PCT / US25 / 32413 05 June 2025 (05.06.2025)Nutek-0017 PCTEXTERNAL FIXATOR FOR DISTAL RADIUS FRACTUREPRIORITYThis application claims priority to U.S. Provisional Patent Application Serial No. 63 / 658,0355 filed June 10, 2024, the contents of which are hereby incorporated by reference in its entirety.FIELD OF THE INVENTION
[0001] The present invention relates to devices for external fixation of fractured bones, and / or bone fragments.10BACKGROUND
[0002] The fracture of the distal radius is one of the most common human fractures , occurring in as many as 350,000 people per year in the United States alone. Conventional processes for maintaining bones in proper alignment during the subsequent healing process involves applying and maintaining an extension force across the fracture, with ligamental taxis being relied upon to hold the bones in place. The process for treating a fractured distal radius is described in the 1901 edition of Gray’s Anatomy in the following manner, “The treatment consists of flexing the forearm, and making a powerful extension from the wrist and elbow, depressing at the same time the radius side of the hand, and retaining the parts in that position20 by well -padded pistol-shaped splints.”
[0003] A common method for the treatment of a fractured distal radium involves the use of standard immobilizing case techniques, preventing movement of the radiocarpal joint throughout the course of rehabilitation. A problem with this method is that it sometimes results in inadequate internal fixation, which can cause deformity, pain, and disability.25
[0004] Another method for treating a fractured distal radius involves external pin fixation. This process involves the surgical insertion of skeletal traction pins on both sides of the fracture, with a frame being connected to the pins for immobilizing the bones, and for holding them together until the fracture is mended. Initial structures and methods for applying external pin fixation for the treatment of a fractured distal radius provide for the immobilization of the radiocarpal joint, so that the hand cannot be flexed. While this type of fixation often provides an improvement over conventional casting techniques in the management of severe fractures of the distal radius, immobilization of the radiocarpal joint during the treatment period typically results in a long period of stiffness and disability after the external fixation devices is removed. Typically, the external fixation device is left in place during the healing process for six to eight35 weeks. After the fixation device is removed, three to six months are required for the patient toPCT / US25 / 32413 05 June 2025 (05.06.2025) regain motion of his hand.
[0005] Subsequent structures and methods have been developed to provide adequate fixation during the healing process while allowing flexure in the radiocarpal joint. Using these newer structures and methods, patients have been able to gain immediate use of the joint after surgery.5
[0006] An example of a fixation device and fixation method that provides adequate fixation and allows flexure in the radiocarpal joint is described in U.S. Pat. No. 6,585,736, the disclosure of which is incorporated herein by reference. U.S. Pat. No. 6,585,736, describes a fixation that is configured to provide external fixation of a fractured distal radium by including a first10 number of holes for pins extending downward from the fixture into one or more fragments, rods that extend downward and hold pins laterally into one or more bone fragments, and a second number of holes for pins extending downward from the fixture into the shank of the radius. The fixture also include a sliding block through which rods extend to hold pins directed laterally into the fragments. A sliding plate including a number of holes aligned with the first number of holes is moved by a pair of setscrews to clamp the pins extending through the first number of holes. The second number of holes include a hole within a sliding structure allowing a single pin to be moved with a fixture to provide extension between the fragments and the shank of the radius.
[0007] In a more recent fixation device described in U.S. Pat. No. 8,075,560, the disclosure of which is incorporated herein by reference, external fixation of a fractured distal radium is achieved by (i) a first pin mounting block having parallel, vertically-extending apertures therein for pins extending vertically downward from the first pin mounting block, at a fixed 90° angle to the first pin mounting block, into one or more bone fragments, and (ii) a second pin mounting block extending perpendicular to the first pin mounting block, and having horizontally¬25 extending apertures therein for pins extending laterally into one or more bone fragments.
