FIGS. 5-9 schematically illustrate an exemplary method for filling a bone void. The exemplary method may utilize a bone void plug such as any of those described above and illustrated inFIGS. 1A , 1B, 1C, 1D, 2, 3A, 3B, and 4. For example, any of the exemplary bone void plugs 10, 110, 210 may be used to inhibit displacement of a bone void filler out of a bone void formed in the bone. - In one non-limiting embodiment, the method illustrated by
FIGS. 5-9 is performed as part of a revision surgery to reconstruct an ACL footprint in response to a failed original repair. In another embodiment, the method repairs damaged bone. The method could also have many other applications. Furthermore, although specific steps are illustrated inFIGS. 5-9 , the method could include greater or fewer steps which may be performed in any order within the scope of this disclosure. - As illustrated in
FIG. 5 , the method may begin by inserting aguide pin 50 into abone 52. Thebone 52 could be a femur or any other bone or tissue. A surgeon will be able to select an appropriate positioning and/or placement of theguide pin 50 and could use fluoroscopic guidance and/or a targeting guide to achieve proper placement. - Once the
guide pin 50 has been positioned, a cannulateddrill bit 54 may be placed over theguide pin 50 to ream abone void 56 into thebone 52. This is shown inFIG. 6 . The size of theguide pin 50 and the cannulateddrill bit 54 may vary depending upon the size of the patient and the amount of bone that needs removed, among other criteria. Once thebone void 56 is created, the cannulateddrill bit 54 andguide pin 50 may be removed from thebone 52. - Alternatively, the
bone void 56 may be formed without using a guide pin by simply reaming thebone 52 with a drill bit or other tool. In yet another embodiment, thebone void 56 is a preexisting defect in thebone 52 such that drilling and reaming operations are not necessary to form thebone void 56. Thebone void 56 may extend between anopening 60 and afloor 61, in one embodiment. - Next, as illustrated by
FIG. 7 , a bonevoid plug bone void 56. In one embodiment, the bonevoid plug bone void 56 by hand or with a tool. Alternatively, the bonevoid plug bone void 56. - In one embodiment, the bone
void plug opening 60 of thebone void 56. Theopening 60 may be located at a junction between anexterior surface 62 of thebone 52 and thebone void 56. Theproximal face void plug exterior surface 62. Theplug body bone void 56 in a direction toward thefloor 61 and contact aperipheral wall 64 of thebone void 56. - In one embodiment, if the bone void plug 210 of
FIG. 4 is used, aflexible member 86 may be fixated to the bone void plug 210 prior to positioning the bone void plug 210 into the opening 60 (seeFIG. 4 ). The fixation features 88 grip theflexible member 86 to temporarily fixate it relative to the bone void plug 210. - Referring to
FIG. 8 , adelivery tool 66 may be inserted through theport 20, 220 of the bonevoid plug opening delivery tool 66 may include achamber 69 that carries a bonevoid filler 70 for filling thebone void 56. In one embodiment, thedelivery tool 66 includes aneedle 68 that is insertable through theport 20, 220, and optionally through a septum (seefeature 26 ofFIG. 2 ), for delivering the bonevoid filler 70 into the recessedopening bone void 56. Theport 20, 220 may prevent leakage of materials or substances back through the bonevoid plug delivery tool 66. - In one embodiment, again assuming the bone void plug 210 of
FIG. 4 is employed, the bonevoid filler 70 is injected into thebone void 56 and may flow around the flexible member 86 (seeFIG. 4 ). Once the bonevoid filler 70 cures, theflexible member 86 is substantially fixated to the bone void plug 210. - Finally, as shown in
FIG. 9 , all or portions of thebone void 56 may be backfilled with the bonevoid filler 70. The bonevoid filler 70 may include a variety of substances for plugging thebone void 56. Non-limiting examples of suitable bone void fillers include calcium phosphate bone cements, biologics, or any other filler materials. The bonevoid filler 70 may also be either injectable or non-injectable bone filler materials. - The bone
void plug bone void 56 and allows the bonevoid filler 70 to cure, set, harden, etc. inside thebone void 56 without risk of displacement from within thebone void 56. In other words, the bonevoid plug void filler 70 out of thebone void 56 in a direction Z prior to its hardening, setting, curing, etc. - The bone
void plug void filler 70 has cured. Additional revision repairs may then be performed. Once removed, the bonevoid plug void filler 70, but generally leaves a relatively flat surface for eventual or immediate surgical need. -
