چکیده

BACKGROUND A number of different bone geometries have been reported to be correlated with osteoporosis, bone mineral density and fractures. Those correlations are used for diagnosis, treatment and prediction of fracture risk in osteoporosis cases. However there have been no studies of significant bone parameters predicting osteoporosis and hip fracture in Thailand OBJECTIVE To evaluate the correlation between geometric parameters of the proximal femur and both the Singh index and bone mineral density as well as to investigate the relationship between those two metrics and osteoporotic hip fracture in the Thai population. MATERIAL AND METHOD Forty-four Thai patients with osteoporotic hip fractures andforty-five healthy Thai people matched for age and gender were included in the present study. Bone mineral density and bone geometry from plain hip radiographs of non-fracture sites in the fracture group and proximal femur radiographs of the same site in the healthy group were measured That data were analyzed to determine levels of correlation. Bone geometries were also analyzed to determine hip fracture predictive capacity. RESULTS Correlation between the Singh index and bone mineral density was significant (p < 0.01), with a moderate degree of agreement. The radiograph measurement of the width ofthefemoral medial neck cortex was the only parameter which was statistically significantly correlated with both osteoporosis and with osteoporotic hip fracture (p = 0.014 and p = 0.035, respectively). Each 1 mm reduction in the width of the femoral medial neck cortex increased the osteoporotic hip fracture risk by a factor of 2.7 (OR = 0.37, 95% CI = 0.15-0.93). CONCLUSION In the Thai population, bone geometry from plain radiographs can help predict the risk of osteoporotic hip fracture. Osteoporosis is correlated with a low Singh index value. The width of the femoral medial neck cortex is a reliable predictor of hip fracture risk.

Type II Intertrochanteric Fractures: Proximal Femoral Nailing (PFN) Versus Dynamic Hip Screw(DHS)

  Background: Intertrochanteric fracture is one of the most common fractures of the hip especially in the elderly with osteoporotic bones, usually due to low-energy trauma like simple falls. Dynamic Hip Screw (DHS) is still considered the gold standard for treating intertrochanteric fractures by many. Not many studies compare the DHS with Proximal femoral nail (PFN), in Type II intertrochanteri...

Proximal Femoral Geometry as Fracture Risk Factor in Female Patients with Osteoporotic Hip Fracture

BACKGROUND Proximal femoral geometry may be a risk factor of osteoporotic hip fractures. However, there existed great differences among studies depending on race, sex and age of subjects. The purpose of the present study is to analyze proximal femoral geometry and bone mineral density (BMD) in the osteoporotic hip fracture patients. Furthermore, we investigated proximal femoral geometric parame...

Effects of Hip Geometry on Fracture Patterns of Proximal Femur

  Background: Some studies have previously shown that geometry of proximal femur can affect the probability of fracture and type of fracture. It happens since the geometry of the proximal femur determines how a force is applied to its different parts. In this study, we have compared proximal femur’s geometric characteristics in femoral neck (FNF), intertrochanteric (ITF) and Subtrochanteric (ST...

Development of an Animal Fracture Model for Evaluation of Cement Augmentation Femoroplasty: An In Vitro Biomechanical Study

Osteoporotic hip fracture is the most severe kind of fracture with high morbidity and mortality. Patients' ambulation and quality of life are significantly affected by the fracture because only 50% regain their prefracture functional status, even if they undergo surgeries. There are many issues associated with the current preventive methods e.g., cost, side effects, patient compliance, and time...

Challenges of Plate Fixation for Vancouver Type-C Fractures after a Well-Fixed Hip Arthroplasty Femoral Stem

The fixation of distal femoral fractures (Vancouver type-C fractures) following a well-fixed hip arthroplasty femoral stem has become a challenging issue for orthopedic surgeons due to the inter-prosthetic biomechanical effects such as negative, positive, and torsional strain. Surgeons have applied a range of constructs to overcome these difficulties. To minimize the risk of inter-prosthetic fr...
