1/60. Lumbar intraspinal synovial cysts of different etiologies: diagnosis by CT and MR imaging.Intraspinal synovial cysts arises from a facet joint and may cause radicular symptoms due to nerve root compression. In the present study, three surgically and histologically proved cases of synovial cyst of the lumbar spine with different etiology are described. The purpose of this report is to illustrate the imaging features of various etiologies of intraspinal synovial cysts allowing a correct preoperative diagnosis. review of the literature enables us to say that to our knowledge, there is no reported article collecting the imaging findings of intraspinal synovial cysts with different etiologies. Only single cases with rheumatoid arthritic or traumatic origin have been reported to date. We believe that computed tomography and particularly magnetic resonance imaging are the methods of choice which provide the most valuable diagnostic information.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
2/60. Incomplete nondisplaced tibial osteotomy for treatment of osteoarthritic knee pain.Intraosseous venous hypertension is considered a significant factor in the production of knee pain secondary to degenerative arthrosis, thus vascular decompression by means of tibial osteotomy is a rational option for treatment of selected patients. A preliminary report is presented of six patients with symptoms of primary or secondary degenerative arthrosis who were treated by incomplete nondisplaced proximal tibial osteotomy with good or excellent results. These patients were refractory to nonoperative treatment and were not deemed suitable candidates for angulated osteotomy, arthroscopic surgery alone, or total knee arthroplasty. patients ranged in age from 36 to 61 years (mean age: 47 years). Follow-up ranged from .8 to 6.7 years (mean: 3.1 years). The subjects were studied postoperatively by interview, physical examination, radiographs, and bone scans. Results were assessed using the knee rating system of The Hospital for Special Surgery.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
3/60. Symptomatic osteoarthritis of the temporomandibular joint: report of a case.A case of osteoarthritis in the TMJ which manifested clinical symptoms, radiographic changes, and the classic microscopic alterations has been presented. Whether the condition was a primary or secondary form of the disease could not be unequivocally ascertained, as the symptoms preceded the injection of a sclerosing solution and a mandibular fracture, both of which could be significant contributing factors to a trauma-induced secondary osteoarthritic change. Nevertherless, a lack of symptoms in other joints would tend to exclude a generalized (primary) form of osteoarthropathy. In this regard, symptoms referable to the TMJ (to the exclusion of other joints) are more consistent with findings of secondary osteoarthritic change. Whether osteoarthritic changes were discernible by radiography in the TMJ before the traumatic episodes recorded in the history is unknown. Indeed, a developmental anatomic anomaly could not be ruled out. Regardless of whether the changes were the result of primary degenerative disease or chronic trauma, the symptoms were adequately resolved by surgical intervention.- - - - - - - - - - ranking = 29.745032946029keywords = fracture (Clic here for more details about this article) |
4/60. Early experience with total knee replacement.This paper presents a review of two years' experience with the geometric total knee replacement. The results of 23 arthroplasties in 22 patients are discussed. Relief of pain was consistent and dramatic, movement was increased postoperatively in only three patients, but imporvement in overall function occurred in 20 of the 22 patients. There was one failure requiring arthrodesis. In this patient, six months after surgery the medial tibial condyle collapsed and the polyethylene tibial component fractured. This complication has not been reported before. Early results are encouraging. Total knee joint replacement is a useful procedure in advanced arthritis when arthrodesis is the only alternative.- - - - - - - - - - ranking = 29.745032946029keywords = fracture (Clic here for more details about this article) |
5/60. Upper airway compression after arthroscopy of the temporomandibular joint.An unusual complication is presented following a temporomandibular arthroscopy carried out under general anaesthesia. Severe cervicofacial oedema occurred immediately after surgery which required prolonged endotracheal intubation. Retrospective analysis revealed a massive fluid escape in the surrounding tissues leading to laryngeal oedema.- - - - - - - - - - ranking = 4keywords = compression (Clic here for more details about this article) |
6/60. Hypertrophic dens resulting in cervical myelopathy: histologic features of the hypertrophic dens.STUDY DESIGN: A case report of a 43-year-old woman who had hypertrophic dens in the developmentally narrow atlas ring that resulted in cervical myelopathy. OBJECTIVES: To present histologic findings of the hypertrophic dens, which was excised en block the transoral approach, and to discuss the pathogenesis of the hypertrophic change of the dens. SUMMARY OF BACKGROUND DATA: Few cases have been reported of cervical myelopathy associated with hypertrophic dens, and there have been no previous reports describing the histologic features of hypertrophic dens. methods: Clinical data were reviewed from the patient's chart, and histologic features of the hypertrophic dens were examined in the sagittally cut section. RESULTS: After posterior decompression surgery, cervical myelopathy in the patient subsided. Myelopathy reappeared 4 years after surgery. Imaging studies showed osteoarthritis of the atlantodental joint, hypertrophic dens, and degeneration of the cruciate ligament. In the second surgery, transoral removal of the dens with posterior occipitocervical fusion was performed. Histologic studies showed thickening of the cortical bone of the anterior and cranial parts of the dens. The apical portion, which was the insertion portion of the ala ligaments, showed degenerative changes of tide marks. CONCLUSION: Atlantoaxial instability and enthesopathy were probably the causes of the hypertrophic changes of the dens in this case.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
7/60. Orthopaedic surgery in the elderly.Demographic estimations for the UK predict an increase in the number of major orthopaedic surgical procedures in elderly people. The two major indications for surgery are osteoporotic fractures and severe osteoarthritis of weight-bearing joints. Coexisting medical disease makes elderly patients a surgical high-risk group, and mortality and morbidity after emergency surgery remains high.- - - - - - - - - - ranking = 29.745032946029keywords = fracture (Clic here for more details about this article) |
8/60. Fat embolism syndrome after cementless total hip arthroplasty.There are few reports in the literature of fat embolism syndrome after cementless total hip arthroplasty (THA). Most reported cases have occurred after fracture or cemented THA. We report a case of a healthy 51-year-old woman who underwent THA for osteoarthritis under spinal anesthesia. A press-fit cup and extensively porous-coated diaphyseal locking stem were used and inserted without cement. In the recovery room, the patient became hypoxemic and hypotensive and developed cortical blindness. The next day, a petechial rash was evident. Gurd's criteria for fat embolism syndrome were fulfilled. Her symptoms resolved over a 2-week period. patients undergoing cementless THA are at risk for fat embolism syndrome, and this must be considered in the differential diagnosis for postoperative hypoxemia and neurologic deficits.- - - - - - - - - - ranking = 29.745032946029keywords = fracture (Clic here for more details about this article) |
9/60. Cervical osteophytes presenting as unilateral vocal fold paralysis and dysphagia.Any process involving either the vagus nerve, its recurrent laryngeal branch or the external branch of the superior laryngeal nerve may cause paralysis of the vocal fold. The most common cause is neoplasm. Clinically, the patients often present with a hoarse, breathy voice as well as symptoms of aspiration. The following represents a unique case of unilateral vocal fold paralysis and dysphagia caused by a degenerative disease of the cervical spine, resluting in extrinsic compression of the recurrent laryngeal nerve.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
10/60. Vertical-split fracture of mandibular condyle and its sequelae.A case of vertical-split fracture of the right mandibular condyle and its sequelae is presented. The patient was a 16-year-old female being assessed for orthodontic treatment. Orthopantomograph and plain joint view radiographs showed a remodelled condyle which had suffered trauma 10 years previously. This type of fracture is unusual in nature but has not led to any secondary lack of growth, restriction of movement or facial asymmetry.- - - - - - - - - - ranking = 178.47019767617keywords = fracture (Clic here for more details about this article) |
