Humerus fracture (peds)

This page is for pediatric patients. For adult patients, see: Humerus fracture.

Background

Humerus Fracture Types

Humeral anatomy

• Adult
  • Proximal
  • Shaft
  • Distal
    • Capitellum
    • Trochlea
    • Condylar
• Pediatric
  • Proximal
  • Shaft
  • Distal
    • Supracondylar
    • Lateral epicondyle
    • Medial epicondyle

Comminuted midshaft humeral fracture with callous formation

Differential Diagnosis

Shoulder and Upper Arm Diagnoses

Traumatic/Acute:

• Shoulder Dislocation
  • Anterior shoulder dislocation
  • Posterior shoulder dislocation
  • Inferior shoulder dislocation
• Clavicle fracture
• Humerus fracture
• Scapula fracture
• Acromioclavicular joint injury
• Glenohumeral instability
• Rotator cuff tear
• Biceps tendon rupture
• Triceps tendon rupture
• Septic joint

Nontraumatic/Chronic:

• Rotator cuff tear
• Impingement syndrome
• Calcific tendinitis
• Adhesive capsulitis
• Biceps tendinitis
• Subacromial bursitis
• Cervical radiculopathy

Refered pain & non-orthopedic causes:

• Referred pain from
  • Neck
  • Diaphragm (e.g. gallbladder disease)
• Brachial plexus injury
  • Rucksack paralysis
• Axillary artery thrombosis
• Thoracic outlet syndrome
• Subclavian steal syndrome
• Pancoast tumor
• Myocardial infarction
• Pneumonia
• Pulmonary embolism

Management & Disposition

General Fracture Management

• Acute pain management
• Open fractures require immediate IV antibiotics and urgent surgical washout
• Neurovascular compromise from fracture requires emergent reduction and/or orthopedic intervention
• Consider risk for compartment syndrome

Pediatric Humerus Fracture Management Table

Fracture	Splint	Disposition
Proximal	Sling and swathe splint, or coaptation splint	Non-emergent Ortho follow up
Shaft	Long arm posterior splint, sling and swathe splint, or coaptation splint	Non-emergent Ortho f/u
Supracondylar	Long Arm Posterior Splint	Ortho consult for Type 2 or 3
