Brief Summary:
The clinical question on whether or not to replace the glenoid component in patients with a degenerative shoulder disease, has not been answered yet in a randomized study with enough statistical power. In this study, patients are randomly allocated to a treatment with a hemi- or total shoulder arthroplasty using implants of the Epoca system. The primary objective is the comparison of pain and function between the treatment groups after 5 years using the Constant score.
Detailed Description:
Shoulder arthroplasty is accepted as the treatment of choice for improved function with minimum pain in well-selected patients. A persistent discussion remains as to whether replacement of the glenoid (ie, total arthroplasty) should be performed. Possible advantages of glenoid replacement include decreased pain compared to hemiarthroplasty with a metal-on-bone articulation, increased stability due to the conforming glenoid component, and lateralization of the joint center providing improved range of motion and abduction strength. Potential complications of glenoid replacement are implant loosening and loss of glenoid bone stock.
If a hemiarthroplasty is performed, glenoid replacement and related complications are avoided. In addition, hemiarthroplasty requires less surgical time and is less expensive than total shoulder arthroplasty.
To date, there is no evidence to answer the clinical question on whether or not to replace the glenoid component in patients with a degenerative shoulder disease. In this study, both the stemmed Epoca humeral component (Epoca Stem) and the Epoca Resurfacing Head (Epoca RH) are included. While the stemmed prosthesis was developed both for nonreconstructable fractures and omarthroses, the humeral resurfacing head implant was designed specifically for use in degenerative diseases of the shoulder joint.
This randomized multicenter study aims to compare the efficacy of hemi versus total shoulder arthroplasty using Epoca RH or Epoca Stem in patients with degenerative joint diseases. The primary aim of the present study is to demonstrate that the Constant score assessing shoulder function and pain is higher in the patient group treated with total arthroplasty compared to the hemiarthroplasty group after 5 years. The secondary aims of the study are to assess differences in the Shoulder Pain and Disability Index (SPADI), duration of surgery, rates of local and general adverse events and relationship to the device or treatment under investigation, survivorship of the implants, and quality of life after 6 months, 1, 3 and 5 years between the treatment groups.
