Autologous or allograft bone grafting is commonly used for bone restoration in the setting of revision anterior cruciate ligament (ACL) reconstruction owing to bone loss or malpositioned or osteolytic tunnels. For significant defects, staged procedures with initial bone grafting to the femoral and/or tibial tunnels is occasionally required. In this setting, allograft shows variable rates and quality of healing and can incur increased expense. Historical techniques of autograft harvest are associated with limited graft volume and donor-site morbidity. Our technique of retrograde femoral autograft harvest shows excellent volume and quality of graft; minimal morbidity; operative expediency; and rapid, quality tunnel filling to facilitate an anatomic second-stage revision ACL reconstruction. Intramedullary bone graft harvest using a Reamer-Irrigator-Aspirator has shown efficacy for typical use in the setting of nonunion, particularly among orthopaedic trauma surgeons. Advantages of using the RIA 2 (Reamer-Irrigator-Aspirator) system (DePuy Synthes) for autologous bone graft harvest include lower donor-site morbidity, greater bone graft volume, decrease in number and size of incision sites, shorter harvest time, and efficacious healing. The goal of this procedure is to obtain an adequate amount of autologous bone graft using a minimally invasive device, RIA 2, safely and efficiently for a 2-stage revision ACL reconstruction.

Radiological accidents/incidents are common with nearly 400 reported since 1944 exposing about 3000 people to substantial doses of ionizing radiations with 127 deaths. Damage to hematopoietic stem and progenitor cells with resulting bone marrow failure is a common consequence of exposure to whole body acute high-dose and -dose-rate ionizing radiations and is termed hematopoietic-acute radiation syndrome, or H-ARS. Therapy of H-ARS includes transfusions, anti-bacterial and -viral drugs, molecularly-cloned hematopoietic growth factors and hematopoietic cell transplants.

Background: Eden-Hybinette procedure can maximize the restoration of the glenoid defect by harvesting a proper size of iliac bone block. We developed an arthroscopic "double-inlay" Eden-Hybinette procedure to achieve better bone union of the graft. The aim of this study was to evaluate the clinical and radiological mid-term outcomes of the arthroscopic "double-inlay" Eden-Hybinette procedure for bone defects exceeding 20%.

Periprosthetic complications after trapeziometacarpal arthroplasty mostly require revision surgery to restore function. An unstable cup in the trapezium is typically surgically managed by trapeziectomy. This report highlights a possible alternative to maintain the implant by reconstruction of the trapezium with corticocancellous autograft.

Objective: The goal is to analyze the osteogenesis potential of polymethylmethacrylate (PMMA)-hydroxyapatite (HA) and stem cells from human exfoliated deciduous teeth (SHED) as a biomaterial candidate for alveolar bone defect therapy through a bioinformatic approach within an study.
Materials And Methods: Three-dimensional (3D) ligand structures consisting of HA, PMMA, and target proteins of SHED were obtained from the PubChem database. STITCH was used for SHED target protein analysis, STRING was utilized for analysis and visualization of protein pathways related to osteogenesis, PASS Online was employed to predict biological functions supporting osteogenesis potential, PyRx 0.

Objectives: The ultimate goal of stem cell (SC) transplantation is the regeneration of salivary gland function by transplanted SCs differentiating into salivary gland cells. Therefore, this study aimed to evaluate the regenerative capacity of bone marrow-derived mesenchymal stem cells (BM-MSCs) transplantation in irradiated mice using the immunohistochemical markers Ki-67 and CD34.
Material And Methods: Four groups of male mice were included in the study.
