Outcomes of radial head arthoplasty following mason III and IV radial head fractures

摘要

Aims: This study reports a comparison of non-union rates of the 1stmetatarsophalangeal joint (MTPJ) with the current Memometal AnchorageTM dorsal plate system used at our Trust, and the previously used HallufixTM and CharlotteTM systems. The objectives of the study are to demonstrate whether or not patient outcome has been improved after changingpractice to use the Memometal AnchorageTM system.Methods: Between 01/2009 and 07/2012 174 consecutive 1st MTPJ fusionswere performed for 153 patients (Mean age 62, range 42 to 83) by threesurgeons at one University teaching hospital. 40 patients (23%) were maleand 132 (77%) female. 20 patients received Hallu-fixTM plates, 76 CharlotteTM plates and 76 Memometal AnchorageTM plates. Radiographs of thefeet were taken four weeks postoperatively and reviewed for signs of nonunion. Ratios of failure rates between plates were compared using Fisher'sexact tests (p ? 0.05).
