| Objective To investigate the application and clinical effect of superior peroneal approach combined with annular plate in the treatment of posterolateral condylar fracture of tibial plateau.Methods The clinical data of 19 cases of lateral tibial plateau fractures involving the posterolateral condyle treated in Kunshan Hospital of Traditional Chinese Medicine Affiliated to Nanjing University of Traditional Chinese Medicine from January 2019 to June 2021 were retrospectively analyzed. There were 11 males and 8 females, aged from 32 to 65 years, with an average of 46.3 years. According to the four-column theory, there were 6 cases of simple posterolateral column fracture and 13 cases of posterolateral combined anterolateral column fracture. The supra-fibular-head approach was used to reduce the fracture, fill the collapsed area with artificial bone, cut off one arm with 3.5mm posterior malleolus T-shaped locking plate, bend it into ring shape to wrap around the edge of the lateral platform, and fix it with raft screws. The patients were followed up regularly after operation. The reduction quality was evaluated according to Rasmussen radiation score, and the knee function was evaluated according to HSS score.Results All patients were followed up for 10-24 months, with an average of 14.8 months. The operation time was (83.7±14.1) min, the fracture healing time was (15.7±3.4) weeks, and the complete weight-bearing time was (19.3±2.5) weeks. At the last follow-up, the average range of motion of the knee was (118.6±15.2)°. Rasmussen radiation score: Excellent in 10 cases, good in 8 cases and fair in 1 case, with an excellent and good rate of 94.7%. HSS score of knee function: excellent in 12 cases, good in 5 cases and fair in 2 cases. The excellent and good rate was 89.5%.Conclusion The treatment of posterolateral tibial plateau fractures by superior peroneal approach is simple and safe, combined with reliable internal fixation with annular plate. The short-term clinical effect is satisfactory. |
