“…Em outro estudo similar, Ortiz et al (1) , em 2016, foram analisadas a variabilidade interobservador entre o AAC e o AIM, e a capacidade do AIM em diferenciar grupos que já haviam sido separados previamente usando o AAC como referência. Primeiro os autores concluíram que o AAC era mais fácil e rápido de ser medido e, por isso, mais reprodutível.…”

“…Para avaliar a correção da luxação dos sesamoides, foi quantificada, em graus, a lateralização do primeiro metatarso necessária para se obter a centralização dos sesamoides, estabelecendo um valor que consideramos "o ângulo a ser corrigido" (AAC), que representa a correção angular necessária para reposicionar a cabeça metatarsal sobre o complexo sesamoideo (1) .…”

“…Dentre os vários valores angulares que podem ser obtidos para o tratamento adequado do hálux valgo, o ângulo metatarsofalangiano de valgismo do hálux e o ângulo intermetatarsal parecem ter forte correlação com o aspecto clínico, apresentando-se com limites variáveis para determinar sua gravidade (1,2) . A subluxação dos sesamoides sobre a cabeça do primeiro metatarso é comumente encontrada, e constitui um aspecto importante na progressão da doença e no potencial para a recidiva da deformidade após a correção cirúrgica (3,4) Alguns estudos (3)(4)(5)(6) discorrem sobre a localização dos sesamoides em relação ao antepé, bem como sua relação com a cabeça metatarsal.…”

“…Deformidades dolorosas que não respondem satisfatoriamente ao tratamento clínico são elegíveis para correção cirúrgica (1) . Diferentes procedimentos foram descritos para tratar os vários graus de deformidades do hálux valgo (7,8) , e a artrodese da primeira articulação tarso-metatarso, descrita por Lapidus em 1934 (9) , encontra-se bem estabelecida e com grande aceitação ao longo das últimas décadas (10) .…”

Sesamoid complex angle correction after arthrodesis of the first cuneometatarsal joint in the treatment of hallux valgus

Objective: To evaluate the degree of sesamoid complex correction in patients with moderate and severe hallux valgus undergoing cuneometatarsal arthrodesis by comparing general pre- and postoperative values and also post-reduction outcomes between moderate and severe cases. Methods: The radiographs of 24 patients (83.3% females and 16.7% males) who underwent arthrodesis of the first cuneometatarsal joint wereretrospectively analysed. The patients’ mean age was 52.58 years. The metatarsophalangeal, intermetatarsal and sesamoid dislocation angles were measured on the preoperative and immediate postoperative radiographs, with the former measured in the standing position and the latter measured intraoperatively, all in the anteroposterior incidence. The first metatarsal lateralization necessary to centralize the sesamoids wasmeasured in degrees. We refer to this angle as the “angle to be corrected”. Results: We achieved sesamoid dislocation correction, reducing the indicated angles in relation to their preoperative values. Both moderate and severe cases showed statistically significant differences in angular correction after surgery, with p=0.018 and p<0.001, respectively. Comparing the moderate and severe cases, a statistically significant difference was observed preoperatively, with p=0.007; however, the results were not statistically significant postoperatively (p=0.227). Conclusion: We achieved effective correction of the ABC in terms of both the total patient sample and the isolated analysis of the moderate and severe groups. Preoperatively, the moderate cases had smaller angles than the severe cases, but both groups exhibited reductions in these angles in the postoperative period and had similar outcomes. Level of Evidence III; Retrospective Study.

“…This angle is obtained by measuring the divergence between the first and second metatarsal. The angle to be corrected is also measured, to get a more precise measure of how many degrees are needed to place the metatarsal head over the sesamoid complex 15. The main downside of any angular measurement, is the limited capacity to evaluate metatarsal malrotation, demonstrated by sesamoid subluxation.…”

More than 200 different surgical techniques exist for hallux valgus (HV). Some of them are designed for mild, moderate, or severe deformities depending on their correction power. Nevertheless, they all correct only the coronal and/or sagittal plane deformity. Just a handful of them correct the known axial malrotation that exists in most HV cases. This malrotation is one possible factor that could be the source of recurrence of an operated HV as it has been described. We describe a new technique which simultaneously corrects the metatarsal internal rotation and varus deformity by rotating the metatarsal through an oblique plane osteotomy. This is performed with no bone wedge resection. Also, there is a broader bone surface contact than on a transverse proximal osteotomy. This technique is easy to remember and relatively simple to perform in primary and revision cases. The authors results show that it is as safe and effective as other procedures, with some advantages to be discussed.Levels of Evidence: Diagnostic Level 5.
