Besides the first perforator, the medial and lateral circumflex femoral arteries and the inferior gluteal artery participate in the cruciate anastomosis. Vascular anatomy. The head is attached to the femoral body or shaft by the neck of the femur. The adductor group has a varied role during gait. The neck’s posterior surface has a concave appearance. 4.5.1 General; 4.5.2 Gross; … Lateral – Medial border of the sartorius muscle. The ball-and-socket configuration provides stability while allowing a wide range of joint motion. Drawing of the ligaments as they are attached to the hip. With kicking, the rectus femoris contracts strongly. The ball and socket articulation allows for a high degree of mobility. From here, it passes midway between the anterior spine of the ilium and symphysis pubis and continues down the medial and front side of the thigh. Drawing of the major muscle groups of the hip. The gluteus maximus, along with the adductor magnus, is also responsible for climbing and rising from a sitting position. The upper third of the artery is contained in the femoral triangle, which is also know… In the sciatic notch, the sciatic nerve is vulnerable to injury from pelvis fractures and, distal to the notch, vulnerable to injury from posterior dislocation of the femoral head. Identify the following regions in the image above: Rectus abdominus - Greater omentum - Urinary bladder dome - Ileum - Femoral artery & vein - Iliopsoas - Sartorius - Tensor fascia latae - Gluteus medius - Gluteus maximus - Femoral head - Fovea of femoral head - Round ligament - Ischium - Uterus - Rectouterine pouch - Coccyx - Rectum - Pelvic diaphragm - Obturator internus The other branches of the obturator nerve innervate the anterior portion of the knee joint, which helps explain why patients with hip disorders may have anterior knee pain in the absence of significant pain about the hip. References 1. In addition to these primary centers of ossification, the adolescent has seven other centers of secondary ossification, which include the iliac crest, ischial apophysis, anterior inferior iliac spine, pubic tubercle, angle of pubis, ischial spine, and the lateral wing of the sacrum. The head of the femur (thighbone) forms the ball, and the acetabulum forms the socket. They are cushioned by these muscles and are not likely to be injured by hip dislocation or pelvic fractures. 1. The pelvis is formed from the fusion of three separate centers of ossification: the pubis, ischium, and ilium. Although the role of an impaired blood supply of the femoral head in the pathogenesis of osteonecrosis has not been clarified, several studies have found abnormal blood supply in patients with osteonecrosis. The strongest flexor is the doublebellied iliopsoas muscle. The femur of an adult male is about 19 inches long … Despite this, there is great mobility between the femoral head and the acetabulum. These terminal branches form two retinacu-lar vascular systems, posterior-superior and posterior-inferior. The zona orbicularis, the name given to the deep circular fibers of the iliofemoral ligament, may be mistaken arthroscopically for the acetabular labrum. Each hip was disarticulated, and standardized measurements were taken. Femoral head separation (FHS) is a degenerative skeletal problem in fast-growing poultry wherein the growth plate of the proximal femur separates from its articular cartilage. lateral vessels provide the greatest volume of the femoral head; LFCA gives rise to the anterior vessels & the MFCA gives rise to the rest; Subsynovial Ring (of Chung) Forms from the retinacular vessels as ring on the surface of neck at margin of the articular cartilage; Epiphyseal arteries enter the head from here These muscles contract to accelerate the leg forward. It is convenient to think of the muscles in functional groups when describing muscular control; however, an individual muscle may contribute to more than one functional movement. (Cerezal)".
