A newly designed anatomical plate for the therapy of posterolateral tibial plateau fracture via a supra-fibular-head approach: a retrospective study. Sci Rep 2024; 14:11722. [PMID: 38778129 PMCID: PMC11111735 DOI: 10.1038/s41598-024-62227-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2024] [Accepted: 05/15/2024] [Indexed: 05/25/2024] Open
Abstract
The posterolateral tibial plateau fracture is a special type of intra-articular fracture, for which there is no simple, safe, and effective standardized procedure. In this paper, we evaluate the clinical efficacy and the advantages of the treatment of posterolateral tibial plateau fracture by using our designed proximal lateral tibial rim plate for the posterolateral condyle of the tibial plateau via the space above the fibula head. Thirty-eight patients with posterolateral tibial plateau fractures from June 2018 to June 2021 were retrospectively analyzed. CT scans were used to classify the degree of injury in the included patients. All of them were fixed with reduction using an approach above the fibula head combined with a homemade anatomical plate. The regular postoperative review was performed to instruct functional knee exercises. Postoperative complications were observed and follow-up visits were performed to assess the functional outcome. A total of 38 patients with posterolateral tibial plateau fractures, 13 males and 25 females were included in the study. All patients were followed up for 13-26 months, with a mean of 15.3 months. There were no postoperative complications such as numbness of the limb, knee joint instability, etc. X-ray review showed that the fractures were all healed, and the healing time was 10-16 weeks, with an average of 12.1 weeks; none of the internal fixation loosening and loss of articular surface occurred during the follow-up period. At the last follow-up, according to the HSS knee function score criteria, the scores were 79-98, with an average of 91.3. The HSS score presented excellent in 34 cases (89%) and good in 4 cases (11%). The Rasmussen score was graded as excellent in 29 cases (76%) and good in 9 cases (24%). In conclusion, The treatment of posterolateral tibial plateau fractures by an approach above the fibula head has the advantages of simplicity and safety, small trauma, and no risk of vascular and nerve injuries, and the anatomical proximal lateral tibial rim plate can play a direct and effective supporting role for the bone fragments of the posterolateral condyle, and the combination of both of them has obvious advantages in the treatment of posterolateral condylar fracture of the tibial plateau, and it is a method worth borrowing and popularizing.

Sci Rep 2023; 13:22026. [PMID: 38087037 PMCID: PMC10716110 DOI: 10.1038/s41598-023-49624-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Accepted: 12/10/2023] [Indexed: 12/18/2023] Open
Abstract
Posterolateral (PL)-depression fractures of the tibial plateau are difficult to manage. The aim of this study was: (1) to present our experience with a novel technique of robot-assisted percutaneous reduction and fixation and (2) to compare it with the traditional percutaneous screw osteosynthesis (PSO) technique for the treatment of PL-depression tibial plateau fractures. The clinical data of patients with PL-depression tibial plateau fractures treated by robot-assisted percutaneous reduction and fixation technique and traditional PSO technique from January 2017 to January 2021 were retrospectively analyzed. Among them, there were 18 cases in the robot-assisted group (RA group) and 23 cases in the PSO group. All fractures were unilateral, closed and fresh PL-depression fractures of the tibial plateau. Patients in the RA group were treated by robot assisted reduction and minimally invasive absorbable screw fixation. The PSO group was treated by closed reduction and percutaneous absorbable screw osteosynthesis. The incision length, operation time, intraoperative blood loss, fluoroscopic times, inpatient time, weight training time and postoperative complications of the two groups were statistically analyzed. The Rasmussen radiological score was used to assess the reduction quality after operation while the Rasmussen functional score was used to evaluate knee joint functions at one year postoperatively. All patients were followed for at least one year. There was no significant difference in demographic information between the two groups (p > 0.05). Compared with the PSO group, the RA group showed less fluoroscopic times and better Rasmussen radiological and functional scores (p < 0.05). Besides, there was no significant difference in the incidence of postoperative complications between the two groups (p > 0.05). The novel robot-assisted percutaneous reduction and fixation technique had the characteristics of less radiation, accurate reduction and fixation. It could accelerate the rehabilitation of patients with PL-depression fractures of the tibial plateau and enable patients to obtain good joint functions.

