Introduction: Clavicle has a complex bone structure, is variable in shape and exhibits dramatic variations both in curvatures and cross sectional geometry. Clavicle has been globally studied for purpose of generating a suitable, correct and economical treatment of clavicular fractures.
Objective: The present study was done to determine the total diameter of bone, combined cortical thickness and cortical index i.e (proportion cortical thickness to total diameter) of adult clavicles.
Material method: 200 pairs (200 males and 200 females) of adult clavicles of known sex obtained from bony collections and cadaveric dissections were cut parasagittally and measurements were taken at midclavicle level. The clavicular parameters (cortical index, total diameter of clavicle and combined cortical thickness) measured for known sex were compared. The data obtained was analyzed statistically.
Results: The values obtained for all parameters were found to be higher in case of males as compared to females. When parameters as measured for the right and left sides were compared for same sex there was not much difference. Values for right and left sides were very much close to each other.
Conclusion: The present study establishes the morphometeric criterion for cortical index, total diameter of clavicle and combined cortical thickness in north Indians and compared the observations with therefore other populations and races giving a special emphasis on the influence of sex factor on these parameters.
