## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application is a divisional of U.S. patent application Ser. No. 13/281,016 filed Oct. 25, 2011. The entire disclosure of the above application is incorporated by reference.


FIELD
The present disclosure relates to methods and devices for interosseous membrane reconstruction.
BACKGROUND
This section provides background information related to the present disclosure which is not necessarily prior art.
The interosseous membrane is a broad and thin plane of fibrous connective tissue that separates various different bones of the human body. For example, the long bones of the lower arm and the leg are connected by interosseous membranes. In the arm, an interosseous membrane extends between the radius and ulna to transfer forces from the radius to the ulna and humerus. As the forearm moves from pronation to supination, the interosseous membrane fibers move from a relaxed state to a tense neutral position, and then return to the relaxed state as the forearm enters supination. In the leg, the interosseous membrane extends between the tibia the fibula, running along the crest of each bone. It fulfills many of the same functions in the leg as in the arm.
Tears in the membrane can occur as a result of severe trauma or fracturing of adjacent bone, and may also be created during surgery. To facilitate healing of such tears, pins are often inserted through the bones surrounding the interosseous membrane, such as the radius and the ulna. Use of pins, however, can hinder range of motion, such as pronation and supination of the forearm for example.

DETAILED DESCRIPTION
Example embodiments will now be described more fully with reference to the accompanying drawings.
FIGS. 1A and 1B illustrate an anterior view of a forearm 10 including a radius 12, an ulna 14, and an interosseous membrane 16 extending between the radius 12 and the ulna 14 and across a longitudinal axis A of the forearm 10. The interosseous membrane 16, for example, connects the radius 12 to the ulna 14, facilitates movement of the forearm 10 from pronation to supination, and transfers forces between the radius 12, the ulna 14, and the humerus (not illustrated). The interosseous membrane 16 includes tissue having a plurality of fibers 18.
A first group of fibers 18A generally extend obliquely across the longitudinal axis A from the radius 12 proximally to the ulna 14 distally. A second group of fibers 18B extend obliquely across the longitudinal axis A from the radius 12 distally to the ulna 14 proximally. The second group of fibers 18B is generally smaller than the first group of fibers 18A and is located between the first group of fibers 18A and a distal end 20 of the forearm 10. One skilled in the art will recognize the various orientations of the fibers 18 and the angle of the fibers 18 with respect to the radius 12 and the ulna 14. One skilled in the art will also recognize that no two interosseous membranes are exactly the same, but that the fibers 18 among different patients are similarly orientated, as generally illustrated in FIGS. 1A and 1B, and as described above.
The radius 12 and the ulna 14 can be further connected by a plurality of flexible members, such as sutures 50, which extend through each of the radius 12, the interosseous membrane 16, and the ulna 14. As further described herein, the sutures 50 can be any suitable suture and can be anchored to the radius 12 and the ulna 14 in any suitable manner, such as with a first anchor 52A at the radius 12 and a second anchor 52B at the ulna 14. The sutures 50 supplement the connection between the radius 12 and the ulna 14 provided by the interosseous membrane 16, such as in instances where the interosseous membrane 16 has been damaged due to trauma or during surgery. This damage can include tears in the interosseous membrane 16 or separation of the interosseous membrane from either the radius 12 or the ulna 14.
The sutures 50 each generally extend through a bore 22 formed through the radius 12, the ulna 14, and the interosseous membrane 16. Each of the sutures 50 are generally positioned and orientated to permit natural movement of the radius 12, the ulna 14, and the interosseous membrane 16. For example and with reference to FIG. 1A, suture 50A is orientated such that it extends generally parallel to the interosseous fibers 18 of the first group of interosseous fibers 18A and across the first group of interosseous fibers 18A between the radius 12 and the ulna 14; and suture 50B is orientated such that it extends generally parallel to the interosseous fibers 18 of the second group of interosseous fibers 18B and across the second group of interosseous fibers 18B between the radius 12 and the ulna 14. The suture 50A and the suture 50B are thus each generally orientated at an angle “a” of from about 5° to about 55°, such as about 20° to about 25° or about 40° to about 45°, relative to a line B extending perpendicular to the longitudinal axis A.
