Abstract
BACKGROUND

Patients with a shoulder arthrodesis generally experience restriction in range of motion and limitations in activities of daily living. In addition, up to one-third of the patients deals with serious peri scapular pain. The conversion of a shoulder arthrodesis in a reverse shoulder arthroplasty (RSA) has been described as an effective treatment to achieve better function and decreased pain, although literature is sparse. We present the case of a conversion from a painful shoulder arthrodesis to RSA, after a 51 years interval.

CASE SUMMARY

A 71-year-old male presented with severe peri scapular pain and limited function 51 years after shoulder arthrodesis. Preoperative workup showed a normal bone stock of the glenoid and an intact axillary nerve, but atrophic posterior part of the deltoid muscle. The shoulder arthrodesis was successfully converted to RSA. Twelve months postoperative the patient was very satisfied. He has no pain at rest, nor with exercise and experienced definite improvements in activities of daily living, despite his limited range of motion.

CONCLUSION

Conversion from shoulder arthrodesis to a RSA can be performed safely, with a high chance of peri scapular pain relief; even after a longstanding arthrodesis.

Core Tip: To the best of our knowledge, this unique presentation of a conversion from shoulder arthrodesis to reverse shoulder arthroplasty is the sixth reported case. This treatment should be considered in patients with a painful shoulder arthrodesis. Requirements for a successful procedure are adequate bone stock and a functional deltoid muscle. The treatment can be performed safely, with a high chance of peri scapular pain relief; even after a longstanding arthrodesis. Improvements of activities of daily living are noticed, with varying results of shoulder function.
