Observational Study of Gerdy's Tubercle on Fully Ossified Dry Human Left Tibia

Abstract

Introduction: Gerdy's tubercle is a lateral tubercle of the upper end of tibia where the iliotibial tract inserts. The aim of this study is to find out the shape of Gerdy's tubercle on fully ossified dry human left tibia with their clinical association. Materials and methods: The present study is an observational analytic type of study which was performed on of two hundred (200) fully ossified dry human left tibia of unknown sex, conducted in the department of Anatomy, Sir Salimullah Medical College, from July 2014 to June 2015.In this study fully ossified dry human left tibia of unknown sex were collected from the department of Anatomy and also from the students of Sir Salimullah Medical College (SSMC), Dhaka, Ibrahim Medical College (IMC), Dhaka, Dhaka National Medical College (DNMC), Dhaka and Bangladesh Medical College (BMC), Dhaka. Results: The shape is evaluated subjectively and tubercles classified as type A was found in 55.0%, type B in 13.5 %, type C in 15.5%, type D in 4 %, type E in 9 % and type F in 3%. In male Type A was found in 58.2%, Type B in 15.3%, Type C in 12.2%, Type D in 4.1%, Type E in 8.2% and Type F in 2%. In female Type A was found in 52%, Type B in 11.8%, Type C in 8.6%, Type D in 3.9%, Type E in 9.8% and Type F in 3.9%. Conclusion: The different shapes of Gerdy’s tubercle demonstrated in the present study may contribute to produce significant effect on surgical interventions and some shapes may be more prone to traumatic injuries on it.
