Femoral fractures in the immature skeleton: Characterization, risk factors, and treatment options in a developing country

INTRODUCTION

Femur fracture is one of the most frequent reasons for admission to paediatric trauma units and has a bimodal incidence. The trauma mechanism varies according to the patient's age. Non-operative treatment continues to be performed, although surgical treatment has gained popularity in recent years. Paediatric orthopaedic traumatologists should always bear in mind the already known general principles of treatment. In this study, we aimed to provide a general characterization of femoral fractures, risk factors, and current definitive treatment methods in a developing Latin American country.

MATERIALS AND METHODS

This is an observational, analytical, retrospective study with a non-probabilistic sample of consecutive cases of skeletally immature patients with femoral fractures treated at a trauma hospital in Asunción, Paraguay, from January to December 2022. Patients with diseases fragile bones and femoral fractures were excluded. Demographic and clinical characteristics of the study population were analysed.

RESULTS

Traffic accidents were the most frequent cause of femoral fractures in our population. Femur fractures were more common in males. The femoral shaft was the most frequent fracture site. Age was one of the most important criteria for defining the treatment approach, considering non-operative management in children younger than 4 years.

CONCLUSIONS

Fracture of the femoral shaft in male patients is the most frequent presentation at our Institution. Summer vacations and traffic accidents are the main risk factors identified in Paraguayan children who suffer a femoral fracture. Non-operative treatment is preferred in children under 4 years of age, while surgical treatment is preferred in children aged 5 years and above. Paediatric orthopaedic traumatologists should be involved in parent education to promote children's safety, especially by increasing care and vigilance during school vacations and dangers related to traffic accidents.

Results after skin traction for femur shaft fractures in children below the age of four years

Purpose

Nonsurgical management has been identified as the treatment of choice for femoral shaft fractures in children below four years of age. For various reasons, the surgical approach has become increasingly popular in recent years. The aim of this study is to report results after vertical skin traction and analyze the benefits of this technique as well as to point out advantages compared with surgery in this age group.

Methods

The authors performed a retrospective data analysis, including all patients with femoral shaft fractures below the age of four who were treated with vertical skin traction at our institution between January 2006 and December 2016.

Results

Skin traction for a femoral shaft fracture was performed for 36 patients (mean age 1.6 years; 1 day–3.5 years). The mean duration of traction was 18.5 days (14–30). Complications included soft tissue affections (n = 5), which all healed spontaneously. Consolidation was observed in all fractures. Initial axial deviations and shortening did not change during traction until consolidation (p > 0.05), and no relevant torsion deformity occurred (p = 0.01). Patients gained full weight-bearing within 12.3 days (7–40) following end of traction. At the final follow-up, after a mean of 29.3 months (12–192), leg-length discrepancy (mean 7.1 mm; 5–20) was found on radiograms in nine cases, and axial deviations (mean 7.7°; 5–25) were documented in seven cases. None of the patients had limitations in daily activities or sports.

Conclusion

Skin traction is a technically easy, safe, and non-invasive treatment modality for femoral shaft fractures in children below the age of four years. Strong results are obtained benefited from a high potential of growth-related correction, and in principle no anesthesia is needed. A prolonged hospitalization and socio-economic factors maintain the ongoing debate in comparison with the surgical approach.

[Diaphyseal and metaphyseal femoral fractures in childhood]

Femoral fractures in childhood are rare and are usually the result of severe trauma. Conservative treatment (overhead extension, hip spica cast) can be used in children up to 3 years of age and beyond that elastic stable intramedullary nailing (ESIN) is the method of choice. The prognosis is very good if the surgical technique is adequate. In adolescents > 50 kg in body weight solid nails implanted via the greater trochanter are an alternative (adolescent lateral femoral nail, ALFN). External fixators and plate osteosynthesis are indicated in special situations. Femoral neck fractures are very seldom seen in this age group. Besides Kirschner (K)-wires and screw osteosynthesis a special pediatric hip plate is available in this situation. In the distal metaphysis mostly stable fractures occur in disabled children, which can usually be treated conservatively. In addition, pathological fractures occur in juvenile bone cysts and complex injuries in adolescents, which need stabilization by descending ESIN or with plates. At the distal growth plate relevant growth disturbances are possible.

