Resultados de la técnica de Regnauld para el tratamiento del hallux valgus y el hallux rigidus en 147 casos a los 3 años

Abstract

Purpose To assess radiological, clinical and functional results at 3 years’ evolution of patients subjected to surgical correction of hallux valgus and hallux rigidus by means of the Regnauld technique. Materials and Methods Descriptive retrospective study of 131 patients and 147 cases operated through the Regnauld technique between 2003 and 2006. One hundred and one females and 30 males were reviewed; 16 cases were bilateral. Mean age was 70 years. Mean follow-up was 3 years. Additional surgical maneuvers were used in 73 cases. Before and after surgery, an assessment was made of the patients’ clinical and functional status using both the AOFAS and a subjective scale; measurements were taken of the metatarsophalangeal (MTP), intermetatarsal (IM) and distal articular set angles (DASA). Results The degrees of correction achieved were 16.6° for the MTP angle, 2° for the IM angle and 1.7° for the DASA angle. Scores on the AOFAS scale improved from 39.6 to 85.4 points. On the subjective scale, 25% of cases rated their result as excellent, 68% as good and 2% as poor. As far as complications were concerned, there were 4.7% recurrences, 2% instances of moderate pain with no cases of hallux rigidus, hallux varus or infection. There were no reoperations. Conclusions The technique makes it possible to shorten the first phalanx, correct rotations, reduce the MTP and DASA angles, preserve the joint's congruence and integrity los AMTF y DASA and regain its function.
