ReviewImaging and management of postoperative spine infection.
Imaging evaluation of postoperative spinal infection is challenging. A systematic approach and keen understanding of multimodality imaging techniques, as well as knowledge of the patient's surgical procedure and clinical presentation, are critical for the radiologist to render an accurate diagnosis. Because of the overlap between diagnostic imaging findings in the postoperative spine and the infected spine, in those situations in which the index of clinical suspicion for spine infection is high, then immediate consideration ought to be given to performing a spine biopsy.

This article reviews the imaging of lumbar spinal fusion and its major indications. The most common procedures are described for the purpose of allowing understanding of postoperative imaging. Imaging options are reviewed for preoperative workup, intraoperative guidance, and postoperative purposes. Examples of hardware integrity, fusion, and loosening are provided.

ReviewRadiologic evaluation and management of postoperative spine paraspinal fluid collections.
Postoperative paraspinal fluid collections can present a management dilemma to both radiologists and surgeons. Although many of these collections present as incidental findings and are unrelated to the presenting signs and symptoms that led to the imaging study, certain collections in the context of the appropriate clinical scenario may require additional evaluation and even emergent intervention. This article reviews those collections that are most frequently encountered and suggests management strategies that may assist in the evaluation and management of the patient.

Imaging of the postoperative spine is common, although it remains a difficult task for radiologists. This article presents an overview of common surgical approaches and spinal hardware, and specific complications that may be associated with each procedure. In addition, expected postoperative changes and complications that are common among procedures, with their differential diagnosis and imaging features, are discussed.

Primary or metastatic spine tumors can present with pain and/or neurologic compromise depending on their location within the spinal axis. Metastases and multiple myeloma comprise most of these lesions. ⋯ Pre- and postoperative imaging plays a critical role in the diagnosis and management of patients with spinal tumors. This article reviews postoperative imaging of the spine, including imaging protocols, immediate and long-term routine imaging findings, and emergent findings in symptomatic patients.
