[PMID: 37287007 DOI: 10.1186/s13018-023-03887-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Accepted: 05/28/2023] [Indexed: 06/09/2023] Open
Abstract
PURPOSE The objective of this study was to investigate the effect of proximal fibular and/or posterolateral joint facet (PJF) fractures on early functional recovery after Schatzker type VI tibial plateau fractures (TPFs). METHODS Seventy-nine patients with Schatzker type VI TPFs sustained from November 2016 to February 2021 were divided into three groups according to the integrity of the proximal fibula and PJF (groups A, B, and C). Details including demographics, duration of surgery, and complications were recorded. The Western Ontario and McMaster Universities Osteoarthritis index (WOMAC) score, Hospital for Special Surgery (HSS) score, lateral knee pain and lateral hamstring tightness were ascertained at the final follow-up. The HSS and WOMAC scores have high reliability in evaluating knee function and osteoarthritis. RESULTS There was a significant difference in the HSS score between groups A and C (P < 0.001) and between groups B and C (P = 0.036). The hospital stay was significantly different between groups A and C (P = 0.038) and between groups B and C (P = 0.013). There was a significant difference in lateral knee pain and lateral hamstring tightness between groups A and C (P < 0.001) and between groups B and C (P < 0.001). CONCLUSION Our study demonstrates that proximal fibular and PJF fractures do not increase the time from injury to surgery, the incidence of complications, or the duration of surgery for Schatzker type VI TPFs. However, fractures of the proximal fibula significantly increase the hospital stay, reduce knee function, and cause lateral knee pain and lateral hamstring tightness. Combined proximal fibular fracture is more decisive than PJF involvement for prognosis.

Lateral locking plate plus antero-posterior lag screws techniques for the management of posterolateral tibial plateau fracture: preliminary clinical results and biomechanical study. Arch Orthop Trauma Surg 2022; 143:3163-3172. [PMID: 35907003 DOI: 10.1007/s00402-022-04554-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 07/15/2022] [Indexed: 11/02/2022]
Abstract
INTRODUCTION To date, there is no consensus on the optimal surgical strategy for the treatment of posterolateral tibial plateau fracture (PLF). This study introduced a novel, simple technique for treating PLF with a lateral locking plate plus antero-posterior lag screws (LPpLS). METHODS We conducted a retrospective case series of 42 patients (Female/Male 19/23) with PLF treated with LPpLS between 1 July 2016 and 30 June 2019. Several pre- and postoperative outcomes were recorded, including operative time, intraoperative blood loss, CT findings, HSS, and ROM. For biomechanical studies, seventy synthetic tibiae with a simulated posterolateral split fracture were divided into seven groups. The biomechanical evaluation included displacement measurement at axial compression and fatigue testing. RESULTS Forty-two eligible patients were followed up for an average of 18 months (range 14-21 months). Postoperative radiographs and CT showed good positioning of plates and screws, no fracture fragment loss, and normal articular surfaces in all 42 cases. The biomechanical study showed that the axial stiffness of LPpLS was in the same fashion as the posterior buttress plate and better than the other fixation methods (P < 0.05). Additionally, the LPpLS group had a smaller displacement of fracture fragments along the X-axis (medial to lateral direction) than the BP group (P < 0.01). CONCLUSIONS The LPpLS technique could implement good reconstruction of the PLF, showing satisfactory therapeutic effect. The biomechanical evaluation demonstrated that the LPpLS had better stability in three-dimensional directions for PLF than other fixation strategies.

Comparison of the Effects of Intramedullary Nailing and Plate Fixation on Lower-Extremity Deep Vein Thrombosis after Tibial Fractures. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:4852201. [PMID: 35401776 PMCID: PMC8993547 DOI: 10.1155/2022/4852201] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/26/2021] [Revised: 12/27/2021] [Accepted: 12/31/2021] [Indexed: 11/18/2022]
Abstract
Lower-extremity deep vein thrombosis (DVT) is prone to occur after internal fixation of tibial fractures. This study analyzed the effect of intramedullary nailing (IMN) and plate fixation (PF) on lower-extremity DVT, providing reliable reference and guidance for future clinical treatment of tibial fractures. Sixty-eight patients with tibial fractures admitted to Honghui Hospital, Xi’an Jiaotong University, between February 2019 and October 2020 were selected as research participants, of which 32 cases treated with open reduction and locking-compression plate fixation were assigned to the FP group and 36 cases treated with closed reduction and interlocking IMN were included in the FN group. The two groups were compared regarding the following items: clinical efficacy, operation, rehabilitation, joint function, pain, inflammatory factors (IFs), incidence of adverse reactions (ARs), blood loss, prognosis, and quality of life (QoL). The related factors affecting the occurrence of DVT were analyzed. The results identified no evident difference in the overall response rate between the two groups (
). The FN group showed longer operation time, higher incidence of ARs, and better rehabilitation, while there were lower incision length, VAS score, and IF levels (
). The results revealed no significant difference in estnimated blood volume(EBV) and the incidence of DVT between the two groups(
); however, the total blood loss (TBL), hidden blood loss (HBL), and blood transfusion rates in FN group were higher while the visible blood loss (VBL) was lower compared to the FP group (
). Logistic regression analysis identified that blood transfusion, VBL, HBL, TBL, and treatment methods were independent risk factors affecting the occurrence of lower-extremity DVT (
). In addition, the prognostic QoL was better in the FN group (
). Therefore, closed reduction and interlocking IMN are more effective than open reduction and locking-compression plate fixation in the treatment of tibial fractures, but patients are more likely to suffer from lower-extremity DVT. In the future, it is necessary to carefully choose the treatment method in the treatment of tibial fracture patients to ensure their rehabilitation.

