Peripheral nerve injury is an important cause of disability, that can hinder significantly sensory and motor function. The clinical gold standard for peripheral repair the use autografts, nevertheless, this method has limitations such as donor site morbidity. An emerging alternative to autografts are guide conduits, which used entubulate severed provide guidance directed regeneration tissue. Th...

The present paper reports on three patients who underwent localized alveolar ridge augmentation using block autografts harvested from the mandibular tori. Autogenous particulate bone graft was placed at the periphery of the block. Resorbable collagen membrane was placed above the graft material. Implant placement surgery followed at 6 to 16 months after bone grafting. During implant surgery, a ...

Prospective studies were done to determine the outcome of allografts and autografts used for revision anterior cruciate ligament reconstruction. The allograft group was comprised of 65 patients observed for a mean of 42 months postoperatively; the autograft (bone-patellar ligament-bone) group contained 20 patients observed for a mean of 27 months postoperatively. KT-2000 testing and a comprehen...

BACKGROUND Standard compression therapy for venous ulcers of the legs does not promote healing. Although autografting accelerates tissue repair, it is difficult to use in patients with concomitant diseases or when multiple grafts are required. The amniotic membrane has been used as a covering material and promotes epithelialization, making it a good potential treatment option when autografts ar...

PURPOSE As alternatives to nerve grafts for peripheral nerve repair, we have synthesized 12 mm long poly(2-hydroxyethyl methacrylate-co-methyl methacrylate) (PHEMA-MMA) porous tubes and studied their regenerative capacity for the repair of surgically-created 10 mm rat sciatic nerve gaps. We compared the in vivo regenerative efficacy of these artificial tubes with the gold standard, the nerve au...

Bone defects in revision hip surgery can be reconstructed with impacted morselized bone grafts. Rinsing these trabecular allografts may enhance graft incorporation by washing out immunogenic factors present in blood, marrow, and fat. However, it has been proposed that impaction of the graft releases biologically active factors, which can provide sufficient activity to stimulate new bone formati...

The local immunoreactivity of C-reactive protein (CRP) was studied in a heterotopic porcine model of posttranplant obliterative bronchiolitis (OB). Bronchial allografts and control autografts were examined serially 2-28 days after subcutaneous transplantation. The autografts stayed patent. In the allografts, proliferation of inflammatory cells (P < .0001) and fibroblasts (P = .02) resulted in o...

Osseous grafting represents one mode of therapy to manage periodontal osseous defects. Materials for osseous grafting can be obtained from the same person (autografts), from a different person of the same species (allografts), from a different species (xenografts), or from synthetic materials (alloplasts). The two types of grafts most frequently used in periodontal therapy are autogenous grafts...

LEARNING OBJECTIVES After reading this article, the participant should be able to: 1. Understand the challenges in restoring volume and structural integrity in rhinoplasty. 2. Identify the appropriate uses of various autografts in aesthetic and reconstructive rhinoplasty (septal cartilage, auricular cartilage, costal cartilage, calvarial and nasal bone, and olecranon process of the ulna). 3. Id...