Biomechanical study of a new rim plate fixation strategy for two kinds of posterolateral depression patterns of tibial plateau fractures: a finite element analysis. J Orthop Surg Res 2023; 18:840. [PMID: 37932801 PMCID: PMC10629018 DOI: 10.1186/s13018-023-04315-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 10/24/2023] [Indexed: 11/08/2023] Open
Abstract
PURPOSE The biomechanical capacity of "Barrel Hoop Plate (BHP)" in the treatment of the posterolateral tibial plateau (PL) depression fractures remains unknown. In this study, two kinds of posterolateral tibial plateau depression models involving mild slope-type depression fracture (MSDF) and local sink hole-type depression fracture (LSDF) were created to test and compare the biomechanical capacities of BHP with the other two conventional fixations (Anterolateral Plate and Posterolateral Plate, ALP and PLP) by finite element analysis. METHODS The 3D models of three kinds of plate-screw systems and the two kinds of PL-depression models (MSDF and LSDF) were created. An axial force of 400N was applied from the distal femur to the tibial plateau. The maximal displacements of the posterolateral fractures (PLFs), the distribution on the PLFs articular surface and key points displacements were measured. Stresses in the fixation complex including the maximal Equivalent (von-Mises) Stress of implants, the max shear stress of PLFs and stiffness of the fixation were calculated. RESULTS The maximal displacement of MSDF was least in Group BHP. The maximal displacement of LSDF was least in Group ALP. In MSDF, BHP showed the best rim fix effect in MSDF, but unsatisfactory results in LSDF. In both MSDF and LSDF, the greatest max Equivalent Stress of the plate and the screw occurred in the PLP system. ALP and BHP showed a comparable stiffness in MSDF and ALP had the strongest stiffness in the fixation of LSDF. CONCLUSIONS In MSDF, the BHP has the best biomechanical capacity, especially in displacements of key points such as the PL rim, fracture line, and depression center. In LSDF, the ALP system shows the best biomechanical effect. Although the PLP has the best fixation effect on the posterior wall, it is not suitable for PL-depression fracture fixation.

Abstract
There is no consensus about the optimal internal fixation selection for treatment of posterolateral tibial plateau fracture. This study described a novel plate through an anterolateral approach for posterolateral tibial plateau fractures (PTPFs). We evaluated the biomechanical performance of a novel plate and two conventional internal implants and investigated the anatomic feasibility of the novel plate. The fracture models were randomly assigned into six groups: Groups A–C were the model groups of posterolateral split fracture, fixed with the posterior buttress plate, the lateral locking plate, and the novel plate, respectively. Groups D–E were the model groups of posterolateral depression fracture, fixed with the posterior buttress plate, the lateral locking plate, and the novel plate, respectively. We evaluated the biomechanical performance of six model groups by the biomechanical testing and finite element analysis. Progressively increasing axial compressive loads were applied to each synthetic fracture model by using a customized indentor under 250–750 N loads. Meanwhile, we dissected 12 fresh frozen knee specimens and fixed them with the novel plate through the anterolateral approach. We recorded the adjacency of the novel plate to important anatomic structures. Biomechanical testing showed that the novel plate had the least displacement, followed by the posterior buttress plate, and the lateral plate had the most displacement in posterolateral split fracture. There was no significant difference in the displacement between the novel plate and the lateral plate at different loads in posterolateral depression fractures. And the posterior buttress plate showed the most displacement. In the finite element analysis, the maximum stress values of Groups A, B, and C were 383.76, 414.63, and 305.07 MPa under the load of 750 N, respectively. The maximum stress values of Groups D, E, and F were 474.28, 436.31, and 413.4 MPa under the load of 750 N, respectively. In the anatomic study, the placement of the novel plate had a low risk of damage to the important anatomic structures of knee posterolateral corner. The novel plate could be a great choice for the treatment of PTPFs due to better biomechanical performance and easy manipulation.