A Case Study Focusing on Tibial Plateau Fracture. Front Bioeng Biotechnol 2021; 9:722275. [PMID: 34692655 PMCID: PMC8529153 DOI: 10.3389/fbioe.2021.722275] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Accepted: 09/06/2021] [Indexed: 11/20/2022] Open
Abstract
Background and context: Surgical procedures are evolving toward less invasive and more tailored approaches to consider the specific pathology, morphology, and life habits of a patient. However, these new surgical methods require thorough preoperative planning and an advanced understanding of biomechanical behaviors. In this sense, patient-specific modeling is developing in the form of digital twins to help personalized clinical decision-making. Purpose: This study presents a patient-specific finite element model approach, focusing on tibial plateau fractures, to enhance biomechanical knowledge to optimize surgical trauma procedures and improve decision-making in postoperative management. Study design: This is a level 5 study. Methods: We used a postoperative 3D X-ray image of a patient who suffered from depression and separation of the lateral tibial plateau. The surgeon stabilized the fracture with polymethyl methacrylate cement injection and bi-cortical screw osteosynthesis. A digital twin of the patient’s fracture was created by segmentation. From the digital twin, four stabilization methods were modeled including two screw lengths, whether or not, to inject PMMA cement. The four stabilization methods were associated with three bone healing conditions resulting in twelve scenarios. Mechanical strength, stress distribution, interfragmentary strains, and fragment kinematics were assessed by applying the maximum load during gait. Repeated fracture risks were evaluated regarding to the volume of bone with stress above the local yield strength and regarding to the interfragmentary strains. Results: Stress distribution analysis highlighted the mechanical contribution of cement injection and the favorable mechanical response of uni-cortical screw compared to bi-cortical screw. Evaluation of repeated fracture risks for this clinical case showed fracture instability for two of the twelve simulated scenarios. Conclusion: This study presents a patient-specific finite element modeling workflow to assess the biomechanical behaviors associated with different stabilization methods of tibial plateau fractures. Strength and interfragmentary strains were evaluated to quantify the mechanical effects of surgical procedures. We evaluate repeated fracture risks and provide data for postoperative management.

The degree of fracture displacement does not affect the risk for concomitant proximal fibular fractures in tibial plateau fractures. INTERNATIONAL ORTHOPAEDICS 2021; 45:2963-2971. [PMID: 33825001 DOI: 10.1007/s00264-021-05034-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/30/2020] [Accepted: 03/29/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVE The proximal fibula plays an important role in the knee joint; however, it has not been given enough attention by surgeons. This study aimed to investigate the risk factors for concomitant proximal fibular fractures in patients with tibial plateau fractures through computed tomography (CT) imaging. MATERIALS AND METHODS From January 2016 to November 2017, patients who underwent percutaneous reduction and internal fixation (PRIF) for tibial plateau fractures at a level 1 trauma centre institute were included in this retrospective study. Full materials of CT imaging were obtained for measurements. Schatzker's and a newly proposed classification system were used for the fracture of the tibial plateau and proximal fibula, respectively. Several clinical and radiological characteristics were recorded, and the impact of those variables on fibular fractures was assessed with univariate and multivariate analyses. RESULTS In total, 174 patients were enrolled in the study with mean age of 45.6±13.1 years. The incidence of combined proximal fibular fracture was 38.3%. Schatzker type VI fracture had the highest rate of fibular fracture (77.4%). High-energy-pattern tibial plateau fractures (p=0.029) and posterolateral joint facet (PJF) involvements (p=0.002) are risk factors for proximal fibular fracture on multivariate analysis. Neither posterolateral column (PLC) involvements nor fracture displacement correlated with proximal fibular fractures. CONCLUSIONS Proximal fibular fractures were commonly seen among patients who sustained tibial plateau fractures. Schatzker type VI fractures had the highest rate of fibular fractures than other fracture types. High-energy fractures and PJF involvements correlated with a higher risk of proximal fibular fractures. A better understanding and awareness of the risk factors for proximal fibular fractures will provide surgeons with comprehensive understanding of tibial plateau fractures.

