Summary
Short-term immobilization and early exercise are effective for treating posterior elbow dislocations. Most patients regain full function, with rare instances of instability or recurrent dislocation, indicating good intrinsic joint stability.
Area of Science:
- Orthopedic surgery
- Traumatology
- Sports medicine
Background:
- Isolated posterior elbow dislocation is a common injury.
- Assessing the ideal post-reduction treatment is crucial for optimal outcomes.
Purpose of the Study:
- To determine the optimal treatment strategy for isolated posterior elbow dislocations after reduction.
- To evaluate the efficacy of short-term immobilization and early functional exercise.
Main Methods:
- A study of 36 patients with isolated posterior elbow dislocations post-reduction.
- Patients underwent varus/valgus stress and push-draw tests for stability assessment.
- Treatment involved short-term immobilization (3-7 days) with early active motion, tailored by age.
Main Results:
- All patients achieved satisfactory stability post-reduction.
- Most patients (32/36) fully rehabilitated within 3-4 months.
- No recurrent dislocations or significant long-term complications like ectopic calcification were observed.
Conclusions:
- The ulna-humeral joint possesses intrinsic stability, facilitating healing even with early motion.
- Short-term immobilization and early functional exercise are recommended for isolated posterior elbow dislocations.
- Long-term strict immobilization is generally unnecessary, as instability and recurrent dislocations are rare.