Abstract
Objectives To propose an updated definition of proximal tibia and fibula fracture (PTFF) and establish a three‐dimensional (3D) structure‐based classification of PTFF. Methods In total, 1358 adult patients (837 males and 521 females; 43.61 ± 15.13 years, 1364 affected knees) who were diagnosed with PTFF at the departments of orthopaedic surgery of four hospitals from January 2010 to December 2019 were enrolled. The new classification of PTFF, termed Wu classification, included three parts: classification of columns in the horizontal plane, regions in the frontal plane, and segments in the sagittal plane. All PTFFs were classified according to Schatzker, Luo, and Wu classification systems. Additionally, the incidence and characteristics of PTFFs were analyzed. Results The major internal structural fractures of PTFF were tibial plateau fracture (TPF) only (725, 53.15%), TPF and proximal fibular fracture (274, 20.09%), and isolated avulsion fracture of the posterior cruciate ligament (PCL) (189, 13.86%). Approximately a quarter of PTFF cases could not be classified using Schatzker or Luo classifications, but all PTFF cases could be classified using Wu classification. The most frequent PTFFs included all four columns in region IV, segment 2 (235, 17.23%); the posterolateral and posteromedial columns in region II, segment 2 (191, 14.00%); and the lateral and posterolateral columns in region IV, segment 2 (136, 9.97%). Isolated avulsion fracture of the anterior cruciate ligament (ACL) was categorized as three injury types, most of which involved the lateral and medial columns in region II, segment 1 (40/63, 64%). More than 97% of cases of isolated fractures of the PCL involved the posterolateral and posteromedial columns in region II, segment 2. The most frequent combined avulsion fracture of the ACL and PCL included all four columns in region II, segment 2 (18/24, 75%). All of the isolated avulsion fractures of the ACL were located in segment 1, and all those of the PCL in segment 2. The most common type of isolated proximal fibular fracture involved the posterolateral column in region III, segment 2 (23/26, 88%). The most frequent combined TPF and proximal fibular fracture involved all four columns in region IV, segment 2 (107/274, 39.05%). Conclusions All cases of PTFF could be classified by the new 3D Wu classification which should be beneficial for clinical diagnosis, guidance of treatment, statistical analysis, academic communication, and prognosis, and the most frequent PTFF involved all four columns in region IV, segment 2.

Abstract
PURPOSE To assess the accuracy of radiographs in detecting the lateral plateau involvement of medial tibial plateau fractures as well as describe the impact of CT on preoperative planning for this specific fracture morphology. METHODS Radiograph and CT imaging of patients with a Schatzker type IV tibial plateau fractures (AO/OTA 41-B1.2, B1.3 h, B2.2. B3.2, and B3.3) between January 2013 and July 2017 were reviewed by three trauma fellowship-trained orthopedic surgeons to identify fractures of the medial condyle with an intact anterolateral articular surface. RESULTS Lateral plateau involvement was identified in 16 (37%) radiographs and 26 (61%) CT images (p = 0.051). Radiographic detection of lateral plateau involvement demonstrated a sensitivity of 62% and specificity of 100%, and radiographs were able to predict the recommendation for surgical intervention for lateral plateau involvement with a positive predictive value (PPV) of 75% and a negative predictive value (NPV) of 60% compared to recommendations based on CT imaging. Radiographs predicted a need for a separate surgical approach with PPV of 63% and NPV of 70% when compared to recommendations based on CT images. CONCLUSIONS Radiographs are reliable in ruling in lateral plateau involvement of medial plateau fractures, but occult lateral articular extension may only be identified in CT imaging for some cases. Surgical planning may be impacted by CT imaging for this fracture morphology, but further study is warranted to evaluate the correlation between preoperative planning and clinical outcomes.

Abstract
The study aim is to evaluate functional and radio- logical outcomes following a suggested protocol based on the four-column classification for management of posterolateral column tibial plateau fractures.
A prospective cohort study was performed in level I academic center on 42 patients with mean age of 36 years (22-59). Eleven patients had isolated posterolateral column fractures whereas 31 patients had associated columns fractures. According to the suggested protocol, all cases of isolated posterolateral column fracture started treatment via arthroscopic evaluation of soft tissue injuries (menisci and liga- ments), arthroscopically assisted reduction and inter- nal fixation by rafting screws followed by ORIF if plating was needed. If associated with other columns fractures, columns were fixed sequentially in an anti-clockwise direction starting from anteromedial column.
Average follow up was 26 months. Mean time to union was 16.3 (12-22) weeks. No radiological evidence of loss of coronal or sagittal alignment was detected at final follow up. Five patients had an average depression of 5 millimeters that did not need further intervention at this short-term follow up. Mean KOOS was 81 (72- 88). The average knee range of motion was (0° - 127°). One patient had temporary common peroneal nerve injury, one patient had deep infection and two had superficial wound infection.
implementing the suggested protocol gives good to excellent radiological and functional results as regard posterolateral tibial plateau fracture. A larger study group with longer follow up is needed.

