- a bone tunnel 28 is bored in a patient's femur (hereinafter “bone”) 30 by any conventional means. It is understood that the bone tunnel alternatively could be bored in the patient's tibia 32 . In the preferred method of use, the bone tunnel 28 is bored at a right angle relative to the longitudinal axis of the bone 30 .
- the major component of any force that would tend to create graft slippage occurs at a right angle to the device, along the bone's longitudinal axis. The resulting force vector is thus considerably diminished, and thereby far less likely to result in graft slippage.

- the threads 36 a engage the grooves 18 of the body portion 12 , and also the portion of the bone 30 defining the bone tunnel 28 .
- the screw As the screw advances, it exerts forces upward into the bone 30 , and downward on the device 10 , thereby firmly securing the device and graft 34 in the bone tunnel 28 . More specifically, in the upward direction, the force produced by the screw 36 causes the threads 36 a to sink into the bone 30 . Similarly, the downward force on the device 10 causes the spur ends 22 a - 24 a to be driven deeply into the bone 30 , thereby further securing the device in the bone tunnel 28 . Once engaged with the bone 30 , the spurs 22 - 24 prevent undesirable rotational movement by the device 10 (“rotational migration”) that would otherwise be caused by torsional forces associated with the screw's rotation.
- the downward force exerted by the screw 36 on the device 10 also causes the spikes 20 to engage and compress the graft 34 , thereby biasing the graft in the bone tunnel 28 .
- the graft is held at a number of contact points, the ends 20 a , thereby securing the graft in the bone tunnel 28 .
- the ends 20 a may be rounded to prevent damage to the graft 34 , or sharpened to afford a better purchase on the graft.
- the spurs 22 - 24 tend to keep the graft 34 from being squeezed out around the edges of the device 10 .
- FIG. 5B it can be appreciated that when the flat plane of spikes 20 compresses the graft 34 downward (indicated by the reference arrow D; screw 36 removed for clarity) into the curved wall of the bone tunnel 28 , the graft has less room, and hence experiences greater pressure, at the edges of the flat plane.
- the graft 34 tends to shift laterally in response to the pressure, it will shift inward (indicated by the reference arrows 1 ) to an area of lower pressure, the area corresponding to a more central portion of the device.
- the central portion of the device 10 has a greater number of adjacent spikes 20 , and thus the graft 34 engages more spikes, and hence is better retained.
- One advantage of the embodiment described herein is that it securely affixes the graft to the bone, greatly reducing the chance of graft slippage.
- Another advantage of the embodiment described herein is that the device 10 and the screw 36 are disposed below the surface of the bone 30 in their installed positions. This produces a smooth profile that is less likely to cause the patient discomfort.
- the reference numeral 10 ′ refers to a soft tissue fixation device according to another embodiment of the invention.
- This embodiment incorporates several components of the embodiment of FIGS. 1 - 5 B, which are given the same reference numbers. According to FIG. 6, however, the spurs 22 - 24 of the foregoing embodiment are removed.

Abstract
Method and apparatus are described for a soft tissue fixation device for being biased between a soft tissue graft and an interference screw in a bone tunnel. The device has a contoured body portion having an inner surface and an outer surface. A plurality of spikes protrude from the outer surface of the body portion, the spikes extending perpendicular to the longitudinal axis of the body portion and parallel to each other. The distal ends of the spikes define a flat plane. A pin axially extends from the body portion for receiving a portion of the graft.
Description
- This application is a continuance of U.S. patent application Ser. No. 09/643010 filed Aug. 21, 2000.
- This disclosure relates generally to a device to be implanted during orthopedic surgery, and more particularly, to a soft tissue fixation device.
- Reconstructive surgery may be required after a patient injures a ligament, for example, the anterior cruciate ligament (ACL) of the knee joint. In ACL reconstruction, a replacement soft tissue or ligament (“graft” generically) is often used. The graft is affixed to a bone of the patient, such as the femur or tibia, to secure the graft while the graft attaches to the bone. In one method of affixing a graft to a bone, a tunnel is drilled through the bone, and a portion of the graft is inserted into the tunnel. A mechanical fastener, such as an interference screw and wedge, may then be inserted into the tunnel, thus holding the graft in the desired position.
- However, such prior art fasteners are prone to allow slippage of the graft (“graft slippage”) for a variety of reasons, resulting in undesirable loss of tension on the graft. Graft slippage is a very serious problem, impairing the efficacy of the reconstruction procedure, and in some cases even necessitating a second surgery to reposition and tension the graft. Moreover, during installation, sharp edges on the wedge or screw can cut or fray the graft, sometimes damaging the graft beyond usefulness. Also, it is sometimes difficult to judge the length of graft inserted into the bone tunnel, thus, too little of the graft may be engaged by the mechanical fastener, resulting in graft slippage.
