One in Three of Pediatric Tibia Shaft Fractures is Currently Treated Operatively: A 6-Year Epidemiological Study in two University Hospitals in Finland Treatment of Pediatric Tibia Shaft Fractures

Management of Pediatric Type III Tibial Shaft Fractures: A Cohort Study Utilizing the Trauma Quality Improvement Program Database

BACKGROUND

Pediatric open tibial fractures represent a challenging subset of injuries with limited literature to guide management. For children, the epidemiology, management, and outcomes of tibial-shaft fractures have not been fully described.

METHODS

A retrospective analysis of the Trauma Quality Improvement Program Data Bank from 2017-2020 was used to query demographics, injury patterns, and management strategies in pediatric open tibial fractures. Fractures were compared by age group (0-5, 6-12, 13-17 years) and type (I/II vs type III). A subgroup analysis was performed on patients with type III open fractures.

RESULTS

A total of 3480 open tibial fractures were identified, 3049 were type I/II, and 431 were type III. Motor vehicle accidents (48%) were the most common mechanism of injury (P < 0.001). Subanalysis of 128 type IIIb/c tibial fractures revealed local flap reconstruction (25%) skin graft (25%), and free tissue transfer were the most common management strategies and soft-tissue coverage was achieved after 162 hours (interquartile range = 109-231). Negative pressure wound therapy was utilized in 63% of cases but used in isolation in only 23% of cases. Immediate fixation with intramedullary nailing was more frequently used in the 13-17 age group while plate fixation was more commonly used in younger age groups.

CONCLUSIONS

Soft-tissue management patterns following open tibial shaft fractures mirror those seen in adult cohorts. The median time to achieve soft-tissue coverage exceeds the traditional 72-hour target advocated by Godina. Age-based variation is seen in orthopedic management of these fractures based on growth maintenance concerns.

Tibial shaft fractures in children: flexible intramedullary nailing in growing children especially weighing 50 kg (110 lbs) or more

Currently the gold standard in surgical treatment of displaced tibial shaft fractures in children with open growth cartilage is elastic stable intramedullary nailing (ESIN). The purpose of this study is the analysis of indications, complications, and duration of treatment using intramedullary flexible nails in children who are still growing but especially weighing 50 kg or more. Hospital records from 2017 to 2020 were retrospectively reviewed to identify the children from 4 to 17 years of age with displaced tibial shaft fractures admitted to the hospital. Only children with open growth cartilage, with a minimum of 6 months of follow-up and complete clinical data, were included. Studies of 91 children xwere analyzed. The average patient age at the time of the injury was 10.88 ± 2.82 years. In the entire group, 31.9% children weighed 50 kg or more, and 68.1% of the children were below this weight. All children were treated using ESIN. The mean time to nail removal was 8.4 ± 4.09 months in the whole group of children stabilized with ESIN. There were no differences in the two groups depending on the weight ( P = 0.637). Only two adverse events were observed. This study demonstrates that the use of ESIN in displaced tibial shaft fractures in growing children weighing 50 kg or more is acceptable and safe. The discussion to be made is whether it is still an acceptable method of treatment for this type of fracture due to the progressive obesity epidemic in children and adolescents.

Child Fractures: Are We Getting More Surgical?

Historically, surgeries on the immature skeleton were reserved for open or articular fractures. In recent years, the improvement in the quality and safety of anesthesia, new imaging equipment, implants designed especially for pediatric fractures, associated with the possibility of shorter hospitalization time and rapid return to social life has demonstrated a new tendency to evaluate and treat fractures in children. The purpose of this update article is to answer the following questions: (1) Are we really turning more surgical in addressing fractures in children? (2) If this is true, is this surgical conduct based on scientific evidence? In fact, in recent decades, the medical literature demonstrates articles that support better evolution of fractures in children with surgical treatment. In the upper limbs, this is very evident in the systematization of the reduction and percutaneous fixation of supracondylar fractures of the humerus and fractures of the forearm bones. In the lower limbs, the same occurs with diaphyseal fractures of the femur and tibia. However, there are gaps in the literature. The available published studies show low scientific evidence. Thus, it can be inferred that, even though the surgical approach is more present, the treatment of pediatric fractures should always be individualized and conducted according to the knowledge and experience of the professional physician, taking into account the presence of technological resources available for the care of the small patient. All possibilities, non-surgical and/or surgical, should be included, always instituting actions based on science and in agreement with the family's wishes.

