An intramedullary nail for proximal femur fracture fixation comprises a femur nail (1a) which can be proximally inserted into the medullary canal of the femur, a femur neck screw (10a) that can be laterally inserted through a bore (7a) that extends obliquely to the longitudinal axis of the femur nail (1a) into the femur neck, and a locking element (16a) with at least one branch (18a) which … Confirm Guide Rod position in the window at the opposite end of the Ruler as shown in order to ensure accurate implant measurement. a socio unico. This should be filled and ready for use when you return home from the surgery center/hospital.

Push 1,2 A primary advantage is the ease of starting point entry. The intramedullary nail for femur and targeting device unit is inserted over the smooth guide wire ( ∅ 3.0mm) into the medullary canal by hand using light pressure with the targeting device oriented anteriorly. INTRAMEDULLARY NAILING AND THE FEMUR INTRAMEDULLARY NAILING AND THE FEMUR Mr. Amresh Singh ST3 Sunderland . The review concluded that reamed intramedullary nailing was superior to unreamed intramedullary nailing for femur shaft fracture in adults, but high quality RCTs were required to confirm the results. The metal tip of the Ruler denotes the driving end of the META-NAIL™ Retrograde Femoral Nail. IM rods are inserted into the bone marrow canal in the center of the long bones of the extremities. Intramedullary nail is a load sharing implant and plate is a load bearing implant, so stress shielding is less in IM nail and peri implant fractures are less. This rapid replacement of closed traction and cast techniques in North America was a controversial and contentious evolution in surgery. Thirty-eight percent of the fractures had hardware removed, most commonly because of pain. However, individual differences in femur cavity bring a challenge in designing well-matched IM nails and cause difficulties in IM nail implantation. The intramedullary nail is inserted over the guide wire into the distal fragment, to abut the femoral prosthesis. BO 212384 - Capitale Sociale € 4.700.000,00 - Iscritta nella sezione speciale delle PMI Innovative presso il Registro Imprese di Bologna Screws are placed above and below the fracture to hold the leg in correct alignment while the bone heals. We shall demonstrate now the steps for the insertion of a short proximal femoral intramedullary nail (PFNA). In most cases, neither a cast nor brace will be required post-surgery. The lateral decubitus position offers many advantages for intramedullary nailing of the femur. Keywords: Pertrochanteric fractures, Femur intramedullary nailing, Elderly fracture treatment, Gamma nail, Elos nail The most common surgery for a broken femur is called intramedullary nailing. With category-leading technology, intuitive instrumentation and market-leading support, we bring you the complete nailing portfolio you can trust. They come in various lengths and diameters to fit most femur bones. Gerhard Küntscher is credited with the first use of this device in 1939, during World War II, for soldiers … You should not drive, operate heavy machinery or participate in activities that Procedure: Femoral Intramedullary Nail Ø Pain Medication: You will be given a prescription for pain medication to be taken after surgery. Intramedullary (IM) nail implantation is currently the standard treatment for femoral intertrochanteric fractures. Via Armaroli, 21 - 40012 Calderara di Reno (Bologna, Italy) - tel. Intramedullary nail fixation of pediatric long bone fracture, particularly femoral shaft fracture, has revolutionized the care and outcome of these complex injuries. The rigidity of an intramedullary nail is proportional to the fourth power of the rod radius but is also dependent on the wall thickness. Intramedullary nails have a cloverleaf appearance on cross-section and are made of titanium, which has a lower rate of mechanical failure and improved biocompatibility. We continue to build upon our legacy of continuous design enhancements to ensure that our trusted portfolio meets your needs today and in the future. use radiolucent ruler to measure appropriate nail length Reaming. Inserting the Rod An intramedullary rod is inserted into the top of the femur and guided down through the fracture site and into the bottom portion of the bone. Preoperatively check the degree of the anterior bow of the femur on an x-ray of the uninjured extremity. Intramedullary (IM) rods are used to align and stabilize fractures. B. Kuntscher nail designed for closed nailing which has a curved, tapered tip, and is slotted throughout. The rod is fixed by screws at both ends and will keep the bone stable in order to ensure proper healing. Since the patient is in the supine position, the targeting device size 12.5mm reamer head for size 11mm nail) intramedullary nail A metal rod forced into the medullary cavity of long, weight-bearing bones (e.g., femur, tibia), which allows ambulation within weeks rather than months. The … One nail and 13 locking bolts broke. Intramedullary nails have a cloverleaf appearance on cross-section and are made of titanium, which has a lower rate of mechanical failure and improved biocompatibility. C.Grosse – Kempf nail D.Alta intramedullary locking nail for the femur. INTRAMEDULLARY NAIL OF FEMUR FRACTURE ACTIVITY Do not bear weight on the operative leg until permitted by your surgeon. Most intramedullary devices designed for proximal ulnar fractures are intended for simple, transverse injury patterns. Intramedullary nailing.

There were six infections, all occurring in closed fractures. The authors acknowledged potential bias in the included studies and their cautious conclusion is likely to be reliable. Results: Treatment with an intramedullary nail led to a union rate of 98.9%. (intramedullary nail) through the femur. A. Kuntscher nail, designed for open nailing. They may be used in the femur (thigh bone) or tibia (shin bone), for example. They are also called intramedullary nails. An intramedullary rod, also known as an intramedullary nail (IM nail) or inter-locking nail or Küntscher nail (without proximal or distal fixation), is a metal rod forced into the medullary cavity of a bone.IM nails have long been used to treat fractures of long bones of the body. Your child will be able to move his hip, knee and ankle on … If the tip of the nail comes to lie at the apex of the anterior bow, use a long nail or choose a plate.
