ABSTRACT
Fractures of two columns of the acetabulum according to the Letournel classification are among the most common in frequency, indication and surgical complexity. These are mainly the result of lateral compression mechanisms and are characterized by originating a disconnected acetabulum from the axial skeleton. Its surgical treatment may include: isolated anterior or posterior approach; combined, at the same surgical time or not; or broad approaches. The authors present another surgical option with association of the Kocher-Langenbeck pathway with the iliac crest approach simultaneously and in the same positioning (lateral decubitus) based on the first three clinical cases performed and their clinical and imaging results. In addition to the presentation of the cases, a description of the three characteristic fragments of this type of acetabular fractures, the approach pathway, and the reduction sequence performed are made. From the results obtained and the associated advantages, the authors believe that the addition of the iliac crest approach to the Kocher-Langenbeck pathway may be a very attractive option to consider in the surgical treatment of properly selected fractures of two columns of the acetabula.
ABSTRACT
The authors present a case of fibroma of the tendon sheath with intra-articular location in the knee, more specifically in the infrapatellar fat; with this specific location, this is the fourth case described of an entity that rarely affects large joints. Clinical and epidemiological aspects, but especially the imaging findings on magnetic resonance imaging scans, are essential for the differential and definitive diagnosis, which was nevertheless established only after a histological study of the excised mass by miniarthrotomy.

Resumo Os autores apresentam um caso de um fibroma da bainha de tendão com localização intra-articular no joelho e origem na gordura infrapatelar. Esta localização específica é extremamente rara, sendo este o quarto caso descrito de uma entidade que raramente afeta grandes articulações. Para o seu diagnóstico aspetos clínicos, epidemiológicos e sobretudo achados imagiológicos da ressonância magnética são fundamentais. Neste caso o diagnóstico definitvo foi apenas estabelecido após estudo histológico da massa excisada por mini-artrotomia.
