He was consented for internal fixation, with a nail. That is of course routinely referred to as informed consent, and if you're being appropriately thorough (not pedantic), the information required to make a balanced decision would have included the pros and cons of conservative treatment in a cast or brace. Traction, external fixation, plating are all in the mix, but lets stick to conservative v nailing.
Is there any published evidence worth having?
Why, yes there is.
What do you think the incidence of knee pain is after tibial nailing? Patients frequently mention it, and it can be a real problem. 10% would be OK, 20% perhaps. Well, in a very good study from Vancouver's ace trauma unit, of 56 patients at a minimum of 12 years, it was 73%. That's knee pain, related to the nail, not fracture site pain. Of course, there are quite a few other potential problems with surgery and anaesthesia.
OK, there are still plenty of arguments for nailing, but I actually knew one surgeon who put circular frames on instead of nailing, because of anterior knee pain. A little extreme, but it makes the point. Here's the Vancouver paper.
But is there any good evidence for conservative treatment in this group of isolated fractures?
How about nearly 1000 patients treated with early functional bracing? Sarmiento's study is pretty impressive, with acceptable angulation, shortening and union rates. I won't go through it all, read it for yourself. Not the same follow up, but the point is, while each treatment has its own advantages and disadvantages, they are both valid, and should both be available to the patients. We have emphatically not 'moved beyond' tibial bracing because of our brilliance at tibial nailing.
For what it's worth, in these isolated closed fractures, I would indeed fix those with an intact fibula - they nearly always angulate too much - and the very comminuted ones, plus the compartment syndromes. Everything else is up for discussion. Nailing is often 'fix and forget', and casting/bracing is not necessarily easy, but that's not the point. I've seen plenty of complications of nailing. It's not always in the patient's best interests.
Back to the trauma meeting. No-one seemed able to quote a paper on either treatment. When asked "what would you have done if it was your tibia?", only one person spoke up. It was the anaesthetist, who'd had a problematic infection after orthopaedic surgery. "Stick it in a cast" was her response.
And if consent was truly informed, a few other patients might well join her.
I always fix them in polytrauma, personally |
