Treatment Strategies for Complex Fractures of the Tibial Plateau With External Circular Fixation and Limited Internal Fixation

Management of tibial plateau fractures: a fresh review

Tibial plateau fractures are complex injuries which carry significant morbidity and economic burden. They can present complex geometry depending upon the direction of the force and position of the limb and are often associated with significant soft-tissue injury. While the goals of adequate reduction, stable fixation, and early mobilization remain unchanged, the management of these injuries can be challenging even to experienced orthopaedic surgeons. Lacking consensus, this review aims to provide a summary of current state of orthopaedic practice in the face of tibial plateau fractures. A PubMed search for relevant recent articles as well as a reading of classical articles on tibial plateau fractures was carried out. The focus remained on articles concerned with management modalities and recent advances. A review of some classification systems was also done and included. A great majority of these fractures need operative fixation while respecting the soft tissues. Numerous methods have been reported in the literature including but not limited to plates, screws, external fixators, arthroscopy assisted methods, balloon-cement tibioplasty, or a combination thereof. There is a shortage of randomized controlled trials comparing various operative methods. This article provides a review of various techniques and latest advances made in the management of tibial plateau fractures. The key to achieving optimal functional outcome is using a tailored approach to the individual patient accounting for factors related to the injury pattern, type of host, surgical skills and experience, and local availability of implant devices while taking care of soft tissue. While there is no gold standard, a staged procedure is recommended with early spanning and definitive fixation at later stage by any appropriate methods while respecting the soft tissue, achieving anatomical reduction and adequate fixation and, early rehabilitation.

Treatment of high-energy intra-articular fractures of tibia with Ilizarov external fixator in adults: A tertiary centre experience

OBJECTIVE

To evaluate the clinical and radiological outcomes of the Ilizarov fixator in the proximal and distal fractures of the tibia.

MATERIALS AND METHODOLOGY

This retrospective study reviewed 59 patients having high-energy intra-articular proximal and distal tibia fractures associated with severe soft-tissue injury, who were managed surgically with an Ilizarov fixator. The functional outcome was evaluated by using the American Orthopaedic Foot and Ankle Society scoring system (AOFAS) and the Association for the Study and Application of the Method of Ilizarov (ASAMI) Italy scoring system for tibial plateau and plafond fractures respectively.

RESULTS

The most common mode of injury was road traffic accidents. According to the Gustilo open fracture classification, there were 16 patients with grade-I and nine with grade II open fractures. The remaining had closed fractures. According to the Schatzker classification of plateau fractures, 20 were graded as type V and 15 as type VI. According to the AO classification of plafond fractures, 12 fractures were graded as Type-43C1, 5 as Type-43C2, and 7 as Type-43C3. There was delayed union in 11 proximal and four distal fractures, all of which achieved union without additional bone grafting. In proximal fractures, according to AOFAS, out of 35, 26 had an acceptable while nine had a fair result. In distal fractures, according to ASAMI, out of 24, 16 had an acceptable while five had fair results. There were 192/448 wires in 58 patients with pin site infection; all were superficial and settled. Posttraumatic joint arthrosis was noted in nineteen.

CONCLUSIONS

The postoperative clinical and radiological outcome indicated that primary Ilizarov external fixator is a reliable minimal invasive surgery and definitive fixation method for high-energy intra-articular proximal and distal tibial fractures with compromised soft-tissue. It also offers early stabilisation and painless joint motion without a high rate of complications.

Treatment of Schatzker Type II-VI Tibial Plateau Fractures by Means of Syndesmotaxis Using an Ilizarov External Fixator and Postoperative CT Evaluation

Introduction Tibial plateau fractures are more common in young patients following high-energy trauma. In this study, we aim to evaluate the articular surface reduction quality by means of postoperative computer tomography (CT) in Schatzker type II-VI tibial plateau fractures treated with an Ilizarov frame. Materials and methods This case series study included 45 patients with a mean age of 39.5 years (range: 18 to 65 years) with a Schatzker type II-VI tibial plateau fracture. The surgical technique was a mini-open reduction of the articular surface impaction followed by application of an Ilizarov circular frame with knee bridging. Pre- and postoperative CT scan evaluation was performed in all of the patients. Outcomes were measured using the American Knee Society Score (AKSS). Mean outpatient follow-up was of at least 12 months (range: 12 to 21 months). Mean time for fracture consolidation was 15.5 weeks (range: 13 to 19 weeks). According to the degree of postoperative articular surface impaction, patients were grouped as follows: 11 had less than 2 mm of depression, 27 had 2 to 4 mm of depression, and 7 over 4 mm of depression. Results Patients with articular surface impaction of more than 4 mm presented statistically significant lower values of AKSS compared to those with impaction of lower than 2 mm (p<0.001 ) and 2-4 mm (p<0.001). Patients with joint alignment equal to or more than 5^° presented statistically significant lower values of AKSS compared to those with lower than 5^°. Conclusions Schatzker type II-VI tibial plateau fractures may be treated successfully with mini-open reduction and the application of an Ilizarov frame. The increase of articular surface impaction by 1 mm causes reduction of AKSS by 15 units. Patients with joint alignment equal to or more than 5^° present lower values of AKSS. The preoperative CT scan is important and useful in planning the surgical intervention no matter the classification system is used.