- Therefore, what is needed is a device to securely affix a graft to a bone. Moreover, the device should be contoured to prevent damage to the graft. Finally, the device should allow a surgeon to readily estimate the length of graft inserted into the bone tunnel.
- Accordingly, an embodiment of the present invention provides for a soft tissue fixation device for being biased between a soft tissue graft and an interference screw in a bone tunnel. The device has a contoured body portion having an inner surface and an outer surface. A plurality of spikes protrude from the outer surface of the body portion, the spikes extending perpendicular to the longitudinal axis of the body portion and parallel to each other. The distal ends of the spikes define a flat plane. A pin axially extends from the body portion for receiving a portion of the graft.
- The device may be used in any procedure where a soft tissue or ligament graft needs to be directly affixed to a bone, such as knee ligament reconstruction, or other soft tissue reconstructions used in orthopedic surgery. One advantage of the embodiments described herein is they each securely affix the graft to the bone. Also, the embodiments are contoured to prevent damage to the graft. Finally, the embodiments allow a surgeon to readily estimate the length of graft inserted into the bone tunnel, thus reducing at least one cause of graft slippage.

- FIG. 10 is a cross sectional view of a soft tissue fixation device according to yet another embodiment of the present invention.
- Referring to FIGS.1-5B, the
reference numeral 10 refers to a soft tissue fixation device according to one embodiment of the present invention. Thedevice 10 has asemi-cylindrical body portion 12, which is substantially U-shaped in cross-section (FIG. 2). Thebody portion 12 has aninner surface 14 and anouter surface 16. - A series of channels, or grooves,18 are orthogonally disposed along the
inner surface 14 of thebody portion 12, for reasons to described. - A plurality of
spikes 20 protrude from theouter surface 16 of thebody portion 12. Thespikes 20 extend perpendicular to the longitudinal axis of thebody portion 12, and parallel to each other. As depicted, the spikes are arranged in longitudinal rows (FIG. 2), as well as lateral rows (FIG. 3). However, the disclosure contemplates staggered arrangements of thespikes 20 as well. - The
distal ends 20 a of thespikes 20 define a flat plane extending parallel to an imaginary plane extending between the uppermost surfaces 21 a-b of thebody portion 12. It is understood that in order to define the flat plane, the length of each of therespective spikes 20 is predetermined based upon the spike's relative location on the contouredouter surface 16 of thebody portion 12. The distal ends 20 a of thespikes 20 may be sharpened, as depicted, or rounded, for reasons to be described. - A pair of spurs22-24 project from a distal end of the
body portion 12 in an orientation parallel to thespikes 20. The spurs 22-24 extend past the flat plane defined by thespike ends 20 a, and terminate in chisel-shaped ends 22 a-24 a, respectively. - A
pin 26 extends axially from the opposite end of thebody portion 12, relative to the spurs 22-24. Thepin 26 is oriented parallel to the longitudinal axis of thebody portion 12, and has a substantially cylindrical shape. The length of thedevice 10 may be measured from the distal end of thepin 26 to the trailing edge of the spurs 22-24. - In operation, and referring to FIG. 4, a
bone tunnel 28 is bored in a patient's femur (hereinafter “bone”) 30 by any conventional means. It is understood that the bone tunnel alternatively could be bored in the patient'stibia 32. In the preferred method of use, thebone tunnel 28 is bored at a right angle relative to the longitudinal axis of thebone 30. Thus, once thedevice 10 is secured in thebone tunnel 28, the major component of any force that would tend to create graft slippage occurs at a right angle to the device, along the bone's longitudinal axis. The resulting force vector is thus considerably diminished, and thereby far less likely to result in graft slippage. However, the angle of thebone tunnel 28 is not a critical feature. Thebone tunnel 28 should be of a depth slightly greater than the length of the softtissue fixation device 10. - A
graft 34 to be affixed to thebone 30 is bent over itself to form aloop 34 a. Thegraft loop 34 a is placed over thepin 26, and the trailing ends of the graft threaded between the spurs 22-24. The spurs 22-24 help direct thegraft 34 under thespikes 20 to better engage the graft, and to prevent the edges of thedevice 10 from cutting the graft. Also, theouter surface 16 of the body portion is contoured to reduce the chance of the edges of the device cutting thegraft 34. - The
device 10, and hence thegraft 34, is inserted into thebone tunnel 28. It is understood that once theloop 34 a is placed over thepin 26, the length of thedevice 10 inserted in thebone tunnel 28 corresponds directly with the length ofgraft 34 inserted into the bone tunnel. This feature allows a surgeon to readily estimate the length of graft inserted into the bone tunnel. - Once installed, if the resulting tension on the
