Pseudarthrosis in Long adult spinal deformity instrumentation and fusions: risk factors and clinical outcome analysis of 228 cases

초록

The overall incidence of pseudarthrosis following adult spinal followed by deformity fusions was 15%. The thoracolumbar spine was the most common area, followed by the L4-sacrum area. The higher number of fused vertebra, fusion to the sacrum, older age, thoracolumbar kyphosis, and posterior decompression procedures significantly increased the risks of pseudarthrosis to a statistacilly significant extent. SRS-24 outcomes scores were significantly lowered with pseudarthrosis.