Elastic Stable Intramedullary Nailing for Treatment of Pediatric Tibial Fractures: A 20-Year Single Center Experience of 132 Cases

Objective: The aim of this study was to analyze the outcomes and complications in children treated with elastic stable intramedullary nailing (ESIN) for tibial fractures. Methods: The study included 132 patients (92 males) with a median age of 11 years (IQR 10, 15) treated with ESIN for displaced tibial shaft fractures or dia-metaphyseal distal tibial fractures from March 2002 to March 2022. The median follow-up was 118.5 months (IQR 74.5, 170). The primary outcome was success rate, while secondary outcomes were the time of bone healing, length of hospital stay, and associated injuries. Demographic data, type and nature of fracture, indication for surgery, healing time, operative time, complications of treatment, and time to implant removal were recorded. Results: Complete radiographic healing was achieved at a median of 7 weeks (IQR 6, 9). Most of the patients (n = 111; 84.1%) had fractures localized in the shaft of the tibia. The most common injuries were acquired by road traffic accidents (n = 42) and by a fall in the same level (n = 29), followed by injuries from sport activities (n = 21) or motorbike accidents (n = 18). Associated injuries were reported in 37 (28%) children. Fractures were closed in the majority of the children (n = 100; 76%), while 32 (24%) children presented with an open fracture. Children with open fractures were significantly older than children with closed fractures (13.5 years (IQR 10, 15) vs. 11 years (IQR 8.5, 14.5); p = 0.031). Furthermore, children with open fractures had a significantly longer hospital stay (7 days (IQR 5, 9) vs. 3 days (IQR 3, 6); p = 0.001), a higher rate of associated injuries (n = 14 (43.7%) vs. n = 23 (23%); p = 0.022), and a higher rate of postoperative complications (n = 7 (21.9%) vs. n = 8 (8%); p = 0.031). No intraoperative complications were recorded. A total of 15 (11.4%) postoperative complications were recorded. Most complications (60%) were minor complications, mostly related to the wound at the nail insertion site and were managed conservatively. A total of six (4.5%) patients required reoperation due to angulation of the fragments (n = 5) or refracture (n = 1). Conclusion: ESIN is a minimally invasive bone surgery technique and is a highly effective treatment for pediatric tibial unstable fractures with a low rate of complications. Based on the given results, surgical stabilization of the tibial fractures using titanium intramedullary nailing can be safely performed without casting with early physiotherapy.

Modern management of paediatric tibial shaft fractures: an evidence-based update

AIMS

This review provides a summary of recent evidence surrounding the treatment of paediatric tibial shaft fractures and presents an algorithm to aid management of these injuries. This article reviews the relevant anatomy, epidemiology and aetiology of tibial shaft fractures and summarises contemporary treatment principles. Management recommendations and supporting evidence are given for fractures according to age (< 18 months, 18 months-5 years, 6-12 years, and 13-18 years). The relative merits of casting, plate fixation, elastic and rigid intramedullary nailing, and external fixation are discussed. Special attention is paid to the management of open tibial shaft fractures and to complications including infection and acute compartment syndrome.

CONCLUSIONS

There has been a shift away from non-operative management of paediatric tibial shaft fractures over the last 30 years. However, recent evidence highlights that a non-operative approach produces acceptable outcomes when used in simple closed fractures at any age. Operative management may be indicated for unstable fractures where satisfactory alignment cannot be maintained or in specific circumstances including open injuries and polytrauma. Open injuries require urgent assessment by a combined orthopaedic and plastic surgery team at a specialist tertiary centre.

Physeal-Sparing Rigid Intramedullary Nailing in Adolescent Tibial Shaft Fractures: A Pilot Study

Purpose: Elastic stable intramedullary nailing (ESIN) and open reduction internal fixation (ORIF) are literature-supported operative treatments for displaced tibial shaft fractures in skeletally immature patients. Very little is written about rigid intramedullary nails (RIMNs) in adolescents. Our purpose is to describe a physeal-sparing, reamed, locked RIMN technique for adolescent tibial shaft fractures and report its safety.

Methods: Adolescent patients with tibial shaft fractures indicated for operative intervention at one institution were retrospectively identified from 2011-2018. Patients were classified based on method of fracture fixation. Primary outcomes included fracture union, reoperation, and complication rates.

