Our e-learning platform contains high resolution images and a certified CME of the Proximal femoral varus osteotomy using angled Blade plate fixation surgical procedure.

There are several indications for proximal femoral varus osteotomy. These include the management of developmental dysplasia of the hip, Coxa valga, hip subluxation in cerebral palsy and containment procedures for Legg Calve Perthes disease.

Containment procedures in Perthes can be either femoral or pelvic. Pelvic operations include Salters osteotomy, Shelf procedure and triple pelvic osteotomy.

Femoral varus osteotomy is a simpler operation than pelvic osteotomy. However, varus osteotomy does result in shortening of the leg (which is generally already short in Perthes disease). This can be mitigated to an extent by performing an opening wedge osteotomy rather than a closing wedge.

In the case of Perthes disease varus osteotomy is generally utilised between the ages of 7 to 10 years. The varus introduced by the osteotomy may remodel in this age group. In older children the varus remains and many will require a valgus osteotomy once the disease process has resolved to reverse the limb shortening. In older children pelvic procedures such as triple pelvic osteotomy provide good containment without limb shortening.

  • 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.
