USMLE Step 2 CK Musculoskeletal & Orthopedics Study Guide 2026: High-Yield Topics, Clinical Vignettes and Exam Strategy

You've mastered cardiology, crushed pulmonology, and dominated infectious diseases. Now comes the MSK block — and honestly, it feels different. Unlike other Step 2 CK systems where pattern recognition rules, musculoskeletal medicine demands surgical thinking mixed with medical management. One vignette asks you to differentiate septic arthritis from crystal arthropathy (medical), the next wants you to know when a scaphoid fracture needs surgical fixation (surgical).

Here's what makes MSK challenging: the exam spans pediatric orthopedics, adult trauma, rheumatology, sports medicine, and oncology. A 45-year-old with knee pain could be osteoarthritis, meniscus tear, or osteosarcoma. The demographics, mechanism, and imaging details matter — miss one clue and you pick the wrong answer.

This guide breaks down the 47 highest-yield MSK topics for Step 2 CK, the clinical vignette patterns you'll see, and the exam strategy that converts study time into points. We'll walk through fracture classifications, arthritis differentials, and the pediatric orthopedic conditions that show up every single exam cycle.

How MSK Appears on USMLE Step 2 CK vs Step 1

Step 1 tested MSK pathophysiology — you memorized osteoblast vs osteoclast functions and growth plate anatomy. Step 2 CK tests clinical decision-making. You'll see 8-12 MSK questions (roughly 3% of the exam), and they fall into three categories:

Trauma/Emergency (40% of MSK questions): Compartment syndrome, open fractures, cauda equina syndrome, septic arthritis. These test your ability to recognize surgical emergencies and know the immediate next step. Chronic Conditions (35%): Osteoarthritis vs rheumatoid arthritis vs crystal arthropathy differentials, back pain workup (herniated disc vs spinal stenosis), bone tumors in different age groups. Pediatric Orthopedics (25%): Developmental dysplasia of the hip (DDH), slipped capital femoral epiphysis (SCFE), Legg-Calve-Perthes disease, and Osgood-Schlatter disease. Age demographics are key here.

The questions are longer than Step 1 — expect 4-6 sentences with specific imaging findings described in text (since they can't show actual X-rays). Time management becomes crucial when you're parsing "comminuted fracture of the distal radius with dorsal angulation" while the clock ticks.

High-Yield Fracture Patterns and Mechanisms

Fractures make up 30% of Step 2 CK MSK questions, and the exam loves eponymous fractures with specific mechanisms. Here are the must-know patterns:

Wrist and Forearm Fractures

Colles Fracture: Most common wrist fracture. Mechanism: fall on outstretched hand (FOOSH). X-ray finding: distal radius fracture with dorsal angulation ("dinner fork deformity"). Demographics: postmenopausal women. Treatment: closed reduction and casting for nondisplaced, surgical fixation for displaced. Smith Fracture: Less common but high-yield. Mechanism: fall on flexed wrist. X-ray: distal radius fracture with volar angulation (opposite of Colles). Always requires surgical fixation due to instability. Scaphoid Fracture: High-yield because it's commonly missed. Mechanism: FOOSH with radial deviation. Clinical finding: tenderness in anatomical snuffbox. X-ray: often normal initially (15% false negative rate). Key point: if clinically suspected, treat with thumb spica cast even with negative X-ray. Oncourse's spaced repetition flashcards surface these fracture patterns when you need to review them, preventing the "I studied this last month" memory gaps that cost points.

Hip Fractures

Femoral Neck vs Intertrochanteric: Age: >65 years. Mechanism: low-energy fall. Clinical: shortened, externally rotated leg with inability to bear weight.

Key differential: femoral neck fractures disrupt blood supply (risk of avascular necrosis), while intertrochanteric fractures maintain blood supply. Treatment: femoral neck gets hemiarthroplasty or total hip replacement; intertrochanteric gets ORIF with intramedullary nail.

Stress Fractures: High-yield in young athletes. Classic scenario: military recruit with hip pain and normal X-ray. MRI shows fracture line. Treatment: activity modification and gradual return to weight-bearing.

Vertebral Compression Fractures

Demographics: osteoporotic women >70. Mechanism: minimal trauma (coughing, bending forward). Clinical: acute back pain, kyphotic deformity. X-ray: "wedge-shaped" vertebral body on lateral view. Red flags for malignancy: age <50, weight loss, neurologic symptoms.

