“…Nonetheless, previous studies have shown good intrarater reliability with mean Kappa values between 0.70 and 0.75. 18,22 In conclusion, postoperative TSP was a predictor of functional outcome and patient satisfaction with the surgery, with an abnormal TSP resulting in poorer functional outcome and patient satisfaction. Conversely postoperative HVA and IMA were not found to influence patient satisfaction.…”

“…operations. In several articles, the location of the sesamoid medially with rotation in hallux valgus was a predictor of recurrence [ 12 , 22 , 24 , 25 , 26 , 27 ]. The lateral displacement of the sesamoids is believed to be related to the post-operative recurrence of hallux valgus; however, we are not aware of any previous studies in which the relationship between two different surgeries and the recurrence of hallux valgus on plain radiograph in the early and most recent follow-up was investigated.…”

Background: The purpose of the present study was to compare the degree of sesamoid reduction after hallux valgus correction between distal chevron metatarsal osteotomy (DCMO) and S.E.R.I. (simple, effective, rapid, and inexpensive) osteotomy, and to analyze the effects on the recurrence of hallux valgus. Methods: We retrospectively analyzed the foot radiographs of 60 feet (30 DCMO and 30 SERI) treated for hallux valgus from August 2013 to July 2017. Radiographic assessments were performed preoperatively, at early follow-up (at a mean of 3.1 months) and at the most recent follow-up (at a mean of 16.7 months). The location of the medial sesamoid was classified into seven stages, in accordance with the method described by Hardy and Clapham; stage IV or less was defined as the normal position for the medial sesamoid, and stage V or greater was defined as lateral displacement of the sesamoid. The pre- and post-operative hallux valgus angle, 1–2 intermetatarsal angle, and sesamoid position were compared between the two groups. Results: The mean follow-up period was 18.4 (12–36) months in the DCMO group and 15.0 (12–36) months in the S.E.R.I. group (p = 0.108). The radiologic results showed that the hallux valgus angles were not significantly different between the two groups preoperatively and at the early follow-up: preoperatively, they were 28.8 ± 7.7 in the DCMO group and 32.6 ± 9.5 in the S.E.R.I. group (p = 0.101), and they were 10.4 ± 4.0 and 8.7 ± 5.0 (p = 0.148) at the early follow-up, respectively. However, at the most recent follow-up, the DCMO group (13.9 ± 5.6) showed significantly higher hallux valgus angles than the S.E.R.I. group (10.4 ± 6.4, p = 0.030), and there were no differences between the recurrence of hallux valgus in the DCMO group (13%)and that in the S.E.R.I. group (10%) (p = 0.553). There were no significant differences in the 1–2 intermetatarsal angles between the two groups at the early follow-up (6.1 ± 2.5 vs. 4.8 ± 3.1, p = 0.082) and at the most recent follow-up (7.3 ± 2.9 vs. 6.6 ± 3.5, p = 0.408). After hallux-valgus-correction surgery, the stage change of the tibia sesamoid position from the preoperative stage to the initial follow-up was significantly larger in the S.E.R.I. group (−4.4 ± 1.4) than in the DCMO group (−3.4 ± 1.1) (p = 0.003); the changes from the preoperative stage to the last follow-up were also significantly larger in the SERI group (−3.3 ± 1.7) than in the DCMO group (−2.4 ± 1.5) (p = 0.028); however, the changes from the initial follow-up to the last follow-up showed no significant differences between the two groups (+1.0 ± 1.1 in the DCMO group vs. +1.1 ± 1.2 in the S.E.R.I. group) (p = 0.822). The medial sesamoid was laterally subluxated in all the preoperative cases in the DCMO and S.E.R.I. groups. The lateral subluxation of the tibia sesamoid was more frequently observed in the DCMO group (four cases, 13%) than in the S.E.R.I. group (0 cases, 0%) (p = 0.038) at the early follow-up. Conclusion: In conclusion, our results demonstrated that the S.E.R.I. procedure is superior to DCMO in decreasing the hallux valgus angle and showed that the early post-operative reduction in the sesamoids can be a risk factor for the recurrence of hallux valgus.

“…32 Subluxation of the lateral sesamoid was graded from 0 to 3. 1,3,25 Shortening of the first metatarsal bone was measured by comparison with the length of the second metatarsal bone using Morton's method. 2,24 Considering the possibility of weak bone quality, radiologic abnormalities such as malunion, delayed union, significant shortening, hardware failure, and callus formation at the osteotomy site were evaluated.…”

Background: The purpose of this study was to compare radiographic outcomes of simultaneous bilateral and unilateral distal chevron metatarsal osteotomy (DCMO) in hallux valgus patients aged ≥60 years. Methods: This retrospective study analyzed consecutive outcomes of simultaneous bilateral DCMO and unilateral DCMO performed between June 2010 and August 2018 in 90 feet of 60 patients. Thirty patients underwent simultaneous bilateral DCMO, and 30 underwent unilateral DCMO. Comparative analysis of radiographic and clinical parameters between a simultaneous bilateral DCMO group (SB) and a unilateral DCMO group (U) was performed. Results: Mean age at surgery (65.7±4.8 vs 65.2±5.2 years), mean length of follow-up period (20.0 vs 18.6 months), and preoperative radiographic parameters were similar between the 2 groups (SB vs U). Mean hallux valgus angle (HVA) improved from 34.2 to 5.4 degrees (correction angle SB 28.8 vs U 28.8 degrees). Mean first-to-second intermetatarsal angle improved from 15.8 to 6.8 degrees (correction angle SB 8.9 vs U 8.9 degrees). Hallux varus deformity was observed in 4 feet (SB 3 vs U 1), and mechanical instability with callus formation in 1 foot in the unilateral group. Conclusions: DCMOs in patients aged ≥60 years were radiographically effective and safe, even performed in one stage bilaterally. Radiographic parameters were similar in patients who underwent simultaneous bilateral and unilateral DCMO. Level of Evidence: Level III, retrospective cohort study.
