A surgical tool comprising:
- a humeral head cut guide configured to fit within a rotator interval of a subject in need of shoulder arthroplasty;
- the cut guide further comprising:
- a top surface, a bottom surface, a front surface, a back surface, and at least two sides, each of the two sides defining a flat surface extending from the back surface to the front surface and from the top surface to the bottom surface;
- at least two nonconverging pin holes, each pin hole extending transversely from an entry point located on a side of the cut guide to an exit point on the front surface of the cut guide;
- and
- a receiving portion configured to permit reversible attachment of the cut guide to an attachment arm assembly and detachment of the cut guide from the attachment arm assembly, the receiving portion terminating in a threaded opening that extends partially into the cut guide and is configured to further secure the cut guide to the attachment arm assembly.
A method for total shoulder arthroplasty using a surgical tool, the method comprising opening of a rotator interval and humeral head osteotomy through the rotator interval, the surgical tool comprising:
- a humeral head cut guide configured to fit within the rotator interval of a subject in need of shoulder arthroplasty;
- the cut guide further comprising:
- a top surface, a bottom surface, a front surface, a back surface, and at least two sides, each of the two sides defining a flat surface extending from the back surface to the front surface and from the top surface to the bottom surface;
- at least two nonconverging pin holes, each pin hole extending transversely from an entry point located on a side of the cut guide to an exit point on the front surface of the cut guide;
- and
- a receiving portion configured to permit reversible attachment of the cut guide to an attachment arm assembly and detachment of the cut guide from the attachment arm assembly, the receiving portion terminating in a threaded opening that extends partially into the cut guide and is configured to further secure the cut guide to the attachment arm assembly.