Treatment of Isolated Posterolateral Tibial Plateau Fracture with a Horizontal Belt Plate through the Anterolateral Supra-Fibular-Head Approach. BIOMED RESEARCH INTERNATIONAL 2020; 2020:4186712.

Abstract
The posterolateral tibial plateau fracture was not easy to be exposed and fixed with usual techniques. The aim of this study was to investigate the biomechanical stability and clinical outcome of the isolated posterolateral tibial plateau fracture fixed with a single horizontal belt plate through the anterolateral supra-fibular-head approach. Fracture models were created by 18 synthetic tibias and fixed with three different fixation modes. Each group was fixed and tested on the loading machine, and final vertical displacement of the fragment was detected and calculated. Clinically, a retrospective analysis of 12 cases of posterolateral tibial plateau fracture from January 2013 to December 2017 was performed. There were 8 males and 4 females, aged 33-72 years, with an average age of 49.6 years. Isolated posterolateral tibial plateau fractures were identified according to preoperative X-ray and computed tomography scan. Through the modified anterolateral supra-fibular-head approach, the fracture was reduced and fixed by a prebending T-shaped distal radius plate and rafting screws, with bone substitute grafting or autogenous iliac bone implantation. Patients were followed up to a minimum one year of time period, and the outcome was evaluated clinically and radiologically. The biomechanical study shows that horizontal belt plate fixation for the isolated PL tibial plateau fracture can provide sufficient stability, allowing early knee functional exercise and partial weight bearing. For clinical case series, the average operation time in this group was 73.3 ± 10.2 mins (range: 55-90), and the average duration of hospitalization was 9.1 ± 3.3 days (range: 5-16). Patients were followed up for 12-24 months with an average of 16.5 months, and all patients achieved radiological fracture union after an average of 13.7 weeks. At one year after operation, the average knee score of the Hospital for Special Surgery (HSS) scale was 93.2 ± 4.2 points(range: 90-98), the average score of SMFA was 21.1 ± 5.6 points (range: 14-31), and the average knee range of motion (ROM) was 121.48° ± 8.88° (range: 105°-135°). There were 8 cases that were very satisfied and 3 cases that were satisfied with the operation. For an isolated posterolateral tibial plateau fracture, the supra-fibular-head approach can fully expose the fracture site; the horizontal belt plate fixation of the fracture is stable and reliable to allow for early-stage knee rehabilitation, and the outcome of medium-term clinical follow-up was satisfactory.

Abstract
OBJECTIVES The purpose of our study is to evaluate the three-dimensional biomechanical properties of "Barrel Hoop plate" in two kinds of artificial posterolateral tibial plateau fracture fragment (PLF) by using of synthetic models, each of which has an initial amplifying displacement tendency. MATERIAL AND METHODS Thirty-six tibiae models were randomly assigned into two groups with different displacement tendencies: posterior displacement (PD) and lateral displacement (LD). Each model was then fixed with three patterns: Anterolateral plate (AP), Posterolateral plate (PP), and "Barrel Hoop plate" (BHP). Displacement in three axes of vertical, sagittal and horizontal axis was captured by Optotrak Certus motion analysis system. Bluehill 2 software was used for load control and data collection. RESULTS In Model-PD, when the load was over 1000 N, the posterior displacement of Group-PP and Group-BHP were less than Group-AP (P<0.01). The inferior displacement in the vertical axis of Group-PP was larger than both Group-AP and Group-BHP in all the loading set (P<0.01). In Model-LD, both of the lateral displacement in Group-AP and Group-BHP was less than that of Group-PP when the load was over 1000 N (P<0.01). The inferior displacement of Group-AP was less than that of Group-PP in the load of 1500 N (P<0.01). Both of the posterior displacement of Group-AP and Group-BHP was less than that of Group-PP when the loading was 1500 N (P<0.01). The stiffness of Group PP was less than that of Group AP (P<0.01). CONCLUSIONS The results demonstrated that the 2.7 mm "Barrel Hoop plate" had a greater capacity of anti-three-dimension axes displacement of PLF. The 3.5 mm Anterolateral plate had the advantage in anti-lateral displacement and anti-inferior displacement but was weak at anti-posterior displacement of PLF. The 2.7 mm Posterolateral plate was stronger in anti-posterior, however, weak in anti-inferior displacement capacity.

