Years after a total shoulder arthroplasty on the left scapula, a 64-year-old male still had severe complaints. He suffered from a type 2 central defect with abnormal ossification surrounding the glenoid. Prof. Stefaan Nijs, Chairman of Trauma Surgery at Leuven University Hospital in Belgium took on the case and headed the revision surgery. Seeing the complexity and unusual size of the defect in the patient’s shoulder, Dr. Nijs chose to work with Materialise’s experts and the Glenius implant. He performed a two-stage procedure. Stage one entailed the removal of the previous implant and inserting a spacer. In the second stage, the Glenius was implanted.
3D-printed components for complex post-op defect
The two-part surgery went smoothly and as planned. There were no incidents during the removal of the components. Removing the spacer, cleaning of the area, and tissue sampling for possible infection took roughly one hour, after which the surgical team was ready to place the implant. The insertion went very well, due to the welcoming size of the incision and the small size of the prosthesis. The patient-specific guides provided with the surgery helped to find the unique position. Prof. Nijs first double-checked by testing the implant on the bone model. He then fitted the implant in its real position rather quickly, despite the smoothness of the defect surface. Finally, he proceeded with the drilling, using the 3D-printed guide. The depth of the screw holes was verified before he inserted the screws. The first four screws fit as planned, but the fifth was more challenging due to no solid grip in the second cortex. However, as the length prediction of the previous screws was correct, Dr. Nijs continued with the planned screw length for screw 5.