High energy trauma with complex fracture of the right tibial plateau, compartment syndrome and infection in a professional freestyler motorcyclist

BACKGROUND AND AIM OF THE WORK

High-energy tibial plateau fractures are complex lesions that may be associated with extensive soft tissue damages and severe complications, such as compartment syndrome and neurological injuries. This case report interests a professional motocross freestyler with complex tibial plateau fracture associated to compartment syndrome and partial common peroneal nerve impairment which complicated with a dehiscence of the surgical wound and infection after plate and screws fixation. One year later, despite the complexity of the fracture, the gravity of the soft tissue lesions and subsequent complications, the patient healed. This satisfactory result depended on the correct management in terms of type of treatment and timing.

Ilizarov Fixation Method of Tibia Plateau Fractures: A Prospective Observational Study

BACKGROUND

 Tibia plateau fractures are most commonly managed with open reduction and internal fixation (ORIF) technique, external fixation via minimally invasive technique are an excellent alternative. The aim of this study was to assess the results of tibia plateau fractures by using the Ilizarov external fixator. The analysis was done both clinically and radiologically.

METHODOLOGY

 Some 72 patients with isolated tibia plateau fractures were brought to ED and clinics and assessed. The fractures were classified according to Schatzker Tibia Plateau Fracture classification, only Schatzker type III to VI were included using conventional X-rays. All patients for their tibia plateau fractures underwent surgical correction using Ilizarov technique with full weight bearing and knee range of motion allowed the next day. Patient follow-up up to one year was done. KOOS and self-appraisal were used to evaluate the knee pain and function.

RESULTS

 All the fractures healed with 67 patients achieving a range of motion better than 0-100º. KOOS score shows that patients who had worse fracture patterns (Schatzker-V and VI) have worse global scores (p=0.002); still when managed with an Ilizarov it has been seen that these patients are able to maintain a moderately pain free knee (p=0.013) other aspects of the KOOS. Patients with higher BMI showed to have worsening fracture patterns with 20 out of the 30 overweight patients suffering Schatzker-V (66.67%). We experienced an extremely low rate of pin tract infections with only two debridements required.

CONCLUSION

 Ilizarov external fixation method is a valuable alternative treatment with excellent clinical outcomes and early mobilization.

Biomechanical Analysis of the Behaviour at the Metaphyseal-Diaphyseal Junction of Complex Tibial Plateau Fractures Using Two Circular Fixator Configurations

Background

High-energy tibial plateau fractures are challenges in treatment with controversy over operative stabilisation, especially for fractures with metaphyseal–diaphyseal dissociation. Treatment with percutaneous or minimally invasive direct reduction techniques, usually associated with circular external fixation, has generated interest although there is no consensus regarding the type of external fixation to be used.

Aim

This study aims to compare the two hybrid circular external fixation mountings used to treat the high-energy tibial plateau fractures.

Methods

Two different groups of hybrid circular external fixation frame mountings were assembled using composite tibiae with proximal metaphyseal osteotomies simulating tibial plateau fractures with metaphyseal–diaphyseal dissociation. The standard all-wire frame mounting was assembled, and the comparison frame mounting had the distal K-wires replaced with half-pins. Both groups were tested through cyclic loading between 300 and 1000 N for 10,000 cycles. Interfragmentary linear and rotational displacements were analysed.

Results

The standard frame mounting behaved similarly to a classic Ilizarov frame, allowing greater axial movement (mean, 3.76 ± 0.26 mm in the standard group and 3.02 ± 0.23 mm in the test group) and smaller mediolateral displacement compared with the test frame (mean, 0.17 ± 0.16 mm compared to 0.56 ± 0.12 mm). The test frame behaved more similarly to a linear external fixator and provided greater axial stability, similar anteroposterior displacement, and lower mediolateral stability. Despite these differences, in both groups the axial displacement was greater than the prejudicial nonaxial movements.

Conclusion

Increasing the number of half-pins and decreasing the number of K-wires in hybrid circular external fixation generate frames that tend to behave more similarly to the linear external fixators.

Treatment of open tibial diaphyseal fractures by external fixation combined with limited internal fixation versus simple external fixation: a retrospective cohort study

Background

The treatment of open tibial shaft fractures is challenging. External fixation (EF) is comparatively safe in treating these open injuries, meanwhile it has the advantages of easy application, minimal additional disruption, and convenient subsequent soft tissue repair. Nevertheless, its application is accompanied by a series of problems in alignment and bone healing. Therefore, limited internal fixation (LIF), such as cortical screws, has been used based on the external fixator for better therapeutic effect. The aim of this study is to compare the outcomes of EF combined with LIF and simple EF in the management of open tibial shaft fractures, evaluating the efficacy and safety of using the combined technique in treating such fractures.

Methods

From January 2012 to December 2016, patients with open tibial shaft fractures treated with EF with or without LIF augmentation were identified. A total of 152 patients were included in the analysis, and there were 85 patients in the simple external fixation group and 67 patients in the EF-LIF group. General assessment indicators included the direct cost of hospitalization and the times of first surgery, full weight bearing, and complete union. Infections and complications in union or limb alignment were compared as primary outcomes. Additionally, the number of patients who changed the fixation system for various reasons were analysed.

