Assessing the Usefulness of Motor-Evoked Potential Changes in Disc Height Determination in Patients with Degenerative Disc Diseases Treated with Interbody Fusion.

Aim: To evaluate the effectiveness of improved motor-evoked potentials (MEPs) in treatment of degenerative disc diseases using the transforaminal lumbar interbody fusion (TLIF) technique.

Material And Methods: Data of one hundred and eleven patients who underwent TLIF were retrospectively reviewed. The inclusion criteria were preoperative radiculopathy and presence of neurological deterioration without previous surgery.

The Survival of Well-Fixed Cementless Femoral Component After Isolated Acetabular Component Revision.

Background: It remains controversial whether isolated acetabular component revision or both component revision surgeries should be performed in patients with stable femoral component. The present study aimed to evaluate the survival of patients with unrevised stable uncemented femoral stem who underwent isolated acetabular component revision.

Material And Methods: A retrospective analysis was conducted in patients who underwent isolated acetabular component revision and had stable uncemented femoral component during revision hip arthroplasty between February 1998 and December 2009.
