title: [Case-control study on conservative and operative therapy in the treatment of intra-articular fracture of calcaneus].
abstract: OBJECTIVE
  To explore the traumatic mechanism and the effectiveness of conservative and operative therapy for intra-articular fracture of calcaneus.
  
  
  METHODS
  Forty-eight patients (52 feet) with intra-articular fractures were divided into two groups named as conservative group and operative group. There were 30 patients in the conservative group, including 26 males and 4 females, ranging in age from 2 to 73 years, with an average of (49.2 +/- 8.5) years. The patients in conservative group were treated with manual reduction, external fixation and functional exercise at early time. Among 18 patients in the operative group, 14 patients were male and 4 patients were female, ranging in age from 26 to 66 years,with an average of (50.1 +/- 19.3) years. The patients in the operative group were treated with open reduction and internal fixation. The height and width of calcaneus, Böhler and Gissane angles were measured before and after treatment. The assessment in the function of ankle joints was scored according to AOFAS scoring system.
  
  
  RESULTS
  All the patients were followed up, and the duration ranged from 8 to 18 months,with a mean of 12 months. The time of weight-bearing ranged from 3 to 6 months, averaged 4 months. The fractures were fused completely on average of 12 months. The height and width of calcaneus, Böhler and Gissane angles had no statistically significance between two groups. According to AOFAS criteria,in the conservative group, 18 patients reached an excellent result, 6 good, 5 poor and 1 bad; in operative group, 4 patients reached an excellent result, 7 good, 6 poor and 1 bad. The therapeutic effect of conservative group was better than that of operative group.
  
  
  CONCLUSIONS
  Operative therapy in intra-articular fracture of calcaneus with steel plate can directly perceive the restoration (or roughly restoration sometimes) of the anatomical shapes of calcaneus, while conservative therapy has advantages such as restoration of the anatomical shapes of calcaneus, early functional practice, early healing, and avoiding operational complications as well.
