The linea aspera (Latin: rough line) is a ridge of roughened surface on the posterior surface of the femur, to which are attached muscles and intermuscular septum.

Its margins diverge above and below.

The linea aspera is a prominent longitudinal ridge or crest, on the middle third of the bone, presenting a medial and a lateral lip, and a narrow rough, intermediate line. It is an important insertion point for the adductors and the intermuscular septa that divides the thigh into three compartments. The tension generated by muscle attached to the bones is responsible for the formation of the ridges.

Structure

Above

Above, the linea aspera is prolonged by three ridges.

The lateral ridge is very rough, and runs almost vertically upward to the base of the greater trochanter. It is termed the gluteal tuberosity, and gives attachment to part of the Glutæus maximus: its upper part is often elongated into a roughened crest, on which a more or less well-marked, rounded tubercle, the third trochanter, is occasionally developed.
The intermediate ridge or pectineal line is continued to the base of the lesser trochanter and gives attachment to the Pectineus;
the medial ridge is lost in the intertrochanteric line; between the intermediate and medial ridges a portion of the Iliacus is inserted.

Below

Below, the linea aspera is prolonged into two ridges, enclosing between them a triangular area, the popliteal surface, upon which the popliteal artery rests.

Of these two ridges, the lateral is the more prominent, and descends to the summit of the lateral condyle.
The medial is less marked, especially at its upper part, where it is crossed by the femoral artery. It ends below at the summit of the medial condyle, in a small tubercle, the adductor tubercle, which affords insertion to the tendon of the Adductor magnus.

Development

The tension generated by muscle attached to the bones is responsible for the formation of the ridges.

Function

A number of muscles attach to the linea aspera:

From the medial lip of the linea aspera and its prolongations above and below, the Vastus medialis originates.
From the lateral lip and its upward prolongation, the Vastus lateralis takes origin.
The Adductor magnus is inserted into the linea aspera, and to its lateral prolongation above, and its medial prolongation below.
Between the Vastus lateralis and the Adductor magnus two muscles are attached:
- the Gluteus maximus inserted above,
- and the short head of the Biceps femoris originating below.
Between the Adductor magnus and the Vastus medialis four muscles are inserted:
- the Iliacus and Pectineus above;
- the Adductor brevis and Adductor longus below.

The linea aspera is perforated a little below its center by the nutrient canal, which is directed obliquely upward.

Effects of ligation of lateral intermuscular septum perforating vessels on blood supply to the femur.

Grob K1, Manestar M2, Lang A3, Ackland T4, Gilbey H5, Kuster MS6.
Injury.Injury.2015 Dec;46(12):2461-7. doi: 10.1016/j.injury.2015.09.029. Epub 2015 Oct 22.
INTRODUCTION: With a subvastus approach to the femur, the vessels that perforate the lateral intermuscular septum (LISP-vessels) must be ligated. The effect on the blood supply to the femur remains unclear. The purpose of the current study was to investigate the effect of ligation of the LISP-Vessel

The geometry of the femur is important in the final position of an intramedullary implant; we hypothesised that the femoral geometry changes with age and this may predispose the elderly to anterior mal-positioning of these implants. We used CT DICOM data of 919 intact left femora and specialist soft

Rotational malalignment during femoral nailing is common despite having various intraoperative assessment methods. The cortical step sign and diameter difference sign (CSSDDS) is commonly used because of convenience, yet it lack proper scientific scrutiny and is thought to be error prone. Using a so
