Allograft cortical strut for reconstruction of space-occupying bone lesions.

Abstract

Space-occupying bone lesions present orthopedic surgeons with clinical and operative challenges. Multiple reconstructive procedures have proven successful for small bone lesions but lack the structural support necessary for reconstruction of larger lesions. This study reports the clinical outcomes of patients undergoing excision and reconstruction of large bone lesions with allograft cortical struts without additional internal fixation. This retrospective outcomes study reviewed patients who underwent surgical curettage and cortical strut allograft reconstruction of any space-occupying bone lesion. Clinical, surgical, and imaging data were collected. The primary outcome measures were lesion healing, graft incorporation, long-term pain, return to activity, and presence of complications/recurrences. Seventeen patients met the inclusion criteria. At least partial lesion healing and allograft incorporation was identified in 15 of 17 lesions. Of the 15 patients who did not sustain a recurrence, only 1 did not return to full activities. Mean lesion volume was 107 cc. Average follow-up was 19.6 months. Two recurrences were identified, and no other major complications were identified.
