[The history of Metasul].

Acta Chir Orthop Traumatol Cech. 2002; 69(5):277-284

The first generation, metal-on-metal articulation from cobalt-chromium-molybdenum alloy produced by Sulzer Ltd. has been in use for 40 years. Former drawbacks concerning geometry, tolerance or metallurgy have been eliminated in the second generation METASUL components used since 1988. These are also free of disadvantages, such as potential fracture, shown by other hard-on-hard bearing couples. For 14 years now METASUL components have not been responsible for any repeat operation due to loosening. Both clinical and experimental outcomes show that yearly wear has been negligible (in the order of microns) and this allows us to expect the metal-on-metal...

[A less invasive retropleural-retroperitoneal approach to the thoraco-lumbar spine].

J Kocis, P Wendsche, P Visna, V Muzík

Acta Chir Orthop Traumatol Cech. 2002; 69(5):285-287

UNLABELLED: Authors describe the technique of anterior less invasive approach to the treatment of thoracolumbar spine. The advantage of the mentioned approach is the treatment of the anterior spinal column without opening the thoracic cavity.MATERIAL: In the period between 1996-2000 the described method was used in 46 patients. The average age of patients was 49 years (range, 22 to 67 years). There were 30 men and 16 women. Most frequently affected was L1-fractures in 29 patients, Th12 was handled in 16 patients and Th11 only in one case.METHOD: The surgical technique is based on the anterior approach to thoracolumbar spine without opening...

Acta Chir Orthop Traumatol Cech. 2002; 69(5):288-294

PURPOSE OF THE STUDY: The primary reduction and stabilization of all types of injury to the thoracolumbar spine is currently performed from the posterior approach by an internal, transpedicular fixator. The exceptions are type A fractures, according to the AO classification, that can primarily be treated from the anterior approach. The aim of the study was to assess the effect of BAS-O bioceramic granules, inserted by transpedicular approach, on the development of post-operative kyphosis of the segments injured.MATERIAL: Between 1997 and 2001 we treated anterior spinal column fractures, using bioceramic granules in combination with an internal...

[Use of bioactive glass ceramics in the treatment of tibial plateau fractures].

Acta Chir Orthop Traumatol Cech. 2002; 69(5):295-301

PURPOSE OF THE STUDY: The surgical treatment of proximal tibia fractures requires a reduction and fixation of the split condyle, elevation of the depressed interfragment of articular surface. The golden standard is the application of autogenous bone grafts for filling in the defect in the cancellous bone of the tibial condyle. Bioactive glass-ceramics material may be successfully used for the filling. Gass-ceramics BAS-O is biocompatible and bioactive and has also suitable mechanical properties and therefore it was used in combination with autogenous bone marrow in order to speed up osteogenesis.MATERIAL: The study covered 12 patients, 4 men and...

[Intra-articular treatment with Hyalgan in osteoarthrosis of the knee joint: experience in clinical practice in the Czech Republic].

K Pavelka, T Trc, K Karpas, R Moster, P Audy, L Hrazdíra, M Macák, P Sustek

Acta Chir Orthop Traumatol Cech. 2002; 69(5):302-307

PURPOSE OF THE STUDY: To evaluate safety and efficacy of intraarticular (IA) hyaluronic acid (HA; Hyalgan in current medical practice.MATERIAL AND METHODS: Multicenter, prospective, opened, observational study included 601 patients in 35 centers in Czech Republic. Patients had analgesics and NSAIDs on demand as rescue analgesia, but i. a. corticosteroids were not allowed. Patients received 1 series of 5 IA injectious of HA into one knee. Outcome measures were: pain at rest and on walking, patients global and assessment of therapy, Lequesne's index, consumption of NSAIDs. The patients were followed for 17 weeks (12 weeks after the last injection).RESULTS:...

[DHS (Dynamic Hip Screw) osteosynthesis in an atypical situation].

J Matĕjka

Acta Chir Orthop Traumatol Cech. 2002; 69(5):308-311

The author describes a spiral fracture of the distal femur with a fragmented zone that occurred in the place of the distal end of a splint applied because of the previous treatment of a subtrochanteric fractures by osteosynthesis. Atypical approach including a DHS implant was used to treat the spiral fracture. By literature search it was found that this therapy had not previously been described. Different options for stabilization of this fracture are discussed and it is concluded that, for this indication, the use of the DHS system was the most convenient. The author sets rules for the application of a DHS implant as follows: 1) the procedure should...

[Occult bone trauma detected by magnetic resonance imaging].

B Drugová, V Bumbálková

Acta Chir Orthop Traumatol Cech. 2002; 69(5):312-316

Authors deal with a case of a 23-year old women presented with a sport-related injury of the left knee joint. Initially seen in the surgical department, patient presented with pain, swelling, and decreased range of motion of the left knee. Conventional radiographs of the left knee showed no evidence of fracture or osseous abnormality, while the puncture of the joint proved haemarthros. One day later surgical examination demonstrated repeatedly pain and swelling of the left knee expanding to the proximal third of the leg. Repeated puncture exhibited haemorrhagic synovial fluid containing fat tissue, lipohaermarthos. With regard to the contradiction...
