An arthroplasty plate and method of use to repair a fractured end of a bone are described. The arthroplasty plate comprises a fixation plate arranged to be secured to a surface of a bone and a connector assembly comprising a barrel extending from the fixation plate and having a bore which opens through the fixation plate. A connector rod is arranged to slide within the bore of the barrel. An articulation component comprises a bearing surface coupled to or arranged to couple to an end of the connector rod which extends from the barrel away from the fixation plate. The connector assembly incorporates an adjustment mechanism arranged to cause the connector rod to slide into or out of the barrel and a locking mechanism arranged to lock the position of the connector rod within the barrel to rigidly space the articulation component apart from the fixation plate.
