ABSTRACT
Introducción: la osteotomía en chevron modificada ha estado presente en numerosos artículos que tratan sobre el tratamiento de los Hallux valgus moderados y severos. Se presenta nuestra experiencia mediante la cirugía percutánea. Objetivo: mostrar la efectividad de la osteotomía en chevron modificada mediante cirugía percutánea en el tratamiento de los Hallux valgus moderados y severos. Método: estudio retrospectivo de 28 pacientes intervenidos de Hallux valgus moderados y severos entre abril y diciembre de 2013, con una media de edad de 59 años. El seguimiento mínimo fue de 1 año de evolución. Se valoró el ángulo de Hallux valgus, el intermetatarsiano y el ángulo metatarso distal articular y se determinó la posición de los sesamoideos. La osteotomía en chevron se fijó con un tornillo canulado de doble rosca también de forma percutánea. Resultados: el ángulo de Hallux valgus pasó de 34,96° ± 9,8 en el preoperatorio a 12,6° ± 5,2 en el posoperatorio. El ángulo intermetatarsiano de 15,56° ± 3,2 en el preoperatorio se redujo a 10,44° ± 3,1 en el posoperatorio. El ángulo ángulo metatarso distal articular pasó de 21,20° ± 6,0 en el preoperatorio a 9,36° ± 6,5 en el posoperatorio. Conclusiones: la osteotomía en chevron modificada percutánea tiene resultados similares a los de la cirugía abierta, con la gran ventaja de no realizar incisiones en el pie, lo que disminuye complicaciones habituales como la infección. Es importante la curva de aprendizaje dado que no es una técnica exenta de complicaciones(AU)
Introduction: modified chevron osteotomy has been present in numerous articles dealing with the treatment of moderate and severe Hallux valgus. Our experience with percutaneous surgery is presented here. Objective: show the effectiveness of modified chevron osteotomy with percutaneous surgery in the treatment of moderate and severe Hallux valgus. Methods: a retrospective study was conducted on 28 patients undergoing moderate and severe hallux valgus from April to December 2013, with an average age of 59 years. Minimum follow-up period was 1 year of evolution. Hallux valgus angle, intermetatarsal and distal metatarsal joint angle were evaluated and sesamoid position was determined. Chevron osteotomy was fixed with a cannulated double threaded screw also percutaneously. Results: Hallux valgus angle increased from 34.96 ± 9.8° preoperatively to 12.6° ± 5.2 postoperatively. The intermetatarsal angle of 15.56° ± 3.2 preoperatively decreased to 10.44 ± 3.1° postoperatively. The distal metatarsal articular angle increased from 21.20° ± 6.0 preoperatively to 6.5 ± 9.36° postoperatively. Conclusions: percutaneous modified chevron osteotomy has similar results to those of open surgery, with the great advantage of not making incisions in the foot, reducing common complications such as infection. Learning curve is important since it is not free of complications(AU)
Introduction: l'ostéotomie en chevron modifiée a été présente dans nombreux articles abordant le traitement de l'hallux valgus modéré et sévère. Un nouveau traitement par chirurgie percutanée est présenté. Objectif: le but de ce travail est de montrer l'efficacité de l'ostéotomie en chevron modifiée par chirurgie percutanée dans le traitement de l'hallux valgus modéré et sévère. Méthode: Une étude rétrospective de 28 patients (âge moyen de 59 ans) traités pour hallux valgus modéré et sévère a été réalisée entre avril et décembre 2013. Le suivi minimal a eu un an de durée. On a évalué l'angle de valgus, l'angle intermétatarsien et l'angle articulaire distal métatarsien, et on a également déterminé la position des sésamoïdiens. L'ostéotomie en chevron a été fixée par vis canulé à double filetage par voie percutanée. Résultats: l'angle de valgus a changé de 34.96° ± 9.8 en préopératoire à 12.6° ± 5.2 en postopératoire. L'angle intermétatarsien est réduit de 15.56° ± 3.2 en préopératoire à 10.44° ± 3.1 en postopératoire. L'angle articulaire distal métatarsien a diminué de 21.20° ± 6.0 en préopératoire à 9.36° ± 6.5 en postopératoire. Conclusions: l'ostéotomie percutanée en chevron modifiée a des résultats similaires à la chirurgie ouverte. L'avantage le plus remarquable de cette technique est l'absence d'incisions importantes au niveau du pied, ce qui diminue la survenue des complications habituelles telles que l'infection. Toutefois, la courbe d'apprentissage est très importante, car cette technique n'est pas exceptée de complications(AU)

