RADIOGRAPHIC EVALUATION OF ELBOW JOINTS IN ADULTS IN CENTRAL INDIAN POPULATION
Dr. Sachin Upadhyay and Dr. Tarun Singh*
Background: The carrying angle is defined as the acute angle made by the median axis of the arm with the fully extended and supinated forearm. It is important in walking, swinging and carrying objects. Various studies have been done on the cause of the formation of carrying angle. Variations in carrying angle have been reported with age groups, gender and race but little attention has been given to correlate the carrying angle with various anthropological parameters. Hence this study was done to co-relate the carrying angle with various anthropological parameters. Materials and Methods: The present study was a prospective cross sectional study done between 1stJanuary 2017 to 1st January 2019in the Department of Orthopaedics, NSCB Medical College & Hospital, Jabalpur (M.P.). A total of 354 consenting healthy volunteers were screened for the study who were the relatives and attenders of the patients admitted in the orthopedics ward. A total of 300 healthy volunteers who qualified the inclusion criteria were included in the study all of whom were right hand dominant. Results: The mean carrying angle on the dominant side in our study for males is 10.19 degrees with standard deviation of 1.175degrees and for females is 13.44 degrees with standard deviation of 0.610 degrees and on the non dominant side in our study for males is 9.72 degrees with standard deviation of 1.063degrees and for females is 13.38 degrees with standard deviation of 0.634 degrees. The anterior humeral capitellar line on the dominant side intersects the capitellum in its anterior third in 16.7%, intersects the middle third in 55.3% and the posterior third in 28%. The mean articular surface angle is 82.8 degrees with standard deviation of 4.501 degrees. The mean transepicondylar distance on non dominant side to be 6.21cm ranging from 5.1 to 6.9 cm and on the dominant side to be 6.19cm ranging from 5.2 to 7.3 cm with average of both elbows being 6.2cm ranging from 5.1 cm to 7.3cm. Conclusion: We concluded that the carrying angle showed variations in sex, side as well as with increasing age. So it needs to be normalized according to all this criterias and a single value for everyone is not an acceptable cut off to diagnose injuries around the elbow. We came to the conclusion that 2 parameters -carrying angle and trans-epicondylar distance if measured routinely and regularly both pre-op and post-op can be used to reduce the early post operative complications like stiff elbow and restricted range of motion.
Keywords: Carrying angle, transepicondylar line.
