How long does PFN surgery take?
Results: The average duration of surgery, i.e. starting from the skin incision until the suture of the wound, was in DHS 47 min., in EN 52 min., in 130 degrees angled blade plate 54 min., in PFN 58 min. and in Gamma nail 70 min.
Is PFN a major surgery?
In conclusion, the PFN is a good minimal invasive implant of unstable proximal femoral fractures, if closed reduction is possible.
What is the difference between DHS and PFN?
Conclusion: PFN is better than DHS in type II intertrochanteric fractures in terms of decreased blood loss, reduced duration of surgery, early weight bearing and mobilization, reduced hospital stay, decreased risk of infection and decreased complications.
What is PFN a2 surgery?
PFNA2 (Proximal femoral nail antirotation for Asia) has been developed especially for Asian patients. The treatment of proximal femoral fractures in geriatric osteoporotic patients continues to be a challenge in orthopedic trauma.
How long is recovery after femur surgery?
Recovery most often takes 4 to 6 months. The length of your recovery will depend on how severe your fracture is, whether you have skin wounds, and how severe they are. Recovery also depends on whether your nerves and blood vessels were injured, and what treatment you had.
Why is PFN done?
The proximal femoral nail (PFN) is an osteosynthetic implant designed to treat proximal femoral fractures in the trochanter area with a closed intramedullary fixation method.
What is Z effect in PFN?
The Z-effect involves the lateral migration of the inferior screw, varus collapse of the fracture and perforation of the femoral head by the superior screw. The reverse Z- effect involves the lateral migration of the superior screw accompanied by the medial migration of the inferior screw.
What is a proximal femur fracture?
Proximal femoral fractures are a heterogeneous group of fractures that occur in and around the hip. The commonest type of fracture in this region is the femoral neck fracture. They can occur anywhere between the joint surface of the femoral head and the upper shaft (proximal diaphysis) of the femur.
How does a sliding hip screw work?
The screw is a large cancellous lag screw that can glide freely in a metal sleeve. The sleeve is attached to a plate which is fixed to the lateral femoral cortex with screws. Weight bearing thus causes the femoral neck to impact on the femoral metaphysis, producing dynamic fracture compression.
What is the difference between PFN and Pfna?
PFNA has a superior performance over PFN in the setting of osteoporosis, which is attributed to compaction of cancellous bone by the helical blade. Nevertheless, it must be remembered that no implant design can compensate for poor reduction or poor implant placement in these fractures.
How do you get a PFN?
If you are using the PFNA, insert the 11.0 drill bit over the guide wire and open the lateral cortex to 11 mm. In a young patient, drill the neck with the 11.0 mm reamer to make room for the helical blade. In the elderly, stop once you have opened the lateral cortex.
What is femoral nail?
Prophylactic femoral nailing is a procedure to stabilize the femoral bone that has become weak due to the presence of a tumor. The procedure involves passing a nail or rod through the intramedullary canal or central canal of the bone to reinforce the bone along its entire length.
What is the difference between PFN and Pfna?
PFNA has a superior performance over PFN in the setting of osteoporosis, which is attributed to compaction of cancellous bone by the helical blade. Nevertheless, it must be remembered that no implant design can compensate for poor reduction or poor implant placement in these fractures.
What is Z effect in PFN?
The Z-effect involves the lateral migration of the inferior screw, varus collapse of the fracture and perforation of the femoral head by the superior screw. The reverse Z- effect involves the lateral migration of the superior screw accompanied by the medial migration of the inferior screw.

When do you use dynamic hip screws?
A dynamic hip screw is performed where the neck of femur has been fractured and where there is a good chance that it will heal if held in place by internal fixation. The internal metal work consists of a large screw placed in the head of the femur and a plate held onto the side of the femur by several smaller screws.

What are the benefits of surgery?
The main benefits of surgery are that you will only need a short stay in hospital and you will be able to use your leg sooner. Surgery will also make sure your bone heals in a good position.
What is a femoral nail?
Femoral nailing is an operation to fix a broken femur using a metal rod. The metal rod is called a femoral nail (also called an intramedullary or interlocking nail) Your surgeon has recommended femoral nailing to treat your broken femur. However, it is your decision to go ahead with the operation or not.
Can a femoral shaft fracture be fixed?
A femoral shaft fracture can be treated in traction (using a heavy weight fixed to the leg to pull the bones into position until they heal). However, some fractures are difficult to hold in a good position without surgery. If you have an open fracture, you will almost certainly need an operation. Your surgeon can sometimes fix your femoral shaft fracture with an external fixator or a plate and screws instead of a femoral nail. They will explain why they recommend femoral nailing for your fracture.
What is the correct nail for PFN?
This surgical technique is based on the PFN standard surgical technique. In order to follow the correct procedure, please refer to the respective steps in the standard technique. This part only shows the steps regarding insertion and distal in- terlocking of the long PFN which differ from the standard technique. Usually, the 130° nail is suitable for most indications. In some cases, however, the use of a 125° nail may be indicated.
What angle is standard PFN?
Take an AP X-ray of the unaffected side preoperatively. De- termine the CCD angle using a goniometer or the preopera- tive planning template (no. 036.588). Standard PFN is available in 125°/130°/135°.
How to insert a nail into a femoral opening?
Carefully insert the nail manually as far as possible into the femoral opening. Slight twisting hand movements help inser- tion. If the nail cannot be inserted, select a smaller size nail diameter. Insertion can be supported by light blows with the synthetic Hammer (399.505) on the mounted protection shield of the insertion handle.
How to visualize proximal femur?
Position patient supine on an extension table or a radio- lucent operating table. Position the C-arm of the image in- tensifier in such a way that it can visualize the proximal fe- mur exactly in the lateral and AP planes. For unimpeded access to the medullary cavity, abduct the upper part of the body by about 10–15º to the contralateral side (or adduct the affected leg by 10–15º).
What is ASLS surgical?
Note: ASLS, the Angular Stable Locking System, is indicated in cases where increased stability is needed in fractures closer to the metaphyseal area or in poor quality bone. For more details regarding the intramedullary fixator principle, please consult the ASLS surgical technique (DSEM/TRM/0115/0284) and concept flyer (036.001.017).

Why do we need pulmonary function tests before surgery?
Pulmonary function tests before surgery have been ordered for decades to help assess the risk of surgery. The elegance of the test is related to its simplicity and its extreme low risk. Originally, preoperative testing of pulmonary function was used to assess the risk of pulmonary resection for tuberculosis.
What is preoperative spirometry?
Preoperative spirometry before abdominal operations: a critical appraisal of its predictive value.
Is pulmonary function related to thoracotomy?
suggested that abnormal pulmonary function was strongly related to outcomes of thoracotomy. Several other studies in the 1960s and 1970s supported this concept.
Is it necessary to assess the risk of surgery?
Assessing the risk of surgery is a necessary part of the presurgical evaluation as the physiologic stress of anesthesia and surgery can be considerable. The carefully rendered medical history and physical examination are the time-honored and proper first steps to evaluate the patient being considered for surgery.
Is spirometry used before surgery?
Spirometry before these procedures is very unlikely to be of help to decide whether the surgery should be done or to alter perioperative management. For surgeries of inherently higher pulmonary risk such as upper abdominal procedures, spirometry should be used rarely, given the current state of the literature.
