Autologous Bone Graft in Foot and Ankle Surgery
Bone graft is a common adjunct procedure in orthopedic surgery used for fusions, fracture repair, and the reconstruction of skeletal defects in the foot and ankle. Autologous graft, or autograft, involves the transport of bone from a donor site to another location in the same patient. It is considered by many to be the gold standard of bone grafting, as it is provides all biologic factors required for functional graft. Further, autograft is 100% histocompatible with no risk of disease transmission.
CONCLUSION: The future of organ bioengineering relies on furthering understanding of organogenesis, in vivo regeneration, regenerative immunology and long-term monitoring of implanted bioengineered organs. PMID: 32463143 [PubMed - in process]
Conclusions. Chronic airway injury and dysregulated repair programs are evident in airway epithelium obtained from patients with BOS, particularly with SAEC. We also show that azithromycin partially mitigates this pathology.
Conclusions: Radiographic recovery of cortical and cancellous bone defects was achieved with high probability via refilling with HAp/Col composite over the 1-year period. PMID: 32429017 [PubMed - as supplied by publisher]
Abstract Acellular nerve allografts (ANAs) are increasingly used to repair nerve gaps following injuries. However, these nerve scaffolds have yet to surpass the regenerative capabilities of cellular nerve autografts; improved understanding of their regenerative mechanisms could improve design. Due to their acellular nature, both angiogenesis and diverse cell recruitment is necessary to repopulate these scaffolds to promote functional regeneration. We determined the contribution of angiogenesis to initial cellular repopulation of ANAs used to repair nerve gaps, as well as the signaling that drives a significant por...
This article reviews the history of UCL repair including the rationale for the revival of interest in primary repair of the U CL as an option for the treatment of select athletes as well as the early clinical results indicating the short-term successful outcomes of the procedure in properly selected athletes.”
We present a femorofemoral bypass graft with ringed polytetrafluoroethylene (PTFE). In this occasion, revascularization was achieved by a backflow mechanism. The approach described achieved its goal of revascularizing the allograft as well as the distal extremity, with both short- and long-term successful outcomes. Benefits of this approach when compared with re-implantation or procedures directly involving the transplant renal artery include minimization of ischemic time, no need to repair the stenosis, anastomoses with vessels of greater diameter, no need to perfuse the kidney, no need to take down the renal artery anast...
AbstractAbstractWhen compared to meniscectomy, meniscus allograft transplantation (MAT) may provide superior long-term benefits to young, active patient populations who have lost meniscal function because of irreparable damage, such as, an avascular tear, previous repair failure, and unsalvageable tear types. Positive outcomes are most likely to be achieved when meniscus allograft transplantation is performed in appropriately selected patients. Indications include patients younger than 50 years of age, with a history of subtotal or total meniscectomy without concomitant articular cartilage defects, uncorrectable join...
Large bone defects occur due to trauma, bone tumor resection, infections and metabolic, degenerative or congenital diseases 1. The larger the defect, the more difficult to treat it because the damage to repair exceeds the intrinsic capacity of regeneration, leading to non-union complications2. Nearly 2 million/year of bone grafts (autografts, allografts or xenografts) are performed worldwide3 and among them, autograft is the gold standard due to its osteoinductivity, osteogenicity and osteoconductivity1,4.
In conclusion, the results of the present study demonstrated that the upregulation of miR‑155‑3p induced by puerarin promoted BMSC differentiation and bone formation and increased bone mass in rats with bone grafts, thereby supporting the potential application of puerarin in the prevention of bone graft defects.

We present our results for chronic distal biceps avulsions secured with suture button through a single transverse incision in high flexion without the need for allograft augmentation.
