Abstract:
The intramedullary nailing for humeral shaft fractures has become popular fixation method. It affords less invasive procedure, good stability and early rehabilitation. However many complications were reported such as nonunion, pain and motion limitation of shoulder. We managed 33 patients using interlocking intramedullary nail for the humeral shaft fractures, and nonunion occurred in 9 patients. We reviewed these 9 cases and analyzed the relationship between the nonunions and the fracture sites as well as fracture types. The results were as follows; 1. Nonunion occurred in 9 patients of 25 patients treated closed reduction, but did not occur in 8 patients treated open reduction. 2. The union was obtained in all 6 patients with proximal one third fracture. But nonunion occurred in 6 patients of 19 patients with middle one third fracture and in 3 patients of 8 patients with distal one third fracture. 3. Nonunion after interlocking nails for humeral shaft fractures did not occur in all 6 spiral fracture patients. Nonunion occurred in 5 patients of 8 comminuted fracture patients, in 3 patients of 6 transverse fracture patients and in 1 patient of 3 oblique fracture patients with below the middle one third of humerus. Our study showed that the high rate of nonunion occurred in the comminuted, transverse and oblique fracture below the middle one third of humerus. On the basis of these findings, we recommend that closer attention should be paid when choose the fixation method in these types of the humeral shaft fractures.
