“…The use of specialized views in the surgical evaluation of TMC osteoarthritis argues that this type of standardization of radiographs is possible, and this has been demonstrated in other joints as well. 35 Finally, the method was developed and validated using cadaveric specimens. Further validation utilizing in-vivo imaging from a larger sample size can strengthen the standardization and improve the accuracy and applicability of the developed radiographic TMC JSW measurement method.…”

Joint space width (JSW) is a common metric used to evaluate joint structure on plain radiographs. For the hand, quantitative techniques are available for evaluation of the JSW of finger joints; however, such techniques have been difficult to establish for the trapeziometacarpal (TMC) joint. This study aimed to develop a validated method for measuring the radiographic joint space of the healthy TMC joint.Approach: Computed tomographic scans were taken of 15 cadaveric hands. The location of a JSW analysis region on the articular surface of the first metacarpal was established in 3D space and standardized in a 2D projection. The standardized region was applied to simulated radiographic images. A correction factor was defined as the ratio of the CT-based and radiograph-based joint space measurements. Leave-one-out validation was used to correct the radiograph-based measurements. A t-test was used to evaluate the difference between CT-based and corrected radiograph-based measurements (α ¼ 0.05). Results:The CT-based and radiograph-based measurements of JSW were 3.61 AE 0.72 mm and 2.18 AE 0.40 mm, respectively. The correction factor for radiograph-based joint space was 1.69 AE 0.41. Before correction, the difference between the CT-based and radiograph-based joint space was 1.43 mm [95% CI: 0.99 − 1.86 mm; p < 0.001]. After correction, the difference was −0.11 mm [95% CI: −0.63 − 0.41 mm; p ¼ 0.669].Conclusions: Corrected measurements of radiographic TMC JSW agreed well with CT-measured JSW. With in-vivo validation, the developed methodology has potential for automated and accurate radiographic measurement of TMC JSW.
