ABSTRACT
We studied, retrospectively, 131 patients who had undergone an open operation for the carpal tunnel syndrome (CTS) in 229 hands. The symptoms were present on both sides in 59% of patients when first seen. Neurophysiological impairment of the median nerve was observed in 66% of the asymptomatic hands, and 73% of patients in this group developed symptoms of CTS after the opposite side had been operated on. Follow-up of patients with unilateral CTS showed that the subsequent development of disease in the unaffected hand is very common. We conclude that CTS is a bilateral disorder and that it becomes more evident as time passes. There is a correlation between the duration of symptoms and bilateral occurrence.

This case report concerns a 5-year-old boy who had intervertebral disc calcification with involvement of two disc spaces and herniation of nucleus pulposus in one. The patient's symptoms resolved completely in a week with conservative measures. At the 4-year follow-up, the child was symptom-free and in full health, the herniation of nucleus pulposus had resolved completely, and calcification had disappeared in one of the disc spaces. Although the cause of this disorder is uncertain, the course is benign and self-limiting, it seldom requires surgical intervention, and the natural history is one of resolution and complete resorption of the calcification.
