Surgical treatment of pediatric femoral shaft fractures

Current practices in the management of closed femoral shaft fractures in children: A nationwide survey among Dutch orthopaedic surgeons

Background

There remains a lack of high-quality evidence on the treatment of pediatric femur shaft fractures. Therefore, treatment choices may still be based on personal preference of treating surgeons. To gain insight in considerations regarding treatment options, we conducted a survey among Dutch trauma and orthopedic surgeons.

Methods

This survey was conducted in 2020, regarding treatment considerations for closed femoral shaft fractures in children in different age and weight groups.

Results

One hundred forty-two surgeons were included in the analysis. 31% of participating surgeons considers surgical fixation in children of 2-4 years old, compared to 83% in children of 4-6 years old. In terms of weight, 30% considers surgery in children of 10-15 kg, compared to 77% considering surgery in children weighing 15-20 kg. While most surgeons find traction and spica cast suitable options for children younger than 4 years, a minority also considers these treatment modalities for children older than 4 (traction: 81% versus 19%, spica cast 63% versus 29% respectively). 33% of surgeons considers ESIN under 4 years of age, compared to 88% in children older than 4.

Conclusion

An age of 4 years and a weight of 15 kg seem to be cut off points regarding preference of non-surgical versus surgical treatment of closed femoral shaft fractures. There is a wide range of ages and sizes for which treatment options are still being considered, sometimes differing from the national guideline. This questions guideline adherence, which may be due to a lack of available high-quality evidence.

Paediatric Femoral Diaphyseal Fractures in a South Wales Tertiary Centre: An Account of Trend in Management and Complications Over 16 Years

Femoral shaft fractures in children have seen a number of interesting developments over the past 20 years. This is a retrospective cohort study looking into epidemiological and outcomes data of femoral shaft fractures in children treated at a tertiary centre in Wales from 2005-2021. Over a period of 16 years, there has been a significant increase in the number of rigid or elastic nailing and submuscular plating, coinciding with a dramatic reduction of external fixation for definitive treatment of diaphyseal femoral fractures. All patients above five years of age underwent operative fixation, with elastic or rigid intramedullary nailing the treatment of choice. Following multiple linear regression with 16 possible explanatory factors, this study found a statistically significant increase in time to union for open fractures, pre-operative translation, and operation time. Furthermore, there was a significant increase in post-operative leg length discrepancy for right versus left-sided fractures. Overall complication rates were 4% for minor and 8% for major complications. Complication rates were lowest for rigid intramedullary nailing and highest for external fixation. No cases of avascular necrosis were found for 27 rigid intramedullary nails inserted. Overall this study reports treatment choices and outcomes in keeping with current trends in management for paediatric femoral shaft fractures.

Leg length discrepancy after skeletal maturity in patients treated with elastic intramedullary nails after femoral shaft fractures in childhood

PURPOSE

The purpose was to study radiographic and perceived leg length discrepancy after skeletal maturity in patients treated for femoral shaft fractures with elastic stable intramedullary nails in childhood.

METHODS

Thirty-five adults underwent standing radiographs and answered a questionnaire regarding perception of leg length discrepancy. Demographic data, fracture characteristics, angulation, stability of fixation, and callus formation, at time of fracture, were assessed.

RESULTS

Mean age at fracture was 10.2 (4.9-16.7) years, and mean follow-up time was 11.1 (3.8-16.8) years. In 8 of 35 participants, the fractured limb was 11-15 mm longer than the non-fractured, and in 16, 1-10 mm longer. In eight participants, the fractured limb was 1-10 mm shorter than the non-fractured, and in three participants, 12-23 mm shorter. The younger the child, the greater the lengthening (R_s = -0.49, p = 0.003). The greater the femoral angulation at time of fracture, the greater the shortening (R_s = 0.42, p = 0.013). There was no significant correlation between stability of fixation or callus formation 1 month postoperatively and radiographic leg length discrepancy after skeletal maturity. Fourteen (40%) had perception of leg length discrepancy at follow-up, of whom eight had a radiographic leg length discrepancy of 10-24 mm.

