High-dose immunoglobulins (IVIG) are important agents in the treatment of numerous autoimmune disorders. In the field of dermatology, increasing numbers of patients with bullous autoimmune disorders and mixed connective tissue diseases have been treated. We successfully treated a patient with pemphigus vulgaris with IVIG, after he had developed osteonecrosis of his right femoral head while on azathioprine and corticosteroids. After reduction of oral corticosteroids, his disease flared dramatically. The addition of a high dose immunosuppressive regimen including azathioprine and dapsone failed to help. Thus high dose IVIG (2 mg/kg, 4 weeks interval) therapy was initiated and induced complete…
Analyse der Pfannenveränderungen bei Morbus Perthes mittels Radiomorphometrie
2005
AIM Decreases in depth and irregularity are typical changes of the acetabulum in patients with Perthes disease and develop secondary to the femoral head involvement. Optimal timing of therapy plays an important role to prevent these secondary changes. The present study investigates the influence of the amount of femoral head involvement and the patients' age on the acetabulum and the outcome. METHODS 66 patients with 76 affected hip joints were included in the study. 20 hips had a conservative therapy, 22 an operative therapy (IVO). 34 hip joints underwent a conservative therapy at first, followed by an operative intervention. The radiomorphometric analyses at the time of diagnosis, pre- an…
Ergebnisse zementfreier Endoprothesen bei der nichttraumatischen Hüftkopfnekrose
2001
AIM OF THE STUDY The results from 56 patients with osteonecrosis of the femoral head who underwent 66 uncemented total hip replacements were analyzed and compared with current reports in the literature on cemented endoprosthesis. METHODS In the retrospective study in 30 of those cases the Zweymuller and in 25 cases the HA-coated ABG prosthesis were used. In addition the results of 11 patients with a polyethylene Endler cup in combination with a Zweymuller stem are presented. The mean age at surgery was 48 years, the mean follow-up was 5.9 years. Clinical examination, registration of the Merle d'Aubigne score and a radiological examination were performed. RESULTS The clinical results did not…
Acetabulumfrakturen im Alter
2002
Acetabular fractures in elderly patients are rare injuries, but their incidence is increasing. Poor bone quality due to osteoporosis and an increased operative risk due to concomitant disease are factors complicating surgical therapy. Literature does not provide generally accepted treatment protocols. In a 4-year period, 27 patients who were 65 years or older and who had an acute displaced fracture of the acetabulum were admitted to our department. Four minimally displaced and stable fractures were managed conservatively. Internal fixation was performed in 16 cases. According to the Merle d'Aubigne score, in 15 out of 18 surviving patients excellent or good results were found. Treatment str…
Langzeitergebnisse nach Versorgung medialer Schenkelhalsfrakturen mit Keramikkopfendoprothesen
1996
Total hip replacement is often recommended for the treatment of femoral neck fractures in elderly patients. A less invasive approach with shorter operating time is the replacement of the femoral head only, leaving the acetabular cartilage in situ. Hemiarthroplastic hip replacement using a metallic head prosthesis was not successful in the past, because the majority of patients developed protrusio acetabuli after surgery. In the present study hemiarthroplastic hip replacement using an Al2O3-ceramic head was shown to be a useful method for the treatment of femoral neck fractures in elderly patients. From 1985 to 1990 277 patients were treated with hemiarthroplasty. The average age at the time…
Rationelle bildgebende Diagnostik von Becken- und Azetabulum- verletzungen
2000
In spite of the widespread availability of CT scanners, conventional X-ray radiographs remain the basic imaging modality in patients with pelvic and/or acetabular trauma. However, the extent of their use will depend on local utilities (e.g., availability of CT scanners) and on the patient's clinical condition. Regarding the inaccuracy of conventional radiography in the diagnosis of injuries of the dorsal pelvic ring and of the acetabulum, computed tomography represents the most important imaging modality in the clinically stable patient. CT provides an exact staging of the extent of trauma and allows for differentiation of pelvic instabilities. CT clearly demonstrates the severity of acetab…
Cement augmentation for trochanteric fracture in elderly: A systematic review()
2021
Abstract Background Cement augmentation of internal fixation of hip fracture has reported to improve fracture stability in osteoporotic hip fractures, reducing the risk of cut-out of the sliding screw through the femoral head. The purpose of present study was to perform a systematic literature review on the effects of augmentation technique in patients with osteoporotic hip fractures. Material and methods A comprehensive literature search was systematically performed to evaluate all papers published in English language included in the literature between January 2010 and July 2020, according to the PRISMA 2009 guidelines. In vivo and in vitro studies, case reports, review articles, cadaveric…
MRI of transient osteoporosis of the hip.
1991
Among the available imaging techniques such as conventional radiography, radionuclide bone scan, and computed tomography (CT), magnetic resonance imaging (MRI) has made significant contributions to the diagnosis of acute hip joint disease in adults by enabling early differentiation between such conditions as idiopathic avascular femoral head necrosis, septic coxitis, degenerative disease, and tumors. In this study we investigated the use of MRI for evaluation of patients with transient osteoporosis (TO). MRI with T1- and T2-weighted sequences in coronal, transverse, and sagittal sections was performed in 12 patients with retrospectively confirmed TO, both at the onset of the disease and lat…
Zur Diagnostik der transitorischen Osteoporose der Hüfte und deren Darstellbarkeit in der MR-Tomographie
2008
Magnetic resonance (MR) imaging may distinguish transient osteoporosis of the hip from more severe hip diseases. 12 patients with transient osteoporosis of the hip underwent MR imaging. The initial and follow-up studies included T1- and T2-weighted images in coronal, transverse or sagittal planes. There were revealed 3 stages: diffuse-, focal-, and residual stage. This syndrome is characterized by hip pain, limping, and osteoporosis of the femoral head with preservation of the joint space. The clinical symptoms and abnormalities on MR images disappeared completely within 6-10 months.
