Pavlik's method: a retrospective study.

This retrospective study of the early work of Arnold Pavlik in the treatment of developmental dysplasia of the hip proves the success of his method in eradicating avascular necrosis (AVN) resulting from other modes of treatment. Authors analyzed some 100 charts of children treated for CDH, as it was known at that time, between 1969 and 1981, and assessed the influence of gender, clinical stability, severity of X-ray pathology and age at which treatment was started, according to duration, outcome of treatment and rate of AVN. Of the 100 children with 134 treated pathological hips, 62 children with 86 pathological hips were treated exclusively by Pavlik's method.

Present status of screening and prevention of developmental dysplasia of the hip in the Slovak Republic.

The authors analysed the status of screening and prevention of developmental dysplasia of the hip in the Slovak Republic on the basis of the European Pediatric Orthopaedic Society questionnaire. The questionnaire was sent to 31 heads of orthopaedic departments, with 23 (74%) responses. According to the responses received, in the Slovak Republic a neonatologist or orthopaedic surgeon, depending on availability, makes the first clinical examination of the hips up to the fifth day after delivery.

[Somatometric and impedance measurements of the lower extremities in orthopedics].

Purpose Of The Study: The objective was to demonstrate the contribution of somatometry and vascular impedance measurement to the evaluation of somatic status and nutrition, particularly the state and function of the vascular system of lower extremities, in patients with arthropathy of the weight-bearing joints.

Material: Impedance plethysmography and impedance phlebography appeared to be the best methods for assessment of vascular hemodynamics; pulse oxymetry, carried out on toes, was most convenient for measurement of haemoglobin saturation with oxygen (HbO2). The state of vessels was determined according to the CEAP classification.

[Giant cell tumor--osteoclastoma: part II].

Authors present current views on the comprehensive diagnostics, treatment and prognosis of giant cell tumours. They include an exact algorithm of diagnostics necessary for a timely treatment. They describe an often unexpected behaviour of these tumours which is frequently active and aggressive, to a small extent these tumours show the tendency to become malignant.

[Results of application of hydroxyapatite and hydroxyapatitecollagen.].

The authors present their experience of the application of hydroxyapatite and a composite-hydroxyapatitecollagen in 2 groups of patients. In the first group they evaluate the mediumterm results in 10 girls and 8 boys of average age of 12,5 years after the filling of bone defects in case of bone cysts, aneurysmatic cysts, fibrous cortical defect and eosinophilous granuloma. Hydroxyapatite was applied in the form of rolls, small bricks, strips.

[Our Experience in the Revision Surgery of THR.].

The authors present their experience in the revision surgery of THR. Most often it was the case of aseptic loosening of the acetabulum, the femoral component or both components (67 %), lytic radioluscence or even lysis in the region of implants, fissures even fractures of the femur and septic loosening. They evaluate the results of revision surgeries of THR for a 5-year period in 106 patients after Merle dAubigne and Postel: excellent result was achieved in 33 %, good in 39 %, average in 19 % and a poor result in 9 %.

[Arthroplasty according to colonna - 1999.].

Authors evaluate results of arthroplasty according to Colonna.The surgery was performed at the Ist University department of orthopaedics in Bratislava in the period of 1955-1973. Of 97 patients (123 hips), 64 (79 hips) were followed up 5-25 years and 23 (31 hips) over 25 years.

[Somatometric and Hemodynamic Measurements after the Total Replacement of Weight Bearing Joint in Preventive Administration of Low-molecular Heparines.].

The authors present outcomes of simple somatometric and impedance measurements of the condition of venous hemodynamics after the total replacement of weight bearing joints with a simultaneous prophylactic application of low molecular heparines (LMH). Measurements in a group of 125 patients (86 females and 39 males) showed increase of circumferences up to symptoms of a swelling on proximal portions of the limb operated on in an early postoperative period; as a rule it reached its peak between 6th and 8th day with a subsequent subsidence in the next period, i. e.

[Acetabular Replacements in THR in Dysplastic Osteoarthritis of the Hip.].

The authors present different options of the surgical treatment of dysplastic osteoarthritis of the hip. For the acetabular replacement they use Harris-Galante, Zweymúller and Balgrist cementless cups. They evaluate results for a five-year postoperative period in 182 patients.

[Primary intraosseous liposarcoma - case report.].

Primary intraosseous liposarcoma belongs to exceptional tumors rarely found on the sceleton. There are only several tens of cases described in literature and they are published as case reports. Because there is not enough experience, especially with diagnostics of this illness, it happens that it is considered as malignant fibrous histiocytoma, malignant mesenchymoma or with secondary infiltration of liposarcoma of soft tissue into the bone.

