Correction of Scheuermann kyphosis: comparative study of hybrid fixation using hooks and screws versus screw-only fixation

OBJECTIVE: to evaluate the degree of correction of Sheuermann kyphosis, in 6 patients who were submitted to surgery using hybrid instrumentation comprised of hooks and screws (H), and 17 patients undergoing screw-only fixation (P). METHODS: 23 patients with Scheuermann kyphosis were submitted to surgical treatment using anterior and posterior approach. In the present study, we indicated surgical treatment for rigid kyphosis, varying between 60º and 105º. All patients presented a Risser signal above 4. Liberation and Fusion were realized through anterior approach, followed by fixation, deformity correction, and arthrodesis through posterior approach. RESULTS: in Group H, a preoperative kyphosis of 84.17º and a postoperative of 47.5º were observed. In Group P, a preoperative kyphosis of 80.35º and postoperative of 33.53º were observed. CONCLUSION: it was concluded that both types of fixation presented very satisfactory results, with screw only fixation being superior.
