Radiographic evaluation of reconstructive surgery for segmental bone defects: What the radiologist should know about distraction osteogenesis and bone grafting.

Radiologists work in conjunction with orthopedic surgeons to evaluate the progression of bone healing and identify potential problems during bone reconstruction. Accurate evaluation and identification of healing progression or complications are critical to optimizing successful patient outcomes with either distraction osteogenesis or bone grafting. Therefore, radiologists must understand the fundamental concepts behind these surgical reconstructive techniques in order to provide accurate postoperative radiographic assessments. The cases and discussion within this review aim to provide this foundational knowledge.
