This study attempted to determine the safety of percutaneous release of trigger fingers, with particular attention given to border digits and the thumb. We performed percutaneous release of the A1 pulley in six fresh frozen cadaveric hands utilizing established surface landmarks. After freezing all specimens, we performed cross-sections at the A1 pulley, avoiding dissection of soft tissues, which...
Tacrolimus (FK506) is a macrolide immunosuppressive drug that is approved for the prevention of allograft rejection. It is a standard component of immunosuppressive regimens currently in use for organ and reconstructive tissue transplants. The experimental literature has demonstrated potential efficacy in the management of other diseases for which transplantation does not play a role. The ability...
Background The safety and the effects of different trajectories on thumb motion of suture-button suspensionplasty post-trapeziectomy are not known. Methods In a cadaveric model, thumb range of motion, trapeziectomy space height, and distance between the device and nerve to the first dorsal interosseous muscle (first DI) were measured for proximal and distal trajectory groups. Proximal trajectory...
Background Although pneumatic tourniquets are widely used in upper extremity surgery, further evidence is needed to support their safe use. Excessive pressure and prolonged ischemic time can cause soft-tissue injury. The purpose of this study was to determine the safety of tourniquet use in a yearlong, consecutive series of patients. Methods A retrospective review of all patients who underwent upper...
Background Collagenase clostridium histolyticum (CCH) injection for Dupuytren contracture was approved in the USA in 2010. Current FDA guidelines stipulate that finger manipulation occurs the day following injection. To investigate the safety and efficacy of delaying manipulation to 2 or 4 days following CCH injection, we conducted a prospective, randomized trial at two sites. Methods Patients with...
