BARTOLOMEO, César et al. Aloinjerto fresco congelado en cirugía de columna lumbar: ¿Aumenta la tasa de infección?. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2018, vol.83, n.3, pp.188-191. ISSN 1852-7434.

Introduction: Postoperative infection in lumbar spine is unfortunately common, multifactorial and a potentially devastating complication that is associated with increased morbidity and the need for future surgery, being eventually fatal. To reduce postoperative morbidity, medication and hospital stay, we began to use fresh-frozen bone allograft of femoral head from living donors in short lumbar arthrodesis. The aim of the present study was to analyze the rate of infection in patients with short lumbar arthrodesis with fresh-frozen bone allograft versus bone autograft. Methods: Retrospective study in 153 patients divided into two groups: group A, 84 patients with iliac crest autograft and group B, 69 patients with fresh-frozen bone allograft, from March 2009 to January 2014, undergoing instrumented posterolateral lumbar spinal fusion surgery. Results: Three of the 153 operated patients were lost at follow-up (2 in group A and 1 in group B) leaving the sample with 150 patients (82 in group A and 68 in group B). There were three infections caused by methicillin-sensitive Staphylococcus aureus in group A (4.5%). No patient required transfusion. Conclusions: The use of fresh-frozen bone allograft in posterolateral lumbar spine surgeries for degenerative causes is not associated with an increase in the infection rate. We consider that fresh-frozen bone allograft is an excellent alternative, because it reduces surgical and hospitalization times.
