Fifty-two patients with Luque instrumentation wore reviewed for spinal deformities. Forty-two patients were reviewed during 1 year ] I unrest 7, 2 years I at follow-up. Two patients were included who lost correction within 1 year (both e months). Follow up averaged 2.9 years. Curve causes primarily were neuromuscular but included ore was caused by idiopathic scollofils, four by Scheuermann's disease, and 1 by post-laminectomy kyphosis. The Cobb angle progressed In 45^ of patients postoperatively. Factors contributing to progression Included progressive vertebral rotation or the crankshaft phenomenon |11), wire pull out (71, progressive pelvic obliquity (4), rod bending (31, psaudarlhrcsis <21, and rod migration (2). Factors correlating with progression were kyphosis, postoperative curve > 35® prooperative curve > 60*, and not fusing tD the pelvis In nonambulators. Crankshaft was common in patients Risoer II or less but did not occur in more mature patients.
