Emergency evaluation, diagnosis, and management of the most common incomplete spinal cord injury
A 72-year-old man trips on a curb, strikes his forehead, and walks into your department. His legs work. He cannot button his shirt.
His cervical CT is read as “degenerative changes, no acute fracture.”
The most common incomplete cord injury, in the fastest-growing trauma population
Why the hands, and why no fracture
An incomplete cervical cord injury with disproportionately greater weakness in the upper than the lower extremities, variable sensory loss, and variable bladder dysfunction.
Classically after hyperextension of a stenotic cervical spine, often without fracture or dislocation. Schneider 1954 Anderson 2015

| Definition | Source | Strength | Weakness |
|---|---|---|---|
| Descriptive: arms weaker than legs, sacral sparing, variable bladder | Schneider 1954 Schneider 1954 | Clinically intuitive | Not quantified; observer-dependent |
| LEMS − UEMS ≥ 10 motor points | Pouw 2010 Pouw 2010 | Reproducible, most used in research | Excludes milder or atypical cases |
| LEMS − UEMS ≥ 5 motor points | Badhiwala 2022 Badhiwala 2022 | Captures more patients | Different cohorts from the ≥ 10 studies |
| Any adult cervical SCI without fracture or dislocation | Avila & Hurlbert 2021 Avila 2021 | Separates stable from unstable spines | Ignores the neurological pattern |
| Central Cord Injury Scale / Central Cord Score | Hohl 2010; Ramey 2021 Hohl 2010 Ramey 2021 | Adds MRI and function for prognosis | Small derivation cohorts |
There is no consensus definition. Prognostic studies show that AIS grade predicts outcome better than the CCS label itself. Pouw 2011 Engel-Haber 2023
Most central cord patients are AIS C or D. Definitions per ISNCSCI 2019. Rupp 2021
A 68-year-old woman falls down three steps and has a laceration on her forehead. She walks into the department. Both hands are weak (grip 3/5) with burning paresthesia; legs are 5/5; perianal sensation is intact. Her cervical CT is reported as spondylosis without fracture. What is the next step?
CT finds the fracture. MRI finds the injury.
Flexion–extension radiographs have no role in the acute setting with a deficit.

