Abstract
Objective To retrospectively analyze the factors associated with noninfectious bone nonunion. Methods From January 2005 to December 2007, 75 cases of bone nonunion were admitted, including 59 cases of noninfectious bone nonunion. 59 cases of noninfectious bone nonunion were located at the following sites: clavicle in 1 case, humerus in 8 cases, ulnar radius in 7 cases, femur in 23 cases, and tibiofibula in 20 cases. The main causes of nonunion were unreliable fixation and stress interference at the bone ends, and other causes were poor fracture repositioning, large fracture gaps, and poor blood supply to the bone ends. Conclusion Medical factors are still an important cause of bone discontinuity. Most bone nonunion can be avoided if attention is paid to it early in treatment.
Bone nonunion is a manifestation of the cessation of new bone regeneration at the fracture end and is one of the common problems after fracture. With the improvement and development of treatment, although more than 90% of fractures can be healed, bone nonunion still occurs in nearly 10% of cases. The author is a Chinese medical team member in Guinea, working at the Asteen Hospital in the capital city of Guinea. Although the local medical level is not as good as that in China, the causes of bone nonunion are the same. From January 2005 to December 2007, the author treated 498 trauma patients in the hospital in Asteen, and there were 75 cases of bone nonunion, including 59 cases of infected bone nonunion, and the reasons for their occurrence are analyzed.