Results

Effective follow-up of all participants for statistical analysis was obtained. The follow-up time averaged 17.15 months (range: 12.00 to 24.00 months) in the EF group and 16.20 months (range: 12.00 to 19.00 months) in the EF-LIF group. Combined fixation provided shortened time to bear full weight and achieve complete bone union, while requiring additional first surgery time. No significant difference was found in infection rates or direct cost of hospitalization. Delayed union and non-union in the EF-LIF group were significantly decreased (20.9% versus 40.0, 1.5% versus 14.1%, p < 0.05). In limb alignment, patients with combined fixation exhibited reduced malreduction, loss of reduction, and malunion. In terms of secondary fixation, the EF-LIF group showed a markedly lower incidence (5.8% versus 34.1%, p < 0.001).

Conclusion

Compared with simple EF, combined fixation is an effective and safe alternative for management of open tibial diaphyseal fractures. It provides superior initial reduction, better stability and decreases the risk of inferior alignment and delayed union without increasing the risk of infection.

Outcome of complex tibial plateau fractures with Ilizarov external fixation with or without minimal internal fixation

PURPOSE

To evaluate the clinico-radiological outcome of complex tibial plateau fractures treated with Ilizarov external fixation with or without minimal internal fixation.

METHODS

This retrospective review was conducted on all the cases of Schatzker types V and VI tibial plateau fractures treated by Ilizarov external fixation between July 2006 and December 2015 with the minimum follow-up duration of one year. There were 30 patients: 24 males and 6 females, mean age 43.33 years, and mean follow-up 3.6 years. Three of them were open fractures; 15 cases were Schatzkertype V fractures and the other 15 type VI. According to AO/OTA classification, there were 11 type C1, 12 C2 and 7 type C3 fractures. Outcome assessment was made with American Knee Society Score (AKSS) and Rasmussen's Radiological Score (RRS) at final follow-up.

RESULTS

Out of the 30 cases, mini-open reduction was performed in 7, bone graft in 4, minimal internal fixation in 10 and knee temporary immobilisation in 11 patients. Mean duration of external fixation was 11.8 weeks. All fractures united. Pin tract infections in 7 and common peroneal neuropathy in 2 patients were self-limiting. Two patients had axial misalignment of less than 10°. At final follow-up, the mean knee range of motion was 114.7, mean AKSS 81.5 and mean RRS 16.7. On statistical analysis, Schatzker type of fractures, use of minimal internal fixation and knee-spanning did not influence the final outcome.

CONCLUSION

Ilizarov external fixator with or without minimal internal fixation provides acceptable outcome for complex tibial plateau fractures. Care must be taken to look for minor loss of alignment, especially in Type VI Schatzker fractures after removal of the fixator. However small sample size precludes firm conclusions.

The use of bidirectional rapid reductor in minimally invasive treatment of bicondylar tibial plateau fractures: preliminary radiographic and clinical results

BACKGROUND

Minimally invasive treatment of complex tibial plateau fracture represents one of the most challenging problems in orthopedic surgery. We intended to describe the percutaneous surgery involving an originally designed traction device which might facilitate the closed reduction for bicondylar tibial plateau fractures. Further, to assess the clinical outcomes of this minimally invasive technique.

METHODS

Between December 2015 and July 2016, Twenty-one patients, mean age 43.71 ± 13.80 years, suffering from a bicondylar tibial plateau fracture (AO/OTA 41-type C) were included. All fractures were firstly reduced by skeletal traction with the aid of bidirectional rapid reductor, and residual depressed fragments were treated with minimally invasive bone tamp reduction. We then evaluated at a minimum follow-up of one year: (1) the rate of complications, (2) the radiographic outcomes (the amount of depression, tibial plateau widening, tibial plateau angle and posterior slope angle) and (3) the clinical outcome (Rasmussen scoring system).

RESULTS

All patients had their fractures healed without secondary displacement. No instrument-related complications occurred during operation. Post-operatively, superficial infection was found in two patients and donor-site morbidity was found in one patient. We observed a < 5 mm step-off in 100% of patients and a < 5 mm plateau widening in 95.5% of patients. Three patients were considered indicative of malalignment with TPA > 90° or PSA > 15°. At last evaluation, the Rasmussen clinical score was excellent in 11 patients (52.3%), good in 9 (42.9%) and fair in 1 (4.8%), and the radiological score was excellent in seven patients (33.3%), good in 14 (66.7%).

CONCLUSIONS

The bidirectional rapid reductor facilitates the minimally invasive treatment of bicondylar tibial plateau fracture. The patients exhibited excellent functional recovery. These results should be validated with a larger group of patients and longer period results.

Treatment of fractures of the tibial plateau (Schatzker VI) with external fixators versus plate osteosynthesis

INTRODUCTION

The purpose of this study was to determine the effectiveness of circular external fixation (CEF) as a definitive treatment option for patients with complex tibial plateau fractures (Schatzker VI) compared with the outcomes of a fixed angle locking plates' group.

METHODS

Level III evidence. Retrospective, comparative study in a Level I Trauma Center. Fourteen patients treated with CEF (Group A) were compared to fourteen patients treated with minimal invasive angle locking plates (Group B). The mean time from fractures to surgery was 19 days for Group A with a mean ISS of 24 and 7 days for Group B with a mean ISS of 14. The main outcome measures were clinical and radiographic.

RESULTS

Complete union was obtained in Group A at an average of 22 weeks and at 17 weeks in Group B. Two patients developed non-union, one in each group. Normal alignment was observed in both groups, no statistical differences were observed in Paley's anatomical posterior proximal tibial angle (aPPTA) and mechanical medial proximal tibial angle (mMPTA) between two groups. Results based on the Association for the Study and Application of the Method of Ilizarov criteria for Group A: 71% excellent and 29% good as far as bone outcomes are concerned and as 57% excellent, 37% good, and 7% fair for functional outcomes.

