US 2024/0188997 A1 · CERVICAL LAMINOPLASTY INSTRUMENTS AND PROCEDURES

Abstract

Devices and methods for performing a cervical laminoplasty procedure on a patient. An exemplary device includes a primary instrument having a proximal portion and a distal portion, a secondary instrument having a distal portion, and an implant plate assembly having an implant plate and an implant post. The distal portion of the primary instrument can be configured to engage the implant post of the implant plate assembly. A lateral side of the implant plate can engage a lateral portion of a lamina of a vertebra, and a medial side of the implant plate can engage a medial portion of a lamina of a vertebra. The implant plate can be bent and a corresponding adjustment in an angle between the lateral and medial portions of the lamina can be achieved.

Claims18

Dependent claims

A cervical laminoplasty system, comprising:

a primary instrument having a proximal portion and a distal portion;
an implant plate having a medial side and a lateral side;
one or more medial bone screws configured to secure a medial side of the implant plate to a medial portion of a lamina of a vertebra;
and
one or more lateral bone screws configured to secure a lateral side of the implant plate to a lateral portion of a lamina of a vertebra.

2 more elements

A method of performing a cervical laminoplasty procedure, the method comprising:

creating a partial cut in a first lamina of a vertebra of a patient;
attaching an implant plate with the vertebra of the patient, wherein a lateral side of the plate is attached with a lateral portion of the first lamina of the vertebra, and wherein a medial side of the plate is attached with a medial portion of the first lamina of the vertebra;
creating a full cut in a second lamina of the vertebra of the patient;
engaging a primary instrument of a cervical laminoplasty system with the implant plate;
and
moving the first instrument of the cervical laminoplasty system relative to the patient to form a bend in the implant plate, the bend disposed between the lateral side of the implant plate and the medial side of the implant plate.
