Use of axial3D model to aid in the diagnosis and preoperative planning of complex rotator cuff arthropathy.
An elderly female patient was admitted to the Ulster Hospital with extensive pain and restricted movement in her right shoulder. The patient had previously undergone bone resurfacing of the humeral head and erosion of the glenoid cavity had started as a result of surrounding muscular anatomy failing. Both the metallic artifact and complex anatomical arrangement made traditional image interpretation difficult.
The surgeon was provided with a 1:1 scale 3D printed model of the shoulder girdle including the metallic shoulder resurfacing component encompassing proximal aspects of humerus and superior portion of the scapula (Fig 1, 2 & 3).
I was provided with a 3D model of a complex shoulder pathology which allowed me to see exactly where the glenoid had worn over time due to the resurfaced humerus and where the new articulating surface had formed superiorly to this. The model allowed me to plan with a much greater level of accuracy and the extra information ensured we avoided any surprises during surgery.
Mr. Jim McConway, Consultant Orthopedic Surgeon Ulster hospital, Northern Ireland
Access to the models gave a much greater understanding of the complexity of the articulating surfaces of the shoulder and allowed accurate planning for the joint resurfacing (Fig 4 & 5). The model was also used to determine that a new articulating surface had formed on the patient’s acromion process.
Using 3D printed models, trial operations can be carried out and used intraoperatively as guides to improve planning and reduce surgical time associated with difficult cases. Models improve communication with patients and clinicians. Articular lesions and deformities are particularly clear on the models compared to standard 2D scan images.
