The value of magnetic resonance imaging of the lumbar spine to predict low-back pain in asymptomatic subjects : a seven-year follow-up study.
In 1989, a group of sixty-seven asymptomatic individuals with no history of back pain underwent magnetic resonance imaging of the lumbar spine. Twenty-one subjects (31%) had an identifiable abnormality of a disc or of the spinal canal. In the current study, we investigated whether the findings on the scans of the lumbar spine that had been made in 1989 predicted the development of low-back pain in these asymptomatic subjects. ⋯ The findings on magnetic resonance scans were not predictive of the development or duration of low-back pain. Individuals with the longest duration of low-back pain did not have the greatest degree of anatomical abnormality on the original, 1989 scans. Clinical correlation is essential to determine the importance of abnormalities on magnetic resonance images.

Comparative StudyLong-term results of treatment of fractures of the medial humeral epicondyle in children.
The treatment of isolated, displaced fractures of the medial humeral epicondyle in children is controversial. Both plaster cast immobilization without reduction and open reduction and internal fixation have been advocated. The purpose of this long-term retrospective study was to analyze the functional and radiographic results of both nonsurgical and surgical management of these injuries. ⋯ In our study, nonsurgical treatment of isolated fractures of the medial humeral epicondyle with between 5 and 15 mm of displacement yielded good long-term results similar to those obtained with open reduction and internal fixation. The nonunion of the epicondylar fragment that was present in most patients who had been treated only with a cast did not adversely affect the functional results. Surgical excision of the medial epicondylar fragment should be avoided because the long-term results are poor.
