Spine Patient Outcomes Research Trial (SPORT) - Intervertebral Disc Herniation

The surgeon will leave the nerve root freely mobile and undamaged following the procedure. During the procedure, the surgeon may consider using loop magnification or a microscope. The surgical incision will be midline and, after reflecting the paraspinous muscles, the interlaminar level will be identified and entered. The nerve root will be clearly identified and mobilized and then gently retracted to prepare for the discectomy. Removal of the medial border of the superior facet may, in some cases, be necessary in order to have a clear view of the lateral border of the involved nerve root. Following the clear view of the nerve root and mobilization, the IDH will be approached by making a small annular incision if necessary, the fragment of disc will then be removed (i.e., limited disc excision). A search of the canal will follow removal of the fragment, along with probing of the intervertebral-foramen for residual disc or bony pathology.
