To solve this problem, we developed an implantable plate which creates multiple contact points between plate and bone, called the multi-point contact or MPC plate. In an experimental animal study conducted on 16 Göttingen minipigs we investigated the bone reaction beneath 2 different types of osteosynthesis plates: the conventional type with a flat interface versus the multi-point contact type. Both epiperiostal and subperiostal plating was performed on pig's intact tibiae. After an implantation period of 16 weeks, the results were documented and compared. It was shown that the osteal remodeling activity of the cortical bone adjacent to the plate increased under both plates up to the twelfth week, but declined towards the end of the study period. Compared to the MPC plate, a conspicuous remodeling front accompanied by porosis of the cortical bone adjacent to the plate was found underneath the conventional osteosynthesis plates with a flat surface-to-bone interface. The different subimplant reactions between the 2 plates can be best explained by the fact that intracortical implant-induced viscoelastic osteocyte diffusion is better under the MPC plate, whereas it is impaired under the conventional flat plate.","PeriodicalId":29789,"journal":{"name":"Unfallchirurgie","volume":"23 6","pages":"227-37"},"PeriodicalIF":0.8,"publicationDate":"1997-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02628919","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20408596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dislocated fractures of the forearm frequently cause problems because of their poor reduction and retention. In such cases, exclusively conservative treatment requires reduction and change of therapeutical approach to avoid functional limitations resulting from axial malpositioning. The sincere contact of bone fragments, accompanied by sufficient anatomical axial and conservative reduction techniques that maintain parossal perfusion as well as a limited osteosynthesis plate contact should be the aim of the operative strategy. The use of a new titanium osteosynthesis plate system with multi-point contact between bone and plate promotes the incorporation of vessels and callus formation at the bone-plate interface and leads to the realization of the aforementioned aim, which was revealed in animal studies before. In order to examine the results, 18 patients with forearm fractures were studied, which underwent reduction and internal fixation using this new titanium osteosynthesis plate, the multi-point contact plate (MPC) system. In these patients, functional and radiological results after plate removal were studied. Our initial clinical experiences with the MPC-plate for internal fixation confirm the animal study results. The in-growth of parossal vessels into the multiple inter-point spaces enhances the subimplant (bio-logical) formation of callus, which can be visualized radiographically and intraoperatively after plate removal. These results indicate that the MPC plate has marked advantages over conventional plates.","PeriodicalId":29789,"journal":{"name":"Unfallchirurgie","volume":"23 6","pages":"238-45"},"PeriodicalIF":0.8,"publicationDate":"1997-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02628920","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20408597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surgical treatment was done in 6 cases during the last 10 years in our department; in 5 cases the dorsoradial part, in one case the dorsoulnar part of the hood was injured. The tear extended longitudinal or diagonal through the transverse fibers of the hood. Respecting the accident mechanism there have been reported tangential forces at the extensor tendon hood and forced ulnar deviation in the bended metacarpophalangeal joint. A jerky dislocation of the extensor tendon to the ulnar side of the metacarpophalangeal head during increased bending of the metacarpophalangeal joint, sometimes with ulnar abduction of the longfinger, leads usually to the diagnosis. Misdiagnoses of cases sent to our department were: \"trigger finger\" and \"recurrent dislocation of the metacarpophalangeal joint\". Once the presurgical diagnosis was \"rupture of the extensor tendon\" because of a permanent extension deficit in 30 degree position of the metacarpophalangeal joint. Treatment is always surgical with suture of the hood and immobilization of the metacarpophalangeal joint in extension position for 4 weeks.

Concerning any skeletal abnormality associated with changes in local perfusion, exudation and metabolism, it is a sensitive functional imaging procedure to detect bony disease. However, because of the varying causes of bony disease, it is characterized by a low specificity. Further, specificity may be enhanced, when patient history, clinical and lab results as well as results obtained from other diagnostic imaging procedures are combined with the result of skeletal scintigraphy. On the other hand, it is known that metabolic abnormalities of the skeleton depicted by radionuclide imaging occur much earlier than structural changes visible on X-ray imaging. Beside skeletal scintigraphy, antigranulocyte antibody or labelled leucocyte imaging may greatly assist in the detection of inflammation or infection following joint replacement surgery, respectively. Ultimatively, a combination of clinical, lab and imaging results including radionuclide imaging may represent the best approach to answer some questions asked by surgical traumatologists.","PeriodicalId":29789,"journal":{"name":"Unfallchirurgie","volume":"23 6","pages":"252-61"},"PeriodicalIF":0.8,"publicationDate":"1997-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02628922","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20408599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to assess the surface doses of the primary surgeon with and without lead shield of the thyroid we performed in vitro measurements during operative procedures of the lower extremities simulating different intraoperative situations under fluoroscopic control. The average registered ionizing dosage without thyroid shield was 70 times higher compared to the measurements with thyroid protection. In a previous study we found average fluoroscopy times during intramedullary nailing of tibia and femur of 4.6 min per procedure. Extrapolation of this value leads to the result, that even when 1000 intramedullary nailings were carried out without wearing lead protection, 13% of the dose limit recommended by the International Commission on Radiological Protection for the thyroid of 300 mSv per year would not be exceeded, whereas by wearing the lead protection only 0.2% of the recommended dose would be reached.","PeriodicalId":29789,"journal":{"name":"Unfallchirurgie","volume":"23 6","pages":"246-51"},"PeriodicalIF":0.8,"publicationDate":"1997-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02628921","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20408598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
