  • Title: Is generalized ligamentous laxity a prognostic factor for recurred hallux valgus deformity?
    Author: Cho BK, Park JK, Choi SM, SooHoo NF.
    Journal: Foot Ankle Surg; 2019 Apr; 25(2):127-131. PubMed ID: 29409294.
    Abstract:
    BACKGROUND: This study was performed to evaluate the intermediate-term clinical outcomes after proximal chevron osteotomy for hallux valgus in patients with generalized ligamentous laxity, and to determine the effect on postoperative recurrence of deformity. METHODS: There were 23 cases in laxity group (Beighton score ≥5 points) and 175 in non-laxity group with a mean followup of 46.3 months. Clinical evaluation consisted of the AOFAS score, Foot and Ankle Ability Measure (FAAM), and radiographic measurement of hallux alignment. Risk factors associated with postoperative recurrence were evaluated using univariate analysis. RESULTS: Recurrence rates were 21.7% in the laxity group and 17.1% in non-laxity group (P=.218). There were no significant differences in clinical and radiographic measurements at final followup between the 2 groups. Preoperative HVA and IMA were found to be predictive factors of recurrence (OR=6.3, 4.2; P=.001, .018, respectively). CONCLUSION: There were no statistical differences in the clinical and radiographic outcomes between hallux valgus with and without generalized ligamentous laxity. Generalized ligamentous laxity demonstrated no definitive effects on postoperative recurrence of hallux valgus deformity.
