Abstract
Objective : To compare the clinical outcomes and biomechanical effects of total disc replacement (TDR) and posterior cervical
foraminotomy (PCF) and to propose relative inclusion criteria.
Methods : Thirty-five patients who underwent surgery between 2006 and 2008 were included. All patients had single-level
disease and only radiculopathy. The overall sagittal balance and angle and height of a functional segmental unit (FSU; upper and
lower vertebral body of the operative lesion) were assessed by preoperative and follow-up radiographs. C2-7 range of motion (ROM),
FSU, and the adjacent segment were also checked.
Results : The clinical outcome of TDR (group A) was tended to be superior to that of PCF (group B) without statistical significance.
In the group A, preoperative and postoperative upper adjacent segment level motion values were 8.6±2.3 and 8.4±2.0, and lower
level motion values were 8.4±2.2 and 8.3±1.9. Preoperative and postoperative FSU heights were 37.0±2.1 and 37.1±1.8. In the group
B, upper level adjacent segment motion values were 8.1±2.6 and 8.2±2.8, and lower level motion values were 6.5±3.3 and 6.3±3.1.
FSU heights were 37.1±2.0 and 36.2±1.8. The postoperative FSU motion and height changes were significant (p<0.05). The patient’s
satisfaction rates for surgery were 88.2% in group A and 88.8% in group B.
Conclusion : TDR and PCF have favorable outcomes in patients with unilateral soft disc herniation. However, patients have
different biomechanical backgrounds, so the patient’s biomechanical characteristics and economic status should be understood
and treated using the optimal procedure.