CONCLUSION

Treatment with elastic stable intramedullary nail of femoral shaft fracture in childhood may result in radiographic leg length discrepancy. Younger children were more prone to lengthening and should possibly be assessed before skeletal maturity. The degree of fracture stability or callus formation at the time of fracture did not significantly affect leg length discrepancy. Perception of leg length discrepancy was not necessarily associated with a radiographic leg length discrepancy (≥10 mm).

Treatment of closed femoral shaft fractures in children aged 2-10 years: a systematic review and meta-analysis

OBJECTIVE

To review current literature on treatment of closed femoral shaft fractures in children of 2-10 years old, with subgroup analysis of children aged 2-6 years, comparing intramedullary nailing (IMN) to conservative treatment modalities.

METHODS

We included clinical trials and observational studies that compared traction and subsequent casting (TSC), spica casting and IMN for treatment of femur shaft fractures in children of 2-10 years of age. Subgroup analysis of children aged 2-6 years was performed.

RESULTS

Compared to treatment with immediate spica casting, IMN led to significantly less coronal angulation (mean difference (MD): 2.03 degrees, confidence interval (CI) 1.15-2.90), less sagittal angulation (MD: 1.59 degrees, CI 0.82-2.35) and lower rates of LLD (Risk difference (RD): 0.07, CI 0.03-0.11). In terms of rehabilitation, IMN leaded to shorter time until walking with aids (MD: 31.53 days, CI 16.02-47.03), shorter time until independent ambulation (MD: 26.59 days, CI 22.07, 31.11) and shorter time until full weight bearing (MD: 27.05 days, CI 6.11, 47,99). Compared to TSC, IMN led to a lower rate of malunion (RD: 0.31, CI 0.05-0.56), shorter hospital stays (MD: 12.48 days, CI 11.57, 13.39), time until walking with aids (MD: 54.55, CI 40.05-69.04) and full weight bearing (MD: 27.05 days [6.11, 47,99]).

CONCLUSION

Although a lack of quality evidence, this systematic review showed a clear tendency to treatment with elastic intramedullary nails of femoral shaft fractures in children of 2-10 years of age.

Regionalization of Isolated Pediatric Femur Fracture Treatment: Recent Trends Observed Using the Kids' Inpatient Database

BACKGROUND

Isolated pediatric femur fractures have historically been treated at local hospitals. Pediatric referral patterns have changed in recent years, diverting patients to high volume centers. The purpose of this investigation was to assess the treatment location of isolated pediatric femur fractures and concomitant trends in length of stay and cost of treatment.

METHODS

A cross-sectional analysis of surgical admissions for femoral shaft fracture was performed using the 2000 to 2012 Kids' Inpatient Database. The primary outcome was hospital location and teaching status. Secondary outcomes included the length of stay and mean hospital charges. Polytrauma patients were excluded. Data were weighted within each study year to produce national estimates.

RESULTS

A total of 35,205 pediatric femoral fracture cases met the inclusion criteria. There was a significant shift in the treatment location over time. In 2000, 60.1% of fractures were treated at urban, teaching hospitals increasing to 81.8% in 2012 (P<0.001). Mean length of stay for all hospitals decreased from 2.59 to 1.91 days (P<0.001). Inflation-adjusted total charges increased during the study from $9499 in 2000 to $25,499 in 2012 per episode of treatment (P<0.001). Total charges per hospitalization were ∼$8000 greater at urban, teaching hospitals in 2012.

CONCLUSIONS

Treatment of isolated pediatric femoral fractures is regionalizing to urban, teaching hospitals. Length of stay has decreased across all institutions. However, the cost of treatment is significantly greater at urban institutions relative to rural hospitals. This trend does not consider patient outcomes but the observed pattern appears to have financial implications.

Developmental Patterns of the Greater Trochanter in Skeletally Immature Patients

BACKGROUND

Trochanteric entry femoral nailing in immature patients is controversial. Although it has become increasingly accepted in pediatric patients aged 8 years and older, complications related to physeal violation have been reported. To date, the appropriate minimum age for safe antegrade nailing in skeletally immature patients remains to be unknown. The purpose of this investigation was to determine the degree of trochanteric bony and cartilage growth with increasing age to provide normative growth values.

