“…Early promising results have been reported in cadaveric and clinical studies. 12,28,51,53 Whereas the technology can improve both humeral and glenoid implant alignment in routine cases, it is especially useful in situations in which normal anatomy is distorted, such as with fractures, glenoid erosion, dysplasia, and revisions. Taken yet a step further, patient-specific instrumentation is now available for shoulder arthroplasty.…”

“…No prospective clinical study has so far been reported on the use of CT navigation in RSA but the technique on cadavers has yielded satisfactory results. Verborgt and colleagues11 in a cadaveric study comparing CT navigation and conventional technique concluded that CT navigation significantly improves glenoid component positioning in reverse shoulder arthroplasty. Of the 14 cases in each group, there was perforation of the superior screw in four patients and the inferior screw in one patient.…”

CT navigation has been shown to improve component positioning in total shoulder arthroplasty. The technique can be useful in achieving strong initial fixation of the metal backed glenoid in reverse shoulder arthroplasty. We report a 61 years male patient who underwent reverse shoulder arthroplasty for rotator cuff arthropathy. CT navigation was used intraoperatively to identify best possible glenoid bone and to maximize the depth of the fixation screws that anchor the metaglene portion of the metal backed glenoid component. Satisfactory positioning of screws and component was achieved without any perforation or iatrogenic fracture in the scapula. CT navigation can help in maximizing the purchase of the fixation screws that dictate the initial stability of the glenoid component in reverse shoulder arthroplasty. The technique can be extended to improve glenoid component position [version and tilt] with the availability of appropriate software.

“…Five works have been Verborgt et al [30] showed a higher accuracy for achieving a central position of the glenoid in the axial plane and a 10°t ilt in the frontal plane by using a navigation system in a cadaver study. Similar improvements by employing computer navigation for better accuracy of reaming of the glenoid and glenoid component positioning showed three other cadaver studies [5,20,21].…”

The treatment of three- and four-part fractures of the humeral head is still controversially discussed. Some advocate primary arthroplasty while the results of primary fixation seem to be superior if no necrosis of the humeral head develops. Today navigation is used in orthopaedic surgery mainly for interventions on the spine, the pelvis and arthroplasty. In trauma surgery it is still rarely used and some technical problems need to be overcome. We report on a case of a three part fracture of the humeral head with mini-open reduction and fixation with image-based guided headless compression screws. For the fixation each screw was placed on the first trial, total radiation time was 60 s. At 12-month follow-up assessment radiographs showed a consolidated fracture, no loosening of the screws and a good glenohumeral articulation. The patient had free function of the shoulder and no pain, the constant score was 98 and the dash score 0. There is no evidence of a necrosis of the humeral head. The literature focuses on shoulder arthroplasty. There are no reports on the use of image-based guidance in shoulder traumatology so far. In conclusion, the described technique allows an accurate fixation of the humeral head fracture as the guidance system (Surgix) ensures the "first try first hit" screw positioning. The new system was integrated in the workflow and supports the surgeon as an aiming device. The role of navigation system in enhancing minimally invasive surgery of the shoulder should be further explored.
