OBJECTIVE This report focuses on the biological events occurring at various intervals following autogenous bone grafting of large-volume defects of the knee joint's femoral condyle secondary to osteochondritis dissecans (OCD) or osteonecrosis (ON). It was hypothesized that the autogenous bone graft would integrate and the portion exposed to the articular surface would form fibrocartilage, which...

Tensile stress and tensile strain directly affect the quality of nerve regeneration after bridging nerve defects by poly(lactic-co-glycolic acid) conduit transplantation and autogenous nerve grafting for sciatic nerve injury. This study collected the sciatic nerve from the gluteus maximus muscle from fresh human cadaver, and established 10-mm-long sciatic nerve injury models by removing the isc...

Alveolar bone defects are conditions that impede the progress of orthodontic treatment. This study compared the mechanics of the healing of autogenous intramembranous (IM) bone grafts and grafts comprising a mixture of IM and demineralised bone matrix of autogenous intramembranous origin (DBMIM), in an attempt to determine the reliability of each material. Thirty-two New Zealand white rabbits h...

For the reconstruction of extensive craniofacial bony defects, autogenous bone is the material of choice because of its potential for revascularization and its osteoconductive and osteoinductive properties. In the present study, the results obtained after grafting with autogenous bone grafts in 233 patients with facial bony defects are analyzed retrospectively. At the Department of Maxillo-Faci...

Highlights The article outlines the modern concept of arterial myocardial revascularization, presents most promising directions for development coronary surgery, and describes results prospects clinical application autogenous grafts using two internal thoracic arteries in various graft configuration situ, making it possible to assess effectiveness procedure. Abstract There are many approaches a...

OBJECTIVE To assess the clinical outcome of crushed cartilage grafts used to conceal contour irregularities in rhinoplasty. METHODS We reviewed the medical records of 462 patients in whom crushed autogenous cartilage grafts were used, selected from a total of 669 patients in whom rhinoplasty procedures were performed at our institution between June 1, 1999, and June 1, 2006. The grafts were u...

Numerous studies have been carried out to determine the effect of various types of bone transplants on the healing pattern of experimentally produced defects in animals (Maatz, Lentz and Graf 1954; Burwell 1963; Heipel, Chase and Herndon 1963; Melcher and Irving 1963; Buring and Urist 1967; Raina 1968). These have repeatedly shown that autogenous bone grafts are better than homogenous and heter...

Autogenous bone grafts from the iliac crest have long been the gold standard for repair and reconstruction of bone; however harvesting of the grafts from the iliac crest is associated with donor site morbidity, particularly chronic pain. The bone morphogenetic proteins (BMPs) are soluble bone matrix glycoproteins that induce the differentiation of osteoprogenitor cells into osteogenic cells and...

Surgical, medical, and prosthodontic records of 61 consecutively treated patients with mandibular discontinuity were reviewed retrospectively. All 61 patients had undergone discontinuity reconstruction with autogenous bone grafts; 31 of 61 had also received endosseous dental implants and a dental osseoprosthesis. Of these 31 implant-reconstructed patients, 23 had free autogenous nonvascularized...
