The use of time of flight camera for soft issue tracking during minimally invasive hip arthroplasty
نویسندگان
چکیده
Time of flight (TOF) cameras can guide surgical robots or provide soft tissue information for augmented reality in the medical field. In this study a method to automatically track the soft tissue envelope of a minimally invasive hip approach in a cadaver study is described. An algorithm for the TOF camera was developed and 30 measurements on 8 operational siti (direct anterior approach) were carried out. The results were compared to a manual measurement of the soft tissue envelope. The TOF camera showed an overall recognition rate of the soft tissue envelope of 75 %. Comparing the results from the algorithm to the manual measurements a significant difference was found (p>0.005).Recognizing the soft tissue envelope remains challenging. By further optimizing the algorithm and improving the measurement technique a a robotic navigation device for minimally invasive hip surgery could be developed.

Challenges of Plate Fixation for Vancouver Type-C Fractures after a Well-Fixed Hip Arthroplasty Femoral Stem
The fixation of distal femoral fractures (Vancouver type-C fractures) following a well-fixed hip arthroplasty femoral stem has become a challenging issue for orthopedic surgeons due to the inter-prosthetic biomechanical effects such as negative, positive, and torsional strain. Surgeons have applied a range of constructs to overcome these difficulties. To minimize the risk of inter-prosthetic fr...
متن کاملSoft tissue damage after minimally invasive THA
BACKGROUND AND PURPOSE Minimally invasive surgery (MIS) for hip replacement is thought to minimize soft tissue damage. We determined the damage caused by 4 different MIS approaches as compared to a conventional lateral transgluteal approach. METHODS 5 surgeons each performed a total hip arthroplasty on 5 fresh frozen cadaver hips, using either a MIS anterior, MIS anterolateral, MIS 2-incision...
متن کاملAuto-Gain Approach for Use with Time-Of-Flight Examination in Minimally Invasive Surgery
The use of time-of-flight cameras (TOF) in minimally invasive surgery is expected to grow over the next years. Some of the camera parameters like modulation frequency, integration time or focal point of the camera lens are still controlled by hand. In order to make the handling of a MUSTOF (Multi sensor TOF) endoscopic system more convenient the automation of these parameters with the help of p...
متن کاملCost effectiveness of minimally invasive total hip arthroplasty
CRD summary The objective was to examine the cost-effectiveness of two minimally invasive techniques for total hip arthroplasty, which were the mini-incision technique and the Minimally Invasive Solutions two-incision hip procedure. These were compared with conventional surgery. The authors concluded that the minimally invasive techniques were more effective and less expensive than the conventi...
متن کاملComputer-Assisted Musculoskeletal Surgical Navigational Orthopedic Procedure - 7/15
The goal of computer-assisted navigation (CAN) is to increase surgical accuracy and reduce the chance of malposition of implants. For total knee arthroplasty (TKA), malalignment is commonly defined as a variation of greater than 3° from the targeted position. Proper implant alignment is believed to be an important factor for minimizing long-term wear, risk of osteolysis, and loosening of the pr...
