To explore the clinical effect of ultrasound-guided needle knife dissection combined with lumbar inclined plate method in the treatment of gluteal epithelial nerve compression syndrome based on the theory of“bone alignment and tendon flexibility”.

Sixty patients with gluteal epithelial nerve compression syndrome who received treatment in the Orthopedic Department of the Affiliated Hospital of Liaoning University of Traditional Chinese Medicine from January 2023 to January 2024 were selected as the study subjects.Using the random number allocation method，the patients were randomly divided into a control group（30 cases）and an experimental group（30 cases）.The control group was treated with ultrasound-guided needle knife dissection，while the experimental group was treated with a combination of ultrasound-guided needle knife dissection and lumbar inclined plate dissection under the guidance of the“bone alignment and tendon flexibility”theory.The treatment period for both groupswas 4 weeks.After treatment，the clinical efficacy，Visual Analog Scale（VAS）score，Oswestry Disability Index（ODI）score，shear wave Young'smodulus values of the lumbar multifidus and psoasmajor muscles，and the changes in surface electromyography were compared between the two groups.

Compared with the control group，the experimental group had a higher clinical total effective rate after 4 weeks of treatment，but there was no statistically significant difference in the total effective rate between the two groups（P>0.05）.Compared with those before treatment，VAS scores and ODI scores in both groups showed a decreasing trend after treatment and 4 weeks follow-up（P<0.05）.Compared with those of the control group，the VAS score and ODIscore of the experimental group were lower after treatment and 4 weeks follow-up（P<0.05）.Compared with those before treatment，the shearwave Young'smodulus values of the bilateral multifidus and lumbar muscles in the experimental group showed a decreasing trend after treatment and 4 weeks follow-up（P<0.05）.Compared with those before treatment，there was no statistically significant difference in the shearwave Young'smodulus values of the bilateral multifidus and lumbar muscles in the control group after treatment and 4 weeks follow-up（P>0.05）.Compared with the control group，the shearwave Young'smodulus values of the bilateral multifidus and lumbar muscles in the experimental group were lower after treatment and 4 weeks follow-up（P<0.05）.Compared with those before treatment，the average amplitude of electromyography on both sides of the multifidus and lumbar muscles in the experimental group showed an increasing trend after treatmentand 4 weeks follow-up（P<0.05）.Compared with those before treatment，there was no statistically significant difference in the average amplitude of surface electromyography of the multifidus and psoasmajormuscles in the control group after treatmentand 4 weeks follow-up（P>0.05）.Compared with those in the control group，the average amplitude of surface electromyography of the multifidus and psoasmajor muscles in the experimental group was higher after treatment and 4 weeks follow-up（P<0.05）.

The combination of ultrasound-guided needle knife dissection method and lumbar inclined plate method based on the concept of“bone alignment and tendon flexibility”can significantly improve the short-term and long-term clinical effects of treating gluteal epithelial nerve compression syndrome，with advantages such as high safety，minimal trauma and rapid recovery.
