BACKGROUND

Stabilizing bones and guiding growth of bones with surgical implants such as metal plates has been the basis of orthopedic surgery for decades. Guiding growth by harnessing the ability of growing bone to undergo plastic deformation is one of the oldest orthopedic principles. Correction of deformity remains a major part of the workload for pediatric orthopedic surgeons. Recently, along with developments in limb reconstruction and computer-directed frame correction, there has been renewed interest in surgical methods of physeal manipulation to guide growth of the bone. Manipulating natural bone growth to correct a deformity is appealing, as it allows gradual correction by minimally invasive means. Growth modulation surgery is one of the most common types of surgery in pediatric orthopedics.

Typically, in order to accomplish this procedure, an orthopedic surgeon (or other medical practitioner) exposes the bone and must retract surrounding tissues to provide the surgeon with necessary and continuous access to the bone. The surgeon then precisely aligns an implant over a specific region of the bone to affix a metal plate to the bone with special screws. This process can take a substantial amount of time and can often cause damage to the surrounding tissues, which can significantly impact the post-operative recovery for the patient.

Additionally, numerous radiographic images are normally taken during various stages of the operation to ensure the metal plate is properly positioned on the bone. The number of images that are typically obtained—some with the surgeon's hands in the field—can be in the dozens, potentially resulting in relatively high radiation to the patient, the surgeon and other medical staff members. Compounding matters, the length of the surgical time is directly correlative to the risk of infection to the patient. Furthermore, the surgery time directly translates to already increasing medical costs. In other words, the longer the surgery, the higher the costs to the patient and medical insurance companies. Accordingly, there is a need to improve precision of the surgery, decrease surgery duration, and lower radiation exposure that is currently required.

As an overview, in one embodiment, the device and method shown and/or described herein is applied to guided growth surgery in pediatric orthopedics. Guiding growth by harnessing the ability of growing bone to undergo plastic deformation is one of the oldest orthopedic principles. Correction of deformity remains a major part of the workload for pediatric orthopedic surgeons and recently, along with developments in limb reconstruction and computer-directed frame correction, there has been renewed interest in surgical methods of physeal manipulation or ‘guided growth’. Manipulating natural bone growth to correct a deformity is appealing, as it allows gradual correction by minimally invasive means.

FIG.1A is a perspective view of a portion of apatient100, and an orthopedic implant positioning system110 (sometimes hereinafter referred to simply as a “positioning system”). The orthopedicimplant positioning system110 can be used in various orthopedic surgical procedures to repair, correct, guide and/or steer various orthopedic structures in the body of thepatient100. Additionally, or in the alternative, the orthopedicimplant positioning system110 can be used in various orthopedic surgical procedures following repair, etc., of the orthopedic structures. The design of the orthopedicimplant positioning system110 can be varied depending upon the specific orthopedic structures involved.

In the embodiment illustrated inFIG.1A, the orthopedicimplant positioning system110 includes an orthopedic implant112 (illustrated in phantom and hereinafter sometimes referred to simply as an “implant”) and an orthopedic implant positioning device114 (hereinafter sometimes referred to simply as a “positioning device”). In the embodiment illustrated inFIG.1A, theimplant112 is shown in an attached position relative to thepositioning device114. Although the description herein focuses primarily on aphysis102 of afemur104 of thepatient100, and on controlling growth of thefemur104, it is understood that the orthopedic implant positioning system110 (and described methods herein) can be used to placeorthopedic implants112 for repair, correction or fracture work at any suitable anatomical region of the body of thepatient100. Stated another way, the description of the orthopedicimplant positioning system110 relative to thephysis102 of thefemur104 is not intended to be limiting in any manner, but rather serves to be representative of the types of procedures in which the orthopedicimplant positioning system110 can be used. As used herein, the term “femur” and “bone” can be used interchangeably, although it is understood that the term “bone” can include bones other than the femur.

In various embodiments, theimplant112 is secured to thefemur104 of thepatient100 during the orthopedic surgical procedure. Theimplant112 can influence or otherwise control growth of the femur104 (including the physis102) depending upon the needs of thepatient100. In the embodiment illustrated inFIG.1A, theimplant112 can include a rigid plate having one or morephysis positioner apertures116 and/or one ormore fastener receivers118. Theimplant112 illustrated inFIG.1A is somewhat figure-8 shaped, and includes onephysis positioner aperture116 and twofastener apertures118. Alternatively, theimplant112 can include greater or fewer than onephysis positioner aperture116, and/or greater or fewer than twofastener apertures118. Theimplant112 can have any suitable configuration that suits the design requirements of the orthopedicimplant positioning system110 and/or the needs of thepatient100.

