Effect of Age on Clinical and Radiological Outcomes of Hallux Valgus Surgery.

BACKGROUND

The prevalence of hallux valgus increases with age. However, no studies have compared the effectiveness of surgical correction among different age groups. This study investigated the influence of age on clinical and radiological outcomes following hallux valgus surgery.

METHODS

Patients who underwent correction for hallux valgus at an academic hospital were stratified into 3 age groups: younger (<50 years), middle-aged (50-59 years), and older (≥60 years). Functional outcomes and satisfaction questionnaires were collected preoperatively and at 6 months and 2 years postoperatively. Radiological recurrence and reoperations were recorded at follow-up. There were 193 patients (93% female): 34 younger, 74 middle-aged, and 85 older.

RESULTS

The preoperative hallux valgus angle was significantly greater in older patients ( < .001). The older group had 3 perioperative complications ( = .144) and showed a trend toward a longer hospital stay ( = .083). There was no difference in visual analog scale, American Orthopaedic Foot & Ankle Society score, or SF-36 among the groups at 6 months or 2 years. Using multiple regression, age was not associated with any outcome score. The satisfaction rates were 82%, 78%, and 83% in the young, middle-aged, and older groups, respectively ( = .698). There was no difference in the number of reoperations at a mean follow-up of 9.2 ± 2.2 years ( = .778), and no patients underwent reoperation for recurrent hallux valgus. The risk of recurrence was 5 times higher in older patients compared with younger patients (OR, 5.15; 95% CI, 1.10-24.03; = .037).

CONCLUSION

Age did not influence the perioperative, functional, or subjective outcomes following hallux valgus surgery. However, older patients should be counseled on the higher risk of recurrence following surgical correction.
