[Clinical Wear Behaviour of UHMW Polyethylene Cups Paired with Metal and Ceramic Ball Heads in Comparison to Metal-on-Metal Pairings of Hip Joint Replacements.].

M Semlitsch, H G Willert

Acta Chir Orthop Traumatol Cech. 1996; 63(2):68-82

In the course of 30 years' hip endoprosthetics, a number of material combinations for the cups and balls of total hip prostheses have proven successful under clinical conditions. Favourably priced hip prostheses with polyethylene cups and metal balls are available for very old patients with a moderate range of activity. Polyethylene wear of 100-300 microm per year is to be expected with these models. Ceramic balls (aluminium oxide for diameters 32 and 28 mm and zirconium oxide for 22 mm) paired with polyethylene cups are recommended for patients with a life expectancy of 10 to 20 years, because the expected polyethylene wear rate with this material...

[Treatment of instability of the lumbar spine by glass-ceramic prostheses of the intervertebral disc.].

M Filip, P Veselský

Acta Chir Orthop Traumatol Cech. 1996; 63(2):83-87

The authors evaluated the short-term results of stabilization operations of the lumbar spine by means of a glass-ceramics replacement of the intervertebral disc in a group of 25 patients. Indication for operation was monosegmental instability or spondylolisthesis grade I in the lumbar spine with progressing clinical symptoms. In 20 patients stabilization was achieved merely by a pair of glass-ceramic endoprostheses, in five patients the stabilization operation was supplemented by transpedicular instrumentation. Twenty-two patients, now 3-12 months after operation are better. In three patients the preoperative complaints persist, in one female patient...

[Twenty Years Experience with Gardner's Coccygectomy.].

R Hart, K Rynda

Acta Chir Orthop Traumatol Cech. 1996; 63(2):88-90

The authors present their twenty-year experience with coccygectomy as described by Gardner in a group of 60 patients. The mean age was 36 years, the youngest patient was 11 years old and the oldest 63 years. The group was formed mostly by women (95 %). The authors evaluated in particular the subjective response to the operation, i. e. mitigation of pain, the etiology, persistence of complaints, period and type of ambulatory treatment and the postoperative course (i. e. healing of the surgical wound, type of after-treatment and convalescence period. In the described group of patients 53 reported complete regression of complaints, in seven patients the...

[Instabile thorax in polytraumatized patients: set for stabilization.].

J Michek, P Zelnícek, J Kubacák, J Vrastyák

Acta Chir Orthop Traumatol Cech. 1996; 63(2):91-94

Thoracic trauma represents 12,8 % of all trauma patients treated in author's workplace. Mortality was 12,7 %. Authors evaluated the contribution of new diagnostic methods, in particular CT examination with contrast and sonography, to determinate the indication of the early surgical treatment. From 1992 in the framework of the grant project the early surgical treatment of instable thorax was performed in 29 patients with polytrauma and serious associated thoracoabdominal trauma by the own set prepared in cooperation with the firm Medin. Authors determined indications for thorax stabilization prudently, and stated contemporary contraindications of this...

[Monitoring of the intracranial pressure in craniocerebral injuries.].

J Zelenák, M Hutan, K Kálig

Acta Chir Orthop Traumatol Cech. 1996; 63(2):95-97

The authors analyzed a group of 26 patients with serious craniocerebral injuries during a 20-month period, where the total mortality was 26 %. The majority of injuries was contracted during traffic accidents and the most frequent CT finding on admission was traumatic subarachnoidal haemorrhage and contused and haemorrhagic foci in the brain. As during craniocerebral injuries no direct relationship develops between impairment of consciousness and intracranial pressure the authors recommend continuous assessment of the intracranial pressure. It is important for prevention and treatment (medicamentous, ventilation regimen and nursing care) of intracranial...

[Hepatic injury.].

P Labas, M Huorka, L Lukác

Acta Chir Orthop Traumatol Cech. 1996; 63(2):98-101

Based on a critical review and analysis of results of surgical treatment of blunt liver injuries from 1983 to the present time the authors emphasize the importance of primary treatment of liver injuries. The foremost effort of the surgeon is reliable, aimed haemostasis during temporary short-term ischaemia of the liver by Pringle's manoeuvre or by a block of the suprahepatic cava resp. Pericentesis of the liver is not suitable for hepatic surgery. The second demand is systematic débridement of devitalized parts of the liver even if atypical resections must be made. In the group of patients where these two principles were respected, the number of complications...

[New regulations for the organization of the bone banks.].

M Richtr, D Pokorný, A Sosna

Acta Chir Orthop Traumatol Cech. 1996; 63(2):102-105

The authors summarized the basic rules for the organization of banks which are accepted applied worldwide. At the same time they present an account on experience assembled during the establishment of such a bank at the Orthopaedic clinic of the First Medical Faculty, Charles University. On the above findings the foresighted legislation on collection storage and administration of bone grafts is based. Key words: bone bank, bone graft.
