Name three important factors that contribute to the stability of the hip joint.?

Answer 1

strong ball and socket joint
extensive ligament support
extensive musculature around joint

Answer 2

1)The large head of the femur is completely covered in hyaline cartilage . This is the site of attachment for an intracapsular ligament (called the ligamentum teres) that attaches directly from the head of the femur to the acetabulum. The head of the femur is attached to the pelvis by neck region

2)Capsule
The strong but loose fibrous capsule of the hip joints permits the hip joint to have the second largest range of movement (second only to the shoulder) and yet support the weight of the body, arms and head.The capsule is attached proximally to the entire periphery of the acetabulum beyond acetabular labrum.The capsule covers the femoral head and neck like a sleeve and attaches to the base of neck. The capsule has two sets of fibers:the longitudinal and circular fibers.The circular fibers forms a collar around the femoral neck called the zona orbicularis.the longitudinal retinacular fibers travel along the neck and carry blood vessel. As the line of gravity falls posterior to the axis of the hip joint, the combined weight of the body seeks to extend the hip joint in normal standing and make the trunk fall backwards to the ground. To resist the stretching action on the anterior joint capsule in normal upright posture, the hip has two very strong anterior ligaments.


3)Ligaments
The hip joint is reinforced by three main ligaments.

At the front of the joint, the strong iliofemoral ligament attaches from the pelvis to femur. This Y-shaped ligament is also known as the ligament of Bigelow. This ligament seeks to resist excessive extension of the hip joint. It is often considered to be the strongest ligament in the human body.
The pubofemoral ligament attaches across the front of the joint from the pubis bone of the pelvis to the femur. This ligament is orientated more inferiorly than the iliofemoral ligament and reinforces the inferior part of the hip joint capsule. It also blends with the medial parts of the iliofemoral ligament.
The posterior of the hip joint capsule is reinforced by the ischiofemoral ligament that attaches from the ischial part of the acetabular rim to the femur.
There is also a small ligament called ligamentum teres or the ligament of the head of the femur. The ligament is a triangularly shaped band with its base on both sides of peripheral edge of acetabular notch .

Answer 3

The tendons, ligaments, and muscles that cross the joint. An intact nervous system that innervates the joint. The acetabular labrum.

Answer 4

A hip joint needs a low cover charge, no 3 drink minimum, and not having last call a half hour before closing.

Answer 5

1. not being hit by a bus
2. not falling out of a tree
3. not being stepped on by an elephant
