[Subnormal functional activity in a neglected posterior dislocation of the shoulder]

|November 26, 1998
Summary
Posterior shoulder dislocation is rare and often missed due to subtle signs. This case highlights a traumatic posterior shoulder dislocation that went unnoticed for 7 weeks, leading to a non-treatment decision.
Area of Science:
- Orthopedics
- Radiology
- Traumatology
Background:
- Posterior shoulder dislocation accounts for 2-5% of glenohumeral dislocations.
- Common causes include trauma, seizures, and electrocution.
- This injury is often misdiagnosed due to subtle clinical signs and normal initial X-rays.
Observation:
- A case of traumatic posterior shoulder dislocation is presented.
- The dislocation remained undiagnosed for seven weeks.
- The patient exhibited satisfactory functional adaptation and was in good general condition.
Findings:
- Delayed diagnosis of posterior shoulder dislocation is possible.
- Clinical examination and axillary radiographs are crucial for diagnosis.
- Non-operative management may be considered in select cases with good functional outcomes.
Implications:
- Highlights the diagnostic challenges of posterior shoulder dislocations.
- Emphasizes the importance of thorough clinical evaluation and appropriate imaging.
- Suggests that non-operative management can be a viable option for chronic, asymptomatic posterior shoulder dislocations.
