1. one kind is applicable to the hone lamella (10) of the spatial relationship of fixation in situ at least two osteocommas (80), and hone lamella (10) comprising:

  • Elongated board (11), elongated board (11) has multiple screw aperture (24), each screw aperture has radius (r), nail (28) can be inserted into be anchored on osteocomma (80) by elongated board (11) in osteocomma (80) below by screw aperture (24), and described nail has a radius;

    WithAt least two screw aperture in described multiple screw aperture (24) are adjoined by relief district (60) and form complex-aperture (40), described relief district (60) is arranged on the parallel radius between adjacent screw aperture (24), described complex-aperture (40) has single opening, described single opening has calabash shaped or dumbbell shaped constructs and formed by the isolated screw aperture of a pair next-door neighbour (24) adjacent by described relief district (60), form two adjacent screw aperture (24) of described complex-aperture (40) along by the axis at the center of described two adjacent screw aperture (24), there is centre-to-centre spacing (d), described centre-to-centre spacing (d) at least equals the head radius sum of two nails for described two adjacent screw aperture (24), and described relief district (60) is conducive to being inserted into by nail (28) in osteocomma (80) below with grappling elongated board (11), described at least two screw aperture (24) wherein forming complex-aperture (40) are type thread bone nail window, wherein said complex-aperture (40) has at least two threaded surface portion (35) and at least two without threaded surface portion (36), described at least two is relief district (60) without in threaded surface portion.
