简要总结
The investigators will compare intramedullary nailing of open and closed tibia shaft fractures with carbon fiber implant versus titanium implant in a Level I trauma setting.
详细描述
The tibia (long bone in the leg) bears most of the body weight and is the most commonly fractured long bone in the body. According to the National Center for Health Statistics; tibia, fibula and ankle fractures account for an annual sum of 581,000 fractures. Of all long bone fractures, the tibia is the most common site for non -union(failure to heal).
For many years, the standard practice in the treatment of fractures of the tibia shaft and other long bones has been intramedullary nailing (placing rod in the bone)using titanium or stainless steel implants( tibial nails).
More recently however, orthopaedic surgeons have found an alternative to the standard carbon fiber implants (tibial nails), especially in the prophylactic reinforcement of bones susceptible to pathological fractures following metastatic tumors. The new carbon fiber has also been used in the treatment of tibial non-union (non- healing bone); which has shown satisfactory outcomes. A clear advantage over titanium implants (tibial nails) is the carbon fiber's radiolucent (ability to see through the implant on x-ray) property. This allows for improved visualization of early healing and the reduction of fracture segments (i.e. fracture alignment) without the typical radiopaque (inability to see through the implant on x-ray) density and artifact found with metals on x-ray, MRI or CT Scans. The early visualization of callus formation8(healing) may therefore serve as a good prognostic predictor of successful union.
Thus orthopaedic trauma patients, especially in cases of polytrauma may heal faster; attain earlier weight bearing status, and independence, decrease rehabilitation center stays and advance recovery with possible quicker return to work. These benefits have economic significance in reducing direct costs to patients and their families as well as to the healthcare system. Use of carbon fiber implants (tibial nails) seems to hold the promise of a shorter recovery time with better functional outcome than with more rigid titanium implants (tibial nails). This is due to the carbon fiber implants(tibial nails) elasticity (flexibility) which is close to that of bone, preventing excessive rigidity and possible non- union (non -healing bone).
Intramedullary nails have continued to evolve, beginning with stainless steel implants and progressing to titanium. The titanium nail has been used over several years and the carbon fiber is a newer material and is now used by several institutions for treatment of tibial shaft fractures. There are no studies that directly compare the two nails in a prospective manner.
