Summary
A novel posterolateral approach for tibiotalar joint injection offers a safe alternative, particularly for severe anterior arthrosis. This technique provides a stable ankle position during injection, enhancing therapeutic outcomes.
Area of Science:
- Orthopedic Surgery
- Radiology
- Anatomy
Background:
- Tibiotalar joint injections are common for ankle pain.
- Anterior approaches can be challenging with severe arthrosis.
- A need exists for alternative injection techniques.
Purpose of the Study:
- To describe a novel posterolateral approach for tibiotalar joint injection.
- To detail the indications and technical considerations for this technique.
- To evaluate the safety and efficacy of the posterolateral approach.
Main Methods:
- The technique mirrors posterior subtalar joint injections.
- Needle insertion is anterosuperiorly beneath the fibula.
- A retrospective review of 12 injections in 8 patients was performed under fluoroscopic guidance.
Main Results:
- All 12 injections were technically successful.
- Patients had anterior predominant arthrosis with osteophytes and joint space narrowing.
- No complications were observed, and injections were well tolerated.
Conclusions:
- The posterolateral approach is a viable alternative to anterior tibiotalar injections.
- It is particularly useful for severe anterior arthrosis.
- The technique offers an advantage of maintaining ankle position during injection.
