ABSTRACT

Objective:To explore the morphological characteristics, treatment strategies and clinical results of complex hyperextension tibial plateau fractures.Methods:From October 2017 to January 2019, data of 27 patients with complex hyperextension tibial plateau fractures were retrospectively analyzed. There were 19 males and 8 females with an average age of 43.4 years (range, 23-68 years). According to Schatzker classification of tibial plateau fractures: there are 8 cases of type IV, 5 of type V, and 14 of type VI; according to the three-column theory classification: there are 8 cases of two-column fracture and 19 cases of three-column fracture. Bicondylar fractures were treated with medial Tomofix locking plate and anterolateral L-shaped locking plate through medial and anterolateral approach; tibialmedial condylar fractures was treated with T-shaped plate and posteromedial locking plate through extended medial approach. Patients with anterior tibial fractures were treated with horizontal strip plate through modified anterior median approach. Combined soft tissue or bone injury was repaired. The fracture healing and reduction were evaluated by X-ray and CT scan. The reduction of tibial plateau fracture was evaluated by Rasmussen radiology standard, and the knee joint function was evaluated 12 months after the operation by the score of American hospital for special surgery (HSS).Results:All the 27 surgeries were performedsuccessfully. The operation time was 130-350 minutes, with an average time of 165 minutes. Twenty-seven cases were followed up for 12-24 months, with an average period of 15.8 months. All fractures were healed. The average clinical healing time was 13.5 weeks (range, 10-18 weeks). Twelve months after operation, Rasmussen's radiology score was 13-18, with an average of 16.7 points, among them there were 19 excellent and 8 good. Twelve months after the operation, the score of HSS knee joint was 82-98, with an average score of 93.2 points, and there were 22 cases excellent, 4 cases good and 1 case fair. The excellent and good rate was 96.2% (26/27).Conclusion:Complex hyperextension tibial plateau fractures often combined with tibial bicondylar, medial tibial condyle or anterior tibial fractures. According to the morphological characteristics of complex hyperextension tibial plateau fractures, using appropriate surgical approach and internal fixation, repairing ligament soft tissue structure and reconstructing knee joint stability can achieve satisfactory results.

ABSTRACT

Objective:To discuss how to make the surgical strategy for tibial tubercle fracture associated with bicondylar tibial plateau fracture.Methods:Data of thirty-five patients of tibial tubercle fractures associated with bicondylar tibial plateau fractures who were treated from October 2014 to May 2018 were retrospectively analyzed. There were 26 males and 9 females with an average age of 37.6 years (range, 21-68 years). According to Schatzker classification in tibial plateau fracture, 16 cases were type V and 19 cases were type VI. According to the integrity of tibial tubercle fracture and cortical bone of the proximal tibia in bicondylar tibial plateau fracture, they were divided into four types: type A, tibial tubercle fracture fragment and cortical bone of the proximal tibia are both complete; type B, tibial tubercle fracture fragment is complete but cortical bone of the proximal tibia is comminuted; type C, tibial tubercle fracture fragment is comminuted but cortical bone of the proximal tibia is complete; type D, both of them are comminuted. The surgical approaches and fixation methods of all the tibial tubercle fractures were according to the four different types. There were 22 cases with type A and B that were treated via an anterolateral and a medial incision, 13 cases with type C and D were treated via an anterior midline and a medial incision. There were 4 cases belonging to type A fixed with lag screws singly, 18 cases with type B fixed with 1/4 tubular plates, 7 cases with type C and 6 cases with type D fixed by 1/4 tubular plates combined with lag screws.Results:Thirty-five patients were followed up for 16.8 months (range, 12-24 months). All fractures healed with an average time of 4.7 months (range, 3-6 months). Loss of reduction didn’t occur in 34 cases except one. According to Rasmussen radiographic evaluation, the average score was 14.1 (range, 10-18) and clinical outcomes were rated with excellent in 11 cases, good in 19, fair in 5. The excellent and good rate was 85.7% (30/35) . The mean Hospital for Special Surgery (HSS) scores of all cases were 86.8 (range, 64-98) and the functional scores were excellent in 22 cases, good in 10 cases and fair in 3 cases with the excellent and good rate of 91.4% (32/35) . Surgical complications included fat liquefaction in 2 cases, superficial wound infection in 1, loosening of implant in 1and traumatic arthritis in 1.Conclusion:This kind of tibial tubercle fracture associated with bicondylar tibial plateau fracture is rare and special. Therefore, the preoperative plan should be made by considering the morphological features of the tibial tubercle fragments and the cortical bone of the proximal tibia. The middle longitude approach is the best way to expose tibial tubercle fragments which should be fixed with 1/4 tubularplate and/or lag screws.

