This report is being filed after the review of the following journal article: vande voorde k, dauwe j, van oost j (2018), late presentation of an iatrogenic pseudoaneurysm of the profunda femoris artery following intramedullary nailing, hindawi case reports in orthopedics, volume 2018, article id 8270256, pages 1-5, (belgium).This is a report of a well-documented case of an uncommon complication resulting in pseudoanurysm after intramedullary nailing of an intertrochanteric femoral fracture.This is a case report of a (b)(6) year old caucasian male patient presented with severe pain in the right hip after a high energy trauma due to a fall.Intertrochanteric hip fracture was diagnosed on a plain x-ray of the painful hip and pelvis.Closed reduction and internal fixation were performed using an unknown synthes 170 mm 125 degrees proximal femoral nail antirotation intramedullary nail, 11mm diameter.An unknown synthes 115mm blade and an unknown synthes 38mm distal locking screw were inserted with the use of the aiming arm.For distal locking, a drill sleeve, a protection sleeve, and a 4.2mm calibrated drill bit (340mm) were used.Drilling was guided, however not guarded.There were no intraoperative or immediate postoperative complications.Postoperative radiographs were satisfactory.8 months postoperatively, the patient had progressive swelling of the right thigh.Clinical examination revealed a nontender diffuse swelling over the proximal part of the right thigh without well-defined borders, redness, or fluctuation.Ultrasound revealed a calcified old muscular hematoma localised medial to the femoral diaphysis.X-rays confirmed the presence of a medial mass centred over the distal locking screw with calcification of the peripheral borders, suggestive for an (infected) hematoma.Compression and severe osteolysis of the medial border of the femur were seen (figure 3).Contrast-enhanced computed tomography (ct) was performed, showing an active extravasation in the hematoma which led to the diagnosis of pseudoaneurysm.Severe scalloping of the medial femoral cortex was confirmed (figure 4).The patient was referred to the department of vascular surgery for open drainage.Preoperative findings showed a profunda femoris artery (pfa) lesion facing the distal locking screw which was managed by direct arterial suture.The screw was not visible and therefore left in place.The patient was followed up regularly, and further evolution was uneventful.This report is for an unknown pfna blade.This is report 2 of 3 for (b)(4).
