Term
How do you know which way the hip is oriented?
Definition
The ischial spine and the greater sciatic notch are always posterior. Remember that "spine" means posterior.
Term
What fits in the sciatic notch? What is the clinical relevance of it?

How are some ways the "very tough" ASIS can be damaged?
Definition
Football/contact sports, car wrecks
Term
Explain a ramus? What is the clinical relevance?
Definition
It is a large, rough area that has a huge angle. It is important to see how things are attached to that area.
Term
What nerve goes through obturator foramen? What does it innervate?
Definition
Obturator nerve. Medial aspect of thigh and femur.
Term
Name two important deep ligaments in the pelvic skeleton.
Definition
1. Sacrospinous (deeper & transverse)
2. Sacrotuberous (superficial & oblique)
Term
Distinguish between locations of the greater sciatic foramen and lesser sciatic foramen.
Definition
The greater sciatic foramen is superior and lesser sciatic foramen is inferior. They are separated by the Sacrospinous ligament.
Term
The Iliofemoral Ligament (a deep anterior ligament) goes from where? What is its purpose?
Definition
Ilium to femur. It strengthens the joint capsule.
Term
What is another deep anterior ligament that stretches from the pubis to the femur?
Definition
Pubofemoral.
Term
How many degrees does the labrum surround the joint?
Definition
360
Term
Name the coverings from deep to superficial beginning with labrum.
Definition
Labrum, joint capsule, ligaments, muscle/bursa (can be in between or superficial with ligaments/muscle), fascia,
Term
Name the three compartments of the thigh. What muscles do they contain?
Definition
Anterior - knee extensor muscles - quadriceps femoris
Posterior - knee flexor muscles - semimembranosus, semitendinosus, biceps femoris
Medial - adductor muscles - sartorius, adductor longus, adductor brevis, gracilis, adductor magnus
Term
If you extend the lower leg, what do you do at the hip?
Definition
Flex
Term
In the deep anterior muscles, psoas major & minor what is superior & smaller?
Definition
Psoas minor
Term
Should you look at the tendons to identify the muscles?
Definition
Yes
Term
Of the Adductor muscles, which one has 2 tendons & 3 distal insertions?
Definition
Adductor Magnus
Term
What muscle is used to repair anterior cruciate ligament damage?
Definition
Gracilis
Term
What muscles are used in internal rotation of the hip? External rotation?
Definition
Internal - Adductor Brevis & Adductor Longus
External - Adductor Magnus
Term
Pes anserinus is the attachment point for what muscle and what 2 tendons? What is the clinical importance? ** He said we will see this again!
Definition
Sartorius muscle, Gracilis & Semitendinosis tendon. 3 major attachments at one insertion point and the area they use to replace other ligaments.
Term
Where does the IT band attach to (lateral side)? Why is it clinically relevant?
Definition
Gerties tubercle. IT band stabilizes the femur.
Term
If the IT band starts hurting while you are jogging, what should you do?
Definition
Run faster!
Term
What is the longest muscle in the body? What is its function?
Definition
Sartorius. It flexes the thigh and externally rotates the legs.**Mentioned this twice in a row.
Term
Vastus means? Rectus means?
Definition
Large.
Straight.
Term
Rectus femoris helps us determine what?
Definition
Health of a patient. Ultrasound is done on this area, if this area is measured, it tells a lot about a person.
Term
What is one of the strongest muscles in the human body, other than the heart?
Definition
Gluteus maximus. Extends thigh and assists in external rotation of the hip.
Term
Name the action of the gluteus medius.
Definition
Abducting the leg & femur, and internal rotation of the hip.
Term
Trendelenberg gait is?
Definition
The Trendelenburg gait pattern)is an abnormal gait (as with walking) caused by weakness of the abductor muscles of the lower limb, gluteus medius and gluteus minimus. People with a lesion of superior gluteal nerve have weakness of abducting the thigh at the hip. This type of gait may also be seen in L5 radiculopathy and after poliomyelitis, but is then usually seen in combination with foot drop.
Term
Piriformis muscle actions are?
Definition
Stabilize the thigh and external rotation.
Term
Some people's sciatic nerve goes directly through which muscle?
Definition
Piriformis
Term

Definition
Piriformis
Term

Definition
Tibial nerve & common fibular division (2 branches: deep & superficial)
Term
Identify the movements of the knee and the degree to which it can move.
Definition
Flexion 120-150°
Extension 5-10°
Internal rotation 10°
External rotation 30-40°
