These devices rely upon an xray beam that excites an image tube screen with the production of photoelectrons. These electrons are electronically accelerated to impinge on a tungsten target producing x-rays which are focused onto a phosphorus screen, producing a visible image. This image is then focused onto a television camera. It is this image that the television camera scans and converts into a composite signal. The signal is then processed and converted into digital data and stored for retrieval by the surgeon. Instantaneous image retrieval without film processing reduces radiation exposure and is the great advantage of electronic image intensification. Recent refinements in image intensification technology include Fluoroscan (Fig. l), a miniature surgical Carm designed for use in the operating suite. The Fluoroscan real time digital imaging system is a low energy, high gain x-ray unit which takes advantage of a small field of view, small objectives (i.e., extremities such as ankles and wrists), and a high gain imaging chain to provide images without the risk associated with excessive radiation dose to medical personnel or the patient. By restricting the field of view and collimating the x-ray beam through a small aperture, radiation scattered to areas surrounding the unit is minimized. A high gain imaging chain is utilized to lower the x-ray quanta necessary to form a usable image. The manufacturer claims that under typical operating conditions, radiation to surgical personnel is less than 0.0001 R/hr.","PeriodicalId":77133,"journal":{"name":"Foot & ankle","volume":"14 9","pages":"545-9"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/107110079301400912","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19300810","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}

Lack of awareness and a confusing clinical and radiological picture often lead to a delay in diagnosis. We reviewed 23 feet seen over a 3.5-year period. Most cases were children or young adults less than 40 years of age; isolated bony involvement was seen in 10 feet, with the calcaneus being involved in five cases. Articular involvement at presentation was seen in 13 cases and these cases had significantly higher delays in diagnosis. Twenty cases responded to antitubercular therapy alone while one case had to be operated (there was one fatal outcome). Complete resolution of sequestra was seen with antitubercular therapy alone. The results were better in cases with isolated bony involvement, while cases with joint involvement had residual sequelae in the form of stiffness or pain. Two patients were advised arthrodesis. Early diagnosis and antitubercular therapy is essential to prevent joint involvement from periarticular bony lesions; surgical intervention is rarely needed. A high index of suspicion has to be maintained in high risk groups like Asian immigrants. Concomitant extraskeletal lesions may not always be present.","PeriodicalId":77133,"journal":{"name":"Foot & ankle","volume":"14 9","pages":"505-13"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/107110079301400904","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19302165","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}

A number of systems are now commercially available, but comparison of the results is complicated by the different techniques employed. This paper compares the results of two studies. The first examined a large group of normal subjects using the dynamic pedobarograph. The second was identical to the first except that the EMED F system was used. The second study was carried out in order to verify existing results and to assess the clinical significance of the expected differences. Comparison of the results from the two studies showed that the median peak pressures demonstrated similar patterns with the highest pressure in the forefoot under the second/third metatarsal heads and the toes taking gradually reduced pressure from the first to the fifth toe. The EMED F showed higher peak pressures than the dynamic pedobarograph under the heel, the medial four metatarsal heads, and the great toe and showed lower peak pressures and shorter contact times under the lateral four toes. The pattern of loading across the metatarsal heads was further analyzed using an objective method of splitting the subjects into groups. Four groups were isolated from both sets of results, and this has confirmed that only a proportion of normal subjects demonstrate highest loading under the first metatarsal head whereas the remainder show highest loading centrally within the forefoot.","PeriodicalId":77133,"journal":{"name":"Foot & ankle","volume":"14 9","pages":"514-9"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/107110079301400905","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19302166","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}

A 7-micron in-shoe pressure sensor recorded the pressure under the first MTP joint in the 20 volunteers while they were wearing their normal footwear (athletic footwear), a wooden postoperative shoe, a fiberglass short leg walking cast, and a postoperative shoe with a first MTP joint cutout orthotic device. The results showed both casting, and the postoperative shoe with the first MTP joint cutout orthotic device significantly reduced pressure under the first MTP joint compared with normal footwear, with an average decrease of 31% and 43%, respectively. However, the standard postoperative shoe did not significantly reduce first MTP pressure compared with normal footwear. Certain surgeries performed on the distal first metatarsal may benefit from a diminution of loading forces encountered during normal gait. The results of this study indicate that a reduction of first MTP pressures can best be accomplished with either a postoperative shoe with a cutout orthotic device or a short leg walking cast. A standard postoperative shoe showed inconsistent results and had no statistically significant effect on decreasing the pressure under the first MTP joint.","PeriodicalId":77133,"journal":{"name":"Foot & ankle","volume":"14 9","pages":"520-4"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/107110079301400906","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19302167","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}
