Many different methods have tried for the treatment of fractures of the calcaneus in order to search for better results. But there was no general agreement on the treatment of the fracture of the calcaneus, especially involving the subtalar joint. Thirteen displaced intra-articular fractures of the calcaneus(in eleven patients) were treated by open reduction and internal fixation with a plate and screws, or Steinmann pins using a lateral and when needed, a medial approach, followed by early motion. From Feb. 1985 to June 1987, 13 feet in 11 patients of calcaneal fractures involving the subtalar joint were treated by open reduction and internal fixation at the Dept. of Orthopedic Surg., Chonbuk National University Hospital and the results were ss follows : l. Of 11 patients, 9 patients were male and 2 were femsle. 2. The main cause of frscture of calcaneus wss a fall from a height in 81.8% of cases. The spine fractures were associsted in 3 patients. 3. Of these displaced intra-articular frsctures, 3 fractures were tongue type and 9 fractures were joint depression type by Essex-Lopresti classificstion. 4. The tongue type fractures were treated with Steinmann pin and joint depression type fractures were treated with plate and screws. Anatomic reduction was obtained by open reduction snd internal fixation. 5. The average Bohler's angle was 8.1 before reduction and the aversge bohler's angle was 22.1 after open reduction. So, Bohler's angle was 14 increased. 6. After sverage seventy-two months follow-up, the assessment of result by Salama was satisfied in 76.9%-excellent in four(30.8%), good in six(46.1%)-and unsatisfied in 23.1%-fair in two(15.4%), poor in one(17.7%). 7. The surgical approach was used usually lateral approach and, when needed, a medial approach, followed by early motion. 8. The most common complication after treatment was pain on the heel snd subtalar joint.

This study was performed to investigate the distribution of endotoxin in various organs after intraperitoneal injection of E. coli homogenator(0111:B4, 3X10(9)cells/200g of body weight). Sprague-Dawley rats were intraperitoneally injected with E. coli homogenator and sacrificed 1 and 3 hours after injection. The lung, liver, and kidney were immunohistochemically stained with avidin-biotin complex method and observed by light and electron microscopy. On the light microscopy, granular deposits of reaction products of immunohistochemical stain were found on the cytoplasmic membrane of endothelial cells and some of parenchymal cells of all organs observed. Electron microscopic study revealed finely granular reaction products on the surface of endothelial cells and some of parenchymal cells. The pinocytotic vesicles of endothelial cells demonstrated reaction products in the early phase of experiment. The distribution of reaction products were prominent in the liver among three organs. The Kupffer cells showed the most sensitive and strongest positive reaction. The hepatocytes and endothelial cells revealed weak positive reaction 3 hours later. The alveolar macrophages of the lung were also positive from the early phase of endotoxemia, while the pneumocytes and alveolar septa demonstrated weakly positive reaction in the later phase. The capillary endothelium of the kidney revealed positive reaction from the early phase. According to above results, it is concluded that the endotoxin entered into the systemic circulation was captured in the liver and lung. And both mononuclear phagocytic system and endothelial cells could be activated or damaged by endotoxin.

Forty-six patients (fifty hips) underwent revisions of a total hip arthroplasty that had failed but was not associated with infection, Three of these patients had a third revision. The mean length of follow-up was approximately two years. Thirty patients reported that their condition was improved. On final roentgenographic examination showed, two loosening of the acetabular components and five of the femoral components in which there was one sympto matic loosening (moderate severe pain and probable roentgengraphic loosening) noted. The extralong stems are not necessary in all revision cases, cortical defects at the tip of standard stem obviously should require bypass the stress riser with a longer stem. If the stability can be achieved with host bone, Revision may be carried out with a relatively short stem. Significant postoperative complications as subsidence and progressive loosening were noted in seven out of the forty-six patients. We consider that extensive porocoated cementless stem or standard flute stem seem to be a better outcome in revision arthroplasty.

Despite the continually improving results of total knee arthroplasty, infection remains the most debilitating complication. The treatments of infected total knee arthroplasty were variable, but initially we removed infected implants and inserted antibiotic containing cemented spacer. Postoperatively, patients were mobilized in a 30 knee flexion state and treated with parenteral antibiotics. After control of infection was clinically and radiologically determined, we inserted PCL substitute total knee prosthesis. Five days postoperatively, patient began touch down standing exercise. We observed two cases in whom infected total knee arthroplasty had been salvaged successfully with two-stage implantation using cement spacers containing antibiotics.

Fibrous histiocytomas are characterized by a variable combination of cells with fibroblastic and histiocytic features. They exhibit a distinctive but inconstant cellular arrangement referred to as a storiform or cartwheel pattern. Considerable corfusion has enveloped these tumors as a result of their various terminology-fibrous histiocytoma, dermatofibroma, sclerosing hemangioma, fibroxanthoma, subepidermal nodular fibrosis, xanthogranuloma, giant cell tumor of tendon sheath. A histologically benign but locally infiltrating, 15 * 20cm sized, fibrous histiocytoma was found in the posterior aspect of left thigh of a 17-year-old man. The tumor was incompletely excised due to adhesion of the tumor mass to sciatic nerve and then radiation therpy was combined, Histogenesis and prognostic aspects of the tumor are discussed.