CONCLUSIONS

Definitive fixation with circular external fixator is effective in complex Schatzker VI tibial plateau fractures. Advantages include maintaining the frame till union, reduced risk of infection, early mobilization, restoration of the normal lower extremity alignment, versatility, and improved union rate in patients with multiple traumatic injuries, infection, and soft tissue injuries.

Characteristics of postoperative weight bearing and management protocols for tibial plateau fractures: Findings from a scoping review

OBJECTIVE

To identify and describe the characteristics of existing practices for postoperative weight bearing and management of tibial plateau fractures (TPFs), identify gaps in the literature, and inform the design of future research.

METHODS

Seven electronic databases and clinical trial registers were searched from inception until November 17th 2016. Studies were included if they reported on the surgical management of TPFs, had a mean follow-up time of ≥1year and provided data on postoperative management protocols. Data were extracted and synthesized according to study demographics, patient characteristics and postoperative management (weight bearing regimes, immobilisation devices, exercises and complications).

RESULTS

124 studies were included involving 5156 patients with TPFs. The mean age across studies was 45.1 years (range 20.8-72; 60% male), with a mean follow-up of 34.9 months (range 12-264). The most frequent fracture types were AO/OTA classification 41-B3 (29.5%) and C3 (25%). The most commonly reported non-weight bearing time after surgery was 4-6 weeks (39% of studies), with a further 4-6 weeks of partial weight bearing (51% of studies), resulting in 9-12 weeks before full weight bearing status was recommended (55% of studies). Loading recommendations for initial weight bearing were most commonly toe-touch/<10kg (28%), 10kg-20kg (33%) and progressive (39%). Time to full weight bearing was positively correlated with the proportion of fractures of AO/OTA type C (r=0.465, p=0.029) and Schatzker type IV-VI (r=0.614, p<0.001). Similar rates of rigid (47%) and hinged braces were reported (58%), most frequently for 3-6 weeks (43% of studies). Complication rates averaged 2% of patients (range 0-26%) for abnormal varus/valgus and 1% (range 0-22%) for non-union or delayed union.

CONCLUSIONS

Postoperative rehabilitation for TPFs most commonly involves significant non-weight bearing time before full weight bearing is recommended at 9-12 weeks. Partial weight bearing protocols and brace use were varied. Type of rehabilitation may be an important factor influencing recovery, with future high quality prospective studies required to determine the impact of different protocols on clinical and radiological outcomes.

What's new in the management of complex tibial plateau fractures?

The management of complex tibial plateau fractures is ever evolving. The severity of the injury to the surrounding soft tissues influences the timing and the method of fixation. Minimal invasive techniques continue to dominate our philosophy of reduction and reconstruction whereas augmentation of depressed intra-articular fragments remains an accepted strategy to maintain reduction and prevent secondary collapse. Locking plates, conventional plates and fine wire fixators all have been used successfully with satisfactory outcomes. In this article we report on the latest advances made in the management of these complex injuries.

Ilizarov management of Schatzker IV to VI fractures of the tibial plateau

This study aimed to determine the long-term functional, clinical and radiological outcomes in patients with Schatzker IV to VI fractures of the tibial plateau treated with an Ilizarov frame. Clinical, functional and radiological assessment was carried out at a minimum of one year post-operatively. A cohort of 105 patients (62 men, 43 women) with a mean age of 49 years (15 to 87) and a mean follow-up of 7.8 years (1 to 19) were reviewed. There were 18 type IV, 10 type V and 77 type VI fractures. All fractures united with a mean time to union of 20.1 weeks (10.6 to 42.3). No patient developed a deep infection. The median range of movement (ROM) of the knee was 110o and the median Iowa score was 85.

Our study demonstrates good long-term functional outcome with no deep infection; spanning the knee had no detrimental effect on the ROM or functional outcome.

High-energy fractures of the tibial plateau may be treated effectively with a fine wire Ilizarov fixator.

Retrospective review of tibial plateau fractures treated by two methods without staging

INTRODUCTION

Management of complex tibial plateau fractures can be challenging for orthopaedic surgeons. Wide disagreement still remains about the best surgical technique to use in these fractures. The purpose of this study was to compare the results of complex tibial plateau fractures treated by an open reduction and internal fixation (ORIF) versus hybrid external fixation (EF) in term of clinical and functional outcomes.

MATERIALS AND METHODS

We retrospectively examined a series of 79 patients affected by tibial plateau fractures admitted at our Department between January 2006 and November 2011. Forty-one patients were treated using a hybrid EF; in 38 cases, ORIF technique was used. Clinical evaluation was performed using the method of Rasmussen; functional assessment was made using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) questionnaire. Residual pain was detected using a Numeric Rating Scale (NRS).

RESULTS

The average time to union in the plate group was 17.2 weeks (9.1-45 weeks), while in the EF one 15.9 (7.5-32). The mean overall hospital stay was 14.2 days for the ORIF group and 7.8 for the EF group. At the last follow-up, the mean Rasmussen score was 24.9 (good) in the patients treated with ORIF and 25 (good) in those who received EF. The WOMAC index disclosed a relatively higher score in the EF group (80.5 ORIF-84.2 EF). Pain evaluation revealed no differences between the groups. In terms of complications, deep infection occurred in four (10.5%) patients belonging to the ORIF group and 2 (4.9%) to EF one. Signs of osteoarthritis (OA) were observed in 4 (10.5%) knees that had open reduction and in 11 (26.9%) that had a hybrid external fixator.