ABSTRACT

Objective@#To explore the clinical features and treatment strategies of tibial plateau fractures sustained with hyperextension varus.@*Methods@#Data of 11 patients of tibial plateau fractures with hyperextension varus treated from January 2008 to November 2017 were retrospectively analyzed. There were 7 males and 4 females with an average age of 41.2 years old (range, 25-67 years). Injuries were caused by falling down in 7 cases, traffic accident in 3 cases, and falling from height in 1 case, respectively. On the basis of Luo's three columns classification in tibial plateau, there were 9 cases of medial column fracture and 2 cases of medial combined with posterior column fracture. Six cases were concomitant with fibular head fracture and 2 cases with the injury of common peroneal nerve. Preoperative magnetic resonance imaging showed that there were anterior cruciate ligament injury in 3 cases, posterior cruciate ligament injury in 4 cases, medial meniscus injury in 5 cases, lateral meniscus injury in 3 cases, medial collateral ligament injury in 6 cases, iliotibial band injury in 2 cases and posterolateral complex injury of the knee joint in 9 cases, respectively. All tibial plateau fractures were treated firstly by open reduction and internal fixation via medial approach of the knee. The medial meniscuses and collateral ligaments were explored, in which of them there were 2 medial meniscuses with the marginal tear been sutured simultaneously. Then the knee joints which were still unstable after the examination of stable tests in 6 cases with posterolateral complex injuries were repaired surgically via lateral approach. Fibular head fractures were fixed with anchor nails or cannulated screws in 6 cases. The ruptured posterior cruciate ligaments in 2 cases were reconstructed with autologous tendon transplantation under endoscopy.@*Results@#All the patients were followed up for an average period of 16.2 months (range, 12-22 months). All fractures were healed in 10-20 weeks with an average time of 16.5 weeks. The range of extension of the affected knee joint in all patients was 0° and the average flexion was 135° (range, 120°-145°) one year after surgery. The average flexion of affected knee in 4 cases which were only treated with the tibial plateau fracture without the mild ligament injuries was 137° (range, 132°-145°) and the average flexion of affected knee in 7 cases who were treated with tibial plateau fracture and severe posterolateral complex included posterior cruciate ligaments completely broken with reconstruction was 132° (range, 120°-140°). According to Rasmussen radiographic evaluation, the average score of all patients was 16.3 (range, 14 to 18) and clinical outcomes were rated with excellent in 10 cases and good in 1. The excellent and good rate was 100% (11/11). The mean of the hospital for special surgery (HSS) score was 86.7 (range, 79-96) and the functional scores were excellent in 9 cases, good in 2 cases thus the excellent and good rate was 100% (11/11). Both varus stress test 30° and dial test were positive in one case considered for the ligament laxity postoperatively who didn’t accept further treatment and the stabilization tests were negative in the other 10 cases. There were no intraoperative complications in all patients such as neurovascular injury. No incision infection, failure of the implants and fracture nonunion occurred postoperatively. Traumatic arthritis of the affected knee occurred one year after surgery in 1 case who had no obvious pain after treated with oral medicine.@*Conclusion@#The hyperextension varus injuries of the knee are rare clinically. The posterolateral complex should be evaluated thoroughly for this injury pattern. If it's necessary, the posterolateral structures must be repaired surgically after the tibial plateau fractures are fixed.
