B. Bursae Trochanteric bursa Ischial Bursa Gluteofemoral bursa (aka – intermuscular
The Gluteofemoral bursa is found here under the muscle
F. Clinical Concerns Piriformis SyndromeHow to get rid of a pain
in the buttocks.It is thought to be
caused by an impingement of the sciatic nerve by the shortening or tightening of the piriformis muscle.
G. Surface Anatomy Gluteal fold (aka -
Gluteal sulcus) Intergluteal cleft
G. Surface Anatomy
Supracristal Plane (SCR)This is best described as a transverse plane
passing through the tops or summits of the iliac crests; it usually passes through the fourth lumbar spinous process.

The Hip (Iliofemoral) Joint is a diarthrosis, or synovial triaxial articulation permitting movement in all three planes. Structural Classification: Ball-and-socket
Acetabular Labrum: projecting rim located on the fibrocartilaginous layer which increases depth of joint cavity
Articular Cartilage of Head of Femur: opposing cartilage surface (shown in blue)
Articular CapsuleDense collagen fiber sleeve which surrounds the joint providing protection and stabilization. Covers approximately the proximal two thirds of the neck of the femur posteriorly. Synovial Membrane: lines the joint cavity and produces synovial fluid. Fibrous Layer: attaches proximally on the hip bone to the rim of the acetebelum and the transverse acetabular ligament
The Hip Joint is composed of the articulation between the Os Coxae and the Femur. The Os Coxae is made up of three bones: the Ilium, the Ishium and the Pubis. (The Os Coxae also articulates with the Sacrum at the Sacroiliac Joint) The Acetabulum is a concave socket shared by all three bones on the lateral surface which articulates with the Head of the Femur.
Movements of the Hip Joint
Four Iliac Spines can be found on the margins of the Ilieum. These spines are attachment points for muscles and ligamentsand include the Anterior-Superior and Inferior spines and the Posterior-Superior and Inferior spines. The very superior point of the Ileum is called the Iliac Crest. Inferior to the Iliac Crest on the medial portion is a shallow depression called the Iliac Fossa, or Wing. Just inferior to the Posterior-Inferior Iliac Spine lies the Greater Sciatic Notch.
The Ischium forms the posterior, inferior portion of the Os Coxae. The Ischial Spine projects superior to the Lesser Sciatic Notch. The Ischial Tuberosity lies at the posterior and lateral edge of the Ischium. The Ischial Ramus connects the Ischium to the Pubis. The Inferior Ramus of the Pubis meets the Ischium and extends to the Pubic Crest. Just superior to the crest the Superior Ramus connects the Pubis to the Ilieum. Together, the Ischium and the Pubis encircle the Obturator Foramen.
The Symphysis Pubis, a pad of fibrocartilage, interconnectsthe medial anterior surfaces of both hip bones together.
The Pubic Arch is formed by the inferior rami of the Pubis and Ishium of the two sides.
A male pelvis has a pubic angle of 90 degrees or less. A female pelvis has a pubic angle of 100 degrees or more.
Femur: The longest and heaviest bone in the bodyThe rounded Head of the Femur articulates with the acetabulum of the pelvis to form the Hip Joint. The Femur runs from the Hip Joint to articulate with the Tibia to form the Knee Joint. The Neck of the Femur joins the shaft at 125 degrees.The Greater Trochanter projects laterally. The Lesser Trochanter projects posteriorly and medially. These trochanters are where large tendons attach to the Femur.
The Linea Aspera is a prominent elevation which runs along the posterior surface and serves as an attachment site for hip muscles.
The Pectineal Line is located just beneath the Lesser Trochanter.
The Adductor Tubercle is a bony prominance which can be found just above the medial epicondyle.
TibiaThe Tibia articulates with the Femur at the Medial and Lateral Tibial Condyles. The condyles are separated by a ridge called the Intercondylar Eminence. The Tibial Tuberosity lies near the condyles and is large and rough enough to be felt through the skin.The Anterior Margin or Crest of the Tibia runs from the Tibial Tuberosity down the anterior surface.
