Conservative treatment of spondylolysis involving exercise initiated early and sports activities resumed with a lumbar-sacral brace.

Abstract

BACKGROUND:

Conservative treatment including the use of a brace and cessation of sports activities is known to be effective in spondylolysis. However, there is some controversy regarding [1] the type of brace, and [2] the endpoint for bracing, and [3] the timing of resumption of sports activities. The aim of the current study was to investigate the appropriateness of early exercise and resumption of sports activities with a lumbar-sacral brace in very early- and early-stage lumbar spondylolysis.

METHODS:

This prospective cohort study enrolled 45 patients with very early- and early-stage lumbar spondylolysis. A lumbar-sacral brace, structured to be a hard brace in the back and a mesh brace in the front, was used. Isometric exercises/stretching was started immediately after the initial visit. The number of patients for whom bone fusion was fully achieved on CT and the disappearance of signal intensity change on MRI were investigated.

RESULTS:

In 12 cases of very early-stage spondylolysis, the average elapsed time until signal intensity disappearance as confirmed on MRI was 4.3 ± 1.6 months. Bony union on CT was confirmed in all cases. In 33 cases of early spondylolysis, signal intensity change disappeared on MRI within 5.2 ± 2.4 months. The rate of bony union was 94.3%, and the average period required to achieve bony union observable on CT was 3.7 ± 1.0 months.

CONCLUSIONS:

Sufficient bony union can be achieved by conservative treatment with early exercise and a lumbar-sacral brace in cases of very early and early spondylolysis.
