J Poul, M Svébis

Acta Chir Orthop Traumatol Cech. 2001; 68(5):289-293

PURPOSE OF THE STUDY: The aim of the retrospective study was to evaluate the results of 20 performed lengthenings of the humerus in children and adolescents.MATERIAL: Assessment involved totally 20 lengthening procedures having been done in 18 patients, twice as a repeated procedure, in the period 1983-1999. The indication was shortening of humerus approaching at least the amount of 50 millimeters. Proportion of boys and girls was 7/13. The shortening arouse on the base of pyogenic infection in 12, post-traumatically in 3, congenitally in 2 and in one case it was caused by a bone cyst expansion. Mean value of shortening was 83 millimeters. Mean...

[Duration of surgery in osteosynthesis of fractures of the trochanter].

J Bartonícek, P Dousa, R Kostál, F Svatos, J Skála

Acta Chir Orthop Traumatol Cech. 2001; 68(5):294-299

PURPOSE OF THE WORK: To analyze duration of surgery in individual types of internal fixation of fractures of the trochanteric massif and identify factors which have an impact on it.MATERIAL: Analysis covered a group of 137 patients treated with Ender nailing (EN), 314 patients by means of Dynamic Hip Screw (DHS), 74 patients by means of Gamma nail, 37 patients by means of Proximal Femoral Nail (PFN) and 13 patients by means of 130 degrees angled blade plate. The groups of patients included basicervical femoral neck fractures (29 cases), peritrochanteric and subtrochanteric fractures. Peritrochanteric fractures were evaluated according to Kyle classification,...

[Effect of ultrasonic shock waves on the bone-bone cement interface].

J Hach, A Benes, A B Hani, A Sosna, P Sunka

Acta Chir Orthop Traumatol Cech. 2001; 68(5):300-303

PURPOSE OF THE STUDY: Identification of the impact of ultrasound shock wave on the integration of bone cement in the bone and the examination of a potential application of this method in order to facilitate the extraction of cemented implants, mainly femoral component of total hip arthroplasty.MATERIAL: We used pig proximal femurs from which we made fragments involving approximately one third to one half of the profile of the bone and Palacos bone cement.METHOD: We made a groove in the cancellous bone, pressed bone cement with a wire loop in the cavity and let it harden. The samples were divided by random selection into two groups. Samples...

[The Pipkin fracture].

O Krempaský, T Knybel

Acta Chir Orthop Traumatol Cech. 2001; 68(5):304-310

PURPOSE OF THE STUDY: The authors present their experience in the treatment of fracture-dislocation of femoral head--the Pipkin fracture.MATERIAL: The group includes 11 patients treated in the period of 9 years (1991-2000). The average age was 46 years (range, 23-63 years). The average follow-up was 3.2 years (range, 6 months-9 years). According to the Pipkin classification four times we diagnosed Type 2, four times Type 3 (three times iatrogenic during closed reduction), three times Type 4. In 10 patients it was a case of a dashboard injury of drivers or passengers. In one patient it was industrial accident.METHODS: Ten patients were treated...

[Aprotinin (Antilysin Spofa)--its effect on decreasing hemorrhage in the postoperative period in hip arthroplasty].

K Cvachovec, H Sechovská, J Berousek, S Popelka, M Hladíková

Acta Chir Orthop Traumatol Cech. 2001; 68(5):311-314

PURPOSE OF THE STUDY: Aprotinin is a non-specific inhibitor of serine proteases with hemostyptic and hemostatic properties. The effect covers suppression of fibrinolysis and support of the role of thrombocytes in coagulation. In a prospective randomized study we verified whether the application of aprotinin (Antilysin Spofa, Czech Republic) in the dosage effective in cardiosurgical patients reduces blood loss and the need for blood transfusion for orthopaedic patients.MATERIAL: 42 patients indicated to the primary THA were randomly selected into the study and control groups. Excluded were allergic patients and those who used aprotinin before.METHODS:...

[Fractures of the sternum].

P Drác, P Manák

Acta Chir Orthop Traumatol Cech. 2001; 68(5):315-319

PURPOSE OF THE STUDY: Assessment of the authors' group of patients with a fracture of sternum and comparison with available literary findings.MATERIAL AND METHODS: In a group of 188 patients with a blunt injury of chest who were hospitalised in the Faculty Hospital in Olomouc in the period of 1996-1999 there were 7 cases with the diagnosis of the fracture of sternum. In this group of patients we observed the cause of injury, occurrence of associated injuries, the potential of diagnostic methods, method of treatment and duration of hospitalization.RESULTS: Mostly they were patients with an isolated fracture of the sternum or with an associated...

[A rare case of extensive bilateral polyethylene granuloma after knee replacement].

P Vavrík, S Popelka, J Vírava

Acta Chir Orthop Traumatol Cech. 2001; 68(5):320-323

The authors present a case of bilateral loosening of total knee arthroplasty as a result of polyethylene (PE) wear. Five and seven years after TKA the patient developed a polyethylene granuloma leading to extensive bone defects under the implant. Finally it resulted in pathological fracture of medial condyle of tibia. A revision PFC stabilized prosthesis was used for reimplantation. Bone defects were filled in by bone grafts from the bone bank. Authors point out the issues of PE wear. In the discussion they list various factors (time, indication, material, design and the factor of individual response of the organism) which may play an important role...

[Os scaphoideum--functional and clinical anatomy].

I Dylevský, V Mrzena

Acta Chir Orthop Traumatol Cech. 2001; 68(5):327-330

1. Scaphoid bone is the largest and clinically most significant bone in the proximal row of the carpal bones. It consists of three sections: proximal and distal pole and scaphoid waist. Extension and radial duction of the hand results in overloading of distal pole of scaphoid and its waist. 2. Nutrient arteries (from radial artery) enter the bone predominantly from the dorsal surface (75%). Functional intraosseous anastomoses do not exist. In 33% of cases proximal scaphoid has no separate nutrient arteries. 3. Scaphoid bone develops from two centres; however, two separate ossification nuclei are quite rare. Non-union of both centres during the early...
