title: [Treatment of calcaneal malunion fracture with isolated subtalar arthrodesis].
abstract: OBJECTIVE
  To evaluate the effect of treatment of calcaneal malunion fracture with isolated subtalar arthrodesis.
  
  
  METHODS
  Twenty-one patients with calcaneal malunion fracture, with 21 diseases feet, all males, underwent tenolysis of peroneal tendon, lateral exostectomy, and isolated arthrodesis of subtalar joint and were followed up for 16 months (8-47 months). American Orthopedic Foot and Ankle Society and pain score systems were used to evaluate the changes of symptoms. X-ray films were taken to observe the changes of the bones.
  
  
  RESULTS
  The calcaneal deformity was greatly improved in all the patients and the symptom of pain disappeared or was alleviated. The mean post-operational AOFAS score was 71.3 (44-85) points, higher than that before the operation [36.7 (18-56) points]. The pain mean post-operational score was 2.0 (0-4) points, much lower than that before the operation [8.2 (7-10) points].
  
  
  CONCLUSIONS
  Surgical treatment including tenolysis of peroneal tendon, lateral exostectomy, and isolated arthrodesis of subtalar joint is effective on calcaneal malunion fracture.
