Definitions
- the present invention generally relates to systems and methods for implant trials for orthopedic surgery.
- Various implants, plates, and screws are commonly used to repair fractures and deformities of bones, during orthopedic surgical procedures. It is common in surgical orthopedic procedures for surgeons to select plate sizes using multiple implants available in the re-sterilized sets to determine the correct length of the needed plate or implant, and in some cases width or depth. These implants are placed and removed onto surgical site, e.g. site of the bone fracture or deformity.
- the present method suffers drawbacks, however, since re-sterilized implant sets may not include the needed plate or implant or such plate or implant in the correct size or configuration of screw-holes, guide holes (i.e., k-wire holes), etc.
- the invention can be generally described as a radiopaque template composed of a base substrate material with a radiopaque marker thereon, to create a fiuoroscopically visible template for use in orthopedic surgical procedures.
- a radiopaque component may be imbedded into the template substrate material homogeneously or applied at specific locations on or in the substrate.
- the overall net shape may be the primary feature desired to be observed radiographically; thus radiopaque dyes may be an economical solution and addition to a polymer based material. In other cases, finer details may be desired to be communicated.
- the device may communicate information via a radiopaque component, allowing a surgeon to determine various implant selection criteria, such as overall length, width, and incremental size options.
- implant features such as gaps, holes, or voids in the implant can be visualized using inks, rather than by removing physical material from the trial.
- Clinically relevant information such as surgical techniques (e.g. screw trajectory; screw type; screw insertion order) and patient safety information (e.g. "Do Not Implant”) can also be conveyed using the templates of embodiments of the invention.
- the substrate material may any materials that can be adequately sterilized for use in an operating theater, such as certain polymers and metals.
- the substrate material choice may depend on other functionally relevant characteristics, and the radiopaque compound chosen (receptivity to dye adhesion); known substrate materials with good adhesion include Kapton, Mylar, and Glass, among others.
- the radiopaque component could be composed of a variety of different chemicals depending on the imaging requirements of the information being communicated. In the medical field, barium sulfate, tungsten and bismuth are common radiopaque components.
- the radiopaque component could be formulated yielding different colors, which could be leveraged to communicate similarities and differences between features.
- the idea of the Radiopaque Template can be extended into other Radiopaque Instrument and Implant applications. This could enable clinical benefits and potentially mitigate risks associated with misuse.

- a novel composite trial composed of at least both a metal wireframe and polymer substrate is disclosed. It has been found that the instantly described composite trial implant (also referred to herein simply as a "trial") provides improved performance trials used during orthopedic trauma surgical procedures. Trials according to the present invention are better able to communicate anatomical fit information, provide length and screw locations, are more cost efficient than using actual, sterilized implants, permit improved radiographic visualization, and greater reliability during surgical procedures.
- the invention includes at least wireframe.
- the wireframe 150 may be comprised of a plurality of spine sections 170 and holes 160 that can be used as drill guides, guide wires (e.g. K-wires, or Kirschner wires), or for fixation screws that secure the implant to bone.
- the wireframe 150 contains screw guides 165 that are cannulated with holes 190 for receiving fixation screws.
- the wireframe 150 also includes guide wire guides 160 and guide wire holes 180.
- Exemplary trial implants may include one or both when providing a guide for the implantation of a bone plate.
- a wireframe 250 need not be flat, as it may be used to approximate the topology of the bone onto which a bone plate may ultimately be secured, as illustrated in FIG. 2A. As shown in FIG. 2A,
- the wireframe 250 may include an external wireframe element, such as a circumferential ring
- spine elements 270 may support the placement of screw hole guides 290, each having a screw hole 265 therein.
- Each composite trial implant will include a wireframe, typically made of metal or other rigid (although preferably flexible) material encapsulated within or partially encapsulated within a solid polymer matrix.
- the wireframe 310 may be embedded within a polymer matrix.
- FIG 3 A is view of the polymer matrix showing that the polymer matrix has a size and shape generally similar to an implant or bone plate that will eventually be secured to the bone.
- FIG 3B shows a composite trial implant 300 that has an irregularly shaped top surface 330.
- the wireframe 310 is fully embedded within the polymer matrix and a
- the pharmaceutically active coating 320 is disposed on a bottom surface of the composite trial implant 300.
