TO COMPARE THE BONY PARAMETERS OF HIP AND SHOULDER JOINTS FOR UNDERSTANDING THEIR ROLE IN DISLOCATION
Objective: The purpose of this study is to compare the bone of shoulder with that of hip joint for any structural changepertaining
to variation in stability of these joints due to trauma or pathological processes.
Material and Methods: This study work was carried out on bones collected from cadavers in Anatomy department
of KGMC Peshawar from January 2012 to December 2014. A total number of 11 pairs of humeri, 12pairs femurs, 10
pairs of scapulae and 14 pairs of hip bones were included in this study. The measurement of different part of bone were
performed with help of vernier caliper and recorded on observation sheet. For measurement of weight the electronic
scale, equipped with a high precision sensor system, was used.
Results: The mean diameter of right glenoid cavity was less as compared to left glenoid cavity but the depth of right
glenoid cavity was more than that of left glenoid cavity. Both diameter and depth of right acetabulum were less as
compared to left acetabulum.The mean diameter of humeral head and thickness of articular surface were less on right
sidewhich were not significant. The diameter of right humeral neck was significantly less as compared to left side.
The mean diameter of right femoral head and neck were more as compared to left side but the thickness of femoral
head was less on right side which was not significant. All bony parameters were significantly different in shoulder joint
as compared to hip joint.
Conclusion: A significant asymmetry exists in parameters of shoulder and hip joint which can be a factor affecting
their mobility and stability. The difference noted in right and left sides were not significant.All these findings may have
implication for regional prosthetic design and implantations.
