Abstract
Background
Hallux valgus is a complex deformity of the first ray and forefoot, which can be surgically treated by different procedures and osteotomies. Preoperative planning includes antero-posterior and lateral plain films. The effect of weightbearing on the results of the standardized measurements is still the subject of debate.
Materials and Methods
We evaluated the effect of weightbearing on the results of measurements and decision making by expert evaluators. Twenty one expert foot & ankle surgeons were given weightbearing and nonweightbearing anteroposterior plain foot films of patients with hallux valgus. They were asked to measure three standard angles and then to select the most appropriate procedure out of a short list.
Results
Using paired Student T-test, no difference in the angles measured or the procedures chosen was detected between weightbearing and nonweightbearing films.
Conclusion
Although it is generally accepted that decisions regarding the treatment of hallux valgus should be based on plain weightbearing films, in this study we established the nonweightbearing films can be reliably used to choose the surgical procedure.
