Tranexamic Acid Reduces the Incidence of Heterotopic Ossifications after Elective Primary Total Hip ArthroplastyOriginal papers

J. DEBRE, Z. ŠTĚPÁN, J. DUPAL

Acta Chir Orthop Traumatol Cech. 2021; 88(1):13-17 | DOI: 10.55095/achot2021/003  

PURPOSE OF THE STUDYHeterotopic ossification is a frequent and a well-known complication after elective primary total hip arthroplasty. Prophylaxis is crucial since once the ossification is mature, the only treatment option is its surgical removal during revision hip surgery. There are pre-, peri- and postoperative prophylactic modalities. Ranking among the perioperative possibilities is the application of tranexamic acid in blood control management. The aim of our study is to prove the positive side effect of tranexamic acid application on reducing the heterotopic ossification ratio.MATERIAL AND METHODSA cohort of 401 total hip replacements...

Acta Chir Orthop Traumatol Cech. 2021; 88(1):18-27 | DOI: 10.55095/achot2021/004  

PURPOSE OF THE STUDYTwo-year clinical results of a multicenter prospective randomized study in patients with arthroscopically treated Femoroacetabular Impingement syndrome and concurrently performed microfracture for grade IV chondral lesions of the acetabulum.MATERIAL AND METHODSThe study evaluated a group of 55 patients of the originally enrolled 92 patients with the underlying diagnosis of FAI syndrome with intraoperatively confirmed grade IV acetabular chondropathy of up to 4 cm² in size, who had undergone a comprehensive hip arthroscopy (correction of structural cam-type and/or pincer-type deformity, labral refixation or...

Causes for Delay to Surgery in Hip Fractures and How It Impacts on Mortality: a Single Level 1 Trauma Center ExperienceOriginal papers

A. KRISTAN, S. OMAHEN, M. CIMERMAN

Acta Chir Orthop Traumatol Cech. 2021; 88(1):28-34 | DOI: 10.55095/achot2021/005  

PURPOSE OF THE STUDYThe increasing number of hip fractures puts enormous demand on our level 1 trauma centre. Because we have to synchronize hip fracture treatment with all other injuries delays to surgery can occur. In this study, we analysed the reasons for delay to surgery and how it impacts on mortality of hip fracture patients in our institution.MATERIAL AND METHODSWe retrospectively studied 641 patients operated for hip fractures in one year period. Investigated characteristics were: age, gender, American Society of Anaesthesiologists score (ASA), time of hospital admission, time of surgery, type of surgery, anticoagulant therapy...

Acta Chir Orthop Traumatol Cech. 2021; 88(1):35-38 | DOI: 10.55095/achot2021/006  

PURPOSE OF THE STUDYSacroiliac joint dysfunction is defined as a permanent chronic pain originating from the sacroiliac joint, limiting the patient's daily activities. The purpose of this study was to evaluate the effectiveness of the minimally invasive sacroiliac joint stabilization by triangular titanium implants in patients with sacroiliac joint dysfunction.MATERIAL AND METHODSThe prospective study evaluated the patients who had underwent a minimally invasive sacroiliac joint stabilization for sacroiliac joint dysfunction with the use of iFuse® implants. The surgery was performed solely under fluoroscopic guidance or together with...

Rotational Stability of the Knee Joint 2 Years after the Anterolateral Ligament and ACL Reconstruction: Biomechanical StudyOriginal papers

M. KOMZÁK, R. HART, D. NÁHLÍK, R. VYSOKÝ

Acta Chir Orthop Traumatol Cech. 2021; 88(1):39-44 | DOI: 10.55095/achot2021/007  

PURPOSE OF THE STUDYKnee injuries accompanied by anterior cruciate ligament (ACL) tears can also result in rotational instability of the joint. Subsequent insufficient rotational stability after the ACL reconstruction can be a direct consequence also of injuries to lateral knee structures, specifically the anterolateral ligament (ALL). This residual postoperative rotational instability may be prevented by multiple surgical techniques. The purpose of this study was (1) to evaluate the knee stability in internal rotation after the "anatomical" single-bundle (SB) anterior cruciate ligament reconstruction together with ALL reconstruction compared to...

