Abstract
The present study retrospectively analyzed 23 patients with ulnar fracture or bone nonunion who received treatment in the Department of Orthopedics, Second Affiliated Hospital of Soochow University between August 2001 and December 2008. These patients comprised 16 males, 7 females, and averaged 41.8 years old (range 20-72 years old). Of them, 14 had single ulnar fracture, 6 had monteggia fracture, 19 had fresh fracture, 1 had obsolete fracture, and 3 presented with bone nonunion and plate breakage following ulnar fracture. All patients received interlocking intramedullary nailing. Internal fixation time and the mean time to fracture healing were recorded. The function of nailed forearm was evaluated using Anderson criteria. All 23 patients were followed up in terms of intra- and post-operative complications for a period of 6 months -7.3 years. Following Hertel classification criteria, bone union occurring at a mean of 14.7 weeks was found in 23 patients. No intramedullary nail loosening, fragmentation, or incision infection was observed. Twenty patients had intramedullary nails removed but did not present recurred fracture. According to the Anderson evaluation criteria regarding forearm functions, the results were excellent in 22 patients and satisfactory in 1 patient. These findings indicated that interlocking intramedullary nailing for treatment of ulnar fracture provides less trauma, short recovery period, and low recurrence. For these advantages, it is suitable for treatment of ulnar shaft fracture, multi-segment ulnar fracture, bone defects, bone non-union, and the fractures failed after compression plating; in addition, it is a better choice in treating ulnar fracture in patients with severe soft tissue injury or osteoporosis.关键词