[0008] Efforts continue to further develop fixation devices that provide one or more benefits over known fixation devices. What is needed is more functionally effective structure that provide enhanced orientation of pins extending vertically and horizontally from the fixation devices. Such a structure and method would still allow mobility of the hand and wrist while presenting fewer surfaces to get caught on other objects and being more cost effective due to it having parts.SUMMARY OF THE INVENTION
[0009] The present invention is directed to external fixators comprising a fixator body,35 wherein the fixator body has an elongated frame element at one end and a first pin mountingPCT / US25 / 32413 05 June 2025 (05.06.2025) block at the opposite end. A second pin mounting block is orthogonally connected to one side of the fixator body. The external fixator provides a more stable structure to fix a plurality of fragments (or segments) of a fractured distal radius bone with respect to the radius bone shaft.
[0010] The fixator body comprises the elongated frame element at one end and the first pin5 mounting block at the opposite end of the fixator body. The fixator body is externally attached to the distal radium bone by one or more mounting bone pins housed within the elongated frame, both screwed and locked into the radius bone shaft, above the radius bone and the wrist. The fixator body is thus mounted parallel to the radium bone and above the radius bone extending over the wrist area of the patient.10
[0011] In some embodiments, the external fixators of the present invention comprise a fixator body that comprises (a) a first pin mounting block extending along an upper surface at a front end of the fixator body, (b) an elongated frame element extending from the first pin mounting block along the upper surface to a rear end of the fixator body, and (c) a plurality of mounting block apertures extending through the first pin mounting block from upper surface to a lower surface of the fixator body, each mounting block aperture comprising (i) a mounting block aperture inlet along the upper surface, (ii) a mounting block aperture outlet along the lower surface, and (iii) a mounting block aperture inner side surface extending between the mounting block aperture inlet and the mounting block aperture outlet, wherein the mounting block aperture outlet has a cross-sectional area AAOMB that is smaller than a cross-sectional area AAIMB of the mounting block aperture inlet. Each mounting block aperture is designed to allow a given vertically-extending fragment pin, used to fix bone chips in place, to be (1) angularly disposed at an acute angle of up to about thirty degrees (30°) from a normal line N perpendicular to the first pin mounting block, (2) screwed into a bone fragment, and (3) locked into place along the first pin mounting block by tightening a channel-containing clamping25 component onto a spherical pin holder containing the vertically-extending fragment pin.
[0012] In some embodiments, the external fixators of the present invention comprise a fixator body that comprises (a) a first pin mounting block extending along an upper surface at a front end of the fixator body, (b) an elongated frame element extending from the first pin mounting block along the upper surface to a rear end of the fixator body, and (c) a plurality of mounting block apertures extending through the first pin mounting block from upper surface to a lower surface of the fixator body, each mounting block aperture comprising (i) a mounting block aperture inlet along the upper surface, (ii) a mounting block aperture outlet along the lower surface, and (iii) a mounting block aperture inner side surface extending between the mounting block aperture inlet and the mounting block aperture outlet, wherein each first pin mounting35 block aperture is designed to allow a given vertically-extending fragment pin, positionedPCT / US25 / 32413 05 June 2025 (05.06.2025) therein, to be angularly disposed at an acute angle of greater than 0 up to about thirty degrees (30°) from a normal line N perpendicular to the first pin mounting block.
[0013] In some embodiments, the external fixators of the present invention comprise a second pin mounting block that is attachable to the fixator body along a side edge of the first5 pin mounting block, and comprises a plurality of second pin mounting block apertures extending through the second pin mounting block from a front surface to a rear surface of the second pin mounting block, wherein each second pin mounting block aperture comprises (i) a second pin mounting block aperture inlet along the front surface, (ii) a second pin mounting block aperture outlet along the rear surface, and (iii) a second pin mounting block aperture10 inner side surface extending between the second pin mounting block aperture inlet and the second pin mounting block aperture outlet, wherein the second pin mounting block aperture outlet has a cross-sectional area AAOSMB that is smaller than a cross-sectional area AAISMB of the second pin mounting block aperture inlet. Each second pin mounting block aperture is designed to allow a given horizontally-extending fragment pin, used to fix bone chips in place, to be (1) angularly disposed at an acute angle of up to about thirty degrees (30°) from a normal line N perpendicular to the second pin mounting block, (2) screwed into a bone fragment, and (3) locked into place along the second pin mounting block by tightening a channel-containing clamping component onto a spherical pin holder containing the horizontally-extending fragment pin.
