Percutaneous discectomy under CT and fluoroscopy guidance: an international multicentric study

Patient-Reported Outcomes and Return to Work after CT-Guided Percutaneous Lumbar Discectomy: A Prospective Study

PURPOSE

To evaluate the effectiveness of percutaneous lumbar discectomy (PLD) under computed tomography (CT) guidance on pain and functional capacities and to estimate the speed of recovery by assessing the time to return to work.

MATERIALS AND METHODS

Patients treated with PLD were prospectively included between December 2019 and April 2021. Data regarding pain, duration of symptoms, analgesia intakes, time of absence from work, and the Oswestry disability index (ODI) were collected. Patients were followed-up during 6 months. Duration of hospitalization and time to return to work were reported. The Fisher test was used to compare nominal variables, the Kruskal-Wallis test to compare ordinal variables, and the Student t test to compare quantitative continuous variables.

RESULTS

A total of 87 patients were evaluated (median age, 56 years; interquartile range [IQR], 43-66 years). The median ODI decreased from 44 (IQR, 33-53) to 7 (IQR, 2-17) at 6 months (P < .001). The median visual analog scale score decreased from 8 (IQR, 8-9) to 2 (IQR, 0-3) within 6 months (P < .001). In total, 96.5% of patients were discharged on the day of the procedure, and 3.5% were discharged on the following day. No severe adverse events were reported according to the Society of Interventional Radiology (SIR) classification system. Of the 57 patients previously employed, 50 were able to return to work during the follow-up, with a median time of 8 days (IQR, 0-20 days).

CONCLUSIONS

Symptomatic lumbar disc herniation can be successfully treated using PLD, resulting in significant improvement in symptoms and functional capacities and a fast return to work.
