@DrAditya2935 Because of this issue, last year 2 seats went wasted in Nephrology, MMC which is one of the best in the country. This issue keeps happening every year :(

@spinesurgeon I think the seats for service quota remain vacant. If it all there is no one to pick those seats, it should be allocated for non service aspirants by merit. There are many non service candidates, willing to work hard.

RA (Rheumatoid Arthritis) vs OA (Osteoarthritis) joint involvement patterns

Students memorise "RA spares DIP, OA hits DIP" as random facts, then blank on which is which.

It's not random. Just ask: what tissue is the disease attacking?

RA attacks synovium. It's immune driven - a pannus grows out of synovial lining and eats the joint. So RA goes where synovium is in great density: the MCP (metacarpophalangeal/knuckle), PIP (proximal interphalangeal) and wrist. The DIP (distal interphalangeal) has little synovium, so it's spared. And since the trigger is systemic (circulating antibodies, cytokines), it hits both hands symmetrically.

Proof of the rule - in the spine, RA ignores everything except the atlantoaxial joint. Why? Discs aren't synovial; the atlantoaxial joint is! RA literally hunts synovium across the skeleton.

OA is different. It's cartilage breaking down under mechanical load - wear and tear, not immunity. So it follows wherever you grind/hardworking joint: the DIP (fine pinch), thumb base, knees, hips, spine. Being mechanical and local, it's often asymmetric - your dominant hand, your old injured knee.

Now the part students miss - which joints OA spare, and why. OA almost never touches the MCP, wrist, elbow or ankle. Look at the logic: these aren't built to take pure compressive load the way fingertips, knees and hips are. The ankle especially has tough, resilient cartilage and great congruence, so it resists wear beautifully. So if you see OA at the MCP, wrist or ankle, don't accept it at first sight - think secondary cause: haemochromatosis, CPPD (calcium pyrophosphate dihydrate deposition - pseudogout), old trauma.

@_Kratik_Agarwal Pixel did this years back. It can read contexts from screenshots. It’s ridiculous how iPhone doesn’t even allow to copy a particular word in whatsapp msg but as the entire message.