Abstract
Introduction: This study was conducted to evaluate the efficacy of proximal fibular osteotomy (PFO) in terms of pain relief, and improvement in function in medial compartment osteoarthritis (OA) of the knee joint. Materials and methods: This case series study was conducted at the Shaheed Mohtarma Benazir Bhutto Medical College Lyari and United Medical and Dental College of Karachi. Patients with medial compartment knee joint OA were included in the study and patients with bicompartmental or tricompartmental OA, inflammatory joint disease, valgus knee deformity, morbid obesity, or any infectious pathology involving the knee joint were excluded from the study. The medial and lateral joint spaces were measured and recorded preoperatively and postoperatively. Pre- and postoperative values of visual analog scale (VAS) results and the Oxford knee score were recorded. A PFO was performed after getting informed written consent. Results: A total of 60 patients were enrolled in the study; 16 (26.7%) were men, and 44 (73.3%) were women. The mean age of patients was 51.8 ± 4.1 years. The mean preoperative medial joint space measurement on standard anteroposterior radiograph was 1.45 ± 0.28 mm. The mean preoperative lateral joint space was 8.86 ± 1.27 mm. The recorded mean preoperative Oxford knee score was 20.82 ± 1.97 mm. Recorded levels of mean postoperative medial joint space improved to 4.63 ± 0.668 mm, and mean postoperative lateral joint space was 4.72 ± 0.79 mm. Mean recorded levels of VAS for pain postoperatively were 2.32 ± 0.792, which improved significantly from 7.90 ± 0.79. Conclusions: PFO is a good surgical technique for pain relief and functional improvement in patients suffering from medial compartment OA.

[PMID: 30270010 DOI: 10.1016/j.injury.2018.09.031] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2018] [Revised: 08/31/2018] [Accepted: 09/09/2018] [Indexed: 02/06/2023]
Abstract
PURPOSE The existing classification systems of tibial plateau fracture (TPF) are suboptimal for clinical use and academic communication. A more comprehensive and universal classification system with the capability to analyze all patterns of TPF is urgently required to guide the clinical practice. This study aimed to analyze the incidence and fracture characteristics of TPF using a computed tomography-based "four-column and nine-segment" classification. METHODS According to the differentiated morphological characteristics, tibial plateau and proximal fibula were divided into four columns, which were subdivided into nine segments. Tibia plateau injury index (TPII) was innovatively introduced to represent the extent of injury. A total of 698 consecutive adult patients with 704 affected knees were included (377 females, 321 males, mean age 51.6 ± 12.9 years). Fracture mapping was retrospectively analyzed according to the new-style classification system based on the CT imaging. RESULTS 371 (53.2%) left knees and 321 (46.0%) right knees were injured solely and 6 (0.9%) cases sustained bilateral injuries. The rates of one-column, two-column, three-column and all-four-column injuries were 30.5%, 31.5%, 28.0% and 9.9%, respectively. On average, 2.2 ± 1.0 columns and 3.6 ± 2.1 segments were involved, the mean TPII was 5.7 ± 3.0. The rates of mild, moderate and severe comminuted fractures were 50.0%, 37.5% and 12.5%. The most frequently affected columns were lateral column (572, 81.3%) and intermedial column (524, 74.4%), and the less frequently involved columns were the medial column (219, 31.1%) and fibular column (218, 31.0%). The most frequently affected segments were the posterolateral segment (465, 66.1%), anterolateral segment (453, 64.3%) and posteromedian segment (379, 53.8%). The least frequently involved segment was tubercle segment (85, 12.1%). CONCLUSIONS The novel "four-column and nine-segment" classification will be a beneficial classification system for clinical diagnosis, statistical analysis and prognostic judgment of tibial plateau fractures.

