The present inventive subject matter describes a device and system for positioning, adjusting, and stretching a patient's extremity for surgical procedures where alignment is critical and minute adjustments may be required repeatedly. The device helps in maintaining the patient's extremity stationary, once the physician has selected the precise position for the elected procedure. The device uses using a combination of an articulating and a rotating frame, support plates and support rings that are attached to the extremity surgical positioning system. The system acts as a limb splint that is firmly attached to the surgical table. The support plates are attached to the patient via a series of adjustable straps preventing the extremity from moving independently of the support plate. A locking rack and gear configuration has adjustable locking pivot points that are positioned along and within the outer/inner proximal tube and outer/inner distal tube that lengthens or rotates various portions of the extremity.