Arthritis Differentials: The Step 2 CK Classics

Arthritis questions appear in 25% of MSK vignettes, and the exam tests your ability to differentiate based on demographics, joint involvement, lab findings, and synovial fluid analysis.

Crystal Arthropathy vs Septic Arthritis

This is the highest-yield arthritis differential on Step 2 CK. Both present with acute monoarticular arthritis, but the labs and demographics differ:

Gout:

• Demographics: middle-aged men, history of alcohol use or diuretics

• Joint: first metatarsophalangeal joint (70% of initial episodes)

• Labs: elevated uric acid (but normal during acute attack in 30%)

• Synovial fluid: WBC 2,000-50,000, needle-shaped uric acid crystals, negative polarization

• Treatment: NSAIDs, colchicine, or corticosteroids

Pseudogout (CPPD):

• Demographics: elderly patients, often with prior knee surgery

• Joint: knee (50%), wrist, ankle

• Labs: normal uric acid

• Synovial fluid: WBC 2,000-50,000, rectangular calcium pyrophosphate crystals, positive polarization

• X-ray: chondrocalcinosis (calcification of menisci/joint capsules)

Septic Arthritis:

• Demographics: any age, but higher risk with diabetes, immunosuppression, prosthetic joints

• Joint: knee (50%), then hip, shoulder, ankle

• Labs: elevated ESR/CRP, blood cultures positive in 50%

• Synovial fluid: WBC >100,000 (85% polymorphs), positive gram stain/culture

• Treatment: immediate arthrocentesis + IV antibiotics, surgical drainage for hip/shoulder

When a vignette describes acute knee pain, use the synovial fluid WBC count as your discriminator: >100,000 = septic until proven otherwise.

Osteoarthritis vs Rheumatoid Arthritis

Osteoarthritis:

• Demographics: >50 years, female predominance

• Joints: weight-bearing joints (knees, hips), DIP/PIP joints of hands

• Pattern: asymmetric joint involvement

• Labs: normal ESR/CRP, negative rheumatoid factor

• X-ray: joint space narrowing, osteophytes, subchondral sclerosis

• Treatment: NSAIDs, weight loss, physical therapy; intra-articular corticosteroids for flares

Rheumatoid Arthritis:

• Demographics: 30-50 years, female 3:1 predominance

• Joints: MCP/PIP joints (spares DIPs), wrists, knees; symmetric involvement

• Pattern: morning stiffness >1 hour, improvement with activity

• Labs: elevated ESR/CRP, positive rheumatoid factor (70%), positive anti-CCP antibodies (95% specific)

• X-ray: joint space narrowing, marginal erosions, osteopenia

• Treatment: methotrexate + short-term corticosteroids, biologics for severe disease

Compartment Syndrome: The MSK Emergency

Compartment syndrome accounts for 15% of MSK emergency questions and tests your ability to recognize a surgical emergency based on clinical findings.

Mechanism: Increased pressure within fascial compartments, most commonly after tibial fractures, crush injuries, or prolonged compression. Clinical Findings (5 P's): Pain (especially passive stretch), Pallor, Paresthesias, Paralysis, Pulselessness. But here's the key: pulselessness is a late finding. If you wait for absent pulses, you've waited too long. Highest Yield Clinical Sign: Pain with passive stretch of muscles in the affected compartment. For forearm compartment syndrome, passive finger extension causes severe pain. For leg compartment syndrome, passive toe dorsiflexion causes severe pain. Diagnosis: Compartment pressure >30 mmHg or delta pressure <30 mmHg (difference between diastolic BP and compartment pressure). But don't wait for pressure measurements if clinical suspicion is high. Treatment: Immediate fasciotomy. This is a surgical emergency — delayed treatment leads to muscle necrosis, contractures, and limb loss.

Step 2 CK vignette pattern: young patient with tibial fracture, increasing pain despite adequate analgesia, pain with passive toe movement. Next best step: emergent fasciotomy.

Bone Tumors: Age Demographics Drive Diagnosis

Bone tumor questions appear in 10% of MSK vignettes, and age is the strongest predictor of tumor type. The exam tests your knowledge of which tumors occur in which decades.

