Classic measuring techniques4 were used for observation of features of linea aspera, including the use of Vernier caliper.
Table-2: Width of linea aspera in relation to its levels.
In our study we measured the maximum anterio-posterior diameter of linea aspera which###Micheal J pitt in his study described pilaster as cross sectional elevation of ridge on
We have observed that linea aspera can have upto three ridges###M Polguj in his study described that linea aspera has two ridges9
The principal nutrient foramina of the femur are located toward the middle of the linea aspera (Schaeffer, 1953; Orts-Llorca, 1963; Testut & Latarjet, 1971) with a possible variation in number and position, located in proximity to the linea aspera, generally one is located near the proximal extremity of the linea aspera and a second, that is not always present, in proximity to its distal extreme (Williams & Warwick, 1995), can be found in a point of the medial surface of the bone always near the linea aspera (Rouviere & Delmas, 1999).
The nutrient foramina of the femur was located in the linea aspera in the 72,5% (36.25% in the interstice 8,75 in the lateral lip and 27,5 in the medial lip of the linea aspera, in the 21,25% in the medial face and in the 6,25% in the lateral face of the diaphysis of the bone.
(1994) who pointed out that in the femur the nutrient foramina is restricted to a linea aspera or adjacent zones, locating itself in the medium third of the bone.
