Background:
Hallux valgus (HV) has been reported to impair postural stability. However, whether comorbid hammer toe affects postural stability in patients with HV remains unclear.
Methods:
This study assessed static and dynamic postural stability in 45 patients with HV, divided into two groups: those with (H(+)) and without (H(-)) comorbid hammer toe. Static stability was evaluated using stabilometer, whereas dynamic stability was assessed with the Berg Balance Scale (BBS), Timed Up and Go (TUG) test, and Falls Efficacy Scale-International (FES-I).
Results:
Static stability parameters showed no significant differences between groups H(-) and H(+). The BBS score was lower in group H(+) than in group H(-) (P = .002), whereas the TUG and FES-I scores were higher in group H(+) than in group H(-) (P = .033 and.017, respectively).
Conclusions:
Comorbid hammer toe affects dynamic postural stability and increases the risk of falls in patients with moderate-to-severe bilateral HV.
Level Of Evidence:
Level 3.
