Ankle arthrodesis is an established treatment for painful, end-stage ankle arthritis. Over the last century, a number of operative techniques have been popularised, with modifications reflecting technological advances. These have ranged in methods of fixation from the Charnley external clamps through to all manner of crossed/parallel screw fixation techniques.
However, managing deformity, poor bone quality or bone loss remain difficult issues to resolve using traditional techniques. As a result, biomechanical studies into the properties of angle-stable devices such as blade plates and non-anatomic locking plates have found some mechanical advantages over screws in stabilising an ankle arthrodesis, thus potentially offering a solution. Therefore, in Sheffield, Mr Mark Davies and Mr Chris Blundell developed a new anatomically contoured, fixed angled lateral locking ankle arthrodesis plate – the Ankle Fix 4.0. Manufactured by ZimmerBiomet, we have successfully used this device for open ankle fusion surgery especially in more challenging clinical situations. The rationale behind the plate design was formed after both authors had gained experience using an inverted PHILOS plate. It was felt that a set of divergent screws within a low-profile talar section would offer a significant pull-out strength in cancellous bone and similarly that convergent screws in the tubular, cortical bone would provide robust tibial fixation. These screws were specifically designed to be 4.0 mm in size to allow clustering of the screws which contrasts with the larger, less versatile plate designs that were on the market at the time of design in 2009.
With limited literature on the wealth of new locking ankle fusion plates, the plate designers present these results and discuss their large series in the December 2017 issue of the journal Techniques in Foot and Ankle Surgery.

- 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 .
- 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
Welcome to the Professional Development question section. The objective of taking these tests is to demonstrate that you have understood all aspects of the assessment and management of patients requiring surgical intevention. On successful completion you will receive a certificate accredited by both the Royal College of Surgeons of both England and Edinburgh as well as the British Orthopaedic Association.
