Abstract

A variable angle clamp is provided for use with a spinal implant assembly having a spinal rod R, a Schantz screw 45, and a connector 10’ receiving a spinal rod R. The connector 10’ includes a stem 16’ and a washer 20’ mounted on the stem 16’ with a first clamping surface defining a variable angle feature. The stem terminates in a T-bar 17’ defining a second clamping surface. The variable angle clamp 100 defines a bore 116 configured to receive the Schantz screw 45. An outer surface 106 of the clamp body defines a variable angle feature for interengagement with the first clamping surface, and an opposite outer surface 108 configured for pressure contact with the second clamping surface. The clamp body 100 further defines a notch 120 therethrough in communication with the bore 116. The notch 120 is configured so that a portion of the washer 20’ extends through the notch 120 and into the bore 116 to contact the bone screw 45 therein.
