      Who Underwent Corrective Long Spinal Fusion for Adult Spinal Deformity.

AB  - STUDY DESIGN: Retrospective observational study. BACKGROUND: The risk of a 
      femoral neck fracture due to a fall after adult spinal deformity surgery has been 
      reported. One of the most significant factors among walking and balance tests in 
      post-operative ASD patients was the timed up-and-go test (TUG). This study aims 
      to calculate the minimal clinically important difference (MCID) in balance tests 
      after ASD surgery. METHODS: Forty-eight patients, 4 males and 44 females, were 
      included by exclusion criteria in 66 consecutive patients who underwent 
      corrective surgery as a treatment for ASD at our institution from June 2017 to 
      February 2022. The inclusion criteria for this study were age >/=50 years; and no 
      history of high-energy trauma. The exclusion criteria were dementia, severe 
      deformity of the lower extremities, severe knee or hip osteoarthritis, history of 
      central nervous system disorders, cancer, and motor severe paralysis leading to 
      gait disorders. The surgeries were performed in two stages, first, the oblique 
      lumber interbody fusion (OLIF) L1 to L5 (or S1), and second, the posterior 
      corrective fusion basically from T10 to pelvis. For outcome assessment, 10 m walk 
      velocity, TUG, ODI, and spinopelvic parameters were used. RESULTS: Ten meter walk 
      velocity of pre-operation and post-operation were 1.0 +/- 0.3 m/s and 1.2 +/- 0.2 
      m/s, respectively (p < 0.01). The TUG of pre-operation and post-operation were 
      12.1 +/- 3.7 s and 9.7 +/- 2.2 s, respectively (p < 0.01). The ODI improved from 38.6 
      +/- 12.8% to 24.2 +/- 15.9% after surgery (p < 0.01). All post-operative parameters 
      except PI obtained statistically significant improvement after surgery. 
      CONCLUSIONS: This is the first report of MCID of the 10 m walk velocity and TUG 
      after ASD surgery. Ten meter walk velocity and the TUG improved after surgery; 
      their improvement values were correlated with the ODI. MCID using the 
      anchor-based approach for 10 m walk velocity and the TUG were 0.10 m/s and 2.0 s, 
      respectively. These MCID values may be useful for rehabilitation after ASD 
      surgery.