- the wireframe 310 is radio-opaque to allow the position of the wireframe to be seen in fluoroscopy or x-rays. This feature permits the surgeon to accurately determine the location of the composite trial implant 300 relative to the bone. This may permit the surgeon to insert guide wires using the composite trial implant and then replace the composite trial implant with a permanent bone plate (or other implant) which is then secured to the bone to provide stability to the fractured bone fragments.
- the outer profile of the implant can be communicated along with screw locations. If the wireframe is made of radio-opaque materials, the outer profile of the wireframe and screw locations can be displayed on an x-ray with the bone. Further, wireframe has the ability to allow for screw trajectories to also be communicated through cannulated holes.
- the cannulated holes could as be used for a drill guide. With the objective of minimizing surgical disruption, if the holes are cannulated for drilling the surgeon would be able to trial and drill at the same time.
- the manufacturing method for the wireframes would ideally be 3D printing with additional finishing steps for surface finishing or cannulated holes with more traditional
- the composite trial implant 550 may have a non-linear cross- sectional profile. Screw holes may be provided that provide a trajectory ⁇ for screws inserted therethrough. In FIG. 5B, screw holes that are not perpendicular to the plane of the composite trial implant may be more or less than 90 degrees, such as angles ⁇ and ⁇ .
- the present invention permits a more accurate device for surgeons to determine screw trajectories, and even pre-drill holes in the bone, prior to placement of the permanent implant.
- the Wireframes can be embedded into a polymer matrix/substrate in multiple ways as shown in FIGS 3 A, 3B, 4A, and 4B.
- Such embodiments may include a single layer where the polymer substrate covers the wireframe only on one side.
- a variable composite layer which allows for various surface variations to either aid in trial placement or to match the implant anatomical shape. These surface variations can be very expensive in traditionally machined trials but is cost-efficient in an injection molded, 3D printer, or other manufactured method for the polymer matrix.
- the surface prep composite layer (FIG 4B), allows for various surface coatings (e.g.
- the polymer matrix can be implemented through various manufacturing methods but ideally suited to injection molding or 3D printing; joining of the wireframe can occur through insert/over molding during injection molding or assembly with or without a bonding agent after the wireframe and polymer matrix have been manufactured separately.
- FIGS 5 A and 5B illustrates various methods of hole creation at various angles within the composite trial depending on intended use.
- Cannulated hole used for K-wire insertion is one method of hole creation in the wireframe.
- a threaded hole can be created through direct machining in the wireframe or using an Insert that snaps or assemblies into the wireframe. This would allow for the inserts to be produced on a large scale and reduce cost of manufacturing.
- polymer composite holes 690 can also be created with injection molding of the polymer matrix 660.
- flow holes 690 in the wireframe would allow for the polymer to flow into the cannulation 680 and form a straight or tapered hole 670.
- a screw with a threaded head could be inserted through this polymer hole and the threads on the head of the screw form threads into the polymer. This allows for natural locking due to the thread forming mechanism into the polymer.
- the wire frame can provide various support functions of the thread including increasing strength and endurance while also providing a stop 685 against screw pull through.
- FIGS 7 A and 7B illustrate a screw having a threaded head that can be inserted through the cannulated hole with varying trajectories, permitting the surgeon to create a screw trajectory that best captures bone fragments or provides the greatest stability to the bone being fixed with a plate or implant.
- Implants in most systems, especially trauma system,s contain implants that share common features with a few points of variations; primarily the variation is length (shaft holes) but also includes head width, hook depth and extension features.
- the concept of the composite trial is support the trialing of an implant system with a limited number of composite trials.
- the example shown is an implant family that varies in length from 3 hole to "n" hole.
- the composite trial allows for connector features to be designed into the polymer matrix so that you would only need two trials to support the entire "n" hole family of implants; there are multiple variations of this concept that could reduce the required composite trials to more or less than 2 trials.
- the concept is that the composite trial "articular head” would allow for the anatomical fit within the anatomical region while the "length connector” allows for shaft length measurement. This connector concept is shown additionally in FIG. 9.
- K-wire holes that allow for preliminary fixation during the procedure.
- K-wire holes also may be placed in the "articular head" of the composite trial to allow for "pinning” or secure the location of the desire implant one the trial has been placed at the desired position.
