[The clinical effects of percutaneous lumbar discectomy combined with sodium hyaluronate in the treatment of lumbar intervertebral disc herniation].

Objective: To investigate the therapeutic effect of percutaneous lumbar discectomy (PLD) combined with sodium hyaluronate (SH) injection in the treatment of lumbar intervertebral disc herniation.
Methods: Forty-eight patients suffered from lumbar disc herniation were divided into two groups and treated by PLD combined with SH injection into epidural cavity (treatment group) or single PLD (control group) respectively. All patients were followed up for 24 months. The therapeutic effects in both groups were assessed and compared according to Macnab's criterion.
Results: The patients in the treatment group got much more significant improvement than those in the control group, with shorter therapeutic course and more safety.
Conclusion: PLD combined with SH injection into epidural cavity is more effective and safety in the treatment of lumbar disc herniation than of pure PLD.
