Introduction:
Hallux valgus deformity severity is one determent for the surgical procedure for hallux valgus (HV) correction. HV deformities are usually classified into mild/moderate/severe. The aim was to investigate the cut-off criteria used to classify HV deformity.
Materials And Methods:
The study was based on a previous living systematic review. Four common databases were searched for the last decade. All review-steps were conducted by two reviewers. Data assessed were the individual cut-off values used to classify HV deformity into mild/moderate/severe, and the referenced classification systems.
Results:
46 studies were included. 21/18 studies grade deformity based on the intermetatarsal angle (IMA)/ hallux valgus angle (HVA) with great heterogeneity throughout the different cut-off values. The most referenced classification systems were the Coughlin and Mann's and the Robinson classification.
Conclusions:
The currently used classification systems are heterogenic, and no standard could be defined. The community should define a uniform classification system.
Level Of Evidence:
Level I, systematic review of randomized controlled trials and prospective comparative studies.
