Commentary on: The Effect of L5-S1 Fusion on Global Spine Motion: A Range of Motion Analysis Comparing 2-Level TDR versus Hybrid at L4-S1 in 235 Patients - Abstract
The original goal of this paper was to explore the consequences of L5-S1 fusion on lumbar spine motion and identify the consequences of a hybrid construct, versus a two-level disc replacement, necessitated in some cases, when only one TDR implant was reimbursed.