graft 34 is determined to be less than optimal for the reconstruction procedure, the graft anddevice 10 may be removed from thebone tunnel 28, and thegraft loop 34 a re-formed in a position corresponding to producing greater or lesser graft tension, as desired. Thus, the graft tension may be easily adjusted to produce an optimal graft tension, a significant advantage. - Once proper graft tension has been achieved, an
interference screw 36, having threads 36 a, is inserted in thebone tunnel 28 above thedevice 10. Thescrew 36 thus engages theinner surface 14 of thebody portion 12. Thescrew 36 may be rotated by any conventional means, such as with a driver adapted to engage a corresponding recessed socket of the screw. - Referring now to FIG. 5A, as the
screw 36 is rotated, it advances into thebone tunnel 28 via frictional engagement by the threads 36 a. The threads 36 a engage thegrooves 18 of thebody portion 12, and also the portion of thebone 30 defining thebone tunnel 28. - As the screw advances, it exerts forces upward into the
bone 30, and downward on thedevice 10, thereby firmly securing the device andgraft 34 in thebone tunnel 28. More specifically, in the upward direction, the force produced by thescrew 36 causes the threads 36 a to sink into thebone 30. Similarly, the downward force on thedevice 10 causes the spur ends 22 a-24 a to be driven deeply into thebone 30, thereby further securing the device in thebone tunnel 28. Once engaged with thebone 30, the spurs 22-24 prevent undesirable rotational movement by the device 10 (“rotational migration”) that would otherwise be caused by torsional forces associated with the screw's rotation. - The downward force exerted by the
screw 36 on thedevice 10 also causes thespikes 20 to engage and compress thegraft 34, thereby biasing the graft in thebone tunnel 28. As the flat plane ofspikes 20 engages thegraft 34, the graft is held at a number of contact points, the ends 20 a, thereby securing the graft in thebone tunnel 28. It can be appreciated that in some circumstances, the ends 20 a may be rounded to prevent damage to thegraft 34, or sharpened to afford a better purchase on the graft. - Several features of the device help keep the
graft 34 centralized under thedevice 10 while being compressed, and thus prevent graft damage and slippage. First, the spurs 22-24 tend to keep thegraft 34 from being squeezed out around the edges of thedevice 10. Second, referring now to FIG. 5B, it can be appreciated that when the flat plane ofspikes 20 compresses thegraft 34 downward (indicated by the reference arrow D; screw 36 removed for clarity) into the curved wall of thebone tunnel 28, the graft has less room, and hence experiences greater pressure, at the edges of the flat plane. Thus, if thegraft 34 tends to shift laterally in response to the pressure, it will shift inward (indicated by the reference arrows 1) to an area of lower pressure, the area corresponding to a more central portion of the device. The central portion of thedevice 10 has a greater number ofadjacent spikes 20, and thus thegraft 34 engages more spikes, and hence is better retained. - One advantage of the embodiment described herein is that it securely affixes the graft to the bone, greatly reducing the chance of graft slippage. Another advantage of the embodiment described herein is that the
device 10 and thescrew 36 are disposed below the surface of thebone 30 in their installed positions. This produces a smooth profile that is less likely to cause the patient discomfort. - Referring to FIG. 6, the
reference numeral 10′ refers to a soft tissue fixation device according to another embodiment of the invention. This embodiment incorporates several components of the embodiment of FIGS. 1-5B, which are given the same reference numbers. According to FIG. 6, however, the spurs 22-24 of the foregoing embodiment are removed. This embodiment has the advantage of retaining the graft in the bone tunnel without the device invasively engaging the bone, which may benefit certain types of patients. - Referring now to FIGS.7-9, the
reference numeral 40 refers to a soft tissue fixation device according to yet another embodiment of the present invention. Thedevice 40 has asemi-cylindrical body portion 42, which is substantially U-shaped in cross-section (FIG. 8). - The
body portion 42 has aninner surface 44 and anouter surface 46. A series ofgrooves 48 are orthogonally disposed along theinner surface 44 of thebody portion 42. An axial bore 49 runs the length of thebody portion 42, for reasons to be described. - A plurality of
spikes 50 protrude from theouter surface 46 of thebody portion 42, and extend perpendicular to the longitudinal axis of thebody portion 42 and parallel to each other. The distal ends 50 a of thespikes 50 define a flat plane extending parallel to an imaginary plane extending between the uppermost surfaces of thebody portion 42, as in the previous embodiments. The distal ends 50 a of thespikes 50 may be sharpened, as depicted, or rounded. - A pair of spurs52-54 project from a distal end of the
body portion 42 in an orientation parallel to thespikes 50. The spurs 52-54 extend past the flat plane defined by the spike ends 50 a, and terminate in chisel-shapedends 52 a-54 a, respectively. - A substantially cylindrical guide pin56 (FIG. 7) is provided for removable disposal in the axial bore 49 of the
body portion 42, as will be described. - In operation, a
