Purpose: Plate-screw fixation and sprains are commonly used methods in the surgical treatment of midshaft
clavicle fractures. Generally, rotational deformities are neglected during surgery. Main goal is; investigated
the effect of malrotational midshaft clavicle deformity on acromioclavicular and coracoclavicular joint with
finite element analysis method.
Material methods: The anatomical shoulder joint was modeled using computed tomography images. The
midshaft fracture was formed on the clavicle. The fractures were rotated at 5 °, 10 °, 15 ° and 20 ° in the
anterior and posterior axial rotation, respectively; malunion models were created. The resulting models
were made non-linear using the finite element program ANSYS (version 18) and the same boundary
conditions were applied in all models.
Results: At different rotational degrees of the fracture line, tensions were calculated in acromioclavicular
and coracoclavicular joints. Anterior and posterior axial rotation in midshaft clavicle fracture increases the
tension on acromioclavicular and coracoclavicular joints. Especially lodings in posterior axial rotation of
midshaft clavicle fracture is more than the anterior.
Conclusions: Rotational deformities in the surgery of the midshaft clavicle fractures affect the shoulder
joint biomechanics, resulting in an increase in the loading on AK and CC joints. This may cause pain in the
shoulder joint, which may lead to joint degeneration later on.