CONCLUSIONS

Either ORIF or hybrid EF represents a valid treatment option in complex tibial plateau fractures. However, hybrid external fixation has shown relative better functional outcome results, relative lower rate of infection and decreased hospital stays. These aspects make of EF our best choice in case of high-energy complex tibial fractures.

Management of Proximal Tibia Fractures Using Wire Based Circular External Fixator

INTRODUCTION

Management of high grade proximal tibia or tibial plateau fractures is often associated with complications. The use of wire fixators for the definitive treatment of such fractures entails a minimally invasive technique of insertion that gives good fracture reduction and stability combined with minimal postoperative complications.

AIM

To assess the outcome of treatment of such fractures by the use of Joshi's external stabilization system (JESS), which is a wire based, circular external fixator system.

MATERIALS AND METHODS

A prospective, uncontrolled study was done using JESS on 20 consecutive patients of high energy fractures of the tibial plateau, classified according to the Schatzker's classification as type VI.

RESULTS

In this series, road traffic accidents accounted for most of the injuries (n=12), while pedestrian accidents (n=4), injury due to fall from height (n=3) and injury due to fall while playing (n=1) were the other modes of injury. The mean patient age was 39.4 years. The mean follow up period was 24 weeks. In this study, using Knee society score evaluation, excellent results were seen in 12 patients (60%), good results were seen in 5 patients (25%), fair in 2 patients (10%) and bad in 1 patient (5%). Complications seen were, pin tract infections in two cases (10%) which resolved with dressings and oral antibiotics and one case of non-union (5%), in which the tibial plateau fracture extended into proximal 1/3 of the tibial shaft with severe comminution. No other complication was encountered.

CONCLUSION

JESS is a simple, inexpensive and useful technique in the management of high grade tibial plateau fractures.

External versus internal fixation for bicondylar tibial plateau fractures: systematic review and meta-analysis

Background

It is uncertain whether external fixation or open reduction internal fixation (ORIF) is optimal for patients with bicondylar tibial plateau fractures.

Materials and methods

A systematic review using Ovid MEDLINE, Embase Classic, Embase, AMED, the Cochrane Library, Open Grey, Orthopaedic Proceedings, WHO International Clinical Trials Registry Platform, Current Controlled Trials, US National Institute for Health Trials Registry, and the Cochrane Central Register of Controlled Trials. The search was conducted on 3rd October 2014 and no language limits were applied. Inclusion criteria were all clinical study designs comparing external fixation with open reduction internal fixation of bicondylar tibial plateau fractures. Studies of only one treatment modality were excluded, as were those that included unicondylar tibial plateau fractures. Treatment effects from studies reporting dichotomous outcomes were summarised using odds ratios. Continuous outcomes were converted to standardized mean differences to assess the treatment effect, and inverse variance methods used to combine data. A fixed effect model was used for meta-analyses.

Results

Patients undergoing external fixation were more likely to have returned to preinjury activities by six and twelve months (P = 0.030) but not at 24 months follow-up. However, external fixation was complicated by a greater number of infections (OR 2.59, 95 % CI 1.25–5.36, P = 0.01). There were no statistically significant differences in the rates of deep infection, venous thromboembolism, compartment syndrome, or need for re-operation between the two groups.

Conclusion

Although external fixation and ORIF are associated with different complication profiles, both are acceptable strategies for managing bicondylar tibial plateau fractures.

Comparative study of single lateral locked plating versus double plating in type C bicondylar tibial plateau fractures

BACKGROUND

Bicondylar tibial plateau fractures are complex injuries and treatment is challenging. Ideal method is still controversial with risk of unsatisfactory results if not treated properly. Many different techniques of internal and external fixation are used. This study compares the clinical results in single locked plating versus dual plating (DP) using two incision approaches. Our hypothesis was that DP leads to less collapse and change in alignment at final followup compared with single plating.

MATERIALS AND METHODS

61 cases of Type C tibial plateau fractures operated between January 2007 and June 2011 were included in this prospective study. All cases were operated either by single lateral locked plate by anterolateral approach or double plating through double incision. All cases were followed for a minimum of 24 months radiologically and clinically. The statistical analysis was performed using software SPSS 10.0 to analyze the data.

RESULTS

Twenty nine patients in a single lateral locked plate and 32 patients in a double plating group were followed for minimum 2 years. All fractures healed, however there was a significant incidence of malalignment in the single lateral plating group. Though there was a significant increase in soft tissue issues with the double plating group; however, there was only 3.12% incidence of deep infection. There was no significant difference in Hospital for special surgery score at 2 years followup.

CONCLUSION

Double plating through two incisions resulted in a better limb alignment and joint reduction with an acceptable soft tissue complication rate.

Tibial plateau lesions. Surface reconstruction with a biomimetic osteochondral scaffold: Results at 2 years of follow-up

INTRODUCTION

Tibial plateau articular pathology caused by post-traumatic or degenerative lesions is a challenge for the orthopaedic surgeon and can lead to early osteoarthritis. The aim of the present study was to evaluate the results of treatment of these complex defects with implantation of an osteochondral scaffold, which is designed to target the cartilage surface and to reconstruct joint anatomy by addressing the entire osteochondral unit.

