Evaluating and Treating Sports Injuries in Young Athletes
EVALUATING & TREATING SPORTS INJURIES IN YOUNG ATHLETES: SHOULDER, ELBOW, HAND & WRIST Rachel A. Coel, MD, PhD Co-Medical Director Sports Medicine for Young Athletes Children’s Hospital Colorado DISCLOSURES No financial conflicts or disclosures today I Grew Up in Hawaii… …and graduated from Punahou School like President Obama. OBJECTIVES • Describe techniques for diagnosing upper • • extremity injuries in youth. Describe common treatment options for upper extremity injuries. Recognize need for appropriate referral to orthopedic specialist. INTENSITY INTENSITY INTENSITY “DiME” Pediatric Bone vs. Adult • Higher H20 content, lower mineral content per unit • • • volume. More elastic and higher strain : failure ratio Growth plate – usually weaker than bone and prone to injury in and around it. Also very vascular which hastens repair. (Salter Harris fx’s) Thick periosteum adds protection to bone like bark on a green tree limb, also hastens healing. (Torus fx, plastic deformity/greenstick fx, spiral fx) • Ligaments stronger than bone – mechanism producing sprain in adult will typically cause fracture in child Physeal (Growth Plate) Fractures - General • “Weak link” of pediatric bone (cartilage) • Adults - sprains & dislocations; children • • • • physeal injuries Rapid healing (1/2 time of shaft fractures) Tenderness over physis: suspect a SH I fracture, even with normal radiographs! Risk of premature growth arrest leading to limb length discrepancy or angular deformity Risk of articular complications (SH type 3-5) Examples Chronic Injury • Joint overload • ie: Patellofemoral • • • • • Stress Fracture Apophysitis (ie: Sever’s) Epiphysitis (ie: Little Leaguer’s elbow) Tendonitis Burnout / Overtraining Physical Exam • Inspection • Palpation (bony • • • • structures, joints, soft tissue) Active & passive ROM Strength testing Neurovascular Special tests Musculoskeletal Physical Exam 1) Inspection: swelling, bruising, angulation, 2) 3) 4) 5) 6) deformity, shortening, or rotation Gentle Palpation: with focus on bony vs. soft tissue structures; crepitus; step-off’s; bony mass; growth plates ($1,000,000 exam tool: one finger to localize tenderness) ROM: flexion, extension, abduction, adduction, Neurovascular: motor function, vascular function, strength, and sensory perception Special maneuvers: ligaments, tendons, laxity Beware of bony tenderness in the absence of any trauma history! BASIC PRINCIPLES: “PRICEMM” P = Protect R = Rest I = Ice C = Compression E = Elevation M = Medications M = Modalities BE SURE TO ALWAYS CHECK NEUROVASCULAR STATUS! •Pulse •Capillary refill •Warmth & Color •Sensation •Motor function •Strength SHOULDER 12 year old female swimmer • Right shoulder pain x 1 month • No known injury or trauma • Radiates to upper arm, shoulder blade Causes of Shoulder Pain in Pediatrics • Injuries - AC joint sprain, Clavicle fx, Humerus fx • Shoulder instability / Multi-Directional Instability (MDI) - Subluxation - Dislocation • Rotator Cuff Syndrome, Impingement Syndrome - Overhead athletes • Little League Shoulder • Tumor Could it be a fracture? Little Leaguer’s Shoulder Abnormal Normal Little Leaguer’s Shoulder Proximal Humeral Epiphysitis • Stress fracture: proximal humeral physis • High level pitchers 11-16 yrs of age • Exam may be normal • X-ray may be negative early • Looks like growth plate fx • Check comparison xray Little Leaguer’s Shoulder Treatment • • • • • NO THROWING x 3-6 mo P.T. – Throwing program / Biomechanics SLOW return, consider switching position Pitch counts Choose pitcher or catcher Little Leaguer’s Shoulder HUMERUS FRACTURES - PROXIMAL - SHAFT •REFER to Ortho •Arm sling x 6 weeks •RTP at 10-12 weeks •REFER to Ortho •Sling x 4 weeks •RTP at 6-8 weeks 8 weeks CLAVICLE FRACTURE An Example of Pediatric Healing Potential Does she have a rotator cuff injury? Rotator Cuff Tendinitis / Tear • Partial thickness tear • Full (Complete) thickness tear • May be due to: • • • • Impingement Degeneration Overuse Trauma • Partial tears • Conservative • Complete tears • Surgery • Supraspinatus - Abduction • “Empty can" test • a.k.a. Jobe’s Test • Arms abducted 90° and • Arms at 30° (in scapular plane) • Elbows locked straight • Thumbs down • Attempts to elevate arms against resistance • Infraspinatus, Teres Minor • Externally rotates shoulder • Arms at the sides - Elbows flexed to 90 degrees • Externally rotates arms against resistance • Subscapularis - Internally rotates shoulder - Arms at the sides - Elbows flexed to 