Powered Impaction and Broaching in Elderly Total Hip Arthroplasty

Condition(s) studied

Investigational drug(s) / intervention(s)

Total Hip Replacement with Automatic impaction and broaching device: Total hip replacement with the use of an automatic impaction and broaching device

Total Hip Replacement: Total hip replacement without automatic impaction and broaching

Study summary

Placing the parts of a hip replacement requires substantial force. This can lead to additional stress on the surgeon as well as the bone. A device was developed to help reduce this stress. This study aims to see whether this device impacts implant positioning and the surrounding bone in patients 70 years and older. It also will investigate surgeon efficiency and how patients walk after surgery.

Eligibility

Primary outcome measure(s)

• Incidence of Periprosthetic fracture — 90 days
  Intraoperative or early postoperative femoral/acetabular fractures in patients 70 years or older, when compared to traditional manual techniques in DA THA. * Measured via intraoperative reporting of fracture by surgeon (Yes/No), the postoperative CT scan by the radiologist (Yes/No) (CT scan performed within 1 week of operation) and by the radiograph at 3 months/90 days by the surgeon (Yes/No) * Outcome end point: 3 months/90 days (i.e. no fracture within 90 days of surgery)
