What function does the hip bone serve?
What Does a Hip Do? The hip joint is a complex ball-and-socket joint that supports the weight of the body and is responsible for movement of the upper leg. It consists of two main parts: a ball (femoral head) at the top of the thighbone (femur) that fits into a rounded socket (acetabulum), sometimes referred to as the cup, in the pelvis.

What bone does the hip consist of?
The hip bone is formed by three parts: the ilium, ischium, and pubis. At birth, these three components are separated by hyaline cartilage. They join each other in a Y-shaped portion of cartilage in the acetabulum.
Which bone is your 'funny bone'?
elbow. The “funny bone” got its nickname because of that funny feeling you get after you hit it. But your funny bone isn’t actually a bone at all. Running down the inside part of your elbow is a nerve called the ulnar nerve. The ulnar nerve lets your brain know about feelings in your fourth and fifth fingers.
Why is the hip important?
The hip connects the lower extremities to the trunk of the upper body, and its primary function is to bear the body's weight during both static (eg, standing) and dynamic (eg, walking and running) postures. Bones, cartilage, muscles, ligaments, tendons, and other structures all work together to allow this to occur.
What is the main bone in your hip?
The ilium is the largest part of the hip bone and makes up the superior part of the acetabulum. The ala provides an insertion point for the gluteal muscles laterally and the iliacus muscle medially. Anteriorly, the ilium has an anterior superior iliac spine (ASIS); inferior to this is an anterior inferior iliac spine.
What organs are behind your hips?
First and foremost, the hip is the joint where the acetabulum of the pelvic bone and the head of the femur meet....This area relates to the following:Cecum (a pouch) of the large intestine.Appendix.Ascending colon (one of four major regions of the colon)Right ureter (urine duct)Right ovary and fallopian tubes in women.
What makes the hip bone to pain?
Osteoarthritis and rheumatoid arthritis are among the most common causes of hip pain, especially in older adults. Arthritis leads to inflammation of the hip joint and the breakdown of the cartilage that cushions your hip bones. The pain gradually gets worse.
Which part of the hip is most commonly fractured?
Most hip fractures occur in one of two locations on the long bone that extends from the pelvis to your knee (femur): The femoral neck. This area is situated in the upper portion of your femur, just below the ball part (femoral head) of the ball-and-socket joint.
Does bone on bone in the hip cause pain?
OA occurs when cartilage in the hip joint wears away, leaving less protection for the bones, which may become damaged. Bone-on-bone rubbing can result in pain around the hip joint.
What are the 3 main bones of the hip?
Bones and Joints The hip joint is the junction where the hip joins the leg to the trunk of the body. It is comprised of two bones: the thigh bone or femur and the pelvis which is made up of three bones called ilium, ischium, and pubis.
What is the strongest part of the hip bone?
The ischium is the strongest of the three regions that form the hip bone. It is divisible into three portions: the body, the superior ramus, and the inferior ramus.
What is the anatomy of the hip?
Anatomy of the Hip. Like the shoulder, the hip is a ball-and-socket joint, but is much more stable. The stability in the hip begins with a deep socket—the acetabulum. Additional stability is provided by the surrounding muscles, hip capsule and associated ligaments.
Where does the femoral head fit?
The femoral head (ball) fits into the acetabulum (socket) of the pelvis. The large round head of the femur rotates and glides within the acetabulum. The depth of the acetabulum is further increased by a fibrocartilagenous labrum that attaches to the outer rim of the acetabulum.
How thick is the cartilage on the hip?
Hip Anatomy, Function and Common Problems. Normally, a smooth cushion of shiny white hyaline (or articular) cartilage about 1/4 inch thick covers the femoral head and the acetabulum. The articular cartilage is kept slick by fluid made in the synovial membrane (joint lining).
Which ligaments are associated with the capsule?
The capsule and its associated ligaments: e.g. iliofemoral ligament, pubofemoral ligament
Which bone is the longest?
The femur is the longest bone in the body. The neck of the femur connects the femoral head with the shaft of the femur. The neck ends at the greater and lesser trochanters, which are bony prominences of the femur that various muscles attach to.
What are the bones that make up the hip?
Bony Structures of the Hip. The hip is formed where the thigh bone (femur) meets the three bones that make up the pelvis: the ilium, the pubis (pubic bone) and the ischium. These three bones converge to form the acetabulum, a deep socket on the outer edge of the pelvis.
What is the definition of adduction?
Adduction — move toward the body (lowering the leg toward midline i.e. from the side)
What does the hip do?
What Does a Hip Do? The hip joint is a complex ball-and-socket joint that supports the weight of the body and is responsible for movement of the upper leg. It consists of two main parts: a ball (femoral head) at the top of the thighbone (femur) that fits into a rounded socket (acetabulum), sometimes referred to as the cup, in the pelvis.
What is the function of the hip joint?
The structure of the hip joint enables the large range of motion needed for daily activities like walking, squatting, and climbing stairs. Changes, damages or wear to any of the following parts of the hip may lead to physical limitations: Bone substance.
What are the components of the hip bone?
They completely fuse during puberty to form the complex and compact hip bone. The centre of this union is the acetabulum , a deep, cup-shaped socket on the lateral surface of the bone, that articulates with the femoral head at the hip joint. Anteroinferior to the acetabulum is the large obturator foramen. The right and left hip bones make up the pelvic girdle. The bony pelvis is completed posteriorly by the pelvic spine which is composed of the sacrum and coccyx. The bony pelvis connects the axial skeleton to the lower limbs, serving as a weightbearing structure. It also protects and supports the abdominopelvic viscera, provides attachment for several muscles and ligaments, and forms part of the skeletal framework of the birth canal.
What are the parts of the hip?
