“…For example, for patients with severe hallux valgus accompanied by increased DMAA, Double metatarsal osteotomy (DMO) was a quite effective operating method [10] . But in fact, due to its own complications such as shortening the length of the rst metatarsal bone, postoperative avascular necrosis of the metatarsal head, and metastatic metatarsalgia, the application of this technique was limited to a certain extent [11] .

Background The congruency of the first metatarsophalangeal (MTP) joint was extremely important for the selection of operating methods and prognosis, while its radiographic evaluation method was relatively lacking. The purpose of this article was to explore the radiographic indicators for evaluating the congruency of the first MTP joint. Methods The patients who had X-ray of weightbearing in the outpatient system were selected, excluding patients with trauma, deformity, and history of operation. 183 patients with 245 feet were included. The hallux valgus angle (HVA), distal metatarsal articular angle (DMAA), metatarsophalangeal joint angle (MTPJA), congruency index (CI) and tibial sesamoid position (TSP) were measured and do statistical analysis. Results The higher the degree of hallux valgus, the higher the proportion of incongruency of the first MTP joint. Significant differences were found in DMAA, MTPJA and CI between the congruency and incongruency groups of patients with moderate to severe hallux valgus (P < 0.05). The area under curve (AUC) of the receiver operating characteristic(ROC) curve for MTPJA and CI was 0.906 and 0.884, the sensitivity and specificity reached 0.791 and 0.862, 0.949 and 0.644, and the critical values were 10.67 and 0.765 respectively. The correlation test indicated that in the congruency group, DMAA and HVA had positive correlation, but MTPJA, CI and HVA had low correlation coefficients. DMAA and HVA were not correlated in the incongruency group, while MTPJA and HVA were significantly positively correlated, and CI and HVA showed a negative correlation (P < 0.05). Conclusion MTPJA and CI are indicators that can quantitatively evaluate the congruency of the first MTP joint, taking 10° and 0.765 as the demarcation points respectively. Clinically, the congruency of MTP joint should be considered when choosing operating methods for different degrees of hallux valgus, MTPJA and CI can be used as quantitative evaluation indicators.

Objective: To present a novel method called triplanar chevron osteotomy to treat hallux valgus (HV). Methods: This is a retrospective study. In this study, the CT data of HV patients with painful callosities were evaluated retrospectively between 1 June 2018 and 1 June 2020. CT data from 49 consecutive patients (59 feet) with HV were evaluated. The average age at the time of surgery was 49.6 years (range, 30-63 years). The apex of the chevron osteotomy procedure was located at the center of the first metatarsal and was defined as the line formed by the central point perpendicular to the fourth metatarsal bone. The cut planes of the plantarward oblique chevron osteotomy (POCO) were defined as follows: chevron osteotomy along with 20 of plantarward obliquity. The triplanar osteotomy incision was made using the POCO method, with the direction inclined by 10 distally. The intermetatarsal angle (IMA), the HV angle (HVA), the projection of the second metatarsal (PSM), the metatarsal protrusion index (MPI), and the metatarsal protrusion distance (MPD) were all calculated before and after the operations. The length of the first metatarsal was measured and calculated with an equation. Results: The results showed that the HVA was significantly decreased after surgery (32.7 AE 4.6 vs 14.9 AE 2.1 , t = 25.583, P < 0.001) in the triplanar, traditional, and POCO groups. The IMA was also significantly decreased (14.7 AE 2.0) compared with the results before surgery (8.0 AE 1.1 , t = 22.739, P < 0.001) in these groups. Compared with traditional osteotomy and POCO, there were no differences in correcting deformities on axial planes for the HVA (14.5
