[Arthroplasty of the elbow joint].

I Landor, P Vavrík, D Jahoda

Acta Chir Orthop Traumatol Cech. 1994; 61(2):68-76

The authors present a review on the development of arthroplasties of the elbow. Modern arthroplasties are divided into basic groups and their main advantages and disadvantages are characterized. The authors describe in detail the construction and technique of Souter-Strathclyde total endoprostheses of the elbow based on the authors' own experience. Total endoprostheses of the elbow are the only solution which can ensure at the same time marked relief from pain, a satisfactory range of movement and stability of the operated joint.

[Using of a Wagner stem in revision-arthroplasty following loosening of a total hip endoprosthesis].

C Voigt, S Zimmer-Amrheim, F Enes-Gaiao, R Rahmanzadeh

Acta Chir Orthop Traumatol Cech. 1994; 61(2):77-80

During a three-year period to 50 patients a Wagner femoral revision endoprosthesis was implanted. The mean age of the patients was 67.5 years. In 39 patients replacement of an endoprosthesis was involved, in 7 patients the indication was fracture in the area of the endoprosthesis, 4 patients were operated for other reasons. Of 44 patients, who were operated at least 12 months ago, 33 were checked. Sixteen patients were classified according to Harris' score as very good, 9 as good and in 4 the result was satisfactory or poor. Wagner's revision shank is suitable in particular in damage of the proximal femur, where in case of firm distal anchoring and...

[Long-term results of implantation of polyethylene screw sockets using Edler's method].

M Weissinger, A Keppel, C Helmreich

Acta Chir Orthop Traumatol Cech. 1994; 61(2):81-86

High-molecular polyethylene is used in many technical spheres and in orthopaedics it is used in particular as a sliding component. In orthopaedic endoprosthetics it serves as a material for the manufacture of sockets, whereby polyethylene sockets can be anchored with our without cement. Morphological research corroborates the suspicion of inadequate static firmness of the polyethylene used and this may lead to abrasion and thus mechanical loosening of Endler's screw socket and subsequently also of the metal shank. At the orthopaedic department of the General hospital in Zwettel (Austria) between 1984 and 1987 113 Endler sockets were implanted in 101...

[Retrospective study of heterotopic ossification with and without prophylactic indomethacin therapy].

M Weissinger, A Keppel, C Helmreich

Acta Chir Orthop Traumatol Cech. 1994; 61(2):87-91

The authors evaluate the problem of heterotopic ossifications as a complication of total endoprostheses of the hip joint. The classification into stages as elaborated by Arcque was used and compared with the clinical correlate. The authors compared the year 1989 when the total number of prostheses was 150 without prophylaxis of ossifications, with the year 1992 when the total number of endoprostheses was 200 with prophylaxis. In 94% of the patients starting on the second day after surgery to the 21st postoperative day 2 x 50 mg Indomethacin (2 x 1 capsule Indocin forte) were administered. As a gastroprotective drug the patients were given Ranitidine,...

Custom made total knee-replacement in patients with primary and secondary bone tumors.

H Rechl, I Schittich, W Plötz, J Träger, R Gradinger, R Burgkart, S Reeg

Acta Chir Orthop Traumatol Cech. 1994; 61(2):92-96

The authors present an account of a group of 51 patients to whom an individual endoprosthesis of the knee joint was implanted on account of a tumour. A primary bone tumour was involved in 42 cases and a metastatic process in 9 cases. Twenty-four endoprostheses were cemented, 26 were implanted without cement. The mean follow-up period was 43 months. Functional results excellent and good in 61%, poor results only in 5%.

[The Kessel-Gschwend approach to the shoulder joint].

T Trc

Acta Chir Orthop Traumatol Cech. 1994; 61(2):97-100

The solution of pathological conditions in the subacromial space is essentially not only a diagnostic problem but also a problem of the surgical approach. Exposure of the necessary space is practically always associated with slackening of the muscles; usually the deltoid muscle is affected which leads to hypotrophy, frequently to muscular atrophy with an adverse impact on the function of the shoulder joint. Gschwend's modification of Kessel's approach reduces muscular hypotrophy and the risk of damage to a minimum and permits to treat the described affections of the shoulder joint, with rapid restoration of normal function of the joint. The approach...

[Rehabilitation after anterior cruciate ligament suturing].

M Andrtová, I Chlupatá

Acta Chir Orthop Traumatol Cech. 1994; 61(2):101-102

The authors discuss problems of rehabilitation after suture of the anterior cruciate ligament where frequently errors are committed and where inadequate rehabilitation may cause damage to the patient. Different periods of rehabilitation after LCA sutures are discussed and suitable methods of exercise for different periods are recommended.

Current state of cementless hip prostheses.

E Hipp, H Rechl, W Plötz, S Reeg, J Träger

Acta Chir Orthop Traumatol Cech. 1994; 61(2):103-108

Cemented cups in the young patient continue to show an unacceptable rate of early aseptic loosening. A well designed cementless prosthesis, implanted with good technique, is a better alternative. With the uncertainty surrounding the femoral stem, a hybrid total hip with a cemented stem and porous ingrowth cup remains an acceptable interim solution. There is an ongoing problem with the wear debris produced by the available implant materials. There is hope that the newer materials will help in this regard. Custom made prostheses at this time, seem most suited for those hips with marked deformity making the use of standard systems difficult. The use of...

[Transpedicular stabilization in fractures of the thoracolumbar spine. II].

J Bartonícek, J Stehlík

Acta Chir Orthop Traumatol Cech. 1994; 61(2):109-122

Proceeding from the literature survey and on the basis of his own experience the author presents a current concept review of the problems of the transpedicular stabilization in fractures of the thoracolumbar spine. Individual chapters are devoted to the biomechanics and transpedicular screw placement, classification of implants and to the transpedicular operations on the injured vertebral body. Based on both his own experience and survey of the literature the author recommends the following: in order to increase the stability of osteosynthesis to place transpedicular screw in anteromedial direction (Magerl approach) close to the anterior cortex of...
