LOCALIZATION OF THE TIBIAL ENTRY POINT.

Objective: To assess the intramedullary nail entry point in the proximal region of the tibia, through a questionnaire.

Methods: 230 participants undergoing treatment for tibial fractures were interviewed. The questionnaire was created with three sections that could be answered in a "Yes" or "No" format and a fourth section that had two figures representing anteroposterior (AP) and lateral view x-rays that could be answered in an "A, "B" or "C" format.

Results: The most frequent reason was "ease of access" (67.8%), followed by "better nail insertion access" (60.9%) and, in third place, "to prevent knee pain" (27.4%). The reasons for choosing the access so as to "prevent knee pain" and "avoid tendinitis" had a significant relationship with points "A" and "C" of the schematic AP x-ray figure, especially "C" (medial tibial crest). There were no significant differences between the types of access to the patellar ligament in the schematic AP and lateral x-ray figures between age groups.

Conclusion: The greater the age was, the larger the proportion choosing the question "to avoid valgus deformity" was. The reasons from a medical (practical) perspective related to the type of access in the transpatellar ligament, while the reasons from a patient (functional) perspective related to medial parapatellar access. Transpatellar access was chosen by most of the participants (66.5%).
