A pilot study to explore if the age that women undergo hallux valgus surgery influences the post-operative range of motion and level of satisfaction

Background Scarf and Akin osteotomies are commonly used to treat hallux valgus. One post-operative complication is a reduction in the range of motion at the first metatarsophalangeal joint. This can cause pain and restrict the heel height of footwear. This pilot study aims to examine if women's age has an effect on the post-operative outcome following Scarf and Akin osteotomies. Methods A pilot study using a convenience sample compared the outcomes of two groups of female patients, those aged under 50 and those aged over 50. The range of motion at the first metatarsophalangeal joint was measured using a goniometer, the American Orthopaedic Foot and Ankle Society (AOFAS) scale and satisfaction levels were collected 2 years post-operatively. Results There were no significant statistical differences between the two age groups for the outcomes measured. Similar AOFAS scores and ranges of motion were found for both age groups. Satisfaction levels were high but the under 50-year group were slightly less satisfied. Conclusions The outcome of this pilot study suggests that age does not have an effect on the range of motion of the first metatarsophalangeal joint, the AOFAS score or the level of patient satisfaction 2 years following Scarf and Akin osteotomies.sch_pod20inpress1856inpress
