[Giant cell tumor--osteoclastoma: part II].

Acta Chir Orthop Traumatol Cech. 2001; 68(3):141-147

Authors present current views on the comprehensive diagnostics, treatment and prognosis of giant cell tumours. They include an exact algorithm of diagnostics necessary for a timely treatment. They describe an often unexpected behaviour of these tumours which is frequently active and aggressive, to a small extent these tumours show the tendency to become malignant. The treatment prefers curretage, antibiotic irrigation and filling in with bone cement. In case of recurrence and an extensive process, block resection and replacement by an individual implant, in hardly accessible locations (spine, sacrum, pelvis) or radiotherapy is recommended.

[Personal experience with the Wagner revision stem in hip joint reoperations].

O Cech, J Stehlík, M Krbec, V Vrecion

Acta Chir Orthop Traumatol Cech. 2001; 68(3):148-161

PURPOSE OF THE STUDY: Since 1993 we have been using the Wagner revision stem, initially in the length of 265 mm and 305 mm and later also the short stem of 190 mm and 225 mm, for revision surgery with the destruction of proximal femur. This technique provided for primary fixation of the stem in the unaffected femoral bone and creates prerequisites for the bone regeneration and bone formation of the destructed host bone by the loosened implant in the metaphysis and proximal part of diaphysis.MATERIAL AND METHODS: In the period of 1993-1998 we operated on and followed a group of 35 patients (18 men and 17 women), average age 69 years (age range,...

[Reconstruction of the acetabulum during replacement of the aseptically loosened polyethylene cup].

K Koudela, T Malotín

Acta Chir Orthop Traumatol Cech. 2001; 68(3):162-167

THE PURPOSE OF THE STUDY: The aim of the study was to verify the method after Slooff in our modification, i.e. "a cemented cup--cancellous bone grafts--a metal net" for the revision surgery of aseptic loosening of cemented polyethylene acetabular cup in combined defects of acetabulum.MATERIAL: The followed-up group of 52 patients (36 women and 16 men), average age of 65 years (age range, 50-81 years) with aseptic loosened cemented polyethylene Poldi cups included 52 operated on hip joints. The average interval between the primary implantation and the revision surgery was 9 years (2-21 years).METHOD: We reconstructed acetabulum with combined...

[Effect of fibrin on osseointegration of bioactive glass-ceramic materials--experimental study].

K Urban, C Povýsil, S Spelda

Acta Chir Orthop Traumatol Cech. 2001; 68(3):168-175

PURPOSE OF THE STUDY: The aim of the experimental study is to find out how fibrin influences the speed of osteiontegration of bioactive glass-ceramic materials BAS-O, BAS-HA, BAS-R (LASAK Prague, Czech Republic) and how it influences the response of live tissue at the implant-bone interface in the interval of 1-8 weeks.MATERIAL: Dense materials BAS-0 (glass-ceramics), BAS-HA (hydroxyapatite) and BAS-R (beta tricalcium phosphate) in the form of 0.6-1 mm granules were implanted in artificially created defects in tibia of an experimental animal with the addition of 0.1 ml of fibrin adhesive system Beriplast. Control implantation was performed with...

[Prevention of development of hip joint instability in patients with the spastic form of juvenile cerebral palsy].

R Sindelárová, J Poul

Acta Chir Orthop Traumatol Cech. 2001; 68(3):176-183

PURPOSE OF THE STUDY: How effective are the hip adductors and flexors tenotomies for the correction of unstable hip joint in cerebral palsy?MATERIAL: The study included 45 children with contractures of the hip adductors and flexors and hip subluxations due to spastic cerebral palsy. Thirty three of them were boys and 12 were girls. Their ages ranged from 2 to 13 years. Preoperative and postoperative roentgenograms of 82 hip joints were investigated.METHODS: Open tenotomies of m. adductor longus and brevis, m. gracilis, m. rectus femoris and m. psoas major. The immobilisation by POP casts lasted for 6 weeks. Abduction and extension bracing followed...

[Indications for the cementless Zweymuller Bicon cup in acetabular fractures].

P Hajný, P Dungl, V Stědrý, M Biegel

Acta Chir Orthop Traumatol Cech. 2001; 68(3):184-187

PURPOSE OF THE STUDY: The aim of the study is an assessment of short-term results after the implantation of cementless Zweymüller Bicon cup in patients with a complicated anatomy after acetabular fractures.MATERIAL: The group of 10 patients indicated for Zweymüller cementless THR in post-traumatic osteoarthritis after acetabular fracture was selected of the total number of 703 primary implantations performed in 1998 and 1999 at the authors' Orthopaedic Department. The group includes patients treated conservatively as well as by means of open reduction and fixation.METHODS: For the evaluation we used Harris Hip Score and radiographic assessment...

[Tension cerclage using scews--a forgotten technique?].

J Bartonícek, D Jehlicka, J Stulík

Acta Chir Orthop Traumatol Cech. 2001; 68(3):188-191

Authors deal with the screw-wire technique described by Brunner and B. G. Weber in 1981. The principle of the technique consists in passing a wire loop around the heads of divergently driven screws. After tightening the screws the wire loop is put under tension which results in interfragmental compression. Mostly used for this purpose are 4.5 mm cortical screws but, if need be, any screw from a standard or small set of instruments is applicable. This type of fixation they use mainly for acetabulum fractures, diastasis of symphysis or for the stabilization of knee osteotomies.
