“…Compared to the other imaging methods, CT provides a clear advantage because bridging trabecular bone, which is the basic finding of arthrodesis, can be seen in detail (34). Owing to advances in CT technology, evaluation of the fusion mass has improved further with multiplanar reconstruction, artefact reduction, and sections with a thickness of 0.5-1 mm (34,(37)(38)(39).…”

“…Owing to advances in CT technology, evaluation of the fusion mass has improved further with multiplanar reconstruction, artefact reduction, and sections with a thickness of 0.5-1 mm (34,(37)(38)(39). Due to these characteristics, CT is currently the most widely accepted standard imaging method in noninvasive evaluation of spinal fusion (27,34).…”

“…Historically, the definite diagnosis of spinal fusion is made with open exploration (34)(35)(36). However, many noninvasive visualization techniques have been reported, because the clinical feasibility of open exploration is limited (27,34). In addition to standard radiographic assessments, CT and bone scintigraphy are two of the methods used.…”

A prospective evaluation was made of 65 patients with AIS scheduled for posterior spinal fusion between 2009 and 2011. Randomization was performed by using allograft and local autograft for the first 21 patients, using only local graft for the next 22 patients, and using posterior iliac crest graft and local graft for the final 22 patients according to Background/aim: This study was performed to show the efficacy of in situ local autograft with a comparison of in situ local autograft, local autograft with allograft, and local autograft with posterior iliac crest autograft. Materials and methods:In this prospective randomized study, a total of 65 adolescent idiopathic scoliosis (AIS) patients were separated into 3 groups: Group 1 using local autograft and allograft, Group 2 using local autograft only, and Group 3 using local autograft and posterior iliac crest autograft. Posterior segmental instrumentation was also applied to all patients. The mean follow-up period was 28.5 months (range, 15-40 months). Pseudarthrosis was investigated with the multiplanar and three-dimensional images obtained using multislice computed tomography, thoracolumbar bone single-photon emission computed tomography, and three-phase regional and whole body bone scintigraphy.Results: Pseudarthrosis was not observed in any patient. Fusion was obtained in all patients at the end of the follow-up periods. Conclusion:Similar results were obtained in respect of fusion in all 3 groups. Without the use of additional grafts, sufficient fusion can be achieved with the use of local autograft alone for posterior spinal fusion in patients with AIS.

“…More broadly, fusion procedures have been used in the management of spinal tumors, infection, fracture, and deformity in addition to degenerative disc disease. 7 Historically, the only means of being able to assess for spinal fusion involved surgical intervention with direct visual inspection. 8,9 While open assessment of spinal fusion still remains a useful tool in experimental models, its everyday clinical use is now only appropriate during revision surgery.…”

Study Design:Prospective cohort study.Objectives:To evaluate the role of magnetic resonance imaging (MRI) in evaluation of fusion status following anterior lumbar interbody fusion (ALIF) and compare agreement and confidence in assessing fusion or its absence on MRI to the current standard computed tomography (CT).Methods:A prospective follow up of patients undergoing surgery by 2 spine surgeons between 2012 and 2015 at a single institution. Fusion was assessed at different time points in these patients by 2 independent musculoskeletal radiologists. Fusion was analyzed in coronal and sagittal planes using both imaging modalities, with confidence being attributed on a scale of 0 to 3. Assessors were blinded to patient data.Results:Fourteen patients (25 levels) with mean follow-up of 10.2 months (range 2.4-20.3 years) and age of 41 years (range 20.7-61.5 years) were assessed. MRI within the interbody cage in coronal (κ = .58) and sagittal (κ = .50) planes had the highest interobserver agreement. CT anterior to the cage in coronal (κ = .48) and sagittal (κ = .44) planes, as well as within the cage in coronal (κ = .50) and sagittal planes (κ = .44) showed moderate agreement. Confidence anterior to the interbody cage using MRI scan was reduced when compared with remaining angles and imaging modalities.Conclusions:The study demonstrates that MRI may be a useful tool in the assessment of fusion following ALIF with results comparable to CT, and that it may have a useful role in select patients especially considering marked radiation exposure reduction.

The chapter initially discusses normal spinal development and variants. Pathology is addressed fi rst in terms of general structural vertebral anomalies. These are then applied to congenital scoliosis, kyphosis, and lordosis, as well as anomalies involving the craniovertebral junction. Discussion of spinal dysraphism follows, including tethered fi lum terminale, hydrosyringomyelia, and diastematomyelia. Congenital intraspinal tumors are briefl y reviewed. Klippel-Feil syndrome and caudal regression are presented, as well as spine manifestations of neurofi bromatosis and several other syndromes. Idiopathic scoliosis is discussed in detail, including curve measurement, imaging techniques, and treatment options. Neuromuscular scoliosis is briefl y reviewed. The chapter concludes with juvenile kyphosis.
