Objective To investigate the clinical effect of reconstructed bone xenograft plus buttress plate (T or L type) fixation in treating tibial plateau fracture. Methods From June 2001 to March 2003, 32 cases of tibial plateau fractures were treated by means of open reduction,reconstructed bone xenograft plus buttress plate (T or L type) fixation. There were 23 cases of bumper fracture, 5 cases of falling injury and 4 cases of crush injury by a weight; 20 males and 12 females, aged from 18 to 69 years with an average of 38 years. All patients had close fracture. Results All the patients were followed upfor 9 months to 23 months, tibial plateau fracture healed satisfactorily without sunken articular surface. According to Pasmussen criterion, the results were excellent in 16 knees, good in 12knees and moderate in 3 knees. The satisfactory rate was 87.5%. Conclusion Reconstructed bone xenograft plus buttress plate internal fixation has good effect in treating tibial plateau fractures because it can avoid the complication of transplantation of ilium.
Objective To investigate the effectiveness of the reverse traction device in the preoperative treatment of high-energy tibial plateau fractures. Methods A retrospective study was conducted to analyze the clinical data of 33 patients with high-energy tibial plateau fractures who met the selection criteria between December 2020 and December 2023. All patients were treated by open reduction and internal fixation. According to the preoperative traction method, they were divided into the observation group (16 cases, treated with a reverse traction device on the day of admission) and the control group (17 cases, treated with heel traction on the day of admission). There was no significant difference in baseline data such as gender, age, body mass index, affected side, cause of injury, fracture Schatzker classification between the two groups (P>0.05). Preoperative waiting time, preoperative related complications (nail channel loosening, nail channel oozing, nail channel infection, soft tissue necrosis, soft tissue infection, deep vein thrombosis of the lower extremity, etc.), operation time, and total hospitalization time were recorded and compared between the two groups. On the 4th day after traction, visual analogue scale (VAS) score was used to evaluate the pain relief of the patients, the swelling value of the affected limb was measured, and the Immobilization Comfort Questionnaire (ICQ) score was used to evaluate the perioperative hospital comfort of the patients. Results Both groups of patients completed the operation successfully, and the operation time, total hospitalization time, and preoperative waiting time of the observation group were significantly less than those of the control group (P<0.05). There was no preoperative related complications in the observation group; in the control group, 3 patients had nail channel loosening and oozing, and 2 cases had the deep vein thrombosis of the lower extremity; the difference in the incidence of complication between the two groups was significant (P<0.05). On the 4th day after traction, the ICQ score, VAS score, and limb swelling value of the observation group were significantly better than those of the control group (P<0.05). X-ray films showed that the tibial plateau fracture separation and lower limb alignment recovered after calcaneal traction in the control group, but not as obvious as in the observation group. The fracture gap in the observation group significantly reduced, the tibial plateau alignment was good, and the lateral angulation deformity was corrected. Conclusion The use of reverse traction treatment in patients with high-energy tibial plateau fractures on admission can accelerate the swelling around the soft tissues to subside, reduce patients’ pain, shorten the preoperative waiting time, improve the patients’ preoperative quality of life, and contribute to the shortening of the operation time, with a good effectiveness.
Objective To compare the effectiveness of arthroscopy assisted percutaneous internal fixation and open reduction and internal fixation for Schatzker types II and III tibial plateau fractures. Methods Between August 2006 and April 2010, 58 patients with tibial plateau fractures of Schatzker types II and III were treated with arthroscopy assisted percutaneous internal fixation (arthroscopy group, n=38), and with open reduction and internal fixation (control group, n=20). There was no significant difference in gender, age, disease duration, fracture type, and compl ication between 2 groups (P gt; 0.05). The operation time, incision length, fracture heal ing time, and compl ications were compared between 2 groups. Knee function score and the range of motion were measured according to American Hospital for Special Surgery (HSS) scorestandard. Results All patients achieved primary incision heal ing. The arthroscopy group had smaller incision length andlonger operation time than the control group, showing significant differences (P lt; 0.05). The patients of 2 groups were followed up 12 to 14 months. At 6 months, the HSS score and the range of motion of the arthroscopy group were significantly greater than those of the control group (P lt; 0.05). The X-ray films showed bony union in 2 groups. The fracture heal ing time of the arthroscopy group was shorter than that of the control group, but no significant difference was found (t=2.14, P=0.41). Morning stiffness occurred in 2 cases (5.3%) of the arthroscopy group, joint pain in 6 cases (30.0%) of the control group (3 cases had joint stiffness) at 1 week, which were cured after symptomatic treatment. There was significant difference in the incidence of compl ications between 2 groups (χ2=6.743, P=0.016). Conclusion The arthroscopy assisted percutaneous internal fixation is better than open reduction and internal fixation in the treatment of tibial plateau fractures of Schatzker types II and III, because it has smaller incision length and shorter fracture heal ing time.
