The strengths of 3 hip spacer constructs—Steinmann pins, a short intramedullary nail (both cement-incorporated), and a Charnley prosthesis—were determined and compared with the strength of a commercially available hip spacer. The hip prosthesis construct was more than twice as strong as the other 2 constructs and was equivalent in strength to the commercial spacer. For spacer applications in which limited weight-bearing is anticipated, the hip prosthesis construct appears more efficacious, but its pros and cons should be compared with those of the commercial product.