Thephysis positioner aperture116 is configured to be positioned relative to thefemur104 of thepatient100 so that thephysis positioner aperture116 is directly over thephysis102. Thephysis positioner aperture116 selectively receives atissue locator120 that extends through at least a portion of thepositioning device114 to the desired tissue, such as thephysis102, as described in greater detail herein. With this design, theimplant112 can be properly positioned relative to thephysis102 of thefemur104 during the surgical procedure. In one embodiment, thephysis positioner aperture116 can be centrally located on theimplant112. In certain embodiments, thephysis positioner aperture116 can be positioned directly between and/or equidistant from at least two of thefastener receivers118 in embodiments that include at least twofastener receivers118.

Thefastener receivers118 are each configured to receive oneorthopedic fastener122 that then extends into thefemur104 of thepatient100. As used herein theorthopedic fasteners122 can be referred to as a “first orthopedic fastener”, a “second orthopedic fastener”, etc. It is understood that this is for ease of discussion only, and that any orthopedic fastener can be the first orthopedic fastener, the second orthopedic fastener, etc.

Thefastener receivers118 can be either threaded or non-threaded. In various embodiments, thefastener receivers118 can be angled or otherwise configured to generate compression (or tension) in thefemur104 as desired depending upon the needs of thepatient100 following placement of theorthopedic fasteners122.

In certain embodiments, theimplant112 can be partially or entirely formed from a metal material that provides sufficient rigidity on its own. Alternatively, theimplant112 can be at least partially formed from another suitably rigid material, such as ceramics, composites, or any another suitable material or materials. Still alternatively, theimplant112 can be formed from a flexible and/or resilient material. Further, the dimensions of theimplant112 can be varied to suit the design parameters of thepositioning system110 and/or the needs of thepatient100.

The orthopedicimplant positioning device114 can serve one or more of a variety of functions. For example, in various non-exclusive embodiments, during the orthopedic surgical procedure, thepositioning device114 can, without limitation, retract skin142 (illustrated inFIG.1E) and/or various other tissues of thepatient100, can guide theorthopedic fasteners122 to extend into and through thefastener receivers118 and into thefemur104, can releasably secure and/or position theimplant112, can facilitate use of an imaging system148 (illustrated inFIG.1F) to more accurately position theimplant112, and/or can locate previously positionedimplants112 and their respectiveorthopedic fasteners122 so that a previously-placedimplant112 can be more quickly and effectively removed, among other functions. Two or more of the aforementioned functions can be performed concurrently during use of thepositioning device114.

The design, configuration and/or functionality of thepositioning device114 can vary. In the embodiment illustrated inFIG.1A, thepositioning device114 can include one or more of thetissue locator120, one or more of the orthopedic fasteners122 (twoorthopedic fasteners122 are illustrated inFIG.1A), one or more implant aligners124 (oneimplant aligner124 is illustrated inFIG.1A), adevice body126, animplant attacher128, one or more positioner handles130, and/or one ormore body positioners132.

Thetissue locator120 can first be used to locate thephysis102, prior to positioning the remainder of thepositioning system110. Once thetissue locator120 is positioned at thephysis102, thepositioning system110 can be positioned over thetissue locator120 so that thetissue locator120 extends through theimplant attacher128 which is positioned at least partially within thedevice body126.

The specific design of thetissue locator120 can vary. In one embodiment, thetissue locator120 can extend through theimplant attacher128 along anattacher axis140 of theimplant attacher128. Alternatively, thetissue locator120 can extend through thedevice body126 via an aperture or structure other than theimplant attacher128. Non-exclusive examples of thetissue locator120 can include a K-wire, a needle or another suitably rigid structure (wire or otherwise) that can contact thephysis102 without damaging such tissue. In one embodiment, thetissue locator120 can be threaded. Alternatively, thetissue locator120 can be non-threaded. Because thephysis102 is somewhat softer and less rigid than the boney portion of thefemur104, a user of thepositioning system110 can insert thetissue locator120 through thedevice body126 to check the relative hardness or softness of thefemur104 in order to locate thephysis102.

