What is a linea aspera in anatomy?
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.
Is linea aspera a bone?
Anatomical Parts 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.
What is the lateral lip of linea aspera?
lat·er·al lip of lin·e·a as·pe·ra. [TA] the lateral margin of the linea aspera of the femur that gives attachment to the lateral intermuscular septum and the short head of the biceps femoris muscles.
What is spiral line of femur?
a curved line with its superior end adjacent to the lesser trochanter, nearly continuous with the intertrochanteric line, and converging inferiorly with the pectineal line to form the medial lip of the linea aspera; forms the medial boundary of the distal attachment of the iliacus muscle.
What muscles attach at linea aspera?
Attachments
- lateral and medial intermuscular septa.
- adductor muscles. pectineus. adductor minimus. adductor brevis. adductor longus. adductor magnus (hamstrings part)
- biceps femoris (short head)
- vastus lateralis and medialis.
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.
Why is the linea aspera important?
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.
Why is it called the linea aspera?
History and etymology In Latin, linea means “line” and aspera means “rough” 7.
Where is the linea aspera of 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 stabilizes the hip joint?
The iliofemoral, pubofemoral and ischiofemoral ligaments are very strong, and along with the thickened joint capsule, provide a large degree of stability. These ligaments have a unique spiral orientation; this causes them to become tighter when the joint is extended.
Which long bone of man has linea aspera?
the femur
Muscles of the Medial Aspect of the Thigh The attachment to the shaft of the femur is long, and in man is marked by the linea aspera (roughened line) on the posterior surface of the bone.
What are the first signs of hip problems?
The following signs are frequent early symptoms of a hip problem:
- Hip Pain or Groin Pain. This pain is usually located between the hip and the knee.
- Stiffness. A common symptom of stiffness in the hip is difficulty putting on your shoes or socks.
- Limping.
