This study tested the null hypothesis that there is no difference between expected improvement and actual improvement of symptoms with carpal tunnel release (CTR). Secondary analyses addressed factors associated with both expected relief and actual relief of symptoms with carpal tunnel syndrome surgical release, predictors of arm-specific disability, and satisfaction with surgery. ⋯ Actual relief of symptoms with CTR matched patients' expectations in an employed population. Satisfaction with treatment correlated with relief of symptoms.

The distal interosseous membrane (DIOM) of the forearm acts as a secondary stabilizer of the distal radioulnar joint (DRUJ) when the dorsal and palmar radioulnar ligaments of the triangular fibrocartilage complex are cut. Recent anatomical studies revealed that thickness of the DIOM varies widely among specimens and the distal oblique bundle (DOB) exists within the DIOM in 40% of specimens. The DOB originates from the distal one-sixth of the ulnar shaft and runs distally to insert on the inferior rim of the sigmoid notch of the radius. ⋯ Ulnar shortening with the osteotomy performed proximal to the attachment of the DIOM had a more favorable effect on stability of the DRUJ compared with the effect of distal osteotomy, especially in the presence of a DOB. The longitudinal resistance to ulnar shortening was significantly greater in proximal shortening than in distal shortening. It also suggested that the DIOM is of great importance in the management of concomitant ulnar-side injuries in distal radius fracture.

Comparative Study
Biomechanical properties of fixed-angle volar distal radius plates under dynamic loading.
To evaluate and compare the biomechanical properties of 8 different locked fixed-angle volar distal radius plates under conditions designed to reflect forces seen in early fracture healing and postoperative rehabilitation. ⋯ This study provides further information to surgeons regarding the relative strengths of different plate options for the treatment of distal radius fractures.