ObjectiveTo evaluate the effectiveness and safty of posterior popliteal fossa S-shaped incision with double-window approach for the treatment of posterior column of tibial plateau fractures.MethodsA retrospective analysis was made on the clinical data of 13 patients with complex tibial plateau fractures involving both posteromedial and posterolateral columns between May 2015 and July 2017. There were 9 males and 4 females, aged 33-64 years (mean, 46.5 years). The causes of injury included traffic accident in 5 cases, falling from height in 2 cases, falling from electric bicycle in 4 cases, and falling because of skiing in 2 cases. The preoperative range of motion of the affected knees was (35.1±9.2)°. The time from injury to surgery was 7-19 days (mean, 13.3 days). All patients underwent a posterior popliteal fossa S-shaped incision through the window of medial heads of gastrocnemius muscle (medial window) and the window between medial and lateral head of gastrocnemius muscle (popliteal fossa window) approaches. After a good visual control of fracture reduction, both posteromedial and posterolateral columns of tibial plateau fractures were fixed with buttress plate respectively. Bone union, limb alignment, articular surface, and range of motion were estimated after operation. The American Hospital for Special Surgery (HSS) score was used to evaluate functional outcomes of knees.ResultsAfter operation, 1 patient had fat liquefaction and dehiscence of incision, which healed after expanding the wound; the other patients’ incisions healed by first intention, and no vascular or nerve injury occurred during operation. All the 13 patients were followed up 12-18 months (mean, 16 months). The X-ray films showed that all patients obtained good fracture unions, the fracture healing time was 14-22 weeks (mean, 18 weeks). At 12 months after operation, the articular surface was smooth without collapse, and the knee range of motion was (109.5±13.6)°, showing significant difference when compared with preoperative value (t=18.879, P=0.000). No complication of infection, re-displacement of fracture, or secondary varus/valgus deformity was observed during follow-up. The HSS score was 82-96 (mean, 89.6) at 12 months after operation, with the result of excellent in 10 cases and good in 3 cases.ConclusionThe posterior column fracture of tibial plateau involving both posteromedial and posterolateral columns treated by double-window approach through posterior popliteal fossa S-shaped incision is safe and effective, with satisfactory results and good recovery of knee joint function.
Objective To compare the effectiveness and advantages of the double reverse traction reduction versus open reduction internal fixation for treating complex tibial plateau fractures. Methods A clinical data of 25 patients with Schatzker type Ⅴ or Ⅵ tibial plateau fractures, who met the selection criteria and were admitted between January 2019 and January 2023, was retrospectively analyzed. Thirteen patients underwent double reverse traction reduction and internal fixation (double reverse traction group), while 12 patients underwent open reduction and internal fixation (traditional open group). There was no significant difference in the baseline data (age, gender, injury mechanism, Schatzker classification, interval between injury and operation) between the two groups (P>0.05). The effectiveness were evaluated and compared between the two groups, included operation time, intraoperative blood loss, incision length, hospital stay, full weight-bearing time, complications, fracture healing, Rasmussen radiological score (reduction quality), knee Hospital for Special Surgery (HSS) score, and knee flexion/extension range of motion. Results The double reverse traction group demonstrated significantly superior outcomes in operation time, intraoperative blood loss, hospital stay, incision length, and time to full weight-bearing (P<0.05). Two patients in traditional open group developed incisional complications, while the double reverse traction group had no complication. There was no significant difference in the incidence of complication between the two groups (P>0.05). All patients were followed up 24-36 months (mean, 30 months), with no significant difference in follow-up duration between groups (P>0.05). Fractures healed in both groups with no significant difference in healing time (P>0.05). At 6 months after operation, Rasmussen radiological scores and grading showed no significant difference between the two groups (P>0.05); the double reverse traction group had significantly higher HSS scores compared to the traditional open group (P<0.05). At 12 months after operation, knee flexion/extension range of motion were significantly greater in the double reverse traction group than in the traditional open group (P<0.05). ConclusionDouble reverse traction reduction offers advantages over traditional open reduction, including shorter operation time, reduced blood loss, minimized soft tissue trauma, and improved joint functional recovery. It is a safe and reliable method for complex tibial plateau fractures.
