Management of distal third tibial fractures: comparison of combined internal and external fixation with minimally invasive percutaneous plate osteosynthesis

External fixator combined with three different fixation methods of fibula for treatment of extra-articular open fractures of distal tibia and fibula: a retrospective study

Background

To compare the efficacy of three different fixation methods of fibula combined with external fixation of tibia for the treatment of extra-articular open fractures of distal tibia and fibula.

Methods

From January 2017 to July 2019, 91 cases of open fractures of distal tibia and fibula were treated with external fixator, and the fibula was fixed with non-fixation (group A, n = 35), plate-screw (group B, n = 30) and Kirschner wire (group C, n = 26). The operation time, intraoperative blood loss, surgical and implants costs, fracture healing time, postoperative complications, and American Orthopaedic Foot and Ankle surgery (AOFAS) scores were compared among the groups.

Results

Four patients were lost to follow-up, and 87 patients were followed up for 5–35 months (average, 14.2 months). The operation time of group C (114.92 ± 36.09 min) was shorter than that of group A (142.27 ± 47.05 min) and group B (184.00 ± 48.56 min) (P < 0.05). There was no difference in intraoperative blood loss among the three groups (P > 0.05). The surgical and implants costs in group C (5.24 ± 1.21, thousand dollars) is lower than that in group A (6.48 ± 1.11, thousand dollars) and group B (9.37 ± 2.16, thousand dollars) (P < 0.05). The fracture healing time of group C (5.67 ± 1.42 months) was significantly less than that of group A (6.90 ± 1.33 months) and group B (6.70 ± 1.12 months) (P < 0.05). The postoperative complications such as fractures delayed union and nonunion in group C (2 cases, 8.00%) is less than that in group A (13 cases, 39.39%) and group B (11cases, 37.93%) (P < 0.05). The wound infection and needle-tract infection did not differ among the three groups (P > 0.05). The excellent or good rate of ankle function was 69.70% in group A, 72.41% in group B and 84.00% in group C, with no statistical difference among the three groups (P > 0.05).

Conclusion

Compared with simple external fixator fixation and external fixator combined with plate-screw osteosynthesis, external fixator combined with K-wire intramedullary fixation shortens the operative time and fracture healing time, reduced costs and complications of fracture healing, while the blood loss, infection complications and ankle function recovery showed no difference with the other two groups. External fixator combined with plate-screw osteosynthesis had no advantage in treating extra-articular open fractures of distal tibia and fibula when compared with simple external fixation.

Minimally invasive percutaneous plates versus conventional fixation techniques for distal tibial fractures: A meta-analysis

OBJECTIVE

This meta-analysis was performed to determine the effects of minimally invasive percutaneous plate osteosynthesis (MIPO) versus conventional fixation techniques (CFT) for treating distal tibial fractures.

METHODS

A literature search was performed in EMBASE, Medline, the Cochrane Library, and Web of Science. The trials searched were evaluated for eligibility. The Cochrane Collaboration's Review Manager software was used to perform meta-analyses.

RESULTS

Eight studies were enrolled, including five randomized controlled trials, one control-matched trial and two retrospective cohort trials. The meta-analysis revealed that MIPO has a longer operating time, longer radiation time and higher incidence rate of soft tissue irritation symptoms than those of CFT. There was no significant difference between the two techniques with regard to union time, the American Orthopedic Foot and Ankle Society (AOFAS), infection rate and various other complications.

CONCLUSIONS

The present meta-analysis showed that MIPO did not have obvious advantages over CFT in the treatment of distal tibia fracture. However, more rigorous randomized controlled trials are required in the future.

Definitive Management of Distal Tibia and Simple Plafond Fractures With Circular External Fixation

Obtaining optimal results in the treatment of extraarticular distal tibia fractures can be challenging. Plate and screw and intramedullary fixation have proven to be effective treatments, but are associated with significant complication rates when used for open fractures and patient with severe medical comorbidities. External fixation is a third alternative that is less often employed, but provides a very effective means of treatment. Circular external fixation offers great flexibility in obtaining anatomic alignment and stable fixation for even the most challenging distal tibia fractures. In addition, it provides advantages in limiting the risk of deep infection, dealing with bone loss, and obtaining soft tissue coverage. The greater ease of treatment and potential economic advantage in patient cohorts with low complication rates, such as closed fractures, supports the preferential use of internal fixation. However, circular external fixation may be the preferred treatment for patients with higher-grade open fractures, a poor soft tissue envelope with limited fixation options distally, and major comorbidities (diabetes, immune deficiency) with an associated high risk of complications.

