An animal study is presented, evaluating a method of mandibular reconstruction using a poly(D,Llactide) (PDLLA) scaffold. Six goats underwent a continuity resection of the mandibular angle. The defect was bridged with a preshaped PDLLA scaffold, filled with an autogenous particulate bone graft from the anterior iliac crest, and fixed with two preshaped titanium plates. To accelerate bone healin...

Introduction: Anterior corpectomy with instrumentation and fusion is common in the treatment of fractures, tumors, infections, and kyphotic deformities of the thoracic and lumbar spine. Both autogenous (iliac crest, rib or fibula) as well as allogenous strut grafts are utilized in the reconstruction. One of the advantages of autogenous bone is thought to be the endogenous cells and growth facto...

INTRODUCTION Bone grafting is an integral part of orthopaedic surgery; the use of bone graft is increasing consistently in traumatology and also in complex revision surgeries of hip and knee arthroplasties. Considering this fact there is a need for some way to find solution for a bone graft which has more osteoinduction, osteoconduction as well as osteogenecity and also reduced rates of graft r...

Distal biceps brachii tendon ruptures occur much less frequently than do their proximal counterparts. Distal tendon ruptures usually are associated with considerable function deficits and may require surgical treatment. Repair of chronic distal biceps brachii ruptures are extremely unusual. A free autogenous semitendinosus tendon graft was used to reconstruct the distal biceps tendon by reattac...

OBJECTIVES To determine whether autogenous tissue-engineered cartilage grafts can be synthesized in predetermined shapes, to compare tissue-engineered cartilage with native cartilage with respect to histological characteristics and biomechanical properties, and to demonstrate how multiple transplantations affect tissue-engineered cartilage. DESIGN Controlled, prospective animal study. SUBJE...

BACKGROUND With the increasing use of hydroxyapatite orbital implants, the complication of exposure has become apparent to oculoplastic surgeons. Many kinds of patch grafts, such as sclera, dermis, and hard palate mucosa, have been used to cover exposed hydroxyapatite implants with inconsistent results. In this study, the authors use a newly developed technique, autogenous retroauricular myoper...

INTRODUCTION Ankylosis may be defined as the fusion of the articular surfaces with bony or fibrous tissue. The treatment of temporomandibular joint ankylosis poses a significant challenge because of the high incidence of recurrence. PURPOSE To report 15 cases treated by either gap arthroplasty, or the articular reconstruction technique using costochondral grafts, coronoid process grafts or al...

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...

This report describes treatment of a patient using vertical alveolar ridge augmentation performed prior to transposition of the inferior alveolar nerve (IAN). A preoperative computerized tomographic (CT) scan revealed 2 to 3 mm of bone above the canal in the left mandibular molar region. An autogenous bone graft harvested from the chin area was utilized along with a titanium mesh for vertical a...

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...
