				        	 Objective:To establish an efficient classification and treatment system for limb long bone defects.
				        	
				        
				        	Methods:Based on the length of bone defect, soft tissue injury and wound infection, a new classification and treatment system was proposed with reference to Gustilo-Anderson classification for open fractures and Orthopedic Trauma Association (OTA) classification.
				        	
				        
				        	Results:We divided the limb long bone defects into 3 types, each of which was subdivided into 4 subtypes depending on concomitant soft tissue defect and/or infection. Type Ⅰ are bone defects less than 4 cm in length, including type Ⅰa (simple bone defects with a limited extent), type Ⅰb (bone and soft tissue defects), type Ⅰc (bone defects with infection) and type Ⅰd (bone defects with infection and soft tissue defects). Type Ⅱ are bone defects ranging from 4 to 10 cm in length, including type Ⅱa (simple bone defects with a large extent), type Ⅱb (bone and soft tissue defects), type Ⅱc (bone defects with infection) and type Ⅱd (bone defects with infection and soft tissue defects). Type Ⅲ are bone defects larger than 10 cm in length, including type Ⅲa (simple bone defects with a very large extent), type Ⅲb (bone and soft tissue defects), type Ⅲc (bone defects with infection) and type Ⅲd (bone defects with infection and soft tissue defects).
				        	
				        
				        	Conclusion:Our new classification and treatment system for long limb bone defects is more efficient and intuitive, facilitating clinical diagnosis and treatment of limb long bone defects.
