A system comprising:
- a first guide block including a first through hole, a second through hole, a third through hole, and a fourth through hole;
- a first guidewire configured to be positioned through the first through hole;
- a second guidewire configured to be positioned through the second through hole;
- a third guidewire configured to be positioned through the third through hole, wherein the third guidewire includes a first portion having a first diameter and a second portion having a second diameter that is less than the first diameter;
- a fourth guidewire configured to be positioned through the fourth through hole, wherein the fourth guidewire includes a first portion having a first diameter and a second portion having a second diameter that is less than the first diameter;
- a first hard stop feature configured to be positioned over the third guidewire, wherein the first hard stop feature has an inner diameter greater than the second diameter of the third guidewire but less than the first diameter of the third guidewire;
- a second hard stop feature configured to be positioned over the fourth guidewire, wherein the second hard stop feature has an inner diameter greater than the second diameter of the fourth guidewire but less than the first diameter of the fourth guidewire;
- a second guide block including a first through hole configured to receive the first guidewire, a second through hole configured to receive the second guidewire, a third through hole configured to receive the third guidewire, and a fourth through hole configured to receive the fourth guidewire, wherein the second guide block is configured to contact the first hard stop feature and the second hard stop feature;
- a first reamer configured to be positioned over the first guidewire and through the first through hole of the second guide block, wherein the first reamer includes a third hard stop feature having a diameter greater than a diameter of the first through hole of the second guide block;
- and
- a second reamer configured to be positioned over the second guidewire and through the second through hole of the second guide block, wherein the second reamer includes a fourth hard stop feature having a diameter greater than a diameter of the second through hole of the second guide block.

A system comprising:
- a handle;
- a guide base coupled to the handle;
- a guidewire hole guide removably coupled to the guide base;
- a first guidewire having a first end and a second end opposite the first end, wherein the first end of the first guidewire is configured to be positioned through a first through hole in the guidewire hole guide, wherein the first guidewire includes a first hard stop feature positioned between the first end and the second end of the first guidewire, wherein the first hard stop feature has a diameter greater than a diameter of the first through hole, and wherein the first guidewire includes a reduced diameter portion between the first hard stop feature and the first end of the first guidewire;
- a second guidewire having a first end and a second end opposite the first end, wherein the first end of the second guidewire is configured to be positioned through a second through hole in the guidewire hole guide, wherein the second guidewire includes a second hard stop feature positioned between the first end and the second end of the second guidewire, wherein the second hard stop feature has a diameter greater than a diameter of the second through hole, and wherein the second guidewire includes a reduced diameter portion between the second hard stop feature and the second end of the second guidewire;
- a first reamer having a first end and a second end opposite the first end, wherein the first end of the first reamer is configured to be positioned over the first guidewire and through the first through hole of the guidewire hole guide, and wherein the first reamer includes a third hard stop feature adjacent the second end of the first reamer;
- and
- a second reamer having a first end and a second end opposite the first end, wherein the first end of the second reamer is configured to be positioned over the second guidewire and through the second through hole of the guidewire hole guide, and wherein the second reamer includes a fourth hard stop feature adjacent the second end of the second reamer.
