Comparative Study
An anatomical basis for endoscopic cubital tunnel release and associated clinical outcomes.
To study the ulnar nerve in fresh-frozen cadavers as related to endoscopic release of the cubital tunnel and to present a retrospective review of patients treated with decompression via endoscopic visualization. ⋯ Therapeutic IV.
-
To evaluate union and complication rates associated with the use of 2 headless compression screws and bone grafting for the treatment of scaphoid nonunions. ⋯ Therapeutic IV.

Observational Study
Measurement of upper extremity disability using the Patient-Reported Outcomes Measurement Information System.
Current questionnaires used to measure upper extremity-specific disability can be time-consuming and subject to ceiling effects. The National Institutes of Health developed Patient-Reported Outcomes Measurement Information System (PROMIS) measures based on computer adaptive testing (CAT), a technique that is more efficient and less subject to floor and ceiling effects than traditional questionnaires with a fixed number of questions. This study tested the correlation of the Physical Function-Upper Extremity CAT with the Quick-Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire. ⋯ Prognostic I.

To investigate the course and variability of the radial nerve along the lateral humerus in relation to the center of rotation of the elbow joint in the context of lateral pin placement for hinged external fixation. ⋯ Based on this cadaveric study, it is not possible to define a rational safe zone. The safest method of pin application for dynamic external fixation of the elbow is to perform a mini-open dissection with direct visualization.
