Acta Chir Orthop Traumatol Cech. 2020; 87(5):323-328 | DOI: 10.55095/achot2020/048  

PURPOSE OF THE STUDYAlthough the congenital short femur is morphologically well characterized, changes at the molecular level have not been described in the literature so far. The absence of such information, along with the unknown aetiology of the defect, was the motivation for analysing angiogenesis and osteogenesis in the pseudoarthrosis ( joint) tissue in PFFD patients compared to physiological bone. The authors expected differences in gene expression, particularly in the quantity of expressed genes.MATERIAL AND METHODSA piece of bone was removed during an elective surgery procedure, placed in an RNA stabilization reagent, which prevents...

Acta Chir Orthop Traumatol Cech. 2020; 87(5):329-332 | DOI: 10.55095/achot2020/049  

PURPOSE OF THE STUDYContinuous epidemiologic data on changes in the spectrum of acetabular fractures is rare. The purpose of this study is to evaluate changes in the types of acetabular fractures over the last two decades.MATERIAL AND METHODSIn the period between 2007 and 2016, a total of 522 patients were treated at the authors department (Traumacentre Level I) for acetabular fractures. 15 patients sustained bilateral fractures. The group consisted of 361 men and 161 women, with the mean age of 49 years (the range of 10-96 years).Standard procedure was applied to diagnose the fractures (X-ray and CT scan). Non-operative treatment was...

Acta Chir Orthop Traumatol Cech. 2020; 87(5):333-339 | DOI: 10.55095/achot2020/050  

PURPOSE OF THE STUDYArtificial cervical disc replacement (CDR) has emerged as a viable treatment alternative to fusion for the management of symptomatic compressive radiculopathy and potentially for cervical myelopathy. The aim of our study was to evaluate the clinical and radiological outcomes of patients treated with a second generation semi-constrained CDR with a ceramic-ceramic articulation.MATERIAL AND METHODSA prospective cohort study of all patients undergoing a cervical disc replacement for cervical disc pathology, during the period from April 2007 to April 2011 using a ceramic-ceramic disc replacement comprised the study group....

H.-C. KÖHLER, T. TISCHER, C. HACKE, A. GUTCKE, C. SCHULZE

Acta Chir Orthop Traumatol Cech. 2020; 87(5):340-345 | DOI: 10.55095/achot2020/051  

PURPOSE OF THE STUDYSubacromial impingement is one of the most common reasons for shoulder pain. The surgical management of this condition has recently become the focus of criticism because of the rising number of surgical procedures and the lack of superiority of surgical over conservative treatment. In this prospective comparative study, we compared standardised conservative care with surgical treatment and placed special emphasis on the patients' ability to work.MATERIAL AND METHODSA total of 106 patients (25 women, 81 men; mean age: 45.4 ± 12.3 years) were included in this prospective comparative clinical study. Patients in the...

Acta Chir Orthop Traumatol Cech. 2020; 87(5):346-349 | DOI: 10.55095/achot2020/052  

PURPOSE OF THE STUDYWe hypothesized that preoperative planning with 3D modeling of complex foot deformities would be useful for the education of orthopedics and traumatology residents.MATERIAL AND METHODSThis study is prospectively designed study with a control group. Twenty eight residents (study group) who assisted the surgeons during the interventions and ten senior surgeons (control group) were included in the study. All participants assessed virtual 3D-CT images and videos of the cases before the surgery.Ten adult cases of foot bone deformities were evaluated. 3D-CT reconstruction was performed and a 3D model of each deformity...

Comparison of Clinical and Radiological Results of Two Fixation Materials after Distal Chevron Osteotomy for Hallux Valgus? - Two Kirschner Wires versus Single Screw FixationOriginal papers

Acta Chir Orthop Traumatol Cech. 2020; 87(5):350-355 | DOI: 10.55095/achot2020/053  

PURPOSE OF THE STUDYAlthough distal chevron osteotomy (DCO) is considered as an intrinsically stable osteotomy, various fixation methods have been used to date. The purpose of this study was comparison of two commonly used methods in DCO, Kirschner (K)-wire and titanium fully threaded headless cannulated screw fixation, based on the clinical and radiological results, and their complications.MATERIAL AND METHODSThirty patients were included in K-wire group and 36 patients were included in screw group. Mean age was 43.4 11.1 (rage; 19-65) years, and mean follow-up was 21.2 5.5 (range; 12-35) months. American Orthopaedic Foot Ankle Society...