Primary Bone Tumors by Age

Ages 10-20: Osteosarcoma and Ewing Sarcoma Osteosarcoma:

• Demographics: adolescent growth spurt, male predominance

• Location: metaphysis of long bones (distal femur 40%, proximal tibia 20%)

• X-ray: mixed sclerotic/lytic lesion with "sunburst" pattern, soft tissue mass

• Labs: elevated alkaline phosphatase, elevated LDH

• Treatment: neoadjuvant chemotherapy + limb salvage surgery

Ewing Sarcoma:

• Demographics: age 10-20, slight male predominance

• Location: diaphysis of long bones, flat bones (pelvis, ribs)

• X-ray: "onion skin" periosteal reaction, soft tissue mass

• Labs: normal alkaline phosphatase, elevated ESR

• Treatment: chemotherapy + radiation ± surgery

Ages 20-40: Giant Cell Tumor and Chondrosarcoma

Giant Cell Tumor:

• Location: epiphysis of long bones (distal femur, proximal tibia)

• X-ray: "soap bubble" lytic lesion extending to subchondral bone

• Treatment: curettage and bone grafting

Chondrosarcoma:

• Location: axial skeleton (pelvis, ribs, scapula)

• X-ray: chondroid matrix calcification ("rings and arcs")

• Treatment: wide surgical resection (resistant to chemo/radiation)

Ages >40: Metastatic Disease

Most Common Primary Sites: Breast, lung, kidney, thyroid, prostate ("BLT with a Kosher Pickle"). Imaging Patterns:

• Blastic metastases: prostate, breast

• Lytic metastases: lung, kidney, thyroid

• Mixed: breast

When a Step 2 CK vignette presents a >50-year-old with bone pain and a lesion on imaging, think metastatic disease first. Order bone scan to assess for multiple lesions, then search for primary tumor.

Back Pain: Surgical vs Medical Management

Back pain questions test your ability to differentiate mechanical causes (herniated disc, spinal stenosis) from medical causes (compression fracture, malignancy) and know when surgical intervention is indicated.

Herniated Disc vs Spinal Stenosis

Herniated Disc:

• Demographics: 30-50 years, often with lifting/twisting injury

• Clinical: radicular pain worse with sitting/bending forward, positive straight leg raise

• Level: L5-S1 (45%) causes weakness of plantar flexion and loss of Achilles reflex; L4-L5 (35%) causes foot drop and decreased sensation in first web space

• MRI: disc herniation with nerve root compression

• Treatment: NSAIDs + physical therapy initially, steroid injection for persistent symptoms, surgery if progressive weakness or >6 weeks of symptoms

Spinal Stenosis:

• Demographics: >60 years, often bilateral symptoms

• Clinical: neurogenic claudication (leg pain with walking, relieved by sitting/flexing forward), "shopping cart sign" (can walk further when leaning on cart)

• MRI: central canal narrowing <10mm, ligamentum flavum hypertrophy

• Treatment: physical therapy, epidural steroid injections, laminectomy for severe symptoms

Cauda Equina Syndrome: The Neurosurgical Emergency

Clinical Findings: Bilateral leg pain/weakness, saddle anesthesia, bowel/bladder dysfunction (retention > incontinence initially). Mechanism: Central disc herniation, epidural abscess, or tumor compression below L2. Treatment: Emergent MRI + neurosurgical decompression within 24 hours. Delayed treatment leads to permanent neurologic deficits.

Oncourse's AI tutor helps you nail these differentials by explaining exactly which clinical clue you missed when you select "herniated disc" for a spinal stenosis case. Instead of just seeing the right answer, you understand why "shopping cart sign" points specifically to stenosis, converting your miss into pattern recognition for the next similar vignette.

Pediatric Orthopedics: Age-Based Pattern Recognition

Pediatric orthopedic questions appear in 20% of MSK vignettes and rely heavily on age demographics. The exam tests your knowledge of which conditions occur in which age groups and when surgical intervention is indicated.

Hip Disorders by Age

Developmental Dysplasia of Hip (DDH):

• Age: newborn to 6 months

• Risk factors: female, breech presentation, family history, firstborn

• Clinical: asymmetric hip abduction, Galeazzi sign (unequal knee heights), positive Barlow/Ortolani tests

• Imaging: ultrasound <6 months, X-ray >6 months

• Treatment: Pavlik harness <6 months, surgical reduction if diagnosed late

Legg-Calve-Perthes Disease:

• Age: 4-8 years (peak age 6)

• Demographics: male 4:1, bilateral in 10%

• Pathophysiology: avascular necrosis of femoral head

• Clinical: limp, hip/knee pain worse with activity

• X-ray: sclerosis and flattening of femoral head

• Treatment: activity modification, abduction bracing, surgery for severe cases

Slipped Capital Femoral Epiphysis (SCFE):

