functional anatomy
Functional Anatomy
  • Complex that allows for flexion, extension, pronation and supination
    • 145 degrees of flexion and 90 degrees of supination and pronation
  • Bony limitations, ligamentous support and muscular stability at the elbow help to protect it from overuse and traumatic injuries
  • Elbow demonstrates a carrying angle due to distal projection of humerus
    • Normal in females is 10-15 degrees, males 5 degrees
  • Critical link in kinetic chain of upper extremity
assessment of the elbow

Special Tests
    • Circulatory and Neurological Function
      • Pulse should be taken at brachial artery and radial artery
      • Skin sensation should be checked - determine presence of nerve root compression or irritation in cervical or shoulder region
      • Tinel’s sign
        • Ulnar nerve test
        • Tap on ulnar nerve (in ulnar groove)
        • Positive test is found when athlete complains of sensation along the forearm and hand
    • Test for Capsular Injury
      • Tested after hyperextension of elbow
        • Elbow is flexed to 45 degrees, wrist is fully flexed and extended
        • If joint pain is severe, moderate/severe sprain or fracture should be suspected
slide12
Valgus/Varus Stress Test
    • Assess injury to the medial and lateral collateral ligaments, respectively
    • Looking for gapping or complaint of pain
slide13
Medial and Lateral Epicondylitis Tests
    • Elbow flexed to 45 degrees and wrist extension or flexion is resisted
    • Pain at lateral or medial epicondyle, respectively indicates a positive test
  • Pinch Grip Test
    • Pinch thumb and index finger together
    • Inability to touch fingers together indicates entrapment of anterior interosseous nerve between heads of pronator muscle
  • Pronator Teres Syndrome Test
    • Forearm pronation is resisted
    • Increased pain proximally over pronator teres indicates a positive test
functional evaluation
Functional Evaluation
  • Pain and weakness are evaluated through AROM, PROM and RROM
    • Flexion, extension, pronation and supination
    • ROM of pronation and supination are particularly noted
recognition and management of injuries to the elbow
Recognition and Management of Injuries to the Elbow
  • Subject to injury due to broad range of motion, weak lateral bone structure, and relative exposure to soft tissue damage
  • Many sports place excessive stress on joint
  • Locking motion of some activities, use of implements, and involvement in throwing motion make elbow extremely susceptible
slide16
Contusion
    • Etiology
      • Vulnerable area due to lack of padding
      • Result of direct blow or repetitive blows
    • Signs and Symptoms
      • Swelling (rapidly after irritation of bursa or synovial membrane)
    • Management
      • Treat w/ RICE immediately for at least 24 hours
      • If severe, refer for X-ray to determine presence of fracture
slide17
Olecranon Bursitis
    • Etiology
      • Superficial location makes it extremely susceptible to injury (acute or chronic) --direct blow
    • Signs and Symptoms
      • Pain, swelling, and point tenderness
      • Swelling will appear almost spontaneously and w/out usual pain and heat
    • Management
      • In acute conditions, compression for at least 1 hour
      • Chronic cases require superficial therapy primarily involving compression
      • If swelling fails to resolve, aspiration may be necessary
      • Can be padded in order to return to competition
slide18
Strains
    • Etiology
      • MOI is excessive resistive motion (falling on outstretched arm), repeated microtears that cause chronic injury
      • Rupture of distal biceps is most common muscle rupture of the upper extremity
    • Signs and Symptoms
      • Active or resistive motion produces pain; point tenderness in muscle, tendon, or lower part of muscle belly
    • Management
      • RICE and sling in severe cases
      • Follow-up w/ cryotherapy, ultrasound and exercise
      • If severe loss of function encountered - should be referred for X-ray (rule out avulsion or epiphyseal fx
slide19
Ulnar Collateral Ligament Injuries
    • Etiology
      • Injured as the result of a valgus force from repetitive trauma
      • Can also result in ulnar nerve inflammation, or wrist flexor tendinitis; overuse flexor/pronator strain, ligamentous sprains; elbow flexion contractures or increased instability
    • Signs and Symptoms
      • Pain along medial aspect of elbow; tenderness over MCL
      • Associated paresthesia, positive Tinel’s sign
      • Pain w/ valgus stress test at 20 degrees; possible end-point laxity
      • X-ray may show hypertrophy of humeral condyle, posteromedial aspect of olecranon, marginal osteophytes; calcification w/in MCL; loose bodies in posterior compartment
slide20
Ulnar Collateral Ligament Injuries (cont.)
