Surgical Decision for Elderly Spine Deformity Patient / 대한정형외과학회잡지

Globally, the elderly population is increasing rapidly, which means that the number of deformity correction operations for elderly spine deformity patient has increased. On the other hand, for aged patients with deformity correction operation, preoperative considerations to reduce the complications and predict a good clinical outcome are not completely understood. First, medical comorbidity needs to be evaluated preoperatively with the Cumulative Illness Rating Scale for Geriatrics or the Charlson Comorbidity Index scores. Medical comorbidities are associated with the postoperative complication rate. Managing these comorbidities preoperatively decreases the complications after a spine deformity correction operation. Second, bone densitometry need to be checked for osteoporosis. Many surgical techniques have been introduced to prevent the complications associated with posterior instrumentation for osteoporosis patients. The preoperative use of an osteogenesis inducing agent

The Role of the Pelvis in Sagittal Alignment of Lumbar Degenerative Disease Patients

STUDY DESIGN: Literature review. OBJECTIVES: To present updated information on the relationship of the pelvis and lumbar degenerative disease (LDD) patients and to emphasize the importance of the pelvis in sagittal alignment of LDD patients. SUMMARY OF LITERATURE REVIEW: Although the relationship of the pelvis and sagittal alignment of LDD patients is controversial, many authors have reported a significant impact of the pelvis on LDD sagittal alignment. MATERIALS AND METHODS: The authors identified references through a literature search on the pelvis and LDD and continuous monitoring of the literature during the past 30 years. RESULTS: The pelvis and lumbar levels were related to whole-body sagittal alignment. The pelvis is also closely related to sagittal alignment of LDD patients. Therefore, the entire area should be regarded as a lumbopelvic complex. CONCLUSIONS: We need to consider the concept of a lumbopelvic joint and lumbopelvic lordosis, not a lumbosacral joint and lumbar lordosis. We must also evaluate the lumbopelvic complex to assess whole-body sagittal alignment and dynamic balance.