Results: Thirteen patients were included in the RIMN arm, with an average age of 13.8 years. Two patients in the observational group underwent ESIN and seven patients underwent ORIF, with an average age of 11.5 years. Significant differences were found between time of immobilization (28 days vs 121 days), time to touch down weight bearing release (1 day vs 34 days), and hardware pain (2/13 vs 7/9). The RIMN group sustained fewer reoperations (2/13 vs 5/9). No differences were found in rates of complications or fixation failure between groups.

Conclusions: Based on our small pilot study, RIMNs in adolescents should be considered as a potential treatment option when a physeal-sparing distal start point is utilized. Additionally, short-term follow-up suggests safety. Patients who underwent the RIMN procedure required fewer reoperations compared with the observational group. Overall, fracture healing was similar across the two groups. The benefits of RIMN include early immobilization and improved weight-bearing profile.

Lower Leg Fractures in Children and Adolescents-Comparison of Conservative vs. ECMES Treatment

Background: Lower leg fractures are one of the most common fractures in pediatric age. In general, treatment of lower leg fractures is predominantly non-operative, requiring clinical and radiological controls. Nevertheless, it can be observed that in recent years tibial shaft fractures have increasingly been treated surgically. The aim of the present study is to investigate treatment strategies in the context of different fracture types of the lower leg. Methods: In this retrospective chart review, we analyzed 168 children with a diaphyseal fracture of the lower leg admitted to a trauma center between 2005 and 2017. The fractures were classified according to the AO Pediatric Comprehensive Classification of Long Bone Fractures (AO-PCCF). Results: The frequency of fractures based on the AO-PCCF classification was as follows: Simple oblique fracture of the tibia (43.5%, n = 73), hereof 32 toddler's fractures, multifragmentary oblique fracture of the tibia in 14.3% (n = 24) and simple oblique fracture of both, tibia and fibula in 18 patients (10.7%). Most pediatric fractures were treated conservatively by cast (n = 125). Thirty-seven patients received an ECMES, whereas 3 patients were treated with an external fixator and also 3 fractures were stabilized by plate osteosynthesis. Conservatively treated patients were significantly younger (mean age 6.0) compared to patients treated with ECMES (mean age 10.2) or plate osteosynthesis (PO)/external fixator (EF) (mean age 11.3), even if toddler's fractures (mean age 2.0) are excluded (mean age 7.4). There was no difference in time to full weight-bearing, hospitalization of patients treated with ECMES compared to conservative therapy although ECMES-treated fractures show more instability. The consolidation time was significantly higher in ECMES treated patients compared to conservative therapy. Conclusion: Pediatric patients (≤4 years) with lower leg fractures most often showed simple oblique fractures of the tibia, half of them toddler's fractures, which were treated predominantly by conservative therapy. All in all, the consolidation time was longer in intramedullary nailing (ECMES) than in conservative therapy. Nevertheless, time to full weight bearing and duration of cast was the same in both groups, even though ECMES treated fractures show more instability.

Treatment of Closed Tibia Shaft Fractures in Children: A Systematic Review and Meta-Analysis

Tibia fractures are among the most common long-bone fractures in children. Despite this, there is no current consensus on the optimal treatment strategy for closed displaced tibia shaft fractures in the pediatric patient population. The aim of this study is to compare the reported complications and outcomes of reduction and cast immobilization versus flexible intramedullary nailing in the treatment of pediatric tibia shaft fractures. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement when conducting and reporting this prospectively registered systematic review. Eleven studies were included. Quality of the studies was assessed using the Coleman methodology score. Mantel-Haenszel cumulative odds ratios were used to compare the risk of complication between different methods of treatment. Eleven studies including 1,083 patients with diaphyseal fractures of the tibia met the inclusion criteria. The most common fracture type was simple 42-A (782; 91%). Majority (75%) of the patients were treated nonoperatively. The total complication rate was higher among operatively treated patients (24 vs. 9%; p < 0.05). Satisfactory fracture alignment had to be restored surgically in 5% of the primarily nonoperatively treated patients. The evidence levels of the included studies were II (1), III (2), and IV (7). Three-fourths of closed diaphyseal fractures of the tibia in children are still treated with reduction and cast immobilization. Flexible intramedullary nailing is associated with significantly higher complication rate than nonoperative treatment.

Intramedullary Nailing of Paediatric Tibial Fractures: Comparison between Flexible and Rigid Nails

PURPOSE

To describe patient characteristics and to compare outcomes of children undergoing rigid intramedullary nailing of tibial fractures as compared with those operated on using elastic intramedullary nailing.

