Case Example 9
54 yo male with ankylosing spondylitis and progressive kyphosis.
Case review: 54 yo male with ankylosing spondylitis and with progressive kyphotic spinal deformity. He developed a worsening rigid forward stooping posture where he was unable to gaze forward, decreased ability to ambulate, and chronic disabling back pain. Preop xrays and picture demonstrate sagittal imbalance with thoracic kyphosis measuring 88 degrees, lumbosacral lordosis 8 degrees, PI 62 (mismatch of 52 degrees) and SVA >30 cm with a fixed forward stooping posture.
The patient was treated with a pedicle subtraction osteotomy involving resection of the L3 vertebral body and posterior spinal fusion and instrumentation from the T10 to the sacrum. Postop xrays demonstrate correction of kyphosis with LS curve measuring 54 degrees lordosis and restoration of spinal balance with SVA below 12 cm and normalization of chin brow angle.