A biomechanical evaluation of different fixation strategies for posterolateral fragments in tibial plateau fractures and introduction of the 'magic screw'. Knee 2018; 25:417-426. [PMID: 29678367 DOI: 10.1016/j.knee.2018.03.015] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2017] [Revised: 02/28/2018] [Accepted: 03/26/2018] [Indexed: 02/02/2023]
Abstract
BACKGROUND Posterior plate fixation is biomechanically the strongest fixation method for posterolateral column fracture (PLCF) of the tibial plateau; however, there are inherent deficiencies and risks of a posterior approach. Thus, the 'magic screw' was proposed to enhance fixation stability of the lateral rafting plate used for PLCF. The purpose of this study was to re-examine and compare the stability of different fixation methods for PLCF. METHODS Synthetic tibiae models were used to simulate posterolateral split fractures. The fracture models were randomly assigned into three groups: Group A, fixed with posterolateral buttress plates; Group B, with lateral locking compression plates (LCP); and Group C fixed with lateral LCPs and one 'magic screw'. Gradually increased axial compressive loads were applied to each specimen. RESULTS There was a mean subsidence hierarchy of the posterolateral fragment at different load levels: Group A had the least subsidence, followed by Group C, and Group B had the most. There were no significant differences in the mean loads at different displacements between Group A and Group C. Group A had the highest axial stiffness. Additionally, there was a significant difference in axial stiffness between Group B and Group C. CONCLUSION Biomechanical stability of the combined fixation of the posteriorly positioned lateral rafting plate with the 'magic screw' was much closer to that of posterior plate fixation for split-type PLCF. The necessity of posterior fixation through a posterior approach may be reduced for selected patients.

Abstract
INTRODUCTION The selection of a surgical approach for buttressing posterolateral tibial plateau fractures is controversial. OBJECTIVE This study compared the surgical exposure area between the reversed L posteromedial approach (R-PM) and the posterolateral (PL) approach using the lateral plateau width as a metric. MATERIALS AND METHODS Twenty lower extremities from fresh frozen cadavers were included. The R-PM approach was used first and the boundary of the posterior tibial cortex exposure was marked with metal pins. With the same specimens, the PL approach was then performed and the exposure area was marked. After removing all soft tissue, an imaginary line was drawn from the lateral plateau rim anterior to the fibular head (L) to the posteromedial ridge of the tibia (M). Additional metal pins were used to indicate bony reference landmarks at the joint line on the posterior tibial plateau, including the lateral tibial spine (S), the lateral boundary with the PM approach (LPM) and the lateral boundary with the PL approach (LPL). All distances were measured using S as the reference point. RESULTS The average distance from S to L, referred to as the lateral plateau width (A), was 32.62 mm. The average distances from S to LPM (B) and from S to LPL measured as a percentage of A were 43.72 and 81.41%, respectively. The average R-PM approach blind distance from LPM to LPL (C) as a percentage of the lateral plateau width was 58.45%, while the distance LPL to L (D), which represents the invisible blind distance with both approaches, was 15.37% of that width. CONCLUSIONS The PL approach provides better access for buttressing the posterolateral tibial plateau fracture than the R-PM approach. With the R-PM approach, the blind area on the lateral plateau which can be accessed only by the PL approach starts approximately at 43.72% and ends at 81.41% of the lateral tibial plateau width. When a fracture is located in this zone, the posterolateral approach is recommended.

