Abstract
A flexible plastic, resin or polymer material forming a trial plate for use is surgery of bones including spine and extremities. The trial plate having at least one radioopaque region and which may have one radiolucent region. In some instances a main body includes one or more arms formed of subparts. Between the main body and subparts and between the subparts are rangible regions such a ribs or unbroken edges surrounding windows configured as predetermined break points to disassociate portions of an arm from the whole.
Claims20
An adjustable implant template comprising:
- a flexible trial plate (400) having a main body (410) and configured with two arms (415 and 415′) extending from the main body;
- each extended arm further comprising;
- at least one subarm extending from each arm (420);
- one or more slots (430) interposed between subarms and partially separating subarms;
- and,
- wherein removal of a subarm from at least one end of the an arm reduces the length of the trial plate.
An adjustable:
- implant template comprising:
- a flexible:
- trial plate (400) having a main body (410) and configured with two arms (415 and 415′) extending from the main body;
- each extended arm further comprising;
- at least one removable subarm (420);
- one or unbroken edges configured to form a slot or gap between adjacent subarms;
- a break zone (543) formed on at least a portion of the unbroken edge;
- and, a guide edge (431) of the subarms is visible through the gap or slot;
A method of dynamically adjusting an implant template, the method comprising:
- comparing a trial plate (400) with a selected implant;
- and,
- disassociating at least one subarms from an extended arms of said trial plate by breaking or cutting a an unbroken edge or rib connecting the at least one subarms to the trial plate;
- and,
- whereby the length of the flexible trial plate (400) is reduced.
An implant template comprising:
- a flexible trial plate having a main body and configured with at least one arm extending from the main body:
- the at least one arm further comprising;
- at least one subarm;
- and,
- one or more slots or windows interposed between the at least one subarm and at least one frangible rib partially separating the at least one subarm from the at least one arm.
