          Abstract

          Introducción: El objetivo de este estudio fue analizar los resultados radiológicos de una osteotomía en tejadillo (Chevron) del primer metatarsiano, con técnica mínimamente invasiva, en una población uniforme de pacientes (hallux valgus moderado). Materiales y Métodos: Entre octubre de 2013 y noviembre de 2014, se trató el hallux valgus mediante una osteotomía en tejadillo (Chevron) del primer metatarsiano con técnica mínimamente invasiva, en 24 pies correspondientes a 21 pacientes, todos con diagnóstico de hallux valgus moderado. Resultados: El ángulo intermetatarsiano preoperatorio promedio entre el primero y el segundo metatarsiano fue de 12,46° (rango 11-15°; desviación estándar 1,03). En el posoperatorio, se obtuvo un valor promedio de 8,13° (rango 5-10°; desviación estándar 1,16). La corrección angular promedio fue de 4,33°. El ángulo de hallux valgus preoperatorio promedio fue de 33,96° (rango 20-40°; desviación estándar 4,93). En el posoperatorio, el ángulo metatarsofalángico promedio fue de 8,16° (rango 3-15°; desviación estándar 2,86). La mejoría promedio del ángulo metatarsofalángico fue de 25,86°. Conclusiones: La corrección radiológica obtenida mediante la técnica mínimamente invasiva de la osteotomía en tejadillo confirma que es un procedimiento seguro y eficaz para el tratamiento del hallux valgus moderado, con correcciones angulares satisfactorias a mediano plazo. Este procedimiento remeda, de manera fidedigna, la técnica quirúrgica abierta con todos sus beneficios conocidos y no se encontró un estudio equivalente en la bibliografía.

          Introduction: The aim of this study was to analyze the radiological results of a roof (Chevron) osteotomy with a minimally invasive surgery technique of the first metatarsal in a uniform population of patients with moderate hallux valgus. Methods: Between October 2013 and November 2014, the hallux valgus was treated with a roof (Chevron) osteotomy using a minimally invasive technique of the first metatarsal in 24 feet of 21patients. All had a diagnosis of moderate hallux valgus. Results: The mean preoperative intermetatarsal angle between M1 and M2 was 12.46° (range: 11-15°, SD 1.03). Postoperatively, the mean intermetatarsal angle was 8.13° (range: 5-10°; SD 1.16), with an average angular correction of 4.33°. The mean hallux valgus angle was 33.96° (range: 20-40°; SD 4.93) before surgery and the average postoperative metatarsal-phalangeal angle was 8.16° (range: 3-15°, SD 2.86), thus improving an average of 25.86°. Conclusions: Radiological results with the minimally invasive technique (Chevron osteotomy) confirm that this procedure is safe and effective for the treatment of moderate hallux valgus, with mid-term satisfactory angular correction. This method reliably mimics the open Chevron surgical technique retaining all its known benefits. To our knowledge, no equivalent study was found in the literature.

          Radiographic results after percutaneous distal metatarsal osteotomy for correction of hallux valgus deformity.

          The goal of the study was to evaluate the short-term radiographic results and complications of a percutaneous distal metatarsal osteotomy for hallux valgus. From June, 2005, until October, 2005, a percutaneous distal first metatarsal osteotomy was performed in 13 consecutive patients. All patients had mild to moderate hallux valgus deformities preoperatively. The mean postoperative followup was 130 (range 50 to 207) days. The radiographs were reviewed for hallux valgus angle, 1-2 intermetatarsal angle, nonunion, malunion, and osteonecrosis. The mean 2 weeks postoperative hallux valgus angle demonstrated a statistically significant (p < 0.0001) improvement from 25 (16 to 33) degrees preoperatively to 5 (-1 to 12) degrees postoperatively. Nine patients (69%) demonstrated dorsally angulated alignment of the first metatarsal at the first postoperative examination averaging 10.8 (6 to 15) degrees that increased to 15.9 (10 to 22) degrees at final followup. One patient developed cystic changes within the metatarsal head consistent with osteonecrosis. One patient developed a nonunion with no evidence of radiographic healing at most recent followup of 180 days. Five patients (38%) had recurrent hallux valgus defined as a final angle of greater than 15 degrees. Percutaneous distal metatarsal osteotomy for hallux valgus is associated with an unacceptable rate of complications, specifically, osteonecrosis, nonunion, malunion, and recurrence. The intraoperative correction was routinely lost after removal of the intramedullary Kirschner wire, leading to a high rate of recurrence of hallux valgus deformity as well as dorsal elevation of the capital fragment.

            Percutaneous hallux valgus surgery: a prospective multicenter study of 189 cases.

            Distal first metatarsal osteotomies have been indicated for the correction of mild-to-moderate hallux valgus deformity. The aim of this study was to assess the clinical and radiographic results of the distal Reverdin-Isham first metatarsal osteotomy with use of a percutaneous procedure after a minimum 1-year followup. One hundred eighty-nine feet in 168 consecutive subjects were included in the present prospective multicenter study. A radiographic and clinical assessment using the American Orthopaedic Foot and Ankle Society's (AOFAS) hallux-metatarsophalangeal-interphalangeal scale was performed for all the subjects with a minimum 1-year follow-up. One hundred fifty six subjects (87%) were satisfied or very satisfied with the outcome of the procedure. The median postoperative AOFAS score was 93 points. Subjects averaged a loss 17% of first metatarsophalangeal joint motion. The median hallux valgus angle and intermetatarsal angle improved from 28 degrees and 13 degrees preoperatively, to 14 degrees and 10 degrees postoperatively, respectively. Percutaneous correction of mild-to-moderate hallux valgus deformity with the Reverdin-Isham osteotomy of the first metatarsal enables us to achieve clinical and radiographic results comparable to other percutaneous or open distal metatarsal osteotomies after 1-year follow-up.

              A new osteotomy for hallux valgus: a horizontally directed "V" displacement osteotomy of the metatarsal head for hallux valgus and primus varus.

              A new operation for hallux valgus consists of a horizontally directed "V" displacement osteotomy done in the head of the first metatarsal. This procedure corrects most of the primus varus, the valgus tilt of the articular surface of the first metatarsal and, if present, the axial rotation of the great toe. The osteotomy is combined with a release and balancing of soft-tissue structures on both sides of the joint. No casting and usually no internal fixation is necessary. Ambulation is generally recommended on the third postoperative day. The operative techniques, indications for surgery, clinical material, and postoperative care are discussed. The operation, when done correctly, does not result in recurrence of the deformity. Significant complications are rare.
