[Importance of vascular and mechanical factors for bone healing.].
J Hert
Acta Chir Orthop Traumatol Cech. 1992; 59(5):259-267
The author submits a brief account of contemporary views on the importance of vascular and mechanical factors for healing of bones. Damage of the vascularization after fractures when using conservative treatment and intramedullary and external fixation, does not influence bone healing in a substantial way. In those instances the bone heals by forming a callus with newly formed ample vascularization. On the other hand, in case of osteosynthesis, using a splint with perfect stabilization, the bone heals very slowly by a process of direct healing by haver remodelling. The period of healing is proportional to the extent of bone necrosis. Therefore biological...
[Technique of osteosynthesis in replantations of the upper extremity.].
J Stehlík, M Tvrdek
Acta Chir Orthop Traumatol Cech. 1992; 59(5):268-271
The authors report on their experience with osteosynthesis in replantation of the upper extremities in 21 patients. For stable connection of the two parts they use the method of external osteosynthesis which enables the plastic surgeon to perform undisturbed surgery with access of the microscope along the entire circumference of the extremity. The authors emphasize the importance of correct indication for replantation, the shortening of both ends of the bones and early extensive fasciotomy performed in time. The apparatus used for external osteosynthesis was the POLDI type which proved very useful and met all requirements for stable fixation during...
[Arthrodesis of the ankle by a tibiometatarsal frame.].
M Richtr, A Sosna, M Rysavý
Acta Chir Orthop Traumatol Cech. 1992; 59(5):272-279
The authors submit a biomechanical analysis of the most frequently used methods of stabilization of arthrodesis of the ankle joint. From the biomechanical aspect they describe the foot as a two-arm lever; on its shorter arm (rotation centre of the talus insertion of the Achilles tendon) acts the muscular force, i. e. plantiflexion with a value of 640 kg, and on its longer arm (rotation centre of the talus - forefoot) acts the muscular force in the sense of dorsiflexion with a value of 140 kg. These forces in particular in the sense of plantiflexion act after fusion of the ankle against the stability of the arthrodesis. The relatively small success...
[Long-term Results of Arthrodesis of the Talocrural Joint.].
M Richtr, A Sosna, M Rysavý
Acta Chir Orthop Traumatol Cech. 1992; 59(5):280-288
The authors evaluate a group of 19 arthrodeses of the talocrural joint in 16 patients after a mean interval of 6 years and three months following arthrodesis (operation). They demonstrate that the hitherto used method of evaluation of the position of the foot after arthrodesis of the ankle - measurement of the tibiotalar angle, is insufficient and does not record the changes in function and shape distally from Chopart's joint, e. g. pes cavus. Some deformities of the foot can lead to an entirely afunctional arthrodesis even when from the theoretical aspect the tibio-talar angle of arthrodesis is correct. The evaluation from the lateral radiograph only...
[Treatment of Post-traumatic Deformities of the Foot.].
Z Rozkydal, Z Smíd, M Kovanda, M Sklenský
Acta Chir Orthop Traumatol Cech. 1992; 59(5):289-293
The authors evaluate their results of corrective surgery of the foot in conditions after injury. In 1965 - 1985 they used classical resection "sub talo" in 22 patients with 14 good, 4 satisfactory and 4 poor results. Poor results were recorded where arthritis of the talocrural joint, necrosis of the talus, pseudoarthrosis, residual deformity or instability developed. The authors evaluate also 5 patients treated by a new technique (so-called dowel graft technique). In all patients satisfactory results were achieved. In osteotomies of the tarsus they achieved a better cosmetic effect after operation when using Japase's method. Arthrodesis of Lisfrank's...
[Removal of infected alloplasty of the hip joint.].
J Kubice, J Pilnácek
Acta Chir Orthop Traumatol Cech. 1992; 59(5):294-296
In 1979 - 1989 at the Orthopaedic Clinic of the Institute for Postgraduate Medical Training a total of 62 alloplasties of the hip joint were removed. On account of infection 44 endoprostheses were removed, the remainder for other reasons. The authors examined a total of 19 patients who attended check-up examinations. Evaluation of the function of the hip joint after removal of the endoprosthesis was made by Harris' method. Evaluation of the painfulness of the hip joint revealed that 6 patients were free from pain, 4 patients reported only slight pain after burdening. The remaining patients suffered from pain which had to be mitigated by analgetics,...
[Follow-up of Patients Treated by Sliding Compressive Screws on Account of Fractures of the Head ot the Femur.].
J Palarcík, J Krahulová
Acta Chir Orthop Traumatol Cech. 1992; 59(5):297-301
The authors submit an analysis of a patient group treated in 1986 to 1987 by synthesis, using a dynamic sliding compressive screw produced in POLDI Kladno for fractures of the neck of the femur after an interval of cca 4, 5 years (interval 4-5 years) following synthesis. Apreliminary reports after cca 6.5 months following operation was submitted in 1988. From the original group of 26 operated patients four patients died during the follow-up period, seven were lost from the follow, three were reoperated because of early failure of the synthesis. An account of all three patients was presented in the previous communication. Another tree patients were...
[The Influence of the Implanted Material (Glass Carbon) for the Proliferation of the Cell's.].
V Pesáková, K Balík, M Adam
Acta Chir Orthop Traumatol Cech. 1992; 59(5):302-304
The authors have examined the influence of the implanted material (glass carbon) for the proliferation of human embryonal fibroblasts. It has been found that the tested material did not inhibit the cell's proliferation and it performed a good biocompatibility. Key words: fibroblasts, implanted material, glass carbon.
[Heterotopic ossification from the view of an orthopaedist and anesthesiologist.].
J Knezek, J Cyprich, B Limberk
Acta Chir Orthop Traumatol Cech. 1992; 59(5):305-310
The authors draw attention to the possible development of heterotopic ossifications in patients treated at resuscitation departments on account of prolonged loss of consciousness and in orthopaedic and traumatological departments after operations of the locomotor apparatus. They reflect on the aetiology, pathogenesis of this unpleasant complication. In the conclusion they draw attention to possible prevention and treatment by non-steroid antirheumatic drugs, X-ray therapy in small doses and surgical treatment. Key words: heterotopic ossification, paraarticular ossification.

M Houdek, P Nádvorník, J Kolarík, R Ditmar, P Hlustík
Acta Chir Orthop Traumatol Cech. 1992; 59(5):311-313
The authors describe successful use of an whole-body stereotactic apparatus for collection of pathological tissue samples from the vertebral body L2. Key words: whole-body aiming apparatus, stereotactic biopsy, vertebral body.
