What is the significance of linea aspera in the femur?
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 lateral and medial intermuscular septa that divides the thigh into three compartments.
In which bone is the linea aspera found?
the femur
The linea aspera is a longitudinally-oriented ridge on the posterior aspect of the femur to which several muscles of the thigh attach. It is comprised of medial and lateral lips which diverge at both its superior and inferior ends.
What is the most common femur fracture?
The most common types of femoral shaft fractures include: Transverse fracture – The break is a straight horizontal line going across the femoral shaft. Oblique fracture – The fracture has an angled line across the shaft. Spiral fracture – The fracture line encircles the shaft like the stripes on a candy cane.
What are the articular surfaces of femur?
The articular surface of the lower end of the femur occupies the anterior, inferior, and posterior surfaces of the condyles.
What does linea aspera mean?
The linea aspera is a longitudinally-oriented ridge on the posterior aspect of the femur to which several muscles of the thigh attach. It is comprised of medial and lateral lips which diverge at both its superior and inferior ends.
Which of the following muscles attaches at the linea aspera?
Adductor magnus
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—viz., the Glutæus maximus inserted above, and the short head of the Biceps femoris arising below.
Where is the linea aspera of the femur located?
posterior
What attaches to the linea aspera femur?
The adductor part attaches distally to the linea aspera, the gluteal tuberosity on the femur and the medial supracondylar line on the distal femur. The hamstring portion attaches onto the femur at the adductor tubercle on the inferomedial portion of the bone.
How long does it take for a broken femur to stop hurting?
At some point, you may need physical therapy to restore strength and flexibility to your muscles. Doing your exercises as prescribed can improve your chances for a full recovery. Most femoral fractures take about 4 to 6 months to heal completely, but you should be able to resume many activities before this time.
Where is the linea aspera of the femur?
The linea aspera is the rough, longitudinal, irregular crest on the posterior surface of the shaft of the femur. It is formed by the joining of lateral and medial lips, which may be separated by up to 10 mm [1]. It is divided distally into medial and lateral supracondylar ridges.
What are the most distal surfaces of the femur?
The distal end of the femur is made up of the medial and lateral condyles, the intercondylar fossa, and the patellar surface.