The suture 50A is seated in a first bore 22A and the suture 50B is seated in a second bore 22B. Orienting the sutures 50A and 50B parallel to fibers 18 of the first and the second groups of interosseous fibers 18A and 18B respectively generally permits natural movement of the interosseous membrane 16, such as between pronation and supination of the forearm 10, and allows natural loading between the radius 12 and the ulna 14. Such natural movement and loading is not permitted, but is rather restricted by, use of rigid fixation members, such as rigid pins. To stabilize a bone fracture, such as a fracture 28 of the radius 12, the suture 50B can be orientated such that it extends through the fracture 28.
With additional reference to FIG. 1B, the sutures 50 can be provided at a variety of other orientations as well, in addition to or in place of the orientations of sutures 50A and 50B of FIG. 1A. For example, one or more of the sutures 50 can be orientated so as to extend across the interosseous membrane 16 substantially perpendicular to the longitudinal axis A, such as suture 50C seated in bore 22C. Orienting the suture 50C perpendicular to the longitudinal axis A stabilizes relative movement of the radius 12 and the ulna 14 perpendicular to the longitudinal axis A. In other words, the radius 12 and the ulna 14 are stabilized so that they do not move relative to each other perpendicular to the longitudinal axis A. The suture 50C is anchored at the radius 12 with the first anchor 52A and at the ulna 14 with the second anchor 52B.
Any of the sutures 50 can be implanted such that they loop through the forearm 10 and are anchored to only one of either the radius 12 or the ulna 14. For example, both the first anchor 52A and the second anchor 52B of the suture 50D are mounted to the ulna 14. A first portion 50D′ of the suture 50D extends from the first anchor 52A to the radius 12 through a first bore 22D. Upon exiting the first bore 22D at the radius 12, the suture 50D loops back into the radius 12 such that a second portion 50D′′ extends through the radius 12 to the ulna 14 through a second bore 22D′, where the suture 50D is secured by the second anchor 52B. Each of the first bore 22D and the second bore 22D′ are extended substantially perpendicular to the longitudinal axis A, and thus the first and second portions 50D′ and 50D′′ of the suture 50D are perpendicular to the longitudinal axis A as well. While the suture 50D is secured to the ulna 14 with the first anchor 52A and the second anchor 52B, the suture 50D can be reversed such that the first anchor 52A and the second anchor 52B are secured to the radius 12. By looping the suture 50D through the forearm 10 as illustrated, the suture 50D can provide additional stability to the radius 12 and the ulna 14 perpendicular to the longitudinal axis A.
As illustrated in FIG. 1B, suture 50E provides another possible orientation for the suture 50. The suture 50E is orientated such that the first anchor 52A and the second anchor 52B are both anchored to the radius 12. A first portion 50E′ of the suture 50E extends from the first anchor 52A to the ulna 14 through a first bore 22E. Upon exiting the first bore 22E at the ulna 14, the suture 50E loops back into the ulna 14 such that a second portion 50E′′ extends through the ulna 14 to the radius 12 through a second bore 22E′, where the suture 50E is secured by the second anchor 52B. The first bore 22E is angled such that it extends through the interosseous membrane 16 substantially parallel to the fibers 18 of the first group of interosseous fibers 18A. Thus, the first portion 50E′ is also substantially parallel to the fibers 18 of the first group of interosseous fibers 18A. The second bore 22E′ is substantially perpendicular to the longitudinal axis A, and thus the second portion 50E′′ of the suture 50E is perpendicular to the longitudinal axis A. The first portion 50E′ is angled about 5° to about 55° relative to the second portion 50E′′, such as about 20° to about 25° or about 40° to about 45°.
Orienting the second portion 50E′′ generally perpendicular to the longitudinal axis A stabilizes the radius 12 with respect to the ulna 14 perpendicular to the longitudinal axis A and orienting the first portion 50E′ generally parallel to the fibers 18 of the first group of interosseous fibers 18A generally permits natural movement of the radius 12 with respect to the ulna 14, such as during supination and pronation of the forearm 10, and distributes load between the radius 12 and the ulna 14 similar as to how the load would be distributed naturally. Thus, the suture 50E is a dual purpose suture that generally provides two stabilizing effects. First, the first portion 50E′ permits load transfer between the radius 12 and the ulna 14 in a manner similar to that which occurs naturally. The second portion 50E′′ stabilizes the radius 12 and the ulna 14 along the longitudinal axis A so that the radius 12 and the ulna 14 do not move relative to each other perpendicular to the longitudinal axis A.
