The aim of this systematic review and meta-analysis was to evaluate the safety and efficacy of surgical versus conservative management of SCCMs.</p><p><strong>Methods: </strong>Following PRISMA guidelines, this study included articles published in full-text form comparing the outcomes following conservative and surgical management of SCCMs. Collected variables included the total number of patients, spine level, resection, myelotomy, follow-up duration, bleeding, motor weakness, pain, bladder and/or bowel dysfunction, and neurological improvement or deterioration after discharge.

These findings parallel management strategies used for brainstem cavernomas, for which surgery is reserved for cases with low surgical risk and worsening neurological symptoms.

The algorithm begins broadly by stratifying patients as either symptomatic or asymptomatic. Asymptomatic patients can be considered as having successful fusions after 12 months. If patients are symptomatic, the imaging modality and healing characteristics are based on the quality of pain experienced. For radicular pain, fusion evaluation includes a flexion/extension (F/E) radiograph to assess for foraminal compression, trabecular bridging, minimal angular rotation, minimal translational movement, and minimal halo sign. For axial pain, a helical CT scan is recommended, with characteristics of success that include trabecular bridging, lack of radiolucent shadowing, lack of visible bone or hardware fracture, lack of cystic or sclerotic changes, low subsidence level near the graft, and minimal screw-rod construct migration.
