What Is the Effect of the Ulnar-Plus Variance on the Outcomes of Arthroscopic Repair of the Peripheral Ulnar-Side Triangular Fibrocartilage Complex Tear?

Purpose: To compare the outcomes of arthroscopic repair of peripheral ulnar-side triangular fibrocartilage complex (TFCC) tears between patients with and without ulnar-plus variance (UPV) and to identify factors associated with index surgery failure in these patients.

Methods: We retrospectively analyzed 50 consecutive patients who underwent arthroscopic repair of peripheral ulnar-side TFCC tears from June 2014 to February 2018. We selected patients who were aged at least 18 years and underwent arthroscopic repair of peripheral ulnar-side TFCC tears.

Does use of the 70° arthroscope improve the outcomes of arthroscopic débridement for chronic recalcitrant tennis elbow?

Background: The use of a 70° arthroscope has been reported to provide better visualization of the extensor carpi radialis brevis origin at the lateral epicondyle. We aimed to compare the surgical outcomes of arthroscopic débridement using an additional 70° arthroscope with those using a 30° arthroscope alone in the treatment of chronic recalcitrant tennis elbow.

Methods: A total of 68 consecutive patients who received arthroscopic débridement for chronic recalcitrant tennis elbow were retrospectively reviewed.

Morphometric Variations in the Volar Aspect of the Distal Radius.

Background: Significant discrepancy exists between anatomical plate designs and the anatomy of the native distal radius, which may be attributable to considerable morphometric variations in the volar aspect of the distal radius. We aimed to evaluate the degree of variability in the morphometry of the distal radius and identify factors associated with this variability.

Methods: We measured the volar surface angle (VSA) of the intermediate and lateral columns and the volar surface width (VSW) in the distal radius from three-dimensional computed tomography scans acquired from 81 cadaveric forearms.

What is the Natural History of the Triangular Fibrocartilage Complex Tear Without Distal Radioulnar Joint Instability?

Background: The triangular fibrocartilage complex (TFCC) tear is a common cause of ulnar-side wrist pain; however, its natural course is not well understood.

Questions/purposes: We sought (1) to determine the natural course of TFCC tears without distal radioulnar joint (DRUJ) instability, and (2) to identify the factors associated with poor prognosis after nonsurgical treatment of TFCC tears.

Methods: Over a 3-year period, we treated 117 patients with TFCC tears who did not have DRUJ instability.

Dopa responsive slow orthostatic tremor in Parkinson's disease.

Slow orthostatic tremor (OT) occurred to longer and lower frequency regular rhythmic bursts in leg muscle upon standing. The slow OT was often able to clinically confused with orthostatic myoclonus. We described a Parkinson's disease patient with levodopa responsive slow OT.
