Q

Femoral triangle border

Study These Flashcards
A

Superior: Inguinal ligament
Medial: adductor longus
Lateral: sartorius

20
Q

Femoral triangle content medial to lateral

Study These Flashcards
A

Femoral vein (intermediate compartment of sheath), femoral artery (lateral compartment of shear), femoral nerve

21
Q

Femoral artery pathway

Study These Flashcards
A

Passes inguinal ligament where it turns from external iliac to femoral artery
Passes through triangle and through adductor canal
Through hiatus and then changes to popliteal artery

22
Q

Deep femoral artery branches

Study These Flashcards
A
  • Lateral and medial circumflex arteries circles around proximal end of femur
  • 4 perforating arteries that pass through adductor magnus insertion
23
Q

Saphenus nerve

Study These Flashcards
A

Splits from femoral nerve near femoral triangle and travels medially. Crosses knee joint and enters leg on medial side

24
Q

Obturator nerve

Study These Flashcards
A

Mixed nerve from L2,3,4
Anterior branch (anterior to adductor brevis)
- sensory: middle 1/3 of medial thigh
- motor: adductor muscles aside from Magnus and obturator externus
Posterior branch: posterior to brevis
- motor: adductor Magnus and obturator externus

25
Biceps femoris Long head
O: ischial tuberosity I: head of fibula I: tibial division F: prime mover knee flexion, some hip extension and when knee is flexed, lateral tibial rotation
26
Biceps femoral Short head
O: shaft of femur I: head of fibula I: common fibular division F: prime mover knee flexion, some hip extension and when knee is flexed, lateral tibial rotation
27
Semi tendinosus
O: ischial tuberosity I: medial condyle of tibia (pes anserine) I: tibial division F: flex knee and extension of hip. When knee flexed, medial knee rotation
28
Semi membranosus
O: ischial tuberosity I: shallow groove medial to medial Condyle of tibia I: tibial division F: flex knee and extension of hip. When knee flexed, medial knee rotation
29
Politeus
O; lat epicondlye of femur I: posterior tibia above soleal line I: tibial div F: open chain: med knee rotation Closed chain: femur lateral rotation and assist in knee flexion
30
Bifurcation of sciatic nerve
Junction of Proximal 2/3 and distal 1/3 on posterior thigh
31
Head of femur blood supply
Medial and lateral circumflex femoral arteries
32
Most important blood supply to posterior thigh
Perforating arteries from deep Femoral artery - penetrate through adductor Magnus
33
Knee joint type and articulating surfaces
Synovial joint 1. Tibiofemoral joint - tibial plate and femoral condyle (modified hinge joint) 2. Patelo femoral- patellar groove and posterior aspect of patella (planar joint)
34
Extrinsic knee ligaments
Patellar - from patella to tibial tuberosity Medial collateral ligament - medial femoral epicondyle to medial proximal tibia - some fibers blend with capsule LCL- lateral epicondle to head of fibula PCL- posterior intercondylar area to medial femoral condyle ACL - anterior intercondylar area to lateral femoral condyke
35
Function of ACL & PCL
Antero posterior stability PCL: prevent posterior glide of tibia against femur Ant: prevent anterior glide of tibia against femur
36
Menisci attachments
Anterior and posterior Horns are only bony attachment of menisci Both anterior horns are attached to transverse ligament Medial menisci : attached to fibrous capsule of joint (and therefore indirect attachment to MCL) Lateral meniscus: attached to popliteus tendon
37
Movement of menisci
Lateral glides 2x as much as medial meniscus (can accommodate better and therefore less injured)
38
Meniscus function
In extension: shock absorbers Flexion: increase congruency between convex posterior femur and flat tibial plate
39
Which muscles provides posterior knee stability
Popliteus - pulls lateral meniscus posterior in flexion to prevent impingement
40
Most stable knee position
Extension - MCL and LCL become stretched and stable when knee is laterally rotated and extended - medial rotation increases stretch and stability in cruciate ligaments
41
Supra patellar bursa
Extension of synovial membrane - articularis genus pulls this up in knee extension to prevent impingement
42
Support of knee fibrous membrane
Medial: MCL (attached to capsule) Lateral: LCL (not attached) and ITB (some attachment) Post: oblique popliteal ligament (extension of semi membranous tendon) and Ant: quad tendon
43
Knee joint gliding vs rotation in flexion
0-20 degrees of flexion = rolling 20-90: rolling gradually relaxed by gliding 90+ : gliding (comes with increased friction and OA risk)
44
Proximal tibio fibular joint ligaments
Joint between head of fibula and fibular facet on tibia Support: Anterior and posterior ligament Interosseous membrane
45
Poplietal fossa borders
Superior med: semi mebranosus and tendinosus Superior lat: biceps femoris Inferior lat: lat gastric and plantar Inferior med: medial gastroc head
46
Popliteal fossa content
Tibial nerve (most superficial) Common fibular nerve Popliteal vein (mid layer) Popliteal artery (deepest)
47
What makes the Sural nerve
Communicating sural from common fibular division and medial sural nerve from tibial division
