ASSESSMENT OF BOHLER'S AND GISSANE’S ANGLES OF THE CALCANEUM IN A GROUP OF SOUTH INDIAN POPULATION - A RADIOLOGICAL STUDY
Author: Rahe Ramachandran, Shailaja Shetty
Calcaneus is the largest tarsal bone designed to withstand the daily stresses of weight bearing. Bohler’s and Gissane’s angles are subtended by the Calcaneus, these angles are used in the assessment of Calcaneal fractures.
Objective: Measuring the Bohler’s and Gissane’s angles from computed ankle radiographs and comparing the results with previous studies.
Materials and Methods: This study was done in M.S. Ramaiah teaching hospital and M.S. Ramaiah memorial hospitals, Bangalore, India. Study was conducted on 92 patients older than 17 years. The angles were measured and the variation in range was compared with that of the previous studies.
Observation and Results: From this study it was observed that the Bohler’s angle ranges between 18.7 – 46.2 degrees. Gissane’s angle ranges between 87.5 – 137.8 degrees. The normal international reference values are; Bohler’s angle 280 to 400 and Gissane’s angle 1200 to 1400. The lower limit of Bohler’s angle in our study group, like few other studies is found to be much less than the reference values which is used to diagnose Calcaneal fractures.
Conclusion: The range of Bohler’s and Gissane’s angles in the Indian population is much less when compared to the standard reference values, indicating that range of the angles is variable in different population groups. Hence knowledge of the exact range of the angles in a specific population group aids in accurate diagnosis and meticulous treatment of Calcaneal fractures.
