Broken intramedullary nails

Between 1962 and 1987, we treated fifty-six patients for sixty broken
intramedullary nails, using a custom-made hook to extract the distal
fragment of the nail. The charts and radiographs of all of the patients
were reviewed. Thirty-nine of the nails had been inserted in a fresh
fracture, which usually was comminuted; eight had been used for fixation of
an osteotomy; nine, for fixation of a non-union; and four, for treatment of
a pathological fracture. Several small-diameter intramedullary nails broke
at the site of the fracture or non-union. In contrast, the sites of
breakage in the interlocking nails were the interlocking holes and the
welded junction of the top insertional portion and the proximal slot. Many
of the breakages were in patients who had an unstable fracture pattern. The
interval between insertion and breakage ranged from one to 120 months.
