title: [PROGRESS AND CLINICAL APPLICATION OF ALLOGRAFT BONE SPACER IN CERVICAL AND LUMBAR INTERBODY FUSION].
abstract: OBJECTIVE
  To review the research progress and clinical application of allograft bone spacer in cervical and lumbar interbody fusion.
  
  
  METHODS
  Literature about allograft bone spacer in cervical and lumbar degenerative disease was reviewed and analyzed, including the advantages and disadvantages of allograft material, fusion rate, effectiveness, and complications.
  
  
  RESULTS
  Fusion rate and effectiveness of allograft bone spacers were similar to those of autograft and polyetheretherketone spacers, and they were recommended by many orthopedists. However, indications, long-term effectiveness, and complications were not clear.
  
  
  CONCLUSIONS
  Further study on allograft bone spacer in cervical and lumbar interbody fusion should be focused on optimal indications and long-term effectiveness.
