Abstract:

Objective To study the feasibility and clinical efficacy of homemade device（calcaneal trac⁃ tion and reduction control）in the adjuvant calcaneal fracture therapy for surgical treatment. Methods 40 calcaneal fracture patients（41 feet）were collected from January 2014 to August 2016 in Changzhou first people′s hospital. 20 patients（21 feet）were treated with adjuvant homemade device（experiment group），and other patients were treated with traditional method（control group）. According to the radiographic criterion，the plantar imaging exami⁃ nation was followed up. Meanwhile，the postoperative function was evaluated by Maryland Foot Score system， AOFAS and VAS soccer. Results 39 patients（40 feet） were successfully followed up for five years. They all acquired almost normal calcaneus length，height，width，Bohler angle and Gissane angle one year after surgery. And they also have significantly improved Maryland Foot Score，AOFAS score and VAS score one year after surgery compared with pre ⁃ operation. The difference of calcaneus length，height，width，Bohler angle，Gissane angle， Maryland Foot Score，and AOFAS score were significance different between experimental group and control group after five years surgery（P < 0.05）. No patients had incision healing delay or wound infection after surgery. Conclusion The homemade device（calcaneal traction and reduction control）can restore bone length，height， width and calcaneal axis after calcaneal fracture surgery，which is worth popularizing in the clinical treatment.
