Iliac particulate cancellous bone and marrow (PCBM) is still the most predictable autogenous graft material for vertical ridge reconstruction because of its high cell content as well as osteoinductive and osteoconductive properties. However, postoperative meralgia paresthetica, gait disturbance, pain, and bleeding have been reported following conventional harvesting from the anterior iliac crest. We present a case of minimally invasive harvesting of iliac PCBM. A short incision was made, and the iliac crest was exposed after elevation of the periosteal membrane. Only the iliac cortical bone was removed using a trephine bur to avoid perforation. PCBM was harvested with hand curettes and grafted into the vertical ridge defect. Because of the small surgical field, gait disturbance was resolved within 1 day without other postoperative complications. This technique is potentially useful for harvesting a small amount of iliac PCBM.
髂骨颗粒松质骨和骨髓（PCBM）因其高细胞含量以及骨诱导和骨传导特性，仍然是用于垂直牙槽嵴重建最可预测的自体移植材料。然而，据报道，传统的从前髂嵴采集术后会出现感觉异常性股痛、步态障碍、疼痛和出血。我们报告一例微创采集髂骨PCBM的病例。做一个短切口，在骨膜掀起后暴露髂嵴。仅使用环钻去除髂骨皮质骨以避免穿孔。用手用刮匙采集PCBM并植入垂直牙槽嵴缺损处。由于手术视野小，步态障碍在1天内得到缓解，且无其他术后并发症。该技术可能有助于采集少量的髂骨PCBM。
