Minimally invasive treatment of posterolateral tibial plateau fractures with bamboo raft reduction method combined with jail screws: A case report

Introduction and importance

As an intra-articular partial fracture, the posterolateral fracture fragment (PLF) of the tibial plateau has long posed a clinical challenge for orthopedic surgeons. This complexity arises from its unique anatomical characteristics, the risk of associated neurovascular injuries, and the interference caused by the fibular head during the selection of surgical approaches and internal fixation strategies.

Presentation of case

A 35-year-old female was admitted due to pain and restricted mobility in the right knee joint following a car accident. X-ray and CT scans revealed a posterior lateral tibial plateau fracture with articular surface collapse. Closed reduction was performed using the bamboo raft reduction technique, combined with internal fixation employing jail screws. Early postoperative ambulation was achieved. During the follow-up period, no fracture displacement was detected, and imaging confirmed satisfactory bone healing with favorable clinical outcomes. Functional assessment using the Knee Society Clinical Rating System (KSS) yielded a clinical score of 95 and a functional score of 90.

Clinical discussion

This fracture pattern was effectively managed using the bamboo raft reduction technique combined with jail screw fixation. This approach yielded excellent clinical outcomes and high patient satisfaction, with no postoperative complications observed.

Conclusion

The bamboo raft reduction technique combined with jail screw fixation for the treatment of PLF of the tibial plateau has the advantages of small trauma and quick recovery. This fixation method has strong theoretical feasibility and can provide a reference for clinicians.
