Intramedullary Nailing with a Suprapatellar Approach and Condylar Bolts for the Treatment of Bicondylar Fractures of the Tibial Plateau

Surgical treatment of ipsilateral bifocal tibial fractures: a challenge for the surgeon

INTRODUCTION

The association of ipsilateral tibia fractures has a low incidence, being up to 3.2% of total tibia fractures. Currently there is no gold standard regarding the ideal surgical treatment. The objective of this study is to analyze the surgical treatment and the radiographic and functional results, as well as the associated complication rate of ipsilateral bifocal tibia fractures.

MATERIAL AND METHODS

Retrospective observational study in our hospital from 2010 to 2022 of 24 patients who underwent bifocal fracture of the ipsilateral tibia. Demographic and surgical data and complications during follow-up were included.

RESULTS

The 24 patients were classified into group 1 when they presented a fracture of the plateau and distal tibia (25%), group 2 with a fracture of the plateau and diaphysis (33%) and group 3 with a fracture of the diaphysis and distal tibia (42%). 3 patients underwent surgery with 1 implant and 21 patients with 2 implants. The average follow-up time in outpatient clinics was 2 and a half years. At one year, 22 patients (92%) had full weight bearing and 2 patients had partial weight bearing (8%) due to the sequelae of the fractures. The average time for consolidation of the diaphysis was 7.75±2 months, with no significant differences observed between group 2 and group 3 (p=0.06). The average time for consolidation of the metaphysis was 3.50±1.5 months, with no significant differences observed between group 1 and group 2 (p=0.065). 7 patients (30%) had complications during follow-up.

CONCLUSIONS

Bifocal tibia fractures can be treated using a combination of intramedullary nailing and plate osteosynthesis with good long-term results, obtaining an optimal union rate and low complications. In addition, it facilitates the reduction of the fracture, thus facilitating the patient's recovery and obtaining good long-term functional results.

Suprapatellar intramedullary nail combined with screw fixation has comparable surgical outcomes to minimally invasive locking plate fixation in ipsilateral tibial plateau and shaft fractures

PURPOSE

To compare union rate, union time, alignment, and complication rate in ipsilateral tibia plateau and shaft fractures treated via suprapatellar intramedullary nailing with screw fixation and minimally invasive locking plate fixation.

MATERIALS AND METHODS

A retrospective study was conducted on 48 patients who underwent minimally invasive plate fixation (n = 35) or suprapatellar intramedullary nailing with screw fixation (n = 13), for the treatment of ipsilateral tibial plateau and shaft fractures with at least 1-year follow-up. Union rate, union time, radiologic alignment, and complication rate such as malalignment, nonunion, and fracture-related infection (FRI) were investigated.

RESULTS

Demographic data were not different between the two groups. Coronal plane alignment was 0.17 ± 4.23 in the plate group and -0.48 ± 4.17 in the intramedullary nail group (p = 0.637). Sagittal plane alignment was -0.13 ± 5.20 in the plate group and -1.50 ± 4.01 in the suprapatellar intramedullary nail group (p = 0.313). Coronal and sagittal malalignment recorded equal results: (p > 0.99), FRI (p = 0.602), nonunion and union times recorded (p = 0.656) and (p = 0.683, 0.829), respectively, and showed no significant difference between the two groups.

CONCLUSION

Suprapatellar intramedullary nailing with screw fixation had similar surgical outcomes with minimally invasive locking plate fixation in ipsilateral tibial plateau and shaft fractures in terms of union rate, union time, alignment, and complication rate. Thus, frequent use of intramedullary nailing combined with screw fixation is anticipated in patients with ipsilateral tibial plateau and shaft fractures when the soft tissue condition is not desirable.

Locking compression plate + T-type steel plate for postoperative weight bearing and functional recovery in complex tibial plateau fractures

BACKGROUND

Complex tibial plateau fractures can seriously affect quality of life and physical and mental health of patients. The anatomical relationship between the proximal tibial bone and soft tissue is complex, resulting in different types of tibial plateau fractures. Violent trauma can lead to displaced fracture, serious soft tissue injury, and potentially, dislocation of the knee joint. Therefore, tibial plateau fractures are extremely unstable.

