Abstract

Standaert CJ, Herring SA. Expert opinion and controversies in sports and musculoskeletal medicine: the diagnosis and treatment of spondylolysis in adolescent athletes.

Although spondylolysis is relatively common in adolescent athletes, there are substantial disagreements in the literature concerning the best methods for diagnosing and treating the condition. Controversy particularly arises regarding the optimal use of available imaging modalities in the diagnosis of athletes with suspected pars defects and the extent of activity restriction or brace use required for appropriate treatment. Because there have been no controlled trials on the treatment of spondylolysis and only a very limited number of studies addressing potential imaging strategies, it is difficult to develop true evidence-based guidelines for this condition. Given the current state of the literature, it is our impression that nuclear imaging with single photon emission computed tomography followed by computed tomography, with a limited role for plain radiography, remains the standard for appropriately diagnosing a symptomatic pars lesion. Treatment hinges on activity restriction for an amount of time adequate to allow for symptom resolution and, when possible, potential bony healing followed by a progressive sport-specific rehabilitation program. The biomechanic effects of brace use in this population are not well understood, but there may be some detrimental effects to the use of a brace and there currently is no evidence that the routine use of a rigid brace results in any significant improvement in radiographic or functional outcome.

Diagnosis

Some authors advocate CT alone, nuclear imaging (specifically SPECT) followed by CT, or MRI as either the first line or definitive diagnostic approach.2, 6, 7, 8, 9 There is also disagreement on the type of diagnostic data needed to optimize treatment.2, 7, 9 Few studies have compared all of the available imaging modalities.

Treatment

The medical literature describes widely divergent approaches to treatment. Although almost all include a component of rest from aggravating activities, there are substantial

Conclusions

We have presented our opinions on how to best manage athletes with suspected lesions of the pars. Further study of this problem is clearly needed to establish more stringent evidence-based guidelines. Other interpretations of the available data are clearly possible.
