BACKGROUND The management of pelvic giant cell tumors (GCTs) involving the acetabulum remains a challenge for surgeons on how to balance the relative benefits of minimizing recurrence and maintaining postoperative hip function. The present study was to present and evaluate the clinical indications, operative technique, and outcomes of pelvic GCTs involving partial acetabulum treated with multip...

Despite clinical success rates over 85%, persistent anatomic defects after rotator cuff repair are common and depend on the size of the tear repaired. The etiology of delayed or failed tendon to bone healing is multifactorial and biologic augmentation of a rotator cuff repair would be clinically desirable. Autogenous platelets contain many growth factors and are critical in the physiology of bo...

BACKGROUND Improvement of the healing process to provide better aesthetical and functional results continues to be a surgical challenge. This study compared the treatment of skin wounds by means of conducted healing (an original method of treatment by secondary healing) and by the use of autogenous skin grafts. MATERIAL AND METHODS Two skin segments, one on each side of the dorsum, were remov...

The problems of repair and grafting of tendons have received considerable attention. However, conclusions have been hampered by lack of a standard terminology and by attempts to assign the origin oftendon, paratenon, and cicatrix to distinct types ofcell. The potentialities of cells under stress have been insufficiently recognised. Beltzow (1883), Viering (1891), Busse (1892), Rehn (1919) and S...

PURPOSE To evaluate bone healing in the extraction socket of the feline maxillary canine tooth after grafting. METHODS Eighteen adult cats were submitted to unilateral extraction of maxillary canine tooth and divided into three groups. In group 1 (n=6), control, the extraction socket was left empty. In group 2 (n=6), the extraction socket was filled with autogenous cancellous bone from the il...

BACKGROUND Improvement of the healing process to provide better aesthetical and functional results continues to be a surgical challenge. This study compared the treatment of skin wounds by means of conducted healing (an original method of treatment by secondary healing) and by the use of autogenous skin grafts. METHOD Two skin segments, one on each side of the dorsum,were removed from 17 rabb...

Segmental bone allografts are widely used in managing large cortical defects. To improve host-graft union, the effect of allograft on a tibial defect augmented with non-vascularized periosteal flap was studied. Twelve mature Australian white rabbits (Oryctolagus cuniculus) were divided into intervention groups and control group. Bone defects treated segmental wrapped flap. The group transplanta...

Cracks in concrete structures can serve as pathways for aggressive chemical substances that lead to a progressive deterioration of the cement stone well reinforcement, affecting load capacity, service life and useability structures. However, reinforced exhibit an intrinsic ability heal cracks, defined autogenous self-healing. This effect includes precipitation calcium carbonate presence water C...

The demand for more sustainable building materials has led to the development of systems with self-repairing properties. self-healing technology been shown be effective in concrete and mortars, however, this is not often studied grouts. Cementitious can show an autogenous healing, i.e., intrinsic ability repair microcracks by themselves. This type healing improved addition crystalline admixture...

The aim of the present clinical study was to determine, through histologic and histomorphometric investigations of human bone specimens, whether the addition of autogenous bone to the bone substitute material Bio-Oss can produce a high-quality implant site. To improve vertical bone height, 13 sinus floor elevations were carried out in a total of 12 patients. Augmentation of the maxillary sinus ...
