ABSTRACT

Covering soft tissue defects of the tibia is challenging, especially in the presence of underlying osseous trauma. The soleus muscle flap remains the treatment of choice for soft tissue defects in the middle third of the tibia. The flap is reliable and requires a relatively short operative time while maintaining minimal donor site morbidity. However, when the muscle flap is performed without a modified fasciocutaneous composite, it requires a split-thickness skin graft. Muscle flaps have the additional advantage of improving vascularity and fighting infection.

ABSTRACT

Introduction: A soft tissue defect considering the extent, location, depth and involved structures can be a complex task, leading to search for unusual reconstructive alternatives. Case report: Puerperal woman, 21 years, previously healthy, admitted for septic shock and skin necrosis of both extremities secondary to purpura fulminans. Escharectomy was performed and the final defect was 27 percent of total body surface, corresponding to necrotic areas of both superior and lower extremities. Is remarkable the presence of musculocutaneous perforating vessels thrombosis and segmental muscular necrosis in legs and interosseous muscles necrosis in hands. In upper extremity coverage was performed with dermoepidermal grafts. To cover peroneal malleolus and feet dorsum, whereas there were no regional or local alternatives, we realize a double DIEP flap. Flap elevation of bilateral DIEP flap was performed simultaneously for two surgical teams. The patient had no complications and was discharged with complete soft tissue coverage.


Introducción: Un defecto de cobertura extenso de extremidades inferiores (EEII), considerando ubicación, profundidad y estructuras involucradas es de una alta complejidad y puede llevar a buscar alternativas reconstructivas poco habituales. Caso Clínico: Paciente de 21 años, puérpera, ingresa por shock séptico y necrosis cutánea extensa de extremidades secundario a un purpura fulminans. Se realiza escarectomía y el defecto resultante es de 27 por ciento de superficie corporal, correspondiendo a zonas necróticas en ambas extremidades, superiores e inferiores. Destaca la presencia de trombosis de vasos perforantes musculocutáneos, necrosis muscular segmentaria en piernas y de musculatura interósea en manos. En extremidades superiores se realizó cobertura con injertos dermoepidérmicos. Para la exposición de ambos maléolos peroneos y dorso de pies, considerando que no existen alternativas locales ni regionales, se decide realizar un colgajo DIEP bilateral; se eleva en un tiempo, con dos equipos quirúrgicos simultáneos. La anastomosis microquirúrgica se realizó a los vasos tibiales de cada extremidad. La evolución postoperatoria fue favorable. La paciente es dada de alta en buenas condiciones generales, extubada, con cobertura cutánea completa.

ABSTRACT

Introduction: Calcaneal fractures are the most frequent tarsal bone fracture. A high complication rate has been reported for the L-shaped lateral calcaneus surgical approach. Coverage of the resulting defect can be challenging. The aim of this article is to report a case series and propose a new treatment algorithm. Materials and Methods: Between January 2011 and December 2013 ninety-five patients underwent a close calcaneus fracture surgery by lateral approach. Ten patients suffered from surgical wound complications. Defects were classified as small (< 2 cm), medium (2-5 cm) or big size (> 5 cm). Results: Small size defects were covered with local fasciocutaneous advancement and rotation flaps. Medium size defect were covered either with a distally based sural neurocutaneous flap or propeller flap based on peroneal artery perforators. A free flap was used in the big size defect presented. Mean follow-up was 16 month (range 5-41 month). Stable coverage was achieved in all cases and no revision surgery was needed. Conclusions: Soft-tissue complications associated to lateral approach for calcaneal fractures needs an ordered approach. The algorithm presented including propeller perforator flaps proved to be safe and useful.


Introducción: Las fracturas de calcáneo son las fracturas más frecuentes de los huesos del tarso. Diversos estudios han mostrado alta tasa de complicaciones del abordaje que requieren cobertura. El objetivo principal es presentar un nuevo algoritmo de tratamiento para estos defectos de cobertura. Material y Métodos: Entre el 2011 y el 2013 se operaron 95 pacientes con fractura cerrada de calcáneo. Diez pacientes presentaron defectos de cobertura de la herida operatoria. Los defectos se clasificaron en pequeños (< 2 cm), medianos (2-5 cm) y grandes (> 5 cm). Resultados: Se realizaron 11 colgajos en 10 pacientes. Seis pacientes presentaron un defecto pequeño y fueron tratados mediante colgajos locales; cuatro casos de defectos medianos se resolvieron mediante tres colgajos perforantes de arteria peronea de tipo propeller y un colgajo sural. Todos los defectos de la zona dadora, tanto en el colgajo sural como en los colgajos propeller, fueron cerrados de manera primaria sin requerir injertos. Hubo un defecto grande que fue necesario cubrir con un colgajo libre. El período de seguimiento promedio fue 16 meses, con un rango de 5 a 41 meses. En todos los casos se proporcionó una cobertura estable que no requirió revisiones. Conclusiones: Es necesario un enfrentamiento ordenado y protocolizado para resolver estos defectos. En nuestro trabajo, proponemos un algoritmo simple basándonos en el ancho del defecto, incorporando como alternativa el colgajo perforante pediculado tipo propeller para defectos medianos, con el cual se logran coberturas estables y planas, con cierre primario de la zona dadora.

ABSTRACT

La reconstrucción del pie y pierna representa un desafío para el cirujano. Se presenta el caso clínico de un paciente de 32 años con una úlcera maleolar externa en el tobillo izquierdo que se trató con un colgajo sural de flujo reverso. Describimos el tratamiento realizado, detallando la técnica quirúrgica. Posteriormente comentamos algunos conceptos relevantes que encontramos al realizar una revisión de la literatura. Se comentan las indicaciones, detalles de la técnica quirúrgica y las complicaciones de esta cirugía.


The reconstruction of the foot and leg are a challenge for surgeons. We present a clinical case of a 32 years patient with an external malleolar ulcer in his left ankle. We treated it with a distally based sural flap. In this article we describe the treatment done, detailing the surgical technique. Thereafter, we describe some relevant concepts founded in the literature. We describe the indications, details of the surgical technique and complications of this surgery.
