ABSTRACT
OBJECTIVES: To compare injury characteristics, demographics, and functional outcomes of patients with infection-related spinal cord disease (IR-SCD) vs. those with traumatic spinal cord injury (SCI). DESIGN: A 10-yr retrospective review of 34 consecutive patients with IR-SCD admitted to an SCI rehabilitation unit at a Level 1 tertiary university medical center. Outcome measures included length of stay (LOS), FIM motor scores, and home discharge rates. RESULTS: The cause of IR-SCD was most often spinal epidural abscess secondary to Staphylococcus aureus (74%). Weakness (90%) and neck/back pain (84%) were the most frequent initial admitting symptoms. Identifiable risk factors included history of recent infection (42%), diabetes mellitus (32%), and intravenous drug abuse (26%). SCD-related complications most commonly included pain (81%), urinary tract infection (52%), and spasticity (45%). When compared with traumatic SCI (n = 560), patients with IR-SCD comprised significantly less of the SCI/D rehabilitation admissions (3% vs. 61%), were older (53 vs. 40 yrs), and more often female (35% vs. 16%). Injuries were more commonly located in the thoracic region (48% vs. 38%). Patients with IR-SCD more often had incomplete injuries (94% vs. 57%). Thirty-two percent of IR-SCD patients had improvements in AIS impairment scale classification. LOS was longer on acute care (25 vs. 16 days), but similar on rehabilitation (36 vs. 34 days), and with lower FIM motor changes (16.2 vs. 22.8) during rehabilitation. Patients with IR-SCD were less often discharged to home (56% vs. 75%). CONCLUSIONS: Patients with infection-related SCD comprise a significant subset of SCI/D rehabilitation admissions and have differing demographic and injury characteristics compared with traumatic SCI. Despite less-severe injury characteristics and similar rehabilitation LOS, they achieve lower functional improvements and are less often discharged home, underscoring the importance of patient/family education and discharge planning.

BACKGROUND/OBJECTIVE: To examine and compare demographics and functional outcomes for individuals with spinal cord injury (SCI) clinical syndromes, including central cord (CCS), Brown-Sequard (BSS), anterior cord (ACS), posterior cord (PCS), cauda equina (CES), and conus medullaris (CMS). DESIGN: Retrospective review. SETTING: Tertiary care, level 1 trauma center inpatient rehabilitation unit. PARTICIPANTS: Eight hundred thirty-nine consecutive admissions with acute SCIs. MAIN OUTCOMES MEASURES: Functional independence measure (FIM), FIM subgroups (motor, self-care, sphincter control), length of stay (LOS), and discharge disposition. RESULTS: One hundred seventy-five patients (20.9%) were diagnosed with SCI clinical syndromes. CCS was the most common (44.0%), followed by CES (25.1%) and BSS (17.1%). Significant differences (P < or = 0.01) were found between groups with regard to age, race, etiology, total admission FIM, motor admission FIM, self-care admission and discharge FIM, and LOS. Statistical analysis between tetraplegic BSS and CCS revealed significant differences (P < or = 0.01) with respect to age (39.7 vs 53.2 years) and a trend toward significance (P < or = 0.05) with regard to self-care admission and discharge FIM. No significant differences (P < or = 0.01) were found when comparing CMS to CES. CONCLUSIONS: SCI clinical syndromes represent a significant proportion of admissions to acute SCI rehabilitation, with CCS presenting most commonly and representing the oldest age group with the lowest admission functional level of all SCI clinical syndromes. Patients with cervical BSS seem to achieve higher functional improvement by discharge compared with patients with CCS. Patients with CMS and CES exhibit similar functional outcomes. Patients with ACS and PCS show functional gains with inpatient rehabilitation, with patients with ACS displaying the longest LOS of the SCI clinical syndromes. These findings have important implications for the overall management and outcome of patients with SCI.