[0014] Because of the location of the first pin mounting block and the second mounting pin block and their orthogonal relationship, as well as the angular orientation range provided by the first pin mounting block apertures, and the second pin mounting block apertures, the distal radium bone fragments can be fixed in place in multiple dimensions.
[0015] Using the external fixator devices of the present invention, for example, as an external25 fixator for a radium fracture, allows for immediate post operative wrist and finger function and motion from dorsal to volar function, radial to ulnar deviation, supination, and pronation.

[0048] The features of the present external fixator devices, individual components of the35 external fixator devices, and methods of using the external fixator devices are set forth in partPCT / US25 / 32413 05 June 2025 (05.06.2025) in the following preferred embodiments. This overview is intended to provide nonhmiting descriptions of the present subject matter and is not intended to provide an exclusive or exhaustive explanation. The preferred embodiments below provide further information about the external fixator devices, individual components of the external fixator devices, and methods5 of using the external fixator devices of the present invention as described herein.DETAILED DESCRIPTION OF THE INVENTION
[0049] The present invention is directed to external fixators that are designed for surgical attachment to two or more bones within a patient, such as the shank portion of the radius bone,10 and other bones within the wrist of a patient.
[0050] The present invention is further directed to external fixator kits comprising numerous kit components to form a customized external fixator.
[0051] The present invention is even further directed to methods of making and using external fixators and external fixator kits to position and set numerous bones of a patient into15 a set position for healing.
[0052] FIGS. 1-27C provide examples of various components that can be used to form external fixators of the present invention. As shown in FIG. 1, exemplary external fixator 100 comprises a fixator body 13 that comprises (a) a first pin mounting block 23 extending along an upper surface 131 at a front end 132 of the fixator body 13, (b) an elongated frame element 12 extending from first pin mounting block 23 along the upper surface 131 to a rear end 133 of the fixator body 13, and (c) a plurality of first pin mounting block apertures 26 extending through first pin mounting block 23 from upper surface 131 to a lower surface 135 of the fixator body 13, each first pin mounting block aperture 26 comprising (i) a mounting block aperture inlet 261 along the upper surface 131, (ii) a mounting block aperture outlet 262 along the lower25 surface 135, and (iii) a mounting block aperture inner side surface 263 extending between the mounting block aperture inlet 261 and the mounting block aperture outlet 262, wherein the mounting block aperture outlet 262 has a cross-sectional area AAOMB that is smaller than a cross-sectional area AAIMB of the mounting block aperture inlet 261.
[0053] As further shown in FIGS. 1 and 14, exemplary external fixator 100 also comprises at least the following components: (i) a second pin mounting block 43 extending perpendicular (about 90°) to and below the fixator body 13; (ii) an elongated frame element sleeve 70; (iii) a device spacer 126; (iv) first channel-containing clamping components 40; (v) second channelcontaining clamping components 40’; (vi) first spherical pin holders 39; (vii) various boneengaging pins 11 / 22 / 22’; and (viii) bolts 80. Each of these components will be described in35 further detail below.PCT / US25 / 32413 05 June 2025 (05.06.2025)
[0054] The external fixators 100 of the present invention are configured for surgical attachment to one or more bones of a patient. As shown in FIG. 1, external fixators 100 of the present invention can be used for surgical attachment to the shank portion of a radius bone 200 (and other bones and / or bone fragments) via (a) one or more vertically-extending bone pins 115 extending downward from the elongated frame element 12 of fixator body 13, with the pointed end 14 of each vertically-extending bone pin 11 being screwed into the bone 200, (b) one or more vertically-extending fragment pins 22 extending downward from the first pin mounting block 23, with the pointed end 24 of each vertically-extending fragment pin 22 being screwed into the bone 200 (or another bone and / or bone fragment), and (c) one or more horizontally -10 extending fragment pins 22’ extending horizontally from a second pin mounting block 43 (i.e., at an angle of from about 50° to about 130° relative to a direction of a given vertically- extending fragment pin 22 extending downward from the first pin mounting block 23), with the pointed end 24’ of each horizontally-extending fragment pin 22’ being screwed into the bone 200 (or another bone and / or bone fragment).
