Abstract Articular cartilage homoeostasis is critical for joint function. The steady state homoeostasis of articular cartilage matrix composits (above all collagen type II and proteoglycans) is a balance be-tween anabolic morphogens such as cartilage derived morpho-genetic proteins. Cartilage composites of superficial tangential zone, middle zone, deep radial zone, tide mark and subchondral bone. The superior zone is rich on radial orientated collagen fibers. This causes a high mechanical resistance against pressure and shear forces. The deep layers contain more proteoglycans and water. This creates a preload for the collagen fibers as well as neutralizes pressure forces too. The matrix turnover is regulated by cytokines which activate matrix metalloproteinases. The biomechanical property of cartilage is characterized by vis-coelasticity. Cartilage degeneration is caused by the increase of katabolic processes. There is a decrease of matrix composites like collagen type II and proteoglycans. The increases of water content products the edema and the chondrocytes become apoptop-tically. This is conformed by a decreased mechanical resistance. The cartilage defects results from this loss of mechanical properties. Secondary are damages within the subchondral bone and the synovia. This is characteristically for the osteoarthritis.","PeriodicalId":75462,"journal":{"name":"Aktuelle Traumatologie","volume":"17 1","pages":"195 - 207"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-2006-924754","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58063225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Loss of mobility is associated with a high lethality rate. The reduced quality of bone due to age is another challenge in the treatment of those fractures. Our study should resolve if the gliding nail (GN) lives up to the particular requirements of surgical treatment of per- or subtrochanteric femoral fractures in the elderly patient. Materials and Methods: We analysed the data of 92 patients with unstable pertrochanteric and 8 patients with subtrochanteric fractures of the femur treated with GN osteosynthesis. The data was collected and analyzed in a retrospective manner. Results: Mainly geriatric patients of female sex were affected. 71% of the patients suffered from osteoporosis. In 80 cases the Standard GN was inserted. Assisted mobilisation of the patients began on the 1 st postoperative day. A follow-up examination was possible in 83 cases after a median time of 0.8 years, 17 patients died during follow-up. The preoperative level of mobility was regained in 60 patients. Two patients became bed-ridden and therefore lost their social independency. The most frequent implant-related problem was dislocation of the double-t femur neck blade (n = 6; 7%) mostly occurring in patients with diminished cancellous bone in the femoral neck. Discussion: Our clinical results reflect the biomechanical properties of the GN in the treatment of unstable per- or subtrochanteric fractures of the femur in diminished bone quality. We therefore recommend the device for creating full weight bearing osteosynthesis in these types of fractures.","PeriodicalId":75462,"journal":{"name":"Aktuelle Traumatologie","volume":"36 1","pages":"159-165"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/S-2006-924585","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58062235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forceps/vacuum were not used. Absence of active movement of the right shoulder and an undisplaced mid-third fracture of the clavicle were observed before discharge. Finger movements were normal. The first diagnosis was obstetrical Erb’s paralysis and clavicle fracture. At the 14-day follow-up, swelling and point tenderness above the clavicle resumed while right ipsilateral elbow was swollen without direct signs of trauma. Passive elbow movement in a range of 20– 908 was possible if done very gently. Radiographs (Fig. 1 a and b) showed the radius and ulna were not in alignment with the distal humerus. Radiographs of the opposite elbow were normal. Perinatal child abuse was ruled out. An ultrasound (US) of the elbow was obtained with a 7.5 MHz linear transducer. The examination was consistent with physeal separation of the distal humerus with posterior and medial displacement. On longitudinal view one can see the periostal elevation while the subperiostal space in the distal humerus is seen to be hyperechogenic thus being consistent with incipient callus. The transverse view showed posteromedial physeal displacement (Fig. 2 a and b). The standard sonographic examination should include examination of the controlateral elbow.","PeriodicalId":75462,"journal":{"name":"Aktuelle Traumatologie","volume":"36 1","pages":"183 - 186"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-2006-924588","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58062346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
