Anterior Medial Thigh Flashcards
What spinal nerves innervate the lateral femoral cutaneous N.
L2 and L3
What spinal nerves innervate the femoral N.
L2 - L4
What spinal nerves innervate the obturator N.
L2 - L4
What spinal nerves innervate the sciatic N. As well as the tibial N. And the common Fibular N.
Sciatic - L4 - S3
Tibila N. - L4 - S3
Common Fibular N. - L4. -S2
The patellar reflex tests the function of what
The absence of a reflex is known as what
The femoral N. As well as L2 - L4
The absence is known as Westphal’s sign
What does the calcaneal tendon reflex test
Tests S1 and S2 nerve roots
If the nerve root is cut or compressed, the ankle reflex is virtually absent
What is osgood-schlatter disease
A pulling away of quadriceps tendon from the tibial tuberosity
This usually occurs in kids and young adults
Healed by addition of new bone to the area
The part of muscle attachment superior to the patella is called what
The patellar tendon
The attachment point inferior to the patella is called what
Patellar L.
Define the adductor canal
A long, narrow passageway in the middle third of the thigh. This provides for an intermuscular passage for the femoral A./V., saphenous N., and the nerve of the vastus medialis
What are the borders of the adductor canal
Anterior/lateral by the vastus medialis
Posteriorly by the adductus longus and magnus
Medially by the sartorius which overlies the groove between and above muscles forming the roof of the cana
What type of fracture of the hip bones may occur during sports with a sudden acceleration or deceleration
An avulsion fracture of the hip bone where a small part of the bone with a piece of tendon or ligament is torn away
Where do avulsion fractures of the hip bone usually occur
At apophyses
What is coxa vara
The angle of inclination is decreased in the femur
What is coxa valga
The angle of inclination is increased
What is the most common type of fracture of the tibia
A compound fractures
What is a hip pointer injury
A contusion of the iliac crest that usually occurs at its anterior part where the sartorius attaches to the ASIS
Usually involved with collision sports
Where is the most common site of thigh hematoma
In the quadriceps
What is a charlie horse
Cramping of an individual thigh muscle due to ischemia or a contusion
What causes a psoas abcess
A retroperitoneal pyogenic infection in the abdomen or pelvis secondary to TB of the vertebral column
Can also be caused by regional enteritis of the ileum
Psoas abcess should always be considered when?
When there is edema in the proximal part of the thigh
Where can a psoas abscess be palpated
The inguinal region, just inferior or superior to the inguinal ligament
What are the S/S of a paralyzed quadriceps muscle
Patient can not extend the leg against resistance
Commonly walk with a forward lean, pressing on the distal end of the thigh with their hand as the heel contacts the ground to prevent flexion
Define chondromalacia patallae and give S/S
Known as runner’s knee
Is a softening of the articular cartilage of the patella
Due to an overstrethching of the knee region and a quadriceps imbalance
When does the patella ossify
3 - 6 yrs
Define bipartite or tripartite patella and what it can be mistaken for
Separate (2 or 3) parts of the patella due to an ossification abnormality
Can be mistaken for a patellar Fx.
Is always seen bi-laterally
What muscle of the leg can be removed and transplanted elsewhere to help with muscle injury
The gracilis
Define a groin pull and its S/S
A strain, stretching, and probably some tearing of the proximal attachments of the antetomedial thigh muscles have occurred.
Usually involves the flexor and adductor thigh muscles
Define rider’s strain
A muscle strain of the adductor longus M.
The anterior compt. Of the thigh contains what
The extensors and the fem. N.
The medial compt. Of the thigh contains what
The adductors and the obturator N.
The posterior compt. Of the thigh contains what
The flexors and the sciatic N.
What is the Des Anserius
A common site of insertion for 3 muscles
What 3 muscles insert to the Des Anserius and what N. Innervates them
Sartorius - Fem N.
Gracialis - Obturator N.
Semitendinosus - Tibial Div. of Sciatic N.
