First Metatarsal Shortening and Sesamoid Position as Predictors of Postoperative Metatarsalgia After Hallux Valgus Surgery
Öz
Objective: To evaluate whether postoperative metatarsalgia following hallux valgus surgery can be predicted using preoperative clinical and radiographic parameters together with postoperative first metatarsal shortening and sesamoid position. Methods: This retrospective cohort study included 144 patients treated with distal chevron osteotomy combined with the McBride procedure between 2018 and 2023. Preoperative clinical and radiographic parameters, postoperative first metatarsal shortening, and sesamoid position were analyzed. Univariate and multivariate logistic regression analyses were performed to identify independent predictors. Model performance was assessed using calibration and discrimination metrics, and receiver operating characteristic analysis was used to determine optimal cut-off values. Results: Postoperative metatarsalgia developed in 63 patients (43.8%). Multivariate analysis identified first metatarsal shortening (OR=1.83, 95% CI: 1.31–2.68, p<0.001) and postoperative sesamoid position (OR=5.69, 95% CI: 2.50–14.4, p<0.001) as independent predictors. The model showed good performance (Nagelkerke R²=0.453; accuracy=79.2%). First metatarsal shortening ≥4.2 mm predicted metatarsalgia with high specificity (96.3%) and moderate sensitivity (57.1%), whereas postoperative sesamoid position showed high sensitivity (90.5%) and moderate specificity (51.9%). Conclusion: Postoperative structural changes, particularly first metatarsal shortening and postoperative sesamoid position, are key determinants of metatarsalgia following hallux valgus surgery. Preservation of first ray length and adequate sesamoid reduction may help optimize clinical outcomes. Further prospective studies are needed.