Theimplant aligner124 cooperates with thetissue locator120 to define the location/orientation of thephysis102 so that proper placement of theimplant112 can be achieved. Any number ofimplant aligners124 can be used to determine the orientation of thephysis102. In one embodiment, theimplant aligner124 can extend through at least a portion of thedevice body126 to locate thephysis102. Non-exclusive examples of theimplant aligner124 can include a K-wire, a needle or another suitably rigid structure (wire or otherwise) that can contact thephysis102 without damaging such tissue. Theimplant aligner124 and thetissue locator120 define a line that establishes an orientation of thephysis102. Once the orientation of thephysis102 has been established by theimplant aligner124 and thetissue locator120, thedevice body126 can be rotated so that thefastener receivers118 of theimplant112 span over either side of thephysis102. In this manner, the orthopedic fasteners can be inserted into thefemur104 on either side of thephysis102 without damaging thephysis102.

Thedevice body126 can retract the tissues (skin, connective tissue, muscle, adipose tissue, etc.) of the patient so that theimplant112 can be properly positioned relative to thefemur104. Additionally, thedevice body126 provides guidance for theorthopedic fasteners122 that secure theimplant112 to thefemur104. The design of thedevice body126 can vary. In one embodiment, thedevice body126 can have a somewhat frustoconical configuration such that a portion of the device body that is positioned subcutaneously (within the patient100) has a larger footprint that that which extends outside of thepatient100. Alternatively, thedevice body126 can have a somewhat cylindrical configuration, an hourglass configuration, a pyramidal configuration, a diamond-shaped configuration, or any other suitable configuration so that the device body can serve one or more of the purposes disclosed herein.

Thedevice body126 can be formed from any suitable materials, such as metal, ceramic, composite materials, various plastics, compostable materials or rubberized materials, or another suitable material or combination of materials. In an alternative embodiment, the device body can be inflatable so that retraction of the tissues necessary for the orthopedic surgical procedure can be better controlled and a smaller incision can be used.

In certain embodiments, thedevice body126 can include one or more of one or more aligner apertures134 (twolocator apertures134 are illustrated inFIG.1A), one or more fastener guides136 (two fastener guides136 are illustrated inFIG.1A) and anattacher receiver138.

Eachaligner aperture134 receives and guides acorresponding implant aligner124 in a direction through thedevice body126. Thealigner aperture134 can be any suitable shape or configuration. The positioning of thealigner aperture134 can vary but should cooperate with the positioning of thetissue locator120 to establish a line that defines the position of thephysis102.

Eachfastener guide136 guides a correspondingorthopedic fastener122 through thedevice body126 to extend into one of thefastener receivers118 and into thefemur104 of thepatient100. In one embodiment, the fastener guides136 can be substantially tubular or cylindrical in configuration. Alternatively, the fastener guides136 can have a somewhat conical or frustoconical configuration, or any other suitable configuration. In certain embodiments, the fastener guides136 can be angled relative to one another. Stated another way, the fastener guides136 can be non-parallel with one another. Alternatively, the fastener guides136 can be parallel with one another.

Theattacher receiver138 receives theimplant attacher128. At least a portion of theimplant attacher128 is movably positioned within theattacher receiver138 during at least part of the orthopedic surgical procedure. In certain embodiments, theimplant attacher128 movably extends through thedevice body126 along anattacher axis140. The implant attacher128 can also, or alternatively, rotate within theattacher receiver138 as needed. The implant attacher128 can releasably engage thephysis positioner aperture116 of theimplant112. The implant attacher128 can thereby releasably secure theimplant112 to theimplant attacher128 and/or thedevice body126 during positioning and/or securing of theimplant112 relative to thefemur104 of thepatient100. Once theimplant112 has been positioned, theimplant attacher128 can release theimplant112. In one embodiment, theimplant attacher128 can selectively threadedly secure theimplant112 during positioning and/or securing of theimplant112 to thefemur104. With this design, once theimplant112 has been positioned and/or secured to thefemur104, theimplant attacher128 can be unscrewed from theimplant112.

The positioner handles130 can be held by the user during positioning of thepositioning system110 relative to thepatient100. The positioning handles130 can extend away from thepositioning device114 for leverage and/or for the user to more safely position thepositioning system110 while radiographs may be taken so that the user is less subjected to harmful radiation. The positioner handles130 can be removable or fixed. In one embodiment, at least one of the positioner handles130 can include glass balls150 (illustrated inFIG.1F) or other components that can cooperate with an imaging system148 (illustrated inFIG.1F).

