BACKGROUND An increased rate of pseudarthrosis has been documented following posterolateral lumbar spine grafting in patients who smoke. This same relationship has been assumed for anterior cervical interbody grafting, but to our knowledge it has never been proven. This study compared the long-term radiographic and clinical results of smokers and nonsmokers who had undergone arthrodesis with au...

Background: The purpose of this retrospective study was to analyze the long-term results of revision ORIF, jointcontracture release, and autogenous bone-grafting in the treatment of distal humerus frac-ture nonunions in older agedpatients with poor bone quality or bone loss who would have been candidates for total elbow arthroplasty.Methods: Seven patients (average age at inde...

The use of titanium mesh for localized alveolar ridge augmentation was evaluated by clinical, radiographic, laboratory, and histologic-histomorphometric evaluation. Seventeen patients participated in this study. All patients required localized alveolar ridge augmentation before placement of dental implants. An equal mixture of autogenous bone graft and inorganic bovine mineral (Bio-Oss) was use...

INTRODUCTION Reconstructive septorhinoplasty in complex nasal deformities often requires harvesting a large amount of tissue for grafting. Autogenous septal cartilage has generally been considered the gold standard grafting material. The aim of this paper was to report our experience with the use of costal cartilage grafts in cases with significant structural deformities and insufficient septal...

The study was designed to exploit the single photon emission computerized tomography (SPECT) to compare osteoblastic activity of two implant systems: an Endopore implant (Beaded implants) placed immediately into an extraction socket in conjunction with peri-implant autogenous grafting supplemented with a guided tissue regeneration (GTR) technique, and an Endopore implant placed immediately into...

Many bone grafting techniques have been used to reconstruct the partially dentate and edentulous mandible. This article discusses the various bone grafting techniques to reconstruct mandibular defects. Also included are issues such as whether autogenous bone is necessary for reconstruction of the mandibular ridge and the importance of membranes.

PURPOSE Implant placement in the posterior maxilla may often be contraindicated because of insufficient bone volume and the presence of the maxillary sinus. In these situations, sinus floor lifting and grafting frequently have been proposed as the best treatment. The aim of this study was to compare histologically the use of 100% autogenous bone versus a combination of autogenous bone and corti...

Several million people suffer from joint cartilage damage with very debilitating conditions. Once damaged, cartilage is a tissue that does not restore itself. Techniques such as micro-fracture, autogenous or allogenous osteochondral transplantation, and autologous chondrocyte implantation may be done to repair cartilage and relieve the patients’ symptoms. The environmental factors’ effect on th...

Articular cartilage is composed of chondrocytes and matrix, and it is diffi cult for cartilage to heal after injury. In 1743, Hunter had stated that, “cartilage once destroyed is never recovered.” This was true until 2003, when Koshino and colleagues reported regeneration of degenerated articular cartilage after high tibial valgus osteotomy for medial compartmental osteoarthritis of the knee. I...
