Acta Chir Orthop Traumatol Cech. 2010; 77(1):13-17 | DOI: 10.55095/achot2010/002  

PURPOSE OF THE STUDYRecent years have seen an increase in cementless total hip endoprosthesis (THP) implantations. Easy radiological measurement of wear in cups coated with X-ray dense material, such as metal or ceramics, is not applicable. An alternative technique has thus been developed to radiographically measure wear on cementless spherical implants.MATERIAL AND METHODSThe authors present a method in which the center of the head of the prosthesis relative to the center of the cup was defined by graphical extrapolation. Changes between the two centers on subsequent images allowed the estimation of wear. Data from 148 randomly selected...

Acta Chir Orthop Traumatol Cech. 2010; 77(1):18-23 | DOI: 10.55095/achot2010/003  

PURPOSE OF THE STUDYTo evaluate, in a retrospective study, injuries to the urogenital tract in patients with pelvic ring fractures.MATERIALIn the years 1998-2007, a total of 308 patients with pelvic ring fractures were treated. The study did not comprise patients with low-energy fractures, such as apophyseolysis in children, osteoporotic bone fractures or pathologic fractures. It also did not include patients with multiple injuries who died within 6 hours of admission to the hospital. The group consisted of 186 men and 122 women with an average age of 34 (range, 6 to 76) years.RESULTSThe fractures sustained were classified as type...

Our Experience with AES Total Ankle ReplacementOriginal papers

S. POPELKA, P. VAVŘÍK, I. LANDOR, J. HACH, J. PECH, A. SOSNA

Acta Chir Orthop Traumatol Cech. 2010; 77(1):24-31 | DOI: 10.55095/achot2010/004  

PURPOSE OF THE STUDYThe method of choice for the treatment of severe ankle arthritis is either arthrodesis or joint arthroplasty. Each has its advantages and disadvantages. Arthrodesis is the definitive therapy for severe ankle destruction and instability. Joint arthroplasty has an advantage in maintaining ankle mobility. However, its range of indications and its reliability and durability are more limited. The aim of this study is to present our experience with the AES prosthesis and draw attention to some drawbacks of this surgical treatment.MATERIALFrom September 2003 till June 2008, 51 AES ankle replacements were carried out in 51 patients...

Monteggia Lesions in the Growing Skeleton: Principles of TherapyOriginal papers

T. PEŠL, P. HAVRÁNEK

Acta Chir Orthop Traumatol Cech. 2010; 77(1):32-38 | DOI: 10.55095/achot2010/005  

PURPOSE OF THE STUDYIn this retrospective study we analyse the methods of Monteggia lesion (ML) treatment in children used in our department. Based on the results we propose several general principals for the therapy of this complex injury to the forearm in a growing skeleton.MATERIALThe group included patients with the diagnosis of acute ML treated at our department in the 2003-2007 period. No patients in whom therapy was started later than two weeks after injury were included.METHODSWe assessed injuries according to the Bado classification system modified by Olney for young age, and also by the system based on ML stability assessment...

Magnetic Resonance Imaging for Detection of Rotational Deformities in Children with Femoral Shaft Fractures Treated by the ESIN MethodOriginal papers

L. PLÁNKA, P. CHALUPOVÁ, M. CHARVÁTOVÁ, J. POUL, P. GÁL

Acta Chir Orthop Traumatol Cech. 2010; 77(1):39-42 | DOI: 10.55095/achot2010/006  

PURPOSE OF THE STUDYThe aim of the study was to evaluate the results of elastic stable intramedullary nailing (ESIN).used in the treatment of children with femoral shaft fractures, with a focus on post-traumatic rotational deformity assessed by magnetic resonance imaging (MRI). An alternative hypothesis was established assuming a significantly high incidence of this post-traumatic complication. Also, the advantages of MRI for the diagnosis of rotational deformity were assessed in comparison with ultrasonography and physical examination.MATERIAL AND METHODSA total of 26 patients, 18 boys and 8 girls, between 6 and 14 years of age (average,...

