Osteointegración con el sistema Keep Walking Advanced® en una paciente amputada transfemoral / Osseointegration with the Keep Walking Advanced® system in a transfemoral patient

Aproximadamente una tercera parte de los pacientes con una amputación transfemoral van a padecer problemas crónicos relacionados con el encaje de su prótesis. El 72% de los pacientes amputados refieren sudoración o sensación de calor por culpa del encaje, el 62% reportan lesiones cutáneas o irritaciones de la piel del muñón, el 53% fatiga del muñón, el 51% dolor del muñón y el 38% acaban abandonando el uso de la prótesis. La osteointegración es una técnica que evita estos problemas generados en la piel del paciente, ya que permite un anclaje directo de la prótesis al implante intramedular colocado en el fémur del paciente. Presentamos el caso de una paciente amputada transfemoral de 38 años tratada mediante una cirugía de osteointegración con el implante Keep Walking Advanced® para mejorar el uso de la prótesis sin la necesidad de encaje (AU)

Approximately one third of patients with a transfemoral amputation will have chronic problems related to the fitting of the prosthesis. More than two thirds (72%) of amputees report sweating or feeling hot because of the socket, 62% report skin lesions or skin irritation of the stump, 53% stump fatigue, 51% stump pain and 38% do not use the prosthesis. Osseointegration is a technique that avoids these problems in the patient's skin, allowing direct anchoring of the prosthesis to the intramedullary implant placed in the patient's femur. We report the case of a 38-year-old transfemoral amputee who underwent implantation of the Keep Walking Advanced® implant to improve the use of the prosthesis without the need for socket fitting (AU)

Microvascular reconstruction of the mandible in irradiated patients.

This work focuses on the use of revascularized free flaps for the reconstruction of the major defects of the mandible after the removal of advanced-stage tumors in irradiated patients. It uses three representative cases to study the problems of complex patients and the possible reconstructive options. The cases, all three young patients (two females and one male), had undergone a mandibulectomy and adjuvant radiotherapy for malignant neoplasms. In each case, secondary reconstruction of the mandible and soft tissue was necessary and was performed using microvascular free flaps. An osteomyocutaneous iliac crest free flap was used in two cases, whereas a double flap (fibula free flap + rectus abdominis free flap) was used in the other case. In all three cases, after the microvascular reconstruction, an orthognathic procedure was performed to obtain the correct maxillomandibular relationship. The advantages and disadvantages of the various techniques used are discussed.

Use of a pedicled parascapular flap for anterior shoulder and arm reconstruction.

We present a case of soft-tissue reconstruction of the shoulder and upper arm utilizing a pedicled parascapular flap and discuss its potential as a flap for regional reconstruction.
