Patient-specific Instrumentation versus Standard Surgical Instruments in Primary Reverse Total Shoulder Arthroplasty: A Retrospective Clinical Comparative Study
Description
The presented talk is given by Ahmed Elsheikh, a lecturer in trauma orthopedics from Benha, Egypt. He discusses his research on the clinical outcomes of patient-specific instrumentation (PSI) compared to standard reverse primary total shoulder arthroplasty, highlighting the background of his research undertaken during his fellowship in Liverpool.
Throughout the presentation, Ahmed discusses the existing literature regarding PSI, noting that it has been studied for nearly a decade, primarily focused on radiological precision. He shares contradictory results from systematic reviews regarding the accuracy of PSI, mentioning that while some studies have shown improved accuracy with PSI, others report no significant differences when compared to standard procedures.
A retrospective review of prospectively collected data from 137 patients was mentioned, ultimately resulting in the analysis of 53 patients who underwent primary reverse shoulder arthroplasty. Of those, 35 patients had standard procedures while 18 had PSI. The demographic data indicates a mix of genders with varied pathological backgrounds, primarily osteoarthritis mixed with rotator cuff insufficiency.
The methodology of the research measured various clinical outcomes, such as pain levels, functional scores, and range of motion, alongside radiological assessments, though limitations existed in preoperative imaging, particularly for the standard group.
The comparative outcomes suggested that both groups experienced comparable improvements postoperatively, though there was no significant difference in clinical outcomes between PSI and standard techniques, despite the PSI group showing favorable positioning of implants via imaging assessments. Noteworthy results included patient satisfaction scoring 10 out of 10 across both groups. Additionally, complications were minimal, with only a few patients requiring surgical intervention, all resulting in good outcomes.
Ahmed concluded that while both techniques achieved similar outcomes, PSI had effectively high positioning success rates without extending waiting or surgical times, calling for more robust comparative studies in the future to address some of the inherent limitations of his research.
