Therapeutic Effect Of Ultrasound-guided Small Needle Knife Combined With Pain Point Injections On Lumbar Buttock Myofascial Pain Syndrome

OBJECTIVE:This study retrospectively analyzed and compared the two methods of ultrasound-guided small needle knife combined pain point injection and traditional small needle knife treatment for the relief of pain,dysfunction symptoms and hip range of motion in patients with chronic lumbar and hip myofascial pain syndrome,the degree and the occurrence of adverse reactions after treatment were evaluated for their efficacy and safety.METHODS:This study collected patients who were treated in the outpatient and inpatient departments of the Second Affiliated Hospital of Nanchang University from January2018 to August 2019 due to chronic waist and hip myofascial pain syndrome.A total of 70 patients were treated with knife combined with pain point injection and traditional small needle knife.Patients receiving ultrasound-guided small needle knife combined with pain point injection were treated as the ultrasound group(n = 35),16 males and 19 females;patients treated with traditional small needle knife were treated as the control group(n = 35).There were 14 males and 21 females.The patient's visual analog scale(VAS)score,modified Oswestry dysfunction index(ODI)score,and before and after treatment were obtained by consulting historical case data and outpatient follow-up.Data on hip range of motion(ROM)and adverse reactions such as pain,bleeding,and nerve damage at the treatment site.The data results were analyzed statistically using SPSS 22.0 software.RESULTS:All patients underwent complete follow-up.There were no significant differences in gender,age,course of disease,lesion site,and VAS and ODI scores between the two groups of patients(P> 0.05).After treatment,the pain,dysfunction symptoms and range of motion of the hip joints in the two groups were significantly improved.Among them,the VAS scores of the ultrasound group at 1 day and 3 months after treatment were significantly lower than those of the control group(P<0.05);the patients of the ultrasound group had significantly lower ODI scores at 1 day,2 weeks,and 3 months after treatment.(P < 0.05),especially at 3 months after treatment(P<0.01);hip joint flexion,extension,and external rotation ROM were significantly improved in both groups(P<0.05),and the ultrasound group patients The improvement of the forward flexion and external rotation ROM was better than that of the control group,and there was a significant statistical difference between them(P<0.05).However,the improvement of the internal rotation ROM of the hip joints in the two groups did not reach a significant level(P>0.05).Adverse reactions occurred.The pain time at the treatment site of patients in the ultrasound group was1(1~2)days,which was significantly shorter than that of the control group at 3(2~3)days.A total of 4 patients in the control group experienced hematomas at the treatment site,and there was no significant bleeding in the ultrasound group occurred;no nerve injury occurred in both groups of patients.CONOLUSION:Both groups of patients achieved satisfactory clinical results after treatment.Ultrasound-guided small needle knife combined with pain point injection was more effective in improving pain symptoms and dysfunction in patients with myofascial pain syndrome,and there was no obvious adverse effect in the ultrasound group after treatment.The reaction happened.Therefore,ultrasound-guided small needle knife combined with pain point injection for the treatment of chronic lumbar and gluteal myofascial pain syndrome is accurate,targeted at the cause,and has a significant effect.It is a safe and effective treatment method.Worthy of clinical application.
