The memory plate for four-corner fusion of scaphoid non-union advanced collapse

The aim of this study was to evaluate the clinical outcomes of the memory plates for four-corner fusion (FCF) of scaphoid non-union advanced collapse (SNAC). From 2005-2010, 11 cases of SNAC received FCF with the memory plate designed by the authors. At an average follow-up of 21 months, there were no non-unions and postoperative infections. One patient complained of dorsal impingement. The pain relief rate was 100% and the average grip strength increased from 11.3% preoperatively to 56.3% postoperatively of the contralateral side. The primary results of FCF with memory plates are promising. By its compressive property, the memory plate facilitates the arthrodesis with a lower complication rate.
