Abstract

The angle of inclination of the humerus is the angle between the long axis of the shaft and the central axis of the head of the humerus in the frontal plane. It is about 130° to 150°. Orthopedic surgeons performing reconstruction of the shoulder during prosthetic replacement should consider the size and placement of the head of the humerus. Prosthetic systems with a wide range of modular head sizes, eccentric tapers, and adjustable inclination angles and versions help orthopedic surgeons better to adapt prosthesis to a patient’s bone anatomy. The present study aimed to establish the morphometry of the angle of inclination of the humerus in the Bangladeshi population and to correlate with the previous studies. The present prospective study was carried out with 100 (43 right-sided + 57 left-sided) dried humeri of unknown sex and age. In the present study, the mean±SD angle of inclination of the right humeri was 128.89±3.987 degree and the left humeri were 129.19±3.335 degree. In this article, we review the effects of this anatomical parameter on prosthetic design.
