Abstract:
Objective To analyze the validity and safety of using a novel posteromedial approach whose L-shaped incision is reversed in treatment of posterior fractures of the tibial plateau. Methotis Anatomical research was performed on 4 fresh-frozen cadaveric specimens with 8 normal knees. All specimens were dissected by the posteromedial reversed L-shaped approach. Parameters of the important structures were measured. Results two important structures were involved in the novel approach. Including medial saral artery and vein and inferior medial genicular artery. The average distance between the eruptive site of medial sural artery and articular surface was 45.29 mm, and the average length ofmedial sural artery was 36.28 mm. The average distance between the eruptive site of inferior medial genicular artery and articular surface was 10.12 mm. The main posterior structures of the proximal tibia were all surveyed by the single approach, including the posterior bi-condyles and the tibial insertion of the posterior crueiate ligament. Conclusion The posteromedial reversed L-shaped approach is an effective approach for treating posterior fractures of the tibial plateau or posterior injuries of the proximal tibia, because it is less invasive, highly safe, simple in anatomy, direct and sufficient in exposure.
