Sequential Correction versus Conventional Correction for Severe and Rigid Kyphoscoliosis: A Retrospective Case...

Area of Science:

• Spine surgery
• Orthopedics
• Surgical techniques

Background:

• Severe and rigid kyphoscoliosis correction is challenging with conventional methods, posing risks of neurological complications.
• A novel technique, sequential correction, has been developed for treating severe and rigid kyphoscoliosis.

Purpose of the Study:

• To compare the clinical outcomes of sequential correction versus conventional correction for severe and rigid kyphoscoliosis in adults.
• To evaluate the safety and efficacy of sequential correction in this patient population.

Main Methods:

• A case-control study included 36 adults with severe and rigid kyphoscoliosis (20 conventional, 16 sequential correction).
• Key metrics included major curve Cobb angle, kyphotic angle, coronal imbalance, and sagittal vertical axis.
• Patient-reported outcomes (Oswestry Disability Index, SRS-22) and complication rates were assessed.

Main Results:

• Both techniques significantly improved major curve Cobb and kyphotic angles, with no significant differences between groups.
• Patient-reported quality of life scores improved similarly in both groups postoperatively.
• The sequential correction group had a slightly lower total complication rate (43.75%) compared to the conventional group (55%).

Conclusions:

• Sequential correction is an excellent and safe treatment option for severe and rigid kyphoscoliosis in adults.
• Clinical outcomes of sequential correction are comparable to conventional correction.
• Sequential correction may offer a slightly reduced complication rate.
