Trans-intervertebral space osteotomy for post-traumatic thoracolumbar kyphosis: a minimum 2-year follow-up study

Area of Science:

• Spine surgery
• Orthopedics
• Traumatology

Background:

• Post-traumatic thoracolumbar kyphosis (PTK) presents significant challenges in spinal deformity correction.
• Evaluating surgical techniques for PTK is crucial for improving patient outcomes.

Purpose of the Study:

• To assess the radiographic results and clinical efficacy of trans-intervertebral space osteotomy (TIO) for treating PTK.
• To analyze spinal-pelvic sagittal parameters and patient-reported outcomes after TIO.

Main Methods:

• Retrospective cohort study of 38 PTK patients treated with TIO.
• Analysis of spinal-pelvic sagittal parameters (TK, TLK, LL, FK, PI, PT, SS, SVA) and clinical scores (VAS, ODI).
• Evaluation of perioperative and follow-up complications.

Main Results:

• Significant improvements observed in thoracic kyphosis (TK), thoracolumbar kyphosis (TLK), lumbar lordosis (LL), focal kyphosis (FK), and sagittal vertical axis (SVA) (p < 0.05).
• Marked reduction in Visual Analog Score (VAS) and Oswestry Disability Index (ODI) (p < 0.05).
• Successful fusion achieved in all cases with no major complications.

Conclusions:

• Trans-intervertebral space osteotomy (TIO) is an effective treatment for post-traumatic thoracolumbar kyphosis (PTK).
• TIO leads to satisfactory correction of spinal deformity and favorable clinical outcomes.
• The procedure demonstrates successful fusion rates and a low complication profile.
