Hip Lab Brandee Johnson Cindy Dong Ken Bufford Hip joint is a --------------------- joint? Ball-and-socket Name the joint which connects sacrum with the iliac crest? Sacroiliac joint Articulation of which bone makes the hip joint? The head of the femur and acetabulum of the pelvis What are three parts of the pelvic bone? Ilium Ischium Pubis Name the ligaments of hip joint? Iliofemoral ligament Pubofemoral ligament Ischiofemoral ligament Teres ligament Name the different movements possible in hip joint and the Axis and Plane of each movement. Movement Axis Plane Flexion Frontal Sagittal Extension Frontal Sagittal Abduction Sagittal Frontal Adduction Sagittal Frontal External/Internal Rotation Vertical Transverse Diagonal Abduction Sagittal Frontal Diagonal Adduction Sagittal Frontal Anterior/Posterior Rotation Frontal Sagittal Lateral Rotation Sagittal Frontal Transverse Rotation Vertical Transverse What is the normal range of the movement taking place in hip joint? Flexion – 120° Extension – 30° or less Abduction – 45° Adduction – 20° Rotation – 90° To kick a ball for a longer distance you need which muscle to be stronger? Iliopsoas (extend hip) Quadriceps (extend knee) Gracilis (groin muscle) Label the following in the figure. a-Greater trochanter b-illium c- ischium d-pubis e- ASIS f-lesser trochanter g- sacroiliac joint h-iliac crest i-inferior pubic ramus j- Femoral neck k- sacroiliac joint l- coccyx Iliac crest Sacroiliac joint Ilium ASIS Greater trochanter Coccyx Pubis Femoral neck Inferior pubic ramus Lesser trochanter Ischium Muscle Origin Insertion Action Innervations Adductor magnus Edge of the entire pubis ramus and the ischium and ishial tuberosity Whole length of the linea aspera, inner condyloid ridge and adductor tubercle Adduction of the hip External rotation as the hip adducts Extension of the hip Anterior: Obturator Nerve (L2-L4) Rectus femoris Anterior inferior iliac spine and notch below the spine of the ilium and groove (posterior) above the acetabulum Superior aspects of the patella tendon to the tibia tuberosity Flexion of the hip Extension of the knee Anterior: Pelvic rotation Femoral Nerve (L2-L4)) Sartorius Anterior superior iliac spine and notch below the spine Anterior medial surface of the tibia just below condyle Flexion of the hip Anterior pelvic rotation External rotation of the thigh as it flexes the hip and knee Abduction of the hip Femoral Nerve (L2, L3) Posterior: Sciatic Nerve (L4, L5, S1-S3) Muscle Origin Insertion Action Innervations Gracilis Anteromedial edge of the descending ramus of the pubis Anterior medial surface of the tibia below the condyle Adduction of the hip Weak flexion of the knee Assists w/ flexion of hip Internal rotation of the hip Obturator Nerve (L2-L4) Pectineus Space 1 in wide on the front of the pubis just above crest Rough line leading from lesser trochanter down to linea aspera Flexion of the hip Adduction of the hip External rotation of the hip Femoral Nerve (L2-L4) Name the primary hip flexors? Iliopsoas Rectus Femoris Sartorius Pectineus Name the primary hip extensors? Gluteus Maximus Biceps Femoris Semitendinosus Semimembranosus External Rotators This figure represents which movement of hip joint? Internal Rotation Injury to the obturator nerve will affect which movement? Adduction If you are flexing the hip then which type of contraction will take place in hip extensors? Eccentric contraction If you maintain your lower limb in full hip flexion then what type of contraction will take place in hip flexors. Concentric contraction Contracture of hip adductor will lead to loss of which movement? Extension External Rotation
