During the past war large numbers of patients with spinal cord injuries were seen on the neurosurgical services of the specialized general hospitals in the zone of the interior. These injuries were due to direct wounds from high explosive fragments or bullets, or to crushing injuries of the spine associated with violent trauma. With modern methods of therapy, the life span of these paralyzed individuals has been greatly lengthened. In the course of their treatment many complications developed. The commonest of these were malnutrition, decubitus sores, urinary tract calculi, and spastic deformities. The bony prominences adjacent to the decubiti frequently became eroded. In addition, ossifications developed in the neighboring soft tissues. These ossifications and erosions have been of particular interest to us. Following the First World War, Dejerine, Ceillier, and Dejerine (1, 2) observed the presence of ossifications in the soft tissues, chiefly around the joint capsules and femoral shafts, in 49 per cent of paraplegic patients and described them under the name of “para-osteo-arthropathies.” They called attention to the lack of development of disintegrative changes of the joint surfaces which commonly occur in the tabetic arthropathies and also pointed out that pathological fractures were very unusual. Erosions of bone adjacent to sores were noted but no descriptions were given. Voss (3) completely reviewed the literature in 1937 and called attention to the development of these ossifications in a variety of diseases of the brain, spinal cord, and peripheral nerves. He presented the following list of conditions in which soft-tissue ossifications had been observed: Brain Diseases and Cerebral Hemiplegia Epidemic encephalitis Progressive paralysis Syphilis of central nervous system Arteriosclerotic bleeding and thrombosis Embolic encephalitis Post-traumatic brain lesions Brain hemorrhage with intracranial hemangioma Cerebral hemiplegia of unknown etiology Diseases of the Spinal Cord Meningocele Traumatic section of cord Extramedullary tumor Myeloencephalitis Syphilitic meningomyelitis Tuberculous meningomyelitis Acute anterior poliomyelitis Funicular myelosis with circumscript thrombosis Tabes dorsalis Syringomyelia Diseases of the Cauda Equina Compression of the cauda equina Diseases of the Peripheral Nerves Polyneuritis Recently Soule (4) has described the findings in a group of 62 patients with disease of the spinal cord and cauda equina under the title “Neurogenic Ossifying Fibromyopathies.” Roentgenologists assigned to the large general hospitals caring for patients with spinal cord injuries had the opportunity of observing the soft-tissue ossifications and the erosive bone lesions. It seems timely, therefore, to present a description of the roentgen findings since the detection of these lesions is primarily roentgenologic.