MATERIALS AND METHODS

Eleven patients (5 female and 6 male) with a mean age of 37.3 ± 11.0 years and osteochondral lesions of the tibial plateau (mean 5.1 ± 2.7 cm(2); range 3.0-12.5 cm(2)) were treated with the implantation of an osteochondral biomimetic collagen-hydroxyapatite scaffold (Maioregen(®), Fin-Ceramica, Faenza, Italy). Comorbidities were addressed taking care to restore the correct limb alignment. Patients were evaluated pre-operatively and prospectively followed-up for 2 years using the International Knee Documentation Committee (IKDC) subjective and objective scores; activity level was documented using the Tegner score.

RESULTS

Three patients experienced minor adverse events. No patients required further surgery for treatment failure during the study follow-up period, and 8 patients (72.7%) reported a marked improvement. The IKDC subjective score improved from 42.5 ± 10.2 before treatment to 69.8 ± 19.0 at 12 months (p<0.05), with stable results at 24 months. The IKDC objective score increased from 27.3% normal and nearly normal knees before treatment to 85.7% normal and nearly normal knees at 24 months of follow-up. The Tegner score increased from 2.3 ± 2.1 before treatment to 4.8 ± 2.4 at 12 months (p<0.05), and was stable at the final follow-up.

CONCLUSION

The present study on the implantation of an osteochondral scaffold for the treatment of tibial plateau lesions showed a promising clinical outcome at short-term follow-up, which indicates that this procedure can be considered as a possible treatment option, even in these complex defects, when comorbidities are concomitantly addressed.

An efficacy analysis of surgical timing and procedures for high-energy complex tibial plateau fractures

OBJECTIVE

To identify the most effective treatment for application to high-energy complex plateau fractures.

METHODS

125 patients with closed high-energy complex tibial plateau fractures who had been surgically treated between 2003 and 2010 were reviewed retrospectively. Five procedure methods were studied (e.g. four open reduction and internal fixations, and close reduction via a minimal incision with hybrid external fixation) in five surgical timings, with a control group. The incidence of wound complications after operative treatment in the five surgical timings and the clinical effects of the five surgical procedure options were evaluated statistically. A postoperative follow-up ranging 26-110 months (mean, 36.5 months) was performed.

RESULTS

Among the various groups, the respective overall wound complication incidences were 20.0%, 41.6%, 33.3%, 2.5%, and 16.7% within 4 hours, 4 hours to 3 days, 3-5 days, 5-8 days, and more than 8 days after injury. Failed fixation was clearly observed in Group 1 (23.1%, 6/26) and Group 5 (21.7%, 5/23) (P < 0.05). Significant differences were also found among Group 2 (92.6%), Group 3 (93.3%), and Group 5 (69.6%), in terms of the good and excellent rate of joint function according to the Rasmussen score (P < 0.05).

CONCLUSION

The optimal surgical timing is within 4 hours after trauma, for which no obvious swelling was observed in the limbs. This is followed by surgical timing within 5-8 days, after which trauma showed only subsided limb swelling. Dual plating provides the best stabilization option, as it allows early joint mobilization, cartilage regeneration, and joint remodeling, thus decreasing the risk of joint stiffness. Hybrid external fixation may provide relative stability to maintain fracture alignment without the need for massive soft tissue dissection, and also minimizes blood loss and potential soft tissue complications.

MDCT and MRI for the diagnosis of complex fractures of the tibial plateau: A case control study

The aim of this study was to evaluate the clinical value of multidetector-row computed tomography (MDCT) and magnetic resonance imaging (MRI) in the diagnosis and treatment of complex fractures of the tibial plateau. A total of 71 patients with complex fractures of the tibial plateau (estimated Schatzker classifications III, V and VI) were included in this study. The X-ray, MDCT and MRI data obtained from the patients were analyzed. MDCT was the most sensitive method in the diagnosis of tibial articular surface collapse, cruciate ligament tibial avulsion fracture, degree of fracture comminution and degree of fracture displacement (P<0.01). MRI was the most sensitive method in the diagnosis of injuries of the cruciate and collateral ligaments, menisci and cartilage peeling of the articular surfaces (P<0.01). MDCT and MRI were demonstrated to be more sensitive than X-rays for the diagnosis of insidious damage around the knee.

Biomechanical comparison of axial load between cannulated locking screws and noncannulated cortical locking screws

The goal of this study was to compare the biomechanical stability of cannulated locking screws and noncannulated cortical locking screws in a periarticular locking plate. Twelve fresh-frozen porcine tibias with a 1-cm gap created distal to the tibial plateau were used to simulate an unstable proximal tibial fracture. All specimens were fixed with a periarticular proximal lateral tibial locking plate and divided into 2 groups based on whether the proximal metaphyseal screw holes of the plate were inserted with either cannulated locking screws or noncannulated cortical locking screws. An axial compressive load was applied to cause failure in each specimen using a materials testing instrument. The axial stiffness and maximum failure strength in axial loading were recorded. Axial stiffness of the constructs using noncannulated cortical locking screw was significantly higher than that of the constructs using cannulated locking screws (P=.006). Axial failure strength of the constructs using noncannulated cortical locking screw was significantly higher than that of the constructs using cannulated locking screws (P=.002). The failure mode observed in all specimens was a permanent screw-bending deformity over the head-shaft junction of proximal metaphyseal screws, irrespective of whether they were cannulated or noncannulated cortical locking screws. Fixation with noncannulated cortical locking screws offered more stability than cannulated locking screws with regard to axial stiffness and failure strength in a porcine model with unstable proximal tibial fractures.

