NO DRUG THERAPY IN PRIMARY CARE (REFERRAL & ADVICE)
Glenohumeral dislocation is common trauma, typically anterior, from a fall or sports injury; needs reduction (often in an emergency setting), post-reduction imaging, and follow-up for recurrent instability. - Refer, with advice
Children follow the same pathway: recognise and refer. No primary-care medicine is implied.

Glenohumeral dislocation is common trauma, typically anterior, from a fall or sports injury; needs reduction (often in an emergency setting), post-reduction imaging, and follow-up for recurrent instability.
- Axillary nerve injury (loss of deltoid sensation), vascular compromise of the arm, recurrent or irreducible dislocation.
- No medicine is prescribed for this in primary care - this entry is for recognition and referral. Anything given is decided by the service it is referred to.
- RED FLAG - A thorough neurovascular exam (axillary nerve - sentinel patch sensation and deltoid firing; axillary artery - distal pulses/perfusion) must be performed and documented before any reduction attempt, since axillary nerve injury occurs in about 42% of acute anterior dislocations and arterial injury, though rare, carries high morbidity if missed.
- RED FLAG - Reduction should not be delayed beyond 24 hours - delay raises the risk of unstable reduction, muscle spasm, and neurovascular compromise.
- RED FLAG - Suspected proximal humerus fracture-dislocation (e.g. marked ecchymosis, completely displaced humeral head) needs emergent orthopedic surgery consultation, since closed reduction is often unsuccessful and urgent open reduction may be required.
- A shoulder dislocation that follows a seizure or an electric shock is likely to be posterior, and posterior dislocations are commonly missed at first presentation.
- An isolated lesser tuberosity fracture on X-ray should prompt a search for an underlying posterior shoulder dislocation.
- A patient holding the arm fixed in a hyper-abducted, overhead position has an inferior dislocation (luxatio erecta), which carries a high rate of neurovascular injury.
- The direction of the dislocation must be confirmed radiographically before any reduction attempt.
- The Hippocratic technique, placing a foot in the axilla as counter-traction, is no longer favoured because it risks causing brachial plexus and vascular injury.
- After a successful reduction, repeat the neurovascular examination, confirm the position on radiographs, and immobilise the arm in a sling.
- Acromioclavicular joint separation can be mistaken for a shoulder dislocation.
- In a patient over 40 with recurrent instability, a rotator cuff tear is the more likely underlying cause.
- A patient under 25 who plays contact sport should be counselled that the risk of the shoulder dislocating again is very high.
