Comminuted Fracture Case Study

Decent Essays

The fracture seen in the images is called a comminuted fracture and is seen on the proximal end of the humerus. A comminuted fracture Is identified by the bone being spit into multiple fragments. As seen in the images provided the humeral head is seen with 2 fragments coming off of the medial and lateral aspects. Due to the multiple fragments as well as the patients MOI I deemed this fracture comminuted. The etiology for a comminuted fracture is described as an extreme pressure being exerted on a bone1. This matches the MOI of the patient who claimed that she fell onto her shoulder after slipping on the ice. The extreme pressure would be her entire body weight being exerted onto her humeral head during the fall and with her decreased bone density …show more content…

This means that because of her fragile bones her body weight is enough to break her humeral head in to fragments. Treatment for this fracture is surgical fixation of the fragments using plates and screws which also matches the treatment this patient received. It was noted that this patient underwent surgery to help the different fragments fuse back together. The MOI, symptoms and treatment for this patient matches with that of a comminuted fracture.
Fracture Description:
Patient came into the hospital as an outpatient claiming that they were experiencing tenderness and stiffness in their left shoulder. Upon reading the requisition as well as asking the patient more questions I discovered that the patient had slipped and fell onto the ice 3 days previous. This patient explained that they were reluctant to go to the doctors as they already had stiffness in the left shoulder and they were convinced it was nothing serious. After taking the first image (the AP) it became clear that there was a comminuted fracture of the proximal humerus. A …show more content…

Other complications can be infection caused by the surgery2. Even before treatment some complications of this fracture can be ripping of the skin, muscles and blood vessels causing it to become an open fracture. Substantial nerve damage can also be a risk if the fractured fragments are moved to much. Open fractures have a high risk of infection from the outer environment2. The fracture in the included images is a closed fracture. With closed fractures there is less chance of initial infection, it is very important that the patient follows the post operative instructions. By changing the dressings on the wound with clean ones regularly will help avoid infections, and by resting the part (e.g. keeping it still, avoid lifting with that arm, etc.) there is less chance of the hardware failing or malunion of the individual fragments3. If in this case the patient were still experiencing pain follow up x-rays would then be ordered to check how the fracture looks and to check for complications. With malunion you would be able to see if the humerus had bony deformities associated with malunion where the different fracture fragments have not properly fused back with the humerus. If the follow up x-rays show that the fracture it not healing after 6-8 weeks (the average healing time for a humerus) then more follow up x-rays may also be ordered every month as this an indication of either delayed or non-union of the
