vitro model. Based on these results, we now plan to investigate this effect in vivo.