METHODS

A retrospective review of 26 children who have undergone flexible intramedullary nailing of tibial fractures and 30 children with rigid nailing at our university hospital between 2008 and 2017. The patient charts and radiographs were evaluated to identify demographic characteristics and several variables were measured preoperatively, as well as 6-12 weeks postoperatively in addition to final follow-up radiographs.

RESULTS

Twenty-six patients (26/26, 100%) treated with a flexible nail and 14 patients (14/30, 46.7%) treated with a rigid nail had open proximal tibial physis (p < 0.001). An acceptable postoperative alignment was obtained in 20 patients (20/26, 76.9%) in the elastic stable intramedullary nail group and in 29 patients (29/30, 96.7%) in the rigid group (p = 0.026). Some complications occurred in four patients (4/26, 15%) in the elastic stable intramedullary nail population and seven patients (7/30, 23%) in the rigid intramedullary nail population (p = 0.46). Malunion occurred in six patients (6/26, 23%) in the elastic stable intramedullary nail group and in none of the patients treated with a rigid intramedullary nail (p = 0.005).

CONCLUSION

Younger children with tibial fractures who weight 50 kg or less and with proximal tibial growth plates wide open can be treated with elastic stable intramedullary nail while more mature adolescents benefit from rigid intramedullary nailing.

Open Reduction of Closed Pediatric Tibial Shaft Fractures Treated With Intramedullary Stabilization Does Not Increase Risk of Postoperative Complications

OBJECTIVE

To compare union and complication rates in pediatric patients presenting with tibial shaft fractures treated with closed or open reduction before intramedullary stabilization.

DESIGN

Retrospective review.

SETTING

Multiple pediatric trauma centers.

PATIENTS

Pediatric patients presenting with tibial shaft fractures treated with intramedullary stabilization.

INTERVENTION

Intramedullary stabilization after closed or open reduction (percutaneous and open approach).

MAIN OUTCOME MEASURES

Union rates, infection rate (superficial and deep), and unplanned return to the operating room (OR).

RESULTS

One hundred sixty-six patients were included in this study. One hundred thirty-six patients presented with closed fractures, and 30 patients presented with open tibial shaft fractures. Thirty-seven of the 136 patients (27%) with closed fractures had their fracture specifically opened during surgical fixation. There was no statistical difference in radiographic union at 6 months between fractures electively opened and those treated with closed reduction alone 97% versus 98% (P = 0.9). No patient who underwent an open reduction developed infections or wound-healing concerns, whereas 2 of the 99 (2%) patients treated closed had superficial surgical site infections requiring additional treatment (P = 0.999). There was no difference in unplanned return to OR between those who underwent open reduction at the time of intramedullary stabilization (P = 0.568).

CONCLUSION

Performing an open reduction in a closed pediatric tibial shaft fracture before intramedullary fixation does not increase the risk of surgical site infections or wound issues, delayed union, or unplanned return to the OR. An open reduction of a closed tibial shaft fracture for purposes of improving a reduction before intramedullary stabilization may be a safe and effective clinical practice.

Tendency towards operative treatment is increasing in children's fractures: results obtained from patient databases, causes, impact of evidence-based medicine

Results of numerous studies assessing the national or the local patient databases in several countries have indicated that the overall rate of operative treatment in fractures, as well as the rate in certain upper and lower limb fractures, has significantly increased in children. The most prominent increase in the rate of operative treatment was observed in forearm shaft fractures.

Results of several survey studies have revealed that there was not a high level of agreement among paediatric orthopaedic surgeons concerning treatment preferences for several children’s fractures.

The reasons for the increasing tendency towards operative treatment are multifactorial and patient-, parent- and surgeon-dependent factors as well as technological, economic, social, environmental and legal factors seem to have an impact on this trend.

It is obvious that evidence-based medicine is not the only factor that leads to this tendency. A high level of scientific evidence is currently lacking to support the statement that operative treatment really leads to better long-term outcomes in children’s fractures. Properly designed multicentre clinical trials are needed to determine the best treatment options in many fractures in children.

Epidemiology of paediatric lower extremity fractures in a tertiary care center in Switzerland

PURPOSE

About 20% of all fractures in children occur at the lower extremity. This study aims to investigate the epidemiology and injury pattern of lower extremity fractures within the pediatric population consulting a tertiary referral hospital in Switzerland.

