200 are not constrained to forming a bone plate with a single angle for example in the bone plate 160 shown in fig9 the longitudinal axis 162 of the plate 100 is set at an angle u03b2 with respect to the longitudinal axis 220 of the plate 200 that is larger than the angle u03b1 the range of angles which can be formed in this embodiment is limited in one direction by the rotation stop 222 which impinges on the side wall 140 and in the other direction by the rotation stop 224 which impinges on the side wall 138 fig1 shows a bone plate 170 that includes bone plate modules 100 and 200 and a male end cap 178 the bone plate 170 may be fastened to a bone using bone screws 172 and 174 the bone screw 172 is inserted through the taper 120 the head 176 of the bone screw 172 may be threaded to engage the threaded portion 132 of the taper 120 the threaded portion 132 may be triple lead threaded to provide for use of both locking and non locking screws a compression screw may be used either with or without a threaded portion 132 the screw 174 extends through the bore 226 the bore 226 however has no threads to engage the screw 174 the male end cap 178 however is threaded as shown in fig1 specifically the male end cap 178 includes a male coupling portion 180 with a threaded portion 182 that extends upwardly from a.
