ABSTRACT
RESUMEN Introducción: Existe un aumento de la evidencia de que la estructura geométrica de la anatomía de la cadera juega un importante papel en la etiología de la fractura. Objetivo: Sistematizar los conocimientos más actuales referentes a las características anatómicas de los parámetros radiográficos de la articulación de la cadera, y su relación con la fractura. Métodos: Se realizó una investigación documental, con los artículos científicos publicados en las bases de datos médicas informáticas como PubMed, Ebsco y SciELo en los últimos 5 años. Resultados: La mayoría de las publicaciones analizan el ángulo cervicodiafisario y el eje de la cadera. Otras medidas analizadas son el eje femoral, la longitud y el ancho del cuello femoral, así como medidas acetabulares. No existe un consenso en la medida del largo del cuello femoral o del eje femoral, a pesar de ser un componente importante de la estructura. El conocimiento de las particularidades de la anatomía y de las características biomecánicas de la cadera permite establecer una base para la comprensión de los factores que afectan esta articulación. Conclusiones: Los estudios que se han realizado sobre las características de los componentes estructurales, demuestran que existe una asociación entre sus dimensiones y la ocurrencia de fractura de cadera, en algunos casos independientes de la densidad mineral ósea(AU)
ABSTRACT Introduction: There is increasing evidence that the geometric structure of the hip anatomy plays an important role in the etiology of the fracture. Objective: To systematize the most current knowledge regarding the anatomical characteristics of the radiographic parameters of the hip joint, and their relationship with the fracture. Methods: A documentary research was carried out, with the scientific articles published, in the last 5 years, in medical computer databases such as PubMed, Ebsco and SciELo. Results: Most of the publications analyze the cervicodiaphyseal angle and the axis of the hip. Other measurements analyzed are the femoral axis, the length and width of the femoral neck, as well as acetabular measurements. There is no consensus on the length of the femoral neck or the femoral shaft, despite being an important component of the structure. Knowledge of the particularities of the anatomy and biomechanical characteristics of the hip allows to establish basis for understanding the factors that affect this joint. Conclusions: The studies that have been carried out on the characteristics of the structural components show that there is association between their dimensions and the occurrence of hip fracture, in some cases independent of bone mineral density(AU)

<p><b>OBJECTIVE</b>To analyze the relationship between radiographic parameters and clinical outcomes of patients with distal radius fractures in elderly patients following conservative treatment, and find the important radiographic parameters with distal radius fractures in elderly patients.</p><p><b>METHODS</b>From May 2012 to May 2015, a retrospective analysis was performed of 45 elderly patients with distal radius fractures treated by conservative treatment, which including 17 males and 28 females with an average age of 64.49 years old from 60 to 89 years old. The imaging parameters were measured and the clinical efficacy was evaluated. The imaging parameters on the standard wrist joint X-ray picture were measured including metacarpal angle, the radius height, the ulna variation, the ulnar angle, and so on. The clinical effect of wrist joint was evaluated by Dienst score standard. Multiple factor linear regression was used to analyze the relationship between the image parameters and the clinical efficacy.</p><p><b>RESULTS</b>All patients were followed up for 12 to 24 months with an average of 17.6 months. All fractures of the distal radius were healed. According to the Dienst evaluation, at the final follow-up the result was excellent in 27 cases, good in 10 cases, fair in 6 cases and poor in 2 cases. There was a significant correlation between the height of the radius, the angle of the palmar and the variation of the ulna and the function of the wrist joint in the imaging parameters. When the radius height more than 8.12 mm, the palmar angle more than -1.64 degree and the ulna variant less than 4.05 mm, the result of Dienst function was better.</p><p><b>CONCLUSIONS</b>The imaging parameters such as the radius height, the palmar angle and the ulna variation are related to the recovery of the clinical efficacy of the distal radius fractures in the elderly. The most important parameter is the radius height, which reminds the surgeon to pay special attention to the reduction of the radius fracture in the elderly.</p>
ABSTRACT
Objective To analyze the clinical features and the correlation between radiographic parameters and incidence of calcaneal spur in the patients from Nanfang Hospital,Southern Medical University,China.Methods Three experienced observers independently used the image acquisition and transmission system (PACS) to collect the data of lateral and axial X-ray images of calcaneus or ankle joint in neutral position from the patients with calcaneal spur and normal controls who had undergone radiological examination in Nanfang Hospital,Southern Medical University from July 2014 through December 2015.Ten radiological parameters of the foot (B(o)hler angle,Gissane angle,calcaneal inclination angle,talocalcaneal angle,talus horizontal angle,posterior facet inclination angle,calcaneal length,height of the posterior facet,absolute foot height,and calcaneal width) were measured in both the patients and normal controls.The location,morphology and length of calcaneal spurs were compared between genders,sides and age groups.Results A total of 216 parpatients were included in the study.Female patients were more than male ones,simple plantar spurs more than simple achilles tendon ones,type B spurs more than type A ones,the length of achilles tendon spurs larger than that of plantar ones,female plantar spurs more than males ones,and the length of right foot plantar spurs larger than that of left foot ones.All the differences above were statistically significant (P ＜ 0.05).There were no significant differences in the location,morphology or length of calcaneal spurs between the age group of ≤ 60 years old and the age group of ＞ 60 years old (P ＞ 0.05).The incidence of calcaneal spur were significantly correlated to Gissane angle (P =0.000,OR =0.944,95％ CI 0.917-0.973),posterior facet inclination angle (P=0.017,OR=0.957,95％ CI 0.924-0.992) and height of the posterior facet (P =0.007,OR =0.933,95％ CI O.886-0.981).Conclusions Calcaneal spur favored more females than males.Plantar spurs were more common than Achilles ones.Plantar spurs of Type B were more common than those of Type A.Achilles spurs were longer than plantar ones.More females suffered plantar spur than males.Right foot spurs were longer than left foot ones.Age had no significant influence on the spur characteristics.The incidence of spur might have been related to the Gissane angle,posterior facet inclination angle and height of the posterior facet of the foot.
ABSTRACT
PURPOSE: The purpose of this study is to analyze the measurement differences of simple radiographs according to radiation projection angle using a phantom and to propose methods for objective analysis of simple radiographs. MATERIALS AND METHODS: We took simple radiographs with different projection angles using a C-arm image intensifier and measured five parameters of the foot on the simple radiographic images. Five parameters include lateral tibiocalcaneal angle, lateral talocalcaneal angle, naviculocuboid overlap, lateral talo-first metatarsal angle, and lateral calcaneo-first metatarsal angle. Intraobserver and interobserver reliability were verified, and then intraclass correlations of parameters were analyzed. RESULTS: Radiographic parameters of the foot showed high intraobserver and interobserver reliability. Lateral tibiocalcaneal angle has a strong negative linear relationship with rotation and a moderate negative linear relationship with tilt. Lateral talocalcaneal angle has a moderate positive linear relationship with rotation and a strong positive linear relationship with tilt. Naviculocuboid overlap has a strong positive linear relationship with rotation and a moderate positive linear relationship with tilt. Lateral talo-first metatarsal angle does not have a linear relationship with rotation and a moderate negative linear relationship with tilt. Lateral calcaneo-first metatarsal angle has a moderate positive linear relationship with rotation and tilt. CONCLUSION: More precise evaluation of the foot with a simple radiograph can be performed by understanding the changes of radiographic parameters according to radiation projection angle.

