conclusions alendronate may be considered a therapeutic option for improving the bone formation process and reducing resorption in different bone grafting procedures. further detailed studies should focus on dosage and time-dependent effects of alendronate on bone remodeling. results at 6 weeks, the bone area was significantly larger in the xenograft-alendronate group (33.0% ± 5.0%) than in the...

INTRODUCTION For access-challenged patients with bilateral upper extremity central venous stenosis, solutions include the Hemodialysis Reliable Outflow (HeRO) device or an autogenous AV fistula in the lower limb. We evaluated HeRO grafts and transpositions of the femoral vein in maintaining primary and secondary patency. METHODS We retrospectively analyzed 40 patients with a HeRO device and 1...

The aim of this experimental study was to evaluate the use of prefabricated autogenous bone grafts as onlay grafts to the mandible. Excess bone of 10 x 12 x 40 mm was produced inside blocks of pyrolyzed bovine bone under a polylactic membrane coverage on the outside of the mandible in 15 adult Göttingen minipigs. After 5 months, this bone was harvested and transferred to the premolar region of ...

Hamstring autografts in anterior cruciate ligament reconstruction have an excellent clinical track record, but some patients have hamstring tendons that yield grafts of smaller diameter, which has been shown to be a significant risk factor for worse outcomes and graft failure. Some authors have advocated augmentation with allograft in these patients. Tripling the semitendinosus yields a complet...

The cavities left after resection of bone bridges for partial closure of growth plates in children have commonly been filled with free fat grafts. Such cavities have been seen to elongate and thus enlarge during growth after the operation, but the fate of the grafts has been unknown. Similar cavities, made in the tibiae of growing pigs were filled with autogenous fat and studied by radiography ...

surgery on the skeleton frequently requires harvesting of autogenous bone graft from the pelvis, but this procedure often is complicated by problems. the purpose of this retrospective, comparative descriptive study was to compare the efficacy of metal-derived bioactive glass (novabone) versus autogenous iliac crest bone graft in adolescent idiopathic scoliosis surgery. the study was carried out...

background: considering the common origin of skin and peripheral nervous system, a tube of dermal layer of skin hypothetically can be an ideal conduit for nerve reconstruction. an experimental study performed to evaluate the nerve regeneration of efficacy into a dermal tube. methods: sixty male wistar rats were used. a 10 mm gap was produced in right sciatic nerves. in group a the autogenous ne...

Desmoid tumors are rare soft tissue tumors derived from fascia and connective tissue of the muscular layers. The abdominal region is the most frequent site of involvement, whereas involvement of sternal manubrium is rare. We report the case of a rare desmoid tumor in the sternal manubrium mimicking radiological and metabolic features of malignant tumor, which was successfully treated by sternal...

Arterial reconstructions using autogenous veins are often compromised by late graft stenoses, diffuse constrictions, and occasional aneurysmal dilatations. Comprehensive studies of alterations within vein grafts, following transplantation to the arterial circulation, are few in number. Knowledge is even more meager regarding the immediate effects of differing procurement, preparation and placem...

The American Academy of Periodontology 1 has defined marginal tissue recession as an acquired deformity with the gingival margin being located apical to the cementoenamel junction (CEJ), resulting in exposed root surface and loss of attached gingiva. Gingival recession is a common feature in populations with high as well as poor standards of oral hygiene 2 . Many factors have been proposed to i...
