title: The clinical neuropathology of spinal cord injury. A guide to the future.
abstract: The neuropathology of spinal cord injury (SCI) is reviewed in the light of clinical problems and as a guide to future research. The pathology of SCI in the acute stage suggests that the spinal cord may be partly preserved even in the most severe injuries. This finding emphasises the need for great care in roadside management. In the acute phase there are irreversible changes and possibly reversible changes which have not been adequately identified. Even a small percentage of nerve fibres escaping the initial injury would be of great benefit to the patient. In the subacute stage when transynaptic degeneration is proceeding there may also be associated functional changes leading to abnormal reflex activity. It is possible through an improved understanding of the neuropathology and neurophysiology of the isolated or partly isolated segments of the cord that new reflex connections may be stimulated to develop by artificial means. In the chronic stage there are well recognised complications such as osteoarthrosis with spinal stenosis, post-traumatic syringomyelia and traumatic nerve root neuroma formation, which may lead to clinical deterioration and which may be amenable to treatment. In a more theoretical sense it is possible that improved understanding of CNS plasticity and transplant neurobiology using recombinant DNA technology, grafting and 're-education' of the regenerated tissues may be rewarding in the longterm future. Although this outcome is entirely hypothetical at this stage basic research deserves great emphasis.
