Operative times can be reduced significantly when using the F1 Hip Nail. 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. 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.

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. METHODS: A retrospective study was performed on 58 patients with femoral intertrochanteric fractures treated with PFNA between January 2013 and January 2015. 1 Proximal femoral nailing in such fractures is a challenging task even in the hands of experienced trauma surgeons. The neck shaft angle was measured in unaffected side in AP X ray using goniometer. Lecturer of orthopedic surgery  limits the surgical insult to the … Downloads. Sir, I have read the article with great interest by Gadegone et al.

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.

The same proximal femoral nail anti‐rotation devices and the same surgical procedures were applied to all patients. 1. Surgical TreatmentSurgical Treatment 23. Nail 0. available for a proximal femoral nail. 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. 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. Cairo- Egypt. 1. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Proximal Femoral Nail – Standard PFN and long PFN 12 1. The proximal femoral nail anti-rotation (PFNA), a modification of proximal femoral nail (PFN), was introduced in 2003, which features a helical blade. The long gamma nail allowed early weight bearing and was effective in 85% of cases. 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. Objective: To compare the effects of proximal femoral nail antirotation blade (PFNA) and reverse less invasive stabilization system‐distal femur (Liss‐DF) systems in the treatment of proximal femoral fractures. According to Sharma and Mahajan, PFNA has a superior performance over PFN in the setting of osteoporosis, which is attributed to compaction of cancellous bone by the … Make a 3-5 cm skin incision several centimeters proximal to the tip of the greater trochanter. Proximal femoral nail anti-rotation versus cementless bipolar hemiarthroplasty for unstable femoral intertrochanteric fracture in the elderly: a retrospective study BMC Musculoskelet Disord. 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.

Postoperative radiographic union time and modified Harris hip scores were used as major indicators for evaluating the effectiveness of surgery. c) Maintenance of controlled fracture impaction. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Biomechanical cadaveric studies demonstrated that PFNA fixation using a helical blade was better compared to the sliding hip screw.

Such fixation allows proximal fragment fixation with a large sliding screw traversing obliquely through the nail in to the neck of femur and distal fragment is stabilized in longitudinal and rotational axis by distal trans-implant screw fixation. 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. See our User Agreement and Privacy Policy. 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. proximal femoral nail (PFN) and proximal femoral nail antirotation (PFNA).

Evidence based approach • ILO • Decision making • Preoperative planning • … 0 Number of Embeds. Lateral image showing guide wire with fractured femoral neck. Results. Proximal Femoral As shown, this lies on the proximal extension of the bowed axis of the femoral shaft. Position the C-arm for an AP view of the proximal femur. Proximal Femoral Nail Antirotation Technique Guide DePuySynthes 11. PROXIMAL FEMORAL NAIL  Have been shown to prevent the fractures of the femoral shaft by having a smaller distal shaft diameter which reduces stress concentration at the tip. 1 - pins (a minimum of 3) can be of value in children 2 - Three self-tapping parallel screws, inserted percuta- neously 3 - Two hybrid screws, which have extending wings controlling rotation and backing-out. Proximal femoral fractures Evidence based approach Mohamed Abulsoud (M.D) Lecturer of orthopedic surgery Faculty of medicine – Al-Azhar university Cairo- Egypt 2. Compared to PFNA, whether PFNA-II is associated with shorter operative time and lower rates of complications is unknown. 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). Proximal femoral fractures 1. See our Privacy Policy and User Agreement for details. The mediolateral angle of the implant amounts to 6º. Advantages of proximal femoral nail. Mohamed Abulsoud (M.D) 2019 Oct 29;20(1):500. doi: 10.1186/s12891-019-2793-8. 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). The exact location of the skin incision depends on the type of insertion handle / type of nail used. d) Acts as a buttress to prevent shaft medialisation . 1. 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. b) Shorter lever arm can decrease tensile strain on implant and risk of implant failure. radiological outcome of subtrochanteric fracture treated with proximal femoral nail. Faculty of medicine – Al-Azhar university 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).
