26 Sports Medicine
26.1 General Approach to the MSK Exam
- History
- Mechanism, chronicity, exposures, associated symptoms
- Red flags: B symptoms, major trauma
- Inspection: Compare to contralateral side. Make sure to EXPOSE for best exam.
- Look for asymmetry, atrophy, deformity, ecchymosis, erythema, scars
- Red flags: Erythema (sign of infxn), deformity concerning for major trauma
- Palpation
- Feel for anatomic points of interest
- Red flags: Warmth (sign of infxn), diminished sensation (sign of neurologic deficit)
- Range of motion (ROM): Active first, then passive
- Look for pain w/ motion, limited ROM (and distinguish whether due to pain, effusion, mechanical problem)
- Strength
- Graded from 0-5 out of 5:
- 5/5 = full strength
- 4/5 = movement against some resistance
- 3/5 = movement against gravity
- 2/5 = movement but not against gravity
- 1/5 = muscle flicker
- 0/5 = no contraction
- Red flags: Diminished strength if not due to pain (sign of neurologic deficit)
- Graded from 0-5 out of 5:
- Special testing is joint specific - see relevant sections below

26.3 Pre-Participation Physical
26.3.0.1 History
- Goal: Elucidate conditions that might preclude or limit sports participation
- Cardiac history
- Dyspnea on exertion → consider exercise induced asthma or vocal cord dysfunction
- History of head trauma
- History of “burners” or “stingers” (from transient brachial plexus compression/stretching) → if recurrent, may need C-spine XR
- Disordered eating (esp/ in sports w/ weight requirements)
- Substance abuse
- Family history: Sudden death, congenital heart disease, arrhythmias, Marfan syndrome
26.3.0.2 Physical Exam
Special attention to CV, resp, and MSK (assess ROM, symmetry, stability)
26.3.0.3 Cardiac Testing
- e.g. EKG, echo, exercise testing
- ONLY if clinically indicated, though highly controversial and recommendations worldwide differ. Current AHA/AAP PPE guidelines currently do not recommend global EKG/echo.
26.3.0.4 Clearance
- Increased risk of injury?
- Would treatment make athlete safe to participate?
- Can limited participation be allowed while treatment is undergone?
- Limitations for some or all sports?
26.4 Upper Extremity: Elbow, Forearm & Wrist
26.4.1 Anatomy
26.4.2 Exam Pearls
- Rapid elbow/forearm neurovascular exam:
- Brachial artery: Brachial + radial pulses, perfusion check
- Median nerve: Sensation over palmar side of digits 1-3
- Anterior interosseous nerve (motor-only branch of median nerve): “OK” sign 👌, grip strength
- Radial nerve: Wrist extension, thumbs-up sign 👍
- Ulnar nerve: Spread fingers against resistance
26.4.3 Supracondylar Fracture
26.4.3.1 Description/Mechanism
Usually fall on outstretched hand (FOOSH) with elbow hyperextension

26.4.4.1 Description/Mechanism
Traction on arm with extended elbow (e.g. swinging child through the air)
26.4.4.2 Diagnosis
- Exam: No deformity, elbow held in passive pronation with slight flexion, refusing to use arm
- Imaging: Unnecessary unless suspect fracture based on H&P, or if reduction unsuccessful
26.4.4.3 Management
Stabilize elbow w/ one hand → supinate forearm and flex elbow (will usually feel/hear click)
26.4.5 Distal Radius Fracture
26.4.5.1 Description/Mechanism
- FOOSH
- Most common pediatric fracture
26.4.5.2 Diagnosis

26.5 Upper Extremity: Shoulder
26.5.1 Anatomy

- Supraspinatus → Abduction
- Infraspinatus and Teres Minor → External rotation x2
- Subscapularis → Internal rotation
26.5.2 Exam Pearls & Special Tests
- Empty can test: Strength in internal rotation/thumb down position. Tests supraspinatus.
- Scarf test: Pain w/ cross arm adduction. Tests AC joint.
- Lift-off test: Strength in lifting dorsum of hand off back. Tests subscapularis.
- Impingement test: Pain w/ passive internal rotation/forward flexion. Tests subacromial impingement.
26.5.2.1 Common Associations
- Scapular winging i/s/o recent trauma or viral illness → likely serratus anterior or trapezius dysfunction
- Inability to passively/actively rotate affected arm externally s/p seizure → likely posterior shoulder dislocation
- Supraspinatus/infraspinatus wasting → likely rotator cuff tear or suprascapular nerve entrapment
- Decreased cervical ROM w/ pain radiating below elbow → likely cervical disc disease
- Shoulder pain in a throwing athlete w/ anterior glenohumeral joint pain/impingement → likely glenohumeral joint instability
- Pain or “clunking” sound w/ overhead motion → likely labral disorder
26.5.3 Proximal Humeral Fracture

History of trauma, severe shoulder pain, pain w/ arm movement
26.5.3.3 Diagnosis

- Blow to abducted/externally rotated/extended arm
- FOOSH
- Forceful forward swinging of arm
26.5.4.2 Diagnosis
- Exam: Arm abducted and externally rotated w/ resistance to all movement, loss of rounded appearance of shoulder. Evaluate for sensory loss over lateral deltoid (2/2 axillary nerve dysfunction).
- Imaging: AP + scapular “Y” + axillary XR to confirm dx and exclude fractures (can be repeated post-reduction if unsure of success)
26.5.4.3 Management
Reduction (variety of techniques exist) → immobilization and referral to Sports Med/Ortho for prevention of recurrent dislocation

- Imaging: XR (abnormal in more severe injury, may be normal if joint space not widened)
26.5.7.3 Management

- Any sign of neurovascular compromise → acute reduction needed
26.6 Lower Extremity: Hip
26.6.1 Anatomy
26.6.2 Exam Pearls & Special Tests
- Hip pain can refer to groin, thigh, or knee, or can present as limp/refusal to walk w/o complaint of pain
- Pain from intra-articular pathology often localizes to groin
- Barlow/Ortolani: Remember to apply gentle anterior pressure to the trochanter during abduction (Ortolani test)
- Trendelenburg test: Positive when patient stands on one leg and the contralateral hip drops, indicative of gluteals/hip abductor weakness
- FABER (Flexion, Abduction, External Rotation): Test for hip or SI joint pathology
- FADIR (Flexion, Adduction, Internal Rotation): Test for hip impingement
- Log roll test: Patient on back w/ leg fully extended and relaxed, examiner passively rotates leg and hip internally and externally. Pain should yield high suspicion for intra-articular pathology.
