[Sacrococcygeal gap injection for the treatment of failed back surgery syndrome]
Objective:
To explore the clinical effect of the sacrococcygeal space injection for the treatment of failed back surgery syndrome.
Methods:
From July 1998 to October 2012,47 patients with failed back surgery syndrome were treated and included 39 males and 8 females with an average age of 61.5 years old ranging from 35 to 89 years old. Among them,41 patients experienced one time of operation, 6 patients with twice of operation. Forty-one patients underwent single,bilateral fenestration or central laminectomy decompression, discectomy. Six patients underwent total laminectomy discectomy and inter body fusion and pedicle screw fixation. All patients were examined by X-ray plain film, CT or MRI before treatment. The anticoagulation was discontinuation before treatment. The needle was put into the sacrococcygeal gap at prone position in the sense of frustration,suction without cerebrospinal fluid and blood,with injection of Mailuoning (Chinese characters: see text) 15 ml. The pain was assessed by VAS before and after treatment. The Oswestry low back pain disability index and survival quality interference degree were evaluated.
Results:
At 1 month after treatment,the pain VAS decreased from 59.24 +/- 17.35 before treatment to 19.19 +/- 11.19 after treatment (P < 0.05); The Oswestry low back pain disability index decreased from (41.35 +/- 9.87)% before treatment to (23.17 +/- 17.56)% after treatment (P < 0.05); The survival quality interference degree decreased from 6.5 +/- 2.2 before treatment to 2.6 +/- 1.4 after treatment (P < 0.05).
Conclusion:
The sacrococcygeal gap injection for treatment of failed back surgery syndrome has advantages of simple, safe, fewer complications, and low treatment cost.
