| Name | Spinal fusion |
spinal fusion is a surgical procedure that permanently connects two or more vertebrae in the spine to eliminate motion between them. Surgeons perform the operation to reduce pain, correct deformity, or stabilize the spine after trauma, tumor resection, or infection. Indications, techniques, and outcomes have evolved with contributions from institutions like Mayo Clinic, Johns Hopkins Hospital, and innovations associated with surgeons at Cleveland Clinic and Hospital for Special Surgery.
Spinal fusion is indicated for conditions such as degenerative disc disease seen in patients treated at Massachusetts General Hospital, spondylolisthesis discussed in literature from Harvard Medical School, spinal stenosis evaluated by teams at Stanford Health Care, vertebral fractures from incidents like the 2004 Indian Ocean earthquake survivors, spinal deformities including scoliosis described by specialists at Shriners Hospitals for Children and kyphosis reviewed in publications from Oxford University Press. It is also used after oncologic resections for tumors like metastatic lesions studied at MD Anderson Cancer Center and primary bone tumors reported by Memorial Sloan Kettering Cancer Center. Contraindications are considered by panels at World Health Organization and national bodies such as the American Academy of Orthopaedic Surgeons.
Approaches include posterior lumbar interbody fusion popularized in texts from Philadelphia College of Osteopathic Medicine, anterior lumbar interbody fusion developed through case series at University of California, Los Angeles, and transforaminal techniques refined by teams at University of Toronto. Minimally invasive strategies draw upon technology from Intuitive Surgical and instrumentation studies in journals associated with BMJ Publishing Group. Navigation and intraoperative imaging use platforms from Siemens Healthineers and GE Healthcare and reference anatomical atlases from Gray's Anatomy and procedural standards cited by National Institutes of Health. Surgeons plan fixation using pedicle screw systems introduced by companies like Medtronic and rod constructs evaluated by researchers at Karolinska Institutet.
Graft choices include autograft harvested from the iliac crest as described in protocols at Cleveland Clinic, allograft sourced from tissue banks such as American Association of Tissue Banks, and synthetic options including ceramics and bioactive glass commercialized by Stryker and Zimmer Biomet. Recombinant human bone morphogenetic protein-2 (rhBMP-2) was developed by scientists at Genentech and has been the subject of regulatory review by the Food and Drug Administration. Interbody cages are manufactured by firms like DePuy Synthes and incorporate materials researched at Massachusetts Institute of Technology and Johns Hopkins University laboratories. Posterior instrumentation systems trace design lineage to early work at Mayo Clinic and innovations presented at meetings of the North American Spine Society.
Outcomes are measured using scales validated in studies from University of Oxford and Karolinska Institutet and reported in journals published by Elsevier and Wiley-Blackwell. Fusion rates vary with technique and graft choice; long-term follow-up studies by teams at Duke University and University College London quantify adjacent segment disease, pseudoarthrosis, and hardware failure. Complications include infection managed according to guidelines from the Centers for Disease Control and Prevention, neurologic injury documented in case series from Johns Hopkins Hospital, thromboembolism with prevention strategies from Royal College of Physicians, and chronic pain pathways investigated at McGill University and University of California, San Francisco. Health policy and cost-effectiveness analyses have been produced by researchers at The World Bank and Organisation for Economic Co-operation and Development.
Postoperative protocols often follow multidisciplinary programs developed at Spaulding Rehabilitation Hospital and Sheba Medical Center, integrating physiotherapy approaches influenced by curricula at University of Sydney and occupational therapy frameworks from University of Toronto. Pain management regimens reference guidelines by the American Pain Society and pharmacologic studies from Pfizer and GlaxoSmithKline. Return-to-work criteria and functional outcome measures are informed by research at Columbia University and vocational rehabilitation models from Department of Veterans Affairs.
The rise in procedure rates has been documented in epidemiologic studies by Centers for Disease Control and Prevention and analyses published by The Lancet and JAMA. Historical milestones include early fusion concepts emerging in the 19th century in reports from European clinics associated with Charité – Universitätsmedizin Berlin and later technical advances influenced by pioneers working at Mayo Clinic and Johns Hopkins Hospital. Policy controversies and innovations in device regulation involved agencies such as the Food and Drug Administration and professional societies including the North American Spine Society and American Association of Neurological Surgeons.