The forearm 10 can be provided with any combination of the sutures 50A-50E, and is thus not limited to the arrangements illustrated in FIGS. 1A and 1B. For example, each one of the sutures 50A-50E can be included in a single forearm 10. The arrangement of the sutures 50A-50E can be determined by a physician based on, for example, the patient's anatomy, damage to the interosseous membrane 16, and observed orientations of the patient's interosseous fibers 18.
With additional reference to FIG. 2, further details of the suture 50, which generally includes a suture construct or assembly, will be described. The description of the suture 50 generally applies to each of the sutures 50A-50E described above. The suture 50 can generally include a hollow braided suture strand 54 including a first end 56 and a second end 58. The second anchor 52B is approximately equidistant between the first end 56 and the second end 58. The second anchor 52B is generally U-shaped and flexible. The second anchor 52B includes a base 60 and a pair of feet 62, which extend from the base 60. The base 60 is connected to the suture strand 54 in any suitable manner, and may be integral with the suture strand 54 as illustrated.
The first anchor 52A is between the first end 56 of the suture strand 54 and the second anchor 52B. The first anchor 52A includes a base 64 and a pair of feet 66. Integral with the base 64 and the suture strand 54 is a sleeve portion 68 of the suture 54 that includes a first opening 70 and a second opening 72 between braided fibers that is opposite to the first opening 70. The second end 58 of the suture strand 54 is inserted through the sleeve 68 such that the suture strand 54 enters the sleeve 68 through the first opening 70 and exits the sleeve 68 through the second opening 72.
The suture 50 is a knotless, self-locking suture. As the first and second ends 56 and 58 are pulled, friction between the interior of the sleeve 68 and the portion of the suture strand 54 located within the sleeve 68 causes the suture 50 to “automatically” lock in a reduced size or diameter configuration in which tension is maintained without use of a knot. The suture 50 is similar to the self-locking suture construct 300A of FIG. 15 of U.S. application Ser. No. 12/915,962 filed on Oct. 29, 2010, titled Method and Apparatus for Securing Soft Tissue to Bone, and assigned to Biomet Sports Medicine, LLC, the disclosure of which is incorporated herein by reference. Additional description of the suture 50 is thus included in U.S. application Ser. No. 12/915,962. Additional sutures that can be used in accordance with the present teachings include those disclosed in U.S. Pat. No. 7,658,751, which issued on Feb. 9, 2010 and is assigned to Biomet Sports Medicine, LLC, Warsaw, Ind. The disclosure of U.S. Pat. No. 7,658,751 is incorporated herein by reference.
The suture 50 can be replaced with any suitable biocompatible fastening device that will permit natural movement of the interosseous membrane 16. For example and with reference to FIG. 3, a suture 80 can be used. The suture 80 is a self-locking suture that includes a hollow, braided suture strand 82 with a first end 84 and a second end 86. A sleeve portion 88 of the suture 80 is located about halfway between the first end 84 and the second end 86. The sleeve 88 includes a first opening 90 and a second opening 92 between braided fibers. The first end 84 is inserted into the sleeve 88 through the second opening 92 and passed through the sleeve 88 such that the first end 84 extends out through the first opening 90 of the sleeve 88. The second end 86 is inserted into the sleeve 88 through the first opening 90 and passed through the sleeve 88 such that the second end 86 extends out through the second opening 92 of the sleeve 88. Inserting the first and the second ends 84 and 86 through the sleeve 88 causes the suture strand 82 to form a first loop 94 including a first anchor 98 and a second loop 96 including a second anchor 99. As the first end 84 and the second end 86 are pulled through the sleeve 88, friction in the sleeve 88 causes the suture 80 to “automatically” lock in a reduced size or diameter configuration in which tension is maintained without use of a knot. The suture 80 is similar to the self-locking suture construct 250 of FIG. 13 of U.S. application Ser. No. 12/915,962, the disclosure of which has been incorporated herein by reference. Additional description of the suture 80 is thus included in U.S. application Ser. No. 12/915,962.
In addition to the sutures and suture constructs described herein and incorporated herein by reference, any other suitable suture, suture construct, knit, or flexible member, such as a Nitinol strand, can be inserted in the bores 22 to connect the radius 12 and ulna 14 in a manner that will transfer loads between the radius 12 and ulna 14, provide at least near natural range of motion between the radius 12 and ulna 14, and stabilize the radius 12 and ulna 14 along the longitudinal axis A such that neither the radius 12 nor the ulna 14 move relative to each other perpendicular to the longitudinal axis A.