METHODS

A total of 408 serial digitized radiographs of the left hip in 45 healthy children (n=26 female individuals, n=19 male individuals) between the ages of 6 and 14 were retrospectively reviewed by 2 independent authors. Radiographs were examined to measure the changing height of the bony greater trochanter with increasing age. Magnetic resonance imaging (MRI) scans of 55 (n=29 male individuals, n=26 female individuals) contemporary children between the ages of 6 and 14 were evaluated to measure bony greater trochanteric and the overlying cartilage cap height.

RESULTS

Intraclass correlation coefficient values for both radiographic and MRI measurements were excellent. Longitudinal radiographs demonstrated that the bony growth was largely complete by age 11 in male and female individuals. MRI measurements demonstrated that bony trochanteric and overlying cartilage cap height was maximal by age 7 in female individuals and age 8 in male individuals, while no significant difference in bony and cartilage height was appreciated with increasing age in male, female individuals or male+female individuals.

CONCLUSIONS

Combined bony and cartilaginous trochanteric growth is largely complete by age 7 in female individuals and age 8 in male individuals, with increases in the height of the trochanter beyond this age likely coming from ossification of the cartilaginous portions. As such, antegrade intramedullary nailing for closed femoral shaft fractures is reasonable in male and female individuals aged 8 years and older.

Changes in the Treatment of Pediatric Femoral Fractures: 15-Year Trends From United States Kids' Inpatient Database (KID) 1997 to 2012

BACKGROUND

The options for treating femoral fractures in children and adolescents have evolved over the last 2 decades to include a variety of nonoperative and operative methods. The purpose of this study was to identify changes in the types of treatment for pediatric femoral fractures in the United States from 1997 to 2012.

METHODS

From discharge estimates for 1997, 2000, 2003, 2006, 2009, and 2012 in the Kids' Inpatient Database, data were extracted using the International Classification of Diseases, 9th revision, and Clinical Modification for pediatric femoral fracture treatments. Patients included were 0 to 17 years old and were categorized into 5 age groups: younger than 1, 1 to 4, 5 to 9, 10 to 14, and 15 to 17 years.

RESULTS

A total of 74,483 estimated discharges were recorded for pediatric patients with femoral fractures in the database for years 1997, 2000, 2003, 2006, 2009, and 2012. A total of 12,986 pediatric femoral fractures were estimated for 1997 and 9813 for 2012, which was statistically different (P<0.0001). Significantly fewer fractures were treated with closed reduction alone in 2012 than in 1997 in age groups 5 to 9, 10 to 14, and 15 to 17 years. Children aged 5 to 9 had more frequent open reduction and internal fixation in 2012 than in 1997, whereas adolescents aged 15 to 17 had less frequent open reduction and internal fixation in 2012 than in 1997.

CONCLUSIONS

Although the number of femoral shaft fractures overall has decreased, the frequency of operative treatment has increased significantly in patients 5 to 9 years of age. Knowledge of these trends can guide educational efforts and resource allocation, but further study is necessary to determine procedure-specific (eg, nailing, plating, external fixation) trends and their clinical and economic impacts.

[Effectiveness of rigid interlocking nails through tip of greater trochanter for fixation of femur shaft fracture in adolescent]

Objective

To explore the effectiveness of rigid interlocking nails through the tip of the greater trochanter for fixation of femur shaft fracture in adolescent.

Methods

A retrospective analysis was made on the clinical data of 23 adolescents with femoral shaft fractures treated between June 2011 and June 2015. Of 23 cases, 19 were male and 4 were female, aged from 13 years and 6 months to 17 years (mean, 15.2 years), weighed from 40 to 77 kg (mean, 53.5 kg). The causes were traffic accident injury in 13 cases, sports injury in 7 cases, and falling injury in 3 cases. Fracture located at the proximal 1/3 in 6 cases, middle 1/3 in 10 cases, and distal 1/3 in 7 cases; fracture was typed as transverse in 10 cases, oblique in 6 cases, spiral in 1 case, and comminuted in 6 cases. The course of disease was 3-17 days (mean, 6.2 days). At last follow-up, the leg length discrepancy, femoral neck shaft angle, femoral neck diameter, and articulotrochanteric distance (ATD) were measured on the X-ray films.

