Hip Joint and Pelvic Girdle

by Fatin Nadhiratul Husna



1)      Hip joint is a plane joint.
2)      Female pelvis has heart shaped inlet.
3)      Male has conical lesser pelvis while female has cylindrical lesser pelvis.
4)      Greater sciatic foramen of female is 90˚.
5)      Sacroiliac Joints is between the sacrum and the coccyx.
6)      Pubic symphysis is between the pubis bodies of the two hip bones.
7)      Transfer of weight from the upper axial sketeton to the lower appendicular components of the skeleton, especially during movement is the function of the pelvis.
8)      The only intracapsular ligament is the ligament of the head of femur.
9)      There are two intracapsular ligament that are iliofemoral and pubofemoral ligaments.
10)   Iliofemoral ligament originates from the ilium, immediately inferior to the anterior inferior iliac spine.
11)   Iliofemoral ligament prevent hyperextension of the hip joint.
12)   The primary pelvic girdle joints are sacro-iliac joint and pubic symphysis.
13)   Pubofemoral ligament prevents over abduction of hip.
14)   Ischiofemoral  is a strong ligament.
15)   The lateral circumflex femoral artery is responsible for the majority of the arterial supply.
16)   Damage to the medial circumflex femoral artery can result in avascular necrosis of the femoral head.
17)   The lateral circumflex femoral artery has to penetrate through the thick iliofemoral ligament to reach the hip joint.
18)   The hip joint is innervated by the femoral nerve, obturator nerve, superior gluteal nerve only.
19)   Gluteus maximus, semimembranous,semitendinosus and biceps femoris help in extension.
20)   Gluteus medius and minimus, semitendinosus and semimembranosus help in lateral rotation.
21)   Adductors longus, brevis and magnus,pectineus and gracillis help in adduction.
22)   The movements that can be carried out at the hip joint are flexion, extension, abduction, adduction and medial/lateral rotation.
23)   At the hip joint quadriceps femoris is the principle flexor.
24)   Profunda femoris artery contributes little to  the cruciate anastomosis.
25)   Blood supply to the head of the femur may be impaired if the joint capsule is torn.
