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.

Comparative Study
The Effect of Debridement of Coexisting Partial Ligament Injuries on Outcomes Following Arthroscopic Osteosynthesis for Minimally Displaced Scaphoid Nonunions.
Partial intercarpal ligament injuries can coexist with scaphoid nonunions. However, whether these injuries should be debrided simultaneously when scaphoid nonunions are treated is unclear. The purpose of this study was to compare union rates and clinical outcomes after arthroscopic management of scaphoid nonunions, in which coexisting partial ligament injuries were, or were not, simultaneously debrided. ⋯ Therapeutic III.

Comparative Study
Biomechanical Comparison of Bicortical, Unicortical, and Unicortical Far-Cortex-Abutting Screw Fixations in Plated Comminuted Midshaft Clavicle Fractures.
The objective of this study was to assess the biomechanical properties of bicortical locking screws, unicortical locking screws, and unicortical far-cortex-abutting locking screw fixation in a cadaver model of comminuted midshaft clavicle fractures stabilized with a locking plate placed on the superior surface of the clavicle. ⋯ Unicortical far-cortex-abutting locking screw fixation obviates far cortex penetration, and thereby protects nearby anatomical structures, may ease symptomatic implant removal, alleviates refracture risk, and eases conversion to bicortical fixation in the case of revision surgery.
