    Description

    CROSS-REFERENCE TO RELATED APPLICATION



    [0001] The present application claims the benefit of the filing date of U.S. Provisional Patent Application No. 62/478,963, filed on March 30, 2017.

    FIELD OF THE INVENTION



    [0002] The present invention relates to an implant with suture pockets having suture holes.

    BACKGROUND OF THE INVENTION



    [0003] Orthopedic surgeries may require implants to be attached to soft tissue and/or tuberosities by sutures. By way of example but not limitation, a fracture occurring in the proximal region of the humerus may require a shoulder prosthesis with multiple suture holes by which the prosthesis can be attached to the body. Attaching sutures to an implant requires a surgeon to successfully insert suture needles through these suture holes and therefore requires considerable time, skill and effort. Manipulation of suture needles through the narrow suture holes which are often located in tight, inaccessible locations can be challenging especially during surgery. A surgeon must precisely place a needle tip through the narrow suture hole for successful needle insertion, and repeat this step many times over to complete implant attachment to body.

    [0004] Suture holes on implants such as a shoulder prosthesis are generally located on a fin or a flange to allow for soft tissue attachment. A vertical array of circular suture holes is provided on a fin to maximize visibility. Suture hole openings are generally flush with the fin surface. Therefore, suturing these holes will require precise location of the needle tip into the circular opening. If a surgeon misses the circular opening and contacts the needle tip to the fin surface, the surgeon must attempt again to successfully target the circular opening. Furthermore, a curved suture needle is generally used in such procedures and makes targeting the narrow suture hole openings more challenging and time-consuming for a surgeon. Furthermore, fins or flanges containing suture holes generally extend from the implant body into soft tissue or bone and will consequently require additional effort in positioning, and implanting the prosthesis.

    [0005] Therefore, there exists a need for improved suture passages and a method for attaching sutures to an implant having the same.

    [0006] US 2006/0189987 A1 discloses a humeral fracture fixation system including a nail-plate fixation device having a plate-like head portion, an intramedullary nail portion, and a bent neck portion therebetween which creates an angle between the plate and nail portions. The head portion includes locking holes for receiving fixed-angle bone support elements, and K-wire alignment holes. The front of the head portion includes suture holes while presenting a smooth profile.

    [0007] US 2011/0130840 A1 discloses an attachment device that secures soft tissue to an orthopedic prosthetic implant or bone. The attachment device includes a receptor surface, an attachment plate with an attachment surface, and fasteners. The receptor surface can be formed on the implant or on a separate receptor plate. The receptor surface accepts the soft tissue and/or a bony structure, the attachment plate at least partially covers the receptor surface, and the fasteners secure them together to compress and hold in place the soft tissue and/or a bony structure.

    [0008] WO /012376 A1 discloses an implant for repairing a defect in a bone structure. The implant comprises a U-shaped suture channel which extends along a centre line through the implant and which has first and second end openings opposite each other opening to a common face. In an aspect the suture channel has a middle portion with a first size in cross section with respect to the centre line of the suture channel and at least one of the end openings has a second size in cross section larger than the first size. In another aspect the first and second end openings of the U-shaped suture channel are formed by a first hole and a second hole extending into the implant from the common face in respective first and second directions extending into the implant from the common face, the first hole and the second hole communicating within the implant and providing the U-shaped suture channel through the implant, for guiding curved suture needles through the suture channel.

    BRIEF SUMMARY OF THE INVENTION



    [0009] The present invention is defined by the features of the independent claim. Preferred embodiments are given in the dependent claims. Successful suture insertion into a suture hole of the present invention is not limited to placing a suture needle tip in the opening of a suture hole, instead a surgeon may insert a suture by placing a suture needle tip on a sidewall and then slide the needle into the suture hole. The sidewall extends beyond the suture hole and allows a suture needle tip to be guided into the suture hole.

    DETAILED DESCRIPTION



    [0011] Referring to FIG. 1, there is shown a partial perspective view of humeral stem 100 having a plurality of suture holes 110 according to one embodiment of the present invention. A curved suture needle 112 with a tip 114 disposed within suture hole 110 is also shown. Suture holes 110 are disposed within a first pocket 128 and a second pocket 132. As best seen in FIG. 1, suture pockets 128 and 132 are located within the peripheral contours of humeral stem 100 forming substantially contiguous peripheral walls to facilitate soft tissue and bone manipulation during implantation of humeral stem 100.

