Acta Chir Orthop Traumatol Cech. 2014; 81(1):33-39 | DOI: 10.55095/achot2014/003 
PURPOSE OF THE STUDYEach method of sterilisation has some effect on the structure and properties of UHMWPE and thus also on joint replacement longevity. This study was designed to compare, using objective methods of measurement, several kinds of sterilisation and to recommend the one which has the best prospect for making joint replacements last longer.MATERIAL AND METHODSTwo groups of UHMWPE samples were tested. Group 1 included virgin GUR 1020 polyethylene, non-modified and non-sterilised (Meditech, Germany). Group 2 comprised of three sets of samples sterilised with formaldehyde, gamma irradiation and ethylene oxide, respectively. In...

Acta Chir Orthop Traumatol Cech. 2014; 81(1):40-50 | DOI: 10.55095/achot2014/004
PURPOSE OF THE STUDYThe aim of the study is to present a comparison of short-term results of double- versus single-bundle anatomical reconstruction of the anterior cruciate ligament (ACL) using hamstring endons and their fixation with absorbable interference screws.MATERIAL AND METHODSA total of 110 patients with an isolated ACL lesion and the healthy contralateral knee who met the indication criteria for ACL double bundle reconstruction (TISL, 14 mm; ICNW, 12 mm) were intra-operatively allocated at random to either double-bundle group (DB, n=55) or single-bundle group (SB, n=55). At 12 months after surgery, 97 patients (DB group, n=49;...

Acta Chir Orthop Traumatol Cech. 2014; 81(1):51-56 | DOI: 10.55095/achot2014/005
PURPOSE OF THE STUDYShoulder instability adversely affects the quality of life and restricts the functional capacity of the upper extremity involved. Today stabilisation surgery is almost always performed arthroscopically. The aim of this study was to present our experience with arthroscopic stabilisation of the shoulder and to identify risk factors responsible for its failure.MATERIAL AND METHODSThe group of 110 patients with recurrent anterior dislocation of the shoulder, who were treated between January 2007 and December 2010, consisted of 19 women and 91 men with an average age of 27 years (range, 14 to 56) at the time of surgery. Patients...

Acta Chir Orthop Traumatol Cech. 2014; 81(1):57-62 | DOI: 10.55095/achot2014/006
PURPOSE OF THE STUDYThe aim of the study was to retrospectively evaluate the treatment outcomes of displaced supracondylar humerus fractures, including potential complications, in children treated at the Department of Paediatric General Surgery, Orthopaedics and Trauma Surgery of the Faculty of Medicine in Brno between 2000 and 2011.MATERIAL AND METHODSThe study comprised 564 children, 321 (57%) boys and 243 (43%) girls, who were allocated to two groups according to the method of primary treatment. The average age at the time of injury was 6.8 years (range, 1 to 16). In group 1, all 499 patients were indicated for primary closed reduction...

Acta Chir Orthop Traumatol Cech. 2014; 81(1):63-69 | DOI: 10.55095/achot2014/007
PURPOSE OF THE STUDYThe aim of the study was to assess the average length of a proximal and a distal incision, to verify the location of the axillary nerve and to identify risk factors for nerve injury during minimally invasive plate osteosynthesis.MATERIAL AND METHODSDuring cadaver sutdy a total of 24 implantations using the Philos angular stable plate were performed from the minimally invasive anterolateral approach. A five-hole plate inserted with the aid of new Philos aiming device was used in all cases. The plate was fixed with four screws proximally and with three screws to the diaphysis. After implantation either of the incisions...

Acta Chir Orthop Traumatol Cech. 2014; 81(1):70-76 | DOI: 10.55095/achot2014/008
PURPOSE OF THE STUDYThe aim of the study was to evaluate the clinical and radiographic results of total hip arthroplasty (THA) with the Metha short hip stem and their comparison with the outcomes of THA using a conventional cementless stem.MATERIAL AND METHODSA total of 30 Metha stems and 30 standard Biocontact stems implanted in the period from 2007 to 2012 were evaluated.The Metha patient group comprised 22 women and six men, with the mean age of 58.9±SD 8.7 years (43-75), mean height of 164.2±6.3 cm (156-178), mean body mass of 68.2±12 (48-91) and mean BMI of 25±3.9 (19-32). The Biocontact group included...

Defining reproducible criteria for lower extremity salvage following severe high-energy trauma continues to be one of the most challenging and controversially discussed fields in orthopaedic surgery. At present, however, the difficult performance, limited availability and number of valid reconstructive options for complex injury types, i. e. simultaneous osteoligamentous trauma with neurovascular lesions and severe soft tissue defects ("composite/compound multilayer defects") represent the decisive prognostic injury components triggering and determining the fate of the limb. Consequently, due to the complex injury pattern of the extremity and the overall...
Non-Union in Forearm FracturesCurrent concepts review

Acta Chir Orthop Traumatol Cech. 2014; 81(1):22-32 | DOI: 10.55095/achot2014/002
Non-union in forearm fractures is an uncommon but complex problem. This is especially given the unique anatomical structure and function of the forearm, making treatment distinctly different to that of other long bone fractures. Anatomical restoration of length, alignment, rotation and the radial bow maintains the optimal stabilising effects of the forearm muscles and interosseous membrane, as well as maximising the range of movement, particularly pronation and supination.Contemporary plate osteosynthesis using variations of the dynamic compression plate (DCP) developed by the AO group combined with established techniques of internal fixation have...
