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