PURPOSE: To evaluate the relationship between radiographic parameters and clinical results after operative treatment of the displaced intra-articular calcaneal fractures. MATERIALS AND METHODS: We analyzed 35 patients of unilateral displaced intraarticular calcaneal fractures who had operative treatment with minimum follow up of 1 year. At the last follow up, we measured the radiographic parameters including Bohler angle, Gissane angle, heel height, calcaneal length, talocalcaneal angle, talar declination angle, subtalar incongruity between normal and affected site. Clinical results were measured by Creighton-Nebraska Health Foundation Assessment Score (CNH). The correlation between the radiographic parameters and the clinical results were analysed by Pearson correlation method. RESULTS: Among the all radiographic parameters we analyzed, only subtalar incongruity shows strong negative linear correlation with clinical results. The average difference of subtalar incongruity between normal and affected site was 0.54 mm (0~2.5) and the correlation coefficients with CNH score was -0.784 (p=0.002). CONCLUSION: We suggest that the subtalar incongruity is significantly correlated with the clinical results after operative treatment of the displaced intraarticular calcaneal fractures.

OBJECTIVE: To determine the relation of Radiographic Scoring System and Scoliosis Research Society-22 (SRS-22), a revised form of health-related quality-of-life (HRQL) questionnaire in idiopathic adolescent scoliosis patients. METHOD: A patient group was made up of 41 adolescents who were diagnosed as idiopathic scoliosis. A control group of 17 persons with Cobb's angle <10degrees was established. To evaluate psychosocial condition, SRS-22 was used to collect the data on both patient and control group. Roentgenographic study was conducted to obtain the Radiographic Deformity Score and evaluate the curve pattern. RESULTS: Pain, self image/appearance, mental health and total score of SRS domains were found to be significantly different between patient and control group (p<0.05). Radiog raphic Deformity Score was positively correlated with pain and self image of SRS domains (p<0.05). However, the pattern of curve was found to be not correlated with SRS score. CONCLUSION: We could evaluate a psychologic condition of idiopathic adolescent scoliosis using Scoliosis Research Society-22 (SRS-22) health-related quality-of-life (HRQL) questionnaire. The more severe spinal deformity, it had the more negative influence on psychologic conditions in idiopathic adolescent scoliosis patients. Therefore, the clinician who is managing idiopathic adolescent scoliosis patients should consider their psychosocial conditions.
