Bone grafts are widely performed to fill bone cavities and accelerate bone ingrowth. Advances in minimally invasive surgical techniques to treat bone tumors provide the impetus for minimally invasive bone graft procedures. A special funnel with an inner plunger has been manufactured specifically for the delivery of bone graft substitutes.
Secondary bone cysts in two patients with fibrous dysplasia (a 42-year-old male and a 36-year-old female) were treated with the bone graft substitute β-tricalcium phosphateby implantation through a small fenestration in the greater trochanter using a special funnel. Bone consolidation has been observed at about 6 months after the surgery.
Secondary bone cysts in two patients with fibrous dysplasiaare presented as representative cases for this method. The funnel was particularly useful for proximal femoral cystic lesions, as a solitary bone cyst; it facilitated a minimally invasive surgical procedure without the need for curettage. Small fenestrations reduce the likelihood of surgery-related fractures. Long-term follow-up is necessary to confirm the method and is capable of curing secondary bone cysts in patients with fibrous dysplasia.
骨移植广泛用于填充骨腔并促进骨长入。治疗骨肿瘤的微创外科技术的进步为微创骨移植手术提供了动力。一种带有内部柱塞的特殊漏斗已专门制造用于输送骨移植替代物。
两名纤维发育不良患者(一名42岁男性和一名36岁女性)的继发性骨囊肿,通过使用特殊漏斗经大转子处的小开窗植入骨移植替代物β-磷酸三钙进行治疗。术后约6个月观察到骨愈合。
两名纤维发育不良患者的继发性骨囊肿作为该方法的代表性病例呈现。该漏斗对于股骨近端囊性病变(如孤立性骨囊肿)特别有用;它有助于进行无需刮除术的微创手术。小开窗可降低手术相关骨折的可能性。需要长期随访以确认该方法并能够治愈纤维发育不良患者的继发性骨囊肿。
