Abstract:

BACKGROUND: Osteoporosis caused by the vertebral fractures in orthopedic clinical disease is very common; due to pain, kyphosis affects the quality of life of older persons. In recent years using balloon kyphoplasty (PKP) treatment of the disease to obtain good clinical, but its use of traditional bone cement filler has many shortcomings, and injectable calcium sulfate is a biocompatible, safe and effective bone substitute material, as the method of filling enhanced to make up for the lack of bone cement.
OBJECTIVE: By analyzing and summarizing bone cement and injectable calcium sulfate in the kyphoplasty in applied research since 1975, to look for ideal filling materials for kyphoplasty.
METHODS: By using "osteoporosis, percutaueous kyphoplasty (PKP), calcium sulfate cement (CSC), polymethylmethacrylate (PMMA)" as keywords, we retrieved articles published 1975-01/2009-12 included in Wanfang database and PubMed database. Irrelevant and the repetitive contents were excluded. Twenty-five documents retained for further analysis.
RESULTS AND CONCLUSION: Ideal effective implants may be injection shall be of good, can precisely infuse fracture sites, and may reduce the injection pressure; they can rapidly be solidified, have enough mechanical strength, stable, immediately recover vertebral body load capacity; Solidification low temperature, can reduce heat damage to nearby tissue; A good imaging capabilities, can develop during the operation, which precisely control the location and depth of the filler; can be slowly biodegradable; Material origin is widespread, and cheaper prices. At present there is no a filling materials can completely have the above advantages. Therefore, the research to develop a kind of ideal filling materials for clinical use is an important task in the future.
