Our e-learning platform contains high resolution images and a certified CME of the Supinator to Posterior Interosseous Nerve Transfer (S-PIN transfer) surgical procedure.
Motor nerve transfer surgery uses an expendable nerve branch or redundant nerve fascicle from within a functioning nerve to transfer directly to the terminal motor branch of a paralysed muscle with a more important function. The nerve co-aptation is close to the target muscle and reinnervation distances are therefore short. The Supinator to Posterior Interosseus nerve transfer (S-PIN transfer) is indicated in isolated lower brachial plexus injuries (C8/T1), degenerate C8 motor radiculopathy or in mid-cervical tetraplegia. The aim is to restore digit extension using medial and lateral branches of the PIN to supinator innervated from the C6 root. These branches are implanted to the adjacent PIN (C8 digit extension) through either an anterior or a posterior approach to the PIN. The supinator is decompressed as part of the procedure when performed through the anterior approach and this technique is illustrated here.

- 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.