Results

Wounds healed in all patients, and no infection occurred. All patients were followed up 15-36 months (mean, 26.5 months). The patients had no pain and had normal gait, without lameness. The X-ray films showed bone healing at 5-13 months (mean, 6.5 months). No nonunion, delayed union, malunion of more than 5 °, or rotational deformity occurred. The removal time of internal fixations was 12-24 months (mean, 19.5 months) after operation. No heterotopic ossification, re-fracture, proximal femoral deformity, or femoral head necrosis occurred during follow-up. Two patients had early epiphyseal closure of greater trochanter, which had no impact on gait; leg-length inequality of less than 1 cm was observed in 2 cases. At last follow-up, the neck shaft angle, femoral neck diameter, and ATD of normal and affected sides were (131.7±6.3) and (132.9±7.8)°, (34.1±3.2) and (33.9±3.8) mm, and (27.8±9.2) and (26.5±8.5) mm, showing no significant difference between two sides ( t=-0.24, P=0.86; t=0.18, P=0.92; t=1.03, P=0.49).

Conclusion

It is a reliable and effective method to use rigid interlocking nails inserted through the tip of the greater trochanter for the fixation of femur shaft fracture in adolescent.

Clinical outcomes and complications of titanium versus stainless steel elastic nail in management of paediatric femoral fractures-a systematic review

Femoral shaft fractures in children account for approximately 1.6% of all fractures. These fractures can be treated both operatively and non-operatively. Surgical fixation is more common in the age group above 6 years. Elastic intramedullary nails have become the most popular surgical modality of treatment over the last few decades. However, there is continuous debate about which type of elastic nails (titanium and stainless steel) provides better clinical outcomes with less complication. The main purpose of this study was to systematically search for and critically appraise articles comparing clinical outcomes and complications of titanium elastic nail system (TENS) and stainless steel elastic nail system (SSENS) in management of femoral fractures in the paediatric age group. A comprehensive search of MEDLINE, EMBASE, and Cochrane library databases was performed using specific search terms and limits. Applying strict eligibility criteria, the identified studies were screened. Five studies were identified and reviewed. All of the identified studies were non-randomised comparative studies apart from one randomised controlled study. Studies provide contradictory evidence with regard to time to fracture union and time to full weight bearing. Only one study commented on time to nail removal and found that it is shorter in the TENS group. Two studies showed significantly higher rate of malunion in the TENS group, whereas the rest showed no difference. There was no difference in the rates of delayed union or infection between the two groups and no consistent difference in the rates of skin irritation. Three studies compared Flynn's outcome score and found no difference apart from one study which found better scores in the SSENS group. There is no consistent evidence to indicate the advantage of one type of elastic nails over the other in management of paediatric femoral shaft fractures; however, the overall trend is in favour of SSENS especially being cheaper than TENS. Critical appraisal of the studies identified significant methodological deficiencies, and further prospective randomised trials are recommended for more potent evidence.

Changing trends in the management of children's fractures

The management of children's fractures has evolved as a result of better health education, changes in lifestyle, improved implant technology and the changing expectations of society. This review focuses on the changes seen in paediatric fractures, including epidemiology, the increasing problems of obesity, the mechanisms of injury, non-accidental injuries and litigation. We also examine the changes in the management of fractures at three specific sites: the supracondylar humerus, femoral shaft and forearm. There has been an increasing trend towards surgical stabilisation of these fractures. The reasons for this are multifactorial, including societal expectations of a perfect result and reduced hospital stay. Reduced hospital stay is beneficial to the social, educational and psychological needs of the child and beneficial to society as a whole, due to reduced costs.

Is there a role for Ender's nailing of paediatric femoral fractures in a resource-restricted hospital set-up?

