Materials and methods The reconstructed site was the humerus in 15 cases, the radius, the ulna or the wrist joint in 22 cases, carpal or metacarpal bone in 52. The etiologies consisted of three traumatic bone defects, 13 traumatic nonunions of long bone, two osteonecroses of the humeral head, eight osteomyelitis, nine case after resections of bone tumor, two congenital pseudoarthroses of the ul...

This article describes a technique to predictably reconstruct both horizontal and vertical bony defects with one graft, the autogenous J-graft. Bone harvested from the ramus is contoured in three dimensions resulting in both a horizontal and a vertical component. When there is inadequate soft tissue due to the increase in bone volume at time of augmentation, the bone graft is combined with a pe...

Background: Cranioplasty (CP) is a neurosurgical procedure performed after decompressive craniectomy using autologous bone graft or various artificial materials. Aim: To find differences in complications between patients who underwent CP an flap versus titanium mesh as well to identify significant risk factors for post-CP Study Design: Comparative cross-sectional study. Methodology: A total of ...

Method In the period 2011-2014, we performed allogeneic bone graft transplantation in 10 patients with extensive poststernotomy defect of the chest wall. In 9 cases we used sternal graft, while in 1 case calva bone graft was used. Prior to the transplant, each patient underwent vacuum assisted closure treatment of the wound and general antibiotic therapy. Thorax and the graft stabilization was ...

We have recently witnessed a rapid expansion of commercially available bone grafting options that have primarily been introduced for use in the lumbar spine in addition or as an alternative to iliac crest bone graft (ICBG). Arguably, these options can shorten operative times by obviating the need for iliac crest bone grafting, while also decreasing the subsequent morbidity associated with harve...

Graft necrosis following ACL reconstruction is often associated with the use of autologous grafts. Host cells rather than graft cells contribute to the repair of the tendon-bone interface and the remodeling of the autologous graft. The native tendon-bone interface is not recreated and the biomechanical properties are not restored back to native values. We examined the effects of introducing gap...

Bone regeneration procedures require alternative graft biomaterials to those for autogenous bone. Therefore, we developed a novel porcine graft using particle sizes of 250–500 μm and 500–1000 μm in rabbit calvarial bone defects and compared the graft properties with those of commercial hydroxyapatite (HA)/beta-tricalcium phosphate (β-TCP) over eight weeks. Surgery was performed in 20 adult male...

INTRODUCTION Interference screws used in fixation of anterior cruciate ligament (ACL) hamstring grafts create mechanical hold by forcing the graft into frictional contact with the bone tunnel. We analyzed the resultant graft-tunnel contact pressure using an in vitro model of human cadaver 8mm hamstring grafts. METHODS Contact characteristics were assessed using both pressure sensitive films a...

OBJECTIVES The purpose of this study was to evaluate the sinus bone graft resorption over 3 years after two-stage implant placement. MATERIALS AND METHODS The subjects for this study included 30 patients whose maxillary posterior ridges were too atrophic for implants. Bone-added osteotome sinus floor elevation was used in 15 maxillary sinuses, while the bone graft by lateral approach techniqu...

Bone is the second most common transplant tissue after blood, with the iliac crest autologous graft being most used. Bone transplantation induces osteogenesis to repair bone defects. Despite being the most efficient, autogenous bone requires an additional incision and its supply may be inadequate. Deepfrozen allogeneic bone can be an alternative, but is at risk of microbiological contamination,...
