Predictive Markers in Decision-Making for Screwing the Fractured Thoracolumbar Vertebra in the Short-Segment...

Area of Science:

• Spine surgery
• Orthopedics
• Traumatology

Background:

• Spinal instrumentation aims to stabilize fractures and prevent collapse.
• Decision-making for screw placement in fractured vertebrae is crucial for optimal outcomes.
• Short-segment and long-segment instrumentation are common surgical techniques.

Purpose of the Study:

• To compare the long-term results of short-segment versus long-segment spinal instrumentation.
• To identify predictive markers for deciding whether to screw the fractured vertebra.

Main Methods:

• Retrospective study comparing two groups: short-segment (screwing fractured vertebra) and long-segment (skipping fractured vertebra) instrumentation.
• Analysis of preoperative and long-term follow-up data including fracture characteristics and patient outcomes.
• Logistic regression analysis to identify predictive markers.

Main Results:

• Both instrumentation methods demonstrated similar long-term effectiveness in preventing vertebral collapse.
• Preoperative differences between groups included pedicle fracture, AOSpine score, vertebral height, and spinal canal diameter.
• Logistic regression identified pedicle fracture, AOSpine score, adjacent vertebral height, and spinal canal diameter as significant predictive markers.

Conclusions:

• Short-segment and long-segment instrumentation yield comparable long-term outcomes.
• AOSpine Classification Scale score, pedicle fracture, adjacent vertebral height, and spinal canal diameter are valuable predictive markers.
• Patients with pedicle fractures, significant height loss below the fracture, or narrow spinal canals may not be suitable for direct screw fixation of the fractured vertebra.
