What are the procedures of PFNA internal fixation

summary

Because we need to do PFNA internal fixation, so we want to do it by ourselves in advance. And before the operation, the doctor always emphasized what kind of posture I should use during the operation and what kind of operation process I should use. Let's talk about the operation steps of PFNA internal fixation.

What are the procedures of PFNA internal fixation

First: surgical reduction: the standard lateral position of the femoral neck is usually taken in anteroposterior and lateral position of the hip joint and when the C-arm is tilted up 20 degrees to evaluate the type of injury and fracture displacement of the patient, and the reduction is carried out by adjusting the traction bed; open reduction; the reduction must be completed before the fixation, and the reduction must be maintained when the internal fixation is installed.

Second: surgical approach: touch the greater trochanter, about 3cm above the greater trochanter, tilt from back to front to the distal end, consistent with the axis of the proximal femoral shaft and the anatomical shape of the anterior femoral arch, and make a 5cm incision. The fascia was cut parallel, and the middle arm muscle was separated bluntly according to the direction of muscle fiber.

Third: select the PFNA needle entry point: usually the top of the greater trochanter is inserted; it can be slightly deviated, and the 3 mm guide needle can be kept 5 degrees outward after insertion. Reaming: after the reamer is inserted into the opening, a protective device is placed on the outside of the reamer to prevent the reamer from deflecting to the outside and damaging the lateral cortex of the greater trochanter.

matters needing attention

Many people may know little about PFNA internal fixation at that time, so they may not have a very clear concept when they hear about this treatment. However, if patients want to do PFNA internal fixation, they must know something about the operation in advance.
