“…The mean shortening of the first metatarsal was 0.2 cm and the proportion of no pain or relief of pain was 91.8% (89/97). No relief and aggregation of pain occurred in 8.2% of their cases (8/97), which was higher than others have reported 6,10 .…”

Objective: To observe and evaluate the long-term results of minimal incision osteotomy for hallux abducto valgus. Methods:From February 1995 to May 1999, 372 cases (705 feet) with hallux abducto valgus were treated with minimal incision osteotomy. Seventy-nine patients (150 feet) were followed up for more than five years (mean 7.5; range, 5.3-13.2 years) after surgery. The preoperative and postoperative hallux abducto valgus angles (HVA), intermetatarsal angles (IMA), tibial sesamoid position (TSP), American Orthopaedic Foot And Ankle Society (AOFAS) score, range of movement of the first metatarsophalangeal joint and lateral metatarsalgia were observed, measured and evaluated.Results: Based on clinic curative effect evaluation criterion, 56 feet (37.3%) were excellent, 88 feet (58.7%) good, 6 feet Conclusion:Minimal incision osteotomy is a simple and reliable technique for treating hallux abducto valgus with minimal complications.

“…Mean IMA correction in other studies varied from 5 to 7.8, this study had a mean of 6.5 which is also similar to the previously reported findings [ 6 , 11 , 16 , 17 , 22 , [24] , [25] , [26] ].…”

“…This procedure is generally indicated in IMAs ≤20 as it is a distal osteotomy, however some surgeons performed it for HVA <40 (moderate hallux valgus) while others also performed it for HVA > 40 with good long-term results (severe hallux valgus) [ 14 , 18 , 19 ], which is also shown in a long term follow up study on more than 200 cases [ 17 ]. We believe that the above described modification is a viable option treatment even for severe hallux valgus deformities with HVA>40.…”

“…In Mitchell's original osteotomy, the fixation was done by the use of a cerclage wire, with a reported rate of nonunion and loss of correction ranging from 4 to 7%, which is linked to the fixation method which didn't guarantee a firm stabilization [ 6 , 16 ]. Several fixation techniques were later used for better fixation such as crossed pins, Steinman pins, screws, staples, and one K-wire medially buttressing the distal fragment [ 6 , 11 , 16 , 17 ].…”

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.

Long-term Results of Mitchell's Procedure for Hallux Valgus Deformity: A 5- to 20-year Followup in 204 Cases

Abstract: Mitchell's osteotomy was a reliable technique with successful outcome and low complication rate when performed with Kirschner wire fixation and lateral soft tissue release when appropriate. It may also be successfully performed with hallux valgus angles greater than 40 degrees.
