Intertrochanteric line
Encyclopedia
The intertrochanteric line (or spiral line of the femur ) is a line located on the anterior side of the proximal end of the femur
.
The rough, variable ridge stretches between the lesser trochanter
and the greater trochanter
forming the base of the neck of the femur, roughly following the direction of the shaft of the femur. The iliofemoral ligament
— the largest ligament of the human body — attaches above the line which also strengthen the capsule of the hip joint
.
The lower half, less prominent than the upper half, gives origin to the upper part of the Vastus medialis
.
Just like the intertrochanteric crest
on the posterior side of the femural head, the intertrochanteric line mark the transition between the femural neck and shaft.
The distal capsular attachment on the femur follows the shape of the irregular rim between the head and the neck. As a consequence, the capsule of the hip joint
attaches in the region of the intertrochanteric line on the anterior side, but a finger away from the intertrochanteric crest on the posterior side of the head.
The fibers of the ischiocapsular ligament attaches both on the joint capsule and to the intertrochanteric line.
intertrochantric fractures;
this area of the femur being the important pillar for weight bearing of the body is subject to lot of dynamic stress, pathological strain, physiological strain and trauma. this area gets injured and fractured due to high velocity trauma in young and treveal trauma in the old. the fractures in this line are called intertrochantric fractures and are classified as per the pattern of the fracture geometry. this bone unites as this is a spongy bone but is nutoriously known for its union in unacceptable positions. it need surgical fixation invariably for early mobilization and return to independent life style.
Femur
The femur , or thigh bone, is the most proximal bone of the leg in tetrapod vertebrates capable of walking or jumping, such as most land mammals, birds, many reptiles such as lizards, and amphibians such as frogs. In vertebrates with four legs such as dogs and horses, the femur is found only in...

The rough, variable ridge stretches between the lesser trochanter
Lesser trochanter
The lesser trochanter of the femur is a conical eminence, which varies in size in different subjects-Anatomy:It projects from the lower and back part of the base of the femur neck.From its apex three well-marked borders extend:...
and the greater trochanter
Greater trochanter
The greater trochanter of the femur is a large, irregular, quadrilateral eminence and a part of the skeletal system.It is directed a little lateralward and backward, and, in the adult, is about 1 cm lower than the head...

Iliofemoral ligament
The iliofemoral ligament is a ligament of the hip joint which extends from the ilium to the femur in front of the joint. It is also referred to as the Y-ligament or the ligament of Bigelow, and any combinations of these names....

Capsule of hip joint
The articular capsule is strong and dense.Above, it is attached to the margin of the acetabulum 5 to 6 mm. beyond the labrum behind; but in front, it is attached to the outer margin of the labrum, and, opposite to the notch where the margin of the cavity is deficient, it is connected to the...

Vastus medialis
The vastus medialis , often called the 'teardrop' muscle, is a medially located muscle of the quadriceps.-Function:The vasti appear to act largely in a co-ordinated manner throughout the control of knee extension...

Intertrochanteric crest
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....
