“It’s just a DHS”! is something I have heard many times from consultant colleagues through to junior trainees alike.

It is never “just a DHS”. In my opinion these operations can be difficult, fracture reduction may be challenging, maintaining reduction whilst performing the operation can catch out the unwary and malpositioning of implants can lead to failure. Additionally constructing the kit used for surgery (especially if an unsupervised junior nurse is present) is often overlooked.

Neck of femur fractures for the most part are in frail, elderly patients with osteoporosis and significant comorbidities. Getting it right first time is paramount.

The following operation is a fixation of an extra-capsular neck of femur fracture using a Stryker Omega Dynamic Hip Screw (or sliding hip screw).

The photographs were taken in real time and show that this operation can be challenging but as a result will show you some of the actual situations and decisions

I have taken some additional slides outside of the operation to show you how to construct and use the Stryker DHS set. Each company’s system is slightly different and I would strongly encourage the reader to review the op-tech before embarking on any surgery, especially as the supervisor may think this is just a DHS!

  • Each operation and the questions associated become a named course in the CPD section
  • The operative technique itself is read as a lesson as is any company implant information if this is being assessed.
  • You’ll need to tick the box to confirm this has been done and can do this immediately if you have already read the op tech.
  • The vast majority of operations have a 10-15 MCQ quiz covering all aspects of the decision making and the technique
  • There are four possible answers of which one is correct (or on occasion more correct) than the others.
  • There are additional quiz modules on the surgical steps, the implants and problem cases being added continually
  • The course is completed once all the lessons are read and quizzes submitted and passed.
  • On successful completion of each quiz you will receive validated CPD points that add to the certificate in your CPD folder.
  • Your dashboard also will contain a record of the time you have spent logged onto and using the site.
  • The timer suspends after 5 minutes though if there is no activity.
  • When you restart you will resume at the same point in the module.
  • Once you have completed each quiz you will need to feedback on the module first then click “submit” and your paper will be marked.
    The pass mark is 75%.
  • If you fall below this level you will be directed back to re-read the slides where you’ve tripped up.
  • Once these have been read you can re-do just the questions you failed on.
  • Once you have passed the quiz you can return at a future stage & resit .

CPD Points:

  • Operation Quiz – 1 CPD point
  • Surgical steps Quiz – 1/4 CPD point
  • Implants Quiz – 1/4 CPD point
  • Problem case Quiz – 1/2 CPD point

One CPD point equates to one hour of academic activity
