Learning objectives - To present the BCT-view method as a refined, advanced technique for carpal tunnel imaging.- To address critical limitations in conventional methods (Gaynor-Hart and Marshall), particularly regarding reproducibility, radiation exposure, and patient positioning.- To establish the BCT-view method as a gold standard through rigorous quantitative and qualitative assessments.
Read more Background Carpal Tunnel Syndrome (CTS), the most common entrapment neuropathy, involves median nerve compression in the carpal tunnel. Cost-effective X-ray imaging aids in excluding degenerative changes, fractures, or trauma-related abnormalities, ensuring precise CTS diagnosis by ruling out alternative causes. Traditional imaging techniques, including the Gaynor-Hart and Marshall methods, present challenges such as inconsistent reproducibility, patient discomfort, and unnecessary radiation exposure. This study introduces the BCT-view method—a rigorously validated protocol designed to optimize diagnostic precision while minimizing patient burden.
Read more Findings and procedure details 1.Reproducibility Evaluation 1) Lunate-Capitate Overlap: BCT-view achieved superior reproducibility (SD = 0.10) compared to Gaynor-Hart (SD = 0.46) and Marshall (SD = 0.20). 2) Scaphoid-Trapezium Isolation: BCT-view demonstrated significant improvement (SD = 0.16) versus Gaynor-Hart (SD = 0.60) and Marshall (SD = 0.53). 3) Carpal Tunnel Size: BCT-view showed the lowest variation (SD = 0.15) compared to Gaynor-Hart (SD = 0.60) and Marshall (SD = 0.60).2. Radiation Dose Evaluation 1) Eye Dose: BCT-view reduced radiation exposure to the eye by 63% compared to Gaynor-Hart...
Read more Conclusion The BCT-view method outperforms traditional imaging techniques with a 60% reduction in total radiation dose compared to the Gaynor-Hart method and a 7% reduction compared to the Marshall method. Furthermore, reproducibility was significantly enhanced, with a 78% improvement in lunate-capitate overlap consistency compared to Gaynor-Hart and a 50% improvement compared to Marshall. Additionally, carpal tunnel size reproducibility improved by 75% compared to both Gaynor-Hart and Marshall methods. Patient ergonomics also showed marked advancements, with convenience and stability scores of 4.8/5...