TREATMENT OF PEDIATRIC FEMORAL FRACTURES IN THE CITY OF ZAGREB

Femur fractures in children can be treated with a number of operative and conservative methods. Numerous factors determine which method is optimal for a specific fracture. The aim of this research was to analyze distribution of femur fractures in children living in the urban communities of Zagreb and Zagreb County by localization, type and frequency of treatment methods used according to age and fracture mechanism. The research included 103 children aged up to 18 years, treated for femur fractures at the Zagreb University Hospital Centre and Zagreb Children’s Hospital. Data were collected from these institutions and a retrospective study covered the 2010-2015 period. The cause of fracture and diagnosis were coded with the help of the International Statistical Classification of Diseases and Related Health Problems. Operative treatment was applied in 55% of cases, which is contrary to previous researches. The highest incidence of femur fractures was recorded in the 0- to 4-year age groups, accounting for 49.1% of all fractures. These fractures mostly occurred due to falls and were more often treated with non-operative methods. All other age groups were mostly treated with operative methods. Coxofemoral immobilization and traction were used as non-operative methods, whereas flexible intramedullary nailing was the most frequently used operative method. The treatment depended on age, complexity of the fracture, fracture type, fragment displacement, and associated injuries. The cause was also an important factor on choosing the treatment method. Non-operative treatment was mostly used for fractures caused by falls (64.71% of cases due to falls) and operative treatment was mostly used for fractures caused by traffic accidents (79.4% of cases due to traffic accidents). It is a wide-known opinion that the best treatment for femur fractures in children is non-operative treatment. However, recent studies have shown that the use of operative methods in femur fracture treatment is growing. Our cohort of children treated during a five-year period (2010-2015) also underwent operative treatment more often than non-operative one. Two non-operative and eight operative methods were used. With such a large number of methods, it is clear that there is no unique method for all fractures. However, it is clear that the trend of using operative treatment is connected to the perennial trend of considerable sociodemographic and socioeconomic changes in urban settings such as Zagreb. Lifestyle changes directly affect the prevalence of femur fractures among children, as well as approach to treatment choice. General opinion is that most of fractures that occur at an early age can be treated with non-operative methods. Our research on femur fractures in children confirmed this rule. The youngest age group that had the highest incidence of fractures (49.1% of all fractures) was treated with non-operative methods in 75% of cases. Operative methods prevailed in other age groups. Similar results have been published by other authors. In conclusion, nearly half of all femur fractures (49.1%) occurred at a young age (0-4 years). Diaphysis fractures were most common. Most of the fractures that occurred during the 2010-2015 period were treated with operative methods, mostly in children aged 5-9 years. Out of eight different operative methods, elastic stable intramedullary osteosynthesis was most frequently used (60%). Coxofemoral immobilization and traction were used as non-operative methods.

Fractures of the femoral shaft in children: national epidemiology and treatment trends in England following activation of major trauma networks

AIMS

The aim of this study was to describe the epidemiology of closed isolated fractures of the femoral shaft in children, and to compare the treatment and length of stay (LOS) between major trauma centres (MTCs) and trauma units (TUs) in England.

PATIENTS AND METHODS

National data were obtained from the Trauma and Audit Research Network for all isolated, closed fractures of the femoral shaft in children from birth to 15 years of age, between 2012 and 2015. Age, gender, the season in which the fracture occurred, non-accidental injury, the mechanism of injury, hospital trauma status, LOS and type of treatment were recorded.

RESULTS

A total of 1852 fractures were identified. The mean annual incidence was 5.82 per 100 000 children (95% confidence interval (CI) 5.20 to 6.44). The age of peak incidence was two years for both boys and girls; this decreased with increasing age. Children aged four to six years treated in MTCs were more likely to be managed with open reduction and internal fixation compared with those treated in TUs (odds ratio 3.20; 95% CI 1.12 to 9.14; p = 0.03). The median LOS was significantly less in MTCs than in TUs for children aged between 18 months and three years treated in both a spica (p = 0.005) and traction (p = 0.0004).

CONCLUSION

This study highlights the current national trends in the management of closed isolated fractures of the femoral shaft in children following activation of major trauma networks in 2012. Future studies focusing on the reasons for the differences which have been identified may help to achieve more consistency in the management of these injuries across the trauma networks.

