The Stoffella surgical method is a reverse Chevron distal metatarsal osteotomy, typically used in younger patients, with good bone quality. The technique is suitable for a variety of cases, from mild to severe, since the head of the first metatarsal may be moved laterally to the edge of the first metatarsal bone, thereby allowing for a significant degree of correction.
The aim of the paper
is to review the radiological results of patients suffering from hallux valgus who underwent Stoffella metatarsal I osteotomy.
Material and methods
. The study has been carried out using a sample of 23 patients, evaluating their pre and post-surgery radiographs. It seeks to examine the effectiveness of the Stoffella metatarsal I osteotomy by measurements of the HVA (Hallux Valgus Angle), IMA (Intermetatarsal Angle), DMAA (Distal Metaphyseal Articular Angle) both prior to and post-surgical correction.
Results
. The study demonstrated that the Stoffella Metatarsal I osteotomy has a high rate of success, with correction of the HVA, IMA, DMAA angles, with pre- surgery HVA being 29.7°±6.1°, IMA – 12.9°±3.6°, DMAA – 13.7°±7.1°, Post-surgery results show a mean reduction of 51.28%, 51.13%, 50.56% respectively towards a mean HVA of 14.5°±7.4° (p<0.001), mean IMA of 6.3°±3.7° (p<0.001), mean DMAA of 6.8°±4° (p<0.001). All patients who underwent the surgery had HVA, IMA, DMAA angles within the normal physiological range post-surgery.
Conclusions
. It was concluded that the Stoffella Metatarsal I osteotomy is effective in the correction of the hallux valgus.
