OBJECTIVE We have developed a standardized technique for intra-articular injection of the hip joint with the purpose of extending routine intra-articular injection of hyaluronans and steroids to the hip, as commonly used in the knee. The purpose of this study was to examine the safety of this technique in an extended series of patients. METHODS A 7 MHz(More)

This paper presents a two-stage neural system to determine the contact points between a three-® ngered gripper and an object of arbitrary shape. In the ® rst stage, a CCD camera captures the image of the object and such an image is transformed into a two-dimensional outline through a nearest neighbour algorithm. In the second phase, two neural networks,(More)
