Abstract:Objective To investigate the impacts of intervertebral foramen endoscopic surgery combined with silver needle hyperthermia therapy on lumbar spine function and local tenderness in patients with lumbar disc herniation (LDH).Methods From April 2020 to March 2023, 100 LDH patients were randomly devided into a control group (50 cases) and an observation group (50 cases) through random number table method. The control group was treated with intervertebral foramen endoscopic surgery combined with conventional lumbar and dorsal muscle training, while observed group was treated with intervertebral foramen endoscopic surgery combined with silver needle warm therapy. The lumbar function, local tenderness, laboratory indicators, and adverse reactions were compared.Results The Japanese Orthopaedic Association (JOA) score increased in both groups after treatment, and observed group had obviously higher scores, the differences were statistically significant (P < 0.05); After treatment, both groups showed a decrease in pain visual analogue scale (VAS) score, and observed group had obviously lower scores, the differences were statistically significant (P < 0.05); The levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), prostaglandin E2 (PGE2), and 5-hydroxytryptamine (5-HT) in both groups decreased after treatment, and the observed group showed a more obvious decrease in all indicators, the differences were statistically significant (P < 0.05); The incidence of adverse reactions was 4.00% (2/50) in observed group and 20.00% (10/50) in the control group, adverse reactions in observed group were obviously fewer, the difference was statistically significant (P < 0.05).Conclusion The combination of intervertebral foramen endoscopic surgery and silver needle hyperthermia therapy can effectively improve lumbar spine function and alleviate local tenderness symptoms in patients with LDH. It is worthy clinical application.