PURPOSE: In this study, we tried to develop the technique of osteotomy for hallux valgus. The new modified technique of osteotomy was accomplished with even more greater stability, accurate correction of the deformity and more effective than 'chevron' osteotomy in terms of correction of the deformity. MATERIALS AND METHODS: Between March 1998 and December 2001, 55 cases of new modified osteotomy for hallux valgus were performed for 39 patients, 16 of whom underwent operation of both feet. Operations were made for 34 women and 5 men whose average age was 46 years old (range, 20~71 years). Average follow up period was three years (range, 2~5 years), and during the follow up, the patients underwent physical examination and assessment with use of the American Orthpaedic Foot and Ankle Society's hallux-metatarso-phalangealinterphalangeal scale8) and standard foot radiographic measurements16). RESULTS: 37 patients (53 cases) out of 39 patients (55 cases) had no pain, good cosmesis, and all of the patients were satisfied with the results of the operation. Two had occasional mild discomfort. The average score according to the hallux-metatarso-phallangeal-interphalangeal scale8) was 93.2 points (range, 78~100 points). The average preoperative intermetatarsal angle was 14.4 degrees, which was decreased to 7.9 degrees after the osteotomy with an average correction of 6.5 degrees and The average preoperative hallux valgus angle was 34.1 degrees, which was decreased to 11.1 degrees after the osteotomy with an average correction of 23 degrees. This new modified technique would prevent the angulation or shortening at the osteotomy site and it was also even more stable at osteotomy site, and could do even more effective and accurate correction of the deformity than conventional Chevron osteotomy. CONCLUSION: New modified chevron osteotomy for the treatment of symptomatic hallux valgus was done in 55 cases, and the results were satisfactory in all cases. This method was more stable at the osteotomy site than conventional Chevron osteotomy and was also possible to do more accurate and more effective correction of the deformity. It was also easy to control the distal fragment of first metatarsal bone.

PURPOSE: We compared the result of a proximal metatarsal closed wedge osteotomy and soft tissue procedure with a modified chevron osteotomy and soft tissue procedure in the treatment of hallux valgus. MATERIALS AND METHODS: Between March 1999 and February 2003, we performed proximal metatarsal closed wedge osteotomy and soft tissue procedure on 17 feet (12 patients), and modified chevron osteotomy and soft tissue procedure on 12 feet (9 patients). RESULTS: According to Mayo clinic forefoot scoring system (FFSS), group 1, with proximal metatarsal closed wedge osteotomy, shows 67.2 points postoperatively and group 2, with modified chevron osteotomy, shows 68.5 points postoperatively. In group 1, the average correction of hallux valgus angle and intermetatarsal angle was 20.8 degrees and 4.8 degrees, respectively. In group 2, the average correction of hallux valgus angle and intermetatarsal angle was 19.9 degrees and 4.7 degrees, respectively. The average shortening was 3.15 mm in group 1 and 1.38 mm in group 2. CONCLUSION: We obtained relatively good clinical and radiographic result in this study. The effect on shortening of the first metatarsal was greater in the proximal metatarsal closed wedge osteotomy than modified chevron osteotomy, but the metatarsal shortening did not related with metatarsalgia. So, both techniques seems optimal surgical treatment for hallux valgus deformity.