Thebody positioner132 assists in aligning and/or positioning thedevice body126 relative to one or more known structures within the body of thepatient100. Thebody positioner132 can serve as a visual aid for the user by including one or more visual indicia that can be used to better position thedevice body126, and thus theimplant112 relative to thephysis102 of thefemur104. Additionally, or in the alternative, thebody positioner132 can cooperate with the imaging system148 (illustrated inFIG.1F) to better position thedevice body126, and thus theimplant112, relative to thefemur104.

FIG.1B is a perspective view of a portion of thepatient100 and the orthopedicimplant positioning system110 illustrated inFIG.1A. In the embodiment illustrated inFIG.1B, theorthopedic implant112 is shown in an attached position relative to the orthopedicimplant positioning device114. InFIG.1B, theimplant112 has been positioned relative to thephysis102, and theorthopedic fasteners122 have been secured to thefemur104. In one embodiment, theorthopedic fasteners122 can be threadedly secured to thefemur104. Alternatively, theorthopedic fasteners122 can be secured to thefemur104 by another suitable method. In some embodiments, theorthopedic fastener122 can include a Torx screw or another suitable type of screw. In one embodiment, theorthopedic fasteners122 can cooperate with thefastener receivers118 in a non-locking manner. Alternatively, theorthopedic fasteners122 can cooperate with thefastener receivers118 in a locking manner. In the embodiment illustrated inFIG.1B, theimplant attacher128 is still attached to theimplant112.

FIG.1C is a perspective view of a portion of thepatient100 and the orthopedicimplant positioning system110 illustrated inFIG.1A. InFIG.1C, theorthopedic implant112 is shown in a detached position relative to the orthopedicimplant positioning device114. In other words, once theorthopedic fasteners122 have secured theimplant112 to thefemur104, theimplant attacher128 can be unthreaded from thephysis positioner aperture116 of theimplant112, and thepositioning device114 can be removed from thepatient100.

FIG.1D is a top view of a portion of the orthopedicimplant positioning device114 illustrated inFIG.1A. In the embodiment illustrated inFIG.1D, the fastener guides136 are shown angled away from theattacher receiver138. With this design, the orthopedic fasteners122 (illustrated inFIG.1A) will penetrate the femur104 (illustrated inFIG.1A) at opposing angles to provide compression of thefemur104. In alternative embodiments, the fastener guides136 can be angled toward theattacher receiver138, or can be substantially parallel relative to theattacher receiver138.

FIG.1E is a side view of a portion of the patient and a portion of the orthopedicimplant positioning system110 illustrated inFIG.1A. In this embodiment, thedevice body126 is illustrated at least partially below a surface of theskin142 of thepatient100, while theimplant112 is illustrated in contact with thefemur104.

In the embodiment illustrated inFIG.1E, one or more of the fastener guides136 can be angled relative to theattacher axis140. In one embodiment, at least one of the fastener guides136 can form anangle144 with the attacher axis that is at least 1 degree. In non-exclusive alternative embodiments, at least one of the fastener guides136 can form anangle144 with the attacher axis that is at least 2 degrees, 3 degrees, 5 degrees, 10 degrees, 15 degrees or 20 degrees. Still alternatively, at least one of the fastener guides136 can form anangle144 with the attacher axis that is greater than degrees.

In the embodiment illustrated inFIG.1E, the fastener guides136 can be angled relative to one another on opposite sides of thephysis102. In one embodiment, the fastener guides136 can form anangle146 with one another that is at least 1 degree. In non-exclusive alternative embodiments, the fastener guides136 can form anangle146 with one another that is at least 2 degrees, 3 degrees, 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees or 45 degrees. Still alternatively, the fastener guides136 can form anangle146 with one another that is greater than 45 degrees.

FIG.1F is a front view of a portion of the patient and a portion of the orthopedicimplant positioning system110 illustrated inFIG.1A. In this embodiment, thepositioning system110 includes thebody positioner132 which cooperates with animaging system148 to more accurately position theimplant112 and thepositioning device114 relative to thefemur104 of thepatient100. Theimaging system148 can include any suitable type of system such as an x-ray system, an intraoperative 2D/3D imaging system (such as an O-Arm™ system), CT guidance systems and/or ultrasound.
