Assessing the outcomes of spine surgery using global positioning systems

Area of Science:

• Orthopedic Surgery
• Rehabilitation Medicine
• Biomedical Engineering

Background:

• Traditional surgical outcome studies face challenges with subjective measures, patient expectation shifts, and secondary gains.
• Objective outcome assessment is crucial for evaluating surgical procedure effectiveness and patient recovery.
• Developing valid, objective outcome measures remains a significant challenge in surgical research.

Observation:

• A pilot study utilized advanced tracking technology, including Global Positioning Systems (GPS), to monitor patients undergoing spine surgery.
• Key metrics such as walking speed, daily activity, and time spent outdoors were recorded over several weeks.
• The technology aimed to provide objective, real-world data on patient function and recovery post-surgery.

Findings:

• In one patient, tracked parameters showed progressive improvement, correlating with successful surgical recovery.
• In the second patient, tracking revealed mobility issues, leading to the diagnosis of a separate orthopedic condition and further surgery.
• The technology effectively captured distinct recovery trajectories and identified unforeseen complications.

Implications:

• This spatial tracking technology offers a novel, objective method for assessing patient activity and recovery post-surgery.
• Data can enhance understanding of musculoskeletal limitations, perioperative function, and complication causes.
• Future applications may include developing valid outcome measures, refining patient selection for interventions, and exploring links between spatial data and psychosocial well-being.
