Analysis of effect of new procedure on intra-articular fracture of calcaneus

Objective To investigate the effect of surgical operation on intra-articular fracture of calcaneus by new method.Methods Between August 2004 and February 2007,183 feet in150 patients with calcaneal fracture were treated differently based on the results of X-ray and coronal CT scan performed before and after the treatment.The small incision(2-3 cm) was made at lateral of calcaneus by micro-invasive technique,and self-made calcaneal anatomical plate and screw were used.Based on the results of X-ray and coronal CT scan and according to Sanders classification system,there were 62 cases of type Ⅱ,87 cases of type Ⅲ and 34 cases of type Ⅳ.Results The internal fixation with the calcaneal anatomical plate almost restored the height,length,width,angle of Bhler's and Gissane's of the calcaneus for the 150 patients.None of infection of incision occurred.The results were validated by using Maryland Foot Score.183 cases of fractures were followed up for 6～36 months(mean 18.3 months) after treatment.Excellent results were noted in 86(47.54%)cases of fractures,good in 81 cases(43.72%),and fair in 16 cases(8.74%).Conclusion The open reduction with micro-invasive and internal fixation with self-made calcaneal anatomical plate and screw is one of the best ways in the treatment of fracture of calcaneus.
