Outcome of vascularised muscle pedicle bone graft for scaphoid non-union

Abstract

<p class="abstract"><strong>Background:</strong> The objective of the study was to assess the <span lang="EN-IN">outcome of vascularised muscle pedicle bone graft for scaphoid non-union.</span></p><p class="abstract"><strong>Methods:</strong> <span lang="EN-IN">14 men and 6 women aged 18-45 (mean 25) years with non-union of scaphoid involving proximal pole (n=4), waist (n=14), distal pole (n=2) were randomized to undergo vascularised muscle pedicle bone graft with Herbert screw fixation. The mean duration of non-union was 10 months (range 4-14 months)</span>.<strong></strong></p><p class="abstract"><strong>Results:</strong> <span lang="EN-IN">The mean follow up duration was 24 months. 17 of 20 achieved union. 12 of 20 achieved correction of both scapholunate and radiolunate angle. 5 of 20 did not achieve full correction of sacpholunate and radiolunate angle. 3 of 20 did not achieve union. 2 of these 3 were associated with proximal pole absorption. There was no hardware failure or any iatrogenic fracture during pedicle dissection. </span></p><p class="abstract"><strong>Conclusions:</strong> <span lang="EN-IN">The use of vascularised bone graft has proved to be an effective method for treating scaphoid non-union, especially non-union with an avascular proximal pole and those that have failed to heal after previous procedure.</span></p>
