Prospective Comparison of Patient-selected Operative Versus Nonoperative Treatment of Scheuermann Kyphosis.

BACKGROUND

Scheuermann kyphosis (SK) can be managed operatively or nonoperatively. Few studies compare the effect of operative versus nonoperative treatment on patient health-related quality of life. We compare 2-year radiographic and the Scoliosis Research Society-22 questionnaire (SRS-22) results of patients who self-selected either conservative or surgical treatment.

METHODS

Single institution review of prospectively collected data for patients presenting with SK from 2006 to 2014. Forty-five of 55 patients returned for 2-year follow-up. Patients were divided into operative (n=27) or nonoperative (n=18) groups based upon their self-selected method of treatment. Radiographic data and SRS-22 scores were collected at initial presentation and 2-year follow-up.

RESULTS

Operatively treated patients had larger initial sagittal Cobb angles and lower SRS-22 scores in the pain and appearance domains. Two years postoperatively, surgically treated patients had smaller Cobb angles and improved scores in these SRS-22 domains. Nonoperatively treated patients did not deteriorate over time.

CONCLUSIONS

Patients who elect to receive operative treatment for SK have improved radiographic and SRS-22 parameters at 2-year follow-up compared with patients who elect nonoperative treatment. Not surprisingly, patients selecting surgical treatment had greater sagittal Cobb angles and greater levels of pain and dissatisfaction with their appearance. However, at 2-year follow-up, surgical patients experience greater (and significant) change on all parameters; exhibiting smaller Cobb angles, less pain, and greater satisfaction with their outcomes. Nonoperatively treated patients do not deteriorate over 2 years.

LEVEL OF EVIDENCE: Level II-prognostic study.
