Acta Chir Orthop Traumatol Cech. 2006; 73(4):237-242 | DOI: 10.55095/achot2006/034  

PURPOSE OF THE STUDYVarious techniques are used for detection of pathogens in musculoskeletal infection. These methods differ with respect to reliability and ease of handling. A prospective study was performed to evaluate the efficacy of three intraoperative techniques.MATERIAL AND METHODSIn 20 cases (18 patients) with clinically confirmed acute musculoskeletal infections, intraoperative collected swab samples, tissue samples and fluid samples injected into standard blood culture vials were used for microbiological diagnosis. Identification of bacteria, time necessary for detection and ease of handling during surgery was evaluated.RESULTSIn...

PURPOSE OF THE STUDYAseptic loosening of implants is the main complication affecting the longevity of joint prostheses. The highest proportion of loosening occurs due to osteolysis produced by the presence of ultra-high molecular weight polyethylene (UHMWPE) wear particles smaller than 1 μm. These can be identified by microscopic, spectroscopic or light-scattering methods. Here we describe our method for counting wear particles, based on the principle of light scattering.MATERIAL AND METHODSBetween 2002 and 2004, we collected samples of polyethylene granuloma in 19 patients who underwent revision total hip arthroplasty (THA) for aseptic...

Acta Chir Orthop Traumatol Cech. 2006; 73(4):251-263 | DOI: 10.55095/achot2006/036  

PURPOSE OF THE STUDYThe treatment of chondral defects by transplantation of autologous chondrocytes has recently shown further development. Various biomaterials are used as carriers facilitating attachment and even distribution of chondrocytes in the defect. Since 2003 Hyalograft C, hyaluronan-based scaffolds, has been used, in a clinical study, for implantation of autologous chondrocytes in the treatment of deep chondral lesions of the knee at our department.MATERIALEight patients (7 men and 1 woman; average age, 31 years) followed up for at least 9 months were evaluated. The lesions with an average size of 3.9 cm² were localized...

Complex Injuries of the Shoulder - Floating ShoulderOriginal papers

W. KÖSTLER, P. C. STROHM, O. HAUSCHILD, N. P. SÜDKAMP

Acta Chir Orthop Traumatol Cech. 2006; 73(4):264-267 | DOI: 10.55095/achot2006/037  

Complex injuries of the shoulder are comparatively rare. Within the field of complex shoulder injuries this article particularly deals with the diagnosis and therapy of the "floating shoulder injury" as a review article. This term describes a discontinuation of the osseus and soft tissue suspension of the upper extremity from the axial skeleton. By literature review and involvement of recent biomechanical studies this article will show the injury patterns that lead to instability of the shoulder girdle and the therapeutic to be employed in respective cases.

Acta Chir Orthop Traumatol Cech. 2006; 73(4):268-274 | DOI: 10.55095/achot2006/038  

PURPOSE OF THE STUDYA group of 49 patients treated by total hip arthroplasty after previous surgery for an acetabular fracture are evaluated in this retrospective study.MATERIALIn the period from 1997 to 2004, 49 patients, 35 men and 14 women, with posttraumatic arthritis following acetabular fracture were treated in our department. The average age was 42 years, with 67 % of the patients being younger than 40 years. The average follow-up was 42 montsh (range, 18 to 92). The acetabular fractures evaluated by the AO classification included type A1 in 17 patients, type A2 in seven, type B1 in nine, type B2 in six, type B3 in seven, type C1...

Early Primary Total Hip Arthroplasty for Acetabular Fractures in Elderly PatientsOriginal papers

Acta Chir Orthop Traumatol Cech. 2006; 73(4):275-282 | DOI: 10.55095/achot2006/039  

PURPOSE OF THE STUDYThe aim of this pilot study was to evaluate the clinical and functional outcomes of total hip arthroplasty (THA) in patients with acetabular fractures due to a low-energy injury. Acute primary THA included an antiprotrusion cage and autologous bone grafting of the acetabulum. This prospective study was carried out between 1998 and 2004.MATERIALTen patients, of whom six were men, (average age, 71 years; range, 60 to 83 years) with acetabular fractures were treated by THA. Two patients had type A2, two had type B1, three had type B2 and three had type B3 fractures, as assessed by the AO classification. X-ray showed osteoporosis...

Cementless Ceramic-on-Ceramic Total Hip SystemOriginal papers

Acta Chir Orthop Traumatol Cech. 2006; 73(4):283-286 | DOI: 10.55095/achot2006/040  

PURPOSE OF THE STUDYThis is an experimental and clinical study on the use of cementless, ceramic-on-ceramic total hip arthroplasty (THA).MATERIAL AND METHODSIn the experimental part, the authors constructed, by means of mathematical analysis of finite elements, surface tension standards for the ceramic liner at various angles of cup inclination, and identified potentials for destruction of the liner. In the clinical trial, they evaluated the outcomes in 50 patients, out of the 249 implanted prostheses, at five-year follow-up.RESULTSThe experiment showed that a slightly steeper inclination the cup provided physical conditions for...

Principles and Clinical Application of the Locking Compression Plate (LCP)Current concepts review

P. NIEMEYER, N. P. SÜDKAMP

Acta Chir Orthop Traumatol Cech. 2006; 73(4):221-228 | DOI: 10.55095/achot2006/032  

The principle of the locking compression plate (LCP) is represented by the combination of two completely different anchorage technologies and two opposed principles of osteosynthesis in one implant it combines the principles of conventional plate osteosynthesis for direct anatomical reduction with those of bridging plate osteosynthesis. Since the LCP can be used as a conventional plate using only dynamic compression, as a pure internal fixator using locking head screws, or as both combined, it provides the surgeon with multiple variations. Nevertheless, these new possibilities mean that preoperative planning and an understanding of the different biomechanical...

Current Strategies for Prevention of Prosthetic Joint InfectionCurrent concepts review

J. GALLO, I. LANDOR, P. VAVŘÍK

Acta Chir Orthop Traumatol Cech. 2006; 73(4):229-236 | DOI: 10.55095/achot2006/033  

Deep sepsis still remains the second most common cause of prosthetic joint failure despite its overall incidence is decreasing. It can be defined as a bacterial growth and replication on the prosthetic joint surface resulting in periprosthetic tissue damage and prosthesis loosening. The implants are colonized by airborne-, skin-, tool-, and/ or surgeon-related bacteria during surgery even though majority of procedures are performed under strictly respected conditions nowadays. After the insertion of the prosthesis into the human body the race between bacteria and host cells begins on what will colonize the prosthetic surface first. If the bacteria...