The Ilizarov external fixator--a useful alternative for the treatment of proximal tibial fractures. A prospective observational study of 30 consecutive patients

BACKGROUND

In dislocated proximal tibial fractures, the most frequently used treatment is ORIF with screws and plates. Minimally-invasive techniques using external fixation are an alternative. The aim of this study was to analyse the clinical and radiological results using the Ilizarov technique in both uni- and bicondylar tibial fractures.

METHODS

Thirty consecutive patients with isolated fractures of the proximal tibia were treated with the Ilizarov technique, 11 Schatzker I-IV with 2-3 rings and 19 Schatzker V-VI with 3-4 tibial rings and a femoral, hinged, two-ring extension. Unrestricted weight-bearing was allowed. Pre and post-operatively, conventional radiographs, computerized tomography scans, post-operative pain assessments and complications were evaluated. The knee function was evaluated with the EQ-5D, NHP and KOOS scores, as well as self-appraisal.

RESULTS

All the fractures healed. Twenty-five patients achieved a range of motion better than 10-100º. The type I-IV fractures had a shorter operating time and hospital stay, as well as better knee flexion, and the self-appraisal indicated that they tolerated the treatment better. Pin infections occurred in 4% of the pin sites, but only two patients required debridement. Two patients developed compartment syndrome and underwent fasciotomy. No patient complained of functional knee instability. Two patients underwent a total knee arthroplasty because of residual pain. The overall result was judged as satisfactory in twenty-seven patients.

CONCLUSIONS

The Ilizarov method produces a good clinical outcome and is a valuable treatment alternative in proximal tibial fractures of all types.

Midterm Results of a Combined Biological and Mechanical Approach for the Treatment of a Complex Knee Lesion

OBJECTIVE

Complex fractures of the tibial plateau are difficult to treat and present a high complication rate. The goal of this report is to describe a combined biological and mechanical approach to restore all morphological and functional knee properties.

METHODS

We treated a 50-year-old woman, who was affected by a posttraumatic osteochondral lesion and depression of the lateral tibial plateau with knee valgus deviation. The mechanical axis was corrected with a lateral tibial plateau elevation osteotomy, the damaged joint surface was replaced by a recently developed biomimetic osteochondral scaffold, and a hinged dynamic external fixator was applied to protect the graft and at the same time to allow postoperative joint mobilization.

RESULTS

A marked clinical improvement was documented at 12 months and further improved up to 5 years, with pain-free full range of motion and return to previous activities. The MRI evaluation at 12 and 24 months showed that the implant remained in site with a hyaline-like signal and restoration of the articular surface.

CONCLUSION

This case report describes a combined surgical approach for complex knee lesions that could represent a treatment option to avoid or at least delay posttraumatic osteoarthritis and more invasive procedures.

Management of the Schatzker VI fractures with lateral locked screw plating

Complex proximal tibial plateau fractures need surgical treatment to achieve good clinical results. The treatment of this kind of fractures is often complicated either by the patient's compromised general conditions, or by soft tissue damage. The locking plate combines the technical advantages of an angular stable plate with those of the modern biological plating technique. From December 2002 to December 2008 we treated 18 patients with complex fractures of the tibial plateau (Schatzker VI). All patients were treated with a fixed angle locking plate, 15 with the LISS (Less Invasive Stabilisation System) and 3 with ZPLT (Zimmer Periarticular Locking Plate system). Average time for full weight bearing was 16.2 weeks. In 3 cases we removed the fixation devices after healing because the patients didn't tolerate the fixation devices. Two patients developed superficial infections that we treated with antibiotic therapy. In 2 cases the LISS plate broke because of pseudarthrosis at the diaphyseal level. To conclude, analysing the results we obtained, we consider that the LISS system is an extremely effective fixation device for the treatment of such difficult and complicated fractures as high energy tibial plateau fractures certainly are. Indirect reduction of the fracture, obtained either with an external fixator, or with traction, must precede the use of the fixation device. The failures, such as post-op malalignment or loss of reduction, are due to a wrong evaluation of the fracture morphology. In fact, comminuted fractures, dislocation and rotation of the medial tibial plateau cannot be stabilised just with lateral angular stable plates, but fixation of the medial tibial plateau must be performed first.

High energy tibial plateau fractures treated with hybrid external fixation

Management of high energy intra-articular fractures of the proximal tibia, associated with marked soft-tissue trauma, can be challenging, requiring the combination of accurate reduction and minimal invasive techniques. The purpose of this study was to evaluate whether minimal intervention and hybrid external fixation of such fractures using the Orthofix system provide an acceptable treatment outcome with less complications. Between 2002 and 2006, 33 patients with a median ISS of 14.3 were admitted to our hospital, a level I trauma centre, with a bicondylar tibial plateau fracture. Five of them sustained an open fracture. All patients were treated with a hybrid external fixator. In 19 of them, minimal open reduction and stabilization, by means of cannulated screws, was performed. Mean follow-up was 27 months (range 24 to 36 months). Radiographic evidence of union was observed at 3.4 months (range 3 to 7 months). Time for union was different in patients with closed and grade I open fractures compared to patients with grade II and III open fractures. One non-union (septic) was observed (3.0%), requiring revision surgery. Pin track infection was observed in 3 patients (9.1%).

