Acta Chir Orthop Traumatol Cech. 1989; 56(5):377-390

The work deals with the structure, chemical composition and physical properties of individual types of collagen of which thirteen has been so far described. Special attention is devoted to the types of collagen II, VI, IX and XI which are found in the articular hyaline cartilage. The main collagen type of the articular cartilage is type II which makes up approximately 90 per cent of all the collagen. The remaining three types fall into the so called minority types. Collagen of type IX differs from other types by the kink in its structure. This type of collagen represents a certain transition to proteoglycans with regard to the fact that the lateral...

[Surface bioactive ceramics (preliminary report)].

Acta Chir Orthop Traumatol Cech. 1989; 56(5):391-397

The Research and Development Institute of Industrial Glass in the town of Teplice (North Bohemia) has developed bioceramics (BAS-O) with presupposed surface activity manifested during its implantation in the macroorganism. The test was carried out by means of Macor inert ceramics produced by Corning Co. In total there were performed 8 implantations of surface active bioceramics and 7 implantations of inert ceramics in the tibiae and femurs of four dogs. After two months the experimental animals were sacrificed and the implants were examined. All eight prisms of BAS-O surface active ceramics were firmly connected with the bone and could be removed from...

[Surgical lengthening of the femur using the Poldi 7 device].

Acta Chir Orthop Traumatol Cech. 1989; 56(5):398-407

The work presents the evaluation of longterm results of the surgical prolongation of the femur. The examined group includes 10 patients: 5 boys and 5 girls which the authors treated in the years 1978-1986. Their average age in time of operation was 15.5 years. The youngest was 8 and the oldest 25 years old. Shortening was in 4 cases caused by poor healing of the fracture, in three cases it was a results of congenital hypoplasia of the femur or the whole lower extremity, in three cases it was caused by osteomyelitis. The duration of the prolongation was on average 4 months, the external fixation device was removed on average after 8 months. The mean...

[Calcaneonavicular coalition and its treatment].

P Dungl

Acta Chir Orthop Traumatol Cech. 1989; 56(5):408-418

The work deals with calcaneo-navicular coalition which occurs most frequently. The clinical picture is discussed of this congenital defect which is usually manifested by the peroneal spastic flatfoot in the period around 10th year of age and biomechanics of the foot with this anomalous coalition is dealt with. As for therapy the authors recommend surgical resection of the bony bridge between the calcaneum and the navicular with subsequent filling of the defect by a muscular flap of the short extensor of toes as recommended by Bentzon in 1928. Proceeding from their own material the authors evaluate the effect of this operation in 6 feet. In obsoleta...

[Helal's oblique subcapital metatarsal osteotomy].

M Lutonský, P Hroch, J Stehlík, J Senk

Acta Chir Orthop Traumatol Cech. 1989; 56(5):419-425

The authors present four-year surgical experience using Helal's oblique metatarsal subcapital osteotomy to manage metatarsalgy of various etiology. A total of 109 patients (131 feet) were operated on during the observance period. The amount of 79 patients (108 feet) were revised on the average 21 months after the surgery. According to Gainor's score excellent results were achieved in 76.9 per cent of cases, 3 patients were re-operated on for a relapsing preoperational condition. The indication for Helal's metatarsal osteotomy is the finding of metatarsalgy with reducible metatarsal capitula.

[Helal's metatarsal osteotomy].

Acta Chir Orthop Traumatol Cech. 1989; 56(5):426-435

At the Orthopaedic Clinic of the Institute for In-Service Training of Physicians and Pharmaceuts of the Teaching Hospital at Bulovka in Prague Helal's metatarsal osteotomy was performed between 1979-1987 in 54 patients for obstinate pain in the forefoot. Evaluated were 41 patients which underwent the operation minimum two years ago. The control group comprised 38 female and 3 male patients, the average age was 54 years. In 17 patients the operation was performed bilaterally. Thus in total we evaluated 58 osteotomies according to Helal. Excellent result was found out in 19 patients (46 per cent), good result in 20 patients (48 per cent). Only in 4 cases...

[Personal experience with Wolf's metatarsal osteotomy].

M Ambler

Acta Chir Orthop Traumatol Cech. 1989; 56(5):436-439

The author presents longterm experience with the surgical treatment of metatarsalgia by subcapital osteotomy. Operated on were 903 metatarsals in 281 patients. The operation brought relief in 96.5 per cent of cases. The article presents the surgical technique, indications for and complications of the method.

[Unusual complications of anticoagulation therapy].

V Vyskocil, J Pelnár, J Steiningerová

Acta Chir Orthop Traumatol Cech. 1989; 56(5):440-445

In the introduction to the work the authors deal with the problems of the prevention of flebotromboses in patients operated on in the area of proximal part of the femur. They analyze ways of physical and pharmacological prevention and point out the potential undesirable effects and unusual complications in the treatment by means of Heparin and Kumarin derivatives--and namely the toxoallergic reaction to Heparin and the necrosis of skin and subcutis in case of the application of Kumarin drugs. In Kumarin necrosis the etiology of the which has not been, unequivocally elucidated, yet, they present views on the causes of its origin and describe the course...

[Classification of deformities of the glenoid labrum in congenital hip dislocation].

A Sosna, S Popelka

Acta Chir Orthop Traumatol Cech. 1989; 56(5):446-456

The authors have developed their own classification of the deformities of labrum glenoidale in congenital hip dislocation. Open reposition was performed by the Ludloff procedure. The basic material for their work was the group of patients operated on at I. Orthopaedic Clinic of the Faculty of General Medicine of Charles University in Prague in the years 1970-1985. In the course of this period they operated on 78 hip joints in 70 children, out of which 8 operations were bilateral, the group comprised 17 boys and 53 girls, operation was performed on 30 right hip joints and 48 left ones. The age of children ranged from 5 to 23 months. The average age...

[The role of exogenous factors in the etiology of congenital hip dislocation: a socio-epidemiologic study].

J Drimal

Acta Chir Orthop Traumatol Cech. 1989; 56(5):457-464

The authors present in their work the results of the analysis of the relation between congenital dislocation of vertebral joints and social factors which they have found out in 120 children singled out of 9516 live-born children in the Martin district (Slovakia) in the period 1979-1983. The investigation of social factors has been based on the analysis of socioeconomic and social conditions of the Martin district which has no regional particularities. According to their results the share of exogenous factors in the origin and development of this disease is manifested more frequently in the first-borns (having the highest representation in the examined...
