Insights
Percutaneous retrocapital osteotomy effectively treats hallux valgus long-term. This minimally invasive surgery shows sustained improvements in foot function and alignment after ten years.
Area of Science:
- Orthopedic Surgery
- Foot and Ankle Surgery
- Minimally Invasive Procedures
Background:
- Hallux valgus surgery trends towards percutaneous techniques.
- Long-term superiority of different percutaneous methods remains unclear.
Purpose of the Study:
- Evaluate long-term outcomes of percutaneous distal retrocapital osteotomy of the first metatarsal.
- Analyze a series of patients followed up for ten years.
Main Methods:
- Clinical and radiological evaluation of 115 feet.
- Ten-year follow-up after surgery.
Main Results:
- Significant improvement in AOFAS scale scores (average 42.2 points) at ten years post-surgery.
- Mean hallux angle maintained below 20 degrees.
- Mean intermetatarsal angle of 8.1 degrees.
Conclusions:
- Percutaneous retrocapital metatarsal osteotomy is effective for mild to moderate hallux valgus.
- The procedure offers long-term benefits with minimally invasive advantages.
Purpose:
The current trend in hallux valgus surgery is directed toward percutaneous procedures. However, no evidence that any of these methods of treatment are superior to the others has been described, excepting studies in the long term. The aim of this study was to analyse a series of patients who had undergone a percutaneous distal retrocapital osteotomy of the first metatarsal, and had been followed up for ten years.
Methods:
We carried out a clinical and radiological evaluation of 115 feet ten years after surgery.
Results:
The AOFAS scale results in the tenth postoperative year remained significantly favourable compared to their corresponding values in the preoperative period, yielding an improvement of 42.2 points overall on average. In relation to radiological findings, the mean hallux angle was maintained below 20 °, with a mean intermetatarsal angle of 8.1 °.
Conclusion:
Percutaneous retrocapital metatarsal osteotomy for treatment of mild to moderate hallux valgus is effective in the long term, with the advantages of a minimally invasive procedure.
