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.

The primary aim of our study was to investigate use of long axis computed tomography (CT) in predicting avascular necrosis of the proximal pole of the scaphoid and subsequent fracture nonunion after internal fixation. In addition, we describe a new technique of measuring the position of a scaphoid fracture and provide data on its reproducibility. ⋯ Diagnostic II.

Decision analysis is a method of probabilistic reasoning and decision-making under conditions of uncertainty. These methods are being used increasingly in hand surgery and medicine in general. ⋯ Performing a decision analysis involves (1) defining a specific question, (2) creating a model to frame the question, (3) assigning value to outcomes in the model, (4) assigning probabilities to chance events in the model, (5) identifying the best strategy within the model, (6) sensitivity analysis, and (7) model refinement. It is important to recognize the limitations inherent in decision analysis but also to understand its value in overcoming clinical uncertainty by employing a practical technique of modeling choices and outcomes.

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.

Socioeconomic pressures on medicine have redefined traditional relationships between physicians and patients, researchers and regulatory bodies, and consultants and device companies. Physicians are disheartened that the public perception of medicine, reinforced by the media, is often negative. ⋯ Although both groups have clear codes defining the ethical interaction between them, expediency and loose adherence to those guidelines has been problematic. In a climate of skepticism, the house of medicine needs to reverse and not feed that skepticism.