Toddler's Fractures: Definition, Differences between the Diagnostic and Therapeutic ApproachOriginal papers

A. KNÍŽETOVÁ, R. ZELENKOVÁ, T. PEŠL, P. HAVRÁNEK

Acta Chir Orthop Traumatol Cech. 2021; 88(1):45-49 | DOI: 10.55095/achot2021/008  

PURPOSE OF THE STUDYThe term toddler's fracture was first coined by J. S. Dunbar in 1964 as a nondisplaced fracture of the distal tibia in children aged 9 months to 3 years. Over time, many other authors extended this definition as to the location as well as age range. The purpose of this paper is to provide a comprehensive overview of the existing studies focusing on the topic of toddler's fractures, to compare individual diagnostic and therapeutic approaches, and to specify the term toddler's fracture. Also, a group of patients with this diagnosis is presented, treated at our department.MATERIAL AND METHODSA retrospective study of a group...

Mid-Term Results of Proxima Ultra-Short Anatomical Stem: Analysis of 130 CasesOriginal papers

M. MELIŠÍK, M. HRUBINA, J. HEŘT, Z. CIBULA, J. ČABALA, L. NEČAS

Acta Chir Orthop Traumatol Cech. 2021; 88(1):50-57 | DOI: 10.55095/achot2021/009  

PURPOSE OF THE STUDYThe aim of this study is to assess the mid-term results of this specific ultra-short, cementless stem in patients younger than 60 years with regard to clinical and radiographic outcomes, survivorship, complication rate and revisions.MATERIAL AND METHODSA consecutive series of one hundred and twenty-one patients (130 hips) younger than 60 years at the time of surgery was enrolled in the study. Primary arthritis (33.8%) and dysplastic hips (30%) were the most common diagnoses. The patients used crutches for 6 weeks to protect femoral components against subsidence and rotational stress. The mean follow-up was 118 months...

Is Peroneus Longus Allograft Good Alternative for Anterior Cruciate Ligament Reconstruction: a Comparison StudyOriginal papers

R. ERTOGRUL, A. VAROL, Y. OC, B. E. KILINC

Acta Chir Orthop Traumatol Cech. 2021; 88(1):58-62 | DOI: 10.55095/achot2021/010  

PURPOSE OF THE STUDYTo compare the early clinical results of patients who had anterior cruciate ligament (ACL) reconstruction with peroneus longus allograft versus hamstring tendon autograft.MATERIAL AND METHODSForty patients who underwent ACL reconstruction were included in the study. Patients were grouped by their graft preference. Lachman and Pivot-shift tests were performed to the patients. Laxity was measured by KT-1000 arthrometer test with 15, 20 and 30 pound power. The maximum force values of nonoperated knee and the operated knee were recorded with Cybex II isokinetic dynamometer (HUMAC) and compared to each other. International...

Direct Radiography Following Fracture Reduction Improves the Reliability of Pauwels ClassificationOriginal papers

M. KUMBARACI, A. TURGUT, T. BACAKSIZ, G. ILYAS, E. BILGIN, Ö. KALENDERER

Acta Chir Orthop Traumatol Cech. 2021; 88(1):63-68 | DOI: 10.55095/achot2021/011  

PURPOSE OF THE STUDYPauwels classification system is widely used to classify the femoral neck fractures. Even its widely usage there are severals debates about its reliability. After the femoral neck fracture occured the lower extremity rotates externally and this external rotation deformity could lead to misevaluation of Pauwels angle at the initial radiographs. The purpose of our study is to investigate whether the reliability of Pauwels classification increases after reduction of femoral neck fractures.MATERIAL AND METHODSTwo power point presentation was prepared with 117 slides that include antero-posterior radiographs of each femoral...

Custom-Made 3D Printed Titanium Acetabular Component: Advantages and Limits of UseCase report

D. MACÁK, V. DŽUPA, M. KRBEC

Acta Chir Orthop Traumatol Cech. 2021; 88(1):69-74 | DOI: 10.55095/achot2021/012  

The authors report on three cases in which a custom-made 3D printed titanium acetabular component of total hip arthroplasty was used to manage an advanced acetabular bone defect with pelvic discontinuity. The implant surface structure impeded long-term bone integration. Nonetheless, the stable bridging of the acetabular defect resulted in full integration of impacted bone allografts at the base of the implant. The pelvic continuity was restored within 12 months after surgery, and thus the acetabulum was prepared for potential further implantation of a standard revision acetabular component. Only one of the three female patients underwent a revision...