The anchors 52A, 52B, 98, and 99 are all configured to expand when compressed against bone so as to anchor to an exterior of the bone. For example and with reference to FIG. 4, as the suture strand 54 is pulled away from an outer surface 24 of the ulna 14 through the first bore 22A, the second anchor 52B compresses against the outer surface 24 and expands to anchor the suture 50 to the ulna 14.
With additional reference to FIG. 5, any one or more of the sutures 50 can be anchored at an interior of the radius 12 or the ulna 14 with an anchor 110. The anchor 110, which can be similar to the anchor 52 but collapsed to fit within the first bore 22A, expands to form an anchoring mass 112 upon tightening of suture strands 114 to thereby secure the anchor 110 to the radius 12 or ulna 14. The anchor 110 is similar to the anchor 150 of the suture construct 184 disclosed in U.S. application Ser. No. 12/915,962, the disclosure of which has been incorporated herein by reference. Additional description of the anchor 150 is thus included in U.S. application Ser. No. 12/915,962.
With reference to FIG. 6, any of the sutures 50, any of the other sutures described herein, and any of the sutures incorporated by reference can be secured to the radius 12 or the ulna 14 with a knot 120 having an outer diameter larger than the bore that the suture is seated within, such as the first bore 22A.
With reference to FIG. 7, any of the sutures 50, any of the other sutures described herein, and any of the sutures incorporated by reference can be secured to the radius 12 or the ulna 14 with a lever anchor 130 movable between a non-active position and an active position. In the non-active position, the lever anchor 130 is orientated such that is can pass through the bore that the suture is seated within, such as the first bore 22A. In the activated position, illustrated in FIG. 7, the lever anchor 130 extends across the bore at an exterior of the radius 12 or ulna 14 to secure the anchor 130 to the radius 12 or ulna 14. As an alternative to the illustrated anchor 130, any other suitable anchor member or button can be mounted to suture strands 14.
With additional reference to FIG. 8, implantation of the suture 50A in the forearm 10 will be described. The first bore 22A can be drilled using any suitable guide, such as first drill guide 150. The first drill guide 150 generally includes a body 152 that defines a through hole 154 configured to receive a suitable cutting implement, such as drill bit 156 of a drill 158. Extending from the body 152 is a guide arm 160 sized and configured to span the forearm 10. At an end of the guide arm 160 opposite to the body 152 is a guide pin 162 that is suitable to engage an opposite side of the forearm 10 to assist in stabilizing the first drill guide 150 on the forearm 10.
The first drill guide 150 is orientated such that the through hole 154 is aligned parallel to the fibers 18 of the second group of interosseous fibers 18A. The drill 158 is positioned such that the drill bit 156 extends through the through hole 154 to engage the ulna 14. The drill 158 is then activated to drill the first bore 22A through the ulna 14, past the interosseous membrane 16, and through the radius 12. Drilling the first bore 22A past the interosseous membrane 16 can include through the interosseous membrane. The first drill guide 150 can be oriented in the opposite direction illustrated in FIG. 8, such that the body 152 abuts the radius 12 and the guide pin 162 abuts the ulna 14. The drill guide 150 can also be used to drill any of the other bores 22B-22E, as one skilled in the art will recognize.
With additional reference to FIG. 9, a pin 170 can be used to guide the suture 50A through the first bore 22A and assist in initially stabilizing the radius 12 in relation to the ulna 14. The pin 170 includes an elongated shaft 172, a pointed distal end 174, and a hook 176 proximate to the distal end 174. The pin 170 is inserted through the first bore 22A such that the pointed distal end 174 and hook 176 of the pin 170 exit the forearm 10 through the radius 12. With additional reference to FIG. 10, the guide pin 162 hooks the suture 50A to pull the suture 50A into the first bore 22A. With the suture 50A seated within the first bore 22A such that the first anchor 52A is at an outer surface 26 of the radius 12 and the second anchor 52B is at the outer surface 24 of the ulna 14, the first end 56 and the second end 58 of the suture strand 54 are pulled to tighten and adjustably compress the first and second anchors 52A and 52B against the radius 12 and the ulna 14 respectively, as illustrated in FIG. 11.
