at the back of knee joint

reflection of semimembranous

27
Q

menisci of knee joint

A

lateral meniscus
medial meniscus
Lateral menisci more promiment, deeps the ‘hole’ more than medially

28
Q

GREY

flexors of hip

GREY

abduct hip

A

glut med, glut min, tensor fascia latae

31
Q

GREY

adduct hip

A

medial compartment (minus obturator internus) aka the adductors + gracilis

32
Q

GREY

rotate hip medially

A

glut med n glut min

33
Q

GREY

rotate hip laterally

A

deep muscles of gluteal region

= piriformis, obturator internus, superior gamellus, inferior gamellus, quadratus femoris

34
Q

GREY

flex knee

A

hamstrings, gracillis, satorius, gastrocnemius

35
Q

GREY

extend knee

A

quadriceps femoris

36
Q

GREY

rotate knee medially

A

semimtendinosus, semimembranosus

37
Q

GREY

rotate laterally

A

biceps femoris

38
Q

unhappy triad

A

anterior cruciate ACL
medial collateral MCL
medial meniscus

39
Q

intramuscular injectsion

A

to avoid sciatic nerve

40
Q

INJURY TO COMMON FIBULAR (PERONEAL) NERVE

A

due to injury/trauma at head of fibula that compresses the nerve
• Patient wont be able to evert the foot.
• and gets foot drop (cos cant dorsifelx at ankle)

41
Q

INJURY TO TIBIAL NERVE

A

patient cant plantarflexion + hav weakened inversion of foot (leading to shuffling gait)

42
Q

femoral nerve lesion

A

mite get
wasting of quadriceps
weakness in leg extension
weakness in thigh flexion

43
Q

obturator nerve issue

A

weakness in adduction

44
Q

midpnt of inguinal ligament from ASIS to pubic tubercle

A

to get u nerve

45
Q

mid inguinal line (mid pnt of the inguinal line)-from asis to pubic symphesis

A

to get artery

46
Q

fracture at proximal femur

A

distal fragment is pulled upwards and rotated laterally

leg gets shortened n laterally rotated

47
Q

garden of femoral neck fractures

A

garden I= incomplete fracture through neck
II= complete fracture but still stuck togez
III=complete fracture n partially displaced
IV= complete fracture n completely displaced

48
Q

femoral nerve palsy could get in

A

femorla shaft fracture

49
Q

DISTAL FEMUR INJURIES

A

• Condyle separation à joint misalignment
– What structure is vulnerable to injury?-femoral artery
• Long recovery period

50
Q

posterior knee dislocation

A

in car or hyperextension of knee

may damage popliteal artery

51
Q

posterior cruciate ligament injury

A

in car or hyperflexion

52
Q

great saphenous injury

A

Can become varicose (swollen, twisted and lengthened) ,

can thrombose. Which can lead to a deep vein thrombosis

53
Q

SUPERIOR GLUTEAL NERVE INJURY

A
  • Hip dislocation/subluxation, greater trochanter fracture

* get positive Trendelenburg test (pelvis on unsupported side descends) or swing-out gait

54
Q

Risk of strangulation of herniated section of bowel

A

blcoks blood supply to part of the bowel-=necrosis =>gangrene.

55
Q

A

occurring in the groin

56
Q

Femoral hernia

A

occurring high on the thigh, where the leg joins the body, just below inguinal ligament

57
Q

Patellar dislocation

A

• Lateral – what normally counteracts lateral pull on patella? Vastus medialis

58
Q

popping” sound

59
Q

PCL tear:

A

• OCCURS WEN LEG IS FLEXED AT THIGH, n FORCE PUSHES POSTEIRORLY,

60
