Comparison of Proximal Femoral Geometry and Risk Factors between Femoral Neck Fractures and Femoral Intertrochanteric Fractures in an Elderly Chinese Population / 中华医学杂志(英文版)

<p><b>Background</b>Few studies have investigated the differences in proximal femoral geometry and risk factors between patients with different types of hip fracture, especially in elderly Chinese. This study aimed to assess the differences in proximal femoral geometry parameters between patients with femoral neck fractures and patients with intertrochanteric fractures to provide guidance for individualized customized prosthesis and accurate reconstruction of proximal femurs in elderly Chinese patients.</p><p><b>Methods</b>We retrospectively studied the electronic medical records of 198 elderly patients over 65 years of age who were admitted to the orthopedic department with hip fractures between January 2017 and December 2017 in The Third Hospital, Hebei Medical University. Age, fracture site, gender, and proximal femoral geometry parameters (neck shaft angle [NSA], center edge angle [CEA], femoral head diameter [FHD], femoral neck diameter [FND], femoral neck axial length [FNAL], hip axial length [HAL], and femoral shaft diameter [FSD]) were recorded. Student's t-test was used to compare the continuous variables, Chi-square test was used to analyze categorical variables, and multiple logistic stepwise regression analysis was used to evaluate the influencing factors of hip fracture type.</p><p><b>Results</b>Statistically significant differences in NSA (137.63 ± 4.56° vs. 132.07 ± 4.17°, t = 1.598, P < 0.001), CEA (37.62 ± 6.77° vs. 43.11 ± 7.09°, t = 5.597, P < 0.001), FND (35.21 ± 3.25 mm vs. 34.09 ± 3.82 mm, t = 2.233, P = 0.027), and FNAL (99.30 ± 7.91 mm vs. 103.58 ± 8.39 mm, t = 3.715, P < 0.001) were found between the femoral neck fracture group and femoral intertrochanteric fracture group. FHD, FND, FSD, HAL, and FNAL were different between sexes (all P < 0.001). The greater NSA was the risk factor for femoral neck fractures (odds ratio [OR]: 0.70, P < 0.001), greater CEA and longer FNAL were risk factors for femoral intertrochanteric fractures (OR: 1.15, 1.17, all P < 0.001), and greater FND was a protective factor for femoral intertrochanteric fractures (OR: 0.74, P < 0.001).</p><p><b>Conclusions</b>We demonstrate differences in geometric morphological parameters of the proximal femur in different hip fracture types, as well as an effect of sex. These differences should be considered in the selection of prostheses for fracture internal fixation and hip replacements. These data could help guide the design of individualized customized prostheses and improve the accurate reconstruction of the proximal femur for elderly Chinese hip fracture patients.</p>

Internação hospitalar por fraturas de fêmur e outros ossos dos membros em residentes de Pernambuco / Hospitalization for fractures of the femur and other limb bones in residents of Pernambuco

Introdução: Os traumas, além de provocarem impactos significantes sobre as taxas de morbimortalidade, também apresentam repercussões econômicas consideráveis na sociedade, resultando em gastos com os serviços de saúde. Objetivou-se caracterizar os pacientes internados com fraturas do fêmur e de outros ossos dos membros em hospitais de Pernambuco, bem como descrever os gastos decorrentes destas internações. Métodos: Realizou-se um estudo de base populacional, utilizando-se o Sistema de Informações Hospitalares-SIH/SUS cujos dados foram oriundos das Autorizações de Internações Hospitalares (AIHs), do período de 1998 a 2008. Resultados: Das 123.979 internações hospitalares registradas, observou-se uma razão de sexo de 2 homens: 1 mulher, apesar de se verificar, no decorrer do período estudado, altas taxas de incidência nos dois sexos. Em números absolutos, pessoas de 20 a 39 anos sofreram mais fraturas (n=36.455), porém, as maiores taxas de incidência ocorreram em idosos. A média de permanência hospitalar foi de 6 dias e os gastos com internações foram de R$ 76.994.659,12. Mais de 500 óbitos ocorreram, sendo as taxas de mortalidade mais elevadas em mulheres. As Regionais de Saúde de Serra Talhada, Recife, Arcoverde, Petrolina e Afogados da Ingazeira apresentaram taxas de incidência acima de 100 casos por 100mil/ habitantes. Conclusões: Constatou-se um predomínio das fraturas de fêmur e outros ossos dos membros em mulheres e em idosos e, um aumento nos gastos com internações hospitalares (AU)

Introduction: Besides having significant impacts on morbidity and mortality rates, traumas also have considerable economic repercussions for society, resulting in expenditures on health services. This study aimed to characterize the patients hospitalized with fractures of the femur and other limb bones in the hospitals of Pernambuco, as well as describing the expenses arising from these admissions. Methods: We conducted a population-based study using the Hospital System Information (SIH/SUS), whose data were derived from the Hospital Admission Authorizations (AIH) in the 1998-2008 period. Results: Of the 123,979 hospital admissions recorded, a 2:1 male/female ratio was observed despite the high incidence rates in both sexes seen throughout the study period. In absolute numbers, people from 20 to 39 years of age suffered more fractures (n = 36,455), but the highest incidence rates occurred in the elderly. The mean hospital stay was 6 days and the expenditures for hospitalizations amounted to R$76,994,659.12. There were more than 500 deaths, with death rates higher in women. The Regional Health Units of Sierra Talhada, Recife, Arcoverde, Petrolina and Afogados da Ingazeira had incidence rates above 100 cases per 100,000 people. Conclusions: We found a predominance of fractures of the femur and other limb bones in women and the elderly, and an increase in spending on hospital admissions (AU)

Supracondylar Fractures of the Femur / 대한정형외과학회잡지

Supracondylar Fractures of the femur are not as cammon as femoral neck or intertrochanteric fractures, but their treatment may be just as difficult. Few surgeons have had extensive experience with this complex fractures of uncommon frequency. Until a few years ago, conservative treatment was considered superior to internal fixation of supracondylar fractures of the femur in adults. However, the development of new fixation devices and techniques has, according to several investigations, improved the results of the treatment of these fractures. The following clinical results were shown by analysis of 27 cases of femoral supracondylar fractures experienced in the Department of Orthopedic Surgery, Capital Armed Forces General Hospital in the past 3 years from Jan. 1977 to Oec. 1979. 1. The most common cause of these fractures were traffic accidents. 2. Of 27 cases, 11 cases were treated by conservative method, 16 cases were treated by open reduction and internal fixation. 3. Anatomical reduction and rigid internal fixation led to 80% of good to excellent results whereas only 33.4% of good to excellent results were obtained in patients in whom the fixation was not absolutely rigid. 4. In the treatment of supracondylar fractures of the femur, anatomical reduction and rigid internal fixation (80% of good to excellent results) resulted in better functional recovery after union of fractures than conservative treatment (45.5%).
