Chondrosarcoma (CS) is the second most common primary bone tumour and the most common in adults. These range from low to high grade malignant cartilage tumours which may metastasise to the lungs. They are relatively insensitive to chemo or radiotherapy meaning that surgery is the principal intervention. Five year survival ranges from 99% for low grade to 24% for dedifferentiated chondrosarcomas. Resection of a tumour from the proximal femur requires reconstruction of the large bone and soft-tissue defect. Achieving adequate surgical margins to ensure the tumour is excised-bloc is the guiding oncological principle to avoid local recurrence.
Endoprosthetic replacements of the proximal femur are one of the most common limb-salvage procedures undertaken to reconstruct massive bone defects secondary to tumour, trauma or infection. The complications of such surgery from a systematic review include dislocation (5.8%), prosthetic joint infection (5.2%), local recurrence (4.7%) and peri-prosthetic fracture (0.6%). These are both reliable and durable implants that offer immediate mobility and return to function; however in the long-term complications and failure mean that ten year endoprosthesis survival without revision surgery is approximately 75%.

- 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.
