BACKGROUND There is no national joint replacement registry in the country of Asia and reports of national outcomes of joint replacement in Asia as yet. Therefore, this study was then to report a national data of the number of hip replacements, incidence rate, demographic characteristics of hip replacement patients, and short-time survival rate after hip replacement of Han Chinese in Taiwan. M...

BACKGROUND The treatment of malignant bone tumors in skeletally immature patients is difficult because the required surgery removes the growth plate of one extremity. To date, few techniques for limb salvage have been successful due to complications involving limb expansion and limb-length discrepancy. Newer technology is now available for prosthetic replacements for modular expansion. METHOD...

INTRODUCTION Total humeral replacement is used to reconstruct the upper limb after tumour resection, while in cases of complex revisions for non-oncological reasons, using tumour prosthesis implants will lead to an otherwise avoidable further bone resection and violation of the surrounding tissues. This report describes a design evolution in three non-oncological cases, where a total humeral re...

Hip resurfacing is a bone-conserving procedure with respect to proximal femoral resection, but there is debate in the literature as to whether the same holds true for the acetabulum. We have investigated whether the Birmingham hip resurfacing conserves acetabular bone. Between 1998 and 2005, 500 Birmingham hip resurfacings were performed by two surgeons. Between 1996 and 2005 they undertook 700...

Joint replacement is the most effective healthcare measure in improving patient quality-of-life outcomes. More than 46000 hip and knee replacements were performed in Australia between July 2000 and July 2001. The need for joint replacements will increase as the population ages. More than 90% of hip and/or knee replacements survive for 10-15 years. Prosthesis selection needs to be tailored to ea...

Alveolar bone augmentation in vertical dimension remains the holy grail of periodontal tissue engineering. Successful dental implant placement for restoration of edentulous sites depends on the quality and quantity of alveolar bone available in all spatial dimensions. There are several surgical techniques used alone or in combination with natural or synthetic graft materials to achieve vertical...

In order to combat the low regenerative capabilities of ligaments full ‘bone to bone’ replacements are required, which will integrate with bone while providing a smooth transition to the replacement soft tissue (tissues surrounding organs in the body, not being bone). This study investigated the use of 3D powder printing technology to form calcium phosphate brackets, previously used for forming...