Spica casting for pediatric femoral fractures: a prospective, randomized controlled study of single-leg versus double-leg spica casts

BACKGROUND

At many centers, double-leg spica casting is the treatment of choice for diaphyseal femoral fractures in children two to six years old. We hypothesized that such patients can be effectively treated with single-leg spica casting and that such treatment would result in easier care and better patient function during treatment.

METHODS

In a prospective, randomized controlled study, fifty-two patients two to six years old with a diaphyseal femoral fracture were randomly assigned to be treated immediately (after consent was obtained) with a single-leg (twenty-four patients) or double-leg (twenty-eight patients) spica cast. Serial radiographs were evaluated for maintenance of fracture reduction with respect to limb length, varus/valgus angulation, and procurvatum/recurvatum angulation. After cast removal, the performance version of the Activities Scale for Kids questionnaire and a custom-written survey were administered to the parents so that they could evaluate the ease of care and function of the children during treatment. Means were compared between treatment groups with use of Student t tests. P values of <0.05 were considered significant.

RESULTS

All limbs healed in satisfactory alignment. The children treated with a single-leg spica cast were more likely to fit into car seats (p < 0.05) and fit more comfortably into chairs (p < 0.05). Caregivers of patients treated with a single-leg cast took less time off work (p < 0.05). There were no major complications.

CONCLUSIONS

Treatment of pediatric femoral fractures with a single-leg spica cast is effective and safe, and postfracture patient care is facilitated.

[Randomised clinical trial on pain control in intertrochanteric fractures of the femur with and without skin traction]

AIM

To evaluate the level of pain control among patients with intertrochanteric fracture of the femur with and without the application of skin traction.

METHODS

A randomised, single centre, parallel, controlled and open, clinical trial performed in a hospital environment. The study subjects were patients with an intertrochanteric femur fracture seen in the Emergency Department. A non-probabilistic and consecutive sample of 40 patients (power 80% CI: 95%), was used. The patients were randomly assigned (1:1) to treatment with or without skin traction. The assignment was made by means of sealed envelopes. The principal variable of study was the evaluation of the pain at 48 hours after admission. Data was collected during February to October 2008 using an ad hoc questionnaire. Data was collected at baseline, 2 h, 24 h and 48 h after admission.

RESULTS

At 48 hours after admission, the mean baseline pain improved by 4.4 points (SD: 1.8) (P<.001), the differential effect of the level of pain between both study groups was 0.7 points of the VAS scale (95% CI, -0.7 to 0.6), while the effect of traction showed no statistically significant differences (P=.721). One patient was withdrawn due skin reaction to the traction adhesive.

CONCLUSIONS

The treatment with skin traction in the patients with intertrochanteric fracture of femur does not produce changes in the progression of the pain in comparison with the patients without skin traction.

Mandibular traction--an alternative treatment in infants with Pierre Robin sequence

PURPOSE

In the Pierre Robin sequence, retrognathia and glossoptosis lead to airway obstruction in infants with or without cleft palate. Mandibular distraction has gained acceptance for the treatment of airway obstruction. However, surgical interventions can result in complications. In our institution, mandibular traction is the standard treatment in cases of severe respiratory distress.

PATIENTS AND METHODS

A retrospective study was performed of all infants treated for Pierre Robin sequence at our institution from 1979 to 2007. The diagnosis and type of treatment (positioning/palatal plate or mandibular traction) were evaluated. The palatal plate had several knobs at the anterior alveolar ridge to direct the tongue forward. Mandibular traction was applied using weights transmitted onto the mandible by a custom-made plate fixed at the mandible with circumferential wiring.

RESULTS

Nineteen children required airway treatment because of repeated cyanotic episodes and respiratory adaptation disorders. Of these 19 children, 8 had been diagnosed with pure Pierre Robin sequence and 11 also had other congenital abnormalities. Of the 19 patients, 10 (56%) were treated nonoperatively by lateral or prone positioning and/or wearing a palatal plate to stimulate the tongue. In 8 patients, conservative management was not sufficient, and continuous mandibular traction was performed for 2 to 5 weeks using weights of 50 to 200 g. One patient required a tracheostomy because of tracheomalacia.

CONCLUSIONS

Surgical therapy using mandibular traction is a minimally invasive alternative to more invasive procedures because no serious complications such as scars or damage to the nerves were encountered.
