title: [Comparative study of three different hip function evaluation systems].
abstract: Harris's, Charnley's and Beijing's numerical rating systems were used to evaluate the functional results of 42 cases of bipolar type artificial femoral head replacement. The results of assessment of the three methods were compared statistically and proved that the results are comparable. Before the overall evaluation, the patients should be divided into three groups (according to Charnley's method) on the basis of their original capacity of locomotion. The score results of the three groups should not be mixed up. The calculation method of total score of Beijing system may need certain modification. The advantages and disadvantages of the three systems, the significance of capacity assessment of daily activity and radiological evaluation are discussed on the basis of the results of analysis.