    [0012] FIGS. 2A and 2B show a cross section of suture hole 110 at line A--A. Suture hole 110 includes a first opening 116 and a second opening 118. A first sidewall 122 is made of three segments: a first pocket segment 126 in first pocket 128, a first sidewall segment 124 along suture hole 110, and a second pocket segment 130 in second pocket 132. As best seen in FIG. 2B, all three segments (124, 126, 130) of first sidewall 122 form a smooth, continuous wall free from obstructions. Consequently, needle tip 114 may be placed along first pocket segment 126 and slid smoothly across first sidewall 122 until needle tip 114 enters suture hole 110. Alternatively, needle tip 114 may be placed along second pocket segment 130 and slide smoothly in the opposite direction to enter suture hole 110 through second opening 118. Hence, first pocket segment 126 and second pocket segment 130 function as guide tracks to successfully guide a suture needle tip 114 into suture hole 110.

    [0013] A second sidewall 120 is located opposite to first sidewall segment 124 and extends from first opening 116 to second opening 118 to define a first length D1. Second sidewall 120 may be chamfered at first opening 116 and at second opening 118, to facilitate suture needle entry and exit respectively.

    [0014] FIG. 2C is a side elevation view along line B--B showing first pocket 128 and suture hole 110. Suture hole 110 is oblong shaped and includes a curved upper surface 134 and a curved lower surface 136 joining first sidewall segment 124 and second sidewall 120. The oblong shape and narrow shoulder area region 138 between suture holes 110 are configured to maximize insertion location points for needle tip 114. Suture needle tip 114 may be placed either directly into opening 116 or placed at any point along first pocket segment 126 and slid into opening 116 to attach a suture to humeral stem 100. Hatched region 142 shown in FIG. 2C represents all first contact locations for suture needle tip 114 whereby successful insertion of suture needle 112 may be achieved through first opening 116. Similarly, suture needle tip may also be placed at any point along second pocket segment 130, and slid into suture hole 110 through second opening 118.

    [0015] FIG. 3 shows an alternate arrangement of first sidewall 122', which does not form part of the present invention. In this embodiment, first pocket segment 126' and second pocket segment 130' are deflected away from second sidewall 120 consequently resulting in enlarged first and second pockets 128' and 132'. These enlarged pockets provide for a wider insertion angle for tip 114, whereby needle tip 114 can be placed on first pocket segment 126' and slid readily into suture hole 110. Although first pocket segment 126' and second pocket segment 130' are angled with respect to first sidewall segment 124, first sidewall 122' provides a contiguous, uninterrupted surface that allows suture needle tip 114 to smoothly slide along first pocket segment 126' or second pocket segment 130' and into suture hole 110. First and second pocket segments 126', 130' may also be configured to deflect toward the second side wall 120. Any of first pocket segment 126', first sidewall segment 124, and second pocket segment 130' may be curved and configured for specific suture needle shapes and suturing techniques.

    [0016] Referring now to FIG. 4, there is shown curved suture needle 112 disposed within suture hole 110 such that needle tip 114 is outside suture hole 110. A chord length D2 of curved suture needle 112 is defined by the intersection of a plane 133 containing second sidewall 120. As best seen in FIG. 3, D2 is larger than D1. Consequently, suture needle 112 may readily pass through suture hole 110 without contacting second sidewall 120. The smooth, continuous first sidewall allows needle tip 114 to be placed on first pocket segment 126, slid into suture hole 110 and finally exit second opening 118 to complete passage of suture needle 122 through suture hole 110, without contacting second sidewall 120 as shown in FIG. 4.

    [0017] FIG. 5A is a perspective view of humeral stem 100 showing a first arrangement 142 and a second arrangement 144 of suture holes 110 of the present invention. As shown in partial perspective FIG. 5B, an axis L1 running through suture hole 110 centers is offset to an axis L2 of the humeral stem 100 and proximal face 140. This offset arrangement provides a larger surface area for suture hole locations and consequently maximizes the number of suture holes 110 and suture hole area available for suture attachment.

