Abstract

Purpose: Compare radiographic outcomes, complications, and QoL in neuromuscular early-onset scoliosis (EOS) patients treated with single posterior spinal fusion (PSF) versus growth-friendly surgery and definitive fusion (GFDF). Methods: In a retrospective cohort study, children with neuromuscular EOS, age 8–11 years at index surgery with PSF or GF devices, with minimum 2-year follow-up after final fusion were identified from a multicenter database. Results: 16 PSF and 43 GFDF patients were analyzed. Demographics were similar except PSF patients were older at index surgery and had shorter follow-up. PSF patients had greater percentage major curve correction (62% vs 38%, p = 0.001) and smaller major curve at final follow-up (23° vs 40°, p = 0.005). The GFDF group underwent over five times more surgeries (8.7 vs 1.6, p = 0.0001). Four PSF patients (25%) experienced ten complications, resulting in five unplanned returns to the operating room (UPROR) in three patients (19%). 36 GFDF patients (84%) experienced 83 complications, resulting in 45 UPRORs in 24 patients (56%). Poisson regression adjusted for age showed that the GFDF group had more complications (p = 0.001) and UPRORs (p = 0.01). Although the GFDF patients had smaller preoperative T1–T12 and T1–S1 lengths, these were similar to the PSF patients at final follow-up, indicating that the GFDF patients had greater spinal growth. PSF patients had better postoperative EOSQ-24 Financial Impact and Family Burden scores. Conclusion: While there was a difference in age at index surgery, PSF may be more effective than GFDF at controlling neuromuscular EOS. GFDF patients achieved more spinal growth but eight times more complications and nine times more UPRORs.