[0055] Each of the one or more vertically-extending fragment pins 22 that extend downward from the first pin mounting block 23 are fixed into place within a given first pin mounting block aperture 26 via a first spherical pin holder 39 and a first channel-containing clamping components 40 as shown, for example, in FIG. 15. A given vertically-extending fragment pin 22 is positioned thru and within a pin mounting hole 52 of a given first spherical pin holder 39, which is then positioned within a given first pin mounting block aperture 26. Once the pin 22 / pin holder 39 combination is positioned relative to bone, a first channel-containing clamping component 40 is positioned within the first pin mounting block aperture 26 so as to clamp the pin 22 / pin holder 39 combination in a “locked” (i.e., “set”) positioned / configuration within first pin mounting block aperture 26, and the first pin mounting block 23.25
[0056] Each of the one or more horizontally-extending fragment pins 22’ that extend horizontally from the second pin mounting block 43 are fixed into place within a given second pin mounting block aperture 46 via (i) a first spherical pin holder 39 (or a second spherical pin holder 39’) and (ii) a first channel-containing clamping component 40 (or a second channelcontaining clamping component 40’). A given horizontally-extending fragment pin 22’ is positioned thru and within a pin mounting hole 52 of a given first spherical pin holder 39 (or a pin mounting hole 52’ of a second spherical pin holder 39’), which is then positioned within a given second pin mounting block aperture 46. Once the pin 22 ’ / pin holder 39 / 39’ combination is positioned relative to bone, a first channel-containing clamping component 40 (or a second channel-containing clamping component 40’) is positioned within the second pin mounting35 block aperture 46 so as to clamp the 227pin holder 39 / 39’ combination in a “locked” (i.e.,PCT / US25 / 32413 05 June 2025 (05.06.2025)“set ) positioned / configuration within second pin mounting block aperture 46, and the second pin mounting block 43.
[0057] Due to the pin positioning ability of the first pin mounting block 23 and the second pin mounting block 43, pins 22 / 22’ within the first pin mounting block 23 and the second pin5 mounting block 43 can be oriented relative to one another at an angle of from about 50° to about 130°. As shown in FIGS. 15 and 23, pins 22 extending vertically from the first pin mounting block 23 and pins 22’ extending horizontally from the second pin mounting block 43 can be oriented along an arc / acute angle of about 40° (desirably, up to about 60°), or about 20° (desirably, up to about 30°) on either side of a normal line N extending through the first pin10 mounting block 23 or the second pin mounting block 43. The range of motion provided for each of pins 22 / 22’ within the first pin mounting block 23 and the second pin mounting block 43 provides a user with more flexibility with regard to positioning of pins 22 / 22’ within the first pin mounting block 23 and the second pin mounting block 43.
[0058] As shown in FIGS. 27A-27C, pins 22 / 22’ within the first pin mounting block 23 and the second pin mounting block 43 can be oriented relative to one another by any desired arc ranging from as little as 50° (desirably, as little as 30°) to as much as 130° (desirably, as much as 150°). FIG. 27A depicts pins 22 / 22’ oriented to have a 130° arc / angle (e.g., 90° + 20° + 20°) between pins 22 / 22’. FIG. 27B depicts pins 22 / 22’ oriented to have a 90° arc / angle (e.g., 90° + 20° - 20°) between pins 22 / 22’. FIG. 27C depicts pins 22 / 22’ oriented to have a 50° arc / angle (e.g., 90° - 20° - 20°) between pins 22 / 22’.
