Bone defects, which can be caused by factors such as trauma, tumor, or osteomyelitis, are clinically common. They lessen the weight a bone is able to bear and cause severe pain patient. Although transplantation gold standard for treating it not suitable all patients due its poor availability, risk of spreading disease, possibility requiring secondary surgery. cement filler defects fill any shap...

Despite extensive experience with prosthetic replacement for the reconstruction of limbs following juxta-articular resection of tumours, there are few reports of prosthetic replacement of the distal radius. We present two cases of massive bone defects of the distal radius in which alumina ceramic prosthetic replacements were used. We evaluated the patients more than ten years after the procedur...

We report the use of a fillet of upper arm pedicled flap, which has not been previously reported in the literature. The fillet of upper arm flap follows the principle of "spare parts" surgery, and can provide vascularized soft tissue coverage for defects of the shoulder and the chest wall when the upper extremity cannot otherwise be salvaged, such as in cases of radical tumor excision. The fill...

The objective of the present study was to investigate our novel methods for the repair of massive cartilage defects by joint distraction and motion using an external fixator. In this study, we used a rabbit model of massive articular cartilage defect in order to evaluate the effectiveness of using joint distraction and motion with a ring-type external fixator. This external fixator has a hinged...

the purpose of this study was to evaluate the efficacy of two types of bone substitutes, bio-oss and nuoss, for repair of bone defects.this study was performed on the calvaria of 14 new zealand rabbits. the 6mm critical size defect (csd) models of bone regeneration were used. three csds were created in each surgical site. the first defect was filled with nuoss, the second one with bio-oss and t...

The problem of reverse shoulder arthroplasty with various deformities the glenoid is relevant for modern traumatology and orthopedics. In addition to defects, methods solving which can be eccentric reaming by milling cutters, bone autoplasty, augmentation, use individual implants, orthopedic traumatologists have deal a decrease in mineral density tissue scapula. aim this study demonstrate possi...