- the trial can be removed and the actual implant selected can be placed into the approximate location using the K-wires. This would significantly reduce the surgical implant of trialing during a Trauma procedure. It also could allow for more efficient surgical procedure and reduce the impact of using actual implant to trial during the surgical procedure.
- FIGS 10A-10E illustrate various embodiments for composite trial implants. [0051] Together the composite trial meets the need for trials/sizing guides in orthopedic trauma procedures that are able to communicate anatomical fit information as well length and screw locations while being cost efficient, allow for radiographic visualization and minimize disruption to surgical procedure.
- the idea of the composite trial can be extended into a composite implant comprised of a biocompatible and implant grade polymer matrix and wireframe. This could reduce the cost of manufacturing implants while maintaining the clinical strength requirements by optimizing the design characteristic of the composite implant.
- various surface coatings could more easily be considered given the carbon chain of the polymer; this could allow for various combination drugs between pharmaceutical or biologies depending on the material characteristics and selection.
- the invention can be generally described as a radiopaque template composed of a base substrate material with a radiopaque marker thereon, to create a fluoroscopically visible template, or template with fluoroscopically visible indicia, for use in orthopedic surgical procedures.
- a radiopaque component may be imbedded into the template substrate material homogeneously or applied at specific locations on or in the substrate.
- the overall net shape may be the primary feature desired to be observed radiographically; thus radiopaque dyes may be an economical solution and addition to a polymer based material. In other cases, finer details may be desired to be communicated.
- the device may communicate information via a radiopaque component, allowing a surgeon to determine various implant selection criteria, such as overall length, width, and incremental size options.
- implant features such as gaps, holes, or voids in the implant can be visualized using inks, rather than by removing physical material from the trial.
- Clinically relevant information such as surgical techniques (e.g. screw trajectory; screw type; screw insertion order) and patient safety information (e.g. "Do Not Implant”) can also be conveyed using the templates of embodiments of the invention.
- the substrate material may any materials that can be adequately sterilized for use in an operating theater, such as certain polymers and metals.
- the substrate material choice may depend on other functionally relevant characteristics, and the radiopaque compound chosen (receptivity to dye adhesion); known substrate materials with good adhesion include Kapton, Mylar, glasses and ceramics.
- the radiopaque component could be composed of a variety of different chemicals depending on the imaging requirements of the information being communicated. In the medical field, barium sulfate, tungsten and bismuth are common radiopaque components.
- the radiopaque component could be formulated yielding different colors, which could be leveraged to communicate similarities and differences between features.
- the idea of the Radiopaque Template can be extended into other Radiopaque Instrument and Implant applications. This could enable clinical benefits and potentially mitigate risks associated with misuse.
- a template size guide such as those illustrated in Figs. 12-16, can assist the surgeon in implant selection. Desired features of the template include communication of length and width information; implant feature locations (e.g. screw holes, k-wire holes).
- implant feature locations e.g. screw holes, k-wire holes.
- a desired attribute is radiographic visualization, which enables the template to be inserted subcutaneously to prevent unnecessary incisions and still communicate implant information.
- templates are implant sized instruments, which enable the communication of length and width information, under the naked eye.
- the instruments are commonly made out of a metal material which allows for net radiographic visualization but do not allow for adequate visualization of implant feature locations (e.g. screw locations) using imaging technology.
- Prior art devices in which instruments attempt to address the need for radiopaque visualization by having holes or voids in the template to communicate corresponding implant feature locations, pose risks of the instrument accidentally being implanted, and only communicate important information to the surgeon by the inability for various holes and voids to appear in a fluoroscopic image. In other prior art devices, where material is not removed, the information is communicated via markings (e.g. etches) which are visual under the naked eye, but not radiographically. Additionally, most current templates are not economical solutions due to their metal base material. Therefore a template solution which enables the base material to be a less costly polymer, is advantageous.
- Devices such as those shown in Figs. 12-16 overcome the problems of the prior art by providing inexpensive, substrate-based templates that cannot be accidentally implanted into a patients.
- the novel device of the present invention comprises substrates with radio-opaque markings. These devices appear similar, or even identical, to actual bone plates when viewed radiographically, but plainly appear as trial templates to the surgeon when viewed directly.
- the template trials may also appear similar to an actual bone plate or implant, when viewed
- radiographically but may also show indicia in the radiographic image.
