Medical School MD + DO Mastery

A 4-year, board-aligned study system for medical school and licensing exams.

Walk the full Year 1–4 curriculum — foundational sciences, organ-system blocks, clinical clerkships and advanced practice — each with mastery checklists and linked learning resources, plus a dedicated review system for school exams, Shelf/COMAT, USMLE Step 1–3 and COMLEX-USA Levels 1–3.

MSK + BONE / JOINT FOUNDATIONS

YEAR 2 | PAGE 26A - MECHANICS, ARTHRITIS, METABOLIC BONE + TUMORS

MSK REASONING FRAME

STRUCTURE + BIOMECHANICS -> PAIN PATTERN -> RANGE OF MOTION / STRENGTH -> INFLAMMATION? -> IMAGING/LABS -> PATHOLOGY -> THERAPY. Decide mechanical vs inflammatory vs crystal/infectious vs neoplastic before naming a disease.

1.Muscle Mechanics: Contractions & Levers - Ninja Nerddeep mechanicsIsometric, concentric and eccentric contraction plus lever systems; connects muscle force to movement and common biomechanical exam reasoning.
2.Rotator Cuff Tear + Clinical Exam - Ninja Nerd~48 minShoulder anatomy, mechanisms of injury, exam maneuvers, imaging and management; a strong structure-to-clinical model for MSK reasoning.
3.Osteoarthritis - Osmosiscore arthritisDegenerative cartilage and subchondral bone disease; activity-related pain, exam/imaging patterns and management logic.
4.Gout - Osmosiscore crystalHyperuricemia, monosodium urate crystallization, acute inflammatory arthritis, crystal analysis and treatment principles.
5.Osteoporosis - Osmosiscore boneBone remodeling imbalance, fracture risk, DEXA concepts and antiresorptive/anabolic treatment mechanisms.
6.Bone Tumors - Osmosistumor patternAge, location, matrix and radiographic pattern approach to benign vs malignant primary bone tumors.

- Given joint pain, first state inflammatory vs mechanical vs crystal/infectious and defend the classification from stiffness duration, warmth/swelling, systemic features and activity pattern. - For a bone lesion, use AGE -> BONE/LOCATION -> MARGIN -> MATRIX -> periosteal reaction before choosing the tumor name. - For muscle weakness, separate true weakness from pain-limited motion and localize muscle, tendon, peripheral nerve, NMJ or systemic myopathy. - For every treatment question, connect the drug or intervention to the mechanism being corrected rather than memorizing a disease-drug pair.