Paediatric femur fractures are managed with the titanium elastic nail system (TENS) in the 5-16-year age group. TENS is costly and not easily available in public hospitals. This study compares TENS nailing with stainless-steel Ender's nail fixation of paediatric femur fractures. A retrospective analysis of patient records from 2006 to 2008 yielded 31 children, 5-16 years of age, who underwent flexible nailing for isolated femur fractures. Sixteen children underwent Ender's nailing and 15 underwent TENS nailing. A significant difference in the coronal plane deformity was found in the TENS nailing group compared with Ender's nailing. The union time and time to weight bearing were significantly shorter for Ender's nailing than TENS nailing. The outcome according to Flynn's criteria was significantly better in the Ender's nailing group. The results of Ender's nailing in paediatric femur fractures were comparable with TENS, with a rapid healing time and reduced angular malunion.

Locked intramedullary nailing in the treatment of femoral shaft fractures in children younger than 12 years of age: indications and preliminary report of outcomes

BACKGROUND

Although flexible intramedullary nailing is a popular treatment option for femoral shaft fractures in juvenile and young adolescent patients, it may not be appropriate in some patients because of patient size and/or fracture configuration.

METHODS

Retrospective review over a 3-year period identified 17 skeletally immature patients (18 fractures) with femoral shaft fractures treated with noncannulated rigid locked intramedullary nailing because of a length-unstable fracture or patient overweight or obesity. The 14 males and 3 females had an average age of 10 years at the time of injury (range, 7.6 to 11.9 y). Their average weight was 38.3 kg (range, 22.7 to 52 kg), with an average body mass index of 18.9 (range, 13.9 to 26.9).

RESULTS

All fractures united at an average of 13 weeks, with no osteonecrosis, malalignment, malunion, or hardware failure.

CONCLUSIONS

Preliminary results suggest that noncannulated, rigid, locked intramedullary nails can be used safely and effectively for selective fixation of femoral shaft fractures in skeletally immature patients younger than 12 years of age.

Treatment of femoral shaft fracture with an interlocking humeral nail in older children and adolescents

PURPOSE

Rigid interlocking nailing for femoral shaft fracture is ideal for use in adolescents in terms of stability of the fracture and convenience for the patient. However, numerous authors have reported that rigid interlocking nailing has some limitations in this age group due to the risk of complications. We evaluated the results of intramedullary nailing for femoral shaft fractures with an interlocking humeral nail in older children and adolescents.

MATERIALS AND METHODS

We retrospectively reviewed records of patients treated with an interlocking humeral nail. Radiographs were examined for proximal femoral change and evidence of osteonecrosis. Outcomes were assessed by major or minor complications that occurred after operative treatment.

RESULTS

Twenty-four femoral shaft fractures in 23 patients were enrolled. The mean age at the time of operation was 12 years and 8 months and the mean follow- up period was 21 months. Bony union was achieved in all patients without any complications related to the procedure such as infection, nonunion, malalignment and limb length discrepancy. All fractures were clinically and radiographically united within an average eight weeks. No patients developed avascular necrosis of the femoral head and coxa valga.

CONCLUSION

Intramedullary nailing through the greater trochanter using a rigid interlocking humeral nail is effective and safe for the treatment of femoral shaft fractures in older children and adolescents.

[Pediatric femur fractures, epidemiology and treatment]

BACKGROUND/AIM

Femur fractures in children most often occur as a consequence of traffic accidents, during play and sport activities, and due to different pathological states. Diagnosis is rather simple and it includes physical and radiographical examination. Femur fractures treatment in children can be operative and unoperative, depending on several facts: age, localisation and type of fracture, joint injuries of soft tissues, the presence of other injuries (in polytrauma), economical and social aspects, ect. The aim of this study was to present epidemiological characteristics of pediatric femur fractures, that is in the stage of development, including a special analysis of the used treatment techniques, as well as the comparison of the obtained data with those from the literature.

METHODS

The evaluation included following parameters: age, gender, cause, localisation and type of femur fracture, applied treatment and hospitalisation duration.

