abstract a length-adjustable im nail system includes telescoping im nail with proximal and distal bodies. an inner magnet within the proximal body is connected to a threaded rod which, in turn, is connected to the distal body. the threaded rod passes through a threaded block which is connected to the proximal body. the position of the distal end of the threaded rod is fixed with respect to the distal body, but may rotate freely within this fixed position. an actuator is also disclosed that includes a pair of rotating magnets disposed in an angular relationship with each other and the axis of the nail and the patient's limb. rotation of these outer magnets in the same direction results in rotation of the inner magnet and threaded rod and axial telescoping movement of the threaded block and proximal body with respect to the distal body. Patent abstract: "telescopic nail and actuation mechanism". This is an im adjustable length nail system including a telescopic im nail with proximal and distal bodies. An internal magnet in the proximal body is connected to a threaded rod which, in turn, is connected to the distal body. The threaded rod passes through a threaded block that is connected to the proximal body. The position of the distal end of the threaded rod is fixed relative to the distal body, but can rotate freely in that fixed position. An actuator is also presented which includes a pair of rotating magnets arranged in an angular relationship to each other and the geometric axis of the nail im and the patient's limb. rotation of these outer magnets in the same direction results in the rotation of the inner magnet and the threaded rod and a telescopic axial movement of the threaded block and proximal body relative to the distal body. 19757931v1 19757931v1abstract a length-adjustable im nail system includes a telescoping im nail with proximal and distal bodies. an inner magnet within the proximal body is connected to a threaded rod which, in turn, is connected to the
