title: [3-D adjustable design of humeral prosthesis].
abstract: OBJECTIVE
  To study the shoulder anatomy characteristics of the Chinese people and to design a new kind of humeral prosthesis, which could realize the adjustment in three-dimensional space and be adjusted repeatedly, based on Chinese humeral anatomy characteristics.
  
  
  METHODS
  A double-gear structure as a rotating part was adopted to design the structure of this new kind humeral prosthesis.
  
  
  RESULTS
  The humeral prosthesis could satisfy both the needs of Chinese individual shoulder characteristics and the Westerners' demands.
  
  
  CONCLUSIONS
  A novel concept of shoulder prosthesis design with a strong application value in design and development of the new prosthesis is proposed.
