Toepfer A, Strässle M. The percutaneous learning curve of 3rd generation minimally-invasive Chevron and Akin osteotomy (MICA). Foot Ankle Surg 2022; 28:1389-1398. [PMID: 35882575 DOI: 10.1016/j.fas.2022.07.006] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Revised: 02/13/2022] [Accepted: 07/13/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND Minimally-invasive Chevron and Akin osteotomy (MICA) represents the third-generation percutaneous hallux valgus surgery which is characterized by an extra-articular osteotomy, stable internal fixation and a high potential for correction. Compared to other percutaneous techniques of the foot, MICA is generally regarded as an advanced and demanding surgical procedure with a flat learning curve. The aim of this study is to analyze a single-surgeons experience with his first 50 consecutive MICA procedures. METHODS Between May 2018 and February 2021, 50 consecutive MICA procedures performed by the author with the "K-wires-First technique" were prospectively analyzed focusing on surgery duration, number of fluoroscopies, correction results and surgery-associated complications. A modification of the original MICA technique as described by its inaugurators Redfern and Vernois allows the use of a standard-sized C-arm and aims to reduce revison rates and conversion to open surgery by placing the guidewires prior to performing the osteotomy. RESULTS The average surgery time for all MICA procedures was 46.8 min (SD 12.1, range 31-90 min). The average amount of fluoro shots required to perform MICA was n = 126.6 (SD 40.8, range 65-231). Comparing the preoperative and 6-week postoperative radiographs, the IMA decreased after MICA by a mean of 10.8° from 16.2° to 5.4° and the HVA by a mean of 22.1° from 30.6° to 8.5°. One case required intraoperative conversion to open hallux correction. There were 4 feet in three patients with secondary screw removal of the Chevron fixation due to prominent proximal screw tips. CONCLUSIONS Although the learning curve of 3rd generation MICA is flat and requires specific training and intensive practice, the rate of complications is not elevated compared to other percutaneous hallux valgus techniques. Strict adherence to the principles of 3rd generation MICA with stable fixation and meticulous intraoperative control of each surgical step helps to reduce surgery-associated complications. The learning curve showed a continous improvement in regard to surgery time and use of fluoroscopy. After 40 procedures, the surgery time consistently dropped under 45 min and required less than 100 fluoro-shots. The modified surgical technique may help reduce Chevron screw mal-positioning when using large C-arm fluoroscopy for this procedure.

Abstract
The pediatric flexible flatfoot is a common foot shape that is most often asymptomatic and may be a physiologic variant of normal. Surgery is only indicated when nonoperative interventions have failed to resolve symptoms. The goal of surgery is to alleviate symptoms by improving hindfoot alignment and restoring the medial arch while preserving joint mobility. This article focuses on the common bony techniques for surgical correction of the pediatric flexible flatfoot that has failed nonoperative management, including calcaneal, midfoot, and supramalleolar osteotomies and distal tibial hemiepiphyseodesis.

BMC Musculoskelet Disord 2021; 22:977. [PMID: 34814872 PMCID: PMC8609868 DOI: 10.1186/s12891-021-04855-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Accepted: 11/08/2021] [Indexed: 11/16/2022] Open
Abstract
Background Evans calcaneal lengthening osteotomy is used to treat symptomatic flexible flatfoot when conservative treatment fails. Grafts such as autologous iliac bone grafts, allografts, and xenografts are implanted at the osteotomy site to lengthen the lateral column of the hindfoot. This study aimed to present the outcomes of an autologous mid-fibula bone graft used for calcaneal lengthening in symptomatic pes valgus in adolescents. Methods We retrospectively examined 23 ft of 13 adolescents who underwent surgery between July 2014 and January 2018. The radiological and clinical outcomes (American Orthopaedic Foot and Ankle Society ankle-hindfoot scale scores) were assessed during a mean follow-up of 49.7 (range, 30.9–73.4) months. The mean distance of the lengthening site was measured to evaluate graft sinking or collapse. The Goldberg scoring system was used to determine the degree of union at the donor and recipient sites. Results The calcaneal pitch and the anteroposterior and lateral talo-first metatarsal (Meary) angles showed significant correction, from 14.4 to 19.6 (p < 0.001), and from 14.5 to 4.6 (p < 0.001) and 13.5 to 8.5 (p < 0.001), respectively. The mean distance of the lengthening site showed no significant change (p = 0.203), suggesting no graft sinking or postoperative collapse. The lateral distal tibial angle showed no significant difference (p = 0.398), suggesting no postoperative ankle valgus changes. Healing of the recipient and donor sites occurred in 23 and 21 ft, respectively. The American Orthopaedic Foot and Ankle Society ankle-hindfoot scores improved significantly, from 68.0 to 98.5 (p < 0.001). Conclusions Evans calcaneal lengthening using an ipsilateral mid-fibula bone autograft resulted in significant improvement in clinical and radiological outcomes without ankle valgus deformity. Hence, it could be a treatment option for lateral column calcaneal lengthening in adolescents.

