Pedicle subtraction metallectomy with complex posterior reconstruction for fixed cervicothoracic kyphosis : illustrative case
BACKGROUND: Iatrogenic cervical deformity is a devastating complication that can result from a well-intended operation but a poor understanding of the individual biomechanics of a patient's spine. Patient factors, such as bone fragility, high T1 slope, and undiagnosed myopathies often play a role in perpetuating a deformity despite an otherwise successful surgery. This imbalance can lead to significant morbidity and a decreased quality of life.
OBSERVATIONS: A 55-year-old male presented to the authors' clinic with a chin-to-chest deformity and cervical myelopathy. He previously had an anterior C2-T2 fixation and a posterior C1-T6 instrumented fusion. He subsequently developed screw pullout at multiple levels, so the original surgeon removed all of the posterior hardware. The T1 cage (original corpectomy) severely subsided into the body of T2, generating an angular kyphosis that eventually developed a rigid osseous circumferential union at the cervicothoracic junction with severe cord compression. An anterior approach was not feasible; therefore, a 3-column osteotomy/fusion in the upper thoracic spine was planned whereby 1 of the T2 screws would need to be removed from a posterior approach for the reduction to take place.
LESSONS: This case highlights the devastating effect of a hardware complication leading to a fixed cervical spine deformity and the complex decision making involved to safely correct the challenging deformity and restore function.
