Background: Non-united fracture shaft of the femur after plate fixation is a common problem. Management this problem still controversial. There are many methods for treating femoral aseptic nonunions with broken implant which conversion to reaming solid intramedullary nail one procedures. However, reported success rate varies. This study aimed evaluate bone healing, especially callus formation,...

Neuronal activity in the hyperstriatum ventrale, pars caudale (HVc) is associated with and necessary for the production of song by songbirds. HVc neurons also respond to acoustic stimuli. The present investigation assessed the auditory response properties of neurons in HVc by testing with the individual bird's own (autogenous) song and the songs of conspecific birds. Throughout HVc, multiunit c...

OBJECTIVES This study was undertaken to evaluate the effect of hyperbaric oxygen (HBO) on the repair of critical-sized defects in the presence and absence of a nonvascularized autogenous bone graft. STUDY DESIGN Ten New Zealand White rabbits were randomly divided into 2 groups of 5 animals each. Bilateral 15-mm calvarial defects were created in the parietal bones of each animal, resulting in ...

Micro cracks occurring in concrete around tensile rebar is well known latent damage phenomenon. These micro cracks develop, and can be detected after reaching the surface of the concrete. Detection of these cracks before they are fully formed is preferable, but observing the whole crack structure is difficult. Another problem is repairing micro cracks under the concrete surface. The autogenous ...

BACKGROUND AND PURPOSE Open-wedge osteotomies of the distal radius create a void that is usually filled with either iliac crest bone graft or bone substitute. Previous studies have suggested that this is unnecessary. We investigated the safety of omitting the filling procedure. PATIENTS AND METHODS We included 15 patients with a dorsal malunion of a distal radius fracture. A palmar approach a...

A pleasing smile involves a harmonious relationship among the teeth, the gingival scaffold and the lip framework. In dental profession, aesthetics of the patient is the main factor to be focused on along with treating the disease of the patient. The primary goal of esthetic dental treatment is the restoration to a natural, healthy, and esthetic appearance from an otherwise damaged dentition [1]...

Strain hardening cementitious composite (SHCC) is a special class of ultra-ductile material which has autogenous self-healing capability due to its intrinsic tight crack widths. To further improve healing ability, agent (HA) can be incorporated in SHCC, enabling it also the autonomous mechanism. In this study, effects adding bacteria-embedded polylactic acid (PLA) capsules on mechanical propert...

Autogenous bone grafting, used to repair bone defects, is limited and the donor site can experience complications. Compared to autogenous bone graft, artificial bones have different porosity, which might make them suitable alternatives to bone grafts. Here, two porous biphasic calcium phosphate bone substitutes, namely Bicera™ and Triosite™, are used in an animal study and clinical practice to ...

We previously showed that cartilage tissue can be engineered in vitro with porcine chondrocytes and gelatin/chondoitin-6-sulfate/hyaluronan tri-copolymer which mimic natural cartilage matrix for use as a scaffold. In this animal study, 15 miniature pigs were used in a randomized control study to compare tissue engineering with allogenous chondrocytes, autogenous osteochondral (OC) transplantati...

To assess results of operative treatment of non union fracture shaft of Tibia by intramedullary interlocking nail augmented with autogenous cancellous bone graft in our setup. A total of 25 nonunion tibial shaft fractures were evaluated among which 20 cases were male and 5 female with the mean age 31.84 years. Hypertrophic non-union were 14 and atrophic non union were 11. Upper one third of tib...
