A few caveats . . . be sure to clean the screws really well with alcohol prior to installing. Hopefully they are stainless, less risk of issues due to internal rusting and stiff joints*. Use a good impact driver as it will run the screws in faster, so less chance you'll stop half way due to the intense pain. Speaking of which, biting on a bullet or old leather belt can be helpful (worked during the Civil War, I hear).
Once you get this under your belt, so to speak, you'll be ready for the DIY appendicitis kit. *And speaking of stiff joints, the DIY penile implant kit should be swinging into the marketplace any day now - look for both on your supermarket shelves (replacing food items that used to be there).
