Does baseline thoracolumbar shape influence patterns of cervical decompensation following surgical adult spinal deformity correction?

Key Points

• This research aims to explore how different thoracolumbar shapes affect the likelihood and timing of cervical decompensation after spinal surgery.
• Analyzed baseline thoracolumbar shape using Roussouly classification
• Monitored patients after adult spinal deformity correction
• Evaluated cervical decompensation rates and timing based on morphology
• Type 1 patients developed cervical decompensation earlier than others
• Type 2 patients exhibited delayed onset of cervical decompensation
• Type 4 morphology appeared to offer some protection against decompensation