Compared to previously reported series of conventional open reduction and internal fixation, hybrid external fixation with or without open reduction and minimal internal fixation with the Orthofix system, was associated with satisfactory clinical and radiographic results and limited complications.

Tibial plateau fractures: A review

Tibial plateau fractures are uncommon injuries of the proximal tibia which vary in severity from minimally displaced stable injuries to high energy complex fractures with significant articular and metaphyseal comminution and severe associated soft tissue injuries. Following initial assessment and appropriate investigation a number of management options are available to the treating surgeon. We discuss the presentation, initial management and investigation as well as outlining the various treatment options with an emphasis on operative treatment. We further discuss the common complications and outcomes following tibial plateau fracture.

Surgical approach for high-energy posterior tibial plateau fractures

BACKGROUND

High-energy fractures of posterior tibial plateau always need surgical treatment. Generally, posterior fragments of these fractures could not be exposed and reduced well in conventional anterior approaches. Although a posterolateral/posteromedial approach to manage posterior tibial plateau fractures can achieve satisfactory results, there are few presentations concerning the treatment of these high-energy injuries based on posterior approaches combined with anterior approach if necessary.

MATERIALS AND METHODS

Ten cases of posterior tibial plateau fractures from high-energy injuries were retrospectively reviewed and followed up for mean 26.5 months (range 14-45 months). A posterolateral/posteromedial approach was adopted primarily to fix main fragment in posterior tibial plateau, and intraoperative assessment of the stability of knee was done. An anterior approach was added if required.

RESULTS

Posterolateral approach was employed in seven cases, posteromedial in three, and additional anteromedial in three, and anterolateral in two cases. The average time to union of all 10 fractures was 3.7 months (range 3-5.5 months). Nine patients had satisfactory articular reduction. The range of motion of the knee averaged 2° of extension to 110.5° of flexion. No patient complained of knee instability. The average postoperative HSS score at the final followup was 92.70.

CONCLUSIONS

High-energy fractures of posterior tibial plateau could be well treated based on posterior approaches combined with necessary anterior approach if required.

Tibial plateau fractures: internal fixation with locking plates and the MIPO technique

Proximal tibial fractures are difficult lesions to treat because of the involvement of the articular surface, the often occurring comminution, and the precarious condition of the soft tissues, especially following high-energy trauma. Aim of the treatment is to restore the congruence of the articular surface supporting the tibial plateau cartilage which is usually depressed; to fix the fracture with a stable device; to allow early rehabilitation. We present our treatment strategy, utilising closed or open reduction and internal fixation, angle-stable polyaxial plates, immediate osteointegration, when necessary, with autologous bone graft or other osteoconductive material augmented with autologous platelet gel. Surgery is soft-tissue dependent in terms of timing, and it is usually performed directly or under supervision of an experienced surgeon utilising, whenever possible, a tissue sparing technique. A cohort of 58 proximal tibial fractures, surgically treated, from January 2004 to June 2007, was retrospectively reviewed. Fractures were classified according the OTA/AO classification. The assessment of the functional outcome with the use of the Rasmussen score identified good to excellent results in 78% of the cohort 12 months post-surgery. Internal fixation with locking plates, following the principles of MIPO (Minimally Invasive Percutaneous Osteosynthesis), provides satisfactory fracture reduction with good results regarding the mid-term clinical outcome.

The Ilizarov method of external fixation: current intraoperative concepts

The Ilizarov method of external fixation is used to treat fractures, complex lower extremity deformities, osteomyelitis, and soft tissue contractures and to lengthen limbs. Tremendous improvements in the Ilizarov method have occurred during the past 60 years, improving intraoperative care and limb salvage management concepts. Improved instrumentation has increased the quantity and complexity of the tray systems required for these procedures. Perioperative nurses must be well versed in optimal preparation and function of Ilizarov fixation systems to ensure safe patient care during Ilizarov external fixation procedures.

Functional and radiological evaluations of high-energy tibial plateau fractures treated with double-buttress plate fixation

OBJECTIVE

This study was designed to evaluate the functional and radiological outcomes of patients with complex tibial plateau fractures treated with double-buttress plate fixation.

METHODS

Sixty five cases of complex (Schatzker type V and VI) tibial plateau fractures were treated with double-buttress plate fixation in our centre from September 2001 to September 2006 through two separate plate incisions. Fifty four patients were followed up for a period ranging from 12 to 48 months and evaluated for the functional and radiological outcomes by a series of standard questionnaire and measurement.

RESULTS

Due to the good exposure without any extensive soft-tissue dissection of the double-buttress plate fixation, the fractures in all 54 patients were healed and the treatment achieved greater than 90% of satisfactory-to-excellent rates of reduction. The mean time of bone union was 15.4 weeks (range, 12-30 weeks), and the mean time of full weight-bearing was 18.7 weeks (range, 14-26 weeks). At the final follow-up visit, no patients showed knee instability; the mean range of motion was 107.6 degrees (range, 85 degrees -130 degrees ). For all patients, no statistically significant difference in the functional outcomes was observed between their 6-months and final follow-up visits; or in the radiological findings between their immediate postoperative and final follow-up examinations.

CONCLUSION

Double-buttress plate fixation is a feasible treatment option for bilcondylar and complex tibial plateau fractures. Although technically demanding, it offers reliable stability without additional postoperative adjuvant external fixation, and at the same time avoids extensive soft tissue dissection, allowing the early painless range of motion.
