Answer

Patients with kyphosis may have subtle neurologic abnormalities that are easily missed during examination. Magnetic resonance imaging (MRI) of the affected area can help in determining whether decompression is necessary before instrumentation and correction of the deformity.

Selection of the fusion level is important. The proximal level is usually the most cranial vertebra rotated into the kyphosis. In the distal aspect, the fusion is commonly extended to the last lordotic segment; however, some have advocated using the sagittal stable vertebra to determine the distal fusion level. [59, 60]  Recommended correction should not exceed 50%, so as to prevent junctional kyphosis at the ends of the fusion. [18]