[Osteoarthropathies and conditions after alloplasties of the knee joints from the aspect of antropometric examinations.].

The authors submit an analysis of the nutritional status assessed by anthropometric methods in a clinical group of 70 patients (mean age 58 years) where on account of the X-ray and the clinical finding of arthritis of the knees an alloplastic operation was performed. The results of the examination are compared with the analysis of the nutritional status of a group of 20 without X-ray and clinical signs of arthritis of the knee. The patients belonged to a similar age bracket.

[First results after implantation of an individual endoprosthesis of the coxa according to aldinger.].

In the introduction of the paper the authors draw attention to the advantages of individually made total endoprostheses of the hip joint (TEP). They mention three reasons which made them implant individual TEP, as described by Aldinger, i. e.

[Results of surgical synovectomy of the knee joint in patients with rheumatoid arthritis.].

The authors evaluate the results of synovectomy of the knee in 216 patients (83 men and 133 women) with rheumatic arthritis (RA); 35 patients with juvenile chronic arthritis (JCA) in the evaluated group account for 16,2%. On average 2.3 years have elapsed since the operation.

[Advantages of digitalization and analysis of roentgenograms of bones by microcomputer.].

The creation of an experimental group for digitalization of two-dimensional X-ray pictures of bones was the starting point for the application of selected procedures for their computer-assisted analysis. During processing of the picture first the primary digitalized picture was corrected (e. g.

[Mineralization of the Coxa (DPX) before Implantation of TEP.].

The authors point out that when TEP are planned more attention is paid to the type of prosthesis, its composition and technical parameters and less attention to the quality of osseous tissue which is the subject of the present work. The authors examined at the First Orthopaedic Clinic Medical Faculty Comenius University Bratislava by means of a densitometer LUNAR DPX L the neck of the femur in patients before implantation of a TEP. They examined 96 coxae in patients with an average age of 57 years.

[Indications for transposition of the greater trochanter.].

The greater trochanter participates by its anatomical structure mainly in the function of the coxa, lumbar spine and has an impact on standing and gait. In case of morphological deformities its static and biomechanical functions are inadequate. One of the possible ways of adjusting the anatomical shape of the greater trochanter, if deformed, is its isolated transposition in case of trochanter altus.

[Salmon calcitonin nasal spray and calcium sandoz forte in the prevention and treatment of osteoporotic fractures in postmenopausal women (information on clinical trial).].

At the First Orthopaedic Clinic in Bratislava, Hlboká 7, since August 24, 1992 a clinical trial is under way which is focused on the effectiveness of treatment with salmon Calcitonin (Miacalcic Sandoz) and calcium (Sandoz) in postmenopausal osteoporosis. On the above mentioned day Sandoz Co. supplied the Clinic with a densitometer Lunar DPX-L working on the principle of double X-ray absorptiometry.

[Implantation of 110 total hip joint endoprosthesis using the Zweymüller method].

The authors discuss in the submitted paper the advantages and disadvantages of cemented and non-cemented endoprostheses, type Zweymüller. They evaluate the medium-term results (one half to 5 years) after surgery in 92 patients from a total of 121 operations in 110 patients (11 bilateral). As to indications, the first place was held by so-called dysplastic coxarthroses, followed by post-traumatic coxarthroses and rheumatoid arthritis incl.

After a brief introduction the author expands on specific problems in patients with rheumatoid arthritis and indications of rheumo-orthopaedic operations. He gives an account of the main objectives of these operations, i.e.

[Comparison of surgical and radioactive synovectomy in various disorders of the knee joint].

The authors evaluate after an interval of 1-20 years the long-term results of surgical synovectomy in 454 patients and radioactive synoviorthesis in 528 patients performed at the First Orthopaedic Clinic, Medical Faculty, Comenius University and Faculty Hospital in Bratislava and at the Orthopaedic and Traumatological Clinic of the Medical Faculty in Martin in 1969-1991. The most frequent diagnosis in surgical synovectomy is rheumatic synovitis in radioactive synovectomy arthrotic synovitis (47.6% and 68.

[Experience with Implantation of TP of the Coxa in Osteoporosis.].

Based on X-ray pictures, the authors evaluate the state of osteoporosis by means of bone indexes after implantation of a total prosthesis of the hip joint. They correlate the state of osteoporosis found in the patients with the clinical condition. After 5 years following implantation of TP they found a minimal progression of osteoporosis without restriction of the function of TP of the coxa.
