Posterior spine fusion in a Jehovah's Witness patient with severe rigid idiopathic scoliosis - A case report.

Introduction: Early onset scoliosis (EOS) represent a challenge for spine surgeons. The selection of the best treatment is complex. Some patients, such as Jehovah's Witnesses who refuse blood transfusions, are at high risk of complication when surgical treatment is required because blood loss is a major cause of morbidity and postoperative transfusion rates. Research question: Describe blood-saving techniques that allowed an extensive and invasive surgical procedure in a Jehovah's Witness patient. Material and method: 17-year-old Jehovah's Witness girl with severe 120° Cobb Lenke 1A idiopathic scoliosis started as EOS was prepared with 4 cycles of recombinant human erythropoietin, iron and folic acid supplementation that brought her hemoglobin level from 13.6 g/dl to 16.2 g/dl. In the first surgical time, a temporary rod was implanted. Spine dissection using bipolar sealer and a special electrocautery that operates at lower temperatures than traditional ones was performed. Facetectomies and multilevel Ponte osteotomies was performed using an ultrasonic bone scalpel. The second surgical time, the definitive rods were placed, and the correction of the deformity was achieved using the rod link reducer technique. Results: A good correction of the main curve in the coronal plane is achieve. The Hb nadir was 7.2 g/dl four days after the second operation. The postoperative course was uneventful. Discussion and conclusion: The integration of modern and traditional preoperative, intraoperative, and postoperative blood sparing techniques allowed us to perform an extensive and invasive surgical procedure in a Jehovah's Witness girl with a severe idiopathic scoliosis.
