Quantitative and Morphological Study of Glenoid Bone Defects in Athletes with Habitual Shoulder Dislocation: Comparison of CT Scan and 3D Printing
Summary:
The purpose of the present study was a) to develop a new methodology for calculating the glenoid bone loss in athletes with habitual dislocation of the shoulder using 3D printing and b) to investigated whether the quantitative assessment of the glenoid bone loss using 3D printing is an accurate assessment method compared to the methods in which CT tomography is used. Morphometric analysis and calculation of the glenoid bone loss was performed in 44 athletes, with an average age of 33.73±8.54. 25% of the sample were women and 75% were men, while the average number of dislocations was 3.25±1.98. In all cases, a three-dimensional printed model of the pathological glenoid was made as well as of the normal glenoid. In the digital models the glenoid bone loss was calculated using the below methods: a) PICO, b) the glenoid index, c) the anteroposterior glenoid distance and d) the relative height/width of the glenoid. The printed models were evaluated for: a) the glenoid index method, b) the anteroposterior glenoid distance method, and c) the relative glenoid height/width method. For the reliability of the method, the intraclass correlation index (ICC) was calculated. Perfect agreement was observed between the measurements of the same examiner with ICC values >0.989 for all methods, as well as between the measurements of two different examiners with ICC values >0.989 respectively. During the correlation between the techniques for calculating the glenoid bone loss in the 3D printed models and the PICO method, a moderate correlation was observed for the anteroposterior distance method and for the glenoid index method (ICC=0.69 and ICC=0.738 respectively), while good agreement was observed with the relative height/width method of the glenoid (ICC=0.856). The most common morphological shape of the glenoid was the pear form with rates of occurrence in the normal glenoid between the two methods 64.3% versus 71.4%% (printed versus digital models), while for the pathological glenoid 27.3% versus 31.8% respectively. The most frequent type of notch in the glenoid is the type with one notch at a rate of 88% among the normal ones, while in pathological cases a decrease in the appearance of the glenoid type with 1 incision was observed at 55% and an increase of the glenoid type without incision at a rate of 45% against 7% of normal glenoid. The calculation of the glenoid bone loss using 3D printing is a reliable method compared to the PICO method and is particularly useful in the simultaneous evaluation of the morphological characteristics of the glenoid (shape, type of notch, depth).
