[0053] FIG. 5 illustrates a top perspective view of an embodiment of the first module 510. The first module may be in the form of a tray 511 having a generally rectangular shape, although other shapes may be desirable depending on functional, economic, aesthetic or other reasons. The tray 511 includes a first well 512 and a second well 513. The first well 512 includes a fastener housing 530 and the second well 513 includes a bone plate 540.

[0054] FIG. 6 illustrates a top perspective view of the fastener housing 630. The fastener housing 630 includes a fastener length gauge 631 configured and labeled by a size label 631a for measuring incremental lengths of a plurality of fasteners. The incremental lengths may range, for example, between 10 mm and 30 mm by 2 mm increments. As illustrated in more detail in FIG. 6C, the fastener length gauge 631 has a channel 631b and a seat 631c. Using fastener length gauge 631, the surgeon may quickly confirm the length of a selected fastener prior to implantation of the fastener into the patient, and ensure that the fastener is of sufficient length to properly engage bone, but not so long as to protrude too far from the bone and into soft tissue.

[0055] FIGS. 6 and 6A illustrate a perspective and top view of the fastener housing 630 wherein the fastener housing 630 includes a plurality of first fastener receptacles 632 to house a first plurality of fasteners and a plurality of second fastener receptacles 633 to house a second plurality of fasteners. Each of the first and second receptacles 632, 633 is sized and shaped to loosely retain a first plurality of fasteners and a second plurality of fasteners, respectively.

[0056] The fastener housing 630 may be prepared using injection-molding to form a first cavity 634 extending from the left sidewall 639a to a molded dividing wall 639b, which is located directly underneath the plurality of first fastener receptacles 632. The fastener housing 630 may further include a second cavity 635 separated from the first cavity by the molded dividing wall 639b, which is located directly underneath the plurality of second fastener receptacles 633. The first cavity 634 and second cavity 635 are surrounded by the molded walls of the fastener housing 630 on three sides with the fourth side open so that the shafts of the fasteners are visible.

[0057] As illustrated in FIGS. 6B and 6D, the fastener housing 630 additionally includes a plurality of protrusions 637 that extend upwards and away from the top of the fastener housing 630. The first cavity 634 and the second cavity 635 each include a plurality of stairs 636 that extend downward from the top of the fastener housing, and a plurality of concave depressions 638 that sit on the top surface of the stairs 636. In one embodiment, the heads of the fasteners sit atop the plurality of protrusions 637 while a small portion of the shaft of the fasteners sit within the plurality of concave depressions 638. The stairs 636 cause the fasteners to sit within the fastener housing 630 in a staggered configuration. The plurality of protrusions 637, plurality of stairs 636 and plurality of concave depressions 638 act in combination to prevent fastener angulation or jamming during transit and handling.

[0058] The first plurality of fasteners may be arranged in the first fastener receptacle 632 in a plurality of groupings of 7 or fewer fasteners and the second plurality of fasteners may be arranged in the second fastener receptacle 633 in a plurality of groupings of 4 or fewer fasteners. Each grouping corresponds to a particular one of a number of distinct fastener lengths. As shown in FIG. 6, receptacles 632 and receptacles 633 are arranged in groupings, such that each grouping may include up to 4 fasteners of the same shaft length.

[0059] When the kit is opened, the user may easily grasp the exposed end of each fastener and remove it from fastener housing 630. Alternately, the user may pick each fastener from the fastener housing 630 using a suitable drive instrument. Since each single-use kit may include only the number of fasteners required for the particular surgical indication, with a few extra, a number of first fastener receptacles 632 and second fastener receptacles 633 may be empty.

[0060] FIGS. 7 and 7A illustrate the cutout portions included in sterile tray 700 in which the first module 710 and second module 720 are housed.
