Simple or unicameral bone cysts are common benign lesions found in children and adolescents and were first described by Virchow in 1891. It is important to distinguish them from more aggressive lesions such as aneurysmal bone cysts. Simple bone cysts (SBC) will frequently heal spontaneously once the adjacent physis has closed at skeletal maturity but lesions are still observed in some adults.

The majority of lesions are found in the metaphysis of long bones, the humerus being the most frequent site. However, any bone can be effected including the axial skeleton. Boys are more frequently affected than girls.

Simple bone cysts (SBC) are frequently asymptomatic unless they result in pathological fracture. The effects of such fractures is largely determined by their location, one of the most significant being around the hip where such injuries can result in malunion and damage to the blood supply to the femoral head unless appropriately managed.

Simple bone cysts can be treated by several modalities. More aggressive management is generally indicated for the proximal femur because of the consequences of femoral neck fracture.

  • 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.
