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.

Objective: To measure and evaluate the distance from the medial plantar nerve (MPN) to six predetermined anatomical landmarks, identifying 12 distances, and establish a correlation with the trajectory of the flexor hallucis longus (FHL) tendon, especially the knot of Henry, and the location of the bifurcation of the posterior tibial nerve (PTN) relative to the tarsal tunnel. Methods: A descriptive and quantitative study was conducted in which 15 adult feet (six right and nine left) from cadavers were dissected, and the anatomical relationship between the MPN and predetermined structures was evaluated. The distance from the medial border of the medial malleolus to the inferior calcaneal tuberosity [defined as a fixed reference (FR)] was measured to compensate for variability in foot size. Results: The results indicated that the bifurcation of the PTN was proximal to the tarsal tunnel in 11 feet (73.3%), within the tunnel in three feet (20%), and distal to the tunnel in one foot (6.66%). A statistically significant (p=0.035) association was found between the FR and the distance from the superior calcaneal tuberosity to the MPN, a strong correlation (p=0.004) was found between the FR and the distance from the inferior calcaneal tuberosity to the MPN, and a significant association (p=0.013) was found between the FR and the distance from the medial calcaneal tuberosity to the knot of Henry. Conclusion: Some anatomical structures, especially the knot of Henry, have a strong correlation with the MPN and should be considered by surgeons who intend to approach the FHL in the plantar region. Bifurcation of the PTN proximal to the tarsal tunnel was the most common presentation.Level of Evidence V; Expert opinion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
