Long-term results of surgical correction of Scheuermann’s kyphosis

Objective. To analyze long-term results of surgical correction kyphosis due to Scheuermann’s disease. Material and Methods. Design: retrospective cohort study. The study group included 43 patients (m/f ratio, 34/9). mean age was 19.1 (14–32) years; the postoperative follow-up 6 ± 10 (5–20) years. Two-stage surgery including discectomy interbody fusion followed by posterior conducted in 35 cases (Group A). Eight B) underwent only spinal fusion. following parameters were determined for each patient: thoracic (TK), lumbar lordosis (LL) (scoliotic deformity thoracic/thoracolumbar spine, if curve magnitude > 5°), sagittal vertical axis (SVA), stable vertebra (SSV), first lordotic (FLV), proximal junctional angle (PJA) distal (DJA). All measurements performed immediately before surgery, one week after at end period. answered SRS-24 questionnaire Results. Groups comparable terms gender patients, body mass index initial Cobb (p < 0.05). decreased from 77.8° 40.7° Group A 81.7° 41.6° B. loss 9.1° 6.0° groups B, respectively. remained normal during At implant density less than 1.2, 44.5° (54.7 %) 3.9°, respectively Proximal (PJK) detected 21 out (48.8 %). frequency PJK 45.4 % among whose upper 60 those not included. developed eight (47.8 17 with ≥ 50 13 (50.0 %. rate DJK development 39.5 lower instrumented (LIV) located 16 cases, 12 (75 them being diagnosed DJK.

According patient questionnaires, outcome score increases between immediate periods all domains 88.4 91.4 total. same applies answer question about consent treatment on conditions: positive answers increased 82 86 Conclusions. as a more difficult prolonged one, has no advantages over one-stage operation stability achieved effect.
