Medical implant device

A joint implant device, comprising:

• a body having a first end to couple with a sphere and a second end to couple with a stem;
• a sensor coupled with the body, the sensor to detect a physical metric proximate the first end of the body;
• the body comprising:
• a guide surface;
• a first support coupled with the guide surface;
• a worm gear rotatably coupled with the first support, the worm gear to rotate with the first support in a stationary position relative to a rotation direction;
• a second support movably coupled with the first support, the second support having a worm wheel to engage with the worm gear;
• a third support movably coupled with the second support, the third support including a projection that extends in an axial direction along an outer surface of the third support;
• a fourth support including a slot that extends in the axial direction along an inner surface of the fourth support, the slot configured to receive the projection of the third support to rotatably fix the fourth support to the third support;
• and
• the third support to move in the axial direction up to 5 centimeters relative to the first support and the fourth support with activation of the worm wheel to elongate the body.
