Anatomic stemless shoulder arthroplasty and related outcomes: a systematic review
Background: The latest generation of shoulder arthroplasty includes canal-sparing respectively stemless designs that have been developed to allow restoration of the glenohumeral center of rotation independently from the shaft, and to avoid stem-related complications. The stemless prosthesis design has also recently been introduced for use in reverse arthroplasty systems. Methods: We systematically reviewed the literature for studies of currently available canal-sparing respectively stemless shoulder arthroplasty systems. From the identified series, we recorded the indications, outcome measures, and humeral-sided complications. Results: We identified 11 studies of canal-sparing respectively stemless anatomic shoulder arthroplasty implants, published between 2010 and 2016. These studies included 929 cases, and had a mean follow-up of 26 months (range, 6 to 72 months). The rates of humeral component-related complications ranged between 0 and 7.9 %. The studies reported only a few isolated cases of complications of the humeral component. Some arthroplasty systems are associated with radiological changes, but without any clinical relevance. Conclusions: All of the published studies of canal-sparing respectively stemless shoulder arthroplasty reported promising clinical and radiological outcomes in short to midterm follow-up. Long-term studies are needed to demonstrate the long-term value of these kind of implants
Single versus double row suture anchor fixation for greater tuberosity fractures: a biomechanical study
Incidence of os acromiale in patients with rotator cuff tear and a normal population without shoulder diseases.
Ein Os akromiale ist das seltene Ergebnis einer fehlerhaften bzw. ausgebliebenen Verschmelzung der Epiphyse des anterioren Anteils des Akromions. Die Häufigkeit eines Os akromiale in der Literatur reichen von 1,3 -15%. Das Ziel der Arbeit war letztlich zu zeigen, inwiefern ein Os akromiale als Kofaktor einer Rotatorenmanschettenruptur angesehen werden kann. Dafür untersuchten wir die Rötgenaufnahmen von 1000 Patienten mit Ruptur der Rotatorenmanschette auf das Vorhandensein eines Os akromiale. Außerdem wurden 1000 Schultern eines Normalkollektivs ohne Schultererkrankung (mittels Ultraschall) ebenfalls auf das Vorhandensein eines Os akromiale untersucht. Es zeigte sich, dass ein Os akromiale bei Patienten mit Ruptur der Rotatorenmanschette mit einer Inzidenz von 6,2 %, bei asymptomatischen Probanden mit einer Häufigkeit von 3,3 % auftritt. Folglich kann das Os akromiale als Kofaktor bei der Entstehung einer Rotatorenmanschettenruptur angesehen werden.An os acromiale is a rare anatomical condition and the result of a failed fusion of the anterior part of the acrmion. The incidence in literature ranges from 1,3 to 15 %. The purpose of this study was to investigate, whether an os acromiale can be judged as a co-condition in rotator cuff tears. Therefore we assessed the radiographs for the presence of os acromiale in 1000 patients with tear of the rotator cuff. Furthermore we assessed 1000 shoulders of a normal population without shoulder disease (via ultrasound) for the presence of an os acromiale. We found, that in patients with tear of the rotator cuff the incidence of an os acromiale was 6,2% compared to 3,3% in the population without shoulder diseases. Consequently an os acromiale must be judged as a co-condition in rotator cuff tears
