So werden in Deutschland inzwischen jedes Jahr rund 25. The anterior deltoid is divided from the anterior edge of the acromioclavicular arch, allowing exposure to the glenoid for glenosphere implantation. It is helpful for orthopaedic surgeons to understand ways to avoid these complications and methods with which to treat them. External and internal rotation tasks could be performed by only 13 patients 14 shoulders; nine primary, five revisions generating 9 Nm ± 4 Nm and 8 Nm ± 3 Nm, respectively 13%-71% of normal shoulders. Complications consisted of one patient with a chronically dislocating prosthesis, one patient with a deep wound infection, and one with a postoperative wound dehiscence. The combination of an irreparable tear of the rotator cuff and destructive arthritis of the shoulder joint may cause severe pain, disability and loss of independence in the aged.

Welche Art der Verankerung bei einer Schulterendoprothese zum Einsatz kommt, hängt von verschiedenen Faktoren ab. Bei der zementierten Variante besteht sofort nach der Implantation eine feste Verbindung zwischen der Schulterendoprothese und dem natürlichen Knochen, was eine frühzeitigere Belastung des operierten Schultergelenks unter krankengymnastischer Anleitung ermöglicht. Diese kann entweder ambulant von zu Hause aus oder stationär in einer Reha-Klinik, beispielsweise einem Schulterkompetenzzentrum, durchgeführt werden. At an average follow up of 77 months range, 14-180 months , 15 revisions 16. The appliance of anatomical hemiarthroplasty, on the other hand, has lost in significance in favour of osteosynthesis and reverse shoulder arthroplasty.

Die Kappenprothese ist die kleinste und einfachste Variante einer Oberarmkopfprothese. At the final follow-up, the mean Constant score improved significantly from 32. In a comparison of the deltopectoral and anterosuperior approaches in 527 reverse arthroplasties with a minimum 2-year followup, postoperative instability rate was greater with the deltopectoral 5. However, the number of nerve palsies increased. Upper extremity fractures in the elderly are very frequent and second only to hip fractures in the group of fragility fractures.

The formal evidence level regarding the best treatment strategy is low, and it has not yet been determined whether surgical or conservative treatment is better. This is a retrospective study of a continuous series of 85 reverse shoulder arthroplasties; 62 of these fulfilled inclusion criteria. Its main apparent advantages are simplicity, ease of axial humerus preparation, quality of frontal exposure of the glenoid, and due to subscapularis tendon preservation, a low risk of postoperative instability. The indications for reverse shoulder arthroplasty have continued to expand since it was first performed in the United States in 2004. These X-ray scans were classified twice by two orthopaedic surgeons with respect to infraglenoidal scapular notching according to the classification of Nerot.

A cylinder of autologous cancellous bone graft, harvested from the humeral head, was placed between the reamed glenoid surface and baseplate. Failure to restore sufficient tension in the deltoid may result in prosthetic instability. Inverse Schulterprothesen sind in den letzten Jahren zu einem Standardeingriff geworden. The management of patients with signs and symptoms referable to the rotator cuff depends on the presence of cuff injury and the size of the tear. Bei der Oberarmkopfkompmente handelt es sich entweder lediglich um eine Metallkappe, die als Oberflächenersatz auf den natürlichen Oberarmkopf aufgesetzt Kappenprothese bzw.

Mean active elevation increased from 74 degrees preoperatively to 149 degrees postoperatively +75 degrees , and external rotation increased from -21 degrees to 13 degrees +34 degrees. Without diagnosis and management, advanced cuff tears may progress to cuff tear arthropathy, a degenerative arthritis condition of the shoulder. So werden in Deutschland jedes Jahr rund 25. In 96% of these shoulders there was no or only minimal pain. Das heißt, am Oberarmkopf, der in der normalen Anatomie den konvexen Gelenkpartner darstellt, wird eine künstliche konkave Gelenkpfanne implantiert, während an der Schulterpfanne ein dem Oberarmkopf ähnlicher, kugeliger metallischer Kopf befestigt wird. We retrospectively reviewed 527 reverse shoulder arthroplasties performed in 506 patients between 1985 and 2003.
