Relationship Between Lower Extremity Alignment and Hallux Valgus in Women.

BACKGROUND:
Most previous studies on hallux valgus focused on the possible relationship between this deformity and muscles and/or ligaments in the foot and lower leg. Very little is known about the relationship between hallux valgus and alignment of the proximal joints. The aims of the present study were to determine the extent to which lower extremity alignment characteristics of the hip, knee, ankle, and foot were related to the manifestation of hallux valgus and to identify variables predicting its development in women.

METHODS:
A group of 25 women with hallux valgus and 24 control women, age 51 to 80 years, were interviewed and screened for the current study. Measurements recorded were hallux valgus angle; intermetatarsal angle; a set of body physique measures (eg, height); range of motion at the hip, knee, ankle, and foot joints; general hypermobility; lower extremity alignment (eg, tibiofemoral angle); and 9 anatomical anomalies (eg, knee valgus/varum).

RESULTS:
Women with hallux valgus manifested notably higher range of motion at their joints, different lower extremity alignment, higher prevalence of general joint hypermobility, and higher prevalence of anatomical anomalies compared with controls. Estimated marginal means for most joint range of motion and lower extremity alignment measurements were notably higher for the hallux valgus group.

CONCLUSION:
Lower extremity alignment and joint range of motion were correlated with hallux valgus. Future studies could possibly identify anatomic risk factors for the development of hallux valgus, nonsurgical methods of prevention and adjunctive surgical methods of treatment.

Gait parameters associated with hallux valgus: a systematic review
Sheree E Nix, Bill T Vicenzino, Natalie J Collins and Michelle D Smith
Journal of Foot and Ankle Research 2013, 6:9

Background
Hallux valgus (HV) has been linked to functional disability and increased falls risk in older adults. However, specific gait alterations in individuals with HV are unclear. This systematic review investigated gait parameters associated with HV in otherwise healthy adults.

Methods
Electronic databases (Medline, Embase, CINAHL) were searched to October 2011, including cross-sectional studies with clearly defined HV and non-HV comparison groups. Two investigators independently rated studies for methodological quality. Effect sizes (95% confidence intervals (CI)) were calculated as standardized mean differences (SMD) for continuous data and risk ratios (RR) for dichotomous data.

Results
Nine studies included a total of 589 participants. Three plantar pressure studies reported increased hallux loading (SMD 0.56 to 1.78) and medial forefoot loading (SMD 0.62 to 1.21), while one study found reduced first metatarsal loading (SMD -0.61, CI -1.19 to -0.03) in HV participants. HV participants demonstrated less ankle and rearfoot motion during terminal stance (SMD -0.81 to -0.63) and increased intrinsic muscle activity (RR 1.6, 1.1 to 2.2). Most studies reported no differences in spatio-temporal parameters; however, one study found reduced speed (SMD -0.73, -1.25 to -0.20), step length (SMD -0.66 to -0.59) and less stable gait patterns (SMD -0.86 to -0.78) in older adults with HV.

Conclusions
HV impacts on particular gait parameters, and further understanding of potentially modifiable factors is important for prevention and management of HV. Cause and effect relationships cannot be inferred from cross-sectional studies, thus prospective studies are warranted to elucidate the relationship between HV and functional disability.
