Research summary
Summary of Research
The Upper Limb Unit at Wrightington Hospital has been using the Lima Axioma TT implant since 2013 as a routine surgical choice for patients who require total shoulder replacement and more recently as an integral part of several research studies. This retrospective study would enable us to clinically assess and to obtain function measurements from patients at a minimum of two years after surgery. A CT scan would give further information regarding implant integration.
Summary of Results
Shoulder arthritis affects around 1 in 4 people in the UK, it is more common in women and risk increases with age. Arthritis causes pain and can limit arm movements.
Shoulder replacement surgery is widely available to treat these symptoms and many patients get good results from surgery. The operation involves replacing damaged bone with new plastic or metal parts. In some people the socket of the joint (called the GLENOID), becomes badly worn and a simple implant is not enough to fill the gap in the bone. In these cases, as disc of bone can be attached to the new implant which then heals with the good bone when the arthritis worn bone is removed. This disc of bone is called a GRAFT and can be made from the persons own bone (an AUTOgraft) or donated bone (an ALLOgraft). In complicated cases, a special implant is designed using special CAT scan (computed x-ray) images. The implants are made using these scans and '3D' printed using special machines so they will fit perfectly into the gap in the bone.
We reviewed 109 patients with bone graft or 3D printed implants. Patients seen at 2 years with new x-rays and CAT scans were asked questions about their shoulder pain and function.
Most patients had good outcomes and images showed good healing of the autografts. 3D printed implants were successful and are very useful in complex cases.REC name
