Indications and Possibility of Short Fusion in Adult Spine Deformity

Adult spinal deformity (ASD) poses a growing public health challenge in aging societies. As global life expectancy rises and populations age rapidly, ASD prevalence has increased correspondingly. Radiographic evidence of spinal deformity—including scoliosis, kyphosis, or sagittal imbalance—is observed in over 30% of adults aged 60 and older [1]. In high-risk populations such as osteoporotic postmenopausal women, prevalence may exceed 60% [2].
