Fig. 7From: Determining a relative total lumbar range of motion to alleviate adjacent segment degeneration after transforaminal lumbar interbody fusion: a finite element analysisDetermination of a relative total lumbar ROM. (A) The total L1-S1 ROM with IDP constraints. (B) The total L1-S1 ROM with FJF constraints. (C) The relative total L1-S1 ROM in the TLIF model. ROM: range of motion; IDP: intradiscal pressure; FJF: facet joint force; TLIF: transforaminal lumbar interbody fusionBack to article page