Abstract
Understanding the structural response of bone during locomotion may help understand the etiology of stress fracture. This can be done in a subject-specific manner using finite element (FE) modeling, but care is needed to ensure that modeling assumptions reflect the in vivo environment. Here, we explored the influence of loading and boundary conditions (BC), and compared predictions to previous in vivo measurements. Data were collected from a female participant who walked/ran on an instrumented treadmill while motion data were captured. Inverse dynamics of the leg (foot, shank, and thigh segments) was combined with a musculoskeletal (MSK) model to estimate muscle and joint contact forces. These forces were applied to an FE model of the tibia, generated from computed tomography (CT). Eight conditions varying loading/BCs were investigated. We found that modeling the fibula was necessary to predict realistic tibia bending. Applying joint moments from the MSK model to the FE model was also needed to predict torsional deformation. During walking, the most complex model predicted deformation of 0.5 deg posterior, 0.8 deg medial, and 1.4 deg internal rotation, comparable to in vivo measurements of 0.5-1 deg, 0.15-0.7 deg, and 0.75-2.2 deg, respectively. During running, predicted deformations of 0.3 deg posterior, 0.3 deg medial, and 0.5 deg internal rotation somewhat underestimated in vivo measures of 0.85-1.9 deg, 0.3-0.9 deg, 0.65-1.72 deg, respectively. Overall, these models may be sufficiently realistic to be used in future investigations of tibial stress fracture.

Abstract
OBJECTIVE To summarize the indications and the clinical effects of a transfibular neck osteotomy approach and a combined anterolateral and posterolateral approach in the treatment of fractures of the lateral tibial plateau involving the posterolateral column. METHODS Eleven patients with lateral tibial plateau fractures were included in the present study. The fractures were Schatzker type II or lateral platform fractures involving posterolateral column. The anterolateral combined posterolateral approach (lateral + posterolateral locking plate fixation) was applied in 7 patients and 4 patients underwent transfibular neck osteotomy (lateral + posterolateral locking plate fixation + 1/4 tubular plate edge fixation, fibular osteotomy with Kirschner wire tension band fixation, and hollow nail fixation for upper tibiofibular joint). All cases were followed up for 12-24 months, with an average follow-up of 17.5 ± 5.0 months. At the last followup, the Rasmussen radiological criteria were used to evaluate the effect of fracture reduction and fixation. The knee joint function was evaluated using the knee function evaluation criteria of the Hospital for Special Surgery (HSS). The Lachman test and the pivot-shift test were used to evaluate the anterior and posterior and rotational stability of the knee joint. The range of knee motion was recorded. RESULTS Bone healing was achieved in all patients with fractures treated with a transfibular neck osteotomy approach and a combined anterolateral and posterolateral approach. At the last follow-up, both the Lachman test and the pivot-shift test results were negative. All patients had complete knee extension. For the combined anterolateral and posterolateral approach, the knee flexion angle was 110°-130°, with an average of 122.86° ± 7.56°. For the transfibular neck osteotomy approach, the knee flexion angle was 115°-130°, with an average of 120.00° ± 7.07°. For the patients in which the combined anterolateral and posterolateral approach was used, the Rasmussen score was 12-18 points, with an average of 16.00 ± 2.56 points. The results were excellent in 4 cases and good in 3 cases; therefore, 100% of results were excellent or good. For patients in which the transfibular neck osteotomy approach was used, the Rasmussen score was 10-18 points, with an average of 15.25 ± 3.77 points. The results were excellent in 2 cases, good in 1 case, and acceptable in 1 case; therefore, 75% of results were excellent or good. The HSS score for the combined anterolateral and posterolateral approach was 76-98 points, with an average of 88.43 ± 7.55 points. The results were excellent in 5 cases and good in 2 cases; therefore, 100% of results were excellent or good. The HSS score for the transfibular neck osteotomy approach was 74-96 points, with an average of 87.25 ± 9.43 points. The results were excellent in 3 cases and good in 1 case; therefore, 100% of results were excellent or good. There were no significant differences in operation time, surgical blood loss, fracture healing time, postoperative imaging score, and knee function evaluation between the two approaches. One patient who underwent transfibular neck osteotomy had a 3-mm step that gradually appeared, but no significant abnormalities were found in the width of the platform and the lower limb force line. One patient in whom the combined anterolateral and posterolateral approach was used showed numbness in the common peroneal nerve. No common peroneal nerve injury occurred through the transfibular neck osteotomy approach. CONCLUSIONS The anterolateral combined posterolateral approach and the transfibular neck osteotomy approach are effective in the surgical treatment of lateral tibial plateau fractures involving the posterolateral column. However, the transfibular neck osteotomy approach is more suitable for the posterolateral plateau articular surface damaged with bone separation and displacement, deep collapse, cases involving a large range of the posterolateral column, especially fractures of the lateral tibial plateau in the upper tibiofibular syndesmosis area of the line connecting the anterior and posterior margin of the fibular head to the midpoint of the plateau.
