Abstract
Objective: NHS Patients can wait up to 18 months for non-urgent spine surgery. The intended procedure is determined by the outpatient MRI scan. Do changes occur within the spine during the wait for surgery? Would the changes affect the operative decision?
Design: A Prospective study.
Subjects: 105 patients listed for elective lumbar spine surgery at a district general hospital
Outcome Measures: If the MRI scan is over six months old, a second scan is performed prior to surgery. Changes that alter the operative decision are noted.
Results: Forty-four percent discectomy, 17% decompression, and 19% fusion plus decompression patients cancelled surgery due to improvement in symptoms. None of the spinal fusion patients cancelled. Fourteen percent discectomy; 12.5% decompression; 25% fusion; 19% fusion plus decompression and 65% fusion plus discectomy patients had different procedures after the second MRI. Changes seen include disc resolution, pro-lapse at a new level, progressive modic changes and compression at different levels.
Conclusions: We do not support the fact that patients may have to wait up to 18 months before having elective spinal surgery. However, a significant numbers of discectomy and decompression patients found that their symptoms improved enough to decline surgery. No patient who had been listed for fusion alone got better. Due to changes seen on the second MRI scan, one in six operations were different to the initial planned procedure. Could a surgeon failing to request a further up to date scan prior to surgery therefore be considered negligent?
