Abstract

Introduction: Talus fractures are commonly occur secondary to high energy mechanisms, management of the talus fracture in the multiply injured patient can be difficult. An important principle remains emergent reduction of dislocated joints whenever possible. Stabilization of the fractures and dislocations facilitates management of the soft tissues. However a good result for the talus fracture can still be seen, even when appropriate orthopaedic intervention is delayed due to multisystem injury.

Aim: To study about the functional outcome of talus fracture following internal fixation by using cannulated cancellous screws.

Materials & Methods: Prospective evaluation of 17 patients in the age group of 15 years to 75 years with good general condition underwent open reduction and internal fixation with canulaed cancellous screw fixation for simple and compound fracture of talar body and talar neck upto compound grade II during August2014 to September 2016. The periodic evaluations were done clinically and radiologically at regular intervals. Post operatively patients were assessed using AORAS scoring system.

Results: Among the 17 patients 29.41 percent of patients had excellent Hawkin’s functional outcome, 35.29 percent of patients had good outcome and 35.29 percent had fair outcome while none had poor outcome. The mean post op AOFAS score is 58.58 and mean follow up AOFAS score is 91.41.

Conclusion: In our study treatment of fracture talus with open reduction and screw fixation facilitated early mobilisation of the patients and helped achieving stable, pain free subtalar and ankle joints and preventing avascular necrosis of talus, subtalar and ankle joint arthritis. AOFAS score has significant improvement during follow up.
