The shape memory alloys exhibit a number of remarkable properties, which open new possibilities in engineering and more specifically in biomedical engineering. The most important alloy used in biomedical applications is NiTi. This alloy combines the characteristics of the shape memory effect and superelasticity with excellent corrosion resistance, wear characteristics, mechanical properties and...

INTRODUCTION The objective of this study was to assess three-dimensional bone geometry and density at the epiphysis and shaft of the third meta-carpal bone of rheumatoid arthritis (RA) patients in comparison to healthy controls with the novel method of peripheral quantitative computed tomography (pQCT). METHODS PQCT scans were performed in 50 female RA patients and 100 healthy female controls...

While free flaps have been widely used for reconstruction of pretibial defects, the extended operation times are known to be a major drawback. This report presents case successful lower leg large defect with bone-anchored advancement flap and split-thickness skin graft. A 59-year-old female patient underwent wide excision sarcoma on area. The measured 14×6 cm 10×2 exposure tibia in medial aspec...

The monitoring of fracture or osteotomy healing is vital for orthopedists to help advise, if necessary, secondary treatments improving outcomes and minimizing patient suffering. It has been decades since stiffness identified as one main parameter quantify qualify the outcome a regenerated callus. Still, radiographic imaging remains current standard diagnostic technique orthopedists. Hence, with...

Autologous bone grafts for alveolar ridge augmentation are the gold standard for restoring atrophic residual ridges in preprosthetic surgery. Many indications, donor sites, and techniques have been reported. The purpose of this article is to review the anatomy, surgical technique, and potential complications associated with proximal tibia bone harvest. A consecutive series of 44 patients who un...

OBJECTIVE Treatment of congenital pseudarthrosis of the tibia (CPT) remains a challenge. The autogenic iliac bone graft is important consistent of treatment for CPT. The purpose of this study was to investigate the role of wrapping autogenic iliac bone graft in improvement of the curing opportunities of CPT. METHODS We combined Ilizarov fixator with intramedullary rodding of the tibia and wra...

Bone graft is essential in various orthopaedic procedures. Among the many donor sites for harvesting autologous bone graft, the iliac crest has been the most commonly used. However, for foot and ankle procedures the proximal tibia has gained popularity as an alternative donor site due to its anatomic proximity to the primary surgical site. In this article we evaluated the possible complications...

This article describes a patient in whom total knee arthroplasty was performed for neuropathic joint disease secondary to diabetes mellitus after severe bone destruction eroded the tibial tuberosity. At initial examination, radiographs of the knee showed bone destruction in the medial and anterior regions of the tibia, and fine bone fragments were seen in the joint. Conservative therapy was per...

INTRODUCTION Tibia fracture caused by high velocity missiles is mostly comminuted and followed by bone defect which makes their healing process extremely difficult and prone to numerous complications. CASE OUTLINE A 34-year-old male was wounded at close range by a semi-automatic gun missile. He was wounded in the distal area of the left tibia and suffered a massive defect of the bone and soft...
