The zona orbicularis and proximal hip joint capsule are poorly understood. Recent studies seem to confirm that the proximal to middle part of the articular capsule, including the zona orbicularis, acts biomechanically as a locking ring wrapped around the femoral neck and thus is a key structure for hip stability in distraction.
In vertebrate anatomy, the hip, or coxa [1] (pl.: coxae) in medical terminology, refers to either an anatomical region or a joint on the outer (lateral) side of the pelvis.. The hip region is located lateral and anterior to the gluteal region, inferior to the iliac crest, and lateral to the obturator foramen, with muscle tendons and soft tissues overlying the greater trochanter of the femur.

Sacroiliac joint dysfunction is an outcome of either extra-articular dysfunction or from intraarticular dysfunction. SI joint dysfunction is sometimes referred to as "sacroiliac joint instability" or "sacroiliac joint insufficiency" due to the support the once strong and taut ligaments can no longer sustain.
Posterior dislocations is when the femoral head lies posteriorly after dislocation. [5] It is the most common pattern of dislocation accounting for 90% of hip dislocations, [5] and those with an associated fracture are categorized by the Thompson and Epstein classification system, the Stewart and Milford classification system, and the Pipkin system (when associated with femoral head fractures).
The ischium (/ ˈ ɪ s k i. ə m /; [1] pl.: ischia) is a paired bone forming the lower and back part of the hip bone.. Situated below the ilium and behind the pubis, it is one of three regions whose fusion creates the coxal bone.
The sartorius muscle can move the hip joint and the knee joint, but all of its actions are weak, making it a synergist muscle. [4] At the hip, it can flex, weakly abduct, and laterally rotate the femur. [4] At the knee, it can flex the leg; when the knee is flexed, sartorius medially rotates the leg.
The content of the book is organized chronologically and measures hip hop's rise of influence from old-school to alternative hip hop across the world. [7] Among the featured photographic subjects in the book are Notorious B.I.G., Tu Pac, Jay-Z, Nicki Minaj, Eminem, [8] Nas, Kendrick Lamar, Salt-N-Pepa, and Kanye West.
"open your jaw and move it from side to side" to test for pain free normal temporo-mandibular joint movement. "put your hands behind your head with your elbows as far back as they can go. Now try to touch the small of your back" to test for normal sterno-clavicular, gleno-humeral and acromio-clavicular joint movement.