    • Management
      • Conservative treatment begins w/ RICE and NSAID’s
      • W/ resolution, strengthening should be performed; analysis of the throwing motion (if applicable)
      • Surgical intervention may be necessary (Tommy John procedure)
        • Throwing athlete can return to activity 22-26 weeks post surgery
slide21
Lateral Epicondylitis (Tennis Elbow)
    • Etiology
      • Repetitive microtrauma to insertion of extensor muscles of lateral epicondyle
    • Signs and Symptoms
      • Aching pain in region of lateral epicondyle after activity
      • Pain worsens and weakness in wrist and hand develop
      • Elbow has decreased ROM; pain w/ resistive wrist extension
slide22
Lateral Epicondylitis (continued)
    • Management
      • RICE, NSAID’s and analgesics
      • ROM exercises and PRE, deep friction massage, hand grasping while in supination, avoidance of pronation motions
      • Mobilization and stretching in pain free ranges
      • Use of a counter force or neoprene sleeve
      • Mechanics training
slide23
Medial Epicondylitis
    • Etiology
      • Repeated forceful flexion of wrist and extreme valgus torque of elbow
    • Signs and Symptoms
      • Pain produced w/ forceful flexion or extension
      • Point tenderness and mild swelling
      • Passive movement of wrist seldom elicits pain, but active movement does
    • Management
      • Sling, rest, cryotherapy or heat through ultrasound
      • Analgesic and NSAID's
      • Curvilinear brace below elbow to reduce elbow stressing
      • Severe cases may require splinting and complete rest for 7-10 days
slide24
Elbow Osteochondritis Dissecans
    • Etiology
      • Impairment of blood supply to anterior surface resulting in degeneration of articular cartilage, creating loose bodies
      • Repetitive microtrauma in movements of elbow rotation, extension, valgus stress causing compression of the radial head ad shearing of the radiocapitular joint
      • Seen in young athletes involved in throwing motion
      • Panner’s disease in incidents of children age <10
    • Signs and Symptoms
      • Sudden pain, locking; range usually returns in a few days
slide25
Signs and Symptoms (continued)
    • Swelling, pain at radiohumeral joint, creptitus, decreased ROM (full extension); grating w/ pronation and supination
    • X-ray may show flattening and crater of capitulum w/ loose bodies
  • Management
    • Activity restriction for 6-12 weeks; NSAID’s
    • Splint and cast applied for cases of extensive deterioration
    • If repeated locking occurs, loose bodies are removed surgically
slide26
Little League Elbow
    • Etiology
      • Caused by repetitive microtraumas that occur from throwing (not type of pitch)
      • May result in numerous disorders of growth in the pitching elbow
    • Signs and Symptoms
      • Onset is slow; slight flexion contracture, including tight anterior joint capsule and weakness in triceps
      • Athlete may complain of locking or catching sensation
      • Decreased ROM or forearm pronation and supination
slide27
Little League Elbow (continued)
    • Management
      • RICE, NSAID’s and analgesics
      • Throwing stops until pain resolved and full ROM is regained
      • Gentle stretching and triceps strengthening
      • Throwing under supervision w/ good technique to prevent recurrence
slide28
Cubital Tunnel Syndrome
    • Etiology
      • Pronounced cubital valgus may cause deep friction problem
      • Ulnar nerve dislocation
      • Traction injury from valgus force, irregularities w/ tunnel, subluxation of ulnar nerve due to lax impingement, or progressive compression of ligament on the nerve
    • Signs and Symptoms
      • Pain medially which may be referred proximally or distally
      • Tenderness in cubital tunnel on palpation and hyperflexion
      • Intermittent paresthesia in 4th and 5th fingers
slide29
Cubital Tunnel Syndrome (continued)
    • Management
      • Rest, immobilization for 2 weeks w/ NSAID’s
      • Splinting or surgical decompression or transposition of subluxating nerve may be necessary
      • Athlete must avoid hyperflexion and valgus stresses
slide30
Dislocation of the Elbow
    • Etiology
      • High incidence in sports caused by fall on outstretched hand w/ elbow extended or severe twist while flexed
      • Bones can be displaced backward, forward, or laterally