ObjectiveTo introduce the surgery method to reset and fix tibial plateau fracture without opening joint capsule, and evaluate the safety and effectiveness of this method. MethodsBetween July 2011 and July 2013, 51 patients with tibial plateau fracture accorded with the inclusion criteria were included. All of 51 patients, 17 cases underwent open reduction and internal fixation without opening joint capsule in trial group, and 34 cases underwent traditional surgery method in control group. There was no significant difference in gender, age, cause of injury, time from injury to admission, side of injury, and types of fracture between 2 groups (P>0.05). The operation time, intraoperative blood loss, incision length, incision heal ing, and fracture healing were compared between 2 groups. The tibial-femoral angle and collapse of joint surface were measured on X-ray film. At last follow-up, joint function was evaluated with Hospital for Special Surgery (HSS) knee function scale. ResultsThe intraoperative blood loss in trial group was significantly less than that in control group (P<0.05). The incision length in trial group was significantly shorter than that in control group (P<0.05). Difference was not significant in operation time and the rate of incision heal ing between 2 groups (P>0.05). The patients were followed up 12-30 months (mean, 20.4 months) in trial group and 12-31 months (mean, 18.2 months) in control group. X-ray films indicated that all cases in 2 groups obtained fracture heal ing; there was no significant difference in the fracture healing time between 2 groups (t=1.382, P=0.173). On X-ray films, difference was not significant in tibial-femoral angle and collapse of joint surface between 2 groups (P>0.05). HSS score of the knee in trial group was significantly higher than that of control group (t=3.161, P=0.003). ConclusionIt can reduce the intraoperative blood loss and shorten the incision length to use open reduction and internal fixation without opening joint capsule for tibial plateau fracture. Traction of joint capsule is helpful in the reduction and good recovery of joint surface collapse. In addition, the surgery without opening joint capsule can avoid joint stiffness and obtain better joint function.
ObjectiveTo evaluate the biomechanical effect of a nickel-titanium (Ni-Ti) three-dimensional memory alloy mesh in treating a canine tibial plateau collapse fracture model and to lay a foundation for further experiments in vivo.MethodsSixteen tibial plateau specimens of 8 adult Beagle dogs were harvested. Twelve specimens were taken to prepare canine tibial plateau collapse fracture models (Schatzker type Ⅲ) and randomly divided into groups A, B, and C, with 4 specimens in each group. Four normal tibia specimens were used as blank control group (group D). In groups A and B, the bone defects were repaired with Ni-Ti three-dimensional shape memory alloy mesh combined with autologous bone and simple autologous bone respectively, and fixed with the lateral plate and screw. In group C, the bone defect was directly fixed with the lateral plate and screw. By using a biomechanical tester, a progressive load (0-1 700 N) was loaded vertically above the femoral condyle. The maximum failure load was recorded and the stiffness was calculated according to the load-displacement curve.ResultsThe maximum failure loads in groups A, B, C, and D were (1 624.72±7.02), (1 506.57±3.37), (1 102.00±1.83), and (1 767.64±24.56) N, respectively; and the stiffnesses were (129.72±20.83), (96.54±27.05), (74.96±17.70), and (169.01±35.62) N/mm, respectively. The maximum failure load and stiffness in group A were significantly higher than those in groups B and C, but which were significantly lower than those in group D (P<0.05).ConclusionNi-Ti three-dimensional memory alloy mesh combined with autologous bone can repair the Schatzker type Ⅲ tibial plateau collapse fracture, which has better biomechanical properties than simple autologous bone grafting.
