Fracture of the calcaneus is the most commonly encountered among fracture of tarsal bone and it is difficult to obtain accurate reduction because the calcaneus has cancellous trabecular enclosed with thin cortical bone. In the past, the result of treatment was poor. Recently, closed reduction and axial pin fixation for tongue type fracture and open reduction and internal fixation for joint depression type fractures are considered as generally accepted treatment methods. The purpose of this study is to evaluate the efficacy of axial pin fixation in joint depression(group A) and tongue type(group B). Retrospective study was performed in 20 patient(23 feet) with intraarticular calcaneal fractures which were treated with axial pin fixation from July 1993 to June 1996. Minimum follow up period was 1 year(average 20 months). The obtaining results were as follows : 1. Cause of injury was fall down in the 18 cases(90%). 2. We obtained excellent or good results from the performance of operation within 2 weeks on trauma patient, in the 16 cases(69%). And we obtained excellent or good results in the 14 cases, showing above 20degreesof postoperative B.. ohler angle. 3. In fracture of joint depression type, there is no relationship between clinical result and degree of joint depression in follow up CT. 4. The complications were subtalar arthritis and two neuroma in sural nerve. We propose our experience obtained in 23 cases that axial pin fixation was a good method for treatment of intraarticular fracture, joint depression type as well as tongue type.
