Arthordesis of small joints of the foot is a commonly performed procedure in orthopaedics. A variety of fixation devices have been used for this purpose. Nickel-Titanium Memory compression staples for arthrodesis have been used in our institute since June 2003. We report the results of the procedure over a period of 7years involving 252 feet in 232 consecutive patients who underwent arthrodesis or an osteotomy fixation using compression staples. The patients were evaluated to determine the period of immobilization in cast and the time to radiographic joint fusion. The emphasis of this study was to validate the safety of the implant for fusion of small joints of the foot, as well as to determine whether there is a demonstrable trend in time to fusion and period of immobilization required. The average time to fusion was 7.2 weeks, the average period of immobilisation was 6.5 weeks. Successful union was achieved in 98% cases. We report the follow up results, finer technical aspects of the procedure and pitfalls to avoid whilst performing the fusions.
Controversy persists regarding preference between Herbert and Acutrak screw for internal fixation of scaphoid non-union. Acutrak screw has been shown to have better biomechanical compression properties than Herbert screw in the laboratory setting. The aim of this study was to assess the clinical, radiological and functional outcome of patients treated with the two different screw systems. A retrospective review of the results of patients with scaphoid non-union treated by a single surgeon. Group 1 comprised of 61 patients treated with Herbert screw between July1996 and June2000 and Group 2 comprised of 71 patients treated with Acutrak screw between July 2000 and December 2005. Union rates were assessed radiologically and clinically. Functional outcome was measured by using modified Mayo wrist score.Background
