Background
- Typically occur in elderly osteoporotic pts from FOOSH mechanism
- Must rule-out axillary and brachial plexus neurovascular injuries
- Greater tuberosity fx suggests rotator cuff tear
- Lesser tuberosity fx suggests posterior shoulder dislocation
Clinical Features
- Pain, swelling, tenderness about the shoulder
- Arm is held closely against chest wall
Differential Diagnosis
Humerus Fracture Types
Shoulder and Upper Arm Diagnoses
Traumatic/Acute:
- 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
- Axillary artery thrombosis
- Thoracic outlet syndrome
- Subclavian steal syndrome
- Pancoast tumor
- Myocardial infarction
- Pneumonia
- Pulmonary embolism
Diagnosis
- AP, lateral, and axillary radiographs
- Fracture of articular surface suggested by pseudosubluxation:
- Superior joint hematoma pushes humerus down
Neer System
- Proximal humerus is divided into four "parts" based on epiphyseal lines:
- Articular surface of humeral head
- Greater tubercle
- Lesser tubercle
- Shaft of humerus
- A "one-part" fracture is one in which fragment is displaced <1cm or not angulated >45deg
Management
- "One-part" fracture:
- Sling and swathe, ice, ortho referral
- More than one-part fractures:
- Ortho consult in the ED