Surgical interventions for treating distal tibial metaphyseal fractures in adults

BACKGROUND

The distal tibial metaphysis is located in the lower (distal) part of the tibia (shin bone). Fractures of this part of the tibia are most commonly due to a high energy injury in young men and to osteoporosis in older women. The optimal methods of surgical intervention for a distal tibial metaphyseal fracture remain uncertain.

OBJECTIVES

To assess the effects (benefits and harms) of surgical interventions for distal tibial metaphyseal fractures in adults. We planned to compare surgical versus non-surgical (conservative) treatment, and different methods of surgical intervention.

SEARCH METHODS

We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (9 December 2014), the Cochrane Central Register of Controlled Trials (2014, Issue 12), MEDLINE (1946 to November Week 3 2014), EMBASE (1980 to 2014 Week 48), the Airiti Library (1967 to 2014 Week 8), China Knowledge Resource Integrated Database (1915 to 2014 Week 8), ClinicalTrials.gov (February 2014) and reference lists of included studies.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled clinical studies comparing surgical versus non-surgical (conservative) treatment or different surgical interventions for treating distal tibial metaphyseal fractures in adults. Our primary outcomes were patient-reported function and the need for secondary or revision surgery or substantive physiotherapy because of adverse outcomes.

DATA COLLECTION AND ANALYSIS

Two authors independently selected studies, assessed the risk of bias in each study and extracted data. We resolved disagreement by discussion and, where necessary, in consultation with a third author. Where appropriate we pooled data using the fixed-effect model.

MAIN RESULTS

We included three randomised trials that evaluated intramedullary nailing versus plating in 213 participants, with useable data from 173 participants of whom 112 were male. The mean age of participants in individual studies ranged from 41 to 44 years. There were no trials comparing surgery with non-surgical treatment. The three included trials were at high risk of performance bias, with one trial also being at high risk of selection, detection and attrition bias. Overall, the quality of available evidence was rated as very low for all outcomes, meaning that we are very unsure about the estimates for all outcomes.The results of two large ongoing trials of nailing versus plating are likely to provide sufficient evidence to address this issue in a future update.

AUTHORS' CONCLUSIONS

Overall, there is either no or insufficient evidence to draw definitive conclusions on the use of surgery or the best surgical intervention for distal tibial metaphyseal fractures in adults. The available evidence, which is of very low quality, found no clinically important differences in function or pain, and did not confirm a difference in the need for re-operation or risk of complications between nailing and plating.The addition of evidence from two ongoing trials of nailing versus plating should inform this question in future updates. Further randomised trials are warranted on other issues, but should be preceded by research to identify priority questions.

Open unstable metaphyseo-diaphyseal fractures of the tibia in adolescents: treatment by flexible intramedullary nails augmented by external fixator

INTRODUCTION

The treatment of open and unstable metaphyseo-diaphyseal fractures of the tibia in adolescents is challenging. It is important to choose a fixation method that can maintain alignment, allow wound care and not violate the growth plate. The aim of this work was to evaluate the efficacy of using flexible intramedullary nails (FIN) augmented by external fixator (EF) in the management of such fractures.

PATIENTS AND METHODS

A total of 26 males, with a mean age of 14.08 years and average body weight of 49.8 kg, presented with open metaphyseo-diaphyseal tibial fractures. All cases were treated using FIN augmented by mono-lateral EF. The fractures were located at the upper third in 17 cases and at the lower third in nine cases. The fracture pattern was spiral in eight cases, oblique in seven and multi-fragmentary in 11. The results were evaluated according to the scoring system for femoral TENs.

RESULTS

All fractures united primarily after an average eight to 12 weeks with no evident angular deformity or limb-length discrepancy. None of the cases required cast immobilization or revision procedure. Twenty patients had excellent results, six patients showed good results and none had poor results. Fracture characteristics as well as patients' characteristics had no statistically significant effect (p > 0.005) on the final end results.

CONCLUSIONS

The use of FIN augmented by EF is a good alternative in the management of open metaphyseo-diaphyseal tibial fractures in adolescents. This fixation provides more stability, allows easy access to the wound and early patients' ambulation.
