Lumbar and hips

The acetabulum is a key structure in the hip, featuring a notch bridged by the transverse acetabular ligament, which supports the round ligament of the femur. This area is vital for blood supply to the femoral head.

Acetabulum

The acetabulum has a notch that is bridge by the transverse acetabulum ligament

The round ligament of the head of the femur arises from the transverse acetabular ligament and inserts onto the fovea capitis of femur. This structure carries blood vessels and head of the femur.

Composed of ilium, ischial, and pubic

Lumbar and hips

Menisci

Reduces localized pressure on the articular surfaces by improving congruency
Increases concavity of the tibial condyle (Joint Stability)
Provides proprioception via tension on coronary ligaments and muscular attachments
Semimembranosus attaches to medial meniscus and Popliteus attaches to lateral meniscus
Gets Nutrition vis osmosis

Physical Therapy Applications

Trendelenburg Sign
If the right gluteal muscle is weak = left side will drop when the patient stands on right leg
Produced when a patient is asked to stand on one leg and the opposite side that is not standing on the ground drops (pelvic drop). Superior glute nerve innervates the gluteus medius and minimus which plays an important role in stabilizing the pelvis during locomotion.
Trochanteric Bursitis
This occurs when there is an inflammation of the bursitis. Results from repetitive actions such as climbing stairs or even running on a treadmill. These movements involve the gluteus maximus which moves superior tendinous fibers repeatedly back and forth over the bursa of the greater trochanter.

Bursae

Ischial Bursa: Located between the Gluteus maximus and the Ischial tuberosity
Gluteofemoral bursa: Located between the Gluteus maximus and then greater trochanter
Trochanter Bursa: Located between the greater trochanter and the gluteus maximus
Obturator Externus Bursa: Located between the Obturator externus muscle and the posterior neck of the femur
Obturator Internus Bursa: Located between the obturator internus muscle and then ischial spine and tuberosity

Blood Supply

Femoral Artery then goes down the adductor canal and exits through the adductor hiatus and turns into popliteal artery
In the femoral triangle, the profunda femoris artery arises and travels posteriorly giving off : perforating branches, lateral femoral circumflex, medial circumflex.
Under the inguinal ligament the femoral nerve then enters the femoral triangle
The internal iliac artery becomes anterior and posterior iliac artery and they innervate the pelvic girdle
External iliac artery turns into femoral artery & internal iliac artery turns into anterior and posterior iliac artery (below the inguinal ligament)
External and internal iliac artery (at L4 and L5)
Common iliac artery