This bone is the smallest component of the hip bone. It is divided into three main parts: body, superior ramus, and inferior ramus. The body is located anteromedially and the two rami extend posterollatery from the body: the superior ramus extends superiorly to the acetabulum, while the inferior ramus continues inferiorly to join the ischial ramus. It should be noted that some sources consider the body of the pubis to be the superolateral part of the bone which contributes to the formation of the acetabulum, however this is not in accordance with the Terminologia Anatomica.
What is the hip bone?
The hip bone (os coxae) is an irregularly shaped, bilateral bone of the bony pelvis which is also known as the innominate bone, pelvic bone or coxal bone. In reality, it is a compound structure which consists of three smaller bones: the ilium, ischium and pubis. The ilium is the largest and most superior part of the bone, the ischium is located posteroinferiorly, and the pubis or pubic bone forms the anterior portion of the hip bone.
Where is the obturator canal located?
Located anteroinferior to the acetabulum is the obturator foramen, a large opening delimited by the pubis and ischium. Most of this foramen is covered by a flat connective tissue membrane called obturator membrane. A narrow obturator canal remains superiorly between the membrane and adjacent bone through which the obturator nerve, artery and vein pass through while travelling between the pelvic cavity and the medial compartment of the thigh.
What are the three bony surfaces of the Ilium?
The borders of the ilium bound its three bony surfaces: the gluteal, sacropelvic surfaces and iliac fossa.
What is the medial aspect of the ilium?
On the medial aspect of the ilium, posterior to the iliac fossa is the sacropelvic surface, which is composed of the iliac tuberosity, auricular and pelvic surfaces. The auricular surface is an ear-shaped surface that articulates with the sacrum to form the sacroiliac joint. The iliac tuberosity is the posterior portion of the sacropelvic surface; it is a roughened, elevated area that provides a point of attachment for ligaments of the sacroiliac joint. The narrow pelvic surface is found anteroinferior to the auricular surface and contributes to the lateral wall of the lesser pelvis.
What is the ilium of the hip?
The ilium is a blade-shaped bone and the most superior component of the hip bone. It consists of two main parts: the body and ala (wing). The body is the smaller, inferior part of the bone that contributes to the formation of the acetabulum, while the ala is the superior expanded part and presents four borders and three surfaces.
What is the labrum attached to?
Basal surface- attached to the acetabular bone and ligaments. The transverse ligaments surround the hip and help hold it in place while moving. It is thought that the majority of the labrum is avascular with only the outer third being supplied by the obturator, superior gluteal and inferior gluteal arteries.
What is the labrum?
It lines the acetabular socket and attaches to the bony rim of the acetabulum. It has an irregular shape, being wider and thinner anteriorly and thicker posteriorly. On the anterior aspect, the labrum is triangular in the radial section. On the posterior aspect, the labrum is dimensionally square but with a rounded distal surface.
What is the point of articulation between the head of the femurand the acetabulum?
The hip joint is a ball and socket jointthat is the point of articulation between the head of the femurand the acetabulum of the pelvis.
What is an elective hip surgery?
Elective procedure for patients with hip pain secondary to degenerative conditions. Highly effective procedure that relieves pain and restores function to improve quality of life.
What is negative pressure maintenance?
Negative pressure maintenance (i.e., the "vacuum seal") to enhance hip joint stability
What is the function of the hip joint?
Primary function of the hip joint is to provide dynamic support the weight of the body/trunk while facilitating force and load transmission from the axial skeleton to the lower extremities, allowing mobility[1]
Why is the hip joint so strong?
The hip joint is extremely strong, due to its reinforcement by strong ligamentsand musculature, providing a relatively stable joint. Unlike the weak articular capsule of the shoulder, the hip joint capsule is a substantial contributor to joint stability[2]. The capsule is thicker anterosuperiorly where the predominant stresses of weight bearing occur, and is thinner posteroinferiorly.
How long does it take to heal a femur fracture?
Femur fractures generally require surgical repair followed by several weeks of rehabilitation and physical therapy. Dislocations of the hip could require surgery depending on how severe the dislocation is. Physical therapy is almost always required.
How to tell if a hip fracture is a dislocation?
Hip dislocation occurs when the head of the femur is pulled away from the acetabulum (the socket in which the head of the femur rests). It is very difficult to identify the difference between a hip fracture (a broken head or neck of the femur) and a hip dislocation. Some healthcare providers ascribe fractures or dislocations depending on whether the patient's leg is rotated inwardly or outwardly after an injury. In reality, there is no way to tell the difference between a hip fracture or a hip dislocation other than with an X-ray.
What is the lower trochanter?
Below the lesser trochanter is the gluteal tuberosity, which is where the gluteus maximus is attached. The main shaft of the femur is known as the body of the femur.
What is the largest bone in the human body?
Associated Conditions. Rehabilitation. The femur is the largest bone in the human body. It is commonly known as the thigh bone (femur is Latin for thigh) and reaches from the hip to the knee. A human male adult femur is about 19 inches long and weighs a little more than 10 ounces. The femur is extremely hard and not easy to break.
Why is it so hard to fracture a femur?
It's usually very difficult since the femur is such a strong bone. Fractures are usually caused by a high-impact injury, such as falling from a height or a car accident. A fracture caused by a low-impact hit may indicate weaker bones due to a medical condition, such as osteoporosis. 2
How long is a femur?
The femur of an adult male is about 19 inches long and a bit under an inch in diameter. The proximal end of the femur (the part closest to the heart) is the head of the femur.
What is the proximal end of the femur?
The proximal end of the femur (the part closest to the heart) is the head of the femur. The head of the femur is a ball that makes up part of the hip joint. It allows the leg to move at all angles. Below the head of the femur is the neck and the greater trochanter.
