title: Major complications following total en bloc spondylectomy for giant-cell tumor.
abstract: The authors present the case of a 32-year-old Caucasian female with a giant-cell tumor of the eighth thoracic vertebra, causing unremitting pain, segmental kyphosis and imminent local instability. A total en bloc spondylectomy by a posterior-only approach was performed, complemented with anterior-column reconstruction with a titanium mesh and structural allograft, as well as pedicle screw fixation. Despite the surgery being uneventful, several complications developed over the ensuing weeks: bilateral hemothorax, empyema and sepsis, requiring numerous revision surgeries for postoperative infection. The same pathogen was identified in different samples collected, including a sample from the allograft used. Only the aggressive therapeutic measures adopted allowed improvement in clinical and analytic parameters. The present report alerts to the possible complications following major spine surgery, and raises concerns on the safety of the bone allografts provided, renewing the interest in the development of alternative bone substitutes.
