What is the trochanteric fossa of femur?

What is the trochanteric fossa of femur?

The trochanteric fossa, a deep depression at the base of the femoral neck is indicated as ‘piriform fossa’ in the vast majority of the publications. Other publications indicate the insertion site of the tendon of the piriformis muscle on the greater trochanteric tip as ‘piriform fossa’.

What muscles are inserted into the trochanteric fossa of femur?

The trochanteric fossa serves as the point of insertion for four muscles:

• Obturator externus.
• Obturator internus.
• Superior gemellus.
• Inferior gemellus.

What attaches in the trochanteric fossa?

Description. The medial surface of the greater trochanter presents at its base a deep depression, the trochanteric fossa (digital fossa), for the insertion of the tendon of the Obturator externus, and above and in front of this an impression for the insertion of the Obsturator internus and Gemelli.

Where is the trochanteric fossa?

The deep depression posteriorly between the trochanter and head is the trochanteric fossa. On the posterior surface of the shaft, just distal to the head, is the lesser trochanter. The intertrochanteric line connects the two trochanters, but is especially defined along the posterior edge of the greater trochanter.

What inserts in piriformis fossa?

Piriformis fossa is anatomical site of insertion of obturator externus.

What is Calcar femoris?

The calcar femorale is a spur of thickened bone that lies deep to the lesser trochanter but posterior to the neutral axis of the femoral neck. The calcar is thickest medially where it joins the compression buttress of the neck and gradually thins as it passes laterally.

What causes greater trochanter pain?

Causes. GTPS can be caused by: Overuse or stress on the hip from exercising or standing for long periods. Hip injury, such as from a fall.

What is acetabular fossa?

The acetabular fossa is a fossa located at the centre of the acetabulum. It is occupied by the ligament of head of femur. Acetabular fossa. Lateral view of the right hip bone.

What nerve goes through piriformis?

The majority of piriformis muscles are innervated by the superior gluteal nerve.

What is Ward’s triangle?

Ward’s triangle is a space formed near the center of femoral neck by the intersection of three trabecular bundles, namely, the principal compressive, the secondary compressive, and the tensile trabecular.

What is the function of calcar femorale?

The calcar femorale can bear compression load and redistributes stress or load from the femoral head to the proximal femur. The calcar femorale also contributes to the strength of the femoral neck. Bigelow described the calcar femorale as ‘the true neck of the femur’.

Is walking good for greater trochanteric pain syndrome?

Symptoms of greater trochanteric pain syndrome Pain is worse with lying directly on your hip, walking up and downstairs, and prolonged walking and running.

How do you sleep with Greater Trochanteric Pain Syndrome?

Avoid lying on the painful side or with the painful leg crossed over the other as in the picture below. Try lying on your back with a pillow under your knees, or lie on your good side with pillows between your legs to keep them parallel as shown below.

What passes through acetabular foramen?

nutrient vessels
The notch is converted into a foramen by the transverse acetabular ligament; through the foramen nutrient vessels and nerves enter the joint; the margins of the notch serve for the attachment of the ligament of the head of the femur….
