Clinical Trial Summary

Reverse total shoulder arthroplasty has been widely used in the treatment of rotator cuff arthropathy. Follow-up has historically focused on the glenoid component because of problems with fixation and scapular notching leading to functional failure. Since several patients have shown cortical thinning of the proximal lateral humeral cortex during follow-up, further research is recommended to evaluate the cause and clinical impact of these radiographic changes. The goal of this study is to collect long-term radiographic and clinical data in order to facilitate the identification of risk factors.

Description:

Reverse total shoulder arthroplasty has been widely used in the treatment of rotator cuff arthropathy. Follow-up has historically focused on the glenoid component because of problems with fixation and scapular notching leading to functional failure. Fixation of the humeral component has evolved from cemented to mostly uncemented with diaphyseal of metaphyseal press-fit stems. Bony changes around the stem reflect the bone-implant interface; research to evaluate and interpret these changes is insufficient at this moment. Since several patients have shown cortical thinning of the proximal lateral humeral cortex during follow-up, further research is recommended to evaluate the cause and clinical impact of these radiographic changes. The goal of this study is to collect long-term radiographic and clinical data in order to facilitate the identification of risk factors.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Shoulder X-ray	To describe bony reaction at the bone-implant interface for the humeral component of a reverse shoulder arthroplasty. End-point radiographs will be compared to radiographs taken postoperatively in order to define stress shielding and/or bone resorption in the 5 humeral zones described by Nagels et al.	up to 20 months
Secondary	Clinical outcome	To relate bony changes at the bone-implant interface of the humeral component of a reverse total shoulder arthroplasty to clinical outcome	up to 20 months
Secondary	Constant-Murley score	To evaluate the functional state of the shoulder in patients with shoulder complaints	up to 20 months
Secondary	Short Form 36 Health Survey Questionnaire (SF-36)	To indicate the health status and pain scales	up to 20 months
Secondary	Net Promotor Score (NPS)	To evaluate patient satisfaction after surgery	one time visit
Secondary	Anchor Question Shoulder Score	To measure the change in general daily functioning and pain symptoms after shoulder surgery	up to 20 months