Biomechanics of Osteosynthesis in Periprosthetic Femoral Fractures Following Total Hip ArthroplastyCurrent concepts review

J. SKÁLA-ROSENBAUM, V. DŽUPA, M. KRBEC

Acta Chir Orthop Traumatol Cech. 2020; 87(5):309-317 | DOI: 10.55095/achot2020/046  

Periprosthetic femoral fractures around the femoral stem of a hip prosthesis constitute a serious challenge. The number of these fractures, associated with a high failure rate and a high number of overall complications, including higher mortality, has been on an increase worldwide. Stable femoral stems are indicated for osteosynthesis, while in case of loosening the method of choice is the replacement by a revision implant. The aim of osteosynthesis of periprosthetic femoral fractures is a stable fixation with soft tissue preservation which results in faster union allowing the patient to return to pre-injury activities. Biomechanical studies on cadavers...

Acta Chir Orthop Traumatol Cech. 2020; 87(5):318-322 | DOI: 10.55095/achot2020/047  

Anterior cruciate ligament (ACL) rupture is one of the most common traumatic injuries of the knee joint. Acute knee injury is often characterized by pain and the typical accompanying rupture sound. The injured person often feels pain in the knee, with swelling, the movement is painful in the full range of motion. The most commonly used test procedures for rupture include Lachman test, pivot shift test, anterior drawer and lever sign test. This review includes a description of individual tests and the diagnostic value of examination after the ACL rupture. The sensitivity and specificity of the lever sign test was 0.92-1.00, the specificity was 0.94-1.00....

Rare Vascular Complication after ACL ReconstructionCase report

M. HANUS, R. HUDÁK

Acta Chir Orthop Traumatol Cech. 2020; 87(5):356-359 | DOI: 10.55095/achot2020/054  

The anterior cruciate ligament reconstruction is currently one of the most commonly performed arthroscopic procedures of knee joint. Overall, it is a reliable and sophisticated procedure associated with a relatively low complication rate. In the available literature, less severe complications are reported in 3-7% of cases. The most frequent complications are intractable pain not manageable using analgesic therapy (6.7%), hemarthrosis requiring puncture (4.4%), fever (3.2%) and other complications related in particular to immobilisation (1.2%). The percentage of severe complications is very low (less than 1%). These include deep vein thrombosis (0.6%),...

K. ŠMEJKAL, L. MARŠÍK, J. ŠIMEK, M. FRANK, T. DĚDEK, J. PÁRAL

Acta Chir Orthop Traumatol Cech. 2020; 87(5):360-362 | DOI: 10.55095/achot2020/055  

The authors present a case of 74-year-old female patient who suffered a flail chest in motor vehicle accident. First day after injury a descending thoracic aorta was injured, most likely during manipulation with the patient. This injury was verified by operation, which was indicated 26 hours after the hospital admission, because of a sudden decrease of blood pressure with blood loss over 600 ml through the chest tube. The female patient died during surgery despite all efforts. Due to our experience with this rare case and after literature studying, we would recommend to consider early surgical revision. Based on the close contact of severely displaced...

Acute Limb Ischemia after Total Hip Arthroplasty in a High-Risk Patient - Is Tranexamic Acid to Blame?Case report

J. MASARYK, J. VIDAN, B. ŠTEŇO

Acta Chir Orthop Traumatol Cech. 2020; 87(5):363-366 | DOI: 10.55095/achot2020/056  

Tranexamic acid (TXA) is widely used to limit the blood loss during total joint arthroplasty without an increased risk of thromboembolic events. We present a case of acute limb ischaemia due to thrombotic occlusion of the superficial femoral artery on the non-operated limb following a total hip arthroplasty in a 64-year-old male patient. Untreated peripheral artery disease, intravenous TXA administration, surgery, obesity and hypertension were identified as predisposing factors of the occlusion. Good reperfusion of the limb was obtained after mechanical thrombectomy. Other cases report that antifibrinolytic agents such as TXA could be associated with...
