Acta Chir Orthop Traumatol Cech. 1994; 61(5):260-263

In the first part of our paper innovations as regards the non-cemented endoprosthesis of the hip joint by Zweymüller's method are described. As a special advantage the double cone of the socket is mentioned which as to its anatomical shape is close to the acetabulum and makes only slight resection of the bone on the floor of the acetabulum possible. At the Orthopaedic Department of the hospital in Zwettl between 1984 and 1987 more than 100 polyethylene Endler screw sockets were implanted. From the end of 1987 to the beginning of 1993 the authors used non-cemented endoprostheses as designed by Zweymuller. Based on the mentioned advantage of the new...

[Initial experience with percutaneous lumbar nucleotomy and discoscopy.].

M Weissinger, A Keppel, C Helmreich

Acta Chir Orthop Traumatol Cech. 1994; 61(5):264-267

Ever since percutaneous lumbar nucleotomy and discoscopy were introduced great hopes in this method were raised by specialists and patients. Based on the initial euphoric comments in the professional press, the authors started to use this procedure in 1992. During the period between Jan. 1 1992 and Dec. 31 1993 at the orthopaedic department of the General Hospital in Zwettel 69 operations of the disc were performed. The number comprised 62 conventional nucleotomies and 7 percutaneous nuc-leotomies combined with discoscopy. The mean follow-up period in patients with percutaneous nucleotomy and discocopy was 14 months (3-24). With regard to preoperative...

In this work the change of stress distribution in the hip joint articular surface after shifting of the upper part of the body towards the painful hip due to pain reflex is estimated theoretically by using a three dimensional mathematical model. It is shown that after displacement of the upper part of the body towards the painful hip the stress in the hip joint can be in case of poor femoral head coverage and small inclination of the pelvis very little decreased in spite of the fact that the resultant hip joint force is reduced considerably. Key words: stress in the hip joint, body shitting.

[Ischaemic Post-dislocation Necrosis of the Head of the Femur: Possibilities of Surgical Treatment (Part II: Surgical Procedure at the Orthopaedic Clinic in the Faculty Hospital in Motol).].

V Smetana, P Chládek

Acta Chir Orthop Traumatol Cech. 1994; 61(5):271-275

This part of the paper is based on the theoretical background and principles of conservative and surgical treatment described in part I. The authors describe the principle of operation and give a detailed account of it, supplemented by diagrams. In the discussion the authors mention views regarding the type and scope of surgery with regard to the assumed increased pressure exerted on the head of the femur, and also changes of the ratio of forces in the femur are discussed. Key words: inborn dysplasia of the hip joints, ischaemic necrosis, surgical treatment.

[Value of peroperative biopsy in the diagnosis and treatment of musculoskeletal tumors.].

V Trnka, Z Matejovský

Acta Chir Orthop Traumatol Cech. 1994; 61(5):276-278

In the period 1982-1992 the authors have performed 1276 peroperative biopsies from frozen sections in 607 patients with suspect diagnosis of a musku-loskeletal tumor. In 174 a diagnosis of a primary malignant tumor was established, in 166 of a benigne tumor, in 53 of metastasis, in 104 of a tumor-like lesion, in 33 of an inflamation. In 77 patients (12,6 %) it was not possible to establish peroperatively the diagnosis and it became necessary to wait for the definite histological examination. Gaining a peroperative histological diagnosis makes an immediate start of preoperative chemotherapy in osteosarcoma and Ewing's sarcoma possible. In chondrosarcoma...

[Epidemiology of damage of the meniscus in miners.].

J Musialek, Z Kostál

Acta Chir Orthop Traumatol Cech. 1994; 61(5):279-281

The authors evaluated the health records of men treated by open arhtrotomy because of damage of the menisci of the knee joint in the Municipal Hospital in Ostrava in 1988-1989. The group was formed by miners working underground and a second group of patients who were not miners. The stratification of the two groups was made by age, circumstances under which the first symptoms developed, the surgical macroscopic and microscopic picture. The annual incidence in the miners' group was 25.6, while it was 6.2 in the comparable group. A significantly higher incidence was recorded in the group of 20 - 29 year olds in favour of the miners (36.7 % and 23.7 %,...

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

J Vojtassák, F Makai, K Rausová, A Svec, R Vojtek

Acta Chir Orthop Traumatol Cech. 1994; 61(5):282-289

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. Primary coxarthrosis accounted for 48%, bionecrosis of the head for 21%, deforming coxarthrosis (condition following LCC) 12%, rheumatoid arthritis 9%,...

[Assessment of the Costal Hunch by a Scoliosometer to Predict Cobb's Angle in Idiopathic Scoliosis.].

J Blaha, E Ettlerová

Acta Chir Orthop Traumatol Cech. 1994; 61(5):290-292

The investigated group comprised 207 patients treated at the spondylologic consulting centre of the orthopaedic clinic where 576 assessment were made with subsequent computer evaluation. Mathematically the correlation between the angle of the costal hunch assessed by a scoliosometer and Cobb's angle on the X-ray picture was calculated. The value of the correlation coefficient was 0.8049. For statistical processing of the results of measurements the authors used the method of robust regression and an equation was calculated according to which the prediced values of Cobb's angle Y were calculated. These results were listed in a table for the extent of...

[Absorbable materials in orthopaedic surgery.].

G Vasko, L Jencíková

Acta Chir Orthop Traumatol Cech. 1994; 61(5):293-294

The authors discuss the use of biodegradable in vivo absorbable osteosynthetic material BIOFIX manufactured by BIOSCIENCE Ltd. Tampere Finland. They describe its composition, indications, contraindications of its use, possible complications as well as advantages of its use in orthopaedics, traumatology and microsurgery. They present their initial experience with osteosynthesis of fractures with Biofix in the talocrural joint, shoulder and elbow. Key words: fractures of the ankle, osteosynthesis, Biofix.

[Reasons for repeated hospitalization of patients with alloplasty of the hip joint.].

J Palarcík

Acta Chir Orthop Traumatol Cech. 1994; 61(5):295-297

The submitted paper is an analysis of 143 patients with cervicocapital femoral endoprostheses (CCP) and 230 patients with total endoprostheses of the hip joint (TE) operated in the Research Institute of Traumatology and Special Surgery in 1985-1990 with special attention paid to reasons for their repeated readmissions. Admissions, the necessity or probability of which was obvious already during the first hospitalization (immobilization on account of instability, extraction of metal after synthesis of the greater trochanter, infection detect during first hospitalization) were not included in the group. Only in one third (31 %) in the CCP group and in...

The authors demonstrate a relatively rare case of spontaneous healing of the navicular bone almost four years after the injury. They draw attention to diagnostic difficulties in acute injuries of the wrist and in the diagnosis of a pseudoarthrosis of the navicular bone. Key words: navicular bone of the wrist, pseudoarthrosis of the navicular bone.

[Initial experience with postgraduate specialization of nurses from orthopaedic departments.].

I Müller, K Musilová

Acta Chir Orthop Traumatol Cech. 1994; 61(5):309-311

In the Institute for Postgraduate Training of Health Workers in Brno the first three-semester course of nurses working in orthopaedic departments was held in 1991-1993. Of 25 participants 19 nurses completed the course with honours. In the submitted article the syllabus of the course is given with emphasis on new views on nursing (in particular basic care and specialized nursing care, therapeutic care and psychosomatic care and management in the health services). Teaching calls for close interdisciplinary collaboration of doctors, teachers of nursing, psychologists, lawyers, and other specialists. Those who passed this course are candidates for leading...
