A method for separating and stabilizing adjacent vertebrae (

50

and

52

), comprising: introducing insert (

20

) between vertebrae (

50

and

52

); rotating insert (

20

) to engage cam surfaces (

32

and

34

) thereon against vertebrae (

50

and

52

) to move vertebrae (

50

and

52

) apart; and anchoring insert (

20

) between vertebrae (

50

and

52

).

A posterolateral and percutaneous method of separating and stabilizing adjacent vertebrae (

50

and

52

), comprising: percutaneously introducing a first insert (

19

a

) and a second insert (

19

b

) between adjacent vertebrae (

50

and

52

) with rotational axes (

26

a

and

26

b

) of insert (

19

a

) and

19

b

) being at a generally right angle to one another.

An intervertebral insert (

20

) comprising a body having a posterior end (

22

), an anterior end (

24

), a rotational axis (

26

) between ends (

22

and

24

), and a pair of outwardly facing convexly curved surfaces (

32

and

34

) which are disposed generally parallel to rotational axis (

26

) and which are adapted to engage and separate opposed vertebral surfaces (

50

and

52

) when insert (

20

) is placed between adjacent vertebrae (

50

and

52

) and rotated.
