Summary
Modular metallic radial head arthroplasty offers an effective alternative to radial head resection for comminuted fractures. This procedure, combined with ligament reconstruction, shows improved clinical outcomes compared to traditional resection methods.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Biomaterials Engineering
Background:
- Historically, radial head resection was the primary treatment for comminuted radial head fractures.
- Outcomes were frequently poor when associated with collateral ligament injuries.
- Modern radial head prostheses offer potential for improved patient results.
Purpose of the Study:
- To evaluate the efficacy of modular metallic radial head arthroplasty for comminuted radial head fractures.
- To compare the outcomes of arthroplasty with ligament reconstruction versus traditional radial head resection.
Main Methods:
- A cohort of 30 patients underwent modular metallic radial head arthroplasty between June 2001 and January 2005.
- Follow-up was available for 28 patients (mean age 49 years) over an average of 29 months.
- Outcomes assessed via pain scales, range of motion, radiographic findings, and grip strength.
Main Results:
- 19 patients achieved excellent or good results based on the Morrey score.
- 8 patients had fair results, and 1 patient had a poor result.
- Radiographic examination revealed periprosthetic osteolysis in 22 patients.
Conclusions:
- Arthroplasty using a modular metallic radial head, coupled with ligament reconstruction, is a viable alternative to radial head resection.
- The EVOLVE prosthesis demonstrated clear clinical advantages over resection in this study.
- This approach may lead to better functional recovery and patient satisfaction.
