A Proposal for a Standardized Nomenclature of the C-arm Movements.

Unlabelled: No formal didactic source exists concerning terminology for movement of the C-arm in the operating room (OR). Many terminologies exist, breeding confusion among OR staff. The objective of this study was to survey the existing C-arm movement terminologies among orthopaedic surgeons and radiologic technologists and propose a standardized nomenclature moving forward.

Distal triceps transosseous cruciate versus suture anchor repair using equal constructs: a biomechanical comparison.

Background/hypothesis: Suture anchor-based repair has been advocated for repair of distal triceps avulsion, but previous models have used an unequal number of sutures across the repair site. We hypothesized that there would be no difference in triceps tendon displacement between gold standard repair with transosseous cruciate bone tunnels and suture anchor repair with an equal number of sutures in the constructs.

Methods: The triceps tendon footprint was measured in 20 cadaveric elbows (10 matched pairs), and a distal triceps tendon rupture was created.

Distal fibular malrotation and lateral ankle contact characteristics.

Background: Any amount of malreduction of the syndesmotic joint compared with the uninjured syndesmosis has been associated with an adverse effect on functional outcome. The amount of malrotation that may lead to clinically relevant pressure change in this joint has not been reported. Our purpose was to determine whether small degrees of external and internal malrotation would be associated with statistically significant changes in contact pressure in the tibiofibular and talofibular articulations.

Treatment of a Pediatric T-type Intercondylar Humerus Fracture With Hybrid Percutaneous Pinning and External Fixation.

T-type intercondylar fractures of the distal humerus are rare injuries in skeletally immature patients. Few studies are available to guide the treatment of these injuries. Small case series and expert recommendations suggest superiority of the open approach for direct reduction of the articular surface.