Abstract
BACKGROUND A posterolateral column fracture of the tibial plateau (PLCF) is not uncommon, especially lateral and bicondylar tibial plateau fractures. Currently, there is no consensus on the methods of surgical treatment for PLCF, including the surgical approach or the fixation strategy. Though various posterior approaches have been explored and can allow posterior buttress plate fixation, the necessity of a posterior approach with fixation for PLCFs is increasingly questioned. Meanwhile, there is no literature to analyse the morphological features of PLCFs. None of the available surgical techniques can solve all of the problems of PLCFs. METHODS From February 2016 to June 2016, an inconsecutive series of 16 patients who suffered Schatzker type II tibial plateau fractures involving the posterolateral column were selected based on an analysis of the morphological characteristics of PLCFs. The patients were all treated by lateral rafting plate fixation with magic screw implantation through the extended lateral approach. RESULTS According to PLCF morphology, 4 patients had mild slope-type depression fractures (MSDF) of the articular surface, and the other 12 patients had block-type splitting fractures (BSF). After a 12-month follow-up period, there were no complications related to the fixation technique and no significant changes in limb alignment. At the final follow-up, the average range of motion (ROM) of the affected knees was 2.3°-125°, and the average HSS score was 94.2. CONCLUSIONS The selected patients who suffered Schatzker type II fractures involving the posterolateral column could be successfully treated via lateral rafting plate fixation with the magic screw technique. For PLCF treatment, magic screw fixation is a valuable technique that may reduce the utilization of posterior approaches and posterior fixations.

Abstract
OBJECTIVE To prospectively study the outcome of surgically treated split depression lateral tibial plateau fractures extending into the posterior column using the extended posterolateral approach. METHODS Twenty-one patients with split depression lateral tibial plateau fractures (AO: 41-B3) with extension into the posterior column were treated with open reduction and internal fixation through an extended posterolateral approach with osteotomy of the fibular neck±Gerdy tubercle. Follow up radiographs was assessed for quality of articular reduction and limb axis. Functional assessment was performed at last follow up using the Tegner-Lysholm score. Complications pertaining to the surgical approach were recorded. RESULTS The approach was performed in 15 patients with a fibular neck osteotomy alone and 6 patients required a Gerdy's tubercle osteotomy also. All fractures and osteotomies had united. Anatomical articular reduction was achieved in 16 patients. Radiological limb alignment was restored in all patients except for a reversed posterior slope in 1 patient. Arthritic changes were seen in 3 patients. The mean Tegner-Lysholm score was 87.3 (range: 76-95) at last follow up. No specific complications related to the surgical approach like common peroneal nerve injury and lateral instability of the knee was encountered. CONCLUSION The extended posterolateral approach offers excellent exposure posterior to the fibular head to perform articular reduction and fixation achieving satisfactory radiological and functional results in split depression lateral tibial plateau fractures extending into the posterior column.

Abstract
PURPOSE The best approach for treating posterolateral tibial plateau fractures remains controversial. The clinical results of an extended anterolateral approach on such fractures are discussed in this study. METHODS Between 2010 and 2011, ten patients with posterolateral tibial plateau fracture were treated using an extended anterolateral approach with a proximal tibial locking compression plate. The epidemiological data, operation details, and clinical outcomes over 26.4 ± 2.3 months (range 24-30 months) of follow-up were prospectively collected and analyzed. RESULTS The average surgical duration was 91.5 ± 18.7 min (range 80-130 min). An anatomic reduction rate of 90 % (9/10) was observed although one patient with a lateral comminuted fracture and dislocation presented a 2-mm joint surface depression postoperatively. The average fracture healing time was 10.6 ± 1.8 weeks (range 8-14 weeks), with an average hospital for special surgery knee score of 95.3 ± 6.5 points (range 80-100 points), an average knee flexion of 119.8° ± 17.2° (range 95°-140°) and an average knee extension of 2.1° ± 2.1° (range 0°-6°). No complications were found. CONCLUSIONS The extended anterolateral approach with a proximal tibial compression plate offers direct and complete surgical exposure and may provide an effective method for the surgical treatment of posterolateral tibial plateau fractures. LEVEL OF EVIDENCE Therapeutic, Level IV.

