The customised glenoid prosthesis is a shoulder joint replacement that addresses glenoid osteoarthritis with severe glenoid bone loss.

^_Indications

degenerative bone diseases of the glenohumeral joint

chronic dislocations

outcomes of autoimmune diseases such as rheumatoid arthritis

sequelae of proximal humeral fractures treated with osteosynthesis with damaging of the glenoid articular surface due to extrusion or migration of fixation devices

prosthetic complications such septic or aseptic loosening of the glenoid component in anatomical or reverse shoulder arthroplasty with important loss of the glenoid bone stock

^{_{Radiographic features}}

^{_Preoperative}

Preoperative CT scans are analysed and reconstructed by computerised systems to determine the area and shape of the glenoid component fixation element of the implant.

^{_{Postoperative}}

Shoulder x-rays with anteroposterior and lateral views can be utilised as the initial study for postoperative review.

Signs of implant loosening:

radiolucent lines
scapular notching
prosthesis dislocation
