简要总结
Certain types of fractures require surgical intervention that may involve the use of bone grafts or bone graft substitutes. Many of the materials used as bone graft substitutes suffer from disadvantages such as soft tissue invasion of the fracture area, inadequate blood supply, failure to encourage the production of bone and ectopic bone formation.
A guided bone regeneration (GBR) environment may help in solving these clinical concerns. GBR has been widely used in the field of dentistry since the 1980s to provide stable placement for dental implants
The purpose of this study is to evaluate the safety, performance and initial efficacy of Regenecure's, AMCA Bone Membrane, as a bone stimulating aid for orthopedic trauma applications.

结局指标
主要结局
To demonstrate the safety of the AMCA Bone membrane when used in the treatment of subtrochanteric femoral fractures.
时间窗: 12 months
Safety element will be measured by evaluation of swelling, clinical signs of superficial or deep infection, pain in the operated area. Radiographic healing assessment score.
次要结局
- To evaluate the performance of the AMCA Bone membrane in providing enhanced healing of compromised fractures at risk of non-union.(12 months)
