Dorsal longitudinal T-myelotomy is a surgery to treat severe spastic paraplegia but it has recently been studied for its effects on pain. Livshits et al. (2002) conducted a case control study comparing two approaches of dorsal longitudinal T-myelotomy (i.e., Pourpre vs. Bischof II) with respect to their effectiveness in reducing pain and spasticity in people with SCI, initially refractory to more conservative approaches (N=40). Systematic follow-up assessments at six months, five and ten years were conducted. In this study, significant pain reduction was obtained with either of these surgical techniques, as measured using scores obtained from the Short Form – McGill Pain Questionnaire (Short form McGill Pain Questionnaire), the Present Pain Intensity scale, and a visual analog scale, but this appeared to be more notable with the Pourpre versus the Bischof II procedure.
There is level 3 evidence (from one case control study: Livshits et al. 2002) to support the use of dorsal longitudinal T-myelotomy procedures, in particular Pourpre’s technique, to reduce spastic pain post SCI.
