Soft Tissue Reconstruction

Soft tissue coverage of open fractures with wellvascularised tissues should be performed within 72 hours of injury or at the same time as internal fixation. It may be in the form of local or free flaps, and may comprise muscle, fasciocutaneous tissues, or both. Flap selection depends on multiple factors, including the size and location of the defect following wound excision, availability of flaps, and donor site morbidity. Local flaps are usually used to cover defects with a limited zone of injury. Anastomoses for free flaps should be performed outside the zone of injury. Experimental data suggest that coverage with muscle leads to improved healing of fractures. However, there is currently little clinical evidence to support the use of one form of soft tissue cover over another for open fractures of the lower limb. The plastic surgeon must always consider the donor site morbidity of the flap(s) chosen.
