Learn the Percutaneous pinning of stable slipped capital femoral epiphysis with Synthes 73 mm cannulated screws surgical technique with step by step instructions on OrthOracle. Our e-learning platform contains high resolution images and a certified CME of the Percutaneous pinning of stable slipped capital femoral epiphysis with Synthes 73 mm cannulated screws surgical procedure.

Slipped capital femoral epiphysis (SCFE, SUFE) has an incidence of between 5-10 per 100,000 children per year, generally occurring during the adolescent growth spurt. The majority of slips are slowly progressive over weeks or months.

It is well accepted that the gold standard of treatment for mild and moderate (grade I/II) SCFE is percutaneous pin stabilisation. The same technique can also be used for grade III severe SCFE although long term results are less favourable.

For stable SCFE percutaneous pinning can be performed ‘freehand’ on a standard operating table as described here. The image intensifier remains static and the hip is flexed and externally rotated to achieve a lateral view.

Under X ray guidance a guide wire is passed across the central portion of the physis. A screw is then passed over the guide wire (6.0-8.0mm diameter) with the aim of engaging a minimum of 5 threads past the physis.

An associated techniques to deal with the later presenting slipped upper femoral epiphysis is dealt with on OrthOracle at https://www.orthoracle.com/library/dunns-osteotomy/

  • 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


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.