Abstract
The progressive collapsing foot deformity is a complex three-dimensional deformity, including valgus malalignment of the heel. The medial displacement calcaneal osteotomy is an established surgical procedure reliably resulting in an efficient correction of the inframalleolar alignment. However, complications are common, including undercorrection of underlying deformity, progression of hindfoot osteoarthritis and/or deformity, and/or symptomatic hardware.

Abstract
INTRODUCTION Flexible flatfoot refers to the loss of the medial longitudinal arch of the foot on weight bearing and is associated with excessive heel eversion or forefoot abduction. Unless symptomatic, flexible flatfeet are best managed non-operatively. The calcaneo-cuboid-cuneiform osteotomy is a procedure that restores the anatomical shape of the foot without arthrodesis of the joints. Our study aims to evaluate the functional and radiological outcomes of patients treated with calcaneo-cuboid-cuneiform osteotomy in patients with planovalgus feet. METHODOLOGY A retrospective review of records and radiographs of patients with symptomatic flexible planovalgus feet, who were operated with the calcaneo-cuboid-cuneiform osteotomy by a single senior surgeon in a time period between April 2016 and July 2017 was done. The clinical and radiological outcomes were evaluated in 12 feet in 8 children. RESULTS A total of 12 feet in 8 children were operated (6 males and 2 females). Average age of patients was 11 ± 1.27 years; average follow up was 14.7 months ± 2.7 months. Two patients had planovalgus feet secondary to spastic diplegia and 6 had idiopathic planovalgus feet. There was a statistically significant improvement in the pain score as well as the radiographic parameters in all the operated patients. CONCLUSION The calcaneo-cuboid-cuneiform osteotomy has potential to give good results for symptomatic planovalgus feet with minimal complications.

INTERNATIONAL ORTHOPAEDICS 2019; 43:1179-1192. [PMID: 30701302 DOI: 10.1007/s00264-019-04303-3] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/03/2018] [Accepted: 01/21/2019] [Indexed: 12/20/2022]
Abstract
PURPOSE This systematic review aimed to compare radiographic correction, clinical outcomes, complications, and re-operations between lateral column lengthening (LCL) and arthroereisis (AR) for treating symptomatic flatfoot in children. METHODS We conducted a comprehensive search on MEDLINE, EMBASE, and Cochrane Library databases. Literature search, data extraction, and quality assessment were conducted by two independent reviewers. The outcomes analyzed included radiographic parameters, clinical scores, satisfaction, complications, and re-operations. RESULTS Twenty-one and 13 studies were included in the LCL and AR groups, respectively. The change in anteroposterior talo-first metatarsal angle was greater in the LCL (9.5° to 21.7°) than in the AR group (10.6° to 12.8°). The change in calcaneal pitch was greater in the LCL (2.1° to 26.53°) than in the AR group (- 1.3° to 3.23°). Improvements in the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score were greater in the LCL (27.7 to 39.1) than in the AR group (17 to 22). The percentage of satisfaction was similar between the LCL (68% to 89%) and AR (78.5% to 96.4%) groups. The complication rate was higher in the LCL (0% to 86.9%) than in the AR group (3.5% to 45%). The most common complications were calcaneocuboid subluxation and persistent pain in the LCL and AR groups, respectively. The re-operation rate was similar between the LCL (0% to 27.3%) and AR (0% to 36.4%) groups. CONCLUSIONS The LCL group has achieved more radiographic corrections and more improvements in the AOFAS score than the AR group. Complications were more common in the LCL group than in the AR group, and the re-operation rates were similar between the two groups.
