Fractures and non-unions of the carpal scaphoid.
In the past ten to fifteen years, investigators have demonstrated conclusively that some injuries about the wrist have profound long-term consequences relative to function of the wrist. Problem fractures and non-unions of the scaphoid have been associated, in particular~ with major alterations in the kinematics of the wrist8’64. Considering its vulnerable blood supply~-4, irregular shape, pecul...
متن کاملUnions of arcs from Fourier partial sums
Elementary complex analysis and Hilbert space methods show that a union of at most n arcs on the circle is uniquely determined by the nth Fourier partial sum of its characteristic function. The endpoints of the arcs can be recovered from the coefficients appearing in the partial sum by solving two polynomial equations.
متن کاملScaphoid excision with four-corner fusion: a biomechanical study.
PURPOSE Partial wrist arthrodesis is a commonly performed procedure for the treatment of posttraumatic wrist arthritis because of its ability to provide pain relief without sacrificing complete wrist motion. The purpose of this study was to evaluate the redistribution of force after four-corner fusion and scaphoid excision, and to correlate the findings with the reported clinical outcomes. ME...
متن کاملHuman scaphoid non‐unions exhibit increased osteoclast activity compared to adjacent cancellous bone
Scaphoid bones have a high prevalence for non-union. Even with adequate treatment, bone regeneration may not occur in certain instances. Although this condition is well described, the molecular pathology of scaphoid non-unions is still poorly defined. In this study, gene expression of osteogenic and angiogenic growth and transcription factors as well as inflammatory mediators were analysed in h...
متن کاملBiomechanical Consequences of Coracoclavicular Reconstruction Techniques on Clavicle Strength
BACKGROUND Lateral clavicle fractures have been reported after coracoclavicular (CC) ligament reconstructions with bone tunnels through the clavicle. PURPOSE To biomechanically compare clavicle strength following 2 common CC reconstruction techniques with different bone tunnel diameters. STUDY DESIGN Controlled laboratory study. METHODS Testing was performed on 2 groups of matched-pair ca...
