Abstract

PURPOSE
To compare the clinical results between the extensile lateral approach and sinus tarsi approach in the open reduction of the Sanders type II calcaneal fracture.
MATERIALS AND METHODS
From July 2002 to Februry 2007, thirty two patients having thirty three calcaneal fractures of Sanders type II were managed with open reduction and internal fixation using the extensile lateral approach or sinus tarsi approach. The mean age of 19 patients using extensile lateral approach was 43.3 years. The mean age of 13 patients using sinus tarsi approach was 46.3 years. Clinical outcome, radiographic parameters, and postoperative complications were compared between both groups.
RESULTS
There was no difference between two groups associated with patients demographs. The mean AOFAS score and VAS between both groups were not different (p=0.716, p=0.774). The mean Bohler's angle and Gissane's angle between both groups were not different (p=0.343, p=0.357). Two cases of sural nerve injury, one malunion, and one deep infection were occurred in the group of extensile lateral approach. However, patients using sinus tarsi approach had no postoperative complications.
CONCLUSION
The clinical results of sinus tarsi approach may be comparable with those of extensile lateral approach, with the advantages of reduced risk of postoperative complications.
