Summary
This case study shows that global positioning system (GPS)-navigated anatomic total shoulder arthroplasty (aTSA) can achieve accurate component placement and good short-term outcomes in active patients with severe glenohumeral osteoarthritis.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Radiology
Background:
- Severe glenohumeral osteoarthritis significantly impacts shoulder function and quality of life.
- Conservative management often fails in active individuals with advanced joint degeneration.
- Anatomic total shoulder arthroplasty (aTSA) is an option for end-stage shoulder arthritis.

01:30Introduction to Global Positioning System
The Global Positioning System (GPS) revolutionized positioning on Earth, providing precise location data through satellite ranging. The GPS system was developed in 1978 by the U.S. Department of Defense for military use, and it became available for civilian applications in 1983, transforming fields including navigation, fleet management, and time synchronization for telecommunications systems.GPS consists of satellites in medium Earth orbit, about 20,200 kilometers above the surface,...
01:28Field Application of Global Positioning System
The Global Positioning System (GPS) has become an indispensable tool in fieldwork, offering unparalleled precision and efficiency for surveying, navigation, and infrastructure development. By harnessing signals from a constellation of satellites, GPS receivers determine the location of objects with remarkable speed and accuracy, often completing calculations within a second.Advantages of Modern GPS TechnologyContemporary GPS receivers are designed to meet the practical demands of field...
01:30Design Example: Identifying the Locations of Monuments in the Field Using Global Positioning System Device
Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point served as...
