Acta Chir Orthop Traumatol Cech. 2003; 70(1):6-16

PURPOSE OF THE STUDY: The experience obtained during revision surgery and findings of polyethylene granulomas in surrounding tissues of replacement as well as marked differences in the viability of implants resulted in the study of polyethylene disease and its basic mechanisms producing the development of osteoaggressive granulomas. We investigated the morphology of particles and their number in tissues surrounding the implant. The aim of our study was to develop a method for the detection of polyethylene particles in tissues, to identify different types of wear and to assess factors that may influence the viability of joint arthroplasty in general.MATERIAL:...

[Two-stage reimplantation using spacers--the method of choice in treatment of hip joint prosthesis-related infections. Comparison with methods used from 1979 to 1998].

Acta Chir Orthop Traumatol Cech. 2003; 70(1):17-24

PURPOSE OF THE STUDY: Several therapies are available for the treatment of deep infection in total hip arthroplasty but none is completely successful; there is no consensus on an optimal method. The aim of this study was to evaluate the treatment used in our institution and its outcomes over the last 20 years. In each method, the success of treatment was evaluated in terms of both infection control and restoration of function in the treated joint.MATERIAL: A total of 172 patients with infected total hip replacements were treated at the First Orthopedic Clinic of the First Faculty of Medicine, Charles University, Prague, between 1979 and 1998. Our...

[Restoration of elbow joint flexion by transfer of the pectoralis major muscle in patients with arthrogryposis multiplex congenita. Part II. Results of electromyographic and histologic examinations].

J Chomiak, P Dungl, M Grim

Acta Chir Orthop Traumatol Cech. 2003; 70(1):25-30

PURPOSE OF THE STUDY: In the framework of a prospective study on transposition of the m. pectoralis major according to Clark in patients with type I arthrogryposis multiplex congenita, electromyography was carried out in order to determine pre-operative states of the elbow joint flexors and m. pectoralis major and then the post-operative electric activity of a transposed muscle and to correlate changes with clinical findings. Histological examination was performed to reveal changes in muscle morphology and to complete a comprehensive assessment of muscle transposition.MATERIAL AND METHODS: Electromyography was carried out on nine upper limbs of...

[Osteosynthesis of proximal femoral fractures using short proximal femoral nails].

T Pavelka, J Kortus, M Linhart

Acta Chir Orthop Traumatol Cech. 2003; 70(1):31-38

PURPOSE OF THE STUDY: A group of 147 patients with proximal femoral fractures treated with the use of the proximal femoral nail, manufactured by the Synthes company, in the period between October 1997 and June 2001 were retrospectively evaluated.MATERIAL: The group of 147 patients whose average age was 69 years consisted of 59 men (average age, 59 years) and 88 women (average age, 75 years). The most frequent fracture occurring in 54% of the patients was an unstable pertrochanteric fracture (Kyle III); persubtrochanteric and subtrochanteric fractures were treated in 27% and 19% of the patients, respectively.METHODS: In 1997, a new implant,...

[Initial experience with implantation of the cemented Beznoska/S.V.L. total knee joint endoprosthesis].

R Kubes, P Dungl, A Podskubka, V Stědrý

Acta Chir Orthop Traumatol Cech. 2003; 70(1):39-46

PURPOSE OF THE STUDY: The authors present the results of their first trial of a new, Beznoska/S. V. L. type, knee prosthesis in order to introduce it to a broad orthopedic public.MATERIAL: Clinical and radiological evaluation was carried out on 34 knee prostheses implanted in 31 patients between September 1997 and October 1999. The average patient age at the time of surgery was 71.3 years and the average interval between surgery and assessment was 22.4 months (range 6 to 31 months). All patients underwent implantation due to primary or secondary gonarthosis. A brief description of the implant and the instrumentation and used surgical technique...

[Case report of extensive metallosis in extra-articular tissues after unicompartmental knee joint replacement].

R Hart, M Janecek, B Bucek

Acta Chir Orthop Traumatol Cech. 2003; 70(1):47-50

The authors present a case of extensive metallosis of the knee joint resulting from the secondary abrasive wear of components of a unicompartmental alloplasty. Eight years after medial condyle replacement, an eighty-year-old patient presented with a break of the femoral component. This resulted in a rapid wear of tibial polyethylene and the development of secondary friction between two metal surfaces. The generation of a large number of metal particles produced an increase in the actual metal surface. This extensive articular metallosis affected not only intra-articular but also extraarticular tissues and the subchondral bone. Histological examination...

[Current views on diagnosis of osteoarticular tuberculosis].

M Netval, A Sosna, T Hudec

Acta Chir Orthop Traumatol Cech. 2003; 70(1):51-55

This paper presents current methods used in the diagnosis of osteoarticular tuberculosis in the Czech Republic. It draws attention to difficulties and errors associated with the diagnosis of this disease. The aim of this study is to provide a comprehensive review of relevant diagnostic methods, from medical history to imaging techniques. A misdiagnosis and/or a late establishment of the diagnosis, which may result in inadequate primary therapy, prolong both the time needed for complete treatment and the duration of absenteeism. These may eventually have negative economic and social implications.
