Pelvic migration of the helical blade after treatment of transtrochanteric fracture using a proximal femoral nail☆
نویسندگان
چکیده
Proximal femoral nails with a helical blade are a new generation of implants used for treating transtrochanteric fractures. The blade design provides rotational and angular stability for the fracture. Despite greater biomechanical resistance, they sometimes present complications. In the literature, there are some reports of cases of perforation of the femoral head caused by helical blades. Here, a clinical case of medial migration of the helical blade through the femoral head and acetabulum into the pelvic cavity is presented.

Backout of the helical blade of proximal femoral nail antirotation and accompanying fracture nonunion.
This article describes a case of backout of the helical blade, a rare complication of proximal femoral nail antirotation. A 31-year-old man had sustained a trochanteric fracture of his right femur. Fracture fixation using proximal femoral nail antirotation and autologous bone grafting 7 months later were performed at another hospital. However, bony union was not obtained, and the patient's pain...
متن کاملReason and treatment of failure of proximal femoral nail antirotation internal fixation for femoral intertrochanteric fractures of senile patients.
The cause of postoperative failure after the treatment of femoral intertrochanteric fracture with proximal femoral nail antirotation (PFNA) was analyzed, and the reoperative methods were examined. Nine failures of 308 femoral intertrochanteric fracture patients with PFNA were treated with femoral prosthesis total hip replacement (THR) and reoperative internal fixation. All nine patients were an...
متن کاملNew Proximal Femoral Compaction Blade Provides Strong Antirotation Stability of the Femoral Head.
This study investigated the mechanical properties of a new rectangular compaction blade and compared this blade with other types of nail. Three types of nail were tested: the Magnum lag screw (Robert Reid Inc, Tokyo, Japan), proximal femoral nail, and Magnum Fid blade (Robert Reid Inc). The nails were inserted into solid rigid polyurethane foam, and the torsional moments were loaded with an Ins...
متن کاملDoes bone compaction around the helical blade of a proximal femoral nail anti-rotation (PFNA) decrease the risk of cut-out?
OBJECTIVES Because of the contradictory body of evidence related to the potential benefits of helical blades in trochanteric fracture fixation, we studied the effect of bone compaction resulting from the insertion of a proximal femoral nail anti-rotation (PFNA). METHODS We developed a subject-specific computational model of a trochanteric fracture (31-A2 in the AO classification) with lack of...

Background: Femoral shaft fractures are an incapacitating pediatric injury accounting for 1.6% of all pediatric bonyinjuries. Management of these fractures is largely directed by age, fracture pattern, associated injuries, built of the childand socioeconomic status of the family. We retrospectively evaluated the use of elastic stable intramedullary nail (ESIN)in surgical management of femoral s...
