Core Tip

Core tip: The results of this biomechanical study demonstrated that application of precontoured anatomic acetabular buttress plates in posterior wall fractures of the acetabulum provide more stable fixation than 5-hole conventional curved reconstruction plates. For the precontoured anatomic acetabular buttress plate, its features of anatomic contour, low profile, avoidance of joint penetration by locking screws, and allowance of placement of more screws through both the proximal and distal parts of a fracture pattern as needed represent marked advantages over the traditional plate.
