INTRODUCTIONInformation on the distribution of UHMWPE wear particles around joint replacements is essential for the understanding of aseptic loosening of implants.MATERIAL AND METHODSSamples of soft tissue from around total hip arthroplasty (THA), which had a typical appearance of polyethylene granuloma, were collected from the places corresponding to the radiological zones of Gruen and DeLee. The samples were taken from 45 patients (group N1). Since the samples varied in macroscopic appearance and/or the technique of processing, a sub-group of 15 more uniform samples (group N2) were collected by the first author in order to ensure...

PURPOSE OF THE STUDYComplete disruption of the scapholunate (SL) ligament results in the development of arthritic lesions known as scapholunate advanced collapse (SLAC) of the wrist.MATERIAL AND METHODSThe authors present the results of a prospective study of seven patients in whom radiography showed an acute complete rupture of the scapholunate ligament and who refused SL ligament reconstruction. This group (1) was compared with a group of 17 patients (2) who underwent ligament reconstruction soon? after an acute rupture had been detected. All patients were examined at 36 months after injury for hand function and pain using the Wrightington...

Screw Loosening after Posterior Dynamic Stabilization - Review of the LiteratureOriginal papers

T. KOCAK, B. CAKIR, H. REICHEL, T. MATTES

Acta Chir Orthop Traumatol Cech. 2010; 77(2):134-139 | DOI: 10.55095/achot2010/025  

PURPOSE OF THE STUDYThe malposition of pedicle screws in the lumbar spine is associated with a potential risk of iatrogenic injury of neurological structures but also with a decrease of biomechanical stability. The correct position of the pedicle screws of a dynamic stabilization device, as a long-term implant, seems to be of great importance. A high incidence of screw loosening could influence both the rate of revision surgeries and the clinical results. We compared screw loosening in our own patients with published data after navigated and non-navigated implantation of Dynesys.MATERIAL AND METHODSPosterior instrumentation with the Dynesys...

PURPOSE OF THE STUDYThe aim of the study was to verify whether ultrasonography can be considered a reliable method for the diagnosis of low-grade renal trauma.MATERIAL AND METHODSThe group investigated included patients with grade I or grade II blunt renal trauma, as classified by the AAST grading system, in whom ultrasonography alone or in conjunction with computed tomography was used as a primary diagnostic method.B-mode ultrasound with a transabdominal probe working at frequencies of 2.5 to 5.0 MHz was used. Every finding of post-traumatic changes in the renal tissues, i.e., post-contusion hypotonic infiltration of the renal parenchyma...

A Palmar Percutaneous Volar versus a Dorsal Limited Approach for the Treatment of Non- and Minimally-Displaced Scaphoid Waist Fractures: An Assessment of Functional Outcomes and ComplicationsOriginal papers

P. DRÁČ, P. MAŇÁK, I. ČIŽMÁŘ, J. HRBEK, J. ZAPLETALOVÁ

Acta Chir Orthop Traumatol Cech. 2010; 77(2):143-148 | DOI: 10.55095/achot2010/027  

PURPOSE OF THE STUDYNon-displaced or minimally displaced scaphoid waist fractures can be surgically treated using either the percutaneous volar or the limited dorsal approach. These techniques provide a possibility of early wrist physiotherapy throughout the healing period, better functional outcomes and a shorter sick leave duration. Many reports cite low complication rates. The purpose of this study is to compare both techniques based on the complication rate and functional outcomes.MATERIAL AND METHODSThe authors compared 42 patients treated for an acute scaphoid waist fracture by percutaneous osteosynthesis and 38 patients treated by...

Comprehensive Therapy of Symptomatic Vertebral HaemangiomasCase report

L. HRABÁLEK

Acta Chir Orthop Traumatol Cech. 2010; 77(2):149-153 | DOI: 10.55095/achot2010/028  

Vertebral haemangiomas (VH) are usually asymptomatic and are often found incidentally at spinal examination by imaging methods. Nevertheless, some haemangiomas can be clinically manifested by various degrees of axial pain and neurological deficit. The aim of this report is to show that this is a complex issue that requires a comprehensive approach to its treatment. The author reports on three patients with aggressive forms of cervical and lumbar VH treated by radiation therapy or vertebroplasty and hemilaminectomy with resection of the intraspinal thoratic component of a tumour. He discusses his findings in relation to the scarce data found on this...
