title: A plastic intermedullary plug for total hip arthroplasty.
abstract: Plugging of the medullary canal during total hip replacement creates better cement fixation and thereby prevents subsequent loosening of the femoral component. Methods of plugging involve the use of cement or bone plugs. Both methods have limitations, are time-consuming and can bae ineffective. A high-density polyethylene plug is convenient material for plugging the medullary canal. Laboratory studies show that the plug generates an intramedullary pressure when the proximal femoral canal is being cemented. In 50 patients undergoing total hip replacement, this bullet effectively restricted the cement cone of the proximal femur. The method of insertion was simple, efficient and expedient.
