Learn the Cannulated Hip screws (Asnis III – Stryker) for fixation of intracapsular neck of femur fracture surgical technique with step by step instructions on OrthOracle. Our e-learning platform contains high resolution images and a certified CME of the Cannulated Hip screws (Asnis III – Stryker) for fixation of intracapsular neck of femur fracture surgical procedure.

These fractures occur predominantly in a bimodal distribution of young adults and the edlerly. In the young they are associated with high energy trauma, most often polytrauma. The majority of fractures however occur in the elderly. They are associated with groin and proximal thigh pain.

In the case presented no fracture was seen on plain radiographs but suspected and the undisplaced intracapsular fracture was diagnosed on MRI.

This presentation highlights a somewhat novel technique for performing cannulated screws through stab incisions. It is reliable and highly reproducible.

This technique is less invasive than the standard technique most are taught, potentially decreasing wound complication rates and length of stay, however it does need to be performed well and in the correct patient.

Ideally this should be read in conjunction with my published OrthOracle techniques : Stryker Omega Dynamic Hip Screw for extra-capsular neck of femur fracture and Exeter Trauma Stem for Intracapsular Neck of Femur Fracture – Stryker.

  • 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.

Our content is designed for both Surgeons in independent practice and Surgeons in training.
