PURPOSE OF THE STUDYNon-operative and operative treatment of acetabular fractures is associated with a risk of development of posttraumatic avascular necrosis of femoral head or with the development of posttraumatic coxarthrosis. The purpose of the study was to identify the occurrence of these two complications in patients in our group and to determine the risk factors for the development of these complications.MATERIAL AND METHODSThe retrospective study was conducted in two Level I trauma centres in the period from 2009 to 2014. The group included patients with an acetabular fracture. The inclusion criteria were the following: outpatient...

PURPOSE OF THE STUDYConsidered to be one of the most common causes of aseptic loosening of endoprostheses is the THA failure due to the wear of articulating components, UHMWPE in particular. The purpose of this study is to verify, in terms of oxidative damage and other parameters, the differences between the UHMWPE implants made by various manufacturers explanted for aseptic loosening with the same life span in vivo.MATERIAL AND METHODSIn the period 2010-2015, a total of 21 THA articulating components (cups) made of Ultrahigh molecular weight polyethylene by seven different manufacturers were explanted. For each manufacturer, three UHMWPE...

P. FULÍN, M. ŠLOUF, S. KREJČÍKOVÁ, J. HROMÁDKOVÁ, D. JAHODA, D. POKORNÝ

Acta Chir Orthop Traumatol Cech. 2019; 86(6):397-402 | DOI: 10.55095/achot2019/067  

PURPOSE OF THE STUDYPeriprosthetic joint infection is a major complication which in most of the cases requires a long-term administration of antibiotics and often necessitates undergoing multiple challenging surgeries. Bacterial adhesion to foreign material is one of the key risk factors associated with periprosthetic joint infection. The foreign material with large adhesion area might be also the UHMWPE (Ultrahigh molecular weight polyethylene) particles released during the wear process from the surface of articulating components. The purpose of this study is to evaluate potential adhesion areas of wear particles in relation to diverse distribution...

Acta Chir Orthop Traumatol Cech. 2019; 86(6):403-412 | DOI: 10.55095/achot2019/068  

PURPOSE OF THE STUDYAtlantoaxial Rotatory Dislocation (AARD) mostly occurs in children and prevailing majority of cases are successfully managed by non-operative treatment. Surgical intervention is necessary in patients in whom non-operative treatment failed, in case of repeated dislocations and in patients with anatomical defects of the atlantoaxial complex. The purpose of the presented study is the radiological and clinical evaluation of patients with AARD surgically treated at our department.MATERIAL AND METHODSIn the period from 2001 to 2017, altogether 15 patients with AARD were surgically treated at our department, namely 6 men and...

Acta Chir Orthop Traumatol Cech. 2019; 86(6):413-418 | DOI: 10.55095/achot2019/069  

PURPOSE OF THE STUDYThe retrospective study aims to compare the outcomes of augmentation of neutral triangle formed after the calcaneal fracture reduction with osteosynthesis using the locking compression plate with the outcomes of osteosynthesis without augmentation.MATERIAL AND METHODSIn the period from 2005 to January 2011, 98 patients with 114 calcaneal fractures were treated by open reduction and internal fixation (ORIF) method with the use of calcaneal plate. The group included 15 women (15.3%) and 83 men (84.7%), with the mean age of 39.2 years (12-62 years). There were 16 cases of bilateral calcaneal fractures, of which 2 in women...

Peroneal Nerve Palsy Management by Tibialis Posterior Muscle Transposition - Anatomical and Clinical StudyOriginal papers

P. HÁJEK, J. PILNÝ, H. VODOVÁ, K. HORÁČKOVÁ, D. KACHLÍK

Acta Chir Orthop Traumatol Cech. 2019; 86(6):419-422 | DOI: 10.55095/achot2019/070  

PURPOSE OF THE STUDYTransposition of tibialis posterior muscle ranks among the methods of dorsiflexion restoration in patients with peroneal nerve palsy. Even though this method is commonly used, anatomical variations are still encountered which make us modify the established procedures. The purpose of this study is to evaluate the functional outcomes of operated patients and based on the clinical experience to define by cadaver preparation the anatomical causes preventing the use of the standard transposition technique.MATERIAL AND METHODSThe clinical group includes 21 patients (15 men, 6 women) with the mean age of 34.2 years and with...

InternalBrace ACL Repair - First Experiences and OutcomesOriginal papers

PURPOSE OF THE STUDYCranioplasty is currently the most common neurosurgical procedure. The purpose of this study is to describe the first experience with successful use of the Cranio-Oss (PEEK) custom implant for cranioplasty.MATERIAL AND METHODSIn the period 2012 to 2013, a total of 26 cranioplasties were performed. In fourteen patients, their own bone flap was used for reconstruction. In four cases, a synthetic Cranio-Oss bone implant made of PEEK was used. In six patients, the defect was covered by an intraoperatively-made Palacos implant and in two cases, minor defects were covered with a titanium mesh. The patients were followed up...

Liver Injury after a Collapse Caused by Acute Myocardial Infarction, Resuscitation and Acute Myocardial RevascularisationCase report

T. SKALICKÝ, A. SKALICKÝ

Acta Chir Orthop Traumatol Cech. 2019; 86(6):444-446 | DOI: 10.55095/achot2019/074  

The presented case report describes primarily an unrecognized liver injury after the resuscitation with cardiac massage due to myocardial infarction. After myocardial revascularization, the hemodynamic instability and anaemia in the patient persisted. The performed CT scan confirmed a liver injury, namely the rupture of liver parenchyma with hemoperitoneum, which had to be treated surgically. It represents a complication of cardiac massage that occurs, though less frequently.
