Abstract

According to the General Administration of Quality Supervision, Inspection, and Quarantine: National Standards Committee Proclamation (2005, No. 146), GB 16396-1996 “Clinical Diagnosis and Classification of Endemic Osteofluorosis” shall be repealed as of the date of implementation of these Criteria.

These Criteria combine GB 16396-1996 “Clinical Diagnosis and Classification of Endemic Osteofluorosis” and WS 192-1999 “X-ray Diagnosis of Osteofluorosis” into a single standard.   WS 192-1999 “X-ray Diagnosis of Osteofluorosis” shall be repealed as of the date of implementation of these Criteria.

The major changes included in these Criteria relative to GB 16396-1996 “Clinical Diagnosis and Classification of Endemic Osteofluorosis” and WS 192-1999 “X-ray Diagnosis of Osteofluorosis” are as follows:

  • The name is changed to “Diagnostic Criteria for Endemic Osteofluorosis”
  • Joint pain and body motion dysfunction which affect patients ability to work and live normally have been included as diagnostic and classificatory criteria
  • Clinical manifestations (symptoms, signs) of osteofluorosis are listed
  • X-ray manifestations of osteofluorosis are also listed, including diagnostic and classificatory criteria
  • An emphasis is placed on the fact that clinical symptoms, clinical signs as well as bone and joint x-ray changes may all be used for diagnosis and classification. When there is a conflict between clinical diagnosis or classification and x-ray diagnosis or classification, the x-ray results shall be taken as the standard
  • Simplified the 3a, 3b, 3c, and 3d subclassification of the level 3 classification in GB 16396-1996 “Clinical Diagnosis and Classification of Endemic Osteofluorosis”; all are now classified as “severe”
  • Changed “increase in bone mass” to osteosclerosis, changed “decrease in bone mass” to osteoporosis or osteomalacia
  • Added differential diagnosis material

These Criteria includes informative annexes A and B.

These Criteria have been proposed by the Endemic Disease Standards Expert Committee of the Ministry of Health.

These Criteria have been approved by the Ministry of Health of the People’s Republic of China.
