The long-term radiologically interpreted results of low-friction Charnley hip arthroplasties have been previously suggested to be influenced by surgical details, such as orientation of the femoral component, degree of coverage of the plastic acetabulum and other features. We carefully analyzed the radiographs of 135 Charnley arthroplasties that had remained functional, had not been revised and had follow-ups between 15 and 35 years. Several common denominators were identified amongst these radiographs: 93.5% arthroplasties had 100% coverage of the acetabular component; 88% had acetabular inclination between 40-45°; 84.5% had a proximal/medial column...

Acta Chir Orthop Traumatol Cech. 2006; 73(3):151-156 | DOI: 10.55095/achot2006/021  

PURPOSE OF THE STUDYIn the period from 06/00 to 08/02, 31 patients with odontoid fractures type Anderson II and III were treated and stastically recorded. 25 patients were followed up; the progess of 24, documented in detail radiographically, were evaluated independently by a traumatologist and by a radiologist.The usual time of immobilization when treating odontoid fractures type Anderson type II and III with the halo-fixator is 12 weeks. For this 12 weeks that it is worn, objective assessment of bone healing is performed radiographically and the results critically considered in terms of the length of time that the halo-fixator should be worn...

Acta Chir Orthop Traumatol Cech. 2006; 73(3):157-163 | DOI: 10.55095/achot2006/022  

PURPOSE OF THE STUDYThe Burch-Schneider cages (BSC) are designed to manage severe acetabular defects by bridging large bone gaps and preventing medial and superior migration of the prosthetic cup. The purpose of the study was to evaluate the results of such revisions after prolonged follow-ups.MATERIAL AND METHODSFrom 1985 to 2000 sixty-nine acetabular revisions with BSC were performed in 68 patients with an acetabular defect classified as type Paprosky 3A (32) and 3B (37) at our institutions. After meticulous debridement of the entire acetabulum cancellous chips were pressurized into the bone defects to restore the hemispherical shape....

PURPOSE OF THE STUDYIn this retrospective evaluation the authors present the group of patients with intraarticular calcaneal fractures that were treated from an extended lateral approach.MATERIALIn the period from 2001 to 2003, 32 patients with intra-articular calcaneal fractures were treated by osteosynthesis, using a plate, from the extended lateral approach. All patients were men at an average age of 41.7 years (range, 20 to 63 years). The most frequent cause of injury was a fall from height. A combined injury was recorded in eight patients. The right calcaneus was broken in 11 and the left one in 21 patients. Patients with bilateral...

PURPOSE OF THE STUDYSeveral options for treatment of valgus deformity in total knee arthroplasty (TKA) have been described. In 2002 the lateral approach to the valgus knee with Z-plasty of the articular capsule involving part of Hoffa's fat pad started to be used in our department. In this study the surgical technique, including steps for gradual deformity correction, is described and short-term results are evaluated.MATERIALA total of 1136 TKAs were carried out in the period from 1994 to 2004; of these 131 (11 %) were performed on valgus knee. After a visit to the Schulthess Klinik and personal communication with Dr. med. T. Drobny, we...

Acta Chir Orthop Traumatol Cech. 2006; 73(3):176-182 | DOI: 10.55095/achot2006/025  

PURPOSE OF THE STUDYThe aim of the study was to demonstrate, by three-phase bone scintigraphy, radionuclide uptake at the site of defects in long bones filled with the non-resorbable bioactive glass-ceramic material BAS-0 at a long follow-up.MATERIALTwenty patients, 14 men and 6 women, operated on between 1990 and 2000 for benign bone tumors or tumor-like lesions localized in the femur, tibia or humerus were comprised in the study. Their average age at the time of operation was 14 years (range, 8 to 24). The diagnoses based on histological examination included juvenile bone cysts in 11, aneurysmal bone cyst in five, non-ossifying fibroma...

PURPOSE OF THE STUDYThe aim of the study was to analyze primary malignang tumors and tumor-like lesions of long bones, in relation to their localization, characteristics and distribution in age groups, in children and young adults, and to assess the role of radiography and magnetic resonance imaging (MRI) in their diagnosis.MATERIALSixty-four patients, aged between 3 and 20 years, who were referred to us with the diagnosis of a suspected malignant long-bone tumor of osseous or cartilage origin in the period from 2000 to 2004 were included in the study.METHODSPlain radiography and MRI were carried out on the same day. For MRI, the...

Results of Acetabular Reconstruction with Solid Bone Graft in Primary and Revision Hip ArthroplastyOriginal papers

P. ŽOFKA

Acta Chir Orthop Traumatol Cech. 2006; 73(3):190-196 | DOI: 10.55095/achot2006/027  

PURPOSE OF THE STUDYTo evaluate the results of acetabular reconstruction in total hip replacement and to compare them in view of the use of autologous or allogenic solid bone grafts.MATERIAL AND METHODSThe author evaluates a group of 48 total hip replacements carried out in the years 1990-1999, in which solid bone graft was used for reconstruction of an insufficient acetabulum. In 25 hips, the patient's own femoral head was used in primary surgery and, in 23 hips, a frozen femoral head from a tissue bank was used in revision arthroplasty. Most of the acetabular components used in this study were cemented. The patients were evaluated at...

Medial Opening-Wedge High Tibial Valgus Osteotomy, Using a Stable TomoFix Plate, in Genu Varum Arthritis: Surgical TechniqueIn-service-training

D. HORÁČEK, O. ČECH, M. WEISSINGER

Acta Chir Orthop Traumatol Cech. 2006; 73(3):197-204 | DOI: 10.55095/achot2006/028  

The authors present the technique of high tibial correction osteotomy by the medial opening procedure, with the use of an angle-stable TomoFix plate. The prerequisite for a long-term good outcome of corrective osteotomy in genu varum is to achieve limb alignment permitting transfer of weight-bearing from the affected medial compartment to the healthy lateral compartment of the knee. The development of implants that maintain a stable angle has facilitated corrective osteotomy with an opening wedge on the medial side of the proximal tibia. These implants provide stable fixation even when a high correction of the mechanical axis is needed. The authors...
