title: [Study on the Distribution of Constitutions of Chinese Medicine in Patients with Osteonecrosis of Femoral Head].
abstract: OBJECTIVE
  To observe the distribution of constitution types of Chinese medicine (CM) in patients with osteonecrosis of femoral head (ONFH).
  
  
  METHODS
  Totally 130 ONFH patients were recruited. Constitution types of CM were identified in all patients. Distribution features of constitution types of CM in ONFH patients were observed. The differences of distribution in gender, age, single or bilateral hips, course of disease, staging, cause, and region were also analyzed.
  
  
  RESULTS
  Seventy patients were of complicated constitutions, while 60 patients were of single constitution. Among the 60 single constitution cases, yang-deficiency constitution [18 (13.9%)], damp-heat constitution [10 (7.7%)], blood-stasis constitution [7 (5.4%)], and qi-deficiency constitution [7 (5.4%)] were mainly distributed. Of the complicated constitutions, yang-deficiency dominated constitution occupied the top ratio [30 (23.1%)], followed by blood-stasis dominated constitution [15 (11.5%)], damp-heat dominated constitution [9 (6.9%)]. By putting them together, yang-deficiency constitution occupied the top constitution of CM [48 (36.9%)], followed by blood-stasis constitution [ 22 (16.9%)] and damp-heat constitution [19 (14.6%)]. The aforesaid three constitutions accounted for 68.5% of the total. There were no statistical distribution differences in gender, age, single or bilateral hips, course of disease, staging, or cause.
  
  
  CONCLUSIONS
  Yang-deficiency constitution, damp-heat constitution, and blood-stasis constitution were liable constitutions of CM in ONFH patients.