• Age: 10-16 years (during growth spurt)

• Demographics: overweight boys, African American predominance

• Clinical: hip/knee pain, externally rotated leg, limp

• X-ray: "ice cream falling off the cone" on lateral view

• Treatment: immediate surgical pinning to prevent further slippage

Knee Pain in Adolescents

Osgood-Schlatter Disease:

• Age: 10-15 years during growth spurt

• Demographics: active adolescents (jumping sports)

• Clinical: anterior knee pain, tenderness over tibial tuberosity

• X-ray: fragmentation of tibial tuberosity

• Treatment: activity modification, NSAIDs, stretching; resolves with skeletal maturity

The key to pediatric orthopedic questions is age + mechanism. A 6-year-old with hip pain = Legg-Calve-Perthes. A 14-year-old obese boy with hip pain = SCFE. A 13-year-old basketball player with knee pain = Osgood-Schlatter.

Sports Medicine: ACL Tears and Rotator Cuff Injuries

Sports medicine questions focus on knee and shoulder injuries, testing your knowledge of specific examination maneuvers and treatment decisions.

Knee Injuries

ACL Tear:

• Mechanism: noncontact pivoting injury (basketball, soccer)

• Clinical: "pop" heard at injury, immediate swelling, positive Lachman test (most sensitive), positive anterior drawer test

• MRI: hyperintense signal in ACL, bone marrow edema

• Treatment: surgical reconstruction for young athletes, conservative for older sedentary patients

Meniscus Tear:

• Mechanism: twisting injury on planted foot

• Clinical: mechanical symptoms (locking, catching), joint line tenderness, positive McMurray test

• MRI: hyperintense signal extending to meniscal surface

• Treatment: arthroscopic repair for peripheral tears, meniscectomy for central tears

Shoulder Injuries

Rotator Cuff Tear:

• Demographics: >40 years, overhead athletes

• Clinical: shoulder pain worse with overhead activity, weakness with abduction, positive "empty can" test

• MRI: full-thickness vs partial-thickness tear

• Treatment: physical therapy initially, surgical repair for young patients with acute tears

Shoulder Impingement:

• Clinical: pain with overhead activity, positive Hawkins test, positive Neer sign

• Treatment: NSAIDs, physical therapy, subacromial corticosteroid injection

Practice sports medicine cases with detailed explanations to master the examination maneuvers and treatment algorithms.

Clinical Vignette Strategy: Dissecting MSK Questions

MSK vignettes follow predictable patterns. Here's how to systematically approach them:

Step 1: Extract Demographics and Mechanism

• Age (narrows differential significantly for bone tumors and pediatric conditions)

• Sex (males more likely for Legg-Calve-Perthes and SCFE, females for osteoporosis fractures)

• Mechanism (FOOSH = wrist fractures, twisting = ACL/meniscus, overhead activity = rotator cuff)

Step 2: Identify Key Clinical Findings

• Location of pain (first MTP = gout, heel = plantar fasciitis, groin = hip pathology)

• Quality of pain (mechanical = osteoarthritis, inflammatory = RA, radicular = disc herniation)

• Associated symptoms (fever = infection, weight loss = malignancy, bowel/bladder = cauda equina)

Step 3: Interpret Imaging Descriptions

Since Step 2 CK can't show actual images, they describe findings in text:

• "Sunburst pattern" = osteosarcoma

• "Onion skin appearance" = Ewing sarcoma

• "Joint space narrowing with osteophytes" = osteoarthritis

• "Marginal erosions" = rheumatoid arthritis

Step 4: Analyze Laboratory Data

• Synovial fluid WBC >100,000 = septic arthritis

• Uric acid crystals = gout (but uric acid level may be normal during acute attack)

• Elevated alkaline phosphatase in adolescent = consider osteosarcoma

• Elevated ESR/CRP with joint pain = inflammatory arthritis or infection

Step 5: Choose Management Based on Urgency

• Surgical emergencies: compartment syndrome, cauda equina, open fractures, septic arthritis

• Urgent referrals: progressive neurologic deficits, suspected malignancy

• Conservative management: most overuse injuries, stable fractures, degenerative conditions

Laboratory Interpretation in MSK Conditions

Understanding lab patterns helps differentiate similar conditions:

Inflammatory Markers

• Normal ESR/CRP: Osteoarthritis, mechanical back pain, stable chronic conditions

