Air gap magnification is useful in the diagnosis of upper extremity fractures specifically as it applies to nondisplaced fractures of the radial head, carpals and metacarpals. These injuries often prove difficult if not impossible to detect on routine roentgenographs. Gap magnification is technically simple to perform, requires no special equipment, and has been useful in evaluating subtle roentgenographic changes.
Ninety total hip Charnley arthroplasties were performed in 80 patients with failed endoprostheses between July, 1970, and November, 1975. Pain was completely alleviated or minimal in 97.7% of cases. The ability to ambulate improved in all cases with 93.2% good or excellent results. Low grade infection must be considered in treating failed endoprostheses. Appropriate surgical debridement and antibiotic therapy offer a reasonably good chance for success.
