Event Description
This report is being filed after the review of the following journal article: kim, y. V. Et al (2022), impact of coronal plane fragments and anterior big neck fragments on the occurrence of perioperative lateral wall fractures in ao/ota 31-a1,2 intertrochanteric fractures treated with cephalomedullary nailing, european journal of trauma and emergency surgery, vol xx (xx), pages 1-7 (korea, south). The aim of this retrospective study was to find the association between the type of coronal fragments and perioperative lateral wall fractures during treatment of pertrochanteric fractures with cmns. Between september 2016 to december 2020, a total of 463 patients (136 male and 326 female) with a mean age of 80. 1 years (31¿100) were included. The cephalomedullary nails used were pfna (pfnaii, synthes, paoli, pa, usa) or gamma nails (stryker, mahwah, nj, usa). Provisional pins, which keep the fracture reduction intact during proximal reaming and nail insertion, were used by the surgeon's discretion. Postoperative radiographs were obtained the day after surgery. Follow up radiographs were taken one week later, two weeks later, one month later, three months later, and so on. Perioperative fracture of the lateral wall was confirmed by the presence of fracture line at the blade entry site on both anteroposterior and lateral radiographs (fig. 3). The following complications were reported as follows: 22 patients had perioperative lateral wall fractures (implant used in 21 were pfna and 1 with a competitor). Patients treated with pfna were as follows: a 90-year-old female patient, an 82-year-old female patient, an 82-year-old male patient, an 83-year-old female patient, a 90-year-old female patient, an 83-year-old male patient, an 89-year-old male patient, a 91-year-old female patient, a 75-year-old female patient, a 77-year-old male patient, a 73-year-old male patient, an 88-year-old female patient, an 87-year-old female patient, an 81-year-old female patient, an 89-year-old female patient, a 100-year-old female patient, an 82-year-old female patient, a 92-year-old male patient, a 79-year-old female patient, a 68-year-old male patient, an 88-year-old female patient. This is report 11 of 20 for (b)(4). This report is for an unknown synthes pfna ii. (75 year old female patient) this complaint is linked to (b)(4).
