Biomechanical research of the effect of polyvinyl alcohol hydrogel prosthetic disc nucleus on lumbar kinematic behaviour
Objective:To study the effect of prosthetic disc nucleus on the three-dimensional kinematic behaviour and disc height of L4/5.Method:Seven adult human cadaveric lumbar motion segments were loaded with moments of 8.0Nm in flexion-extension,lateral bending,
