The retrospective analysis of 97 shoulder arthroplasties during 1998 to 2009 was performed. The hemiarthroplasty were fulfilled in 92 patients and total shoulder replacement in 5 patients. Total rate good and satisfactory results consists 32,0%, poor results - 68,0% (66 patients, include 5 patients with total shoulder arthroplasty). The lower level of good results was revealed in patients with chronic fractures and fracture-dislocations of shoulder. It related with changes bones of shoulder and muscles of shoulder (rotator cuff). In the studied group of patients there was no proper pre-operative diagnostics of the rotator cuff, articular surface of the scapula, which shows the need for careful preoperative examination to determine the indications for shoulder arthroplasty and select the type of prosthesis. Unsatisfactory results of total arthroplasty related to screw migration (in case of the transacromion approach) and to the development of subacromial impingement. The conclusion about the need to narrow the indications for use of the scapular component «Ortho-P». The authors showed preference to cemented implants without a metal base. It is necessary to introduce in practice the anatomic implants of the third generation allowing the fullest play the anatomy and biomechanics of the shoulder joint.

Purpose— to evaluate mid-term outcomes of reverse joint replacement in patients with shoulder arthropathy and massive rotator cuff tear.Material and Methods. Reverse shoulder arthroplasty with delTa xTeNd (depuy) was performed in 38 patients in the period from december 2010 to december 2016 by the same surgical team. patients’ age ranged from 38 to 82 years. Indications for replacement were pain syndrome and pseudoparalysis of the upper limb in presence of a large or massive Rc tear as well as shoulder arthropathy of various severity degree. Outcomes were evaluated by standard aSeS, cS and ucla scales. Roentgenological examination included ap and axial x-rays during follow up from 1 to 6 years after the surgery with analysis of implants positioning. Mean follow up was 24,2±6,6 months.Results. good outcomes were reported in 6 (15,8%) patients. average functional scores were: aSeS 87,4±2,1, ucla 29,7±1,5 and cS 14,0±2,3. Satisfactory outcomes were observed in 27 (14,2%) patients: aSeS 76,2±2,3, ucla 26,8±1,3 and cS 22,0±1,4 scores. poor outcomes were reported in 5 (14,2%) patients with persisting pain syndrome.Conclusion.To avoid significant and multiple complications after reverse shoulder replacement a precise preoperative planning considering particular destructive changes of glenoid fossa is required. For young and physically active patients the authors recommend to use alternative treatment options aiming at restoration of normal shoulder biomechanics and prophylaxis of arthropathy.
