Comparative Study
Using Hounsfield Units to Assess Osteoporotic Status on Wrist Computed Tomography Scans: Comparison With Dual Energy X-Ray Absorptiometry.
Rates of evaluation and treatment for osteoporosis following distal radius fragility fractures remain low. As a subset of patients with these fractures undergo diagnostic computed tomography (CT) scan of the wrist, utilizing bone mineral density (BMD) measurements available with this imaging can be used to detect osteopenia or osteoporosis. This information may consequently prompt intervention to prevent a subsequent fracture. The purpose of this study was to determine if Hounsfield unit (HU) measurements at the wrist correlate with BMD measurements of the hip, femoral neck, and lumbar spine and to assess the ability of these HU measurements to detect osteoporosis of the hip. ⋯ Diagnostic III.

Trigger finger is the most common entrapment tendinopathy, with a lifetime risk of 2% to 3%. Open surgical release of the flexor tendon sheath is a commonly performed procedure associated with a high rate of success. Despite reported success rates of over 94%, percutaneous trigger finger release (PFTR) remains a controversial procedure because of the risk of iatrogenic digital neurovascular injury. This study aimed to evaluate the safety and efficacy of traditional percutaneous and ultrasound (US)-guided first annular (A1) pulley releases performed on a perfused cadaveric model. ⋯ Our cadaveric data align with those of published clinical investigations for percutaneous A1 pulley release.

The currently available phalangeal external fixators are either commercial and not universally available or made of Kirschner wires and a linkage mechanism such as rubber bands and cement. They are difficult to assemble and difficult to adjust after application. This paper presents an external fixator made of Kirschner wires and locking balls (better known by their commercial name: Jurgan Balls) that is easily assembled on demand in the operating room. ⋯ It does not require the use of cement or rubber bands. It allows adjustment during surgery and maintains the reduction throughout the postoperative period. It may be a useful tool for open and/or highly comminuted fractures and fracture subluxations of the proximal and middle phalanges as well as the thumb metacarpal.

We sought to evaluate the clinical and radiographic outcomes after treatment of symptomatic, recalcitrant scaphoid nonunions using a novel combination of volar scaphoid buttress plating with a pedicled vascularized bone graft. ⋯ Therapeutic IV.
