“…The spine is a complex structure that transmits loads from the upper body through the pelvis into the lower extremities [3,7] . A spinal motion segment is the smallest functional unit addressing spinal biomechanics.…”

“…Posterior spinal column reconstruction has been performed for decades using different combinations of plates or rods with hook/wire/pedicle screw systems to form posterior spinal construct devices for different spinal levels [3,5,7] . A posterior approach is usually used when posterior decompression is required in addition to fusion as in degenerative spinal disease.…”

“…It avoids the high-risk of the anterior approach in these regions, while it is mostly avoided in the cervical region for cord manipulation risks at that level [3,4] . Posterior fusion uses autografts placed along decorticated facets, laminae and/or transverse processes [7] . In PLIF, bilateral partial laminectomies are performed and are followed by diskectomy (Figure 1).…”

“…In PLIF, bilateral partial laminectomies are performed and are followed by diskectomy (Figure 1). Bone graft material is packed into the anterior disk space before the insertion of one or two interbody spacers; placed side by side; and packed with graft material [4,7,8,18] . When there is a severe loss of disk space height and when the insertion of a posterior interbody spacer might cause neurologic compromise, Trans-laminar inter-body fusion with cortical screws is used as a simple method of posterior fixation.…”

“…Early surgeries relied upon extended bracing for solid fusion to occur with considerably long convalescence periods [3] . Currently, a vast array of implants and surgical approaches are available for spinal surgeries to aid graft incorporation with early mobility and shorten postoperative recovery period [3][4][5][6][7][8][9] the loads acting on the spine, usually until solid biological fusion occurs [5][6][7][8][9] . Subsequent instrument failure occurs if solid bony fusion is not achieved [5][6][7][8][9] .…”

The interpretation of spinal images fixed with metallic hardware forms an increasing bulk of daily practice in a bus�� imaging department. Radio�ogists are required to be familiar with the instrumentation and operative options used in spinal fixation and fusion procedures, especia�� in his or her institute. This is critica� in eva�uat-ing the position of imp�ants and potentia� comp�ications associated with the operative approaches and spinal fixation devices used. Thus, the radiologist can play an important role in patient care and outcome. This review out�ines the advantages and disadvantages of common�� used imaging methods and reports on the best yield for each modality and how to overcome the problematic issues associated with the presence of metallic hardware during imaging. Baseline radiographs are essentia� as the�� are the base�ine point for eva�uation of future studies shou�d patients deve�op s��mptoms suggesting possib�e comp�ications. The�� ma�� justif�� further imaging workup with computed tomography, magnetic resonance and/or nuc�ear medicine studies as the eva�u-ation of a patient with a spinal implant involves a multimodality approach. This review describes imaging features of potential complications associated with spinal fusion surgery as well as the instrumentation used. This basic knowledge aims to help radiologists approach ever��da�� practice in c�inica� imaging.

The frequency and variety of spinal instrumentation has increased tremendously over the past 100 years, and imaging plays an important role in evaluating the postoperative spine. Although assessment of spinal hardware often involves a multimodality approach, plain radiographs are the most commonly used modality, given accessibility, cost, relatively low radiation dose compared with computed tomography, and provision of positional information. An approach to assessment of plain radiographs of the postoperative spine is discussed, and examples of common postoperative complications are provided, including infection, hardware failure, incomplete fusion, and junctional failure.
