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…
Orthotope arterialisierte Lebertransplantation bei Ratten mit Stenttechnik der supra- und infrahepatischen v. cava
2003
The aim of this study was to establish a liver transplant model with a reduced warm ischemic period between cold preservation and completed anastomosis. Male brown Norway rats were used. A cuff was fixed in the portal vein, stents were inserted in the A. hepatica, the suprahepatic and infrahepatic v. cava and in the bile duct. After cross clamping of the recipient liver, another stent, occluded by a small pin, was introduced in the recipient suprahepatic v. cava. After ligation of this recipient suprahepatic caval stent the recipient liver was removed and the cold prepared donor liver was pushed forward along the pin and both suprahepatic stents of recipient and donor were connected. Then c…
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…
Subglottic stenosis imitating the carina – a case report of airway mimicry
2021
Summary We present a case of awake tracheal intubation with flexible bronchoscopy which resulted in incorrect tracheal tube placement. The presence of a stenotic subglottic lesion with an appearance similar to the carina led to the tube being positioned with only the tip within the trachea whilst the cuff was located between the vocal cords. A capnography trace was identified before induction of anaesthesia; however, visual confirmation of the carina was undertaken in a rushed manner due to the patient becoming agitated. Once the incorrect tracheal tube placement was identified, the decision was made to wake the patient. Thereafter, a more experienced operator successfully performed awake t…
Messung des Gefäßdurchmessers zur Bestimmung von Stent- und Ballongröße bei perkutanen Eingriffen an der Beckenstrombahn
1995
AIM Should the sizes of balloons and stents used in the pelvic circulation be determined by the size of the ipsilateral or contralateral vessel? STUDY DESIGN The angiographic findings in 31 patients were analysed; in 10 an occlusion and in 21 a high grade stenosis (greater than 75%) of the common iliac artery had been treated by stenting (26) or simple PTA (5). RESULTS In 26 of the 31 patients there was marked reduction in the lumen distal to the lesion up to 40%. In 17 patients this was reversed immediately after the procedure and in five others the lumen increased but a difference between the two sides remained. The changes on the two sides following treatment were statistically significa…
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…
Optimal positioning of the humeral component in the reverse shoulder prosthesis.
2014
Total reverse shoulder arthroplasty is becoming more and more the standard therapeutic practice for glenohumeral arthropathy with massive lesions of the rotator cuff. The biomechanical principle of this prosthesis is represented by the reversion of the normal anatomy of the shoulder joint. This non-anatomical prosthesis leads to a medialization of the rotation centre of the glenohumeral joint and also to a distalization of the humeral head. All that causes a deltoid tension increasing so allowing a larger abduction of the arm. Main complications of the reverse shoulder prosthesis are due to the joint instability, the scapular notching and the wear of the polyethylene insert. The main goal o…
