PURPOSE OF THE STUDYOur study aimed to assess the mid-term outcomes and complications with the ICON hip resurfacing system and to carry out a detailed analysis of pitfalls and risks associated with pairing the bearing surfaces of metal-on-metal hip implants.MATERIAL AND METHODSA total of 52 hip joints were assessed in 43 patients who received the ICON hip resurfacing system at our department between 2009 and 2013. The cohort included 34 men and 9 women. Their age at the time of primary surgery ranged from 34 to 67 years, with the mean age of 51.8 years. The mean follow-up was 7.6 years. The evaluation focused on the position and osseointegration...

J. KNOR, V. PACOVSKÝ, V. NEDVĚD, K. KEHÁROVÁ, A. KURZOVÁ, J. MÁLEK

Acta Chir Orthop Traumatol Cech. 2022; 89(5):339-343 | DOI: 10.55095/achot2022/054  

PURPOSE OF THE STUDYMany physicians believe that loco-regional anaesthesia and analgesia improve the postoperative course of patients indicated for total hip arthroplasty compared to general anaesthesia. However, there are many patients who refuse subarachnoid or epidural anaesthesia, or have contraindications or conditions making the use of such techniques impossible. An alternative option is the combination of general anaesthesia and a peripheral nerve blockade. The aim of this prospective randomized open-label clinical trial was to compare the efficacy and quality of postoperative analgesia between fascia iliaca block combined with general...

C. KONRADS, S. DÖBELE, A. EIS, U. STÖCKLE, S. S. AHMAD

Acta Chir Orthop Traumatol Cech. 2022; 89(5):344-348 | DOI: 10.55095/achot2022/055  

PURPOSE OF THE STUDYTo characterize constitutional frontal alignment of the ankle in genua vara, valga, and norma.MATERIAL AND METHODSLong-leg standing radiographs of 589 patients presenting between 2011 and 2020 for knee-complaints because of any reason were chosen from our database. Cases with fractures or history of bony-realignment-surgeries were excluded. The Hip-Knee-Ankle angle (HKA), the mechanical Lateral Distal Tibia Angle (mLDTA), and the Tibia-Plafond-Horizontal-Orientation angle (TPHA) were measured in 354 patients. For this study, neutral frontal alignment of the leg was defined as HKA between -3.0° and +4.0°. HKA-values 4.0°...

Locking Nail versus Plate Fixation in Calcaneal Fractures: Brief report on a Retrospective Analysis of Treatment Characteristics and Radiographic Correction PotentialOriginal papers

N. STACHEL, B. J. BRAUN, M. ORTH, S. C. HERATH, M. F. R. ROLLMANN, M. M. MENGER, T. HISTING, T. POHLEMANN

Acta Chir Orthop Traumatol Cech. 2022; 89(5):349-352 | DOI: 10.55095/achot2022/056  

PURPOSE OF THE STUDYMinimal and limited access techniques are gaining increasing interest for the treatment of displaced intra-articular calcaneal fractures. The ideal treatment method is however still debated and largely based on individual case factors and surgeon experience. Aim of this study was thus to compare the treatment characteristics and radiographic correction potential of a locking nail system with a sinus tarsi approach to plate fixation via an extended lateral approach.MATERIAL AND METHODSWe retrospectively reviewed 39 cases of patients with calcaneal fractures that received primary fracture treatment for displaced intra-articular...

Tibiotalocalcaneal Arthrodesis: Comparison of Fixation Methods, Mid-Term Clinical ResultsOriginal papers

J. RAPI, L. NACHTNEBL, M. MAHDAL, V. APOSTOLOPOULOS, J. LISKAY, T. TOMÁŠ

Acta Chir Orthop Traumatol Cech. 2022; 89(5):353-359 | DOI: 10.55095/achot2022/057  

PURPOSE OF THE STUDYThe authors focused on the topic of tibiotalocalcaneal arthrodesis. It is a surgical procedure used to manage severe comprehensive ankle and hindfoot pathology. The scope of surgery and the negative impact on the walking stereotype are offset by preserving a weight-bearing and pain-free limb. The purpose of the study was to evaluate the group of patients who had undergone surgery at the First Department of Orthopaedic Surgery, St. Anne s University Hospital Brno and to identify the most suitable fixation for arthrodesis. It also aimed to compare the outcomes achieved by the authors with those reported by other departments.MATERIAL...

Acta Chir Orthop Traumatol Cech. 2022; 89(5):360-369 | DOI: 10.55095/achot2022/058  

PURPOSE OF THE STUDYAseptic pseudoarthrosis (nonunion, PSA) of the humeral shaft is one of the serious complications in the treatment of fractures in this area. In a retrospective study, the authors described different methods of treating patients with this complication using predictive factors.MATERIAL AND METHODSBased on the definition of nonunion and the criteria, 14 patients (N=14) with the mean age of 56 years (32-78), namely 8 men and 6 women were included in the study. All patients were followed up clinically and radiologically at 1, 3, 6, 9, 12 months and every 3 months until the condition stabilized. The follow-up period...

PURPOSE OF THE STUDYNitinol (NiTi) is a biomaterial widely used in medicine based on super-elastic and shape memory properties. miR-124 has a key role in inflammatory process, osteoblasts differentiation, and mineralization. The aim of study was evaluating the differences in gene expression of miR-124 of human physiological osteoblasts (HOB) and human osteoarthritic osteoblasts (OSBA) as a response to NiTi alloy in different heat treatments.MATERIAL AND METHODSThe cells were cultivated with NiTi discs with/without addition of bacterial lipopolysaccharide (LPS) for 72 hours. MicroRNAs were isolated, underwent reverse transcription and were...

M. ŠEVČÍK, T. UHRIN, D. VIDOVIČ

Acta Chir Orthop Traumatol Cech. 2022; 89(5):380-383 | DOI: 10.55095/achot2022/061  

Glenohumeral joint is the most frequently dislocated joint of the human body. Concomitant fractures of the coracoid process and tuberculum majus in humeral dislocation of the shoulder joint are rarely described. Concomitant fractures are results of a significant contraction of the surrounding muscles and rotator cuff during a cerebral paroxysm. Due to the small number of cases, the treatment of such injuries is not simple and it is based on an algorithm for treatment of isolated injuries of these anatomical structures.In this case report, we describe a concomitant fracture of the coracoid process and tuberculum majus during an anterior shoulder...
