title: [Osteosynthesis of talonavicular fusion with a claw plate and compression screw].
abstract: OBJECTIVE
  A new method of osteosynthetic stabilization of talonavicular fusion is presented.
  
  
  METHODS
  Idiopathic and posttraumatic talonavicular arthritis, talonavicular destruction in rheumatoid arthritis, adult acquired flatfoot deformity, cavovarus deformity, talonavicular degenerative disease in tarsal coalition.
  
  
  METHODS
  Major hindfoot deformity or instability, severe osteopenic conditions of tarsal bones.
  
  
  METHODS
  Talonavicular fusion is stabilized with a medioplantar 6.5-mm lag screw in combination with a dorsolateral 3.5-mm claw plate (Charlotte Claw compression plate; Fa. Wright Medical Technology, Memphis, USA) by a dorsal surgical access.
  
  
  METHODS
  Nonweight-bearing in a cast or walker for 6 weeks; after radiologic control increasing weight-bearing is allowed.
  
  
  RESULTS
  The technique was used in 44 patients, among them 31 cases of isolated talonavicular fusion. Complete bony healing was observed in 42 cases after medium follow-up time of 13.3 months. All 19 cases of isolated talonavicular fusion without posterior tibial tendon dysfunction healed uneventfully; two cases of non-union were observed in 12 patients with posterior tibial tendon dysfunction.
