Article Synopsis
- - The study investigates the effectiveness of the "supercharge" end-to-side anterior interosseous nerve to ulnar motor nerve transfer in enhancing muscle recovery for patients with severe ulnar nerve damage, focusing on the first dorsal interossei and abductor digiti minimi muscles.
- - A review included 17 patients, primarily male with an average age of 55, and showed that while initial recovery in muscle action potential was limited, significant improvements were observed in muscle strength and action potential amplitudes for the abductor digiti minimi and first dorsal interossei at later follow-ups.
- - Although successful reinnervation was noted, the study concludes that the impact of targeting specific nerve fascicles during the procedure
Background: Eagle's syndrome (ES) classically describes dysphagia, globus sensation, and otalgia from an elongated and calcified styloid process or stylohyoid ligament. Compression of the spinal accessory nerve (SAN) has not been reported as an associated feature of ES or related variants.
Observations: The authors describe two cases of an atypical "winged" variant with SAN palsy resulting from compression by a posteriorly angulated or calcified styloid process.
Background: A central tenet of competency-based medical education is the formative assessment of trainees. There are currently no assessments designed to examine resident competence on-call, despite the on-call period being a significant component of residency, characterized by less direct supervision compared to daytime. The purpose of this study was to design a formative on-call assessment tool and collect valid evidence on its application.

Methods: Fourteen digits were tested using an in vitro active finger motion simulator under 3 repaired conditions following a simulated zone I avulsion: button, FDP-VP, and "no slack" FDP-VP (corrected for additional VP length). Outcome metrics included active joint range of motion (ROM), fingertip strength, FDP and flexor digitorum superficialis tensile loads, and WOF.
Purpose: To compare in vitro failure loads of nerve coaptations using fibrin glue alone, a suture alone, and a combination of fibrin glue and a suture.
Methods: The median, radial, and ulnar nerves of 15 fresh-frozen cadaveric upper extremity specimens (45 nerves in total) were dissected in vitro and transected 5 cm proximal to the wrist crease to simulate an injury requiring coaptation. Three coaptation techniques were used: fibrin glue alone, a suture alone, and a suture augmented with fibrin glue.
Purpose: The purpose of this study was to investigate the impact of repairing a zone II flexor digitorum profundus (FDP) laceration anatomically versus extra-anatomically on tendon loads and work of flexion (WOF).
Methods: Twenty digits from 5 cadaveric specimens were tested using an in vitro active finger motion simulator under 2 FDP tendon repair conditions: anatomic and extra-anatomic. Tensile loads in FDP and flexor digitorum superficialis (FDS), WOF, and total active finger range of motion (ROM) were measured using in-line load cells and electromagnetic tracking, respectively.
