PURPOSE OF THE STUDY Different techniques have been reported to reconstruct the deficient acetabulum during total hip arthroplasty (THA). The purpose of this study was to compare the biomechanical features of the bulk bone graft (BBG) technique (Harris acetabular plasty) and the Roof Step Cut (RSC) technique using finite element analysis. MATERIAL AND METHODS Based on a female patient's dysplastic hip CT scan, 3D models were assembled according to the two techniques. For the Harris technique, an irregular BBG was sculpted from a solid sphere, while for the RSC technique, the graft was sculpted into a step-cut shape with a similar size. Each graft was...

Purpose of the study The purpose of this study was to minimize tourniquet-induced ischemia-reperfusion injury (IRI) in total knee arthroplasty (TKA) surgery using the remote ischemic preconditioning (RIPC) model, as well as to assess antioxidant balance with thiol-disulfide homeostasis (TDH). The secondary goal is to evaluate the impact of RIPC on TKA clinical outcomes. Material and Methods Patients in the ASA I-III group who underwent elective TKA were enrolled in this prospective, randomized, double-blind clinical research. TDH parameters were measured individually in groups with (Group I) and without (Group K) RIPC at the following times: preoperative...

Purpose of the study This study aims to analyse a subpopulation of patients with severe haemorrhagic shock and a concurrent unstable pelvic ring fracture. Material and methods This manuscript is a retrospective study of prospectively collected data on trauma patients over a period of 10 years, namely between 2010 and 2019. These patients, primarily (after injury) referred to the trauma centre of the University Hospital Hradec Králové, were diagnosed with an unstable pelvic ring fracture as a part of multiple injuries. Results The total number of patients with a pelvic ring fracture and concurrent acute phase of decompensated haemorrhagic shock in...

Acta Chir Orthop Traumatol Cech. 2023; 90(5):329-334 | DOI: 10.55095/achot2023/039

PURPOSE OF THE STUDY Extended lateral approach to calcaneus fractures is associated with a high risk of infection. Such risk can be reduced by using mini-invasive approaches. The sinus tarsi approach provides a good overview of the posterior joint facet of the calcaneus and can also be done as a mini-invasive procedure. The authors present their first experience with osteosynthesis of joint depression calcaneal fractures using the anterolateral locking plate inserted through the sinus tarsi approach. MATERIAL AND METHODS During the period from 1 February 2020 to 31 January 2022, 18 patients were treated by the anterolateral locking plate in the authors'...

Acta Chir Orthop Traumatol Cech. 2023; 90(5):335-339 | DOI: 10.55095/achot2023/040

PURPOSE OF THE STUDY The study aimed to propose an optimal based flap creation with the view to ensure long-term survival of the interposition arthroplasty. MATERIAL AND METHODS A total of 28 dorsal wrist capsules were collected from 16 cadavers (with age range at death 18 to 80 years, with no visible wrist pathology). Altogether 112 histological specimens were obtained from these 28 samples. Post-hoc Dunn's tests were used to analyse the percentage of vascularisation of individual sides of the dorsal capsule (circumference and area) at the 0.05 level of significance. Spearmann's correlation analysis was used to assess the effect of age on vascularization...

Purpose of the study Femoroacetabular impingement syndrome is a complex, often post-traumatically developing impairment of the hip joint, characterized by ambiguous symptomatology, which makes early diagnosis difficult, especially in the early stages. Experimental retrospective study was carried out to evaluate the usability of a triaxial gyroscopic sensor in routine practice as an additional indication criterion for operative versus conservative treatment procedures. MATERIAL AND METHODS 92 patients were included in the retrospective study, and 62 completed the investigation. All patients signed informed consent. A gyroscopic sensor was placed on...

Acta Chir Orthop Traumatol Cech. 2023; 90(5):347-352 | DOI: 10.55095/achot2023/042

Purpose of the study The competence of the anterior translation of tibia (ATT), posterior cruciate ligament angle (PCLA), and femorotibial rotation angle (FTRA) measured on MR images in predicting anterior cruciate ligament (ACL) injury was evaluated in this study. Material and methods 266 patients who underwent diagnostic arthroscopy between 2015-2020 were included in this study. Age, gender, radiological findings included ATT, PCLA, and FTRA were measured on preoperative MR images of all patients. Results ACL tear was detected in 143 of patients and most of them were younger males. In ACL-R group, the ATT was 7 mm (-4-17 mm), PCLA value was 110º...

Acta Chir Orthop Traumatol Cech. 2023; 90(5):353-357 | DOI: 10.55095/achot2023/043

The authors present the cases of monozygotic male twins with right-sided Legg-Calvé-Perthes disease (LCPD) with different formation of the lumbosacral junction. This is likely the first description of a lumbosacral junction formation disorder associated with identical twins who were both treated for LCPD as children. The disease began at 6 and 9 years of age and during treatment as well as in adulthood significantly different bone formation of the lumbosacral transitional vertebra, was observed in both brothers. Twin A has a unilateral right-sided fusion of the enlarged L5 transverse process with the ipsilateral sacral ala, twin B has a complete sacralization...
