Oct 30, 2023 · Bones, ligaments, movements, blood supply and innervation of the hip joint. The hip joint is a ball and socket type of synovial joint that connects the pelvic girdle to the lower limb. In this joint, the head of the femur articulates with the acetabulum of the pelvic (hip) bone.

Jan 21, 2022 · The hip joint is a ball and socket synovial joint, formed by an articulation between the pelvic acetabulum and the head of the femur. 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.

The hip joint is a ball and socket joint that is the point of articulation between the head of the femur and the acetabulum of the pelvis. Hip Joint 1. Diarthrodial joint with its inherent stability dictated primarily by its osseous components/articulations. 2. Primary function of the hip joint is to provide dynamic support the weight of the body/t...
The hip joint connects the lower extremities with the axial skeleton. The hip joint allows for movement in three major axes, all of which are perpendicular to one another. 1. The location of the center of the entire axis is at the femoral head. 2. The transverse axis permits flexion and extension movement. 3. The longitudinal axis, or vertically al...
In general, the hip joint capsule is tight in extension and more relaxed in flexion. The capsular ligaments include 1. Iliofemoral ligament (also known as the Y ligament of Bigelow) is the strongest ligament in the body; it lies on the anterior aspect of the hip joint - it prevents hyperextension, 2. Pubofemoral lies anteroinferiorly - it prevents ...
The labrum forms a fibrocartilagenous extension of the bony acetabulum, mostly composed of type 1 collagen that is typically between 2-3mm thick. 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 t...
Numerous variations in the blood supply to the hip. 1. Most common variant results in blood supply coming from the medial circumflex and lateral circumflex femoral arteries, each of which is a branch of the profunda femoris (deep artery of the thigh). 2. The profunda femoris is a branch of the femoral artery which travels posteriorly. 3. There is a...
Muscles of the hip joint can be grouped based upon their functions relative to the movements of the hip Flexors: 1. Psoas Major 2. Psoas Minor 3. Iliacus 4. Pectineus 5. Rectus Femoris Extensors: 1. Gluteus Maximus 2. Semitendinosus 3. Semimembranosus 4. Biceps Femoris (long head) Adductors: 1. Adductor Magnus 2. Adductor Longus 3. Adductor Brevis ...
Full extension of the hip joint is the closed packed postionbecause this position draws the strong ligaments of the joint tight, resulting in stability.
The hip joint is one of the only joints where the position of optimal articular contact (combined flexion, abduction, and external rotation) is the open-packed, rather than closed packed position, since flexion and external rotation tend to uncoil the ligamentsand make them slack.
Total hip arthroplasty(THA) 1. 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. 2. Indicated for patients who have failed other conservative methods, including corticosteroid injections, physical therapy, weight reducti...
May 30, 2024 · Anatomy of the hip joint. The hip is a ball-and-socket joint where the rounded head of the femur fits snugly into the acetabulum of the pelvis. This structure allows multiple movements, including flexion, extension, abduction, adduction, and internal and external rotation.

Jan 30, 2023 · Your hip joint is a connection point between your legs and your torso. Specifically, it’s made up of your thigh bone (femur) and your hip bone (pelvis). It’s a ball-and-socket joint that supports your body weight and allows you to move your upper leg.
The main functions include carrying small vessels and nerves to the femoral head and providing proprioception and structural stability to the hip joint by limiting abduction and external rotation when the hip is flexed.
