Consecutive patients with unstable trochanteric fractures (AO-classification 31.A.2 and A.3 only) were included and followed for 1 year. Lateral image showing guide wire with fractured femoral neck. The long gamma nail allowed early weight bearing and was effective in 85% of cases. 9 Actions. The morphological features of the nail are that it has a longer 35 to 40 mm nail and distal locking … Nail Determine nail insertion point and insert Guide Wire In the AP view, the nail insertion point is normally found on the tip or slightly lateral to the tip of the greater trochanter in the curved extension of the medullary cavity. Operative technique: • Anaesthesia: All the patients were operated under either spinal anaesthesia or epidural anaesthesia. Bone fractures are a very common orthopedic injury resulting from trauma and sudden loads or stresses applied to bones or a result from bones being weakened by certain diseases. Table 3:Long Vs Short PFN. Postoperative radiographic union time and modified Harris hip scores were used as major indicators for evaluating the effectiveness of surgery. 1 Proximal femoral nailing in such fractures is a challenging task even in the hands of experienced trauma surgeons. available for a proximal femoral nail.

Nail curves Long bones have curved medullary cavities Nails contoured to accommodate curves of bone Straight, curved or helical Average radius of curvature of femur - 120(±36) cm. Complete congruency minimizes normal forces and hence little frictional component to nail’s fixation. Downloads. Sir, I have read the article with great interest by Gadegone et al. Methods: Between June 2007 and October 2009, 41 proximal femoral fractures were treated, 22 with PFNA (group A) and 19 with reverse LISS‐DF plates (group B).

Clipping is a handy way to collect important slides you want to go back to later. Operative times can be reduced significantly when using the F1 Hip Nail. In the case of a malunion or non-union, a possible solution to the problem is by surgically inserting an intramedullary rod into the center canal (diaphysial) region of the injured bone and fixating it into place with screws.

Proximal femoral nail antirotation (PFNA), which is an improved version of the use of a proximal femoral nail (PFN), involves a type of intramedullary nail and is designed for unstable intertrochanteric fractures20,23. See our Privacy Policy and User Agreement for details. The Asia proximal femoral nail antirotation (PFNA-II) was specifically designed for Asian patients, which could be more effective than the regular proximal femoral nail antirotation (PFNA). Looks like you’ve clipped this slide to already. Objective: To evaluate and analyse the geometrical discrepancies between the proximal femur and two types of AO/Association for the Study of Internal Fixation (AO/ASIF) Proximal Femoral Nail Anterotation (PFNA/PFNA-II) using computed tomography (CT)-based analysis in Asian patients, and its implication in lateral cortical impingement during reduction intra-operatively in subtrochanteric fractures. Immobilization from casts may not be enough to completely heal the fracture if a malunion (when both ends of the fractured bone misalign) occurs and/or if a non-union (when the fracture gap is too large and the fractured ends cannot re-attach to one another) occurs. The same proximal femoral nail anti‐rotation devices and the same surgical procedures were applied to all patients. Alternatives Determine the nail length by the procedure above on the uninjured leg before draping (unsterile) or compare the length of two identical SynReam reaming rods 2.5 mm (352.032) or use the depth gauge (351.717 and 351.719) in combination with the SynReam reaming rod 2.5 mm, length 950 mm (352.032).  Due to its position close to the weight-bearing axis the stress generated on the intramedullary implants is negligible. Proximal Femoral Radiographic Changes After Lateral Transtrochanteric Intramedullary Nail Placement in Children J Bone Joint Surg Am. Bone fractures are either a complete or partial break in a bone and in some cases a simple cast to immobilize the injury site is not enough to completely heal the fracture. proximal femoral nail antirotation (PFNA-long). Preoperative planning , decision making , post op rehab, guidelines , evidence based approach. Cairo- Egypt. More than 250,000 femur fracture patients are seen per year in the U.S. on average. Proximal Femoral Nail Antirotation Surgical Technique DePuy Synthes 11 2 Confirm nail length and diameter Instrument 309.602 Radiographic Ruler for PFNA The required nail length must be determined after reduction of the femoral fracture. Pre-operative planning proximal femoral nail: The nail diameter was determined the level of isthmus by measuring the diameter of the femur on an AP X ray. A study population was selected and was carried out with a total of 25 patients (male: 20, female: 5) treated with proximal femoral nail from the year 2015-2016. 1. Biomechanical cadaveric studies demonstrated that PFNA fixation using a helical blade was better compared to the sliding hip screw.

Position the C-arm for an AP view of the proximal femur. Mohamed Abulsoud (M.D) The exact location of the skin incision depends on the type of insertion handle / type of nail used. 1. Make a 3-5 cm skin incision several centimeters proximal to the tip of the greater trochanter. Methods: From June 2006 to December 2013, 139 cases (35 women, 104 men; mean age 48.8, range, 18−86 years) of long-segment femoral fracture in middle-up part were treated with long proximal femoral nail antirotation (PFNA, 320–380 mm) by minimally invasive percutaneous fixation and autogenous iliac bone graft.

ACA ENGINEERING However, proximal femoral nail antirotation was designed according to the geometric proportions of the White population, and it is known that important differences exist between Asians and Americans with regard to femoral geometry. See our User Agreement and Privacy Policy. Advantages of proximal femoral nail. Proximal femoral nail [8-10]: Table 3. 2019 Oct 29;20(1):500. doi: 10.1186/s12891-019-2793-8. The proximal femoral nail antirotation (PFNA), designed by AO, is an intramedullary device with a helical blade rather than a screw for better purchase in the femoral head and was tested in a clinical study. Complex proximal femoral fractures are difficult to treat with all implants demonstrating high complication rates. proximal femoral nail (PFN) and proximal femoral nail antirotation (PFNA). Malpositioning of the implant should be avoided, as this was the leading cause of failure. 0.

The TFN-ADVANCED Proximal Femoral Nailing System (TFNA) 235 mm (DePuySynthes) and Proximal Femoral Nail Antirotation (PFNA)-II 240 mm (DePuySynthes) were developed to achieve better stability for patients with trochanteric hip fractures without increasing surgical time and blood loss. Do we need a proximal femoral nail ? OBJECTIVE: To compare the effectiveness of proximal femoral nail anti-rotation (PFNA) between in the supine "scissors" position and in the lithotomy position for treating femoral intertrochanteric fractures of old patients. The instruments have been developed through clinical trials to be simple to use and enable the screws to be easily aligned in the femoral head.  limits the surgical insult to the … BY ALEX BERTINO, COREY VAN DE HAY, ANDREW HNAT This image shows the first guide wire being inserted through the lateral cortex.
