Hallux Valgus and Bunion Clinical Trial
Official title:
Midterm Results After Minimally Invasive Distal Chevron Osteotomy: Comparison of Our Results to the Minimally Invasive Reverdin-Isham Osteotomy From a Systematic Review of the Literature.
This study analyses the Reverdin Isham procedure, which is the most popular minimally invasive surgical hallux valgus correction method and the minimally invasive chevron osteotomy, representing the standard technique of open surgery. It is hypothesized that the two techniques would show significant differences in regard to radiological outcome (Hypothesis 1), clinical outcome (Hypothesis 2) and development of radiological recurrence (Hypothesis 3).
Multiple different surgical techniques have been established for hallux valgus surgery so
far, each technique with its unique advantages and limitations. The distal chevron method is
widely accepted as a surgical method for correcting mild to moderate hallux valgus
deformities. Numerous publications presenting the radiological outcome of this surgical
technique and the clinical outcome by means of well established score systems have been
published and make this technique, today's benchmark in hallux surgery.
Due to scarring and decreased range of motion of the greater toe joint after open surgery and
increasing patients' demands several minimally invasive techniques have been brought to
public in the last few years. These techniques claim minor soft tissue damage and reduced
surgical time. The efficiency and stability of correction, as well as the clinical outcome of
these techniques have been discussed controversially. However, most studies present data from
minimally invasive surgery without specific differentiation of the type of surgery and in
regard to the clinical and radiological outcome.
Recently a prospective randomized study comparing the open versus the minimally invasive
chevron technique has been published presenting data with comparable clinical and
radiological outcome.
Given the above-mentioned lack of evidence it was the aim of the study to compare the results
of two different minimally invasive techniques. The investigators analyzed the Reverdin Isham
procedure, which is known as the technique, that made minimally invasive hallux surgery
popular and the minimally invasive chevron osteotomy. It was hypothesized that the two
techniques would show significant differences in regard to radiological outcome (Hypothesis
1), clinical outcome (Hypothesis 2) and development of radiological recurrence (Hypothesis
3).
