The correct answer is 3. Type 3 fractures involve the lateral third of the clavicle, which are proximal to the shoulder joint.

Type 1 fractures involve the middle third of the clavicle and are minimally displaced.

Type 2 fractures also involve the middle third of the clavicle but are more displaced.

Type 4 fractures occur closer to the sternum in the medial third of the clavicle.

 It is important to be aware of and review the various classification systems. For example, the Allman Classification divides clavicle fractures into three groups:

  •  Group I (Middle Third Fractures): The most common group includes fractures in the middle third of the clavicle. These fractures are often caused by a direct blow to the clavicle or falling onto an outstretched hand. They are further classified into three types:

Type I A: Non-displaced fractures.

Type I B: Fractures with minimal displacement.

Type I C: Fractures with significant displacement.

  • Group II (Lateral Third Fractures): These fractures occur proximal to the lateral (outer) third of the clavicle, closer to the glenohumeral joint. They are less common and are usually caused by a fall directly onto the shoulder. This group is divided into two types:

Type II A: Non-displaced fractures.

Type II B: Fractures with displacement.

  •  Group III (Medial Third Fractures): These include fractures in the medial (inner) third of the clavicle, proximal to the sternum. They are less common and are often caused by a direct blow to the clavicle. Group III fractures can also be further classified based on displacement.

 Thus, it is important to note that classification systems can vary in terminology and specifics, and the treatment approach differs based on the specific fracture characteristics. Treatment options range from conservative management with immobilization and physical therapy to surgical intervention in cases of severe displacement or complex fractures.
