ABSTRACT
Introduction: Calcaneous is largest of seven tarsal bones of foot and forms prominence of heel. Most of the timesan osteophytic outgrowth (calcaneal spur) has been observed in the plantar and dorsal aspect of the foot.Theaim of this study is to analyse the incidence of calcaneal spur in relation to morphological variations of talararticular facets of calcaneus in the state of Odisha, India.Materials and Methods: The material for the study consisted of 107 dry (56 right and 51 left), adult calcanei ofunknown sex obtained from Department of Anatomy. The calcaneal spurs were studied in detail and classifiedaccording to types of calcaneus.Results: The incidence of type 1 calcanei was predominant (66.36%) with least incidence being type 4(1.86%) inthe present study. Maximum incidence of calcaneal spurs were found in Type I calcanei (17.8%) followed by10.28% in Type 2, 4.7% in Type 3 and 0.9% in type 4.One out of 107 calcanei had presented with spur on thesustentaculum tali (0.9%). The incidence and type of calcaneal spurs were compared with those of previousstudies and etiology of heel pain has been discussed.Conclusion: Calcaneal spurs are related to type of calcanei with the highest frequency in Type 1 and least in Type4. Other factors, which contribute toward increase in incidence of spurs, are increasing age and weight, concurrentorthopedic diseases, and heel pain.
