Typical sources for graft material utilized in minimally invasive transforaminal lumbar interbody fusion include both autograft and allograft. Autograft is frequently utilized due to its theorized benefits in promoting fusion. During minimally invasive transforaminal lumbar interbody fusion, autograft is often obtained locally during the laminectomy and facetectomy. However, this locally obtained bone graft has exhibited questionable osteoconductive properties, often necessitating the addition of biologics to improve fusion rates. Iliac crest bone graft (ICBG) has previously been reported to be a safe and efficacious source for bone graft. Although ICBG has been noted to be an excellent material for facilitating fusion, concern for harvest site morbidity has substantially decreased its popularity. The purpose of this surgical technique is to provide a method of minimally invasive ICBG harvesting to potentially reduce the need for extra incisions, shorten operative times, and prevent postoperative graft site morbidity.
微创经椎间孔腰椎椎间融合术中使用的移植材料的典型来源包括自体骨移植和异体骨移植。自体骨移植因其在促进融合方面的理论优势而经常被使用。在微创经椎间孔腰椎椎间融合术中，自体骨移植通常在椎板切除术和小关节突切除术中在局部获取。然而，这种局部获取的骨移植材料的骨传导性能存在疑问，常常需要添加生物制剂以提高融合率。髂嵴骨移植（ICBG）此前已被报道是一种安全有效的骨移植来源。尽管ICBG已被认为是促进融合的优质材料，但对取骨部位并发症的担忧已大大降低了其受欢迎程度。本手术技术的目的是提供一种微创获取ICBG的方法，以潜在地减少额外切口的需要，缩短手术时间，并预防术后移植部位并发症。
