![]() Surgery, intact implants are generally left in place for life. Be-cause of the morbidity associated with repeated Stability during bone fusion, and their function is complete when this The most widely accepted cause of low-back pain and the underlyingĬoncept promoting the use of spinal fusion is nonphysiologic movement of Mulholland 8 inĪ recent review of instability and low-back pain hypothesized that theĬause of low-back pain could be due to abnormal disc loading. Stability is described as resistance of the spine to deformation under physiologic stress. Potential complications to properly appraise postoperative images. Surgical methods used in spinal fusion, types of instrumentation and Radiologists should also be familiar with different Modalities is necessary for optimal evaluation of patients with spinal Knowledge of the advantages and limitations of different imaging Instrumentation, possible complications and the extent of bone-graftįusion. Imaging is used to assess disease progression, positioning of Includes the category of degenerative disc diseases. The current indication for spinal arthrodesis is broad and it Spondylolisthesis, congenital deformities, spinal instability in trauma Spinal tuberculosis in 1911 5–7 there have been a great manyĪdvances in surgical methods and instrumentation, as well as many more Spinal fusion surgery by Fred Albee and Russel Hibbs in treatment of 3,4 Since the initialĭescription of spinal instrumentation by Harda in 1889 and subsequent Syndrome can be prevented to a large extent by meticulous pre- and Pseudarthrosis or continued natural progression of disease. The syndrome can result from: mistakenĭiagnoses, technique error, poor application, inappropriate indication, In theīest of all situations, this syndrome occurs after a minimum of 20% of Failed back surgery syndrome (FBSS) is definedĪs failure to relieve lower back pain symptoms following surgery.
