Comparison of titanium elastic nails with traction and spica cast in treatment of children's femoral shaft fractures

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.

Compared outcomes of femoral shaft fracture treatment in school-age children in Sub-Saharan Africa: Primary open reduction and intramedullary K-wire fixation versus traction followed by spica cast

BACKGROUND

Elastic stable intramedullary nailing has become the treatment of choice for femur shaft fractures in school-age children in developed world. However, in the sub-Saharan Africa, this management is still challenging because of the lack of fluoroscopy in more hospitals. We performed either primary open reduction and intramedullary K-wire fixation (PORIKF) or conservative treatment. The aim of this study was to compare the clinical and functional outcomes of these two procedures employed.

PATIENTS AND METHODS

This retrospective study included 62 children with 64 fractures (10 years on an average; range: 6-15 years) treating for femoral shaft fractures either by PORIKF (n = 21; 23 fractures) or skin traction followed by spica cast (n = 41) between 2008 and 2017. Outcomes were assessed using Flynn criteria. Comparisons were made by Fisher and Student's t-test with a significant P < 5%.

RESULTS

Outcomes were satisfactory in 21 cases (91%) in the PORIKF group compared with 32 (78%) in the conservative group (P = 0.3012). The average hospital stay was 18.6 days in the PORIKF group, whereas it was 20 in the conservative group (P = 0.0601). The mean time for bone union was 13.9 weeks in the PORIKF group and 13.2 weeks in the conservative group, (P = 0.4346). There was a statistically significant difference between the two groups in terms of major complications (P = 0.0177). One patient had osteomyelitis in the PORIKF group. Unacceptable shortening >2 cm was observed only in the conservative group. The average time to return to daily activities was 30 days shorter in the PORIKF group when compared to conservative group (P < 0.05).

CONCLUSION

PORIKF provides better results than conservative treatment. Open reduction did not increase the rate of infectious complication.

Four interventions for pediatric femoral shaft fractures: Network meta-analysis of randomized trials

BACKGROUND

Fractures of the pediatric femoral shaft are uncommon, although serious injuries could lead to long-term disability, pain and an impaired quality of life. There are 4 main interventions: cast (C), plate fixation (PF), titanium elastic nail (TEN) and external fixation (EF). However, for pediatric patients under the age of 16, which intervention is the best choice remains a controversial topic. Therefore, a comprehensive network meta-analysis (NMA) is needed to summarize existing studies and to compare the safety and efficacy of the interventions for pediatric femoral shaft fractures.

METHODS

We searched through eight electronic databases (PubMed, Embase, Cochrane, Web of Science, CBM, CNKI, Wangfang, and VIP) for randomized controlled trials of femoral shaft fracture in pediatric patients, which were published until the end of March 2020. We performed a Bayesian NMA to integrate the adverse events and fracture union time of all interventions.

RESULT

Twenty-three randomized controlled trials with a total number of 1627 patients were included in our NMA. Among these patients, 386 patients underwent C, 524 patients underwent PF, 574 patients underwent TEN, and 143 patients underwent EF. In terms of adverse events, C had the lowest infection rates and TEN the second lowest infection rates. TEN also had the lowest anchylosis and malunion rates. In addition, TEN had a lower fracture union time than C, PF and EF. Notably, C showed the weakest effects on reducing malunion rates in pediatric patients.

CONCLUSION

This current study indicated that TEN has potential superior clinical outcomes in pediatric femoral shaft fractures compared to C, PF and PF. However, high-quality large sample RCTs are still needed.

Maternal-neonatal outcome in pregnancies with non-obstetric laparotomy during pregnancy

In this study maternal and neonatal outcome evaluated in each trimester of pregnancies with non obstetric laparotomies. In this descriptive-analytic study, 100 pregnant women operated during pregnancy were evaluated. Based on available data a questionnaire comprising general information, kind of surgery as well as the maternal-neonatal outcome was fulfilled. These outcomes were compared in the different gestational ages. In this study, 28 (28%), 48 (48%) and 24 (24%) patients had been operated in the first, second and third trimester, respectively. The patients of these three groups were matched for general characters. Sixty one patients had appendectomy, 30 adnexal mass or torsion, 6% cholecystectomy, 3% abdominal mass. Maternal complications were recorded in 6, 3 and 9% patient in 3rd, 2nd and 1st trimester of pregnancy, respectively. Abortion in first trimester was 8.2%. Low apgar in fifth minute and asphyxia were higher in third trimester. Appendectomy was the most common surgery in the pregnancy. Maternal and fetal complications were higher in third and first trimester. Besides obstetric and pediatric consultation before surgery are necessary for optimal safety of the woman and the fetus.

Effect of left atrium volume on patients' prognosis following acute myocardial infarction

Evaluating left atrium volume is a good way to estimate prognosis in acute myocardial infarction patients because it indicates to time and severity of diastolic dysfunction and longer-term results of acute myocardial infarction. The present study aims at evaluating the effect of left atrium volume on patients' prognosis following acute myocardial infarction. This is a cohort study conducted on 100 patients who were admitted with acute myocardial infarction. They were studied for 9 months and their one-month mortality rate was evaluated. The patients were studied considering demographic factors, risk factors, mechanical and arrhythmic complications and echocardiography indexes such as systolic and diastolic functions and left atrium volume. It was seen that mortality (27.3%, 6.22) in patients with atrium index > 32 mL m(-2) is more than cases with lower atrium index (1.3%, 1.78) (p = 0.001). There was not any meaningful difference in mortality rate of the patients considering age and gender (p > 0.05). This study indicated to lack of any meaningful difference in patients' mortality rate in terms of hypertension, diabetes, smoking and dyslipidemia. But, mortality rate was significantly higher in MI as a result of elevated-ST, diastolic dysfunction, restrictive pattern, ejection fraction of left atrium < 40%, left atrium volume index > 32 mL m(-2). High volume left atrium independently refers to bad prognosis in patients with acute myocardial infarction which is confirmed with outcome clinical predictors and common echocardiography indexes even following modification.

Thyroid cancer, clinical and hystopathological study on patients under 25 years in Tabriz, Iran (2000-2012)

Thyroid cancer comprises a broad spectrum of diseases with variable prognoses. The aim of this study was to assess thyroid cancer in young population using the surveillance, epidemiology and end results database and whether radioactive fallout from the Chernobyl accident in 1986 influenced thyroid cancer incidence among children and adolescents in Tabriz, Iran. Patients aged 5-25 in Tabriz from April 2000 to April 2012 were studied. Using the surveillance and end results database, the study examined the overall incidence of thyroid cancer with variations based on tumor pathology, size and stage, as well as the current surgical therapy of thyroid carcinoma. This study demonstrated a positive correlation between thyroid carcinoma tumor size and stage of disease. Mortality rates were higher among men than women. Recurrence rates are also higher in men. Compared with women, men have greater likelihood ofloco regional lymph node involvement and more than twice the rate of distant metastases. Operative treatment for thyroid cancer also has shifted with Radical dissection+Total thyroidectomy replacing partial thyroidectomy as the most common surgical procedure. Our data indicate that the increasing incidence of thyroid cancer cannot be accounted for fully by an increased detection of small neoplasms. This study show the increasing in thyroid cancer incidence related to exposure to radiation from the Chernobyl accident.