90° - Internally rotate arms against resistance - Subscapularis Lift-Off Test Does she have impingement? Impingement Signs Neer’s Sign – Arm fully pronated and placed in forced flexion – Trying to impinge subacromial structures with humeral head – Pain is positive test Impingement Signs Hawkin’s Sign – Arm is forward flexed to 90°, then forcibly internally rotated – Trying to impinge subacromial structures with humeral head – Pain is positive test Biceps Tendinitis: Speed’s Test • Shoulder forward flexed to 90° • Arm in full supination • Apply downward force to distal arm • Pain is positive test • Weakness without pain: muscle weakness or rupture Shoulder Instability / MDI Failure to keep humeral head centered in glenoid Dislocation – Complete disruption of joint congruity or alignment Subluxation – Partial or incomplete dislocation Laxity – Looseness in joint – May be normal or abnormal •Dislocation: REFER for Xrays, MRI, sling x 2 weeks, P.T., – MANAGE with P.T., activity modification Instability / MDI: Sulcus Sign • Inferior instability • Arm relaxed in neutral position • Arm pulled downward • Positive test is a visible sulcus at infra-acromial area • Compare to contralateral side Instability: Apprehension Test • Anterior instability • Shoulder abducted 90°, externally rotated • Stress to humeral head directed in anterior direction • Positive test is apprehension due to feeling of instability or impending dislocation Instability: Relocation Test • Anterior instability • After a positive apprehension, apply posteriorly directed force over externally rotated humeral head • Positive test is relief of apprehension Shoulder Dislocation: Check over deltoid Does she have an AC joint sprain? Acromio-clavicular (AC) Joint Sprain – Typically due to fall onto tip of shoulder (acromion) – Arm tucked into side – Treatment depends on type – MANAGE Types 1 & 2 – Sling, P.T. – REFER Types 3-6 AC Joint: Cross-Arm Adduction Test • Arm forward flexed to 90° and adducted 45° • Hyperadduct shoulder • Resist abduction of elbow • Positive test is pain in AC joint Could she have any joint damage? Glenoid Labral Tear Usually due to instability Acute vs. Chronic – Fall on outstretched hand or shoulder – Rotator cuff tendinosis or tears – Anterior shoulder dislocation / subluxation – REFER to Ortho O’Brien’s Active Compression Test • Labral, AC, or biceps pathology • Arm forward flexed 90° and adducted ~15° • Resist downward force with hand fully pronated • Positive test if pain • Beware location of pain • AC • Biceps • Internal +/- click Elbow 13 year old male “righty” baseball pitcher • Right elbow pain x 2 days • Sudden onset without a “pop” • 6 hours later: swelling • Plays on two teams (club & school) • Plays year-round • Alternate position: catcher Pediatric Elbow 1 – Capitellum 2 – Radial head 3 – Medial Epicondyle 4 – Trochlea 5 – Lateral Epicondyle Physical Exam • Inspect • Palpate - Medial structures (medial epicondyle, flexor/pronators) - Lateral structures (lateral epicondyle, radiocapitellar joint, extensor muscles) - Posterior structures (olecranon process, bursa) Range of Motion Elbow stability (varus / valgus stress) Strength testing NERVE TESTING • Dorsiflex wrist: Radial nerve weakness • Abduct ulnar half of fingers: Ulnar nerve weakness • Appose thumb and index finger tips (O sign): Median nerve weakness Loss of full range of motion… **Must MRI** Medial Epicondyle Apophysitis: “Little League Elbow” • Traction apophysitis of • • • • medial epicondyle Etiology: repetitive overuse Valgus overload Typical age: 10-15 yrs Medial elbow pain worse with throwing activity Little Leaguer’s Elbow Abnormal Normal Little League Elbow • Exam - tenderness over medial epicondyle - pain with resisted flexion and pronation, valgus stress • MANAGE with Rest, Ice, P.T. (interval throwing program), pitch counts/types If there was trauma and the elbow is swollen, do NOT push on it or passively test range of motion. * THINK “FRACTURE” * Elbow: Supracondylar Fractures • Most common elbow fx; 10% of pediatric fx’s • Mechanism = FOOSA • Can be occult: suspect if + fat pad, or • • • displacement of AH line Cannot tolerate > 5 degrees angulation (can result in a varus “gunstock” deformity) Tx if not displaced or angulated: posterior 90o splint or long arm cast for 3-6 weeks 1 week follow-up Type I and Type II SC Fx’s Type III SC Fx Flexion-type SC Fx PATHOLOGIC FAT PADS Anterior Humeral Line Radiocapitellar Line ELBOW FRACTURE • Posterior long arm splint WRIST 14 year old male swimmer Slipped on pool deck.
