Summary
Posterolateral rotatory instability, a common elbow issue, can be treated with a new minimally-invasive lateral ulnar collateral ligament reconstruction. This technique uses a tendon graft and knotless anchors, preserving joint structures for better outcomes.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Elbow Biomechanics
Background:
- Posterolateral rotatory instability is the most frequent type of elbow instability.
- It often results from valgus, supination, and axial loading during elbow extension.
- The lateral ulnar collateral ligament (LUCL) is crucial for preventing this instability.
Purpose of the Study:
- To describe a novel, minimally-invasive technique for lateral ulnar collateral ligament (LUCL) reconstruction.
- To utilize a tendon graft with knotless suture anchors in an onlay fashion.
- To avoid disruption of the articular capsule and common extensor origin during the procedure.
Main Methods:
- A minimally-invasive surgical approach was employed.
- Tendon graft reconstruction of the LUCL was performed.
- Knotless suture anchors were used in an onlay configuration.
- The technique preserved the articular capsule and common extensor origin.
Main Results:
- The described technique offers a minimally-invasive option for LUCL reconstruction.
- The use of knotless anchors and an onlay graft simplifies the procedure.
- Preservation of surrounding structures may lead to improved patient recovery and outcomes.
Conclusions:
- This technical note presents a reproducible, minimally-invasive method for LUCL reconstruction.
- The technique aims to provide a stable elbow by restoring LUCL function.
- Further studies are warranted to evaluate the long-term efficacy and clinical outcomes of this approach.
