He has pioneered a novel foot and ankle reconstruction surgery, using PMMA (Poly Methyl Methacrylate), also called Bone Cement, as foot bone replacement prosthesis for severely destroyed foot and ankle bones. (theseoultimes.com)
About 30% of these people experienced loosening and needed surgery to fix or replace their prostheses an average of 34 months after surgery. (healthline.com)
Tricalcium phosphate (TCP) has been used as a ceramic bone substitute material in the orthopedic field and in craniofacial surgery. (allenpress.com)
In general, surgery is the main treatment for primary bone cancer. (uchealth.org)
In hip resurfacing surgery, the amount of bone that is removed is lesser than that in a hip replacement surgery. (health-tourism.com)
If the hip resurfacing parts are required to be replaced eventually, there is an adequate amount of bone that is left to conduct a hip replacement surgery. (health-tourism.com)

Noncemented prostheses have a roughened surface, and eventually the surrounding bone will grow into the rough metal surface to provide additional stability. (shouldersurgeon.com)
There is no adverse effect on prosthesis stability due to the scanty cement shrinkage. (alliedmarketresearch.com)

Prostheses for motion preservation. (maxxspine.de)
Impaction bone grafting (IBG) as a valuable bone preservation technique could effectively address this problem. (bvsalud.org)

The composition of these types of cement is mostly based on calcium phosphate and more recently magnesium phosphate. (wikipedia.org)
As mentioned by Chow, 16 the use of calcium phosphates as a stimulus for bone formation appeared in the literature as early as 1920. (allenpress.com)

Today several million procedures of this type are conducted every year all over the world and more than half of them routinely use bone cements - and the proportion is increasing. (wikipedia.org)

Unlike the prostheses used in total hip replacement, which are made to replace the femoral head, resurfacing prosthesis designs allow the head to be preserved and reshaped. (lifealert.com)
The cap is then fitted into the femoral head and fixed in place with a small peg that is attached into the bone. (health-tourism.com)

How vigorously you use your elbow joint after the procedure has a major impact on the risk that the prosthesis will loosen. (healthline.com)

Possible serious consequences caused by cement leakage are an embolism or a compressing of the spinal cord. (allesporoes.de)

Both these conditions result in the destruction or excision of foot bones which leads to deformed feet with altered biomechanics and the appearance of new pressure points in regions of the foot unaccustomed to bearing such forces. (theseoultimes.com)

Hip replacements may be cemented or uncemented. (lifealert.com)
Multiple different materials throughout history have been tested as replacements for bone. (medscape.com)

7 , 8 Several authors 9 - 15 have tried various techniques, such as the use of barrier membranes, autogenous bone, and bone substitutes with or without platelet-rich plasma, to manage this problem. (allenpress.com)
Cellulose (dialysis membranes and cement for hip prostheses). (presi.com)

Adhesive prosthesis. (edicionesedra.com)

They are generally cured photochemically using UV radiation in contrast to bone cements. (wikipedia.org)
He observed that this highly aggressive bone cancer was remarkably sensitive to radiation therapy. (sarcomahelp.org)

A prosthesis is designed to duplicate the mechanical properties of the joint being replaced. (carondelet.org)

The bone cement fills the free space between the prosthesis and the bone and plays the important role of an elastic zone. (wikipedia.org)
