Abstract
ObjectiveTo compare the efficacy of paravertebral injection of botulinum toxin type A (BoNT-A) with silver needle therapy in the treatment of patients with failed back surgery syndrome induced by soft-tissue.
MethodsSixty patients, from January 2019 to December 2019, in Pain Department of Foshan Chancheng Central Hospital, were collected in this retrospective study. All patients were divided into BoNT-A group and internal heated needle group according to the treatment method, 30 cases in each group. Patients were received BoNT-A≤100 U in paravertebral muscles in BoNT-A group, while patients were received internal heated needle therapy, 20-30 target points, 20 min, 42 ℃, at soft tissue in the surgical area or adjacent segments in internal heated needle group. All patients were received the treatment once every 3 days, and 2 times during hospitalization in the two groups. VAS and Oswestry disability index were recorded before the treatment and 24 h, 3 d, and 1, 2, 3 months after the treatment.
ResultsThere was no significant difference in VAS and Oswestry disability index before the treatment between two groups (t=1.53, P>0.05; t=-0.05, P>0.05). Comparing with pretreatment, VAS was significantly different at each time point between two groups after the treatment (F=327.40, P<0.05), and there was an interaction between time and group (F=31.47, P<0.05), there was significantly different in VAS between two groups (F=734.65, P<0.05). Oswestry disability index was significantly different at each time point between the two groups (F=475.65, P<0.05), and there was an interaction between time and group (F=64.29, P<0.05). Oswestry disability index in internal heated needle group was superior to BoNT-A group (F=96.85, P<0.05).
ConclusionsInternal heated needle therapy can relieve the pain in patients with soft tissue-derived failed back surgery syndrome, and is superior to the injection of soft tissue botulinum toxin type A in the paravertebral muscles.
