Efficacy of Transosseous Tunnel Placement for Triple Endobutton Plate in Acromioclavicular Joint Reconstruction: A Three‐Dimensional Printing Guide Design Technology

Abstract

Objective: Explore an accurate transosseous tunnel drilling method based on three-dimensional (3D) printing technology for acromioclavicular joint reconstruction (ACD), design a guide design, and evaluate its accuracy.Methods: Using Mimics software to reconstruct 100 cases of acromioclavicular joint computed tomography (CT) data.In design 2, the non-collinear tunnel is superimposed on the 3D model, and a virtual drilling is performed between the clavicle and the coracoid using a triple inner gusset. Then, in the Geomagic Studio software model, an elliptical plane is calculated and extracted as a guide design for precise drilling. Then put the design and the 3D shoulder model together for 3D printing. Ten lengths were measured, and the effects of the virtual model, the actual model, and the guide rail design were compared. Results:We successfully compared 10 parameters of 3D virtual model and actual model. There was no significant difference between actual and virtual bone tunnels in 10 measurements (P > 0.05). Conclusions:The accuracy of ACD combined with 3D printing guidance design technology in the transosseous tunnel of adult shoulder is reliable.

Transcoracoid Drilling for Coracoclavicular Ligament Reconstructions in Patients With Acromioclavicular Joint Dislocations Result in Eccentric Tunnels

“…9 The results of this study seem to confirm the conclusions of Coale et al 9 Surgeons 18 Navigation did not require any readjustments, but drill misguidance and cortical breaches were observed in 2 cases (20%) with the standard technique. Custom-made drill guides using 3-dimensional (3D) printing have been developed by Zhang et al 19 Based on computed tomography images, 3D-printing software was used to create drill guides for transclavicularetranscoracoid tunnel drilling, and they have demonstrated an accuracy of 0.1 mm for 10 measured parameters when assessing tunnel placement in a virtual 3D shoulder model. 19 Central coracoid tunnel placement and projection seems critical to avoid complications.…”

Ferreira et al 20 have investigated tunnel trajectory and demonstrate that superior center-to-inferior center or superior medial-to-inferior central tunnel orientation reduces the risk of coracoid fracture.…”
