Variation in the PTH Gene, Hip Fracture, and Femoral Neck Geometry in Elderly Women

Aim: This study aimed to review the clinical findings and surgical intervention of the hip fracture at the Hue University Hospital in Vietnam. Methods:The data of proximal femoral fractures was collected retrospectively. All patients, in a period of 5 years, from Jan 2008 to December 2012, suffered either from intertrochanteric or femoral neck fractures. The numbers of patients were gathered separately for each year, by age groups (under 40, 40-49, 50-59, 60-69, 70-79, older) and by sex. We analyzed what kind of treatment options were used for the hip fracture. Results:Of 224 patients (93 men and 131 women) studied, 71% patients are over 70 years old, 103 women and 56 men (p<0.05). For patients under 40 years, there were 1 woman and 11 men (p<0.05). There were 88 intertrochanteric and 136 femoral neck fractures. There was no significant difference in the two fractures between men and women. The numbers of hip fracture increased by each year, 29/224 cases in 2010, 63/224 cases in 2011, 76/224 cases in 2012. Treatment of 88 intertrochanteric fractures: 49 cases (55.7%) of dynamic hip screw (DHS), 14 cases of hemiarthroplasty (15.9%), 2 cases of total hip replacement (2.3%). Treatment of 136 femoral neck fractures: 48 cases of total replacement (35.3%), 43 cases of hemiarthroplasty (31.6%), 15 cases of screwing (11%). In cases of 40 patients (17.9%) hip fracture was managed conservatively, 23 were femoral neck fractures and 17 were intertrochanteric fractures. Conclusions: Hip fracture is growing challenge in Hue medical university hospital. The conservative approach is still high in people who could not be operable due to severe medical conditions as well as for patients with economic difficulties. Over 70% of the hip fractures in people 70+ are caused by osteoporosis. The number of hip fracture is increasing in the following years, most likely due to the increase in the prevalence of osteoporosis. Early detection and prevention of osteoporosis should be addressed, particularly in high risk population. More aggressive surgical approach should be implemented in order to improve the quality of life in patients with hip fractures. Key words:Hip fracture.

Abstract Background Hip geometry influences hip fracture risk. Hip fractures are common, and they are associated with pain, disability, premature death and marked costs on society. Osteoporotic fractures are frequent in Arctic populations and increase with advancing age in this society with a steep rise in life expectancy. Greenland Inuit is a distinct ethnic group, and data on hip geometry is missing. We thus aimed to describe hip geometry in 7.7 years of consecutive hip fracture patients in Greenland. Methods We evaluated collodiaphysial angle, femoral neck length, the outer and inner diameter of the femur at 2 and 5 centimetres below the centre of the lesser trochanter and the cortical thickness from pelvic and hip radiographs in all patients operated in Greenland over 7.7 years. We included all 84 patients with one non-fractured hip visible for geometric analysis. Analyses were conducted in duplicate. Results We found a collodiaphysial angle of 134.8/132.6o in men/women (p = 0.06) and a femoral neck length of 38.0/33.9 mm in men/women (p = 0.001). Cortical thickness was affected by sex in the adjusted analysis (p < 0.001). Cortical thickness index at 5 cm below the centre of the lesser trochanter decreased with age (p = 0.026) and may be influenced by height (2 cm below the centre of the lesser trochanter, p = 0.053). Conclusion Our findings differed from European data and suggest a delicate balance in hip geometry in Arctic populations. Ethnic peculiarities influence the structure of the hip and may influence fracture risk. A focus on hip geometry and risk factors for osteoporotic fractures in Arctic populations is warranted.

Abstract Summary In Kyoto Prefecture, Japan, the number of hip fractures increased during 2013–2017 compared to 2008–2012. However, the estimated overall incidence rate increased only in femoral neck fractures in men aged ≥75 and women aged ≥85. Purpose The incidence rate of hip fractures in Japan has plateaued or decreased. We investigated the annual hip fracture occurrences in Kyoto Prefecture, Japan, from 2008 to 2017. Methods Patients aged 65 years and above who sustained hip fractures between 2008 and 2017 and were treated at one of the participating 11 hospitals were included. The total number of beds in these institutions was 3701, accounting for 21.5% of the 17,242 acute-care beds in Kyoto Prefecture. The change in incidence rate was estimated utilizing the population according to the national census conducted in 2010 and 2015. Results The total number of hip fractures was 10,060, with 47.5% femoral neck fractures and 52.5% trochanteric fractures. A decrease in number was seen only in trochanteric fractures in the group of 75- to 84-year-old women. The population-adjusted numbers of femoral neck fractures showed a significant increase in all age groups in men, whereas in women, there was an increase in femoral neck fractures in the ≥85 group and trochanteric fractures in the age group 65–74, and a decrease in trochanteric fractures in the age group 75–84. The estimated change in incidence rate showed an increase in femoral neck fractures in men aged ≥75 and women aged ≥85. Conclusion In Kyoto Prefecture, the number of hip fractures increased in the second half of the study period (2013–2017) compared to the first half (2008–2012). However, the incidence rate had not increased, except in femoral neck fractures in men aged ≥75 and women aged ≥85.
