Hallux valgus is a disease
affecting the joint between the toe and the metacarpus to which the finger is
attached. As a result of the angulation of the big toe, the joint with the
metacarpus is pushed and a fluid retention occurs. This disease is rarely seen
in societies without a shoe wearing habit, but it is likely to be seen in women
wearing heels and narrow-nosed shoes. Splint, exercise and joint mobilization
are applied in patients with hallux valgus that have not reached the surgical
level. While it is sufficient for the patient to perform 2-3 sessions a day for
exercise and joint mobilization, the patient has to use the splint during out
of the period that covers his / her personal care needs. Splits in the market
are produced in standard sizes. In the production of standard splints,
parameters such as patient's foot size, hallux valgus grade, finger thickness
and length, gender and age are not considered. Therefore, since the splints
produced are not specific to the person, a desire to use them permanently does
not come out for the users. This has an adverse effect on the healing process
of the disease.

 In
this study, a software was developed to create a splint model based on patient
parameters in WPF (Windows Presentation Foundation) platform. By entering
parameters to the software such as patient's foot size, hallux valgus grade,
finger thickness and length, creation of a personally customized splint design
is provided. A standard splint model, which was previously designed in the 3D
MAX program, is installed in the software. Later, according to the entered parameters
of the patient, the splint is formed as customized for the individual. Thus,
the patient's discomfort arising from the use of the splint disappears. Along
with the continuous and regular use of splints, however, it appears that the
healing process runs faster.

 A
custom-designed splint and a splint produced by different techniques were
compared in terms of production technique, material, cost and duration.
According to this comparison, a custom splint produced by 3D printer provides
advantages in terms of cost and production time. However, it seems that it does
not have any advantage in terms of material and production techniques used.
