Q.    Painful neuropathy and intact nerve anatomy is called ?

a. Neuralgia
b. Neuropathic pain
c. Neuropraxia
d. Neurostenalgia
e. Neuroma

Answer -
d
Continuous irritation of an anatomically intact nerve by a noxious stimulus leading to neuropathic pain is called neurostenalgia.

Common causes are , compression , distortion ,ischemia and tethering of nerve and immediate relief following removal of offending cause.

The difference between neuropraxia is that neuropraxia commonly are due to acute causes leading to transient nerve compressions and usually are not painful.

image Q. 102 - Stronger

Q.    Which of these is the strongest structure?

a. Meniscofemoral ligament
b. Anterior cruciate ligament
c. Posterior cruciate ligament
d. Collateral ligament
e. Ligamentum mucosum



 

























































































Answer -
c

Posterior cruciate ligament ( PCL) is the strongest ligament in knee.

Ligamentum mucosum is not true ligament.  It results from remnant of synovial folds or septum (plicae) inside knee of some individuals.
 Infrapatellar plica is associated with it.

image Q. 101 - Harness blues

Q.     Pavlik harness is kind of brace used in conservative treatment of DDH (Developmental Dysplasia of Hip). Complications of this harness Pavlik harness disease includes which of these?

a. Brachial plexus palsy
b. Osteonecrosis of femoral head
c. Femoral nerve palsy
d. Dislocation of femoral head
e. All of the above

Answer -
d

Pavlik harness is a dynamic flexion abduction orthosis.

All of the above are serious complications of Pavlik harness.

Abnormal posture within harness can occasionally cause inferior or obturator dislocation of hip.

 Shoulder straps can cause brachial plexus complications in some cases.

image Q. 100 - Fluidity

Q.   Fluid - fluid level is found in ?

a. Unicameral bone cyst
b. Intraoseous lipoma
c. intra isseous ganglion cyst
d. Aneurysmal bone cyst

Answer -
d
Fluid fluid level is characteristic feature seen in MRI of bone lesion suggesting aneurysmal bone cyst.

Some notable features of common bone neoplasm are given here :

Fallen fragment sign - Simple / Unicameral bone cyst.

Blade of grass/ Flame appearance - Paget disease.

Stippled / Pop corn/ Punctate calcification - Enchondroma

Jailhouse appearance - (stripe vertical lines in vertebra) - Hemangioma

Chicken wire appearance ( microscopy) - Chondroblastoma

Split fat sign (MRI) - Scwannoma

Presence of hemosiderin - Pigmented villonodular synovitis ( PVNS)

image Q. 99 - Multiplicity

Q.   Multiple neoplastic  lesion are features of all except ?

a. Ollier's disease
b. Maffucci syndrome
c. Jaffe - Campanacci syndrome
d. Albright syndrome
e. Mazabraud syndrome
f. All of the above

Answer -

Multiple Enchondroma are features of Ollier's disease and those associated with soft tissue hemangiomas are termed Maffucci's syndrome.

Albright syndrome consists of polyostotic fibrous dysplasia with cafe au lait spots with endocrinopathies.

Mazabraud syndrome consists of fibrous dysplasia usually polyostotic along with multiple soft tissue or intramuscular myxomas.

Polyostotic non ossifying fibroma are features of Jaffe Campanacci syndrome along with cafe au lait spots and axillary freckling among others.

image Q. 97 - Plastered

Q.   Which of these is common of all given complications during removal of plaster ?

a. Iatrogenic fracture
b. Pressure necrosis
c. Thermal burn
d. Skin erythema

Answer -
c

Thermal burn can be a common complication out of all other options.
Thermal burn results from inadvertent contact of plaster cutting saw ( motorised) into the skin.

As these saw do not usually give sharp incisive cuts, their rotational blades may produce heat and therefore thermal superficial burns.

Pressure complications are common complication but not that of removal of plaster.

Iatrogenic injuries may result due to excessive forceful technique but is relatively uncommon.
