PerfHip Fit Log Book

Design Studio 1

  • Met group members

  • Read problem scenario and examined x-rays

  • Diagnosed patient with Perthe's disease through research and help of professionals

Group Meeting 1

  • Designated leader, second in command, and completed Gantt chart

  • Preliminary materials selection

  • Chose ceramic on ceramic bearings to reduce wear particles to promote bone growth

  • Realized we needed materials with low elastic modulus to prevent stress shielding - will have to change bearing material later since ceramic has high stiffness

  •  Decided to use hollow titanium filled with foam for stem material - low elastic modulus but strong

Design Studio 2

Design Studio 3

  • Completed preliminary design analysis calculations to prepare for Python program that will be coded later

Group Meeting 2

  • Decided on who is doing what for Python program

  • Decided on who is modelling what part of the hip implant

  • Discussed possible design concepts (ribbed femoral stem, custom neck to regain 1cm height deficit, etc.)

  • Discussed surgical fixation (leaning towards uncemented)

  • Decided we needed to research new bearing/liner material by next meeting

Design Studio 4

  • Finalized design materials and concept

Group Meeting 3

  • Python programming session!

  • Aided group members with Python programs by providing hints and constructive feedback

Group Meeting 4

  • Finished Python program

  • Started on preliminary Inventor designs

Design Studio 5

  • Edited and finalized Python program

  • Measured and constructed implant measurements based on representative bone models and actual 3-D bone models from CT scans

Group Meeting 5

  • Finished Inventor models and finalized assembly

  • 3-D printed prototype

  • Prepared written content for poster

Group Meeting 6

  • ​Started creating poster

  • Started writing presentation script

Group Meeting 7
