hip joint anatomy

The hip is a synovial joint of the ball-and-socket variety formed by the globular femoral head cupped into the acetabular or cotyloid cavity of the hip bone. The hip joint is this joint here between the head of the femur and the acetabulum of the pelvis.This joint is a ball-and-socket synovial joint and it’s a very stable joint unlike the shoulder joint, which is very mobile, but not so stable.

This […], Musculoskeletal tumors are a rare and diverse group of tumors. There is a difference between symptoms of instability and patellar dislocation, though the former may cause the latter to happen. It functions as flexor, abductor and external rotator of the hip joint. Acetabulum . The ball and socket articulation allows for a high degree of mobility. These ligaments have a unique spiral orientation and this causes them to become tighter when the joint is extended adding stability to the joint. artificial hip joint metal hip hip joint 3d pelvis bone hip joint bone hip replacement hip joints anatomy hip orthopedic hip replacements hip anatomy.

The normal hip is often described as a synovial ball and socket joint but this hardly does it justice. The acetabulum is formed from parts of the ilium, ischium, and pubis. The iliacus arises from the ilium and the psoas major arises from the lumbar vertebrae. Basilar invagination is an abnormality where the skull floor is indented by the upper cervical spine. 2 Citations; 332 Downloads; Abstract. The muscle gradually narrows into a flattened tendon and is inserted into the base of the patella. It also contains a branch of the obturator artery that forms a small portion of hip joint blood supply. The labrum functions to lubricate the articular cartilage and stabilize the joint (Seldes 2001, Stafford 2009). It takes origin along the anterior region of the sacrum, extends laterally, passing through the greater sciatic foramen and crossing the hip joint to insert on the greater trochanter of the femur. Primary function of the hip joint is to provide dynamic support the weight of the body/trunk while facilitating force and The hip is a ball-and-socket joint, similar to the joint in the shoulder.

Flexion of the knee which relaxes the hamstrings, and increases the range of flexion to full. It attaches to the anterior inferior iliac spine and the acetabular rim proximally. The fibers converge and pass posterolateral and upward, to form a tendon that runs across the back of the neck of the and is inserted into the trochanteric fossa of the femur. Hip Anatomy. The acetabulum is formed by the merging of the ossification centers of ilium, ischium and pubis bones of pelvis. Acetabular labrum is a fibrocartilaginous rim like structure that functions to deepen the acetabulum to enable better holding of the femoral head. The hip joint, or acetabulum, is responsible for many movements including walking, bending and crouching. Its proximal end takes part in the formation of the hip joint. The fixed joint capsule forms an envelope around the hip joint. The hip joint is a ball-and-socket synovial joint which connects axial skeleton [pelvis] to lower limb [femur]. It is also referred to as a ball and socket joint and is surrounded by muscles, ligaments, and tendons. The hip joint is innervated by the femoral nerve, obturator nerve, superior gluteal nerve, and nerve to quadratus femoris. The iliacus and psoas major muscles are closely related in structure and function and are often referred to as a single muscle, the iliopsoas. Arun Pal Singh is an orthopedic and trauma surgeon, founder and chief editor of this website. The movements  and their range at the hip joint are. The hip joint is a ball-and-socket joint formed between the pelvis and the femur (thigh bone). The cavity of the acetabulum faces obliquely forward, outward, and downward. Some deeper fibers go around the neck, forming the orbicular zone, which holds the femoral neck in the acetabulum.

The lesser trochanter is a bony prominence on the proximal medial aspect of the femoral shaft, just distal to the femoral neck. Hip Anatomy The hip joint is the largest weight-bearing joint in the human body. It originates on the ischial part of the acetabular rim and spirals superolaterally to the neck of the femur, medial to the greater trochanter. They also medially rotate the lower leg when the knee is bent. The intracapsular ligaments are located in the hip joint cavity. Obturator nerve [L2-L4] supplies the skin over upper inferomedial thigh. At puberty, the 3 primary bones are still separated by a Y-shaped triradiate cartilage centered in the acetabulum. The rectus femoris constitutes quadriceps muscle along with vastus lateralis, vastus medialis, and vastus intermedius.

Hip Anatomy - The Acetabular Joint. Between them is a Y-shaped cartilaginous growth plate (the triradiate cartilage) which is usually fused by age 14-16. Adductor magnus , longus, brevis and minimus are adductor muscles of hip and originate as, They all insert on medial ridge of linea aspera [A thickened ridge on posterior femur]. It consists of the acetabulum (hip socket) and the femoral head (ball) of the femur. The hip joint is a ball-and-socket joint; the round head of the femur rests in a cavity (the acetabulum) that allows free rotation of the limb. It forms a connection from the lower limb to the pelvic girdle, and thus is designed for stability and weight-bearing – rather than a large range of movement. It is also referred to as a ball and socket joint and is surrounded by muscles, ligaments, and tendons. The hip is the body’s second largest weight-bearing joint (after the knee). The iliofemoral ligament or Y ligament of Bigelow is the anterior ligament. The ligaments of the hip joint act to increase stability. It is the strongest ligament. A problem with any one of these parts of the hip anatomy can result in pain. The fibers are directed obliquely downward and lateralward. Hip joint can also get dislocated. An adult body contains about one kilogram of calcium. This website is an effort to educate and support people and medical personnel on orthopedic issues and musculoskeletal health. The permitted movements at the hip joint are the following: flexion and extension, abduction and adduction, external or lateral rotation and internal or medial rotation of the thigh. Because the joint surfaces are neither maximally congruent nor close packed, the hip joint is at greatest risk for traumatic dislocation when flexed and adducted (30,31). It is the fifth most abundant element in the human body. Limb formation begins by the fourth week of the embryonic life.

Sartorius, the longest muscle in the human body is a long, thin, band-like muscle that arises from the anterior superior iliac spine, descends obliquely across the hip joint and thigh and then runs medially and inferiorly to insert on the medial side of the tibia in the lower leg. The hip region is located lateral and anterior to the gluteal region, inferior to the iliac crest, and overlying the greater trochanter of the femur, or "thigh bone". The quadratus femoris is a flat, quadrilateral skeletal muscle located on the posterior side of the hip joint and is a strong external rotator and adductor of the thigh. Piriformis  is one of six short external rotators [others being superior gemellus, inferior gemellus, obturator internus, obturator externus, and quadratus femoris muscles – together known as depp gluteals] and participates on the abduction of hip also. Ligament of head of femur is a small ligament that runs from the acetabular fossa to the fovea of the head of the femur. The hip is a complicated mechanism and therefore hip pain can originate in many different parts of the joint. How Does a Hip Joint Move?

The two unite and spread into an aponeurosis which is prolonged downward on the anterior surface of the muscle, and from this, the muscular fibers arise. Hip joint replacement is a common surgery performed to replace the diseased or injured hip. It is a flat, quadrangular muscle that arises from the pectin pubis or the pectineal line and from the surface of the bone just in front of it. Stability and movement thanks to ligaments and muscles It is the bony structure which makes this joint so very stable: The femoral head rests relatively securely in the amply sized concave acetabulum.
