title: [Pseudarthrosis and non-union of disjunctive talar fractures].
abstract: OBJECTIVE
  Neck fractures of the talus are rare. Necrosis is the complication most often observed. Mal union or non union are rarely reported: 11 cases of such complications have been treated and are presented with results of surgical treatment.
  
  
  METHODS
  Seven non unions and 4 mal unions after separation fracture of the talus, presenting with pain and deformity of the hindfoot were treated. The treatment included removal of the fibrous tissue, heel reaxation, bone grafting, peritalar joints arthrodesis.
  
  
  RESULTS
  Bone healing was observed in 5 of 7 non unions, and the correction of the hindfoot deformity in 9 of the 11 cases.
  
  
  CONCLUSIONS
  Non union or mal union after separation fracture of the neck of the talus are poorly tolerated, the patients walking with the foot in internal rotation, bearing most of the weight on the lateral border of the foot. Such poor course results from: the less mechanical stiffness of the medial part of the talus, the severity and the comminution of the fracture, insufficienct reduction and fixation, too early weight bearing, and is associated with degenerative changes of peritalar joints. Functional and antomical good results can be obtained with bone healing, hindfoot reaxation and peritalar arthrodesis. We emphasize the interest of X Rays in the examination and the adequacy of a good initial treatment.
