ABSTRACT
The reconstruction of the injured tissue around the knee is a complex procedure for the plastic and orthopaedic surgeon. The objective is to provide an acceptable function and aesthetic result. Successful wound management includes meticulous debridement, planning and proper execution of the surgical procedure. An 11-year-old male patient with a right patellar fracture using an anterolateral thigh flap with reverse flow to cover the skin defect. For such purposes, the reverse flow anterolateral flap is an effective, trustworthy and well-documented option. The correct obtaining and implantation of the flap reduces the morbidity of the donor site, offers options in size and design, an adequate length of the pedicle and the possible combination with the fascia lata in case it is required. The versatility of the reverse flow anterolateral flap makes it a possible therapeutic alternative in reconstructive surgery since it is aesthetic and functional for the reconstruction of tissue near the knee joint.
ABSTRACT
Background: The concept of angiosome explains the anatomical variations that exist between the vessels of different regions of the body and helps to understand the contributions of arterial blood supply to the skin and adjacent structures, dividing the human body into three-dimensional vascular blocks.Methods: This was an observational and descriptive study. In both lower extremities of 5 corpses with adequate tissue preservation in the operating room attached to the teaching area of the National Institute of Forensic Sciences in Mexico City. Angiosome study of the medial neurocutaneous flap of the second toe of both feet was performed.Results: The average, in centimeters, of the surface of the flaps was 1.57 cm x 2.47 cm, the average diameter of the inter-metatarsal digital artery was 1.1 millimeters and the average diameter of the veins draining the angiosome was 1.4 millimeters. The most constant anatomy was that of the nerve, which was present in all cases, with the digital nerve forming the neurosome of the flap.Conclusions: To obtain optimal results in microsurgery transfers, it is necessary to have a technique that is quick for harvesting the flap and with adequate systematization so as not to injure the neurovascular bundle, this is achieved through complete anatomical knowledge, without forgetting the main variants.
