Atualização da anatomia do mecanismo extensor do joelho com uso de técnica de visualização tridimensional

Abstract

The knee extensor mechanism is a complex structure formed by the quadriceps muscle and tendon, the patella, the patellar tendon and the ligaments that surround and help stabilize the knee. Through using a three-dimensional viewing technique on images of the knee extensor apparatus, we aimed to didactically show the structures that compose this bone-muscle-ligament complex. Anatomical dissection of the knee with emphasis on the structures of its extensor mechanism was performed, followed by taking photographs using a camera and lenses suitable for simulating human vision, through a technique for constructing three-dimensional images. Then, with the aid ofThe authors declare that there was no conflict of interest in conducting this work this article is available online in portuguese and english at the websites: www.rbo.org.br and www.scielo.br/rbort appropriate software, pairs of images of the same structure from different angles simulating human vision were overlain with the addition of polarizing layer, thereby completing the construction of an anaglyphic image. The main structures of the knee extensor mechanism could be observed with a three-dimensional effect. Among the main benefits relating to this technique, we can highlight that in addition to teaching and studying musculoskeletal anatomy, it has potential use in training for surgical procedures and production of images for diagnostic tests.

“…Os meniscos se ligam por um pequeno ligamento, chamado de ligamento transverso (De Castro, 2009) e sua vascularização é originada dos vasos geniculares laterais e mediais (superiores e inferiores) (Astur, 2011).…”

“…O joelho possui vários músculos acessórios, como gastrocnêmio, poplíteo e sartório, além de alguns músculos que atuam de forma direta na articulação, como quadíceps femoral, ísquio-sural, grácil, tensor da fáscia lata (Lemos, 2016).
