Sternal non-union is a severe complication of sternotomy closure following open heart surgeries. Healing problems typically occur in 0.3% to 5% of patients. Technetium-99m methylene diphosphonate (99mTc-MDP) bone scintigraphy has been used to assess bone nonunion to predict the healing response for proper management.  In this report, we present the case of a marked sternal nonunio...

Background: Secondary alveolar bone graft has been widely used for the closure of maxillary bone defects in patients with cleft lip and palate (CLP). However, the log-term stability of grafted bone in detail remains unclear. Purpose: To evaluate the nature of longitudinal changes in the grafted bone from autogenous iliac bone in patients with CLP for more than 2 years after the surgery. Methods...

PURPOSE To evaluate the influence of bone marrow aspirate added to xenograft or alloplast graft matrix scaffold to produce bone. MATERIALS A maximum of 4 cc bone marrow was aspirated from the anterior iliac crest of 5 patients to saturate the matrix scaffold prior to bone graft. Seven graft sites evaluated included sinus lift augmentation, particulate onlay graft of the maxilla via a tunnelin...

It is well known that the periosteum is capable of bone formation. In the present study, the value of the vascularized periosteal graft in healing the long-bone defect filled with the allogenous bone graft was studied. The aim of the study was to verify the efficiency of the rotational vascularized periosteal graft as a optional surgical method as well as to prove its advantages in comparison w...

Bone transplantation as a mean to reduce the fracture healing time in large defects was attempted for the first time more than 300 years ago, with nowadays several techniques and methods of assessment of its efficacy. The bone graft was longtime thought as initiating the osteogenesis from the recipient, but new data show that cells from the graft contribute to osteogenesis and to its incorporat...

INTRODUCTION: Bone fusion, such as in spinal surgeries, may be accelerated through the use of a bone graft substitute (BGS). While autograft was considered the gold standard of treatment, it can be undesirable for use by surgeons due to donor site morbidity and limited availability. As an alternate method of treatment, human allograft Demineralized Bone Matrix (DBM) can be used by surgeons eith...

Background :
 The use of Bone Graft in the management Defect is a challenge world orthopedics. Recently, eggshell containing hydroxyapatite has become new hope an economical and efficient bone graft treatment defects. aim this systematic review was to explore available literature on clinical performance eggshells as grafts guided regeneration.
 Method Two databases (PubMed Cochrane) w...

BACKGROUND Implant surgery has become popular with the advance of surgical techniques such as sinus lifting, guided bone regeneration, and block bone graft. However, there were no data about the frequency of bone graft during implant surgery. The purpose of this study was to report the frequency and types of bone graft depending on dental implant patients' profile to complement the database reg...

This case study describes the first use of a novel nanosynthetic bone graft, OssDsign™ Catalyst, in Spinal fusion patient. new graft consists nanoscale calcium phosphate containing silicate substitution (5.8wt% silicon) which has been shown to be capable regenerating via endochondral ossification route challenging animal models [1,2], resulting high rates at very early timepoints comparable exi...
