“…The classic approach for the cervical spine is the Smith-Robinson anterior approach, which is used for anterior access to the C2-T1 cervical spine level in several procedures, including anterior cervical discectomy and fusion (ACDF), anterior cervical corpectomy and fusion, and cervical disk replacement. A transoral approach is needed to access the clivus and the C1 and C2 vertebral bodies (25). The posterior approach, which is less preferred, may be performed for laminoplasty, laminectomy, and posterior instrumentation.…”

“…The posterior approach, which is less preferred, may be performed for laminoplasty, laminectomy, and posterior instrumentation. Posterior cervical spinal instrumentation involves placing lateral mass screws in the C3-C7 vertebral bodies and transpedicular screws in the C2 vertebral body with vertical rods bilaterally (24,25). In certain clinical scenarios, a combined anterior and posterior approach may be performed.…”

“…Single screws can provide stability and compression for the healing of fractures, such as unilateral pars fracture; however, they are rarely indicated. Pairs of transpedicular, translaminar, and transarticular screws serve as anchors for posterior connecting rods in posterior spinal fixation constructs to achieve osseous spinal fusion and intervertebral arthrodesis (25). Screws are used to fix plates to vertebral osseous elements to provide stability for osseous spinal fusion, such as that in ACDF procedures (21).…”

“…Interbody grafts and cages, which may also be referred to as intervertebral spacers, have varying designs and are commonly used to restore disk height after discectomy and promote immobilizing osseous bridging across the disk space (Fig 3). Solid interbody cages usually are hollow and thus can be packed with other biologic materials (7,25). Interbody grafts may be composed of metallic alloys such as titanium; plastics such as polyetheretherketone; carbon fibers; and ceramics.…”

“…After spinal surgery, postoperative collections are common and include seroma, hematoma, abscess, and pseudomeningocele, which may be symptomatic or incidental findings (25). Accurate differentiation of the various collection types is important for implementing the most appropriate management.…”

During the past 2 decades, the number of spinal surgeries performed annually has been steadily increasing, and these procedures are being accompanied by a growing number of postoperative imaging studies to interpret. CT is accurate for identifying the location and integrity of implants, assessing the success of decompression and intervertebral arthrodesis procedures, and detecting and characterizing related complications. Although postoperative spinal CT is often limited owing to artifacts caused by metallic implants, parameter optimization and advanced metal artifact reduction techniques, including iterative reconstruction and monoenergetic extrapolation methods, can be used to reduce metal artifact severity and improve image quality substantially. Commonly used and recently available spinal implants and prostheses include screws and wires, static and extendable rods, bone grafts and biologic materials, interbody cages, and intervertebral disk prostheses. CT assessment and the spectrum of complications that can occur after spinal surgery and intervertebral arthroplasty include those related to the position and integrity of implants and prostheses, adjacent segment degeneration, collections, fistulas, pseudomeningoceles, cerebrospinal fluid leaks, and surgical site infections. Knowledge of the numerous spinal surgery techniques and devices aids in differentiating expected postoperative findings from complications. The various types of spinal surgery instrumentation and commonly used spinal implants are reviewed. The authors also describe and illustrate normal postoperative spine findings, signs of successful surgery, and the broad spectrum of postoperative complications that can aid radiologists in generating reports that address issues that the surgeon needs to know for optimal patient management.©RSNA, 2019.

En-bloc resection of spinal tumours is a complex procedure with significant morbidity and mortality. The extensive resection leaves a large soft tissue and osseous defect requiring reconstruction. Following enbloc resection, there may be complications relating to both the removal of the tumour and the subsequent reconstruction. This paper outlines the imaging appearances of the frequently encountered complications in our experience. The primary aim is to improve the confidence of the radiologist when reporting imaging following spinal en-bloc resection, however we believe this is also useful for the spinal and orthopaedic surgeons in assessing the patients following en block resection.
