“…86-88 The remaining 6 operations are modifications of well-recognized existing HV operative techniques that enable M1 derotation. These operations include modified versions of the: Scarf osteotomy, 79 Chevron osteotomy, 64 Mitchells osteotomy, 51 Lapidus procedure, 13,17,19-21,24,49,69,70,76,77 Bösch osteotomy, 72,73 and the Proximal Crescentic Osteotomy. 60,98 This new class of modifications feature medial wedge excisions, 51,64,79 supination stress realignment, 17,19-21,59,69,70 and unique osteotomy patterns, 60,72,73,98 which give surgeons an enlarged resource of potential techniques to treat HV in the sagittal, transverse, and coronal dimensions.…”

First Metatarsal Rotation in Hallux Valgus Deformity

2021

View full text Add to dashboard Cite

Rotation of the first metatarsal (M1) as a potential etiological factor of hallux valgus (HV) deformity was described relatively early in the description of HV pathoanatomy. However, because biplanar radiographs have been the standard method for imaging HV, clinicians primarily developed measurement methods and corrective operations confined to 2 dimensions, medial-lateral and inferior-superior. Recently, as our understanding of HV pathoanatomy has further developed, aided in part by advanced imaging technology, M1 rotation about its axis (“axial rotation”) and its implications for HV deformity and treatment has reemerged. The goal of this review is to summarize M1 rotation in HV from a historical perspective, to present the current understanding of its potential role in the etiology/pathogenesis of HV, and to summarize relevant imaging and operative considerations with respect to M1 rotation. Level of Evidence: Level III, systematic review.

“…Desde su introducción hace más de 40 años la osteotomía de Chevron ha ganado aceptación en los cirujanos de pie y tobillo como uno de los procedimientos que con más frecuencia se realizan mundialmente para el tratamiento de hallux valgus. 11 Dicha técnica original ha recibido modificaciones, las cuales han permitido mayor nivel de corrección principalmente en el IMA y DMAA. 14 Recientemente Prado y colaboradores describieron la modificación de la osteotomía de Chevron con cuñas de sustracción en la cortical medial, las cuales permiten hacer correcciones en el CR del primer metatarsiano.…”

“…The correlation analysis between the supination correctional angle and the other correctional angles and translations showed that the adduction correction of the distal fragment involved supination correction. To address the rotational deformity in hallux valgus, many surgical techniques have been described, including chevron osteotomy, 42 Lapidus osteotomy, 12 and proximal metatarsal osteotomy. 50 However, contrary to the present findings, no surgeon has recommended adduction correction to supinate the distal fragment.…”

Three-Dimensional Analysis of the First Metatarsal Bone in Minimally Invasive Distal Linear Metatarsal Osteotomy for Hallux Valgus

et al. 2019

Background: Modified Bösch osteotomy (distal linear metatarsal osteotomy [DLMO]) is one of the minimally invasive correctional surgeries for hallux valgus. The 3-dimensional correctional angles and distances of the first metatarsal bone in DLMO have not been clarified. The purpose of this study was to analyze the 3-dimensional postoperative morphological changes of the first metatarsal bone in DLMO. Methods: Twenty patients (30 feet) who underwent DLMO were enrolled. Preoperative plain radiographs and computed tomography (CT) scans of the feet were examined. Postoperative radiographs and CT scans were also obtained after bone union. The surface data of the pre- and postoperative first metatarsals were reconstructed from the CT data. The positions of the distal ends of the first metatarsals described with respect to the proximal ends were calculated using CT surface-matching technique. Results: The distal end of the first metatarsal after DLMO was significantly supinated (10.2 ± 6.0 degrees, P < .001), adducted (6.0 ± 11.8 degrees, P = .004), dorsiflexed (11.1 ± 10.9, P < .001), shortened (7.4 ± 2.5 mm, P < .001), elevated (2.3 ± 3.1 mm, P = .001), and laterally shifted (8.2 ± 3.0 mm, P < .001) compared to the preoperative metatarsal distal end. Supination correction demonstrated a significant correlation with adduction correction ( r = 0.659, P < .001) on correlation analyses between these parameters. Conclusion: The 3-dimensional corrections of the first metatarsal bone after DLMO were evaluated. Pronation and abduction were successfully corrected. Furthermore, adduction correction might be an important factor affecting correction of pronation. Level of Evidence: Level IV, retrospective case series.