      • Distinguishable from fracture because lateral and medial epicondyles are normally aligned w/ shaft of humerus
    • Signs and Symptoms
      • Swelling, severe pain, disability
      • Complications w/ median and radial nerves and blood vessels
      • Often a radial head fracture is involved
slide31
Management
    • Cold and pressure immediately w/ sling
    • Refer for reduction
    • Neurological and vascular fxn must be assessed prior to and following reduction
    • Physician should reduce - immediately
    • Immobilization following reduction in flexion for 3 weeks
    • Hand grip and shoulder exercises should be used while immobilized
    • Following initial healing, heat and passive exercise can be used to regain full ROM
    • Massage and joint movement that are too strenuous should be avoided before complete healing due to high probability of myositis ossificans
    • ROM and strengthening should be performed and initiated by athlete (forced stretching should be avoided
slide33
Fractures of the Elbow
    • Etiology
      • Fall on flexed elbow or from a direct blow
      • Fracture can occur in any one or more of the bones
      • Fall on outstretched hand often fractures humerus above condyles or between condyles
        • Condylar fracture may result in gunstock deformity
      • Direct blow to ulna or radius may cause radial head fracture as well
    • Signs and Symptoms
      • May not result in visual deformity
      • Hemorrhaging, swelling, muscle spasm
slide34
Elbow Fractures (continued)
    • Management
      • Decrease ROM, neurovascular status must be monitored
      • Surgery is used to stabilize adult unstable fracture, followed by early ROM exercises
      • Stable fractures do not require surgery
        • Removable splints are used for 6-8 weeks
slide35
Volkmann’s Contracture
    • Etiology
      • Associate w/ humeral supracondylar fractures, causing muscle spasm, swelling, or bone pressure on brachial artery, inhibiting circulation to forearm
      • Can become permanent
    • Signs and Symptoms
      • Pain in forearm - increased w/ passive extension of fingers
      • Pain is followed by cessation of brachial and radial pulses, coldness in arm
      • Decreased motion
    • Management
      • Remove elastic wraps or casts
      • Close monitoring must occur
rehabilitation of the elbow
Rehabilitation of the Elbow
  • General Body Conditioning
    • Must maintain pre-injury fitness levels - cardiovascular and strength (lower body)
  • Flexibility
    • Restoring ROM is critical in elbow rehab
    • Variety of approaches can be used as long as they don’t force the joint
  • Joint Mobilizations
    • Loss of proper arthrokinematics following immobilization is expected
    • Joint mobilization and traction can be very useful to increase mobility and decrease pain through restoration of accessory motions
slide37
Strengthening
    • Achieved through low-resistance, high-repetition exercises - must be pain free
    • Shoulder and grip exercises should also be performed
    • Continuous passive motion units followed by dynamic splinting is ideal following surgery
    • Isometrics can be used while elbow is immobilized
    • PNF and isokinetics are useful in early and intermediate active stages of rehab
    • A graded PRE program w/ tubing, weights or manual resistance should be included
    • Closed kinetic chain activities should also be incorporated - assist in both static and dynamic stability to the elbow
    • Proprioceptive training should also incorporated
slide38
Functional Progressions
    • Will enhance healing and performance
      • PNF, swimming, pulley machines and rubber tubing
      • to simulate sports activities
    • Should include steps
      • Warm-up
      • Gradual build up to activity, becoming increasingly more difficult
  • Return to Activity
    • Can re-engage in activity when criteria has successfully been completed
    • ROM w/in normal limits, strength should be equal w/ no complaint of pain
    • Return should progress with use of restrictions in an effort to objectively measure activity progression
slide39
Protective Taping and Bracing
    • Should be continued until full strength and flexibility have been restored
    • Chronic conditions usually cause gradual debilitation of surrounding soft tissue
      • Must restore maximum state of conditioning w/out encouraging post-injury aggravation
