(Redirected from Shoulder Dislocation)
Contents
Background
- Humerus separates from the scapula at the glenohumeral joint
- Partial dislocation of the shoulder is referred to as subluxation
Types
Differential Diagnosis
Shoulder and Upper Arm Diagnoses
Traumatic/Acute:
- Shoulder Dislocation
- Clavicle fracture
- Humerus fracture
- Scapula fracture
- Acromioclavicular 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
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
Evaluation
- Plain film X-ray
- Ultrasound

Anterior shoulder dislocation with fracture
Management
- Reduction
- See individual types for specific techniques
- Cochrane review notes lower complications, equal pain control, and shorter ED stay with intra-articular lidocaine vs. procedural sedation
- 20 mL of 1% lidocaine intra-articular injection[1]
Disposition
- Uncomplicated dislocation can be discharged after reduction
- Recurrence rate around 27% if older than 30 years and 72% is younger than 23 years[2]
