AMSLU(™) Cage을 이용한 경추체 전방융합술의 초기경험 = Preliminary Clinical Experience of Anterior Cervical Interbody Fusion with the AMSLU(™) Cage

다국어 초록 (Multilingual Abstract)

Objective : The authors investigate the effectiveness and the demerits of the AMSLUTM cervical cage used in
cervical spinal fusion for correction of cervical degenerative disc disease.
Methods : A total of 19 patients with cervical degenerative disc disease underwent anterior microdiscectomy and
the AMSLUTM cage fusion. We made a retrospective comparative analysis between cases using the AMSLUTM cage
and the classical autogenous iliac crest graft(AICG) with plate fixation about operative time, blood loss and hospital
stay. The patient's neurological and functional outcomes were assessed on the basis of the modified Odom's criteria.
Results : The use of the AMSLUTM cage was found to save operative time (mean, 153±52min : P=0.004) and blood
loss (mean, 236±171cc : P=0.032) as compared with the use of AICG. There was no donor-site complications and all
patients were tolerable to ambulation at 1 day postoperatively. The patient’s clinical success rate was 89% on discharge
and 84% at 6 months postoperatively.
Conclusion : The use of the AMSLUTM cage provides several advantages : no donor-site complications, brief
instrument procedures, short operative time, small amount of blood loss and satisfactory clinical success rate. But it
also has many limitations : short follow up period, kyphotic change and subsidence. Further investigations and
clinical applications are necessary to use AMSLUTM cage in cases of spondylolisthesis and traumatic cervical disease.
