Abstract

An orthopaedic element has an information storage portion. A transmitter portion and an internal power source portion may be associated with the body of the orthopaedic element. Information, such as data related to the orthopaedic element, patient or caregiver can be stored in the information storage portion. The transmitter portion is coupled to the information storage portion and the internal power source portion. The stored information is selectively transmitted to an external receiver and data interpretation device.

Claims

1. An orthopaedic assembly comprising:

an orthopaedic element and a carrier element mechanically connected to the orthopaedic element,

the orthopaedic element having two ends, a body extending between the two ends, a length and an axis, the orthopaedic element comprising at least one of the following;

an orthopaedic prosthetic component;

an orthopaedic trauma product;

an orthopaedic instrument; and

an orthopaedic trial;

the carrier element having a male portion and an integral body, the body including an information storage portion, the information storage portion comprising a radio-frequency identification tag;

the carrier element being free from any drive mechanism;

wherein one of the ends of the orthopaedic element has an opening that receives the male portion of the carrier element to connect the carrier element to the orthopaedic element;

wherein the opening in the orthopaedic element and the male portion of the carrier element are sized and shaped to temporarily fix the position of the male portion of the carrier element relative to the orthopaedic element;

wherein at least a portion of the body of the carrier element is spaced axially from the body of the orthopaedic element; and

wherein the length of the body of the carrier element is less than the length of the body of the orthopaedic element.

2. The orthopaedic assembly of claim 1 wherein the carrier element is detachable from the remainder of the body.

3. The orthopaedic assembly of claim 1 wherein the carrier element is connected to the orthopaedic element through a threaded connection.

4. The orthopaedic assembly of claim 1 wherein the male portion and body of the carrier element are integral.

5. An orthopaedic assembly comprising a bone screw and a detachable carrier element, the bone screw having a threaded body and a head with an opening sized and shaped to be capable of receiving a portion of a surgical instrument for driving the screw into the patient'"'"'s bone, the detachable carrier element including a body portion and an integral male portion received within the opening at the end of the bone screw to mechanically connect the detachable carrier element to the bone screw, the integral male portion of the carrier element and the opening at the end of the bone screw being sized and shaped so that the position of the carrier element relative to the bone screw is temporarily fixed, the body portion of the detachable carrier element including an information storage portion, the information storage portion comprising a radio-frequency identification tag, the detachable carrier element being free from any drive mechanism.
