Diagnosis of Clavicular Fractures: Clinical Evaluation, Physical Examination, and Imaging Studies Explained

Dx of clavicular fractures?

The diagnosis of clavicular fractures involves a combination of clinical evaluation, physical examination, and imaging studies

The diagnosis of clavicular fractures involves a combination of clinical evaluation, physical examination, and imaging studies. Here is a detailed explanation of the diagnostic process for clavicular fractures:

1. Clinical history: The first step in diagnosis is obtaining a thorough clinical history, including details about the mechanism of injury, any associated symptoms, and any pre-existing conditions that may affect bone health (e.g., osteoporosis).

2. Physical examination: A physical examination is crucial to assess the clavicle for any signs of fracture. The following findings may suggest a clavicular fracture:

a. Pain: Patients often experience localized pain over the fracture site, worsened by movement or palpation.

b. Swelling and bruising: Swelling and bruising may be present around the fracture site due to soft tissue injury or bleeding.

c. Deformity: An obvious deformity, such as a bulge or a tenting of the skin, may be visible at the site of the fracture.

d. Difficulty moving the arm: Patients may have difficulty lifting or moving the affected arm due to pain and instability caused by the fracture.

3. Imaging studies: X-rays are generally the primary imaging modality used for diagnosing clavicular fractures. They offer excellent visualization of clavicle fractures and help determine the fracture type and displacement. The following views are typically obtained:

a. Anteroposterior (AP) view: This view is taken with the patient standing, with the affected shoulder against the X-ray plate. The X-ray beam is directed perpendicular to the clavicle, and it provides a comprehensive image of the clavicle.

b. Axillary view: This view is taken with the patient seated and their affected arm abducted at a 90-degree angle. It provides a clear image of the acromioclavicular joint, which can help assess for associated injuries.

c. Occasionally, additional imaging may be required, such as a CT scan or MRI, if there is suspicion of more complex fractures, involvement of nearby structures, or to assess for associated injuries.

4. Fracture classification: Clavicular fractures can be classified based on their location. The most common classification system is the Allman classification, which divides clavicle fractures into three groups:

a. Group I: Fractures that occur in the middle third of the clavicle (~80% of all clavicle fractures).

b. Group II: Fractures that occur in the lateral third (distal) portion of the clavicle (~15%).

c. Group III: Fractures that occur in the medial third (proximal) portion of the clavicle (~5%).

Based on the above diagnostic steps, a healthcare professional, such as a physician or orthopedic specialist, can accurately diagnose a clavicular fracture and determine the appropriate course of treatment, which may include conservative management with a sling or more invasive interventions, such as surgery, depending on the severity and displacement of the fracture.
