Cain ME, et al. - The researchers designed this study to evaluate the incidence of intra-articular screw penetration of the proximal (PTFJ) and distal (DTFJ) tibiofibular joints after interlocking of intramedullary-nails (IMN) for tibial fractures. Findings here indicated a high rate of intra-articular screw penetration of the PTFJ and DTFJ after interlocking of IMN for these fractures. The incidence of TJF violation could be reduced with changes to enable alteration in forced angle of interlocking screw trajectory and avoidance of the anteromedial to posterolateral locking screw.
