Is shoulder arthroplasty an option for charcot arthropathy?

Introduction
Charcot arthropathy is a rare cause of debilitating joint destruction. Shoulder arthroplasty for Charcot arthropathy is challenging secondary to local bone and soft tissue loss, lack of protective sensation, and altered muscle control. The purpose of this study is to review the outcomes, complications, and survivorship of shoulder arthroplasty for Charcot arthropathy.
Methods
Between January 2000 and December 2011, ten shoulders with Charcot arthropathy were treated with shoulder arthroplasty at our Institution (six hemiarthroplasty, one total shoulder arthroplasty, three reverse shoulder arthroplasty). Shoulders were followed for a minimum of two years or until re-operation. Outcomes measures included pain, range of motion, complications, and reoperation.
Results
Shoulder arthroplasty improved pain to a mean score of 2.6 at follow up. However, gains in range of motion were not as substantial, with mean elevation of only 105°. External rotation improved from 20 to 43°. Subjectively, six of the ten patients rated the result as much better or better. Two shoulders underwent revision surgery at an average of five months after index arthroplasty.
Conclusion
Shoulder arthroplasty for the treatment of the sequelae of a Charcot joint is a reasonable treatment option to provide substantial pain relief and improved motion. The relative indications of hemiarthroplasty, total shoulder arthroplasty, and reverse shoulder arthroplasty for this particular condition continue to evolve.