RESULTS

Among the presented 143 patients with femur fracture, 109 were boys and 34 were girls (3.2:1 ratio; p = 0.0001). Average age for both genders was 8.6 years, and no difference between boys and girls were found for the age (p = 0.758). In total, the most common fracture was diaphyseal fracture of femur in 93 (65.03%) patients. The second was proximal fracture in 30 (20.98%) patients, and the last distal fracture of the femur in 20 (13.99%) patients (p = 0.0001). Three main causes of femur fracture can be distinguished: during play and sport activities in 67 (46.8%) children, in traffic accidents in 64 (44.8%) children, and pathological fractures in 12 (8.4%) children. Inoperative treatment was applied in 82 (57.3%) patients, and operative one in 61 (42.7%) patients. The most common treatment was traction, in 71 (49.6%) patients, followed by immobilization by hip spica cast mostly in young children. Intramedullar elastic nailing was applied in 16 (11.2%) cases, and intra-medullar rigid nailing (Küntscher) in 19 (13.3%) cases. Significantly longer hospitalization period was detected after traction (21 days) comparing to other ways of treatment, mainly operative or hip spica cast (5 to 10 days).

CONCLUSION

In young children the standard treatment was hip spica cast after traction. Intramedullar elastic nailing is a modern trend accepted as standard in our approach to femur fracture treatment in children.

Antegrade intramedullary nailing of pediatric femoral fractures using an interlocking pediatric femoral nail and a lateral trochanteric entry point

BACKGROUND

The treatment of femoral shaft fractures in older children and adolescents using rigid intramedullary (IM) nail fixation offers the advantages of decreased soft tissue stripping, low incidence of malalignment, leg length discrepancy, early ambulation, and decreased hospital stay. Recent reports have described the development of osteonecrosis of the femoral head in children after IM nailing through the piriformis fossa and the tip of the greater trochanter. Others have noted secondary proximal femoral valgus and femoral neck narrowing after antegrade IM nailing. Using the lateral aspect of the greater \trochanter as the starting point avoids the tenuous blood supply of the proximal femur and did not seem to produce avascular necrosis or proximal femoral deformity in early reports.

METHODS

A retrospective clinical and radiographic review of 78 children and adolescents with 80 femoral shaft fractures who underwent IM nail fixation through the lateral aspect of the greater trochanter, with a mean follow-up of 99 weeks, was performed. Twenty-four fractures were observed until skeletal maturity. Final standing anteroposterior radiographs of both lower extremities were used to assess for evidence of osteonecrosis, limb length discrepancy, fracture alignment, and indices around the hips.

RESULTS

All patients went on to union in good clinical alignment without loss of reduction. No nonunions, delayed unions, or malunions were observed. Two patients developed infections postoperatively (2.5%). No patient had evidence of osteonecrosis of the femoral head. There was no significant difference in neck-shaft angle, articulotrochanteric distance, or femoral diameter when compared with the nonsurgical, normal side in these patients.

CONCLUSIONS

Intramedullary nail fixation through the lateral aspect of the greater trochanter in children and adolescents is effective. It does not produce clinically important femoral neck valgus or narrowing. We did not observe osteonecrosis of the femoral head.

Femural shaft fracture in a newborn infant treated with axial external fixator: a case report

BACKGROUND

The authors present a case of femural shaft fracture inanewborn infant treated with axial external fixator.

METHODS

The patient presented at the time of birth with a lumbar myelomeningocele and right femural shaft fracture. The common methods of treatment cannot be used, so 24 hours after birth before neurosurgery, we applied a Mini Penning Orthofix External Fixator for fracture stabilization.

RESULTS

The external fixator was maintained for 30 days and removed after taking a radiograph that showed fracture healing. At the last follow-up (2 years), the patient did not present axial or torsional defects of right lower limb.

CONCLUSIONS

External fixation is not a traditional method for treatment of femural shaft fractures in patients younger than 6 years, but we think that in some cases, when traditional methods (splinting, cast, Pavlik harness) cannot be used, an external fixator is also a good option in patients younger than 2 years and in newborn infants.

MATERIAIS E MÉTODOS: analisamos todos os prontuários do hospital Geral de Pirajussara no período de dezembro de 2005 a dezembro de 2006. Obtivemos 182 pacientes, sendo 71% do sexo masculino e 29% do feminino; 48% brancos e 52% não brancos. RESULTADOS: houve predominância dos indivíduos do sexo masculino com 71% dos pacientes. O mecanismo de trauma mais freqüente foi a queda (36%). A média de dias de internação foi 4,1 dias, com gasto estimado de R$ 649,50 para cada paciente. A taxa de mortalidade foi de 2,74%, sendo o traumatismo crânio-encefálico responsável por 80% da mortalidade e os maus tratos presentes em 40% dos óbitos. CONCLUSÃO: a população pediátrica tem particularidades que a tornam distinta da população adulta em relação à epidemiologia e manejo das lesões.

