Intertrochanteric line, pectineal line of femur, linea aspera, medial supracondylar line of femur: Insertion: Tibial tuberosity (via patellar ligament), patella, (medial condyle of tibia) Action: Knee joint: Leg extension: Innervation: Femoral nerve (L2-L4) Blood supply: Femoral, deep femoral, descending genicular artery It is helpful in a modified transfemoral approach or in the posterior approach of the femur. Figure 1 shows the linea aspera of the FEMUR Bone. head of fibula and lateral condyle of tibia. This is a raised longitudinal impression that runs along the long axis of the femur. Based on the osteometric measurements that were done, there are 4 types of LA that have been identified [5]: Variform LA is considered to be the most common type found in humans accounting for around 40%. [1] It is the site of attachments of muscles and the intermuscular septum. It is made up of a medial and a lateral lip; the former originating near the lesser trochanter, and the latter arising from the greater trochanter. Superiorly, lateral lip blends with broad and rough gluteal tuberosity, and the medial lip continues as narrow spiral line. Linea aspera was widest at its lower one third 30 (62.5%) and narrowest at its middle one-third 5 (10.4%). Aside from this, the LA may function as a resistance pole which can stiffen the femur within its forward prominence [3, 5]. linea al´ba white line; the tendinous median line on the anterior abdominal wall between the two rectus muscles. Adductor longus originates from the pubis and expands into a fan shape, inserting onto the linea aspera of the femur. In a cemented total hip arthroplasty, the LA is an important area for the protection against fat embolism [3, 5]. Knowing all the possible variations of the LA will be beneficial in detecting possible tumor growth such as a calcinosis-like growth that may be located in the LA. 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. Actions include hip adduction and medial rotation of the thigh. RESULTS: The linea aspera was externally rotated in most femora evaluated; average angles of rotation were 15.4°, 14°, 11.7°, and 11.5° at 10, 15, 20, and 25 cm from the intercondylar line, respectively. [2, 3, 4]. The tension generated by muscle attached to the bones is responsible for the formation of the ridges. Absent in youth, the LA emerges during early puberty and becomes more prominent with advancing age. Medial lip is at left; lateral lip is at right. The anterior compartment includes pectineus, iliopsoas, psoas minor, iliacus, sartorius and the quadriceps muscles. The adductor magnus is inserted into the LA and between this muscle and the vastus lateralis is where the gluteus maximus and the short head of the biceps femoris originate [4, 5]. linea al´ba white line; the tendinous median line on the anterior abdominal wall between the two rectus muscles.

The Linea aspera located on the posterior margin of the femur diaphysis is considered a tomographic, imaging and anthropological reference. The symptoms dramatically resolved after the patient underwent neurolysis of the tract of the nerve adjoining to the linea aspera. Imaging studies of the thigh showed a delimited zone of hyperostosis in the proximal third of the femoral diaphysis. The linea aspera (LA) forms a characteristic ridge along the posterior aspect of the human femur. Biceps femoris: origin: ischial tuberosity and linea aspera of femur A number of muscles attach to the linea aspera: The linea aspera is perforated a little below its center by the nutrient canal, which is directed obliquely upward.[1]. B. The linea aspera (LA) forms a characteristic ridge along the posterior aspect of the human femur. The linea aspera of the femur is a pronounced longitudinal elevation referred to as a ridge or crest present in the midsection of the bone. Its margins diverge above and below. Like every other bone in the body, it has marks and features that makes them an ability to connect to other bones. The adductor magnus is inserted into the linea aspera, and to its lateral prolongation above, and its medial prolongation below. When translated from Latin, LA means “rough line.” LA is the roughened, longitudinal irregular crest that is composed of 2 lips. On anteroposterior projections of the femur in adults and rarely, in adolescents, the linea aspera may appear as The mean diameter of antero posterior thickness was 2.7±1.1 mm. Below, the linea aspera is prolonged into two ridges, enclosing between them a triangular area, the popliteal surface, upon which the popliteal artery rests. The main function of the LA is the support and stabilization of the femur during walking and running as it serves as the attachment site of several muscles. By most measures the two femurs are the strongest bones of the body, and in humans, the longest. 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. The linea aspera (LA) is the distinctive ridge found along the posterior aspect of the femur. This feature is the insertion site of the adductor thigh muscle. origin: ischial tuberosity and linea aspera of femur insertion: action: flexes leg at knee, extends and laterally rotates thigh.
