Randomized Controlled Trial Comparative Study
A prospective randomized controlled trial of injection of dexamethasone versus triamcinolone for idiopathic trigger finger.
This study was designed to test the null hypothesis that there is no difference in resolution of triggering 3 months after injection with either a soluble (dexamethasone) or insoluble (triamcinolone) corticosteroid for idiopathic trigger finger. ⋯ Although there were no differences 3 months after injection, our data suggest that triamcinolone may have a more rapid but ultimately less durable effect on idiopathic trigger finger than does dexamethasone.

Midcarpal degeneration is well documented after radioscapholunate fusion. This study tested the hypothesis that radioscapholunate fusion alters the kinematic behavior of the remaining lunotriquetral and midcarpal joints, with specific focus on the dart-thrower's motion. ⋯ Simulated radioscapholunate fusion altered midcarpal and lunotriquetral kinematics. The increased rotations across these remaining joints provide one potential explanation for midcarpal degeneration after radioscapholunate fusion. Additionally, this fusion model confirms the dart-thrower's hypothesis, as wrist motion after simulated radioscapholunate fusion was primarily preserved from radial-extension toward ulnar-flexion.