    [0018] Referring now to FIGS. 6A and 6B, there is shown a top view of proximal face 140 and a side elevation view of the proximal end of humeral stem 100 respectively. Proximal face 140 of humeral stem 100 is provided with multiple surfaces 146, 148, 150, 152, and 154. The multiple surfaces and positive slope as indicated by an axis L3 in FIG. 6B provide stability to a tuberosity during needle insertion and wrapping of sutures around tuberosity post suture insertion. The edge of humeral stem 100 is designed to be substantially squared off (not round), preventing tuberosity rotation at the corners. This design feature also provides stability for short term fixation of the tuberosity prior to bone healing. An angle 158 measured between a centerline of the humeral stem 100 and edge 135 is configured to be between 55° and 60°. This angular range for angle 158 is provided so that a surgeon may align suture pockets 128, 132 with respect to the bicipital groove by visually examining the position of edges 135 during suture insertion and wrapping of tuberosities.

    [0019] Also disclosed is a method for attaching a suture to an implant having suture holes disposed within suture pockets. This method does not form part of the present invention. Referring now to FIGS. 7A-7C, there is shown a method of inserting curved suture needle 112 to humeral stem 100 through suture hole 110. Suture needle tip 114 is placed anywhere along first pocket segment 126. Alternatively, as illustrated in FIG. 2C, suture needle tip 114 may be directly placed into first opening 116 as indicated by the hatched region 142. After contacting surgical needle tip 114 on first pocket segment 126, a surgeon may slide needle 112 in the direction of arrow 160 shown in FIG. 7A. Needle tip 114 is guided along first pocket segment 126 and into suture hole 110 as shown in FIG. 7B. As more fully explained above, seamless connection between first pocket segment 126 and first sidewall segment 124 ensures that needle tip 114 readily slides into suture hole 110. Suture needle 112 may now be rotated as indicated by arrow 162 to slide needle tip 114 from first opening 116 to second opening 118, and finally to exit suture hole 110 as shown in FIG. 7C. Thus a surgeon can readily insert suture needle 112 into suture hole 110 by placing suture needle tip 114 anywhere along the hatched region shown in FIG. 2C, and thereby minimize the effort to successfully attach sutures to an implant because successful insertion is not limited to accurately placing needle tip 114 (first point of contact) in suture hole openings. Alternatively, suture needle tip 114 may be placed along second pocket segment and slid into suture hole 110 through second opening 118. Uniform suture hole geometry will allow a surgeon to utilize a single suture insertion technique for attaching sutures to all suture holes.

    [0020] While a humeral stem of a shoulder prosthesis is described in these embodiments, suture holes disclosed herein may be used with any other prostheses including, but not limited to, spinal implants with suture holes and suture anchors. Other prostheses utilizing suture holes of the present invention may have different suture holes configurations and arrangements. Suture holes may also be configured to carry multiple suture threads in a single hole. Although suture hole slots described here are oblong shaped, other shapes including, but not limited, to circular, square, rectangular, triangular, etc., may also be used.

    [0021] Whereas the first sidewall 122 of the invention has three segments, other examples, which do not form part of the present invention, may only have a first sidewall with only two segments: a first pocket segment 126 and a first sidewall segment 124, i.e., with only a first pocket and no second pocket. A curved suture needle 112 is generally described here, however, the suture holes of the present invention may be used with any of, but not limited to, a straight needle, a half-curved needle, a curved needle and a compound curved needle. While the first sidewall and the second sidewall are generally shown to be linear here, other embodiments may have curved first and second sidewalls.

    [0022] Implants containing suture holes of the present invention may be made from any of, but not limited to, PEEK, polymers and titanium and/or titanium alloys, stainless steel, and cobalt chrome. Additive manufacturing techniques such as 3D printing may be used to fabricate implants with suture holes of the present invention.

    [0023] Furthermore, although the invention disclosed herein has been described with reference to particular features, it is to be understood that these features are merely illustrative of the principles and applications of the present invention. It is therefore to be understood that numerous modifications, including changes in the sizes of the various features described herein, may be made to the illustrative embodiments and that other arrangements may be devised without departing from the scope of the present invention.