Low-Grade Renal Trauma (Part I): Diagnostic Validity of HaematuriaOriginal papers

R. GRILL, V. MAŠKOVÁ, V. RYANTOVÁ, M. URBAN

Acta Chir Orthop Traumatol Cech. 2010; 77(1):43-45 | DOI: 10.55095/achot2010/007  

PURPOSE OF THE STUDYThe aim of the study was to evaluate the diagnostic validity of haematuria findings in patients with low-grade renal trauma.MATERIAL AND METHODSThe group studied comprised the patients hospitalised between 1994 and 2008 in the University Hospital Královské Vinohrady, Prague, for blunt renal trauma, classified as grade I or grade II according to the Organ Injury Scaling Committee of the American Association for the Surgery of Trauma, in whom trauma to the lower urinary tract (urinary bladder and urethra) was excluded because of the mechanism of injury (direct blow to the kidney region) or by clinical examination or imaging...

Acta Chir Orthop Traumatol Cech. 2010; 77(1):46-51 | DOI: 10.55095/achot2010/008  

PURPOSE OF THE STUDYTo evaluate, in a retrospective study, the surgical outcomes of percutaneous A1 pulley release in the treatment of trigger digits.MATERIALThe group evaluated comprised 100 digits in 88 patients. There were 65 women and 23 men. Ten patients had surgery on two digits and one patient on three digits. The patients' average age at the time of surgery was 57.9 years. This procedure was performed on 55 thumbs and 45 fingers (4 index fingers, 19 middle fingers, 19 ring fingers, and 3 little fingers).METHODSA bent hypodermic needle is used to release the A1 pulley, whose localization is determined as suggested by Froimson....

M. MIŠKEJ, J. KUBÁLEK, D. BUZEK

Acta Chir Orthop Traumatol Cech. 2010; 77(1):52-57 | DOI: 10.55095/achot2010/009  

PURPOSE OF THE STUDYTo present the authors' own experience with Scarf osteotomy in a group of patients treated by this technique in their institution since 2004, together with emphasis on the aspects leading to successful outcome as well as to potential complications.MATERIALBetween May 2004 and January 2008, 70 operations were performed in 60 patients, 50 women and 10 men, with an average age of 56 years. The use of an appropriate surgical technique was decided on the basis of the IMA angle, as seen on an anteroposterior load radiograph of the forefoot. Scarf osteotomy was indicated when the angle was 12 to 20 degrees. There were 21 Scarf...

Radial Head ArthroplastyCurrent concepts review

M. T. KLEINER, A. M. ILYAS, J. B. JUPITER

Acta Chir Orthop Traumatol Cech. 2010; 77(1):7-12 | DOI: 10.55095/achot2010/001  

In conclusion, radial head fractures with 3 or more fragments have a high incidence of complications when treated with ORIF including hardware failure, malunion, nonunion, and the need for re-operation. Radial head arthroplasty has demonstrated good success in the treatment of complex, comminuted radial head fractures which are not amenable to non-opeative treatment or ORIF. Success can be optimized by diligent surgical dissection, avoiding inadvertent nerve injury, placement of an appropriately sized implant, repair of associated injuries, and early protected motion.

Perilunar Dislocation of the Corpus in a Patient with Aplasia of the ScaphoidCase report

J. ŠILLER, J. PILNÝ, M. SIROVÝ, M. MRKLOVSKÝ

Acta Chir Orthop Traumatol Cech. 2010; 77(1):58-60 | DOI: 10.55095/achot2010/010  

Congenital aplasia of the scaphoid is a rare abnormality arising when the distal row of carpal bones is dislocated radially and proximally, the capitate replaces the scaphoid, and the lunate is triangular instead of quadrilateral in shape. The scaphoid bone which makes a functional bridge between the proximal and the distal row is a stabilising element under normal anatomical conditions. If it is absent, the carpus structure is disturbed and its radial part is prone to perilunar dislocation, because stability is provided only by the ligaments. However, a perilunar dislocation associated with aplasia of the scaphoid has not been described in the literature...

Seat-Belt Syndrome in a Pre-School ChildCase report

J. MATĚJKA, K. PIZINGEROVÁ, V. VACEK, J. ZEMAN

Acta Chir Orthop Traumatol Cech. 2010; 77(1):61-64 | DOI: 10.55095/achot2010/011  

The authors report on a pre-school child with a typical presentation of the trauma caused by a car safety belt and termed the seat-belt syndrome. The deceleration mechanism which throws the upper body forward in the presence of a rigid belt over the abdominal region results in large contusions of the abdominal wall and trauma to the spine, retroperitoneum, and intra-abdominal organs, or even the chest. In making the diagnosis a thorough examination of the spine is necessary as well as a repeated surgical examination of the abdomen, because seat-belt syndrome is often associated with small intestine rupture, a symptom which can remain unrecognised at...
