Femoral neck fractures in the young patient require prompt anatomic reduction and stabilization to preserve the vascular supply to the femoral head and minimize future need for arthroplasty. Secondary to unique biomechanical and vascular considerations, these injuries are prone to nonunion.
A 29-year-old male with a chronic femoral neck fracture nonunion who experienced successful fracture healing and symptom resolution following Bone Marrow Aspirate Concentrate (BMAC) administration.
Femoral neck nonunion in young patients is a challenging problem with treatment strategies aimed at improving the biological and biomechanical fracture environment. While the use of both vascularized and nonvascularized bone grafting has shown promising results, they have high complication rates and substantial donor site morbidity. BMAC has demonstrated multiple uses throughout orthopedic surgery and may result in an improved fracture healing environment with minimal patient morbidity.
The success of the BMAC procedure for this patient is promising and may be considered in similar patients, with or without revision internal fixation methods.
年轻患者的股骨颈骨折需要及时进行解剖复位和固定，以维持股骨头的血供，最大限度地减少未来需要进行关节置换的可能性。由于独特的生物力学和血管考虑因素，这些损伤容易发生骨不连。
一名 29 岁男性，患有慢性股骨颈骨折不愈合，在接受骨髓抽吸浓缩物（BMAC）治疗后成功愈合骨折并缓解症状。
年轻患者的股骨颈不愈合是一个具有挑战性的问题，治疗策略旨在改善生物力学和骨折环境。虽然使用血管化和非血管化植骨都显示出了有前途的结果，但它们的并发症发生率高，供区并发症发生率高。BMAC 在骨科手术中有多种用途，可能会改善骨折愈合环境，同时患者的发病率最低。
对于这位患者，BMAC 手术的成功是有希望的，对于类似的患者，无论是否采用翻修内固定方法，都可以考虑采用该方法。
