“…Tantalum has the advantage that it avoids donor-site morbidity of harvesting the iliac crest graft and the possibility of disease transmission. Harvesting autograft at the iliac crest has a reported donorsite morbidity rate of 15% to 48% (postoperative hematoma, infection, hypesthesia, increased postoperative pain, wound dehiscence, cosmetic defect, prolonged pain in the long term, and impairment in ambulation, work, and activities of daily living [17,21,24,38,42]). The cost of tantalum (approximately $1000 per block in the US) is comparable to allograft ($850, plus approximately [3,4,56] Similar to gold standard [19,54] Difficult radiographic assessment of fusion [28,51,54] No donor-site morbidity, no reported complications [19,20,36,37,54] Unlimited Approximately $1000 per piece 5 minutes of preparation time in the operating theater) or harvesting iliac crest autograft (estimated at $600 to $700, as it involves approximately 20 minutes of operating time, suture material, sponges, and dressing) ( Table 1).…”
