Summary
Diagnosing posterior shoulder dislocation and fracture-dislocation is often missed. Early diagnosis with axillary X-rays is crucial for better outcomes, despite initial good results from late treatment.
Area of Science:
- Orthopedic Surgery
- Radiology
Background:
- Posterior shoulder dislocations and fracture-dislocations are uncommon injuries.
- Diagnosis can be challenging, leading to delayed treatment.
Observation:
- This report details six cases: two posterior dislocations (PD) and four posterior fracture-dislocations (PFD).
- Some cases involved bilateral injuries.
- Treatments ranged from closed reduction for PD to operative reduction for PFD.
Findings:
- Late treatment (1-10 months post-injury) yielded good initial results.
- However, long-term outcomes were poor due to post-traumatic arthrosis.
- The average follow-up was 4 years.
Implications:
- Axillary X-rays are essential for diagnosing posterior shoulder dislocations.
- Timely and accurate diagnosis is critical to prevent long-term complications like arthrosis.
