When rotator cuff deficiency is present with gleno-humeral osteoarthritis, the current treatment is a reverse total shoulder arthroplasty. The reverse shoulder prosthesis has inverted articular surfaces: a metallic ball (glenosphere) is fixed on the scapul ...
Background: Local bisphosphonate delivery may be a solution to prevent periprosthetic bone loss and improve orthopedic implants fixation. In load-bearing implants, periprosthetic bone is exposed to high mechanical demands, which in normal conditions induce ...
Reversed shoulder prostheses are used for the treatment for glenohumeral arthritis associated to rotator cuff muscle deficiency. The glenoid component is fixed with peripheral screws, which provide the primary stability that is crucial for the long-term os ...

Reverse shoulder arthroplasty has become the classical treatment for glenohumeral joint arthritis associated with rotator cuff dysfunction. The design of the prosthesis, the fixation of the implant and the surgical technique are however still to be improve ...
Background: The primary stability of cancellous screw is difficult to obtain in bone of compromised quality and failure of screw fixation is common. To overcome this problem, it is proposed to locally deliver bisphosphonate from the screw An in vivo valida ...
We have recently demonstrated that indentation-type atomic force microscopy (IT-AFM) is capable of detecting early onset osteoarthritis (OA) (Stolz, 2009). This study was based on biopsies, using a desk-top commercial atomic force microscope (AFM). However ...

The primary stability of cementless femoral components is crucial for the long-term success of total hip arthroplasty. We know that the healing phase after surgery is a complex biological process, which is affected by the mechanical environment. Implant lo ...
In this work a 3D musculoskeletal model of the knee joint, that can simulate a squat movement, has been developed. Such a model would be useful to understand the biomechanics of the knee. The model consisted of all the the bones with their articular surfac ...
Variable definitions of outcome (Constant score, Simple Shoulder Test [SST]) have been used to assess outcome after shoulder treatment, although none has been accepted as the universal standard. Physicians lack an objective method to reliably assess the ac ...
