We report the case of a patient affected by vertebral pain refractory to conventional analgesic therapy with a diagnosis of spondylolysthesis and also the affects of a misdiagnosed brucellar spondylodiscitis. The absence of a positive response to conventional analgesics, a suggestive medical history (epidemiologic data still show a high incidence of Brucella infections for the Province of Catania), radiological findings and microbiological tests led to the correct diagnosis of algic syndrome in a patient affected by brucellar spondylodiscitis with the concomitant presence of retroperitoneal muscular abscess, and a previously diagnosed spondylolysthesis. All symptoms improved after correct antibrucellar antibiotic therapy and surgical drainage of the retroperitoneal abscess. Vertebral pain is a relatively frequent symptom observed in Pain Medicine Services; in a zone in which Brucella infections may be considered endemic, neurobrucellosis must be considered highly probable in the differential diagnosis of several clinical pictures, including vertebral pain that could result from vertebral localization of Brucella infection. The role of the Pain Medicine Specialist is not only to treat the symptoms, but also to research and confirm the etiopathogenetic mechanisms before starting a correct treatment.

Aim: The aim of this study is to evaluate the safety and effectiveness of antalgic and functional results after interdisciplinary approach and treatment of vertebral compression fractures (VCF) with percutaneous balloon kyphoplasty (KP) by the pain medicine specialist., Methods: Between April and December 2004, after informed consent, 13 patients have been treated for a total amount of 15 KP. For L5 - T11 level spinal anesthesia was performed, above T11 local infiltration was used. The following parameters were recorded: intraoperative course, postoperative course, pain before and after treatment, vertebral height restoring and quality of life measuring on visual analogical scale (VAS) and quality of life questionnaire of the European Foundation for Osteoporosis (QUALEFFO) scale., Results: No complications or adverse events were recorded. VAS values for pain were 6.2+/-2.1 preKP vs 3.3+/-1.7 and 4.5+/-1.1 respectively postKP and at follow-up, with statistically significant differences. Vertebral heights were 53.5+/-16%, 71.2+/-21% and 68.1+/-13.5%, preKP, postKP and at follow-up respectively, with statistically significant differences, similarly to quality of life related parameters and QUALEFFO score., Conclusion: Back pain due to vertebral compression fractures is a quite frequent diagnosis for the pain medicine specialist; KP is a new technique showing an association of a low incidence of complications with a success rate, both on pain control and on vertebral height restoring. In our study, KP proved to be a safe technique with a high success rate, both for pain relief and for vertebral height restoring, with immediate results and important consequences on the patient's quality of life, physical and mental status, with a low incidence of complications due also to the choice of performing this procedure in locoregional anesthesia.
