Q

Pain numbness and tingling involving entire arm and hand esp fduring over head activities

A

thoracic outlet syndrome
I( compression of subclavian artery, Brachial plexus)

22
Q

external rotaion ( on both active and passive movement is restricetd in)

A

adhesive capsulitis

23
Q

most common cause of revision of THR

A

THR- total hip replacement
most common cause of revision- aseptic losseing ( radiolucent on Xray)

24
ottawa rule for ankle xray
unable to walk four weight bearing steps immediately or in ed bony tenderness fromm the tip of medial malleolus to 6cm of post border of tibia bony tenderness from tip of lateral malleolus to the lower 6cm of posterior border of fibula
25
chondrocalcinosis
seen i pseudo gout ass with wilsons, haemochromatosis, hypotyroidism Positively birefringent crystal of calcium pyrophosphate
26
GBS
ass with areflexia, opthalmoplegia, ataxia
27
MS
associated with brisk tenson reflexes
28
pain worse at medial calcaneal tuberosity
plantar fascitis, exacerbated by walking on tiptoe
29
L3
supplies senosry to anterior thigh positive femoral nerve strecth test weak hip adduction, knee extension and hip flexion reduced knee reflex
30
L4
supplies medial malleolus and and anterior knee positive femoral stretch test reduced knee reflex weak hip adduction and knee extension
31
L5
supplies dorsum of foot weakness of dorsiflexion and and big toe dorsiflexion positive sciatic nerve strecth test reflexes intact
32
S1
supplies lateral part of foot and posterolateral leg weak planterflexion reduced ankle reflex Positive sciatic nerve stretch test
33
MX of ankylosing spondylitis
NSAIDs
34
obturator nerve
thigh adduction, sesnory nerve supply to medial thigh, can be inured due to ant hip disloaction
35
Femoral nerve
supplies ant and medial part of thigh an leg ( sensory) motor- knee extension thigh flexio
36
common peroneal nerve
injury can cause foot drop causes dorsiflexion of dorsum of foot and eversion
37
tibial nerve
causes planterflexion and inversion sensory sole of foot < not commomly injured is deep and well protected
38
Other associated aocnidtions with Ankylosing spondylitis
Apical fibrosis Achilles tenodnitis AV block anterior uveitis aortic regurg amyloidosis Cauda equina
39
Hip disolocation
occurs in RTA Posterior: More common than anterior, leg internally roateted , adducted and shortened Anterior- Abudcted and externally rotated needs to be corrected within 4 hours
40
Gout Acute Mx
NSAIDS Colchicine ( can cause diaarhea)
41
URate loweing therapy
offered to all patients after first attack 2 weeks after acute attack 1) allopurinol 2) febuxostat ( xanthine oxidase inhibitor) 2) uricase# 3)
42
SITS muscles
Subscaopularis- placed ant on chest. helps with internal rotation of shoulder supraspinatus_ positioned on top of your shoulder, helps with initial abductiom Infraspinaturs-helps in external rotation Teres inor-ext rotation
43
Meralgia parasthetica
burning in anterolateral aspect of thigh due to compression of lateral cutaneous nerve of thigh
44
after 5 years of oral bisphosphonates or 3 years of IV zoledronate, reassess
high risk age >75 On gluco-corticoid Tx Vertebral fracture/ hip fracture high risk on FRAX scoring T score <-2.5 after treatment if no high risk, stop Bisphosphonates and reassess in 2 year or if another frcture occurs
45
PTH, ALP
osteoporisis- PTH ,ALP, Calcium, PO4 all normal Osteomalacia- Ca, PO4 Decreased, ALP raised, PTH raised Primary PTH- Ca, PTH, ALP raised, PO4 decreased Sec Hyper PTH ( eg CKD)- Ca decreased, ALP, PO4, PTH raised Pagets disease- Ca, PO4 , PTH normal, ALP raised
46
Nerve supplies
