Event Description
Device report from synthes reports an event in (b)(6) as follows: this report is being filed after the review of the following journal article: choi, j. -y. , sung, y. -b. , yoo, j. -h. , and chung, s. -j. (2014), factors affecting time to bony union of femoral subtrochanteric fractures treated with intramedullary devices, hip pelvis, vol. 26 (2), pages 107-114 (korea, south). The aim of this retrospective study is to evaluate the factors affecting the bone union time and the occurrence of nonunion after intramedullary nailing of subtrochanteric femoral fractures in adults. Between february 2004 to march 2013, a total of 31 patients (22 male and 9 female) with an average age of 53. 7 years (range, 18-78 years) underwent femoral intramedullary treatment. Proximal femoral nail (pfn), pfn antirotation (pfna), and a2fn (synthes, paoli, switzerland) were utilized for the surgery. Pfn, pfna, and a2fn were used for 13, 12, and 6 cases, respectively. The average follow-up period was 17. 5 months (range, 13-50 months). The following complications were reported: 3 patients displayed nonunion. To treat the ununited fractures, autogenous bone grafts (2 cases) and intramedullary nailing exchange to plating and bone graft (1 case) were performed and achieved the bony union without additional complications. An unknown number of patients had an average degree of varus/valgus deformity was varus 0. 45° (varus 6° -valgus 8°). An unknown number of patients had a postoperative displacement of fracture. A (b)(6) year-old female patient had nonunion seen on a radiograph at 9 months. A follow-up radiograph at 2 years shows bone union after revision surgery with locking compression plate fixation and autogenous iliac bone graft. This report is for an unknown synthes pfn constructs, unknown synthes pfna constructs, and unknown synthes a2fn constructs. A copy of the literature article is being submitted with this medwatch. This report is for (1) unk - constructs: a2fn. This report is 2 of 4 for (b)(4).