Paediatric femoral fractures: factors influencing length of stay and readmission rate

AIM

This report describes factors influencing length of stay and unplanned readmissions within 30 days of discharge for children presenting with femoral fractures to Starship Hospital.

METHODS

The charts and radiographs of all children admitted with femoral shaft fractures between January 1998 and December 2002 were reviewed, excluding pathological fractures. The type of management, the length of stay and the unexpected readmission rate within 30 days were recorded. Ninety-three children with 95 femoral fractures were included in the study.

RESULTS

Forty-six fractures were treated by application of immediate hip spica and 49 by other surgical methods (21 by external fixation, 20 by flexible intramedullary nailing and 8 by other methods). Patients with isolated femur fractures treated by either hip spica application or other operative fixation had median lengths of stay of 3 days (range 1-10 days) and 6 days (range 2-15 days), respectively. Patients with associated injuries, whose femur fractures were treated by either hip spica application or other operative fixation, had longer median lengths of stay of 5 days (3-15 days) and 17 days (5-70 days), respectively. Nine of the 93 children had an unplanned return to the operating theatre during their initial hospital stay, with increased length of stay in 5 as a result. A further 21 children were readmitted within 30 days of discharge with problems of loss of fracture alignment and cast damage in the hip spica group; pin-site infections in the external fixation group and pain around the distal nail insertion site in the flexible intramedullary nailing group. Despite these early problems, fracture alignment was satisfactory at union in 89 of the 95 fractures, with satisfactory remodelling in the remaining six fractures at follow-up.

CONCLUSIONS

The presence of associated injuries was a key factor in the length of the initial hospital stay. However, the need for further operative interventions in the first hospital stay also increased the length of stay in some patients. Overall, the operative management of femoral fractures is resource intensive with a significant need for further minor operative intervention, regardless of the type of initial management.

Femur fracture in preschool children: experience with flexible intramedullary nailing in 72 children

Spica cast immobilization is the preferred treatment for closed femur fracture in preschool children. Flexible intramedullary nailing (FIN) is an alternative treatment but has never been specifically evaluated in this age group. A retrospective analysis of 72 children (mean age, 4.1 years; age range, 1.5-5.9 years) with 73 femur fractures treated by means of FIN was performed. The mean length of stay in hospital was 9.1 days (range, 1-46); weight bearing was started at a mean of 16.4 days (range, 1-60 days) after surgery. Follow-up was available in 62 children (mean, 36.7 months; range, 4-124 months). Complications included early distal nail exteriorization in 9 children (12.3%) during the first 10 years of the study. More than 1 cm of femur overgrowth was noted in 6 children (8.2%). Preschool children with femur fracture treated by means of FIN benefited from short hospital stay, early mobilization and weight bearing. Technique-related complications could be avoided. Long-term follow-up is mandatory in these children.

Epidemiology and mechanisms of femur fractures in children

The most common pediatric orthopaedic injury requiring hospitalization is a femur fracture. This study aimed to identify the epidemiology and mechanisms of injury so that these injuries might be reduced through specifically targeted safety measures. Data for this study were culled from the 2000 Kids' Inpatient Database representing over 2.5 million pediatric hospital discharges. Of the nearly 10,000 femur fractures, 1076 (11%) occurred in children younger than 2 years; 2119 (21%) in children aged 2 to 5 years; 3237 (33%) in children aged 6 to 12 years; and 3528 (35%) in adolescents aged 13 to 18 years. The most (71%) occurred in male patients. Falls and motor vehicle collisions accounted for two thirds of those injuries, with the incidence of falls greater in the younger children and motor vehicle collisions more prevalent in older children. Fifteen percent of femoral fractures in children younger than 2 years were because of child abuse.
