Right now as a 3rd year you should be reading McGlamrys. The new one is great. Very easy to read, better pictures, less history, less boring. Read the chapters you think you should be reading. 6 things to focus on: Anatomy (numero uno), antibiotics/bugs/doses, internal fixation, trauma and classifications, Osteo, Imaging. You don't need to be reading individual steps on how to do a triple (as a 3rd year).
You need to understand principles of fixation (Rockwood and Green is my favorite for this), types of plates, how to achieve compression, steps in screw fixation...
You need to know Ankle, Calc and Talar classifications, how to fix them, complications....
You need to know how to recognize OM, from physical signs and symptoms to x-ray/MRI/bone scan....
You need to know basic dosages and when to use Zosyn, Vanc, Ancef, Keflex, Cipro, Levo, Clinda, Bactrim, Zyvoxx, Linezolid, Invanz. Understand Staph, Strep, MRSA and psuedo ( and anaerobes)...
You need to know anatomy. Anatomy, Anatomy and Anatomy. If you understand anatomy, you can answer 75 percent of questions asked in the OR. Much of it you need to see in surgery to really grasp, but you can understand location and function from a book.
You need to understand principles of bone healing, wound healing and tendon healing...time frames, stages....
You need to understand flatfoot - how to evaluate plane of deformity based on X-rays, suggest procedure that will correct that plane
You need to know how to read an X-ray. I know every program is different, but I found the quickest, fastest way is too combine views and make one profound statement. Instead of going through your AP and saying you see lateral displacement of the MT fracture, then moving on to your oblique, say "I am looking at both an AP and MO. The 2nd MT has an extra-articular midshaft spiral fracture with plantar and lateral displacement." It takes time to get comfortable. Any chance you have, ask a resident if you can read it quickly (your best judgement on if there is time...). Say what you see, it is that simple. Don't get caught up saying "There doesnt appear to be any soft tissue emphysema." if there isnt any. Give the pertinent positives. Short and sweet. If they want more, they will ask. Explain what you see, thats all. I used to get caught up in trying to say all the fancy words and try and sound smart and the like.
You need to know how to look at an X-ray and know what procedure was done based on where the screws/plates/staples are.
This is the type of thinking you need to be doing as a 3rd year.
Edit - forget part of flatfoot and last sentence also.
