Medium-Term Outcomes of Chevron Osteotomy for Hallux Valgus Correction in a Spanish Population: Radiologic and Clinical Parameters and Patient Satisfaction

Abstract

BACKGROUND:Chevron osteotomy for the treatment of mild and moderate hallux valgus obtain good effects. The procedure is suitable for a variety of cases, thereby allowing for a significant degree of correction. This study aimed to investigate Chevron osteotomy procedures for the correction of hallux valgus in the medium-term (2010-2016) by podiatrists surgeons. It takes into account clinical and radiological findings as well as patient perspectives and level of satisfaction.METHODS: All patients were assessed preoperatively, postoperatively and at a final follow-up. Fifty feet (forty five patients). The mean age was 59.43 (range 32 to 80) years. All of the participants signed an informed consent form to take part in the study. The protocols include: chart review, clinical and radiological. Anterior-posterior weight-bearing radiographs were analyzed preoperatively and at final follow-up. All radiological data were assessed by two observers blinded. Clinical and functional measurements as well as evaluation of the satisfaction survey at the final visit were carried out by another researcher blinded to the study. All patients were analyzed with VAS and AOFAS score. It was applied to evaluate clinical effects.RESULTS:Inter and intra-observer reliability was evaluated (ICC- 95%). The average value of the hallux valge angle (HVA) decreased at final follow-up (25.30º {plus minus} 7.21 VS 17.98º{plus minus} 8.18; p=0.041). There was no significant reduction in the average value of the intermetatarsal angle (IMA) at final follow-up (13.13º {plus minus} 3.03 VS 11.3º {plus minus}3.18; p= 0.78). Final AOFAS scale was 83. This study show the relevance of magnet therapy, nail surgery and others additional procedures. No patient was dissatisfied with the aesthetic scarring.CONCLUSIONS: The results showed that radiological results at final follow-up weren´t compatible with relapse of the deformity. The definitive clinical results, and the degree of patient satisfaction achieved with this technique were favorable from the patients' point of view.

The Application of an Allogenic Bone Screw for Stabilization of a Modified Chevron Osteotomy: A Prospective Analysis

“…They are characterized by high patient satisfaction, good functionality, and low complication rates. We were able to reduce the IMA from 12.6 degrees to 4.8 degrees, which corresponds to comparable values in the literature [ 2 , 3 , 5 , 35 , 36 ]. The AOFAS score improved from 51.6 to 90.9 points.…”
