Put Your Back Into It: A Structural and Mechanical Characterization of Iliac Crest and Cervical Spine Autograft for ACDF Surgeries
… worldwide. ACDF utilizes autologous bone graft (autograft) from the iliac crest to induce fusion between neighboring vertebrae following the procedure. The iliac crest is widely considered the gold-standard autograft for ACDF procedures due to its osteoinductive, osteoconductive, and …

Enhancing bone healing through concurrent anabolic- and anti-catabolic pharmacological treatment
… is known to heal in only 60 %. In study 1, autograft was compared with autograft+BMP-7 and autograft+BMP-7+ZOL with the hypothesis that the latter treatment would lead to superior healing compared with the others. All three treatments increased the healing rate from 60 % to 100 %. The …

In vivo bone formation using Adipose Derived Stromal Stem Cells. The histomorphometry of the ovine defect model
… of 7 treatment groups was examined: 1. “Bone autograft/ADSCs”, 2. “Bone autograft/BMSCs”, 3. “ProOsteon 200R/ADSCs”, 4. “ProOsteon 200R/BMSCs”, 5. “Bone autograft”, 6. “ProOsteon 200R” and 7. “Empty defect”. The time-points were: 2, 4, 8 and 12 weeks. The analysis of the harvested specimens …

KERATIN BIOMATERIAL SCAFFOLDS FOR PERIPHERAL NERVE REGENERATION
… "gold standard" for nerve transection injury, autograft, has many limitations. Nerve conduits are used as an alternative to autograft surgery but they are currently recommended for the repair of small defects (≤ 3cm) in small diameter sensory nerves only. Use of filler materials inside the …

Effects of Electrical Stimulation and Testosterone in Translational Models of Peripheral Nerve Injury
… injury was compared to a surgery mimicking an autograft procedure of the sciatic nerve (double transection-repair). Adult male rats were divided into four experimental groups: sciatic crush, sciatic crush with ES+TP treatment, sciatic transection-repair (autograft), and autograft with ES+TP. …

Peripheral nerve regeneration through collagen devices with different in vivo degradation characteristics
… and sensory capability is limited following autograft, the most common procedure for peripheral nerve repair. Tubulation repair of a transected peripheral nerve presents an alternative to autograft, but has not yet shown the ability to satisfactorily restore lost function. A variety of …

Electrospun Blends of Polydioxanone and Fibrinogen for Urological Applications
… and organ replacements cannot be satisfied by autograft and allografts alone. The purpose of this study was to investigate the feasibility of electrospinning a blend of polydioxanone and fibrinogen to produce an engineered tissue scaffold. Fiber diameter and pore size of blends were …

The management of acute knee dislocations: a global survey of orthopaedic surgeons' strategies
… management and delayed reconstruction with autograft (p<0.05) if surgery was necessary. Surgeons from DEN favoured early, single stage arthroscopic ligament reconstruction. Significantly more EMDN surgeons preferred clinical examination (p<0.05) and duplex doppler scanning (p<0.05) compared …

Towards an autologous tissue engineering construct for craniofacial bone repair
… healing without clinical intervention. The autograft is the current standard of care for repair of these defects due to capacity for osteointegration and immunological compatibility. However, potential limitations, such as donor site morbidity, have motivated the development of alternative …
