title: Arthrodesis of the first metatarsophalangeal joint: a retrospective analysis of plate versus screw fixation.
abstract: Arthrodesis of the first metatarsophalangeal joint is a commonly accepted technique to treat various afflictions of the hallux. Many techniques have been described to fixate the arthrodesis. However, no superior fixation technique has been identified in regard to nonunion. We performed a retrospective analysis of first metatarsophalangeal joint arthrodeses in our clinic from January 2000 to April 2010, focusing on plate and screw fixation. Our aim was to identify the best fixation construct in regard to fusion rates and radiologic nonunion. We identified 72 arthrodeses performed using 1 oblique (n = 24) or 2 crossed (n = 21) lag screws or a plate (n = 13) or a plate augmented with plantar lag screw fixation (n = 14). Our analysis showed that plate fixation alone results in significantly fewer nonunions than single screw fixation. A comparison of the other fixation types showed no significant differences with regard to nonunion. Although our analysis showed that plate fixation alone is superior to single screw fixation, no definitive conclusion can be drawn owing to methodologic shortcomings. We believe a randomized controlled trial with larger sample sizes is necessary to find the clinically superior fixation technique.
