1/7. Arteriovenous malformation mimicking femoral osteolysis after total hip arthroplasty.We encountered a case of apparent progressive femoral osteolysis around a well-fixed cementless implant in a young patient. At the time of revision arthroplasty, massive hemorrhaging occurred during exposure and attempted femoral component extraction. Urgent packing of the exposed endosteum with polymethyl methacrylate controlled the bone bleeding. Emergent angiography confirmed an arteriovenous malformation with extensive proximal diaphyseal involvement directly at the site of osteolysis. This arteriovenous malformation was treated successfully with selective arterial embolization and second-stage resection. In retrospect, the index arthroplasty operative note indicated an excessive amount of blood loss, and prerevision radiographs showed osteolysis with uncharacteristic vascular markings. The presence of an osteolytic lesion in total hip arthroplasty should not be assumed to be attributed to polyethylene granuloma, and any atypical radiographic features should prompt further preoperative investigations.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/7. Cementless revision of cemented stem failures associated with massive femoral bone loss. A technical note.A revision technique of the failed cemented femoral stem was developed using a standard cementless porous-coated prosthesis. The advantages of this technique are that the prosthesis has apposition to autogenic bone rather than allograft; problems of long stem can be avoided; supplementary allograft provides enough strength to allow early weight bearing; it facilitates the extraction of the distal cement; and further revision is relatively easy in the healed, viable bone bed.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/7. Premature alveolar bone loss in erdheim-chester disease.erdheim-chester disease is a rare histiocytosis also known as lipoid granulomatosis. Oral findings have not been reported previously to our knowledge. This case report documents evidence of oral sequelae of erdheim-chester disease. A patient whose course was followed for 10 years at the National Institutes of health had premature alveolar bone resorption. He underwent full-mouth extraction at age 29 years because of severe periodontitis. Histopathologic evidence of erdheim-chester disease was demonstrated in the periodontal soft tissues. In the ensuring years, accelerated resorption of the residual ridges precluded the use of conventional dentures. We recommend early preventive dental management for patients with erdheim-chester disease.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/7. Massive gingival enlargement and alveolar bone loss: report of two cases.We present two cases of massive gingival enlargement and osteolysis of alveolar bone in a 30-year-old female and a 36-year-old male. The etiology could not be established in either case. Histologically, both lesions contained hyperplastic fibrous connective tissue and intense plasma cell infiltrates. Both patients responded well to extensive gingivectomy, extraction of all teeth, and alveoplasty.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/7. Hyperbaric oxygen treatment of osteoradionecrosis of the mandible with repeated pathologic fracture. Report of a case.Treatment of patients with osteoradionecrosis of the mandible with a pathologic fracture consists in almost all cases of a continuity resection of the mandible. This leads to functional and esthetic problems that can only be solved by often extensive surgery. In this case report we present a 38-year-old woman who developed osteoradionecrosis of the mandible with a pathologic fracture 1 1/2 years after combined surgical and radiation therapy of an adenocarcinoma of the right parotid gland. The patient had a subcondylar pathologic fracture together with osteolysis in the right mandibular body, normally an indication for partial resection of the mandible. Because of the absence of denuded bone, fistulation, and the poor quality of the surrounding soft tissues, a more conservative approach was chosen. Treatment consisted of hyperbaric oxygen and dental extractions with alveolectomy with the patient under local anesthesia. During follow-up, a second pathologic fracture occurred in the region of the right first and second molar. No additional treatment was given. Six and one-half years after the initial treatment and 5 1/2 years after the last fracture, the patient is free of complaints, the fractures have healed and both esthetic and functional results are good.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
6/7. Cervicofacial actinomycosis in man.Two cases of advanced jaw destruction due to actinomyces is reported; one with diabetic diathesis and a history of tooth extraction the other had a trauma of the mandible with the fracture; good results were obtained with penicillin therapy.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
7/7. Consequences of serious oral injury associated with the congenital analgia syndrome.Three sisters at the ages of seven months, twelve years, and thirteen years presented with the initial damages to the oral tissues and the distinctive long-term effects in conjunction with the congenital analgia syndrome. The severity of this syndrome justifies the consideration of a prophylactic extraction of the primary dentition. A controlled mastication will be more likely with increasing age and eruption of the permanent teeth.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
