Background

The aim of this study is to document a single surgeon's experience performing revision reverse shoulder arthroplasty after baseplate failure.

Methods

Revision reverse shoulder arthroplasty (RSA) for mechanical failure of the glenoid baseplate after RSA was performed in 14 patients. Clinical and radiographic data were collected preoperatively, prior to baseplate failure, after baseplate failure, and at latest follow-up after revision (average, 33 months).

Results

When comparing the pre-operative values to post-revision, ASES, forward elevation, and abduction were significantly improved. There was no significant difference in any of the outcome measures when comparing the prefailure data to the post-revision data. The post-revision prosthesis-scapular neck angle (PSNA) showed a significant increase in inferior tilt of the baseplate when compared to pre-failure PSNA (P < .001). Two patients (14%) required a second revision RSA for glenoid baseplate failure (1) and dislocation (1); 1 additional patient developed a postoperative hematoma which resolved without surgery.

Conclusion

Revision RSA for the treatment of glenoid baseplate mechanical failure can restore pain relief and function to the levels gained after the index RSA.

Level of evidence

Level IV, Case Series, Treatment Study.
