Abstract

Although calcaneal fracture is relatively common in ankle injury, open intraarticular calcaneal fracture with dorsal dislocation of the navicular from talus is extremely rare and severe injury. There are few data which are available concerning the injury mechanism and treatment options. The purpose of this report is to describe a case with bilateral open transcalcaneal fracture with talonavicular dislocation and to discuss the prevalence, mechanism of this injury, and treatment options.

  Fig. 1 26-year-old woman sustained an open fractures of the both calcaneus and fracture of the lumbar spine by a fall from a height. Initial (A) right and (B) left lateral radiographs show severe comminuted intra-articular calcaneus fracture with talonavicular dislocation. (C) Lateral radiograph of the lumbar spine shows compression fracture of 2nd, 3rd and 4th lumbar vertebral body.

• 

  Fig. 2 (A) Right and (B) left CT semi-coronal view shows the Sanders type IV with severe comminution. (C) CT axial view of the 2nd lumbar vertebra shows compromising the spinal canal by bursting fracture.

• 

  Fig. 3 After irrigation and debridement, closed reduction and percutaneous K-wires and Steinmann pins fixation were performed due to contaminated open fracture.

• 

  Fig. 4 (A) Open reduction and internal fixation with sub-talar arthrodesis by plate and cannulated screw were performed due to severe comminuted intra-articular fracture. (B) Open reduction and internal fixation were performed by extended lateral approach.

• 

  Fig. 5 Lateral radiographs of both calcaneus show maintenance of the reduction of talonavicular joint and good bony union of calcaneus at 14 weeks after operation.
