Introduction/Purpose:
Primary subtalar fusion for Sander IV calcaneus fractures was considered to be the standard of care till recent past. Presently debate is on whether to manage Sander IV calcaneus fracture cases with primary subtalar fusion or with open reduction and internal fixation. Bilateral Sander IV calcaneus fractures are seen in cases with fall from height. No study has ever been conducted till date to compare the results of primary fusion of a Sander IV calcaneus fracture on one side and open reduction and internal fixation on another side in cases with bilateral Sander IV calcaneus fractures. We present a study comparing the results of primary fusion versus open reduction and internal fixation for bilateral sander IV calcaneus fracture cases.
Methods:
Twelve cases with bilateral closed Sander IV calcaneus fractures where included in the present study. Cases were operated between four to six weeks by a single surgeon after the appearance of wrinkles. All right sided fractures underwent open reduction and internal fixation with proximal tibia grafting. While all left-sided fractures underwent subtalar fusion with the use of ipsilateral anterior iliac crest grafts. Cases were followed up for 24 months.
Results:
Though operative time was more in the fusion group wound problems were equal in both the groups. Four months of average time to union was the same in both the groups and so was time to return to work. At two years, the AOFAS score was slightly better in the fusion group but it was not statistically significant.
Conclusion:
Primary subtalar fusion is with almost similar results as those with open reduction and internal fixation in bilateral Sander IV at 24 months. Long term follow up with more number of cases is required to prove the benefit of one over other.
