Utilization of cannulated screw fixation of Jail and TiRobot-assisted percutaneous indirect reduction technique for AO/OTA type 41B2 tibial plateau fracture treatment.
Knee 2024 January 10
PURPOSE: The present study was designed to investigate the precise procedure and effectiveness of percutaneous minimally invasive fixation assisted by TiRobot in managing AO/OTA type 41B2 tibial plateau fracture to provide an alternative solution for clinical application.
METHODS: In total, 10 participants with AO/OTA type 41B2 tibial plateau fractures diagnosed by preoperative imaging examinations were enrolled in this study between May 2019 and May 2022. They were 5 males and 5 females, with an average age of 45.6 ± 11.3 years old (range 27-62 years old). All of them had closed fractures, including 6 cases with anterior cruciate ligament (ACL) tibial insertion avulsion fractures, 1 case with medial collateral ligament (MCL) tear, and 4 cases with a lateral meniscus tear. From injury through surgery, the entire time frame was 4.0 ± 1.5 days (range, 2-7 days). Following indirect percutaneous reduction assisted by TiRobot, the Jail method was used to treat all patients with minimally invasive internal fixation. Patients with ligament or meniscus injurieswere treated with arthroscopic surgery in one stage. The standardized functional exercise was performed postoperatively. The knee function was measured using the Hospital for Special Surgery (HSS) score, and the fracture reduction was assessed through the Rasmussen radiology score.
RESULTS: All patients were followed up for 12.7 ± 6.8 months (6-24 months).The fracture healing time was 11.8 ± 0.8 weeks (10-13 weeks), and the X-rays revealed satisfactory fracture reduction.The knee joint's Rasmussen score was 17.8 ± 0.4 (in the range of 17-18) a year after the procedure, with 8 patients receiving outstanding ratings and 2 cases receiving satisfactory scores. The HSS score was 93.8 ± 2.3 (range, 89 to 96), of which 10 cases were excellent. The motion range of the kneewas 138.7°±2.7° (range, -5° to 0° to 135°). No adverse effects or serious complications, such as internal fixation failure, postoperative infection, popliteal vascular injury, and common peroneal nerve injury, were observed during the last follow-up visit.
CONCLUSIONS: The intelligent assistance and accurate guidance of TiRobot can simplify and standardize procedures of percutaneous minimally invasive fixation in theSchatzker type Ⅲ tibial plateau fracture treatment. This technique increases the precision of indirect percutaneous reduction and screw fixation while minimizing bone grafting.