• Elevated ESR/CRP: Rheumatoid arthritis, septic arthritis, osteomyelitis, malignancy

Synovial Fluid Analysis

• WBC <2,000: Osteoarthritis, trauma

• WBC 2,000-50,000: Crystal arthropathy, inflammatory arthritis

• WBC >100,000: Septic arthritis (85% neutrophils)

Bone-Specific Markers

• Elevated Alkaline Phosphatase: Bone tumors (osteosarcoma), Paget disease, metastatic disease, growing adolescents

• Normal Alkaline Phosphatase: Ewing sarcoma (helps differentiate from osteosarcoma)

Common Step 2 CK MSK Traps and How to Avoid Them

Trap 1: Gout During Acute Attack

Uric acid levels are normal in 30% of patients during acute gout attacks. Don't rule out gout based on normal uric acid — use synovial fluid analysis for definitive diagnosis.

Trap 2: Scaphoid Fracture with Normal X-Ray

Initial X-rays are negative in 15% of scaphoid fractures. If clinical suspicion is high (anatomical snuffbox tenderness after FOOSH), treat with thumb spica cast and repeat X-rays in 2 weeks.

Trap 3: Compartment Syndrome with Present Pulses

Pulselessness is a late finding in compartment syndrome. Don't wait for absent pulses — the key finding is pain with passive muscle stretch.

Trap 4: Septic Arthritis in Prosthetic Joints

Septic arthritis in prosthetic joints may present more subtly than native joint infections. Even low-grade fever with joint pain warrants immediate evaluation.

Trap 5: Vertebral Compression Fractures in Young Patients

Compression fractures in patients <50 should raise concern for malignancy, not osteoporosis. Order MRI and search for primary tumor.

Time Management for MSK Questions

MSK questions are longer than average Step 2 CK questions due to detailed mechanism descriptions and imaging findings. Use these strategies:

30-Second Rule for Fractures

If the vignette describes a fracture, identify:

1. Location (wrist, hip, spine)

2. Mechanism (FOOSH, fall, high-energy trauma)

3. Age (osteoporotic vs young adult vs pediatric)

This immediately narrows your differential to 2-3 options.

Pattern Recognition for Arthritis

For joint pain vignettes:

1. Acute vs chronic (septic arthritis vs degenerative)

2. Mono vs polyarticular (crystal vs inflammatory)

3. Symmetric vs asymmetric (RA vs osteoarthritis)

Emergency vs Elective Decision Tree

MSK questions often test urgency of treatment:

• Emergent (next step: immediate surgery): Compartment syndrome, cauda equina, open fracture, septic arthritis

• Urgent (next step: referral within 24-48 hours): Closed fractures, progressive neurologic deficits

• Elective (next step: conservative treatment): Stable chronic conditions, overuse injuries

Use Oncourse's performance analytics to identify whether you're missing emergency cases (suggesting you need to memorize red flags) or overuse injuries (suggesting you need to review conservative management algorithms). This targeted feedback prevents broad, unfocused review sessions.

High-Yield MSK Mnemonics for Step 2 CK

Memory aids help consolidate the dense factual content in musculoskeletal medicine:

Bone Tumor Mnemonics

Age Groups: "CAGE" - Children (10-20): Ewing and Osteosarcoma; Adults (20-40): Giant cell and Chondrosarcoma; Golden years (>40): Metastatic disease Metastatic Sources: "BLT with a Kosher Pickle" - Breast, Lung, Thyroid, Kidney, Prostate

Compartment Syndrome (5 P's)

Pain, Pallor, Paresthesias, Paralysis, Pulselessness - but remember, pulselessness is late

Pediatric Hip Disorders by Age

"DDH at Diapers (0-6 months), LCP during License (4-8 years), SCFE during Sports (10-16 years)"

Crystal Arthropathy

Gout crystals: "Negatively birefringent Needle-shaped" (both start with N) Pseudogout crystals: "Positively birefringent Parallelogram-shaped" (both start with P)

Oncourse's mnemonic database surfaces these memory aids during your flashcard reviews, connecting abstract facts to memorable phrases. When you're reviewing bone tumors two weeks before your exam, seeing "BLT with a Kosher Pickle" instantly recalls the five most common primary sources of bone metastases.

