Posterolateral instrumentation treatment system and methods

A kit of components for assembling an implantable device, the kit comprising:

• a bone rod, wherein the bone rod has an interior chamber that extends along at least a portion of the length of the bone rod, and wherein the bone rod has a plurality of fenestrations extending from the interior chamber to an external surface of the bone rod;
• and
• a flexible tubing that is configured to be removably coupled to the bone rod, wherein the flexible tubing is configured to be in fluid communication with the interior chamber of the bone rod when removably coupled to the bone rod;
• and
• a connector coupled to the flexible tubing, wherein the flexible tubing is configured to be removably coupled to the bone rod via the connector, thereby securing the connector to the bone rod unless subjected to a removal force that exceeds a first characteristic force, wherein the removable connector is configured to selectively connect to the bone rod via at least one of an annular ridge, one or more lips, an adhesive, one or more clips, one or more clamps, sutures, or press-fitting such that the first characteristic force is a non-zero force, and wherein the first characteristic force is less than a specified fraction of a second characteristic force sufficient to separate the connector from the flexible tubing.

A method comprising:

• during a surgical intervention, fixing two or more bone screws into respective portions of bone of a patient;
• during the surgical intervention, fixing a bone rod to the two or more bone screws, wherein the bone rod has an interior chamber that extends along at least a portion of the length of the bone rod, and wherein the bone rod has a plurality of fenestrations extending from the interior chamber to an external surface of the bone rod;
• during the surgical intervention, coupling a flexible tubing to the bone rod such that the flexible tubing is in fluid communication with the interior chamber of the bone rod, wherein a connector is coupled to the flexible tubing, wherein coupling the flexible tubing to the bone rod comprises removably coupling the flexible tubing to the bone rod via the connector such that the connector is secured to the bone rod;
• and
• subsequent to an end of the surgical intervention, removing the flexible tubing from the patient by applying, to the flexible tubing, a force that is greater than a first characteristic force sufficient to uncouple the connector from the bone rod and that is less than a second characteristic force sufficient to separate the connector from the flexible tubing, thereby uncoupling the connector from the bone rod, wherein removably coupling the flexible tubing to the bone rod via the connector comprises using an adhesive, a suture, a clip, or a clamp to secure the connector to the bone rod, and wherein a portion of the adhesive, suture, clip, or clamp are at least one of resorbable or composed of a material that weakens over time such that a force sufficient to uncouple the connector from the bone rod decreases over time after coupling the flexible tubing to the bone rod via the connector.
