UNLABELLED The aim of the present study is to compare the histological aspects of bone formation in atrophic posterior mandibles augmented by autologous bone block from chin area with corticocancellous bone block allograft used as inlays with the sandwich technique. MATERIALS AND METHODS Sixteen patients with bilateral partial edentulism in the posterior mandible were selected. The residual b...

We report the clinical and radiographic outcomes and complications of revision surgery using a cementless interlocking stem with an allograft-prosthesis composite (APC). This study included 11 patients with an average follow-up of 73 years. Of the 11 revisions, 1 was aseptic, 7 were septic, and 3 were periprosthetic femoral fractures. The mean Harris hip score improved from 25.6 points before s...

BACKGROUND AND PURPOSE Impacted morselized allograft bone is a well-established method for reconstructing bone defects at revision surgery. However, the incorporation of bone graft is not always complete, and a substantial volume of fibrous tissue has been found around grafted implants. We hypothesized that rinsing the bone graft may improve graft incorporation by removing the majority of immun...

This retrospective case series reports on the use of a new allograft bone product composed of a 70 to 30 ratio of mineralized to demineralized cortical bone particles to preserve the alveolar ridge dimensions of patients requiring tooth extraction with plans for future dental implant placement. Ten patients received atraumatic tooth extractions with subsequent placement of the blended bone allo...

PURPOSE The aim of the present study was to evaluate the effectiveness of using a mineralized bone cortical allograft (MBCA), with or without a resorbable collagenous membrane derived from bovine pericardium, on alveolar bone remodeling after immediate implant placement in a dog model. METHODS Six mongrel dogs were included. The test and control sites were randomly selected. Four biradicular ...

A two-stage procedure was carried out on 57 patients with confirmed infection in a hip replacement. Allograft bone was used in the second stage. Pathogenic organisms were identified in all patients. In stage 1, the prosthesis was removed together with infected tissue. Antibiotics were added to customised cement beads. Systemic antibiotics were not used. At the second stage, 45 of the patients h...

Benign bone tumors are commonly diagnosed and treated. Following tumor removal, the defect in the bone can be filled with auto- or allografts, (degradable) bone substitutes or non-degradable polymethylmethacrylate. The ideal substitute for this purpose should provide immediate structural support and readily incorporate into bone over a short period of time. Experimentally, microparticulate allo...

Background: There is no consensus regarding the best method of reconstruction in pediatric population following thewide resection of malignant bone tumors. More exploration of the complications of osteoarticular reconstruction leads toless existing controversy of this type of reconstruction, which is the main point of this article.Methods: Long-term outcomes and complications of osteoarticular ...

The role of arthroscopic surgery for the treatment of various orthopedic pathologies has greatly improved during the last years. Recent publications showed that benign bone lesion may benefit from this minimally invasive surgical method, in order to minimize the invasiveness and the period of immobilization and to increase visualization. Unicameral bone cysts may be adequately treated by minima...

Reconstruction with massive bone allograft and autologous vascularised fibula combines the structural strength of the allograft and the advantages of fibula's intrinsic blood supply. We retrospectively analysed the outcome of twelve patients (4 male, 8 female) who received reconstruction with massive bone allograft and autologous vascularised fibula after tumour resection in lower limb. Mean ag...
