Q

Most common femur injuries

A

Break at neck and break at intertrochanter. More serious is break at neck of femur as it’s a highly vasculated area.

A

Sartorius to medial border

22
Q

Medial Boundary of Thigh

A

Abductor Longus to Medial Border

23
Q

Superior Boundary of Thigh

A

Inguinal Ligament

24
Q

Floor (internal) Boundary of Thigh

A

Iliopsoas, pectineus and abductor longus

25
Q

Roof boundary of thigh

A

Fascia Lata

26
Q

Gluteal Regions Boundaries

A

Iliac Crest (superior) and Gluteal Fold (inferior)

27
Q

Gluteus Maximus Nerve Supply and Function

A

Nerve supply: inferior gluteal. Function: Hip extension (left to right) and lateral rotation (front to back)

28
Q

Tensor Flexers Nerve Supply and Function

A

Superior Gluteal. Hip abduction (moving away from body’s midline) and flexion (moving legs vertically up and down)

29
Q

Gluteus Medius Nerve Supply and Function

A

Superior Gluteal. Hip abduction and medial rotation

30
Q

Gluteus Miniums Nerve Supply and Function

A

Superior Gluteal. Hib abduction and medial rotation

31
Q

What prevents gait when standing

A

Medius and minimums work together to balance pelvis. Stabilizing hip joint

32
Q

How Trendelenburg Gate Occurs

A

Nerve damage/ weakened muscles means that Medius and minimus aren’t strong enough to counter balance direction of movement

33
Q

Components of Anterior Thigh and nerve supply

A

Sartorius, Iliopsoas, Quadriceps Femoris (all femoral nerve) and Tensor Fascia Lata (Superior Gluteal Nerve)

34
Q

Abductor Hiatus Outline

A

Femoral artery and vein pass through and become popliteal artery and vein

35
Q

State of meniscus at knee when standing

A

Flat

36
Q

State of meniscus at knee when sitting

A

Round

37
Q

What enables locking/unlocking of knee

A

Poplietus Tendon

38
Q

Cruciate Ligament

A

Anterior and posterior forms cross, increasing stability

39
Q

Knee Flexion

A

Posterior Thigh (hamstrings)

40
Q

Knee Extension

A

Quadriceps

41
Q

Tibiofibular Superior Joint

A

Synovial joint. Seperate from knee

42
Q

Tibiofibular Inferior Joint

A

Fibrous

43
Q

Where is weight carried in foot

44
Q

Talus Outline

A

Articulates superiorly with tibia/fibula and calcaneeus inferiorly

45
Q

Calcaneus Outline

A

Forms heel. Talus on superior surface. Attachment point for calcaneal temdon (achilles heel)

46
Q

Acronym for Tarsal Tunnel nerve and blood supply

A

Tom, Dick And Very Nervous Harry

47
Q

Tibialis Posterior (Tom) Function

A

Muscle in tarsal tunnel. Allows for ankle and foot movements

48
Q

Flexor Digitorm Longus (Dick) Outline

A

Muscle in tarsal tunnel for flexing of toes and feet

49
