✅ Correct Answer: C. Ankylosing spondylitis

---

🧠 Why this is correct:

The patient has classic findings of:

🔙 Chronic inflammatory back pain
🏃 Pain improves with exercise
🦴 Sacroiliitis
🫁 Reduced chest expansion
🧪 HLA-B27 positivity

👉 These findings strongly suggest:

Ankylosing spondylitis ⭐

It occurs due to:

🧬 Chronic inflammation at entheses and sacroiliac joints
➡️ Progressive spinal fusion develops
➡️ Reduced spinal mobility occurs

---

❌ Why others are wrong:

A. Rheumatoid arthritis

🖐️ Symmetrical small-joint arthritis common

❌ Sacroiliitis uncommon

B. Osteoarthritis

🦴 Degenerative joint disease

❌ Improves with rest, not exercise

D. Gout

💎 Acute monoarthritis common

❌ Chronic inflammatory back pain absent

🔑 Exam Trick:

🔙 Back pain in young adult
+
🏃 Better with exercise
+
🦴 Sacroiliitis
+
🧪 HLA-B27

= Think Ankylosing spondylitis immediately 🚨

⚠️ Characteristic X-ray finding:

Bamboo spine 🎋

🧪 Laboratory finding:

HLA-B27 positive

RF negative

💊 Treatment:

NSAIDs (first-line)

TNF-α inhibitors in severe disease
