Which statement about hip dislocation in the field is true?

The statement regarding posterior hip dislocation being the most common is accurate. In traumatic hip injuries, especially those resulting from significant force such as motor vehicle collisions or falls from a height, the posterior dislocation occurs more frequently than anterior dislocation. This is primarily because of the anatomy of the hip joint, where a force applied from the front can easily push the femoral head backward out of its socket.

Understanding the prevalence of posterior dislocations is crucial for wilderness medicine practitioners, as it informs initial assessment and management strategies in the field. Correctly identifying the most common type of dislocation allows for appropriate care decisions, such as the need for urgent transport and stabilization techniques. The other statements may not hold true in this context, as not all dislocations are visible on X-rays, the severity of each type of dislocation can vary based on several factors, and splinting techniques can, in fact, be applied to dislocated hips under certain circumstances. This knowledge is essential in wilderness emergency settings where resources and facilities are limited.
