Abstract
Aims
Cauda equina syndrome (CES) is a rare condition which requires urgent treatment to reduce the risk of long term neurological morbidity. Most authors recommend surgical decompression within 24–48 hours of the onset of symptoms, which may not be possible if there are delays in referral to hospital, performance of diagnostic imaging or poor access to a spine surgeon. We present a snap shot of referrals of patients with suspected cauda equina syndrome to the Orthopaedic department in a district general hospital including the diagnoses, management and outcome.
Methods
A retrospective review of 20 consecutive patients (mean age 49, 11 males, 9 females) referred via Primary Care to the orthopaedic on call team between April and December 2010 was carried out. Data were recorded including the clinical symptoms and signs on admission, time taken to undergo MRI, diagnosis and treatment.
Results
18/20 patients had red flag symptoms. Two patients with convincing neurological evidence of CES were transferred to the local neurosurgical unit for urgent assessment and surgical intervention. 12 patients required urgent inpatient MRI scans; mean time to MRI for these patients was 22 hours from the initial Orthopaedic assessment. Of these, none showed cauda equina and 3 were offered elective surgery for spinal nerve root compression. 14 out of 20 patients presented outside normal working hours when immediate access to MRI was unavailable.
Conclusions
The majority of patients in this study had red flag symptoms, although few actually had CES. Usually patients present in the evening when access to MRI is unavailable, potentially delaying the diagnosis. Such information may be useful to radiology departments to help plan out of hours services or help district hospital Orthopaedic departments develop protocols with nearby neurosurgical units for rapid patient transfer when CES is suspected.
