Epidemiology of the causes of complaints after discectomy collected from a French insurance company.

INTRODUCTION: Lumbar discectomy is a frequent procedure performed by surgeons from specialties at risk of patient complaints. The objective of the study was to analyze the causes of litigations following lumbar discectomy to be able to reduce their frequency.

MATERIAL AND METHODS: This observational, retrospective study was carried out at a French insurance company (Branchet). All files opened between the 1st of January 2003 and the 31st of December 2020, following lumbar discectomy without instrumentation and without any other associated code, undertaken by a surgeon insured by Branchet, were analyzed. The data was extracted from the database by a consultant from the insurance company and analyzed by an orthopedic surgeon.

RESULTS: One hundred and forty-four records met all inclusion criteria and were complete and available for analysis. Infection was the leading cause of litigation, responsible for 27% of complaints. Residual postoperative pain was the second cause of complaint with 26% of cases, of which 93% had persistent pain. Neurological deficits were the third cause of complaint with 25% of cases among which 76% were related to the appearance of a deficit and 20% related to the persistence of an existing deficit. Early recurrence of herniated disc also appeared as a cause of complaint, accounting for 7% of cases.

CONCLUSION: Surgical site infection, persistence of pain, and the appearance or persistence of neurological disorders are the primary causes of complaints leading to investigation in the aftermath of lumbar discectomy. It seems essential to us that this information be brought to the attention of surgeons to enable them to better adapt their explanations in the delivery of preoperative information.
