PURPOSE OF THE STUDYFor an orthopedic surgeon it is difficult or even impossible to estimate the real quality of ultrahigh molecular weight polyethylene (UHMWPE) liners that are used in the total joint replacements (TJR) just on the basis of information given by the manufacturers. At the same time, the quality of the UHMWPE liner can impact strongly on the total lifespan of the implanted TJR. This work aims at independent, objective comparison of properties of the UHMWPE liners for total hip replacements (THR), which are most frequently used in the Czech Republic.MATERIAL AND METHODSWe analyzed seventeen most frequently implanted UHMWPE...

PURPOSE OF THE STUDYNano-structuring and nano-silver have been extensively studied for improving the antibacterial ability of implants due to their powerful antibacterial activity; however, there is no clinical application as yet. The aim of the study was to determine the antibacterial, antiadhesive and cytotoxic features of Ti6Al4V modified with nano-texturing and silver nano-particles.MATERIAL AND METHODSThe nanoparticles were applied on polished and nano-textured Ti6Al4V using sonoreduction. The surface topography, roughness, friction coefficients, hardness and elastic modulus values for prepared top layers were established. The materials...

Acta Chir Orthop Traumatol Cech. 2019; 86(2):118-123 | DOI: 10.55095/achot2019/016  

PURPOSE OF THE STUDYTo evaluate the efficacy of the systemic administration of two doses of tranexamic acid (TXA) in total knee (TKA) and hip arthroplasty (THA).MATERIAL AND METHODSThe study evaluated a total of 295 patients who underwent total knee and hip arthroplasty for osteoarthritis, prospectively followed up were the patients who had been administered the tranexamic acid (TXA), and this group was subsequently compared against the cohort - control group. Our evaluation was focused on perioperative and postoperative period. The amount of blood loss was monitored during the surgery as well as postoperatively. Moreover, the frequency...

Acta Chir Orthop Traumatol Cech. 2019; 86(2):124-130 | DOI: 10.55095/achot2019/017  

PURPOSE OF THE STUDYThe calcaneal bone is affected in 2% of body fractures. Because of its major influence to walking stability with its permanent consequences affecting both daily living and work activities, huge effort is expended on suitable treatment of these fractures. Many studies have focused on surgical treatment of calcaneal fractures or on comparing operative and non-operative treatment. The aim of this retrospective study is to investigate stability of different type of osteosynthesis.MATERIAL AND METHODSThis study involves 119 men and 24 women aged 20 to 84 years who were in the period from 2011 to 2015 surgically treated...

Acta Chir Orthop Traumatol Cech. 2019; 86(2):131-135 | DOI: 10.55095/achot2019/018  

PURPOSE OF THE STUDYAcromioclavicular joint dislocations (AC) represent one of the most frequent injury to the shoulder gridle. Low grade injuries type Rockwood I-II are treated non-operatively. Whereas high grade injuries type Rockwood III-VI are usually treated operatively. At present a wide spectrum of surgical techniques is used: Bosworth screw, hook plate, pinning and tension banding, PDS-sling. In our study the pinning and tension banding technique and the modified orthocord sling technique were compared. The goal of this study was to determine whether there are any clinical and radiological differences between these two techniques.MATERIAL...

Hinged Elbow External Fixation for Severe Elbow StiffnessOriginal papers

M. FERANEC, R. HART, T. KOZÁK, M. KOMZÁK

Acta Chir Orthop Traumatol Cech. 2019; 86(2):136-140 | DOI: 10.55095/achot2019/019  

PURPOSE OF THE STUDYThe elbow is a highly constrained synovial hinge joint that frequently becomes stiff after injury. Grade 4 elbow stiffness (ankylosis) is a strongly limiting factor in the patient s daily activities and is difficult to treat. Hinged external fixation of the elbow provides the advantages of static fixation with the benefits of continued motion of the joint. The goal of our study was to assess the improvement in the range of motion of the elbow after surgical arthrolysis using a posterior extensile approach to the joint with or without using external fixation.MATERIAL AND METHODSSixteen patients aged between 19 and 46...

PURPOSE OF THE STUDYThe purpose of the study was to assess two therapeutic procedures of temporary fixation of displaced ankle fractures, namely the plaster fixation or Kirschner wire (KW) transfixation via the sole of the foot.MATERIAL AND METHODSGroup of patientsThe randomised prospective study conducted in the period 02/2016-02/2017 compared two methods of temporary fixation of displaced ankle fractures. In total, 38 patients were included in the study (18 patients treated with plaster fixation, 20 patients treated with KW).MethodsDuring the randomisation (by envelopes, drawing of lots by the patient), in one group of patients,...

Acta Chir Orthop Traumatol Cech. 2019; 86(2):147-152 | DOI: 10.55095/achot2019/021  

PURPOSE OF THE STUDYThe standard procedure in treating distal humerus fractures is the open reduction internal fixation (ORIF). The surgical approach is still a matter of discussion. The submitted study focuses on comparing the conventional approach with olecranon osteotomy and the paratricipital approach.MATERIAL AND METHODSSince January 2015 a total of 18 patients have been operated on, who met the inclusion criteria of the study on type C distal humerus fracture without the use of olecranon osteotomy. This group of patients was subsequently compared with a control group of patients in whom the olecranon osteotomy was performed in the...

Acetabular Cup Positioning during Total Hip Replacement in Osteoarthritis Secondary to Developmental Dysplasia of the Hip - a Review of the LiteratureCurrent concepts review

L. ZHANG, X. LU

Acta Chir Orthop Traumatol Cech. 2019; 86(2):93-100 | DOI: 10.55095/achot2019/013  

Various surgical treatments for osteoarthritis (OA) secondary to hip dysplasia have been reported in the literature. According to the position of the arthroplasty cup, generally they could be divided into two groups: the primary rotational center (PRC) group and the high hip center (HHC) group. Some surgeons prefer the HHC technique. Without doubt it is less demanding, but several concerns exist against the long-term stability. When restoring the PRC, since the dysplastic acetabulum is usually shallower and underdeveloped, bone grafts or other biosynthetic materials are usually needed for the ideal fixation. The source of grafts is quite wide. For...

Acta Chir Orthop Traumatol Cech. 2019; 86(2):153-155 | DOI: 10.55095/achot2019/022  

The submitted case study concerns a 36-year-old patient with a ladder fall injury, who suffered a comminuted right pilon fracture type C3 according to the AO classification. The primary treatment consisted in fixing the fracture with an ankle spanning external fixation and subsequent internal osteosynthesis after the recovery of soft tissues. At four weeks, an infection with fistula developed on the anterior face of the distal tibia. The patient was repeatedly treated with excochleation of suspected focus of osteomyelitis, soft tissue drainage by VAC system, application of antibiotics based on the microbial agent susceptibility. Despite the aforementioned...

Bilateral Distal Tibial Stress Fracture in a TriathleteCase report

Acta Chir Orthop Traumatol Cech. 2019; 86(2):156-158 | DOI: 10.55095/achot2019/023  

Stress fractures are common injuries in athletes. They result from excessive, repetitive loads on the normal bone which can cause an imbalance between bone resorption and formation, because during periods of intense exercise, bone formation lags behind bone resorption. The most common locations for stress fractures are weight-bearing bones of the lower extremities. This kind of injuries can easily be missed because they usually do not follow an acute injury in a fit young athlete, and plain radiographs usually appear normal.In this paper, a case of an amateur triathlete who suffered from a bilateral distal tibial stress fracture is presented.
