Abstract:

Objective　To explore the efficacy and safety of the posteromedial anatomical plate (PmAP) on treating the distal tibial fractures.　Methods　The simulated operation of minimally invasive plate osteosynthesis using PmAP was performed on six pairs frozen adult lower extremity specimens through posteromedial approach. The effects on operational field exposing was evaluated. Postoperatively, the relationship among the surgical incision and the GSV, SN was observed. The integrity of both anterior and posterior neurovascular bundles, the contact relation between the PmAP and the neurovascular bundles were focused on.　Results　The operation performed smoothly. Operational field exposing was sufficient. The dissection indicated that, the GSV, SN and surgical incision intersected at the point （7.37±1.65）cm（5.02～8.16 cm） above the medial malleolus, and there was no neurovascular damage, compression or entrapment caused by plates was found, as well, no direct contact between the implant and neurovascular bundle was found.　Conclusions　The study claims that the PmAP was simple and safe, for treating the distal tibial fractures through the posteromedial approach.
