A humeral fracture can be managed orthotically if it is in the __ of the humerus. The most important biomechanical principle when managing these fractures is __.

The management of humeral fractures orthotically is particularly effective when the fracture occurs in the distal two-thirds of the humerus. This location is significant because fractures in this area have a good potential for healing with appropriate support, allowing the use of an orthotic device rather than surgical intervention in many cases.

When addressing the biomechanical principles involved, soft tissue compression is critical. This principle ensures that the orthotic device applies adequate pressure to the surrounding soft tissues. By compressing the soft tissues, the orthosis can stabilize the fracture, reduce pain, and facilitate proper alignment during the healing process. This approach not only aids in fracture stabilization but also helps mitigate the risk of displacement during the early stages of recovery.

In contrast, options that refer to different segments of the humerus or biomechanical principles may not align as effectively with established clinical practices for managing humeral fractures. For instance, a focus on areas like the proximal one-third might require different considerations due to the proximity to the shoulder and associated soft tissue structures, while other principles like endpoint control or a three-point pressure system may serve different fracture types or locations inappropriately. Thus, soft tissue compression in the context of distal two-thirds humeral fractures represents the most applicable and effective strategy in
