Facet Fracture ICD-9
Facet Fracture Etiology / Epidemiology / Natural History
- Common, generally involve the superior facet.
Facet Fracture Anatomy
Facet Fracture Clinical Evaluation
- Palpate entire spine for tenderness / step off.
- Complete neuro exam: motor strength, pin-prick sensation, reflexes, cranial nerves, rectal examination (perineal pin-prick sensation, sphincter tone, volitional spincter control)
- Absence of the bulbocaverosus reflex indicates spinal shock. Level of spinal injury can not be determined until bulbocaverosus reflex has returned.
- See ASIA form.
Facet Fracture Xray / Diagnositc Tests
Facet Fracture Classification / Treatment
- Unilateral, Nondisplaced, no subluxation: orthosis for 6-12 weeks.
- Unilateral, >40% of lateral mass height, or with associated discoligamentous disruption: are unstable. Treatment = fusion
- Bilateral: unstable. Treatment = fusion
- Floating lateral mass fracture: lamina and ipsilateral pedicle of the same segment are fractured, assoicated with radiculopathy. Treatment = fusion
