We describe a new technique of reconstruction of the deficient acetabulum in cementless total hip arthroplasty. The outer iliac table just above the deficient acetabulum is osteotomised and slid downwards. We have termed this an iliac sliding graft. Between October 1997 and November 2001, cementless total hip arthroplasty with an iliac sliding graft was performed on 19 patients (19 hips) with a...

BACKGROUND One of the main reasons why the breast fat grafting was questioned is that there may be lipofilling resorption. In the literature, the resorption rate reported over the 1(st) year is highly variable (20-90%). OBJECTIVE The aim of this work was to identify the biochemical and clinical parameters, which increase fat graft maintenance in breast reconstruction. MATERIALS AND METHODS ...

PURPOSE Bioactive glass bonds to bone through a calcium phosphate layer that mimics the structure of the mineral phase of bone. Formation of this layer is inhibited in the presence of serum protein. The authors hypothesize that creation of a calcium phosphate layer on the surface of bioactive glass before implantation will enhance bone regeneration and graft material resorption in bone defects....

Forty cases of congenital pseudarthrosis of the tibia were reviewed. The results were assessed so as to emphasise function rather than simply the presence or absence ofunion. At the time ofreview, 14 patients had undergone amputation; eight others had non-union or tenuous union. No surgical procedure except the Farmer operation (a composite skin and bone pedicle graft from the other leg) showed...

Seven patients with a bone tumor were operated on with local excision and a free vascularized fibular graft. Four of the patients received both chemotherapy and radiotherapy. The blood flow in the grafts was evaluated by scintigraphy within 1 week after the operation. The median follow-up time was 4 (1-5) years. All but one graft-host junction healed primarily. There were 5 graft fractures in 3...

This prevents graft resorption by inducing vascularization and provides growth factors, it is a two-step procedure. The first step includes an extensive excision of infected and non-viable tissue, it is followed by careful stabilization of the bone and placement of cement spacer in the bone defect .and...

This case report documents the first use of particulate autogenous bone graft with the corticotomy-assisted rapid orthodontic procedure known as periodontally accelerated osteogenic orthodontics (PAOO). A 41-year-old man, with class II, division 2 crowded occlusion, was treated with the PAOO procedure. Buccal mucoperiosteal flaps were reflected, and selected vertical and horizontal corticotomy ...

Two bone graft extenders differing in chemical composition were implanted contralaterally in 27 consecutive patients undergoing instrumented posterolateral lumbar fusion as standard-of-care. Bone marrow aspirate and autogenous bone graft were equally combined either with β-tricalcium phosphate (β-TCP) or a hybrid biomaterial [containing hyaluronic acid (HyA) but lacking a calcium salt] and impl...

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 ...

The review is based on the analysis of 53 literature sources from PubMed, Google, Google Scholar, and Cochrane Library. Among substitutes for autogenous bone grafts in spine surgery, ceramic biomaterials are largest studied group, among which certain niche occupied by calcium phosphate ceramics (CPCs). Hydroxylapatite, tricalcium biphasic with all parts hydroxylapatite widely used surgery. adva...
