title: [Replacement of the Glenoid Using a Reconstruction Socket (EPOCA RECO].
abstract: OBJECTIVE
  Alleviation of pain, restoration of function and active range of motion in the shoulder in case of cuff tear arthropathy.
  
  
  METHODS
  Cuff tear arthropathy with an insufficient coracoacromial arch and salvage operation of failed hemiprosthesis or reverse shoulder prosthesis.
  
  
  METHODS
  Active or chronic infections. Lesions of the plexus. Insufficiency of deltoid muscle or subscapularis muscle. Neurologic diseases. Young active patients.
  
  
  METHODS
  Deltopectoral approach. Resection of the humeral head and removal of the failed implant, respectively. Periarticular arthrolysis with preservation of neurovascular structures. Exposure of the glenoid and three-point fixation of the reconstruction socket (EPOCA RECO) at the glenoid, the acromion and the coracoid process. Cemented fixation of the polyethylene inlay. Cemented or cementless implantation of the humeral stem in 25 degrees retroversion related to the long axis of the forearm. Reconstruction of the subscapularis muscle.
  
  
  METHODS
  Bedding of the arm in a Gilchrist brace. Passive and active- assisted exercises including continuous passive motion.
  
  
  RESULTS
  From 2002 to 2007, a total of 35 reconstruction sockets (EPOCA RECO) were implanted in 34 patients (six men, 28 women - one bilateral implantation was performed at an interval of 8 months in a female patient). Five EPOCA RECO implants had to be removed due to major complications. Three patients died, another three patients refused the follow-up examination. The remaining 23 patients (three men, 20 women, average age at the time of surgery 76 years [64-88 years]) were examined 2 years (4-60 months) postoperatively. The preoperative gender-related Constant Score was 21 and improved significantly (p < 0.001) to 58 postoperatively. The pain was significantly reduced. Range of motion for active elevation, internal and external rotation was improved (preoperatively/ postoperatively): elevation 37.2 degrees/65 degrees; internal rotation 14.8%/50%; external rotation 11.3%/47.5%. All patients would undergo the operation again. Overall, there were five major and two minor complications (complication rate 20%).
