Background: Although several studies were performed to measure stiffness-related functional disability (SRFD) after long segmental fusion for adult spinal deformity, the evaluation of SRFD was done at a single point in time. We do not know whether the disability will stay the same, worsen, or improve over time.
Objective: To evaluate the time-dependent changes of SRFD and any factors affecting these changes.
Background: Corrective osteotomy is an effective surgery for correcting posture in patients with ankylosing spondylitis (AS). Despite satisfactory correction, some patients experience re-stooping during follow-up. However, there have been no studies on re-stooping in AS.

Methods: We performed a retrospective study of patients who underwent surgical treatment for metastatic spinal tumors between 1996 and 2020. For trend analysis, the study cohort was divided into three groups according to the year of surgery: 1996-2004, 2005-2012, and 2013-2020.
Background: In general, stiffness-related functional disability (SRFD) is expected to increase as longer fusion length, but there have been no studies on factors affecting SRFD besides fusion length.
Objective: To identify the factors affecting SRFD after long segmental fusion in patients with adult spinal deformity (ASD).
Methods: We retrospectively reviewed the patients who underwent ≥4-segment fusion including sacrum for ASD.
Study Design: Retrospective study.
Objective: To validate the age-adjusted ideal sagittal alignment in terms of proximal junctional failure (PJF) and clinical outcomes.
Summary Of Background: It is reported that optimal sagittal correction with regard to the age-adjusted ideal sagittal alignment reduces the risk of PJF development.
Objective: Score on the proximal junctional kyphosis severity scale (PJKSS) has been validated to show good correlations with likelihood of revision surgery for proximal junctional failure (PJF) after surgical treatment of adult spinal deformity (ASD). However, if the patient has progressive neurological deterioration, revision surgery should be considered regardless of severity based on PJKSS score. This study aimed to revalidate the correlation of PJKSS score with likelihood of revision surgery in patients with PJF but without neurological deficit.

Methods: Thirty-one THR patients were enrolled. The patients were categorized into two groups: fracture group (n=15) and non-fracture group (n=16).
Background: The aim of the present study was to identify the clinical and radiologic factors affecting functional outcomes in patients with a distal radius fractures (DRFs) treated by volar locking plate fixation.
Patients And Methods: Prospective cohort of patients with dorsally angulated DRFs requiring the volar locking plate fixation were recruited during one year. We evaluated wrist motion, grip strength, and DASH score at 3, 6 and 12 months after surgery.
