Paper 2 notes (Batch 41) :

💥 Orthopedics
• Monteggia fracture = Fracture of ulna + radial head dislocation.
• Galeazzi fracture = Distal radius fracture + distal radioulnar joint dislocation.
• Smith’s fracture = Volar angulation of distal radius (flexion injury).
• Compartment syndrome = Pain, paresthesia, paralysis → emergency fasciotomy needed.
• Fat embolism = Confusion, hypoxia, petechiae post long bone fracture.
• External fixation = Best initial treatment for type III-B open tibial fractures.
• DVT = Most common post-fracture complication.
• Giant cell tumor = Epiphyseal, soap bubble appearance on X-ray.
• Pott’s spine = Tuberculosis of the vertebrae.
• Chronic osteomyelitis = Amyloidosis is a known complication.
❌ Trap: Treating open fractures with delayed wound closure (must debride + antibiotics early).

💥 Urology
• Posterior urethral valve (PUV) in neonates: Palpable bladder, renal failure, recurrent UTI; NOT hematuria.
• PUJ obstruction is often due to aberrant crossing vessels.
• Struvite stones = Magnesium ammonium phosphate → from urease-producing organisms.
• Bladder carcinoma = Often transitional cell type; painless hematuria.
• Undescended testis: Treated to preserve fertility, not just malignancy prevention.
• Testicular torsion = High-riding, horizontal testis → needs exploration.
• Right testicular vein drains to IVC, left to left renal vein.
• Renal oncocytoma = Central scar, no necrosis (unlike RCC).
• Renal trauma: CT with contrast is imaging of choice.
❌ Trap: BPH can’t be the cause of acute retention in a catheterized patient with empty bladder.

💥 ENT
• Angiofibroma: Nasal mass in adolescent males with recurrent epistaxis.
• Glue ear (secretory otitis media): MCC of bilateral CHL in kids.
• Otitis media with effusion: ABR not reliable; tympanometry preferred.
• Osteochondroma = Most common benign tumor of external auditory canal.
• Retropharyngeal abscess: Life-threatening → post-tonsillitis complication.
• Pott’s puffy tumor = Osteomyelitis of frontal sinus anterior wall.
• Sinus drainage: Posterior ethmoid + sphenoid → superior meatus.
• Tonsillitis complications = Include PTA, RPA, sepsis; NOT mastoiditis.


💥 Pediatrics
• PUV = Most common cause of lower urinary obstruction in boys; can cause stillbirth.
• Congenital diaphragmatic hernia (Bochdalek): Posterolateral defect (left side).
• Rectal suction biopsy = Diagnostic gold standard for Hirschsprung’s disease.
• Congenital hip dislocation → Galeazzi sign = femur length discrepancy.
• Testicular torsion = Common in adolescents; prompt exploration needed.
• Adenoid hypertrophy = Main symptom is mouth breathing.

💥 Plastic Surgery / Burns
• Burn severity = Assessed by TBSA (%), not just depth.
• Full-thickness grafts = Limited donor site; less contracture; cover smaller areas.
• Donor site = Needs proper care (NOT negligible).
• Burn shock = Caused by increased vascular permeability.

💥 Oncology & General Surgery
• Osteosarcoma = Metaphysis of long bones, sunburst appearance.
• Prostate cancer = Arises most commonly in the peripheral zone.
• TRUS = Most useful diagnostic test for prostate cancer.
• Granulomatous prostatitis → Autoimmune work-up required.
• Carcinoma of bladder = UTI-like symptoms, urgency, hematuria.
• Squamous cell carcinoma = Most common oropharyngeal cancer.
• Brain tumors = High-grade gliomas are most malignant.

💥 Anesthesia & Emergency
• Propofol = Drug of choice for day-case anesthesia (short acting, antiemetic).
• Local anesthetic toxicity: CNS effects → seizures precede CV collapse.
• Rapid sequence induction = For urgent surgery in non-fasting patients.
• Atropine = NOT used for sedation; midazolam preferred.
• Premed for IV anesthesia: Avoid hyoscine if CNS toxicity suspected.
❌ Trap: Methhemoglobinemia from prilocaine not seen with all LAs.

💥 Bonus Clinical Pearls
🧠 Mnemonic for epistaxis: "LITTLE area bleeds a LOT."
🧠 PUJ obstruction cause: “Crossing vessels obstruct the flow at the junction.”
🧠 Brain tumors → “High-grade = bad news.”
⚠️ Red flag: Delaying fasciotomy in compartment syndrome → limb loss.
