Calcium Pyrophosphate Arthropathy of the Spine

Calcium pyrophosphate deposition disease is a relatively uncommon arthropathy characterized by the clinical features of pseudogout, the radiographic manifestations of chondrocalcinosis, and the pathological deposition of calcium pyrophosphate crystals in both hyaline and fibrocartilage. Symptomatic involvement of the spine by calcium pyrophosphate deposition disease is rare except by nodular deposition in the ligamentum flavum and atlanto-occipital ligament. We report a 50-year-old woman who presented with an acute herniated disc syndrome secondary to an intraspinal inflammatory calcium pyrophosphate deposition disease mass at the level of the L4-L5 interspace. The magnetic resonance image and histopathological features of the case are also discussed.

Pain, disability, and psychological functioning in chronic low back pain subgroups: myofascial versus herniated disc syndrome.

A series of patients with chronic low back pain evaluated at a tertiary referral center were the subjects for this study. Of 250 consecutive patients, 94 were diagnosed as having myofascial pain and 57 as having herniated disc syndrome. Before evaluation and diagnosis, all patients completed the McGill Pain Questionnaire, ratings of pain and disability, and the Symptom Checklist 90-R. Patients were also grouped on the basis of previous surgical history and workers' compensation benefits. Patients suffering from myofascial pain were significantly less likely to report periods of pain relief than patients with herniated disc syndrome. Those receiving workers' compensation benefits reported significantly greater levels of pain, disability, and psychological distress than those not receiving benefits, irrespective of diagnosis. Patients who underwent previous surgery did not differ significantly from those who never underwent surgery. All patients had elevated scores on the Somatization subscale of the Symptom Checklist 90-R. Patients with myofascial pain and workers' compensation benefits demonstrated the highest levels of somatization and phobia. These findings suggest that the effects of low back pain of myofascial origin have comparable, if not worse, consequences than disc herniation. These findings also reaffirm the importance of workers' compensation in understanding the differences in patients with chronic low back pain.

Lumbar intervertebral disc herniation in the young.

A survey of 37 young patients, 10 to 18 years of age, with lumbar intervertebral disc herniation is presented. Local physical findings and limitation in straight-leg raising are often more marked in the young than in adults, whereas pain may be slight or even absent. Neurological findings were normal in 40 per cent of the cases, and when deficits were found, they were usually of a minor nature. Herniated disc syndrome in children and adolescents is characteristic and should not be difficult to recognize. With surgical treatment good results were obtained in nearly all cases.

A Controlled Trial of Doloneurobion® in Low Back Pain

A controlled study was carried out to evaluate the efficacy of Doloneurobion ampoules and tablets in the treatment of patients suffering from ‘low back pain’ due to herniated disc syndrome, narrowed spinal canal and other causes. Fifty patients received treatment with both the parenteral and oral presentation of Doloneurobion during an average treatment period of three weeks. Twenty patients with similar symptoms acted as a control group and received physical treatment only. Doloneurobion produced significantly better results (p < 0·05) than the control group using the parameters of ‘pain', ‘parasthesiae’ and scoliosis. No undue side-effects were noted during the study.

HERNIATED INTERVERTEBRAL LUMBAR DISC IN THE TEENAGER

1. Of 456 patients with features of herniated intervertebral disc eight were under twenty years of age. 2. Differences in the pattern of clinical presentation of the herniated disc syndrome in adults and in adolescents are discussed. 3. Whereas in the adult conservative treatment is usually successful, this is not so in the adolescent, in whom the symptoms and signs tend to persist for many months. 4. It is suggested that in the adolescent conservative treatment should not be prolonged despite the absence of neurological deficit; operation should be undertaken early after confirmation of the diagnosis by myelography.

Chronic lumbar extradural haematoma simulating disc syndrome.

Two patients presenting with a clinical picture of nerve root compression suggestive of the herniated disc syndrome are reported. In both the diagnosis proved to be chronic encapsulated extradural haematoma. Recognition of this entity at the time of surgical exposure should render the surgical dissection easier. The postoperative results in both were excellent. One of these patients was on chronic anticoagulant therapy and the unusual location and good prognosis of extradural haematoma in the lumbar spinal canal in such patients is emphasized. In the other, the haematoma developed after a minor back injury, which introduces medico-legal implications.
