In order to get the precise blood pressure and pulse number in the cuffless status, the wrist wearable pulsimeter with a portable and small size apparatus using by Hall device is developed. The regression analysis of the pulse wave measured by the testing product of pulsimeter is conducted two equations of the blood pressure algorithm. The estimated values of blood pressure obtained by the cuffless pulsimeter during 5 s are compared with the practical values measured by electronic or mercury liquid blood pressure meters. The standard deviation of the estimated value and the practical value for the high blood pressure and the low blood pressure were 12.1 and 5.9, respectively, which have the neighborhood values of BP International Standard. The detail analysis of a pulse wave measured by cuffless wrist wearable detecting the changes of the magnetic field can be used to develop a new diagnostic algorithm of blood pressure applying for oriental medical apparatus like as the wrist wearable pulsimeter.

Purposes : To evaluate the result and technique of arthroscopic reduction with probe for Intraarticular fracture of the tibial condyles. Materials and Methods : From October 1998 through January 2000, 15 patients were treated for Intraarticular tibial condylar fracture. Average follow up were 22 months, with a range of 13 to 46 months According to Schatzker classification,3 cases were classified as pure cleavage(type Ⅰ),8 cases of cleavage with depression(type Ⅱ) and 4 cases of pure central depression(type Ⅲ) For accurate reduction, we used probe to elevate the depressed fracture fragment. Results : The results were obtained from 15 patients who had been Intraarticular tibial condylar fracture and Judged by Porter's criteria Eleven cases revealed more than good results. Conclusion : Intraarticular reduction method for tibial condyle fractures had several advantage such as providing accurate reduction, preventing cartilage perforation and easy to perform.