bone tunnel 58 is bored in a patient'sbone 60 by any conventional means. In the preferred embodiment, thebone tunnel 58 is bored at a right angle relative to the longitudinal axis of thebone 60, and of a depth slightly greater than the length of thedevice 40. - The
guide pin 56 is installed in thebone tunnel 58 by any conventional means. As shown in FIG. 9, thepin 56 has been driven into thebone 60 to a depth greater than thebone tunnel 58. The guide pin is adapted to be slidably received by the axial bore 49 of thebody portion 42. - A
graft 64 to be affixed to thebone 60 is bent over itself to form a loop 64 a. The graft loop 64 a is placed over the distal end of theguide pin 56. The axial bore 49 of thedevice 40 receives theguide pin 56, and the trailing ends of thegraft 64 are threaded under the device and between the spurs 52-54. Thereafter, thedevice 40, and hence thegraft 64, are advanced into thebone tunnel 58, following theguide pin 56. - It is understood that the length of the
device 40 inserted in thebone tunnel 58 corresponds directly with the length ofgraft 64 inserted into the bone tunnel. If the tension on thegraft 64 is determined to be less than optimal for the reconstruction procedure, the graft anddevice 40 may be removed from thebone tunnel 58, and the graft loop 64 a re-formed in a position corresponding to producing greater or lesser graft tension, as desired. Thus, the graft tension may be easily adjusted, a significant advantage. - Once proper graft tension has been achieved, an
interference screw 66, havingthreads 66 a, is also inserted in thebone tunnel 58 above thedevice 40 to engage theinner surface 44 of thebody portion 42. As is best shown in FIG. 9, as thescrew 66 is rotated, it advances into thebone tunnel 58 via thethreads 66 a's frictional engagement with thegrooves 48 of thebody portion 42, and the portion of thebone 60 defining thebone tunnel 58. As thescrew 66 advances, it exerts forces upward into thebone 60 and downward on thedevice 40, firmly securing the device and compressing thegraft 64 in thebone tunnel 58. - The
device 40 enjoys the advantages of the embodiment of FIGS. 1-5B, and also has the benefit of allowing precise placement of the device via the guide pin. Moreover, this embodiment uses both the guide pin and spurs to prevent undesirable rotational migration of the device during tightening of the screw. - Referring now to FIG. 10,
reference numeral 70 refers to a soft tissue fixation device according to yet another embodiment of the invention. This embodiment incorporates the features of either the embodiment of FIGS. 1-5B, or of FIGS. 7-9. According to FIG. 10, however, the spurs of the foregoing embodiments are modified. - The device70 (FIG. 10) has a
semi-cylindrical body portion 72, which is substantially U-shaped in cross-section. Thebody portion 72 has aninner surface 74 and anouter surface 76. Although not depicted, a series of grooves may be orthogonally disposed along theinner surface 74 of thebody portion 72. - A plurality of
spikes 80 protrude from theouter surface 76 of thebody portion 72. As depicted, thespikes 80 extend perpendicular to the longitudinal axis of thebody portion 72, and parallel to each other. The distal ends 80 a of thespikes 80 define a flat plane extending parallel to an imaginary plane extending between the uppermost surfaces of thebody portion 72. The distal ends 80 a of thespikes 80 may be sharpened, as depicted, or rounded. Though not depicted, it is understood that this embodiment has features for retaining a graft loop (“retaining means”), such as a hook, or a suture, or an axially extending integrated pin (e.g., FIG. 1), or a removable guide pin and axial body portion bore (FIG. 7). It is understood that in operation, thedevice 70 functions in substantially the same manner as the above-described embodiments. - A pair of spurs82-84 project from a distal end of the
body portion 72 in an orientation parallel to thespikes 80. The spurs 82-84 extend past the flat plane defined by the spike ends 80 a, and terminate in chisel shaped ends 82 a-84 a, respectively. The spurs 82-84 are connected by awall 86, which provides reinforcement against lateral movement by the spurs. Thewall 86 stabilizes the spurs, allowing greater penetration of the spur ends 82 a-84 a into the bone, and thereby further securing thedevice 70 in the bone tunnel. - It is understood that all spatial references, such as front, rear, upward, and downward, are only for the purposes of explanation of the drawings. This disclosure shows and describes illustrative embodiments, however, the disclosure contemplates a wide range of modifications, changes, and substitutions. For example, the invention encompasses using radial spikes following the contour of the body portion rather than the parallel spikes of the above-described embodiments. Similarly, the flat plane of spike ends may be created by parallel spikes of a uniform length extending from a flattened portion of the body portion. Likewise, variations may employ only some features of the embodiments, such as the
spur-less device 10′ of FIG. 6, without departing from the scope of the underlying invention. Accordingly, any appropriate construction of the appended claims will reflect the broad scope of the underlying invention.
