title: A retrospective comparison of first metatarsophalangeal joint arthrodesis using a locked plate and compression screw technique.
abstract: BACKGROUND
  The historic primary treatment for end-stage first metatarsophalangeal (MTP) joint arthritis has been fusion. Traditionally, this has been accomplished by metaphyseal apposition between the proximal phalanx and metatarsal using crossed compression screws. Recently, locked plates have been introduced that help support this technique by offering added stability. We present our experience with 45 first MTP fusions in 45 feet using a locked plate and compression screw.
  
  
  METHODS
  A retrospective review of 45 patients who met the study criteria with a hallux rigidus correction using a locked plate with a compression screw was performed. Charts and radiographs were independently reviewed by 2 authors not involved in the index procedures to assess outcomes.
  
  
  RESULTS
  There was a 93% fusion rate (42/45 feet) with 3 nonunions. The mean time to union was 51.1 days (range = 29-116 days, SD = 24.4). The mean patient age was 58.1 years (range = 29-80 years, SD = 10.1). The mean time to partial weight bearing was 7.0 days (range = 0-53 days, SD = 13.8) and the mean time to full weight bearing was 62.0 days (range = 29-57 days, SD = 17.9).
  
  
  CONCLUSIONS
  We report on the results of first MTP fusion using a compression screw and locked plate technique. The results show that this is an effective means of creating a first MTP joint arthrodesis.
