Ulnar Nerve Translocation Following a Routine Distal Radius Fracture.

A 35-year-old right hand dominant male sustained a high energy closed right distal radius fracture with associated generalized paresthesias. Following closed reduction, the patient was found to have an atypical low ulnar nerve palsy upon outpatient follow-up. After continued symptoms and an equivocal wrist MRI the patient underwent surgical exploration.

Role of Dynamic Stabilizers of the Elbow in Radiocapitellar Joint Alignment: A Prospective In Vivo Study.

Purpose: To investigate the effect of dynamic stabilizers of the elbow on radiocapitellar joint alignment, before and after the administration of regional anesthesia.

Methods: At a single institution, 14 patients were prospectively enrolled in a study using a within-subjects control design. Before performing a supraclavicular regional block, 10 fluoroscopic images (1 anteroposterior and 9 lateral views) of the elbow were obtained for each patient.

Zone 2 Flexor Tendon Repair Location and Risk of Catching on the A2 Pulley.

Purpose: To determine the region of the flexor digitorum profundus (FDP) and flexor digitorum superficialis (FDS) tendons in zone 2 that, when involved by a laceration repair, will reliably catch on the A2 pulley after surgery.

Methods: Using fresh-frozen cadavers (5 hands, 20 digits), excursions of the FDP and FDS tendons were measured in relation to the A2 pulley. The C1, A3, and C2 pulleys were resected.
