“…Many authors have achieved better MSTS functional scores in patients with stable and reconstructed pelvic tumors than those without reconstruction. [6,15] In the reconstruction of pelvic defects; iliofemoral and ischiofemoral arthrodesis, massive allografts, custom made pelvic prostheses, saddle-type or modular pelvic prostheses, ice-cream cone prosthesis are performed by various methods; [5,9,[16][17][18][19] however, all of these methods have reported serious early and late complications. While early complications such as infection and dislocation may delay adjuvant therapies in some patients and affect patient prognosis, septic or aseptic loosening and mechanical failure from late complications may result in additional revisions, progressive bone loss, and reduced functional capacity.…”

This study aims to evaluate survival of patients and implants, functions, and morbidity of surgical technique of reconstruction with a fresh-frozen massive pelvic allograft following a pelvic resection.Patients and methods: Between January 2009 and December 2016, a total of 19 patients (12 males, 7 females; mean age: 35.8±14.4 years; range, 10 to 53 years) who underwent reconstruction with fresh-frozen massive allograft after internal hemipelvectomy were retrospectively analyzed. Patients̓ age, sex, resection types, histopathology and grades, surgical margins, operative times, intraoperative blood loss, complications experienced during their treatment (infection, dislocation, implant failure, nonunion, local recurrence and metastasis), neoadjuvant and adjuvant therapies they received, and functional scores were revelaed and analyzed in 10 years period.Results: According to the Enneking and Dunham classification, two (10%) patients had type I resection only, six (32%) had type I-II, one (5%) had a type II resection, one (5%) had type II-III resection, three (16%) had type I-II-III resection, one (5%) had type I-IV resection, and five (26%) had type I-II-IV resection. The resection involved the acetabulum (type II) in all, but three patients. Several complications were seen in 12 patients, although seven patients had no complication. Pelvic resections had a high mortality rate in patients with malignant tumors and reconstruction with massive allograft had a high morbidity rate with susceptibility to many complications. Prolonged surgical time was found to be directly related to blood loss. Deep infection significantly worsened functional results. Conclusion:Despite the high complication rates seen in pelvic resections, massive pelvic allografts represent a valid option for reconstruction after resection of pelvic tumors, but due to the associated morbidity, patients should be carefully selected.
