摘要

人工造成家兔桡骨缺损后植入同种异体的微孔和无微孔脱钙骨基质（ＰＤＢＭ、ＮＰＤＢＭ）及微孔和无微孔表面脱钙骨（ＰＳＤＢ、ＮＰＳＤＢ）等四种骨组织，手术后２、４、８、１２周进行９９ｍＴｃ－ＭＤＰ骨显像，并与Ｘ线平片及组织学变化相比较。结果表明，微孔制备有利于植入骨的新骨形成，加速植入材料的新骨替代；ＳＤＢ具有与ＤＢＭ相似的诱导成骨作用；核素骨显像对早期判断异体移植骨的成活情况是一种有效而首选的方法。

Abstract

Four different kinds of bone graft were implanted in right or left defective radius of rabbits:perforated decalcified bone matrix（PDBM）

non-perforated decalcified bone matrix（NPDBM）

perforated stirface-decalcified bone（PSDB）and non-perforated surface-decalcified bone（NPSDB）.After implantation

the rabbits were killed at 2

8 and 12 weeks respectively

and studied by radionuclide bone imaging

then compared by radiological and histological examinations.The results showed that perforations on bone may enhance the incorporation between graff and host bone and the new bone formation. SDB has the same osteogenesis induction effect as DBM.It was concluded that 99mTc-MDP bone imaging was an effective and first chosen method for the early diagnosis of viability in bone allograft.