Practice Question Patterns and Answer Strategies

Here are the most common Step 2 CK MSK question stems and how to approach them:

"Next Best Step" Questions

Trauma with obvious deformity: X-ray first (rule out fracture) Acute joint pain with fever: Arthrocentesis first (rule out septic arthritis) Back pain with neurologic symptoms: MRI first (rule out cord compression) Suspected compartment syndrome: Immediate fasciotomy (don't wait for pressure measurements)

"Most Likely Diagnosis" Questions

Use age as primary discriminator:

• 0-6 months with hip asymmetry: DDH

• 4-8 years with hip pain: Legg-Calve-Perthes

• 10-16 years obese with hip pain: SCFE

• >65 with hip pain after fall: Hip fracture

• >40 with bone lesion: Metastatic disease

"Best Initial Treatment" Questions

Conservative first: Overuse injuries, stable fractures, degenerative arthritis Surgical emergencies: Compartment syndrome, cauda equina, septic arthritis, open fractures Steroid injections: Trigger finger, carpal tunnel, subacromial impingement

MSK Question Bank Strategy

Effective question practice for MSK requires targeting specific weaknesses:

Week 1: Foundation Building

• Focus on high-yield topics: fractures, arthritis differentials, bone tumors

• Practice MSK questions with immediate review of explanations

• Build spaced repetition cards for eponymous fractures and pediatric age cutoffs

Week 2: Pattern Recognition

• Mixed MSK question sets to simulate exam conditions

• Focus on emergency vs non-emergency decision making

• Review imaging description interpretation

Week 3: Weakness Remediation

• Use performance analytics to identify specific gaps

• Target practice in weakest areas (emergency recognition vs chronic management)

• Final review of high-yield mnemonics and age-based differentials

Review bone tumor classifications using spaced repetition to ensure age demographics and tumor characteristics stick for exam day.

Integration with Other Step 2 CK Systems

MSK pathology appears in non-orthopedic contexts on Step 2 CK:

Internal Medicine Integration

• Rheumatoid arthritis: May present as constitutional symptoms before joint involvement

• Gout: Associated with diabetes, hypertension, metabolic syndrome

• Osteoporosis: Screen in postmenopausal women, initiate bisphosphonates

Emergency Medicine Integration

• Compartment syndrome: Often presents with polytrauma

• Septic arthritis: May present with sepsis, especially in immunocompromised

• Cauda equina: Neurologic emergency requiring immediate recognition

Pediatrics Integration

• Developmental milestones: When to refer for delayed walking

• Growth plate injuries: Salter-Harris classifications and growth implications

• Child abuse: Pattern of fractures suspicious for non-accidental trauma

Frequently Asked Questions

How many MSK questions can I expect on Step 2 CK?

Expect 8-12 MSK questions (roughly 3% of 280 total questions). They're distributed across internal medicine, surgery, emergency medicine, and pediatrics blocks, not grouped in a dedicated orthopedics section.

Should I memorize all fracture eponyms for Step 2 CK?

Focus on the highest-yield fractures with specific clinical implications: Colles, Smith, scaphoid, Jones, and Maisonneuve fractures. Skip rare eponyms that don't change management.

How detailed should my knowledge of surgical techniques be?

Step 2 CK tests decision-making (when to operate) not technical details (how to operate). Know indications for surgery, not specific surgical approaches.

What imaging findings are most important to recognize?

Focus on imaging descriptions rather than pattern recognition: "sunburst pattern" (osteosarcoma), "onion skin" (Ewing), "joint space narrowing with osteophytes" (osteoarthritis), "marginal erosions" (RA).

How do I differentiate pediatric hip disorders if age ranges overlap?

Use the peak age: DDH at birth, Legg-Calve-Perthes at age 6, SCFE at age 14. Also consider demographics: DDH in girls, LCP and SCFE in boys.

Should I focus more on traumatic or non-traumatic MSK conditions?

Both are equally important. Trauma questions test emergency recognition, while medical conditions test differential diagnosis skills. Balance your study time between both categories.

---

MSK medicine demands precision — the difference between compartment syndrome and muscle strain is immediate surgery vs rest. Between septic arthritis and gout is antibiotics vs anti-inflammatories. Master the demographics, recognize the emergencies, and differentiate the arthritis patterns.

The clinical vignettes test your systematic approach more than pure memorization. Age narrows bone tumor differentials. Mechanism predicts fracture patterns. Synovial fluid analysis distinguishes septic from crystal arthropathy. Lab values separate inflammatory from degenerative conditions.

Focus your remaining study time on emergency recognition, arthritis differentials, and pediatric age cutoffs. These three areas generate 70% of MSK points on Step 2 CK.
