Outcome measures
Primary outcome
Relation in postoperative change in deltoid volume and Constant Murley score
Secondary outcome
Oxford Shoulder score, range of motion (abduction, anteflexion, glenohumeral
abduction, external rotation, internal rotation, abduction+external rotation),
relation in postoperative change in deltoid volume and change in distalisation
of the humeral head.
Background summary
Remain of a proper function and strength of the deltoid muscle is an important
theoretical factor in long term results after reversed shoulder arthroplasty.
Because of the changed - non-anatomical - biomechanical situation following
reversed arthroplasty, there are doubts about the resistency of the deltoid
muscle against this changed situation. We hypothesize that a postoperative
decrease in volume of the deltoid muscle has a negative effect on clinical
outcome scores.
Study objective
Determing the relation between postoperative deltoid volume and clinical
outcome following reversed shoulder arthroplasty after 2-13 years of followup.
Study design
The study design is observational.
Study burden and risks
There is no different treatment. In addition to standard care there will be one
extra outpatient clinic meeting where we measure Range of Motion and deltoid
strength and complete two short questionnaires on the function of the operated
shoulder. Those questionnairs are completed pre-operatively as part of standard
care.
Further we will perform ultrasound measurement of the deltoid muscle on the
operated and healthy shoulder.
