摘要
Study Design. Retrospective review. Objectives. To report the feasibility safety and utility of vertebral body stapling without fusion as an alternative treatment of adolescent idiopathic scoliosis. Summary of Background Data. The success rate of brace treatment of adolescent idiopathic scoliosis ranges from 50% to 82%. However, poor self image and brace compliance are issues for the patient. An alternative method of treatment such as a motion preserving vertebral body stapling to provide curve stability would be desirable. Methods. We retrospectively reviewed 21 patients (27 curves) with adolescent idiopathic scoliosis treated with vertebral body stabling. Patients were immature as defined by Rissner sign less than or equal to2. Results. The concept of vertebral body stabling of the convex side of a patient with adolescent idiopathic scoliosis is feasible. The procedure was safe, with no major complication sand three minor complications. One patient had an intraoperative segmental vein bleed resulting in an increased estimated blood loss of 1500 cc as compared to the average estimated blood loss of 247 cc for all patients. One patient had a chylothorax and one pancreatitis. No patient has had a staple dislodge or move during the follow-up period (mean 11 months range 3-36 months) and no adverse effects specifically from the staples have been identified. Utility (defined as curve stability) was evaluated in 10 patients with stapling with greater than 1-year follow up (mean 22.6 months) and preoperative curve <50%. Progression of ≥6° or beyond 50° was considered a failure of treatment. Of these 10 patients, 6 (60%) remained stable or improved and 4 (40%) progressed. One of 10 (10%) in the stabling group had progressed beyond 50% and went on to fusion. Six patients required stapling of a second curve three as part of the primary surgery, and three as a second stage, because a second untreated curve progressed. The results need to be considered with caution, as the follow-up is still short. Conclusions. The data demonstrate that vertebral body stapling for the treatment of scoliosis in the adolescent was feasible and safe in this group of 21 patients in the short term, stapling appears to have utility in stabilizing curves of progressive adolescent idiopathic scoliosis.
