ABSTRACT
BACKGROUND:
Properties of cancellous bone is significant for metabolic diseases, fracture and joint retrograde diseases.OBJECTIVE:
To study the biomechanical properties of cancellous bone.DESIGN:
Experimental observation based on femur specimens as the single sample.SETTING:
Laboratory of Orthopaedic Biomechanics Ninth Affiliated Hospital Shanghai Second Medical University.PARTICIPANTS:
The study was completed in the Laboratory of Orthopaedic Biomechanics, Shanghai Ninth People's Hospital from May to July in 2001,totally 19 male cadaveric femoral heads were selected.METHODS:
Totally 19 cadeveric cancellouce bone specimens(about 30years old) from the bearing area of fresh femur head were tested by compression test.MAIN OUTCOMEMEASURES:
Yield load limiting stress, limiting strain, energy value and elastic modulus of specimens.RESULTS:
The compressive data of cancellous bone were measured, the average value of yield load was (410.64 ± 190.29) N , limiting stress was (8.69 ± 3.75) MPa, limiting strain was (10. 84 ±6.58)%, energy value was (2.54 ± 1.89)J, modulus of elasticity was (40.77 ± 32. 12)MPa, At the early time of loading, the cancellous bone showed elastic deformation, thenCONCLUSION:
The trial indicates that biomechanical properties lighten the pressure of external compression.
