The customised glenoid prosthesis is a shoulder joint replacement that addresses glenoid osteoarthritis with severe glenoid bone loss.
Indications
Indications for custom-reverse implants are related to patient functional demand and remaining bone stock, not recommended in patients with reduced functional demand, and include:
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
