Which therapeutic approach uses allografts to aid in the management of nonunion fractures?

The use of allografts in the management of nonunion fractures is effectively associated with low-intensity pulsed ultrasound. This therapeutic approach involves applying ultrasonic waves to promote healing in fractured bones, which can help facilitate the incorporation of allografts. Allografts are particularly useful as they provide a biological scaffold and deliver growth factors, enhancing the healing process.

Low-intensity pulsed ultrasound has shown effectiveness in stimulating osteogenesis and improving bone healing rates, making it a suitable choice in cases where traditional mechanical methods of stabilization have failed, such as in nonunion fractures. By enhancing the biological environment for healing with this method, clinicians can support the integration of the allograft, addressing the underlying issues that lead to nonunion.

In contrast, the other options involve different therapeutic modalities that do not utilize allografts as part of their approach. For instance, electrical bone stimulation as a method can help promote healing but does not directly involve grafting techniques. Bone grafting with autografts involves using the patient’s own tissue, which is different from using allograft materials from a donor. High-intensity focused ultrasound represents a different therapeutic category primarily for tissue ablation and does not relate to the application of allografts in fracture management.
