Electrical stimulation for idiopathic scoliosis.

To evaluate the effectiveness of lateral electrical spinal stimulation for idiopathic scoliosis, 87 patients treated with this modality were reviewed retrospectively. All patients had no prior treatment, had a documented progression of more than 5 degrees, and were skeletally immature. Forty-seven patients were compliant and followed until skeletal maturity or institution of other treatment. Fifty percent of patients with a high probability of progression required surgery. For compliant patients, 51% progressed 5 degrees or more and 36% progressed 10 degrees or more or required a change to another treatment modality. Statistical analysis demonstrated no significant difference in the probability of progression between this group of treated patients and previously published groups of untreated patients.

Low back pain.

Low back pain probably always will be a problem because of the anatomic arrangement of the lower spine and posture in standing and walking. However, during recent years, new attempts at diagnosis and treatment of this difficult problem have occurred, and it is now possible, in most cases, with a good history, physical examination, and diagnostic work-up to determine the cause of the problem. The injuries are still difficult to treat in many cases, but often with a thorough explanation to the patient about the underlying problem and mechanism of pain, and with use of the "back school" and conservative measures, most of the patients can continue on with daily activities. Formal surgery is playing less of a role in the treatment of back problems, with the development of various injections and percutaneous techniques. Still to be addressed, and where considerable effort and energy should be spent, is in the prevention of back problems with changes in daily habits and in increased awareness of ways to avoid back injuries.

CT myelography in cervical nerve root avulsion.

Computed tomographic myelography (CTM) with metrizamide was performed in six patients to delineate the CTM appearance of avulsed cervical nerve roots. Twelve cervical nerve root avulsions were found and confirmed by cervical myelography and physical examination. The CTM findings in cervical nerve root avulsion closely matched those found myelographically: outpouchings of metrizamide extending ventrolaterally from the thecal sac into the neural foramen in an expanding or "mushroom-like" manner and separated from the thecal sac proximally by a 1-2 mm thick dural plane. This CTM appearance differs from that seen in such normal variants as dilated nerve root sleeves or root diverticula. We conclude that CTM is as sensitive as myelography. In addition, it can provide useful information regarding bony fragments or contiguous soft tissue injury.
