摘要

Objective:To investigate clinical effect of transcutaneous refrigeration of posterior ramus of spinal nerve in the treatment of lumbodynia.Method:426 patients suffered from low lumbodynia were diagnosed by neurolocation techniques.Transcutaneous refrigeration of posterior ramus of spinal nerve was done using liquid nitrogen.Result:Follow-up was performed for 4 months and 5 yars,and showed excellent therapeutic effect in 380 ases,good in 11 cases,not bad in 16 cases,and poor in 19cases including 6 with recurrence.Good rats was 91.8% .Therapeutic effect is satisfying.Conclusion ranscutaneous refrigeraiton of posteior ramus of spinal nerve is characterized by less injury and favorable therapeutic effect.
