Summary
Posterolateral rotatory instability (PLRI) is a common elbow pathology resulting from ligamentous injury, often due to trauma. Improved diagnostic tools and arthroscopic surgery offer better treatment options for elbow instability.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Elbow Pathology
Background:
- Posterolateral rotatory instability (PLRI) is increasingly recognized as a significant cause of elbow pathology.
- PLRI stems from insufficiency of the radial ulnohumeral ligament and associated lateral structures, typically following elbow trauma.
Purpose of the Study:
- To review the current understanding of PLRI, including its diagnosis and treatment.
- To highlight advancements in diagnostic methods and surgical interventions for elbow instability.
Main Methods:
- Literature review of PLRI, focusing on diagnostic advancements and treatment evolution.
- Analysis of diagnostic tools like the PLRI test and MR imaging.
- Comparison of open reconstruction versus arthroscopic techniques for elbow stabilization.
Main Results:
- The PLRI test and advanced MR imaging have improved diagnostic accuracy for elbow instability.
- Arthroscopic techniques are emerging as a satisfactory alternative to traditional open reconstruction for stabilizing the elbow.
Conclusions:
- PLRI is a significant elbow condition with improved diagnostic capabilities.
- Advancements in arthroscopic surgery offer effective alternatives for treating elbow instability caused by PLRI.
