Objective To study the curative effect of limited-acupotomy therapy on chronic lumbosacral osteo-fascial compartment syndrome. Methods 59 patients were randomly recruited into a control group (with 29 patients) and a treatment group (with 30 patients). The control group was treated with general-acupotomy therapy, and treatment group was treated with limited-acupotomy therapy. Evaluate the curative effects before the first and the second therapy, and 3 months after the therapy respectively, as well as VAS pain, JOA and CODI scores. Results The curative effect was 96.56% and 100% respectively in the control group and the treatment group 3 months after the treatment. The difference between the two groups was not statistically significant(χ2＝0.19,P＞ 0.05). As to VAS pain scores, JOA and CODI scores, the difference among the three stages of the treatment were significant (in control group F＝165.70, 99.90, 106.60 respectively, in treatment group F＝279.76, 154.34, 67.36 respectively, P＜0.01)in both groups respectively, but the difference between the two groups were not significant(P＞0.05) in each stage. Conclusion Limited-acupotomy therapy was safe and effective in treating chronic lumbosacral osteo-fascial compartment syndrome.
