Study Notes
Elbow Joint Anatomy
- The elbow joint has anterior (front) and posterior (back) structures.
- Anterior structures include the capitulum and trochlea.
- The head of the radius is also an anterior structure.
- Posterior structures include the olecranon and the trochlear notch.
Elbow Joint Stability
- The ulnar/medial collateral ligament prevents valgus instability.
- The radial/lateral collateral ligament prevents varus instability.
- The ulnohumeral articulation provides structure.
- The annular ligament helps position the radius.
Lateral Epicondylitis (Tennis Elbow)
- It is a common overuse injury.
- Repetitive activities like grasping, pulling, and hammering can cause it.
- It affects the wrist extensors.
- 35-50% of tennis players experience this.
- It is more common in patients over 35 years old.
Lateral Epicondylitis (Tennis Elbow) - Pathophysiology
- The primary structure affected is the extensor carpi radialis brevis tendon.
- Tendinitis is an acute inflammatory response increasing tissue healing.
- Tendinosis is a chronic, degenerative condition.
- Tendinopathy encompasses both acute and chronic issues.
Lateral Epicondylitis (Tennis Elbow) - Symptoms
- Pain gradually begins, typically lateral to the elbow.
- Pain worsens with activity.
- Daily activities like holding a coffee cup or gallon of milk can cause pain.
- The pain might radiate into the forearm, hand, and the lateral side of the arm.
- Pain may be present during the night.
Lateral Epicondylitis (Tennis Elbow) - Diagnosis
- Physicians look for localized tenderness.
- Muscle strength assessment, specifically resisted wrist extension, is common.
- Range of motion (ROM) assessment is typically normal.
- The Cozen's test helps evaluate tenderness by applying pressure.
Lateral Epicondylitis (Tennis Elbow) - Chronic Cases
- Shoulder stability and scapular integrity need assessment.
- Scapular stabilizer weakness might lead to the condition.
- Referred pain may originate from the cervical spine (C5-C6).
- Other conditions like glenohumeral joint problems, elbow osteoarthritis, lateral epicondyle avulsion, and lateral ligament sprains can coexist, warranting investigation.
Lateral Epicondylitis (Tennis Elbow) - Treatment (Acute Stage)
- Protect the injured tendon from further stress, avoiding activities that exacerbate pain.
- Reduce pain and inflammation (e.g., ice, ultrasound, iontophoresis, topical NSAIDs).
- Maintain or improve range of motion.
- Use splints during activities to maintain extensor muscle rest.
- Proper positioning will aid in reducing maximum muscular contraction.
Lateral Epicondylitis (Tennis Elbow) - Treatment (Continued)
- Counterforce bracing (tennis elbow strap) is used to unload the area of origin at the elbow.
- Further muscle atrophy and negative effects should be avoided with proper bracing and exercises.
- Transverse friction massages are beneficial for releasing underlying adhesions.
- Exercises like range of motion to improve circulation and collagen orientation are helpful.
- Include gentle stretches along with progressive exercises for complete recovery.
Lateral Epicondylitis (Tennis Elbow) - Treatment (Continued)
- Focus on progressive eccentric exercises to improve forearm muscles, particularly wrist extensors.
- Proper positioning of the elbow (ext), forearm (pronated), and wrist (ext) position are important for these exercises.
Scapular Stabilization Exercises
- These are crucial for overall shoulder health (related to previous subheadings).
Rotator Cuff Strengthening Exercises
- These are crucial for rotator cuff health (related to previous subheadings).
Chronic Stage Treatment
- Includes ultrasound, deep friction massage, and stretching/strengthening.
- Scapular stabilization and sports-specific training are vital here.
Return to Play
- Athletes can return to play once full strength, and complete ROM are reached.
- A brace may be needed for temporary support.
- Athletes should continue with therapy during recovery.
Medial Epicondylitis (Golfer's Elbow)
- Often involves the common flexor tendons (e.g., flexor carpi radialis).
- Results in repetitive microtrauma due to valgus stress.
- Less frequent than lateral epicondylitis (<10%).
Medial Epicondylitis (Golfer's Elbow) - Risk Factors
- Training errors.
- Repeated wrist flexion and forearm pronation.
- Biomechanical abnormalities (e.g., poor strength, flexibility imbalance).
Medial Epicondylitis (Golfer's Elbow) - Special Test
- Golfer's elbow test (reverse Cozen's test).
Medial Epicondylitis (Golfer's Elbow) - Treatment
- Treatment mirrors lateral epicondylitis, but focuses on stretching and strengthening wrist flexor muscles.
Cubital Tunnel Syndrome
- Ulnar nerve entrapment in the cubital tunnel.
- Symptoms include numbness, tingling, in the elbow.
- Commonly involves the fifth digit.
- Symptoms worsen with elbow flexion activities.
- Night symptoms of numbness and tingling are frequent.
- Loss of grip strength, claw deformity, and weak hand are possible.
Cubital Tunnel Syndrome - Special Tests
- Tinel's sign.
- Elbow flexion test.
Cubital Tunnel Syndrome - Conservative Treatment
- Patient instruction, behavior modification, anti-inflammatory medications, night splints, elbow supports.
- Avoiding aggravating activities, rest, physical therapy, ultrasound, and corticosteroid injections can aid in recovery.
Return to Play (Cubital Tunnel Syndrome)
- Play resumption depends on therapy and recovery time.
- Athletes should have pain-free complete ROM.
- Any continued therapy needs to be focused on safe movements to prevent recurrence.
