Purpose:The burden of medicolegal claims in neurosurgery is increasing in the UK. Trepidation associated with malpractice claims has the potential to negatively impact surgical practice and patient safety. What are the causes of these claims and can we address them? The aim of this study was to identify the incidence and total burden of litigation claims related to neurosurgery in a London tertiary center.Methods:We retrospectively reviewed all consecutive cases of claims in neurosurgery that were reported to NHSR between March 2013 and April 2018 by St George's Hospital legal department. This was an extension of previous study by Mukherjee et al., who studied the medicolegal claims in our institution in the preceding 9-year period (2004-2013).Results:There were 18 litigation claims against neurosurgery. Claims were reviewed for clinical event, cause, likelihood of pay-out and legal outcome. Eleven claims were settled in court and seven were settled without court proceeding. All claims were spinal cases, 56% emergency admissions. Causes included faulty surgical technique (39%), delayed treatment (33%), delayed diagnosis/misdiagnosis (17%), and lack of information (11%) with a likelihood of financial success of 43%, 67%, 33%, and 100%, respectively. The highest median pay-outs were for lack of information (£2.8 million) and faulty surgical technique (£1 million). When compared to the preceding 9-year period, there a modest reduction in claims per year, despite an increase in workload. Distribution of litigation causes remained similar but overall financial burden was higher.Conclusion:Spinal surgery has the highest malpractice claim risk in neurosurgical practice. Our review shows that faulty surgical technique is the leading cause of neurosurgical claims. Claims against lack of information, although less frequent, resulted in the highest median pay-out. This study reinforces previously published data that good surgical technique and thorough process of informed consent may reduce litigation in neurosurgery.

Generalised tonic-clonic seizures have been reported to cause musculoskeletal injuries including vertebral fractures usually without resultant neurological deficit. Lumbar disc prolapse resulting in neurological deficits following seizures has not been reported. We report a 43-year-old man who presented after a generalised seizure at which point he developed worsening of low back pain and left sciatica followed by an acute foot drop. His lumbo-sacral MRI demonstrated a diffuse disc bulge at L4-5 level and a large, caudally migrated, free disc fragment with resulting severe canal stenosis at L4/5 and left lateral recess stenosis at L5/S1. He underwent urgent left L4/5 and L5/S1 micro-discectomies with resolution of his symptoms. We illustrate a rare but important treatable complication of seizures. Detailed history and clinical examination in patients with post-ictal neurological deficit should be conducted to identify the specific cause. Appropriate imaging should be performed if there remains any doubt regarding diagnosis.
