Abstract
A drill guide for controlling the first metacarpal while maintaining the proper trajectory of the drill. The drill guide includes a guide rail having an elongated shaft and a guide body with an aperture extending therethrough. The aperture is configured to receive the elongated shaft of the guide rail. The drill guide also includes a distal ring connected to the elongated shaft. A spike and a hook are both attached to the distal ring and extend therefrom. The hook and the spike extend from opposing positions along the distal ring. A trigger end of the guide body has a trigger that, when actuated, allows the guide body to slide along the guide rail in a proximal direction. A drilling end of the guide body has a rotatable drill bullet extending distally therefrom. The drill bullet includes a pair of arms lined with teeth for engaging the first metacarpal.
