title: [Treatment of fracture involved articular surface with absorbable screws and rods].
abstract: OBJECTIVE
  To investigate the treatment results of fracture involved articular surface with absorbable screws and rods.
  
  
  METHODS
  From October 1995 to May 2002, 32 patients with fracture involved articular surface were treated with absorbable screws and rods with the materials of SR-PGA and SR-PLLA. Bone traction or plaster external fixation were carried out postoperatively.
  
  
  RESULTS
  The followed-up period varied from 3 months to 78 months, with an average of 18.5 months. According to the articular function evaluation criteria, the results were excellent in 24 patients, good in 6 patients and fair in 2 patients. The excellent and good rate was 93.7%. The fractures healed, without dislocation, infection and local effusion.
  
  
  CONCLUSIONS
  Internal fixation of absorbable screws and rods is a perfect procedure for treating fracture involved articular surface, which avoided the pain of taking out internal fixation materials of the second operation.
