Introduction: Calcaneum is a cancellous bone that tend to unite with collapse after fracture. Controversy is ongoing regarding the use of bone grafts to fill cavities that occur with collapse of the posterior facet in the joint and for repair of the calcaneal height with plating.
Aim of The Study: The aim is “To compare the results of displaced intra -articular calcaneal fractures treated with and without bone graft substitute Hydroxyapatite”.
Materials And Methods: The study included 20 patients of intra articular calcaneal fractures admitted in RMMCH from June 2015 to September 2017. All the patients are treated with open reduction and internal fixation with locking calcaneal plate. By random allocation in 10 patients artificial bone graft substitute Hydroxyapatite is used and in 10 patients bone graft substitute was not used. The calcaneal height and Bohler's angle were compared between the 2 groups. The final functional outcome was evaluated by Modified Maryland Foot Score, with excellent defined as 90 - 100 points, good as 75 - 89 points, fair as 50 - 74 points and poor as <50 points.
Results: In patients treated with bone graft Excellent Modified Maryland Foot Score was achieved in 6 patients, Good in 2, Fair in 1 and poor in 1 patient. In patients treated without bone graft Excellent modified Maryland Foot score was achieved in 7 patients, good in 1, fair in 1 and poor in 1 patient.
Conclusion: There is no significant difference in the functional outcome between patients treated with bone graft substitute and patients treated without bone graft substitute.