METHODS

Study population included all patients up to 16 years presenting with a lower extremity fracture over a period of one year. Recorded data were age, gender, side, season of the year, mechanism, type of fracture and applied treatment.

RESULTS

Fractures of the lower extremity represent 23% of all fractures with a mean age of 9 years and 6 months. The tibia, with 94 fractures (38%), represents the most frequently injured bone. Peak incidence is seen in winter and 24% of tibia shaft fractures were due to board sports. Overall, 82% of fractures were treated by cast with or without closed reduction, and only 18% requested surgery.

CONCLUSION

Board sports seems to be a leading cause of tibial shaft fracture in our region. Nevertheless, only 18% of fractures had recourse to an orthopedic surgeon, hence the importance of the teaching quality of pediatric residents for conservative fracture treatment.

AI. Increasing rates of surgical treatment for paediatric tibial shaft fractures: a national database study from between 2000 and 2012

PURPOSE

Tibia fractures are the third most common long bone fracture in children. Because of the remodelling potential of the tibial diaphysis, nonoperative treatment has historically been advocated for most tibial shaft fractures in children. The purpose of this study was to estimate the rate of surgical treatment of tibial shaft fractures over time and identify demographic factors associated with surgical treatment, utilizing a large, publicly available, national database.

METHODS

The Healthcare Cost and Utilization Project Kids' Inpatient Database was evaluated for the years between 2000 and 2012. Tibial shaft fractures and surgically treated patients were identified using International Classification of Diseases, 9th Revision, Clinical Modification codes. Univariable and multivariable logistic regression were used to determine variables associated with a greater proportion of surgical treatment. Statistical analyses were performed utilizing SAS statistical software v.9.4. Statistical significance was set at p < 0.05.

RESULTS

In all, 24 166 tibial shaft fracture admissions were identified, with 15 621 (64.7%) treated surgically. The percentage of patients receiving surgery to treat tibial shaft fractures increased from 57.3% in 2000 to 74.3% in 2012 (p < 0.001). Multivariable regression showed that increasing age was associated with increased rate of surgical treatment (p < 0.001). The greatest increase in surgical treatment was seen in children aged five to nine years, increasing from 23.0% in 2000 to 46.2% in 2012.

CONCLUSION

The rate of operative treatment of paediatric tibial shaft fractures increased over time. The largest increase was seen in children aged five to nine years. Increased proportion of surgical treatment was associated with older age, concurrent femur fracture and non-Medicaid insurance status.

LEVEL OF EVIDENCE

Level III - Retrospective comparative study.

Evidence-based update on the surgical treatment of pediatric tibial shaft fractures

PURPOSE OF REVIEW

To describe surgical treatment options for pediatric tibial shaft fractures which are the third most common pediatric long bone fracture. Management of these injuries is dictated by fracture location, fracture pattern, associated injuries, skeletal maturity, and other patient-specific factors. Although most pediatric tibial shaft fractures can be treated nonoperatively, this review provides an update on surgical treatment options when operative intervention is indicated.

RECENT FINDINGS

Advances in surgical implants and techniques affords a wide range of options for the surgical treatment of pediatric tibial shaft fractures. Flexible intramedullary nailing is gaining wide adoption for acute surgical treatment. Recent studies support cross-sectional imaging for further evaluation and scrutiny of fracture patterns suspicious for intraphyseal or intra-articular extension. Grade I open tibial shaft fractures may be safely treated with irrigation and debridement in the emergency department; however, no high-level comparative studies have been performed to make any definitive conclusions regarding the effectiveness of this treatment strategy.

SUMMARY

Tibial shaft fractures are common injuries in pediatric patients. Management is dictated by fracture location, fracture pattern, associated injuries, patient age, and other patient-specific factors. Surgical intervention is indicated for fractures that are open, irreducible, have failed nonoperative management, are associated with compartment syndrome, or in the multiply injured patient. Surgical treatment options include flexible intramedullary nailing, plate osteosynthesis, external fixation, and rigid intramedullary nailing. Recent literature has shown increased rates of flexible intramedullary nailing. All operative and nonoperative management options can result in complications including compartment syndrome, infection, delayed union, nonunion, malunion, limb length discrepancy, and symptomatic hardware. Most pediatric patients go on to uneventful union with excellent final outcomes and return to full activities.
