Learn the Navigated coned hemi-pelvis endoprosthesis (Stanmore METS, Stryker) with dual mobility acetabulum (Avantage, Zimmer Biomet) and modular proximal femoral endoprosthetic replacement with trochanteric reattachment (Stanmore METS, Stryker) surgical technique with step by step instructions on OrthOracle. Our e-learning platform contains high resolution images and a certified CME of the Navigated coned hemi-pelvis endoprosthesis (Stanmore METS, Stryker) with dual mobility acetabulum (Avantage, Zimmer Biomet) and modular proximal femoral endoprosthetic replacement with trochanteric reattachment (Stanmore METS, Stryker) surgical procedure.
Computer navigated tumour surgery is regarded as one of the major developments in the field of orthopaedic oncology of the past decade. Navigation permits pre-operative three-dimensional resection and implant planning to be combined with intra-operative imaging. These advantages have resulted in its growing incorporation into routine practice since its first application in 2004. In this case I describe the use of navigation to aid endoprosthetic reconstruction of the pelvis and acetabulum using the Stanmore coned semi-pelvis (‘ice cream cone’) endoprosthesis (http://www.stanmoreimplants.com/downloadpdfs/06.METS%20Coned%20Hemi-Pelvis%20Information%20and%20Surgical%20Procedures%20(File%20Size%20-%201MB).pdf).
This implant is ‘off the shelf’ and utilised in orthopaedic oncology to reconstruct the peri-acetabulum due to bone loss due to tumour involvement. Pelvic anchoring is provided by a fixed hydroxyapatite stem which can augmented with bone cement and reinforced with screws to achieve a stable acetabular reconstruction. Having created the acetabulum, a suitable acetabular cup is cemented into the cone for use with a total hip replacement. Recent evidence has confirmed that dual-mobility articulations reduce the risk of dislocation with hemi-pelvic endoprostheses, so this case describes the use of a cemented dual-mobility acetabular cup and bearing.
Metastatic bone disease commonly presents to the orthopaedic surgeon. Bone is the most common site of metastasis. Approximately 60% to 70% of patients with breast cancer develop bone metastases during the course of their disease. Skeletal related events (SREs: pathological or impending fracture, hypercalcaemia, spinal cord compression, severe pain) may require surgery and/or radiotherapy to palliate pain and to maintain both the capacity to walk and quality of life. Due to advances in management of common malignancies, particularly breast and prostate carcinoma, patient survival has been extended to the point that these are now considered chronic diseases rather than terminal diseases. Consequently, the prevalence of metastatic bone disease continues to escalate.

- 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.
