Niederfeld MR-Arthrographie der Schulter: Erste Ergebnisse mit einem offenen 0,2 T MR-System

1998

PURPOSE To assess the practicability and image quality of doing MR arthrography of the shoulder using a 0.2T system. PATIENTS AND METHOD 60 patients (24 with chronic instability, 36 with impingement syndrome) were examined in an open 0.2T MR apparatus (Magnetom Open, Siemens). After the intra-articular injections of 15-20 ml of a 2 mmol Gd-DTPA solution, coronary STIR, T1-weighted, sagittal and axial T2*-weighted FLASH 2D sequences were performed. 21 patients subsequently underwent surgery. RESULTS Image quality of the T1- and T2*-weighted FLASH 2D sequences was regarded as good or adequate and movement artifacts were minor or moderate. STIR sequences were statistically significantly worse …

Reliability of isokinetic assessment of shoulder-rotator strength: a systematic review of the effect of position.

2011

Context:Isokinetic assessment of shoulder internal- (IR) and external-rotator (ER) strength is commonly used with many different postures (sitting, standing, or supine) and shoulder positions (frontal or scapular plane with 45° or 90° of abduction).Objective:To conduct a systematic review to determine the influence of position on the intersession reliability of the assessment of IR and ER isokinetic strength, to identify the most reliable position, and to determine which isokinetic variable appears to be most stable in intersession reliability.Evidence Acquisition:A systematic literature search through MEDLINE and Pascal Biomed databases was performed in October 2009. Criteria for inclusion…

Internal Fixation of Proximal Humeral Fractures: Current Concepts

2003

Fractures of the proximal humerus are an increasingly common type of injury. Mainly elderly patients with osteoporotic bone are affected. Whereas non-displaced and stable fractures are managed successfully with conservative treatment, there is no general agreement on the surgical strategy for displaced and unstable two- to four-part fractures. The clinical outcome is influenced by the fracture type and concomitant injury to the rotator cuff. Extensive surgical manipulation of the soft tissues, non-anatomic and/or unstable fixation as well as technical errors are important contributing factors to poor clinical results. Goals of surgical treatment are to restore anatomy, to achieve fixation t…

Association Between COL5a1, COL11a1, and COL11a2 Gene Variations and Rotator Cuff Tendinopathy in Young Athletes

2021

Objective Tendinopathy is a prevalent condition in young athletes and in older nonathletic people. Recent tendinopathy research has shown a growing interest in the role played by genetic factors, basically genes involved in collagen synthesis and regulation, in view of collagen disorganization typically present in tendon pathologies. Design A case-control, genotype-phenotype association study. Setting La Ribera Hospital, Valencia, Spain. Participants A group of 137 young athletes (49 with rotator cuff tendon pathology and 88 healthy counterparts) who played upper-limb-loading sports were clinically and ultrasound (US) assessed for rotator cuff tendinopathy were included. Intervention Geneti…

Bedeutung der Kalkdepot-elimination bei Tendinosis calcarea der Schulter

2000

Aim: To evaluate the effect of complete elimination of the calcific deposit on the clinical outcome in patients with a recalcitrant calcifying tendinitis of the shoulder. Patients and methods: 50 patients with a chronic calcifying tendinitis of the shoulder (Type Gartner I or II) underwent a single application of extracorporeal shock waves (3000 impulses, energy flux density 0.60mj/ mm 2 ). After one year 45 patients were evaluated radiologically and clinically. Results: Radiologically a complete absorption of the calcific deposit was observed in 21 patients (47%). In 9 patients there was no radiological change. The radiological success was closely related to the radiomorphology of the depo…

Nonunion and malunion in proximal humerus fractures

2020

Proximal humerus fractures are common injuries and the development of nonunion or malunion is infrequent. However, these complications can occur with both operative and non-operative treatment of the fracture. A complete evaluation of these patients must include an investigation of the original fracture, bone and soft tissue quality as well as an extensive radiological study with X-Ray, CT and MRI. Asymptomatic and low demanding patients can benefit from conservative treatment, otherwise surgery is necessary. Multiple treatment options exist with no consensus upon the gold standard. The management of these complications is case-specific and needs extensive pre-operative planning. Arthroscop…

Frozen shoulder: a sympathetic dystrophy?

2000

Diagnostic and clinical features of the frozen shoulder syndrome and the Sudeck syndrome are similar in many aspects. Radioisotope bone scan shows an increased uptake in affected areas in both diseases, while native radiographs show a progressive demineralisation. Measurement of bone mineral density (BMD) by quantitative digital radiography objectified these local decalcification processes in an early stage of the frozen shoulder syndrome; 10 of 12 patients with primary frozen shoulder had BMD decreases greater 21% in the humeral head of the affected shoulder compared to the non-affected side. In the immobilised control group with degenerative changes of the rotator cuff, calcifying tendini…

The Shoulder Girdle

2000

The shoulder girdle is an anatomically complex structure consisting of the scapula, clavicula, proximal humerus, and their articular connections. The wide range of motion is provided by the glenohumeral joint and the two shoulder girdle joints, the acromioclavicular and sternoclavicular joints.

Influence of sutures configuration on the strength of tendon-patch joints for rotator cuff tears treatment

2019

Abstract Purpose Massive rotator cuff tears are common in the aging population. The incidence of failed rotator cuff repairs is still quite high, especially in the treatment of full-thickness tears or revision repairs. In this context, natural and synthetic meshes can be used as augmentation scaffolds or as devices to close the gap between a retracted tendon and the bone. The purpose of this work is to evaluate the ultimate tensile strength of different tendon-patch joints in order to consider their use in the treatment of massive cuff tears. Materials and methods Porcine tendons and a synthetic low-density polypropylene mesh have been used. A preliminary study on the tensile strength of te…
