Closed reduction and percutaneous pinning is a reliable technique for treating 2- and 3-part distal radius fractures. There are currently no data that demonstrate the proximity of at-risk nerves and tendons during percutaneous placement of 5 commonly used K-wires. Whereas the previous literature notes the risk of superficial radial nerve injury with K-wire insertion into the radial styloid, the current study provides specific distances, not only to the superficial radial nerve (SRN) but also to the tendons of the first through fifth extensor compartments during K-wire insertion. ⋯ The volar radial styloid, transverse radial, and dorsoulnar K-wires all penetrated either tendons or nerves. It is therefore prudent to make a small incision to identify and protect the underlying structures prior to placement of K-wires used for the fixation of distal radius fractures. Also, care must be taken not to place the dorsal K-wires more than 5 mm ulnar to Lister's tubercle to avoid extensor digitorum communis injury.

There are a number of insults that can compromise the soft tissue envelope of the hand. Soft tissue reconstruction seeks to restore both the aesthetic appearance and the function of the hand. The purpose of this review is to describe recent advances in hand soft tissue reconstruction. ⋯ Flaps based on donor sites from the dorsal metacarpal artery system are finding continually expanding uses in hand reconstruction. Traditional notions of forearm-based donor tissue are being challenged, leading to better hand reconstructions with less donor morbidity. Finally, improvements in free tissue transfer enable the expansion of reconstructive possibilities available for hand coverage.

Comparative Study
Comparison of loop-tendon versus end-weave methods for tendon transfer or grafting in rabbits.
The loop-tendon method for the stabilization of tendon transfers or grafts has been demonstrated previously to have greater initial tensile strength than that of the end-weave method. To our knowledge, a comparison of the mechanical strengths of these methods over the early postoperative period has not been made. The purpose of this study was to compare the mechanical strengths of loop-tendon and end-weave methods of repair during the early postoperative period in rabbit hind limb tendons. ⋯ The loop-tendon method provided greater strength than that of the end-weave method during the early postoperative period in rabbit tendons. The loop-tendon method may provide greater surgical repair strength during the early postoperative rehabilitation period than the end-weave method.

Trapezium excision with ligament reconstruction and tendon interposition has proved to be highly effective in the treatment of thumb carpometacarpal joint arthritis. Donor-site morbidity from autograft harvest can be avoided by using an allograft. We report the outcomes after suspension and interposition arthroplasty using an acellular dermal allograft (GraftJacket; Wright Medical Technology, Inc., Arlington, TN) for thumb carpometacarpal arthritis. ⋯ Therapeutic IV.

To investigate the long-term functional and clinical outcomes of a tendon transfer during basal joint interposition arthroplasty for osteoarthritis of the basal joint of the thumb, in which the origin of the abductor pollicis brevis (APB) and opponens pollicis is transferred to the flexor carpi radialis tendon, in order to increase the abduction moment arm of the thumb and provide dynamic stabilization of the base of the first metacarpal. ⋯ Therapeutic IV.
