Intramedullary nailing of humeral shaft fractures. A retrospective study of 126 cases.
Antegrade intramedullary nailing with four different implants was used in 126 humeral shaft fractures. There were 74 acute fractures, 17 pathologic fractures, 16 fractures malaligned in a hanging cast or brace, 15 fractures with delayed union and 4 fractures that were nailed after failed open reduction and internal fixation. The nonunion rate was 21/95 after primary operation, and after reoperations 14/95. Distraction of the fracture was a significant cause of nonunion, but not type of fracture, localization, implant, and delay between injury and surgery. Shoulder joint function was significantly impaired in 25/67 patients. The patients regarded the result as good or satisfactory in 41/67 of the cases who were followed mean 3 (0.5-10) years. We conclude that antegrade intramedullary nailing of humeral shaft fractures leads to a substantial risk of non-union and impairment of shoulder function. It can be recommended as primary treatment only when nonoperative treatment is likely to fail.
