T1-T2 disc herniation: Report of four cases and review of the literature

Background:

Symptomatic T1–T2 disc herniations are rare and, in most cases, are located posterolaterally. Posterior approaches may utilize transfacet pedicle-sparing techniques, while the less frequent central/anterolateral discs may warrant anterior surgery.

Case Description:

Here, we reviewed four cases of symptomatic T1–T2 disc herniations; two patients were paraparetic due to central discs and underwent anterior surgery utilizing a cage construct. The latter two cases had posterolateral discs contributing to a Brown-Sequard syndrome and radiculopathy, respectively; one patient required a transfacet pedicle-sparing procedure, while the second case was managed conservatively. All surgically treated patients recovered fully.

Conclusions:

We reviewed 4 cervical T1–T2 disc herniations; two central/anterolateral lesions warranting anterior surgical approaches/cages, and 2 lateral discs treated with a posterolateral transfacet, pedicle-sparing procedure and no surgery respectively. Follow-up magnetic resonance studies documented full resolution for the patient with radiculopathy and a posterolateral disc.
