“…The upper limits of the hallux abductus angle (HAA) in which a good result can be obtained have been consistent, being somewhere in the 30° ± 5° range [11]. Similarly, angles greater than 40° have been reported to be associated with poor results [9]. The average amount of correction of hallux abductus with the Mitchell's osteotomy is dependent on the surgeon performing the operation.…”

“…The average amount of correction of hallux abductus with the Mitchell's osteotomy is dependent on the surgeon performing the operation. Averages of correction have been stated in the literature, but they have appeared very sporadically [1][2][3][4][5][6][7][8][9][10][11][12][13].…”

“…Although the metatarsal head is often intrinsically stable with step-cut Mitchell's osteotomy, secure existence of new techniques, Mitchell's osteotomy in the treatment of Hallux valgus remains to be used in our era and indications has expanded from mild to moderate hallux valgus surgery, to moderate and severe hallux valgus surgery [1,9] this partly is because of the simplicity of the technique and relative stability of the osteotomy regardless of whether internal fixation or suture fixation, is used.…”

“…No intraoperative X-ray is used, the correction of the deformity was assessed mainly on appearance and the percentage of displacement (Figure 3). wire fixation, Herbert screw, A-O screws and other techniques [4][5][6][7][8][9]. The advocates of internal fixation claim that the stability of the Mitchell procedure is compromised when relying on the lateral spicule, soft tissue, and splinting techniques to maintain correction.…”

Background: The fixation method of Mitchell's osteotomy after displacement is controversial. In the current study, we evaluated a previously described technique of using transosseous capsulorrhaphy. In this series, foot plaster slipper was used for six weeks. Material and methods: Twenty-seven feet (21 patients) underwent the technique for symptomatic hallux valgus was included in this study. Retrospective and consecutive series. Mitchell's step cut osteotomy was performed without metal fixation, trans osseous capsulorrhaphy was used for fixation. Results: At 15 months follow-up, the results were satisfactory in 23 feet, fair in three patients and poor in one patient. Mean HVA correction was 17° and IMA correction of 5.4° this is considered to be significant. Conclusion: The main advantage of the described technique is that it can be used in a less sophisticated surgical unit, without the need for internal fixation implants and image intensifier.

Introduction The hallux valgus deformity is a complex deformity of the first ray of the foot, with more than 100 procedures developed for its treatment. The aim of this retrospective study was to assess the clinical and radiographic outcomes of a modified Mitchell's technique. Methods Between 2007 and 2018, 75 patients underwent the procedure. Clinical results were assessed by the AOFAS score. Radiological studies were evaluated by measuring pre-operative and post-operative HVA and IMA angles as well as the relative shortening of the first metatarsal. Results Of the initial 75 patients, 42 patients remained eligible with a total of 67 feet. The mean age and follow-up were 47.8 and 5.2 years respectively. Global AOFAS score improved from 45.3 to 88.8 (p < 0.01). Mean HVA and IMA improved from 37.0 to 10.2 (p < 0,01) and 12.1 to 5.6 (p < 0.01), respectively. The mean metatarsal shortening was 3.0 mm (p < 0.01). The statistical analysis showed no significant correlation between preoperative HVA and IMA angles with postoperative shortening, metatarsalgia, AOFAS scores nor the difference between the preoperative and postoperative AOFAS scores. Conclusion Short- and long-term outcomes of this modified Mitchell's osteotomy have been reported. Compared to other studies, these modifications proved to result in very good clinical and radiological outcomes even in severe cases with HVA>40. It has shown to be reliable, reproducible, and cost-efficient with low complication rates. We would like to highlight the importance of proper patient selection, limited soft tissue stripping, and adherence to the proposed surgical steps to avoid unwanted complications.
