RESUMO

La deformidad en equino del tobillo ocurre como consecuencia de múltiples entidades. Aunque la primera línea de tratamiento es la conservadora, las modalidades quirúrgicas son necesarias en la mayoría de los enfermos pediátricos. Estas últimas son las más empleadas por zonas del complejo músculo-tendinoso, en especial los alargamientos fraccionados y en forma de Z-plastia. El objetivo de este trabajo es actualizar y brindar información sobre los distintos procedimientos quirúrgicos en la corrección de la deformidad en equino del tobillo. En la búsqueda y análisis de la información se emplearon las siguientes palabras: equinus deformity, equino varus, equino valgus; drop foot deformity y Achilles tendon Z-lengthening. A partir de la información obtenida, se realizó unala revisión bibliográfica de un total de 187 artículos publicados en las bases de datos PubMed, Hinari, SciELO, EBSCO, Scopus, Medscape y Medline, mediante el gestor de búsqueda y administrador de referencias EndNote. De ellos se utilizaron 30, 28 de los últimos cinco años. Se hace referencia a la anatomía esencial de la zona, al igual que a la prueba de Silfverskiöld. Con relación a la imagenología, se describe la técnica para calcular la distancia del tendón a alargar. Se mencionan las técnicas quirúrgicas de alargamiento fraccionado, por Z-plastia, trasposición anterior del tendón de Aquiles y la hemiepifisiodesis.


Equinus deformity of the ankle occurs as a consequence of multiple entities. Although the first line of treatment is conservative, surgical modalities are necessary in most pediatric patients. The latter are the most used for areas of the muscle-tendinous complex, especially fractional and Z-plasty-shaped lengthening. The aim of this work is to update and provide information on the different surgical procedures in the correction of equinus deformity of the ankle. In the search and analysis of the information, the following words were used: equinus deformity, equinovarus, equinovalgus; drop foot deformity and Achilles tendon Z-lengthening. Based on the information obtained, a bibliographic review of a total of 187 articles published in PubMed, Hinari, SciELO, EBSCO, Scopus, Medscape and Medline databases was carried out using the search manager and reference administrator EndNote. Of these, 30 were used, 28 of the last five years. Reference is made to the essential anatomy of the area, as well as to the Silfverskiöld test. In relation to imaging, the technique to calculate the distance of the tendon to be lengthened is described. Fractional lengthening surgical techniques are mentioned, by Z-plasty, anterior transposition of the Achilles tendon and hemiepiphysiodesis.

RESUMO

The objective of this investigation was to analyze the surgical anatomy of the endoscopic gastrocnemius recession procedure with reference to the curved nature of the aponeurosis. A consecutive series of 34 magnetic resonance imaging scans were evaluated under the direction of a musculoskeletal radiologist. An angular calculation of the effective curvature of the aponeurosis was measured 2 cm distal to the musculotendinous junction based on the maximal posterior excursion and terminal medial and lateral edges. A frequency count was additionally performed of the number of deep intramuscular septa extending from the aponeurosis, as well as a description of the location of the neurovascular bundle in this location. The mean effective curvature was 126.5 degrees (standard deviation [SD] = 6.3 degrees, range 115-143 degrees, 95% confidence interval 124.3-128.7 degrees). We observed an average of 1.2 (SD = 0.5, range = 0-2) deep intramuscular septa extending from the aponeurosis, and that 20.6% of neurovascular bundles were located superficial to the aponeurosis in this location. In conclusion, we found that a straight cannula needs to be navigated around an approximate 125-degree angle during performance of the EGR procedure. We think that this information provides evidence of potentially unrecognized complications of this procedure and leads to future investigations demonstrating anatomic and procedural outcomes.

RESUMO

Complications of diabetes mellitus constitute the most common indications for hospitalization and non-traumatic amputations in the USA. The most important risk factors for the development of diabetic foot ulcerations include the presence of peripheral neuropathy, vasculopathy, limited joint mobility, and pre-existing foot deformities. In our study, 500 diabetic patients treated for plantar forefoot ulcerations were enrolled in a prospective study from 2000 to 2008 at the Federal University of São Paulo, Brazil. Fifty-two patients in the study met the criteria and underwent surgical treatment consisting of percutaneous Achilles tendon lengthening to treat plantar forefoot ulcerations. The postoperative follow-up demonstrated prevention of recurrent foot ulcerations in 92% of these diabetic patients that maintained an improved foot function. In conclusion, our study supports that identification and treatment of ankle equinus in the diabetic population may potentially lead to decreased patient morbidity, including reduced risk for both reulceration, and potential lower extremity amputation.
