Objective:
Evaluation of the functional results of the Delta 3 inverted shoulder prosthesis and determination of a radio-anatomical index predictive of best functional outcome.
Patients And Methods:
Retrospective analysis of 19 patients (21 shoulders). Clinical (pain, satisfaction, amplitudes, Constant index) and radiological (acromio-epiphyseal distance) evaluation at a mean follow up of 13.6 months.
Results:
Outcomes concerning pain, quality of life and Constant index were good and similar to other series. Few complications were observed. An increase of the acromio-epiphyseal distance of 33 to 50% compared to the non operated side is associated with a good functional result.
Conclusion:
Our results confirm those of other series and show that Delta 3 inverted prosthesis is an efficient therapeutic alternative in arthropathy with rotator cuff tears. Rehabilitation is fairly short and easy. The increase of the acromio-epiphyseal distance determines the tension of the deltoid muscle and could predict a favorable outcome.
