Spinal Immobilization MCQ | Free NEET SS Surgery Question
Q) Out of the following, which patient requires spinal immobilization the most?
Answer: A. 22-year-old female involved in a high-speed motor vehicle collision with back pain

🔍 Explanation:
Spinal immobilization is most indicated when there's a high-risk mechanism of injury with suggestive symptoms, such as midline spinal pain or neurological signs.

A involves a high-energy mechanism (MVC) and reported back pain, which is a clear indication for spinal immobilization per NEXUS and Canadian C-spine rules.

B has a lower-risk mechanism and no symptoms; thus, spinal immobilization is generally not needed.

C – Gunshot wounds may or may not need spinal immobilization depending on location and neurological findings; not always indicated unless spinal structures are involved.

D – Isolated abdominal trauma is not an indication for spinal immobilization unless there’s evidence of spinal involvement.

Mechanism of Injury:
• Blunt trauma – Direct impingement, ischemia, compression or bleeding
• Penetrating trauma – Laceration of spinal cord

🩻 Chance fracture: A transverse fracture of all vertebral elements.

🩺 Management:
1. Complete immobilisation
2. Management of associated neurogenic shock (due to loss of sympathetic tone) with vasopressors and fluids

Questions on colon 21-30

Ans ) a PSC 

Arthritis,  ankylosing  spondylitis,  erythema  nodosum,  and  pyoderma  gangrenosum  typically  improve  or  completely  resolve after  colectomy.

PSC  occurs  in  5%  to  8%  of  patients  with  ulcerative  colitis. 

HLA-B8  or HLA-DR3  haplotype  are  10  times  more  likely  to  develop  PSC. 

The  risk  for  colon  cancer   in these  patients  is  up  to  five  times  greater   than  in  patients  with ulcerative  colitis  alone.  These  tumors  are  more  likely  to  arise proximal  to  the  splenic  flexure . Colectomy  has  no  effect  on  the course  of  PSC.
