Abstract
The management of fractures of os calcis remains highly controversial. The fractures involving subtalar joint may cause serious and persistent disabilities. Recently, the computed tomography (CT) scan has been shown to he superior in evaluating the intraarticular fractures of calcaneus and the most widely used classification is based on the number of fragments especially seen on. Although the classification of calcaneal fractures hy CT, tongue type and joint depression type fractures hy plain radiographic views have been commonly used. Generally, closed reduction and axial fixation with metallic pin for tongue type fractures and open reduction and internal fixation for joint depression type fractures have been performed. The authors did so. The 13 fractures were tongue types and 17 fractures were joint depression types. The intraarticular calcaneal fractures of 30 feet in 26 patients who were treated at Our Lady of Mercy Hospital were analyzed in clinical and radiological aspects from Mar.1991 to Apr.1996. The results were as follows:
1. Of 30 cases, 16 fractures were treated with closed reduction and pinning, and 14 fractures were treated with open reduction and internal fixation.
2. The preoperative, postoperative and the last follow-up average Bohlers angle were 6.0, 21.0 and 20.5 respectively.
3. The preoperative, postoperative and the last follow-up average Gissanes angle was 106, 129 and 126 respectively.
4. Based on assessment of the criteria of Salama et al 19), excellent results were 5, good results were 14, fair results were 6 and poor results were 5.
5. All the five cases of poor results were tongue type fractures and they were treated with closed reduction and axial pinning.
6. Of 7 fractures using autogenous iliac bone graft, 6 fractures were good, I fracture was fair and there was no poor results. Therefore, open reduction and internal fixation for joint depression type calcaneal fractures was thought to be a good method of treatment. But we must consider whether axial fixation with metallic pin for tongue type calcaneal fractures will be a good method of treatment.
