What is inserted to the quadrate tubercle?
What is inserted to the quadrate tubercle?
The quadrate tubercle is the site of insertion of the quadratus femoris muscle.
Where is the quadratus tubercle?
the femur
The quadrate tubercle is a small tubercle found upon the upper part of the femur, that serves as a point of insertion of the quadratus femoris along with the intertrochanteric crest and the linea quadrata.
What is the intertrochanteric crest?
Anatomical terms of bone The intertrochanteric crest is a bony ridge located on the posterior side of the head of the femur, stretching obliquely downward and medially from the summit of the greater trochanter to the lesser trochanter.
What attaches to the intertrochanteric line?
The joint capsule of the hip and the iliofemoral ligament insert on the intertrochanteric line. Furthermore, the vastus medialis muscle originates from the inferior portion of the intertrochanteric line.
What is the purpose of intertrochanteric line?
Just like the intertrochanteric crest on the posterior side of the femoral head, the intertrochanteric line marks the transition between the femoral neck and shaft. The distal capsular attachment on the femur follows the shape of the irregular rim between the head and the neck.
How do you fix an intertrochanteric fracture?
Intertrochanteric fractures are treated surgically with either a sliding compression hip screw and side plate or an intramedullary nail. The compression hip screw is fixed to the outer side of the bone with bone screws. A large secondary screw (lag screw) is placed through the plate into the femoral head and neck.
What is an intertrochanteric fracture?
Introduction. Intertrochanteric fractures are defined as extracapsular fractures of the proximal femur that occur between the greater and lesser trochanter. The intertrochanteric aspect of the femur is located between the greater and lesser trochanters and is composed of dense trabecular bone.
What is the quadrate tubercle?
The quadrate tubercle is a small tubercle found upon the upper part of the femur, that serves as a point of insertion of the quadratus femoris along with the intertrochanteric crest and the linea quadrata . The quadrate tubercle is located about the junction of the upper one-third and lower two-thirds, on the intertrochanteric crest.
Where is the quadrate tubercle on the intertrochanteric crest?
The quadrate tubercle is located about the junction of the upper one-third and lower two-thirds, on the intertrochanteric crest. The size of the tubercle varies; it is not always located on the intertrochanteric crest.
What is the prevalence of displaced greater tuberosity fractures?
Isolated displaced greater tuberosity fractures are thought to occur in less than 2% of proximal humeral fractures, and are normally associated with anterior shoulder dislocations.
What are the treatment options for tuberosity fractures?
Fixation of smaller fractures can be accomplished with heavy sutures, wire or occasionally, screws. Rotator cuff tears associated with the fracture are also closed. If in the case of a large greater tuberosity fracture, a deltopectoral approach would allow for more adequate exposure for reduction and proper fixation.
