calcitonin and Phantom-Limb

In this prospective clinical study we examined the intravenous application of salmon-calcitonin in eight patients with severe phantom limb pain (Visual Analogue Scale = 50-100). The patients presented at the Acute Pain Service (APS) section of the Second Department of Surgery, University of Cologne. Six of eight patients (75%) had no phantom limb pain after 10 days of intravenous treatment with salmon-calcitonin (maximum of five cycles of calcitonin infusion). Systematic follow-up examinations after 3, 6 and 12 months showed long-term success. Patient satisfaction was examined with a numeric rating scale (NRS 1-6) between the single infusion cycles. When patient satisfaction was low, the physician modified the time period or drug dosage between infusions. This study shows good or excellent results in patient satisfaction for six of eight patients (75%). A prospective randomized trial is required to verify the excellent results of intravenous salmon-calcitonin in a larger population. Alternative pharmacological and operative treatments of phantom limb pain are critically reviewed and assessed.

We report on a 29-year-old motorcyclist, who had suffered a traumatic right side arm plexus lesion. The myelo-CT image showed a avulsion of the cervical roots C7/C8. Five days after the accident the patient complained of phantom pain in the right plegic arm and was presented to our acute pain service (APS). The patient complained of lancinating attacks of severe phantom pain in the right arm (visual analogue scale intensity of 80-100 pts.). The initial pain treatment was performed with PCA (piritramide), and because of the lancinating pain character carbamazepine treatment was introduced. The pain intensity increased under carbamazepine (VAS = 100 pts.), and after treatment with five cycles of salmon-calcitonin infusion the pain intensity decreased (VAS = 10 pts). After withdrawal of the infusion therapy with salmon calcitonin the pain intensity increased up to VAS = 70 pts. TENS therapy five times per day showed no analgetic effect. We repeated the calcitonin-infusion therapy and after five i.v. cycles we continued with 200 I.U. salmon calcitonin intranasal per day. The initial phantompain intensity decreased (VAS = 40 pts.), but showed no long term analgesia. The additional psychological treatment with relaxation techniques (Jacobson/Bensen) showed the desired phantom pain relief. An interdisciplinary and multimodal cooperation between anesthesiologists, trauma surgeons, neurosurgeons and psychologists is needed for successful phantom pain treatment after traumatic brachial plexus lesion. Intravenous salmon calcitonin showed only short-term analgetic effect.