With additional reference to FIG. 12, a second drill guide is generally illustrated at reference numeral 210. The drill guide 210 includes a body 212 with a bone engaging surface 214. The bone engaging surface 214 is generally planar and includes a plurality of bone engagement teeth 216, which are pointed to facilitate secure engagement with either the radius 12 or the ulna 14. The second drill guide 210 defines a first through hole 218 and a second through hole 220. The first through hole 218 includes a first center axis C that is generally oblique to the bone engaging surface 214. The second through hole 220 includes a second center axis D that is generally perpendicular to a plane defined by the planar bone engaging surface 214. The first center axis C is orientated at an angle b, which is about 5° to about 55° relative to the second center axis D, such as about 20° to about 25° or about 40° to about 45°.
The angle b between the first center axis C and the second center axis D can be any suitable angle corresponding to the desired orientation of bores to be drilled in the forearm 10. For example, to drill the first bore 22E and the second bore 22E′ as illustrated in FIG. 1B, the first through hole 218 will be angled from the second through hole 220 at an angle that corresponds to an angle at which the first bore 22E is to be angled from the second bore 22E′, such as at an angle of from about 5° to about 55°, such as about 20° to about 25° or about 40° to about 45°. Thus, the second drill guide 210 can be used to form the first and second bores 22E and 22E′ respectively for use in providing at least the following two different types of forearm stability: 1) stability along the longitudinal axis A provided by the second portion 50E′′ of the suture 50E extending through the second bore 22E′ to prevent the radius 12 from moving relative to the ulna 14 perpendicular to the longitudinal axis A; and 2) load transfer stability, as well as natural range of motion during pronation and supination, provided by the first portion 50E′ of the suture 50E extending through the first bore 22E.
With additional reference to FIG. 13, a pin guide is generally illustrated at reference numeral 250. The pin guide 250 generally includes a body 252 and a planar bone engaging surface 254. The body 252 generally defines a hemispherical guide surface 256. The planar bone engaging surface 254 includes a plurality of fixation members 258 that are sharpened and protrude from the bone engaging surface 254. The fixation members 258 can engage either the radius 12 or the ulna 14 to affix the pin guide 250 thereto.
With additional reference to FIGS. 14A and 14B, the second drill guide 210 can be used to drill, for example, the first bore 22E and the second bore 22E′ to receive the suture 50E. The second drill guide 210 is mounted to the outer surface 24 of the ulna 14 such that the bone engagement surface 214 contacts the outer surface 24 and the bone engagement teeth 216 are pressed into and through the outer surface 24. The drill bit 156 is inserted through the first through hole 218 and rotated by the drill 158 to form the first bore 22E. The drill bit 156 is inserted through the second through hole 220 and rotated by the drill 158 to form the second bore 22E′.
With reference to FIGS. 15 and 16, after the first bore 22E and the second bore 22E′ have been drilled, the pin guide 250 can be mounted to the outer surface 24 of the ulna 14 such that the pin guide 250 is aligned with the first bore 22E and the second bore 22E′. To position the suture 50E in the first and second bores 22E and 22E′, a flexible guide pin 270 can be used, but is optional as one skilled in the art will recognize that the suture can be guided through the first and second bores 22E and 22E′ in any suitable manner, such as without a guide. The flexible guide pin 270 includes a pointed distal end 272 and a hook 274 proximate to the pointed distal end 272. The flexible guide pin 270 is inserted into the first bore 22E at the radius 12 and pushed through the first bore 22E such that it reaches the pin guide 250. The pin guide 250 contacts the hemispherical guide surface 256, which directs the pointed distal end 272 of the flexible guide pin 270 into the second bore 22E′. As illustrated in FIG. 15, the flexible guide pin 270 then is pushed through the second bore 22E and exits the second bore 22E′ at the outer surface 26 of the radius 12. The suture 50E is connected to the hook 274 and the flexible guide pin 270 is then pulled back through the second bore 22E′ and the first bore 22E to position the suture 50E in both the first bore 22E and the second bore 22E′, as illustrated in FIG. 16. With further reference to FIG. 16, the first end 56 and the second end 58 of the suture strand 54 are pulled to secure the suture 50E in the forearm 10. Rather than a single suture 50E extending through both the first bore 22E and the second bore 22E′, separate sutures can be secured within each of the first bore 22E and the second bore 22E′.
Any two or more of the following can be provided in a kit: the first drill guide 150, the guide pin 170, the second drill guide 210, the pin guide 250, or flexible guide pin 270, each of which may be included in the kit in a plurality of different sizes and/or shapes. The kit may also include one or more of the sutures 50, as well as any of the other sutures described herein or incorporated by reference, or any other suitable fastening device.
The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described.
