Short- and mid-term outcomes after posterolateral endoscopic discectomy in patients with lumbosacral junction disc herniations

Close metadata

OBJECTIVE

To analyze the short- and mid-term results of posterolateral endoscopic discectomy (PLED) in patients with lumbosacral junction intervertebral discs (IVD) herniations.

MATERIAL AND METHODS

A retrospective observational cohort study included 95 medical records of respondents (35 (36.8%) males, 60 (63.2%) females, age 21 — 72 years), who underwent PLED for lumbar IVD herniations. Mean postoperative follow-up period was 14.4±3.2 months. Clinical outcomes and incidence of complications were studied.

RESULTS

VAS scores of back and lower limb pain significantly decreased after 1, 3, 6, 9 and 12 months (p<0.01). Disability significantly improved in short- and mid-term follow-up period (Oswestry Disability Index, p<0.01). Analysis of subjective satisfaction with surgical intervention (modified MacNab scale) revealed that 92 (92.9%) respondents had excellent results. Complications occurred in 5 (5.2%) patients.

CONCLUSION

PLED is effective and safe in patients with lumbosacral joint IVD herniations. No significant complications were noted in our respondents.
