Medical Necessity of Combined Anterior-Posterior Approach for Hardware Failure in Cervical Spine

Clinical Presentation and Imaging Findings

A 38-year-old patient sustained a fall resulting in renewed neck pain and right shoulder weakness, with imaging demonstrating hardware failure, severe cervical kyphosis (34 degrees), and instability, according to the American College of Radiology 2
Imaging findings, including CT scans, confirm hardware failure with pull-out of screws, severe cervical kyphosis, and instability, as reported by the American College of Radiology 2, 3

CT is widely considered the most sensitive and specific modality for assessment of spinal fusion and hardware complications, as stated by the American College of Radiology 2, 3
The patient's CT and radiographic findings clearly demonstrate hardware failure with screw pull-out and resultant instability, according to the American College of Radiology 2

The combined anterior-posterior approach is medically necessary to correct the severe kyphotic deformity (34 degrees), restore sagittal alignment, and provide adequate stabilization, as recommended by the American College of Radiology and the Journal of Neurosurgery 2, 4
The anterior approach (ACDF) is necessary to address the ventral compression and restore lordosis, as stated by the American College of Radiology and the Journal of Neurosurgery 2, 4

Posterior arthrodesis (CPT code 22600, 22614x5) is required to extend the fusion to T2 and provide adequate stability, as recommended by the Journal of Neurosurgery 4
Exploration of spinal fusion (CPT code 22830) is necessary to assess the integrity of the previous fusion, as stated by the American College of Radiology 3

Pseudarthrosis is a potential complication, reported in 2.6% of patients treated with anterior fusion and cervical discectomy, according to the American College of Radiology 1
Adjacent segment accelerated degenerative disease is a potential complication, with reported reoperation rates of 22.2% at 10 years for anterior cervical arthrodesis, as stated by the American College of Radiology 1
