Treatment of scaphoid non-unions is still challenging for responsible hand surgeons, especially in cases of avascular proximal pole non-unions or failed prior surgeries. Several surgical procedures treating scaphoid non-unions have been established. These aim to restore correct anatomy to provide stability and adequate blood flow. Treatment options range from avascular to free, vascularized bone grafts. The two most used free vascularized bone grafts derive from the iliac crest and the medial femoral condyle. The vascular anatomy of the medial femoral condyle graft is more constant, the donor site morbidity lower and the healing rate higher in comparison to the iliac crest graft. It is easier to harvest the femoral condyle graft and additionally, it can be harvested as a cortico-cancellous or osteochondral graft. Looking at all advantage, we come to the conclusion that the free vascularized medial femoral condyle graft is our method of choice for the treatment of a avascular proximal pole non-union of the scaphoid.
对于负责的手外科医生来说,舟骨不愈合的治疗仍然具有挑战性,尤其是在缺血性近端极不愈合或先前手术失败的情况下。已经建立了几种治疗舟骨不愈合的手术方法。这些方法旨在恢复正确的解剖结构,以提供稳定性和充足的血流。治疗选择从非血管化到游离带血管蒂骨移植不等。两种最常用的游离带血管蒂骨移植取材于髂嵴和股骨内侧髁。与髂嵴移植相比,股骨内侧髁移植的血管解剖结构更恒定,供区并发症更少,愈合率更高。采集股骨髁移植更容易,此外,它可以作为皮质松质骨或骨软骨移植进行采集。综合所有优势,我们得出结论,游离带血管蒂股骨内侧髁移植是我们治疗舟骨缺血性近端极不愈合的首选方法。