Should this patient receive high-dose steroids?
| Study | Design | N | Comparison | Key finding | Limitation |
|---|---|---|---|---|---|
NASCIS II 1990 Bracken 1990 | RCT, 3 arms | 487 | MPSS 30 mg/kg + 5.4 mg/kg/h × 23 h vs naloxone vs placebo | No overall benefit; post-hoc: modest motor gain if given < 8 h | Subgroup analysis; small absolute effect |
NASCIS III 1997 Bracken 1997 | RCT | 499 | MPSS 24 h vs 48 h vs tirilazad | 48 h regimen: motor gain if started 3–8 h | No placebo; more sepsis and pneumonia with 48 h |
Cochrane (Bracken) 2012 Bracken 2012 | Systematic review | — | MPSS vs control | Modest motor benefit within 8 h | Authored by the NASCIS lead investigator |
Evaniew 2016 Evaniew 2016 | Meta-analysis, GRADE | 4 RCTs, 17 obs. | MPSS vs no steroid | No long-term motor benefit; ↑ GI bleeding in observational data | Low to very low confidence |
AANS/CNS 2013 Hurlbert 2013 | Guideline | — | — | Level I recommendation against MPSS | Criticised for over-reading harm data |
AOSpine 2017 Fehlings 2017 | Guideline | — | — | Suggest 24 h MPSS may be offered as an option if < 8 h; not after 8 h; never 48 h | Weak recommendation |
Any benefit is small, confined to the first 8 hours and rests on post-hoc analyses; harm signals include infection, hyperglycemia and GI bleeding, which weigh heavily in older patients.
Not a standard of care. Do not give steroids to a central cord patient presenting after 8 hours. Within 8 hours, follow your institutional protocol and the consulting surgeon; if used, it is the 24-hour regimen, never 48 hours.
Seventy years of controversy, and where the evidence stands in 2026
No randomized trial compares surgery with nonoperative care for central cord syndrome. These are consensus positions drawn from observational data and guidelines. Aarabi 2013 Yelamarthy 2019
Early (< 24 h) versus late surgery
| Study | Design | N | Comparison | Key finding | Limitation |
|---|---|---|---|---|---|
STASCIS 2012 Fehlings 2012 | Prospective cohort, all cervical SCI | 313 | < 24 h vs ≥ 24 h | ≥ 2-grade AIS gain 19.8% vs 8.8% (adj. OR 2.8) | Not randomised; 71% follow-up |
Lenehan 2010 Lenehan 2010 | Ambispective, stenotic CCS without instability | STSG database | < 24 h vs later | +6.3 motor points at 12 months | Observational; small effect |
Badhiwala 2021 Badhiwala 2021 | Pooled IPD, 4 prospective datasets | 1,548 | < 24 h vs ≥ 24 h | +4.0 motor points at 1 year; plateau after 24–36 h | All SCI, not CCS-specific |
Badhiwala 2022 Badhiwala 2022 | Propensity-matched CCS cohort | 186 | < 24 h vs ≥ 24 h | +2.3 UE motor points; AIS C +9.5 total; AIS D no difference | Younger cohort (mean 48); CCS defined as ≥ 5-point gap |
Aarabi 2021 Aarabi 2021 | Retrospective, stenotic CCS, MRI-confirmed decompression | 101 | ≤ 24 h vs 25–72 h vs > 72 h | No effect of timing; admission motor score predicted outcome | Single centre; AIS C/D only |
Sattari 2024 Sattari 2024 | Meta-analysis, CCS | 5,619 (9 studies) | < 24 h vs ≥ 24 h | +4.9 motor points at 1 year; fewer VTE and complications; shorter stay; no mortality difference | Observational inputs; moderate certainty |
Moderate-quality observational evidence that decompression within 24 hours improves motor recovery across SCI, with a smaller but consistent signal in central cord syndrome, concentrated in AIS C patients and those with structural compression. Some stenotic cohorts show no timing effect.
Treat a central cord patient with persistent compression and a meaningful deficit as time-sensitive: consult at diagnosis, resuscitate quickly, and aim for surgery within 24 hours when the patient is fit. AIS D patients with an improving examination can be observed.

| Guideline | Recommendation on timing | Evidence |
|---|---|---|
| AANS/CNS 2013 Aarabi 2013 | Early reduction of fracture-dislocation; early surgical decompression of the compressed cord | Level III |
| AOSpine 2017 Fehlings 2017 | “We suggest that early surgery be considered as a treatment option in adult patients with traumatic central cord syndrome” | Low |
| Spinal Cord Society / STSG 2019 Yelamarthy 2019 | Position statement favouring early surgery in selected patients with persistent compression | Systematic review |
| AO Spine / Praxis 2024 Fehlings 2024 | Early surgery (≤ 24 h) offered as the preferred option for adult acute SCI regardless of level; no recommendation on ultra-early surgery | Moderate (RR 2.76 for ≥ 2-grade AIS gain at 6 months; +4.5 motor points) |
The 2024 recommendation applies to acute SCI as a whole; the guideline does not carve out a separate rule for central cord syndrome.

A 61-year-old man falls from a ladder. Examination at 4 hours: UEMS 18, LEMS 38, sacral sparing present, most key muscles below the level are grade 2 (AIS C). CT: multilevel spondylosis, no fracture. MRI: C4–5 and C5–6 compression with T2 signal at C4–5, no ligamentous injury. He is hemodynamically stable. Which statement best reflects current evidence?
What to tell the patient and the family
Apply it

An 80-year-old woman with central cord syndrome after a fall (AIS D, stable spine, CT without fracture) arrives 11 hours after injury. Her family asks whether she should receive high-dose methylprednisolone. What do you tell them?
Time is spine, but the patient is more than the cord.
Recognise early, image the cord, perfuse it, call early, and treat the older adult as the whole and fragile person they are.
