Most fractures heal with restoration of bone and joint function. Disability is generally temporary in these instances, and there is no permanent impairment to be rated in the majority of cases. However, multiple complications can occur that can lead to loss of skeletal function, restricted range of motion, and associated soft tissue injuries, and neurovascular damage can dramatically and severely compromise function and performance. Clearly, not all fractures heal within the timeframes as outlined in Table 2, and determination of the point of maximum medical improvement, which must be achieved in order to declare an impairment as permanent, can be challenging in these cases. Some individuals with fractures that demonstrate bone union radiologically may develop long-term disability; nearly 30% of individuals with a unilateral lower extremity fracture will not return to work within 12 months of injury. In the absence of a complicating soft tissue injury, the explanation for this discrepancy between impairment and disability can be elusive. During the past 10 years, improved systems of trauma care have reduced mortality rates in the United States. As greater numbers of persons survive motor vehicle accidents and other major trauma, the possibility exists that increasing numbers of fractures leading to impairment or disability may be seen. Recognition of how and when fractures heal, possible complications that may arise, risk factors for long-term disability, and the correlation of vocational and avocational physical demands with the resultant outcome will enable the clinician to appropriately and accurately assess disability status, design a rehabilitation program, and assign an impairment rating.
