This study investigates the use of an automated impactor device in total hip arthroplasty versus manual malleting method and the physiological strain on the surgeon. This study will be a randomized, prospective, multicenter study involving fellowship-trained arthroplasty surgeons. Each participating surgeon will contribute data from 50 primary, elective THA cases, using the HAMMR powered impactor in 25 cases and manual impaction in 25 cases.

For cases that are randomized to the automated impaction HAMMR group, the surgeon will utilize an automated impactor device for impaction of the implant during total hip arthroplasty.
For cases that are randomized to the manual malleting group, the surgeon will utilize a mallet for impaction of the implant during total hip arthroplasty.

Physiological strain in the surgeon
Through the use of a Hexoskin vest worn by the surgeon, we will measure heart rate, heart rate variability, respiratory rate, minute ventilation, and energy expenditure to determine overall physiological strain on the surgeon during total hip arthroplasty.
Time frame: 1 day
Patient Adverse Events
Patient adverse events such as periprosthetic fractures intra- or postoperatively, intraoperative soft tissue injury, etc. will be recorded intra or postoperatively.
Time frame: 6 weeks
F-NRS
We will assess the Fatigue numeric rating scale (F-NRS) of surgeons after each case via survey.
Time frame: 1 day
