General | 👁 7 | 2 weeks agoDiagnosis uses consensus criteria (MSIS/ICM) combining major and minor criteria. Classify by timing: early (24 mo) — guides biofilm maturity and strategy. Treatment options: DAIR (...
Arthroplasty | 👁 2 | 2 weeks agoClassically 24–72 h after long‑bone/pelvic fractures or IM reaming; triad: hypoxemia, neurological signs, petechiae. Diagnosis is clinical; supported by Gurd’s criteria (1 major +...
Trauma | 👁 4 | 2 weeks agoHeterotopic ossification in muscle after trauma or neurological injury. Common sites: quadriceps, brachialis, adductors. Symptoms: painful swelling → hard mass, ↓ROM. Radiology: pe...
Trauma | 👁 3 | 2 weeks agoAbsolute CP >30 mmHg indicates fasciotomy. ΔP = DBP – CP; if <30 mmHg, fasciotomy indicated. Interpret with clinical signs.
Trauma | 👁 11 | 2 weeks agoTension‑stress effect: gradual distraction (≈1 mm/day in 4 steps) after corticotomy induces regenerate bone and soft‑tissue adaptation. Circular fixator with tensioned wires permit...
Trauma | 👁 8 | 2 weeks agoTypes: uniplanar, biplanar, circular. Biomechanics: stiffness ↑ with larger pins, more pins, wider spread, closer frame. Indications: open fractures, polytrauma, infected nonunion,...

General | 👁 4 | 2 weeks agoRisk high in hip/knee arthroplasty, hip fracture surgery, pelvic/acetabular trauma, prolonged immobility. Options: LMWH, DOACs (apixaban/rivaroxaban), aspirin (selected low‑risk ar...
General | 👁 3 | 2 weeks agoPhases: inflammatory (days 1–7), proliferative (days 3–21), remodeling (weeks–months). Intrinsic (tenocyte) vs extrinsic (synovial/paratenon) healing; adhesion formation from extri...
General | 👁 4 | 2 weeks agoStage before biopsy: define lesion (X‑ray/MRI) and search for primaries (CT CAP, bone scan/PET). Adult common cause is metastasis (BLT KP) or myeloma; in children, benign lesions (...
