 The present study aims to evaluate different methods of tibial fixation in the reconstruction of the anterolateral ligament (ALL). In addition, the present paper aims to compare the effectiveness of these methods and their mechanisms of failure in swine knees.  A total of 40 freshly frozen swine limbs were divided into 4 groups of 10 specimens, according to the tibial fixation technique used. In group A, the tibial fixation of the tendon graft was made through an anchor passing the graft. In group B, the tibial fixation was performed through a metal interference screw in a single bone tunnel. In group C, the tibial fixation included an anchor associated with a tendinous suture (but not with a wire crossing the tendon). In group D, two confluent bony tunnels were drilled and combined with an interference screw in one of them.  The lowest mean force (70.56 N) was observed in group A, and the highest mean force (244.85 N) was observed in group B; the mean values in the other 2 groups ranged from 171.68 N (group C) to 149.43 N (group D). Considering the margin of error (5%), there was a significant difference between the groups (  < 0.001).  Fixation with an interference screw in a single tunnel bone showed the highest tensile strength among the evaluated techniques.

Hindfoot aneurysmal bone cyst: report of two cases.

Rev Bras Ortop 2018 Mar-Apr;53(2):257-265. Epub 2018 Feb 23.

Instituto de Ortopedia e Traumatologia, Passo Fundo, RS, Brazil.

Osseous tumors of the hindfoot are not usual in the literature, the diagnosis in these cases is difficult and can often go unnoticed. Besides that, surgery and reconstruction are complicated due to the complexity of the local anatomy, which makes these lesions even more challenging for the orthopedic oncological professionals. On the following article two cases of aneurysmal bone cyst of the hindfoot are reported, as well as the alternatives and peculiarities in conducting these cases according to the oncological principles. When the subject are hindfoot tumor lesions, the early diagnosis is extremely important, as well as the proper staging and the management of the case by the orthopedic oncological professional according to oncological principles.
