The calcaneus is the most frequently fractured tarsal bone. Although there were many reports of treatment using variable methods, but no definite general agreement to the treatment method of the intra-articular calcaneus fracture. From May. 1995 to Apr. 1997, 14 displaced intra-articular fractures of the calcaneus in 12 patients underwent open reduction and heterogenous bone graft (Lubboc, TRANSPHYTO S.A., France) at the Dept. of Orthopaedic Surgery, Dankook University Hospital The fractures were 13 joint depression type and 1 tongue type fractures according to the classification of Essex-Lopresti. The average follow-up was 20 months and clinical assessment underwent by Clinical Assessment Rating system of Hutchinson and Huebner; we got a satisfactory results for the treatment of displaced intra-articular calcaneus fracture by open reduction and heterogenous bone graft. We didn't need harvesting autograft by use of heterogenous bone graft into bone defect site instead of autograft. Our purpose of using heterogenous bone were filling of defect and internal fixation. We used minimal skin incision and minimal internal fixation device, so reduced complications such as wound edge necrosis and peroneal entrapment caused by entensile appraoch. There were no posterior facet depression and decreased B hler angle for 1 year follow up.
