Background: There are multiple methods for acceleration of bone healing. Bone marrow has been shown to contain osteoprogenitor cells. Objective: To determine the effect of percutaneous bone marrow injection on bone healing. Methods: 15 mature, 2-kg-weighing white New Zealand rabbits from both sexes were randomized into 3 groups: Group I: Only osteotomy of right radius was performed and a 5 mm b...

Objectives- To assess the ectopic bone formation in canine masseter muscle following the implantation of the natural bovine bone minerals (NBM) loaded with canine mesenchymal stem cells (MSCs).Design- Experimental study.Animals- four mongrel dogs.Procedures- Tripotent MSCs isolated from the canine bone marrow were loaded onto the NBM sponges and allowed to adhere. The cell-loaded scaffolds were...

background: in several conditions we have face cranial bone defects. reconstruction of these defects remains one of the most challenging problems encountered by craniofacial surgeons.   objective: to evaluate bone repair in cranial bone defects by use of an implant made of octacalcium phosphate in combination with bone matrix gelatin (ocp/bmg).   methods: we used 40, 5–6-week-old male sprague-d...

we report a three-phase bone scintigraphy for the diagnosis of a peripheral bone lesion caused by systemic sarcoidosis. a 32-year-old man with suspected osteomyelitis of the right forefinger underwent three-phase bone scintigraphy with tc-99m hydroxymethylene diphosphonate (hmdp) and single-photon emission computed tomography/computed tomography (spect/ct). the lesion was rich in blood flow acc...

  Chronic recurrent multifocal osteomyelitis (CRMO) is a rare aseptic, auto-inflammatory bone disorder. CRMO presents with bone pain with or without fever. The diagnosis of CRMO is a diagnosis of exclusion and should be included in the differential diagnosis of chronic inflammatory bone lesions in children. Cultures of the bone are typically sterile, antibiotic therapy does not result in clinic...

Avascular necrosis of the femoral head (ANFH) is a pathologic process that results from interruption of blood supply to the femur bone resulting in the death of bone cells and collapse of the femoral head. Nontraumatic ANFH continuesto be a significant challenge to orthopedic surgeons. While the exact mechanisms remain elusive, many new insights have emerged from research in the last decade tha...

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...
