Table 1 Risk factors and mitigation strategies for screw loosening
Risk factor
Mitigation strategy
Low bone density (HU < 110)HU/VBQ-based screening, cement augmentation, coated screws
Long posterior constructUse intermediate screws, consider short-segment fixation
Multilevel decompressionAugment anterior column, limit construct length
Osteoporotic boneExpandable/fenestrated screws, nanocoated implants, PMMA augmentation
Traumatic disc injuryAssess via MRI, consider anterior support to maintain correction
Fracture at thoracolumbar junctionBiomechanical modeling, optimized trajectory selection
