Osteology Of Pelvis

📌𝐅𝐨𝐥𝐥𝐨𝐰 𝐨𝐧 𝐈𝐧𝐬𝐭𝐚𝐠𝐫𝐚𝐦 :-   / drgbhanuprakash   The pelvis consists of the sacrum, the coccyx, the ischium, the ilium, and the pubis. The structure of the pelvis supports the contents of the abdomen while also helping to transfer the weight from the spine to the lower limbs. During gait, the joints within the pelvis work together to decrease the amount of force transferred from the ground and lower extremities to the spine and upper extremities. Bony Pelvis ------------------- Until puberty, each hip bone consists of three separate bones yet to be fused: ilium, ischium and pubis connected by the tri-radiate cartilage. The two hip bones are joined anteriorly at the pubic symphysis and posteriorly to the sacrum at the sacroiliac joint. The hip bones incorporate the acetabulum, which articulates with the proximal femur at the hip joint. In addition to carrying upper body weight, this multi-surfaced pelvic ring can transfer upper body weight to the lower limbs and act as attachment points for lower limb and trunk muscles. Furthermore, the bony pelvis protects the pelvic and abdomino-pelvic viscera Joint Articulations ------------------------------ Ligaments of the pelvis The pelvic bones make 4 pelvic joints. One sacrococcygeal joint posteriorly, a hinge joint between the sacrum and the coccyx. 2 sacroiliac joints with the sacrum, the strongest joints in the body. 1 symphysis pubis anteriorly, a cartilaginous joint with cartilage in between. Other articulation: The pelvis and femur articulate via the acetabulum, at the hip joint. #osteologyofpelvis #pelvisosteology #anatomy #osteology #usmle #usmlestep1 #usmlevideos #nationalexittest #mbbslectures #usmlestep2ck #usmlestep1videos #usmlepreparation
