abstract
This study was conducted to elucidate the gross morphological and osteometrical features of the femur of rhesus monkey. The shaft was cylindrical and curved cranially. The caudal surface was concave and presented a rough area, facies aspera, which extended from the level of lesser trochanter to the nutrient foramen. The foramen index (FI) of left femur bone was 67.14 indicating its position at distal 3^rd of the caudal surface of the shaft. Nutrient foramen was not seen on any of the surfaces of shaft of right femur bone. Supra-condyloid fossa was shallow. The medial supra-condyloid crest was more prominent than the lateral one. The left femur (21.00 cm) was longer than the right (19.00 cm) one. The proximal extremity was comprised of head, neck, greater trochanter, lesser trochanter, trochanteric ridge and deep trochanter fossa. Head was circular in outline with distinct deep fovea capitis which was elongated oval. The greater trochanter was undivided and above the level of the head. Lesser trochanter was in the form of a tuberosity. Trochanteric ridge was well developed. Trochanter fossa was deep and extensive. The distal extremity consisted of trochlea in front and condyles behind. Trochlea consisted of two unequal ridges, lateral and medial. Lateral ridge was more pronounced than the medial ridge. Caudally, medial and lateral condyles were separated by deep inter-condyloid fossa. Medial condyle was larger than the lateral one.
