Midterm Outcome of Bone-Ligament-Bone Graft and Dorsal Capsulodesis for Chronic Scapholunate Instability.

Purpose: To assess midterm outcomes of our bone-ligament-bone (BLB) grafts for chronic scapholunate (SL) instability and better define criteria for their use.

Methods: We conducted a retrospective review of 26 patients treated with BLB grafts and dorsal capsulodesis between 1997 and 2009. Twenty-four patients were reviewed.

Variations in glial cell line-derived neurotrophic factor release from biodegradable nerve conduits modify the rate of functional motor recovery after rat primary nerve repairs.

Accelerating axonal regeneration to shorten the delay of reinnervation and improve functional recovery after a peripheral nerve lesion is a clinical demand and an experimental challenge. We developed a resorbable nerve conduit (NC) for controlled release of glial cell line-derived neurotrophic factor (GDNF) with the aim of assessing motor functional recovery according to the release kinetics of this factor in a short gap model. Different types of resorbable NCs were manufactured from a collagen tube and multiple coating layers of poly(lactide-coglycolide), varying in poly(lactide-coglycolide) type and coating thickness to afford three distinct release kinetics of the neurotrophic factor.

Accessory extensor pollicis longus.

Phylogenetically the accessory extensor pollicis longus in man seems to find its origin in the deep extensor layer, and this has largely been described in primates. I describe a case and present a comprehensive review of other publications on the subject.

A mechanical comparison of bone-ligament-bone autografts from the wrist for replacement of the scapholunate ligament.

A study was performed to compare the mechanical properties of two intracarpal ligaments with those of the dorsal component of the scapholunate interosseous ligament (SLIL). Trapezoid-to-second metacarpal, capitate-to-trapezoid ligaments, and the dorsal part of the SLIL were obtained as bone-ligament-bone grafts from fresh frozen cadavers. Their respective load to failure and stiffness were measured under uniaxial load on a servohydraulic machine and compared.
