Total hip and total knee replacement: first of two parts

Article Abstract:

Total hip replacement is performed to increase the mobility of people who suffer from severe arthritis of the hip. The head of the femur (the top of bone of the upper leg) is replaced by a small metal sphere attached to a stem, which is inserted into the femur. It is set in place in the acetabulum, the 'socket' of the hip joint, after that structure is enlarged and lined with a high-density polyethylene. The components are attached to the skeleton either by cement or by ingrowth of bone into their porous surfaces. A review of several aspects of total hip replacement is provided. Included are: indications for the procedure; rehabilitation afterwards; complications; results; cemented compared with cementless total hip replacements; and the future of the procedure. Overall, after replacement, hip function is good, but not normal, with the best results among older patients. Ordinary activities are possible, but not vigorous ones. Pain relief is dramatic and complications are relatively infrequent. However, new problems arise when the plastic remains in the body for many years, as it more commonly does in the cases of younger patients.

Tissue engineering for reconstruction of the thumb

Article Abstract:

The ultimate goal of tissue engineering should be the creation of an organ or body part that is accepted by the body and functions normally. A man whose injured thumb was reconstructed using his own bone cells and a piece of coral could not move the thumb two years later.

Replacement of an avulsed phalanx with tissue-engineered bone

Article Abstract:

Doctors report the case of a man whose injured thumb was replaced with a piece of natural coral that was injected with bone cells taken from his arm. A biopsy of the thumb 10 months later showed new bone growth integrated with the coral scaffold.
