The investigator's plan to quantify the physiologic impact of orthopaedic surgery on the surgeon and operating team.

The prevalence of musculoskeletal pain among orthopaedic surgeons is inordinately high. Poor surgical ergonomics and physiological stress have been shown to impair surgical performance and cause injuries. Various approaches, techniques and instruments have been designed to improve surgical outcomes for patients. There has been nominal research in the area of occupational hazards such surgeries impose upon the surgeon. Several studies have demonstrated a higher risk of cervical spondylosis and rotator cuff tears amongst surgeons. However, little has been studied on the impacts of some of these approaches, techniques, and instruments on surgeons' physiologic measures.

The investigator's will use The Hexoskin Smart Vest to capture physiological data from surgeons during the study.
