abstract

BACKGROUND
Treatment of glenohumeral osteoarthritis in young patients is challenging. Total shoulder arthroplasty reliably addresses pain and dysfunction but compromises glenoid bone stock. Various efforts have been made to avoid a prosthetic glenoid component or to prevent glenoid erosion after hemiarthroplasty. Capsular interposition, meniscal allograft, and more recently, GraftJacket (Wright Medical Technology Inc, Arlington, TN, USA), a human dermal collagen allograft, have been proposed for interposition arthroplasty in young patients with glenohumeral osteoarthritis.

METHODS
From 2009 to 2010, GraftJacket was used for glenoid resurfacing combined with humeral resurfacing or a stemmed hemiarthroplasty in 6 patients with a mean age of 47 years (34-57 years). Before GraftJacket was available, 5 patients were treated with a meniscal allograft and 6 with capsular interposition arthroplasty.

RESULTS
At a mean of 16 months (9-22 months) after the GraftJacket was implanted, 5 of the 6 patients were revised to a total shoulder arthroplasty or a reverse total shoulder arthroplasty. The sixth patient was dissatisfied but declined further surgery. The mean relative, preoperative Constant score decreased from 35% (range, 13%-61%) to 31% (range, 15%-43%) at revision or latest follow-up. Of the 5 patients with meniscal allograft, 3 underwent revision at a mean of 22 months (range, 12-40 months), and 4 of the 6 patients with capsular interposition were revised at a mean of 34 months (range, 23-45 months). The mean relative Constant scores preoperatively and at revision or latest follow-up were 44% (range, 19%-68%) and 58% (range, 9%-96%) for the meniscal allograft patients and 47% (range, 38%-62%) and 63% (range, 32%-92%) for the capsular interposition cases.

CONCLUSION
In our hands, 3 different types of biological resurfacings combined with humeral hemiarthroplasty have an unacceptable early failure rate.
