title: Dual plating with bone block arthrodesis of the first metatarsophalangeal joint: A clinical retrospective review.
abstract: BACKGROUND
  First metatarsal phalangeal joint (MTP) arthrodesis is challenging in the setting of bone loss. The purpose of this study was to describe the results of interpositional grafting and arthrodesis of the first MTP joint using two plates in a 90/90 configuration.
  
  
  METHODS
  Eleven patients had an MTP arthrodesis with 90-90 plating with an interpositional allograft. We analyzed the fusion rate, restoration of first ray length, patient satisfaction, and complication rates.
  
  
  RESULTS
  The overall union rate was 90.9%, with an average restoration of 11 ± 4.5mm in length to the first ray. The average time to fusion was 10.7 ± 1 weeks. The mean preoperative AOFAS score improved significantly. The complication rate was 18.2% and included one superficial wound infection and one non-union who underwent a successful fusion after revision.
  
  
  CONCLUSIONS
  Arthrodesis of the first MTP joint with two 90/90 plates and restoration of length using an interpositional graft has excellent patient satisfaction and functional outcomes.