AIM

To assess the use of locking compression plate (LCP) + T-type steel plate for postoperative weight bearing and functional recovery of complex tibial plateau fractures.

METHODS

Ninety-seven patients with complex tibial plateau fractures who underwent surgery at our hospital were selected for retrospective study. Forty-nine patients had been treated with LCP + T-type steel plate limited internal fixation (study group), and 48 patients with bilateral ordinary steel plate support (control group). The operation process index, postoperative rehabilitation related index, Rasmussen score of the knee joint, tibial plateau varus angle (TPA), tibial plateau retroversion angle (PA), and surgical complications of the two groups were compared.

RESULTS

The operation time and intraoperative bone graft volume in the study group were lower than those in the control group (P < 0.05). There were no significant differences in surgical bleeding, anterior external incision length, postoperative drainage, hospital stay duration, and fracture healing time between the groups (P > 0.05). There was no significant difference in the TPA and PA angle between the groups immediately and 18 mo after surgery (P > 0.05). At 12 mo after surgery, the Rasmussen scale score was higher in the study group than in the control group (P < 0.05). There was no significant difference in the Rasmussen scale score at 18 mo after surgery, and the radiology score at 12 and 18 mo after surgery, between the two groups (P > 0.05). The postoperative complication rate in the study group (3.77%) was lower than that in the control group (15.09%; P < 0.05).

CONCLUSION

LCP + T-type steel plate internal fixation has advantages in terms of minimizing trauma and enabling early postoperative functional exercise, promoting functional recovery and lower limb weight-bearing, and reducing postoperative complications.

Systematic review assessing the evidence for the use of stem cells in fracture healing

AIMS

Bone demonstrates good healing capacity, with a variety of strategies being utilized to enhance this healing. One potential strategy that has been suggested is the use of stem cells to accelerate healing.

METHODS

The following databases were searched: MEDLINE, CENTRAL, EMBASE, Cochrane Database of Systematic Reviews, WHO-ICTRP, ClinicalTrials.gov, as well as reference checking of included studies. The inclusion criteria for the study were: population (any adults who have sustained a fracture, not including those with pre-existing bone defects); intervention (use of stem cells from any source in the fracture site by any mechanism); and control (fracture healing without the use of stem cells). Studies without a comparator were also included. The outcome was any reported outcomes. The study design was randomized controlled trials, non-randomized or observational studies, and case series.

RESULTS

In all, 94 eligible studies were identified. The clinical and methodological aspects of the studies were too heterogeneous for a meta-analysis to be undertaken. A narrative synthesis examined study characteristics, stem cell methods (source, aspiration, concentration, and application) and outcomes.

CONCLUSION

Insufficient high-quality evidence is available to determine the efficacy of stem cells for fracture healing. The studies were heterogeneous in population, methods, and outcomes. Work to address these issues and establish standards for future research should be undertaken.Cite this article: Bone Joint Open 2020;1-10:628-638.

Establishment of Classification of Tibial Plateau Fracture Associated with Proximal Fibular Fracture

OBJECTIVE

The purpose of this retrospective study was to determine the incidence of fibular fractures as an associated injury in tibial plateau fractures according to CT scan. We also attempt to introduce a new morphological sub-classification on this associated injury and to analyze the correlation between this classification and tibial plateau fractures.

METHODS

We selected cases with fibular fractures from all the tibial plateau fracture patients. The cases were further divided into 2 groups: unicondylar group and bicondylar group. On the basis of our new classification system of fibular fracture, all the included cases were divided into 5 subgroups.

RESULTS

Finally, a total of 150 cases associated with fibular fractures in 502 tibial plateau fracture cases were identified from our institution database. The incidence of fibular head fracture in tibial plateau fractures was 29.88% (150/502). Seventy-one cases (47.3%) were involved one condyle, and 79 cases (52.7%) involved both. It shows significant difference in the subgroup of avulsion fracture with horizontal fracture line (Type A) which is ratio of 16.9% in unicondylar group and 1.27% in bicondylar group.

CONCLUSION

A new classification of this associated injury describing the morphology of the fracture fragments may improve operative planning.
