title: ARTHROSCOPIC TREATMENT OF SYNOVIAL OSTEOCHONDROMATOSIS OF THE HIP.
abstract: OBJECTIVE
  The objective of this study is to show the results achieved in the treatment of hip osteochondromatosis by arthroscopy.
  
  
  METHODS
  Six patients submitted to hip arthroscopy for synovial osteochondromatosis have been assessed for pre- and postoperative function and pain. The time of preoperative complaint ranged from nine to 48 months, in an average of 28.2 months and the follow-up ranged from eight to 25 months (mean: 17.1 months). Mean age was 45.1 years, with four female patients (66.6%) and the right side affected in five cases (83.3%).
  
  
  RESULTS
  Concerning the results according to Byrd-modified Harris' criteria, the mean score evolved from 54.1 to 90.4, and the mean score on the face expressions scale for pain assessment ranged from 1.7 to 5.1.
  
  
  CONCLUSIONS
  arthroscopy is a good alternative for hip osteochondromatosis treatment, although longer follow-up times are required to strictly stating this. The results found so far are encouraging, constituting a littleinvasive procedure allowing good recovery.