[0059] It should be further noted that each of the one or more vertically-extending bone pins 11 extending downward from the elongated frame element 12 of fixator body 13 are fixed into place within a given elongated frame element aperture 36 via (i) a first spherical pin holder 39 (or a second spherical pin holder 39’) and (ii) a first channel-containing clamping component25 40 (or a second channel-containing clamping component 40’). A given vertically-extending bone pins 11 is positioned thru and within a pin mounting hole 52 of a given first spherical pin holder 39 (or a pin mounting hole 52’ of a second spherical pin holder 39’), which is then positioned within a given elongated frame element aperture 36. Once the pin 11 / pin holder 39 / 39’ combination is positioned relative to bone, a first channel-containing clamping component 40 (or a second channel-containing clamping component 40’) is positioned within the elongated frame element aperture 36 so as to clamp the 11 / pin holder 39 / 39’ combination in a “locked” (i.e. , “set”) positioned / configuration within elongated frame element aperture 36, and the elongated frame element 12 of fixator body 13.
[0060] As shown in FIGS. 16A-16B, both first spherical pin holders 39 and second spherical35 pin holders 39’ independently comprise a pair of ball slots 51 or 51’ extending perpendicularPCT / US25 / 32413 05 June 2025 (05.06.2025) to a pm mounting hole 52 or 52 and inward across the pm mounting hole 52 or 52 and partly across the spherical pin holder 39 or 39’, so that the deformable portion 53 or 53’ is actuated between each end 54 or 54’ of the pin mounting hole 52 or 52’ and the ball slots 51 or 51’ that is nearer to the end 54 or 54’.5

[0063] The configuration shown in FIG. 1 is assembled particularly for treating a distal fracture of the right radius 200. For treating a distal fracture of the left radius, the second pin25 mounting block 43 is positioned along an opposite side edge 235 from that shown in FIG. 1.
[0064] One exemplary method for installing the external fixator 100 to provide both support and extension to a fractured radius 200 comprises the following steps: (1) surgically inserting a vertically-extending bone pin 11 into the shank portion of a radius bone 200, the vertically- extending bone pin 11 extending through (i) an elongated frame element aperture 36, (ii) a spherical pin holder 39 or 39’, (iii) and an elongated frame element sleeve 70; (2) surgically implanting one or more vertically-extending fragment pins 22 into one or more distal fragments of the radius bone 200, the one or more vertically-extending fragment pins 22 extending through (i) one or more first pin mounting block apertures 26, and (ii) one or more first spherical pin holders 39; (3) surgically implanting one or more horizontally-extending35 fragment pins 22’ into one or more distal fragments of the radius bone 200, the one or morePCT / US25 / 32413 05 June 2025 (05.06.2025) horizontally-extending fragment pins 22 extending through (i) one or more second pm mounting block apertures 46, and (ii) one or more second spherical pin holders 39’; (4) adjusting an angular orientation of one or more of the vertically-extending fragment pins 22, the angular orientation being adjustable up to about 30° from a normal line N extending through5 the first pin mounting block 23; and (5) after said adjusting step, locking the vertically- extending fragment pin 22 in a desired angular orientation via a first channel-containing clamping component 40. The order in which pins 11, 22, and 22’ are implanted may be arbitrary, or may be determined by surgical considerations including the exact type of fracture.
[0065] Pins 11, 22, and 22’ are preferably commercially available pins, which are10 conventionally composed of stainless steel. Other portions of the external fixator 100 are preferably composed of thermoplastic resins, with the screws being composed, for example, of nylon, and with the remaining parts being composed, for example, of polycarbonate. This use of thermoplastic material makes it possible to form X-ray images of the bones through the external fixator 100. Furthermore, such materials provide a sufficient combination of strength and resiliency to allow a range of patterns / configurations of vertically-extending fragment pins22 to be clamped simultaneously as described above.Additional EmbodimentsExternal Fixators
