THURSDAY, Nov. 10 (HealthDay News) -- Minimally invasive excision of osteoid osteoma in the mobile spine is emerging as an alternative method to conventional surgery, according to a study published in the Nov. 15 issue of Spine.
Alessandro Gasbarrini, M.D., from the Rizzoli Institute in Bologna, Italy, and colleagues compared the benefits and disadvantages of conventional versus minimally invasive surgical techniques for osteoid osteoma of the mobile spine. Conventional intralesional excision of osteoid osteoma or a minimally invasive approach (video assisted endoscopy, microscope, or percutaneous radiofrequency coagulation) was performed by the same surgical team in 81 patients. Clinical features, radiologic findings, outcomes, complications, and local recurrences were assessed. Participants were scored for pain and neurologic symptoms before and after surgery, and at follow-up.
The investigators found that all patients experienced immediate pain relief after surgery. Neurologic impairment before treatment was found in one patient, who became neurologically symptom free postoperatively. Four patients had five local recurrences always associated with pain, all of which underwent additional surgeries. One patient developed a pneumothorax and another patient developed a hematoma. No cases of kyphosis or scoliosis were seen after surgery.
"Conventional excision therapy is an effective and reliable treatment for osteoid osteoma, associated [with] low morbidity and low local recurrence rate," the authors write. "Minimally invasive surgery is emerging as an alternative method, reducing soft tissue trauma and the collateral damage caused by a traditional surgical approach, [to] allow patients a more rapid and complete return to normal function."
