Assessment of the Risk of Contralateral Non Simultaneous Neck of Femur Fracture in the Elderly.

Not Applicable

• Conditions: Neck of Femur Fracture
• Interventions: Other: CAT scan (CT scan)

• Registration Number: NCT02577081
• Lead Sponsor: Meir Medical Center

Brief Summary

Neck of femur fractures are common in the elderly and are the source of significant morbidity and mortality. This study is based on a new technique developed in Ben Gurion University, with which investigators are able to asses the structural 3 dimensional strength of a bone by applying a unique simulation on a CAT scan of the bone. The purpose of this study is to evaluate the risk of a contralateral neck of femur fracture after the first neck of femur fracture and to estimate the potential fracture characteristics.

Detailed Description

Neck of femur fractures are common in the elderly and are the source of significant morbidity and mortality. literature shows that around 10 percent of those who fracture their femoral neck for the first time will later fracture their contralateral neck of femur and in most cases with the same fracture characteristics. This study is based on a new technique developed in Ben Gurion University, with which investigators are able to asses the structural 3 dimensional strength of a bone by applying a unique simulation on a CAT scan of the bone. The purpose of this study is to evaluate the risk of a contralateral neck of femur fracture after the first neck of femur fracture and to estimate the potential fracture characteristics.

Arm && Interventions

Group	Intervention	Description
CAT scan	CAT scan (CT scan)	A CAT scan will be done for all participants. The scan will include the pelvis and 2 femurs.

Primary Outcome Measures

Name	Time	Method
The risk of a contralateral neck of femur fracture	5 years	A patient specific analysis based on CT scan and finite element analysis will be done on both neck of femurs.

Secondary Outcome Measures

Name	Time	Method
3 dimensional charataristics of the neck of femur fracture	1 year	The CAT scan will provide 3 dimensional characteristics of the current neck of femur fracture as well as the predicted one in the contralateral femur. The fracture will be described using orthopaedic classifications, such as: garden classification for neck of femur fractures and AO classification for intertrochanteric fractures of the femur.
