Surgical Exposure Trends and Controversies in Extremity Fracture Care

Surgical exposures for the management of extremity fractures continue to evolve. Strategies to achieve satisfactory articular reconstitution require surgeons to have an appreciation and understanding of various conventional and contemporary surgical approaches. The recent literature has witnessed a surge in studies on surgical approaches for the fixation of extremity fractures. This increased interest in surgical exposures resulted from not only a desire to enhance outcomes and minimize complications but also a recognition of the inadequacies of traditionally accepted surgical exposures. Contemporary exposures may be modifications or combinations of existing exposures. All surgical exposures require proper surgical execution and familiarity with regional anatomic structures. Exposures, whether conventional or contemporary, must provide sufficient access for reduction and implant insertion. Proper exposure selection can greatly enhance a surgeon's ability to achieve acceptable reduction and adequate fixation. Unique characteristics of both the patient and his or her fracture pathoanatomy may dictate the surgical approach. Patient positioning, imaging access, and concomitant comorbidities (medical, systemic trauma, and regional extremity related) also must be considered. Minimally invasive methods of reduction and fixation are attractive and have merit; however, adherence to them while failing to achieve satisfactory reduction and fixation will not generate a desirable outcome. Surgeons should be aware of several site-specific anatomic regions in which evolving surgical exposures and strategies for extremity fracture management have had favorable outcomes.
