Event Description
This report is being filed after the review of the following journal article: singh, s. Et al (2020), surgical management of bilateral hip fractures in a patient with fibro dysplasia ossificans progressive treated with the rar-g agonist palovarotene: a case report, bmc musculoskeletal disorders, vol. 21 (204), pages 1-8 (usa). This study presents a case report of a (b)(6) year-old male patient who sustained a left intertrochanteric fracture one year after starting palovarotene. Surgery was performed using a cephalomedullary nail (trochanteric fixation nail, depuy synthes, west chester, pennsylvania). After surgery, he received palovarotene at 20 mg/day for 4 weeks, then 10 mg/day for 8 weeks. Over the subsequent 2 months, the patient showed progressive clinical loss in the range of motion of the left hip and required the use of a cane for ambulation. A review of x-ray images at the time of the fracture showed no evidence of ho at the left hip (fig. 2a). Radiologically, ho and a callus were evident around the distal screw by the left knee after 4 months (fig. 2b). In addition, ho at the left hip was evident by 9 weeks and fully matured by 14 weeks (fig. 2c). Brooker class d ho was clearly present on imaging at 9 months after surgery and matured at 12 months after surgery (fig. 2d-e). Nine months after the left hip fracture, the patient had a second fall resulting in a subdural hematoma, left parietal bone fracture, and right intertrochanteric fracture. He underwent intramedullary nailing of the right hip using an identical long cephalomedullary nail, palovarotene 20 mg/day was started at fracture occurrence and continued for 4 weeks, then reduced to 10 mg/day for 8 weeks. Fracture healing was not delayed based on clinical imaging; however, the patient showed continued loss of mobility, requiring the use of a walker and wheelchair. Again, the patient showed multiple and prolonged fop flare-up activity, resulting in a significant increase in the number of flares/years. The right hip showed new development of brooker class b ho at the greater trochanter, near the insertion site of the intramedullary rod, by 3 months after surgery (fig. 3). This report is for an unknown synthes tfn constructs. This report is for (1) unk - constructs: tfn. This report is 1 of 1 for (b)(4).
