INTRODUCTION
THE EVIDENCE
The Lay Evidence
"Ambulance admission. Road traffic collision – combined speed? Patient rear seat passenger. Lap belt in situ. Complaining of pain in abdomen. 10mgs oral morphine given in ambulance to good effect. Learning disabilities"
Documentary Evidence
"(i) The ambulance crew notified the emergency department of the impending arrival of six patients from a road traffic accident, four or whom were young adults with learning difficulties.
(ii) The ambulance staff were not concerned about the clinical condition of any of them and therefore no trauma call was instigated.
(iii) The staff in the emergency department all commented that with hindsight a trauma call should have been initiated and if it had been, felt that XXX would have been assessed more quickly after her arrival. Staff were unclear about the guidelines for instigating trauma call, the guidelines were not on display in the department but they were available on all computers in the department.
(iv) The trauma guidelines state that a trauma call should be instigated if there are symptoms or signs of neck or other spinal fractures (e.g. paresis). However, the numbness in XXX's proximal femur documented by the ambulance crew was not thought to be related to a spinal injury and this was the only trigger that matched the trauma call guidelines.
(v) Of the five other patients admitted following the accident, four were discharged home the same day. One, who complained of a wrist injury and right knee pain was admitted.
(vi) The on-call consultant for emergency medicine said that the guidelines for initiating a trauma call were available in the department but their use is "often down to the discretion of the nurse in charge of the department. He thought a trauma call had been initiated for this road traffic accident, but on reflection accepts it has not".
"Review of her Yeovil admission shows that the RTA was approximately 9.30 this morning. She arrived at Yeovil A&E at 10.20 and had a CT scan. Interestingly, (XXX's) parents say she complained of some pain when she was sat up in the Yeovil A&E and her legs hung over the side of the bed. Since then she has been lying flat and has been log-rolled"
The Expert Evidence
The Emergency Medicine Experts Joint Report
i) a trauma call should result in a primary survey of the patient by a doctor within a few minutes, assessing for any abnormalities affecting the airway, breathing and circulation, a brief assessment of conscious level and pupil reactions of the patient, followed by a secondary survey consisting of a top to toe systematic examination for injuries, including the spine.
ii) the spine would be examined by log-rolling once the pelvis had been cleared of significant injury.
iii) in 2011, routine x-rays of the cervical spine, chest and pelvis would be performed together with routine blood tests as part of the primary survey. The experts note that Dr Irbash assessed XXX using a primary/secondary survey approach once he had been asked to see her because of her changed neurological symptoms.
iv) it was apparent that the emergency department ("ED") staff were aware that XXX had signs of a seat belt injury (bruising, redness and/or abrasions following the pattern of the seat belt), that the information available on arrival at the ED that XXX had been wearing a lap seatbelt together with the seatbelt signs pointed towards possible injury underlying the site of the belt, that XXX ought to have been immobilised if she could tolerate immobilisation; otherwise she would have been encouraged to lie still; and she should be log-rolled for any examination of the back.
v) that management should have commenced once XXX had been handed over to the ED staff by the ambulance crew.
The Neuro-radiology Experts Joint Report
i) the imaging disclosed an unstable fracture dislocation at T12/L1 level with bilateral facet dislocation.ii) the fracture dislocation probably occurred at the time of the accident;
iii) it was a locked fracture dislocation, involving the superior end plate and transverse process of L1.
iv) on the limited imaging sequences available, without specific sequences to detect blood, there was no evidence of bleeding within the spinal cord; but that small anterior and posterior epidural collections of serosanguinous material were present.
The Neurology, Neurosurgery and Spinal Injuries Experts Joint Report
(i) in addition to the fracture, there was dislocation of the spine, due to disruption of the facets, leading to spinal malalignment at the injured level (referred to as 'translation'). That amounted to a type C fracture, (the most severe class of such fractures);
(ii) XXX was at the severe end of the spectrum for these fractures, because the facets had dislocated and locked. The degree of anterior translation equated to approximately 50%;
(iii) there was a fracture to the superior end-plate at T12 anteriorly. However, the most significant component of the injury was the facet dislocation with locking of the facets resulting in spinal malalignment/ translational deformity with kyphosis.
(iv) the majority of patients who sustain an injury of this type of fracture will also suffer a spinal cord injury;
(v) the purpose of spinal precautions is to reduce the chance of additional spinal cord injury in a patient who has already suffered an unstable spinal injury. A paramedic attending a trauma patient does not know whether or not a patient has sustained a spinal injury, and therefore adopts spinal precautions when there is suspicion of spinal cord injury, either clinically, or from the injury mechanism, or both.
(vi) these are four mechanisms of spinal cord injury following an unstable spinal injury, namely mechanical damage and compression of the spinal cord; disruption of the blood supply; inflammation; and a combination of the above.
(vii) a supraphysiological/pathological force is required to cause a fracture.
(viii) a greater force is required to dislocate the facets than to cause a fracture alone.
(ix) On the spectrum of stable versus unstable injuries, this was at the severe end of instability, given that the T11 vertebral body had translated so far anteriorly that the facet joints had dislocated and locked;
(x) the fact that the fracture-dislocation occurred at impact meant that the spinal canal was narrowed and the spinal cord would have been compromised from the outset;
(xi) the spinal cord would have been compromised to some degree at impact. The experts could not agree as to the extent of the compromise. None of them felt that XXX would have had normal power in her lower limbs after the accident;
(xii) a factual finding that, on admission, XXX assisted a nurse to undress her by raising her bottom from the bed and pushed her feet against the nurse's hand, did not imply an intact spinal cord. It implied that there was still some spinal cord function, which was still capable of supporting voluntary movement in the legs; and
(xiii) a clinically/radiologically transected spinal cord is to be regarded as a complete spinal cord injury.