Abstract
PURPOSE This study was aiming to investigate intraoperative and postoperative complications and outcomes of a posterior reversed L-shaped approach (PRLA) in the treatment of the tibial plateau fractures. METHODS Inclusion criterion was tibial plateau fractures treated through the PRLA either separated or combined with other approaches. Main exclusion criterion was poly-trauma patients. Ninety-five patients with tibial plateau fractures from a prospectively collected database were included and followed in this study. The intraoperative and postoperative complications consisted of vascular and nerve injury, wound infection, dehiscence, haematoma, nonunion, skin necrosis and skin paresthesia. Hospital for Special Surgery Knee Score (HSS) was adopted to evaluate patients' knee function while Short Form 36 Health Survey (SF-36) was used to investigate the patients' general health status. RESULTS Patients' average age was 46.2 years old (range, 22.0-89.0). The fractures were mainly from high energy injuries involving posterior (and medial) column. 78 of 95 cases were combined with an additional anterolateral approach due to the lateral column involvement. The average follow-up was 52.0 months (range, 12.4-102.6). The total complications rate was 4.2% (4/95). Intraoperative complications occurred in two patients (2.1%). One suffered a popliteal artery injury resulted from an antero-posteriorly drilled K-wire. The patient had a loss of 7° knee extension at one year's follow-up. The other endured an injury of nutrient vessel within the medial head of gastrocnemius. Postoperative skin paresthesia occurred in two patients (2.1%). The other complications associated with the PRLA were not observed. The mean HSS score was 96.1 (range, 80-100). The mean SF-36 score was 94.2 (range, 80-100). CONCLUSIONS The posterior reversed L-shaped approach allows satisfied visualization of the medial and posterior tibial plateau and has promising clinical results with low complication occurrence. It can be recommended as a routine approach for the treatment of the tibial plateau fractures involving the posterior column.

Abstract
Periarticular fractures around the knee are a challenge for the orthopaedic surgeon. When these fractures are presented in the context of a multiple trauma patient, they are even more difficult to manage because the treatment approach depends not only on the fracture itself, but also on the patient's general condition. These fractures, caused by high-energy trauma, present complex fracture patterns with severe comminution and major loss of articular congruity, and are often associated with vascular and nerve complications, particularly in the proximal tibia, due to its anatomical features with poor myocutaneous coverage. They are almost always accompanied by soft tissue injury. The management of polytrauma patients requires a multidisciplinary team and accurate systemic stabilization of the patient before undertaking orthopaedic treatment. These fractures are usually addressed sequentially, either according to the general condition of the patient or to the local characteristics of the lesions. In recent decades, various fixation methods have been proposed, but there is still no consensus as to the ideal method for stabilizing these fractures. In this paper, we describe the general characteristics of these fractures, the stabilization methods traditionally used and those that have been developed in recent years, and discuss the treatment sequences proposed as most suitable for the management of these injuries.

Abstract
INTRODUCTION This study aimed to investigate the surgical techniques and the clinical efficacy of combined approaches for the treatment of Schatzker type II tibial plateau fractures involving the posterolateral column [lateral and posterolateral columns (LPCs) fractures] in a prospective cohort. MATERIALS AND METHODS From January 2007 through December 2010, a total of 65 patients with LPCs underwent dual-plate fixation via a combined anterior and posterior approach. The anterior and posterior approaches were the conventional anterolateral approach and a posteromedial inverted L-shaped approach, respectively, with the patients in a floating position. RESULTS Ultimately, 41 patients were followed up for a mean period of 52.5 months. All fractures healed. The mean time to radiographic bony union was 15.2 weeks and the mean time to full weight-bearing was 18.7 weeks. No parameter associated with knee alignment changed significantly between immediately postoperation and 2 years postoperation. No collapse of the reduced articular surface was detected. Two years postoperation, the mean Hospital for Special Surgery score was 92.3; the mean Short Form-36 score was 90.1, and the mean range of knee motion was 1.7°-123.6° (extension-flexion). Two patients suffered dehiscence of the anterolateral incision and another suffered partial necrosis at the margin of the posteromedial incision postoperatively. All healed in response conservative treatment. Another two patients experienced numbness in the posteromedial inferior region of the calf. No implant loosening, breakage, fixation failure, or other complication was observed during follow-up. CONCLUSIONS LPCs are not uncommon. Careful preoperative analysis of computed tomography images and impeccable preparation are necessary to avoid neglecting a posterolateral column fracture. It is inappropriate to generalize one scenario for all Schatzker type II fractures: a single approach cannot address all subtypes of these fractures. Dual-plate fixation via a combined approach is an effective treatment for LPCs.
