Introduction:

Tibioperoneal syndesmosis injuries are frequent both in isolation or associated with posterior malleolus fractures. Clinical diagnosis is confirmed on imaging studies. Fixation methods might be rigid or dynamic as well.

Objective:

Provide new aspects related to tibioperoneal syndesmosis injuries in terms of diagnosis, fixation methods and the use of arthroscopic procedure.

Method:

Search and analysis of information needed were carried out in a period of 61 days (from October 1 to November 30, 2022) and the following words were used: syndesmosis injury, ankle syndesmosis instability, syndesmosis instability AND tight rope ankle instability, posterior maleolar fracture. Based on the information obtained, a bibliographic review of the total of 258 articles published in the PubMed, Hinari, SciELO and Medline databases was carried out using the search engine and reference manager EndNote.

Development:

It was expressed in the study aspects related to clinical management used in diagnostic and classification on the types of CT scan for fracture associated with posterior malleolar fracture. The rigid and dynamic fixation methods and its characteristics were mentioned as well. The arthroscopic approaches and its advantages for both diagnosis and treatment were presented.

Conclusions:

Distal tibioperoneal syndesmosis injuries are frequent ankle injury. Tomographic studies offer some advantages for determining how large the posterior malleolus fracture is. The arthroscopic approach offers multiple diagnostic and therapeutic advantages too.
