[Cementless socket fixation based on the "press-fit" concept in total hip joint arthroplasty].

E W Morscher, K H Widmer, H Bereiter, R Elke, R Schenk

Acta Chir Orthop Traumatol Cech. 2002; 69(1):8-15

PURPOSE OF THE STUDY: The key problem of implant fixation in THR is stress distribution, i.e. load transmission between bone and implant. The closer the load transfer is to the original physiological situation, the easier the adaptation of the periprosthetic bone to the new biomechanical conditions after implantation of the cup and the safer is its longlasting fixation. The aims of the studies were 1) to get information about the physiological load transfer in the normal hip joint, 2) to get information about the load transfer between acetabulum and acetabular sockets and vice versa, 3) to measure the periacetabular pelvic bone deformation as the stimulator...

Osseous integration of hydroxyapatite grafts in metaphyseal bone defects of the proximal tibia (CT-study).

C Khodadadyan-Klostermann, T Liebig, I Melcher, M Raschke, N P Haas

Acta Chir Orthop Traumatol Cech. 2002; 69(1):16-21

PURPOSE OF THE STUDY: The purpose of the study was the examination of the osseous integration of hydroxyapatite grafts used for the filling of metaphyseal bone defects in tibia head fractures.MATERIAL: Four patients with lateral tibia plateau fractures AO-type B3 (12) were included in the study. Patients were treated by arthroscopically assisted reduction and percutaneous screw fixation. The metaphyseal bone defects were filled with prepared solid hydroxyapatite graft blocks (Endobon Fa. Merk Darmstadt, Germany). In all of the patients a CT study for the osseous integration of hydroxyapatite grafts used for the filling of metaphyseal bone defects...

[Osteosynthesis of trochanteric fractures using proximal femoral nails].

P Dousa, J Bartonícek, D Jehlicka, J Skála-Rosenbaum

Acta Chir Orthop Traumatol Cech. 2002; 69(1):22-30

PURPOSE OF THE STUDY: Presentation of the existing experience in the use of Proximal Femoral Nail Synthes (PFN) in trochanteric fractures.MATERIAL: A prospective study evaluating a group of 41 patients, 12 men and 29 women, average age 68 years (range 21-93 years) operated on between September 1997 and March 2001 by means of PFN. The group comprised 11 unstable peritrochanteric fractures (31-A2), 26 high subtrochanteric fractures (31-A3), 3 low subtrochanteric fractures and 1 pathological fracture.METHOD: Monitored were first of all preoperative and post-operative complications and final results.RESULTS: The average duration of surgery...

[Fractures of the femoral neck in children: complications and their treatment].

P Chládek, T Trc

Acta Chir Orthop Traumatol Cech. 2002; 69(1):31-34

PURPOSE OF THE STUDY: Fractures of femoral neck in children are rare skeletal injuries which are, however, associated with a high percentage of complications. The aim of the retrospective study is to evaluate a group of patients in relation to the incidence of individual complications and demonstrate the methods used for the solution of these complications.MATERIAL: Twenty patients with fractures of femoral neck (average age 10 years 5 months) were treated at the Department of the authors in the period between 1983 and 1997. Of this 18 patients were operated on (most frequently used was internal fixation by 2 cancellous screws). In the given period...

[Are screws in anterior cervical fusion with bicortical fixation truly inserted bicortically? Retrospective study].

P Barsa, P Suchomel, P Buchvald, R Lukás, E Vanícková

Acta Chir Orthop Traumatol Cech. 2002; 69(1):35-38

PURPOSE OF THE STUDY: To examine the exact position of screws in anterior cervical fusion that were intended to be bicortically anchored at the time of surgery.MATERIAL: A randomly selected, representative sample (26) of our patient series undergoing anterior cervical fusion with bicortical screw fixation (250) during period of 1993-1999 is reviewed in this study with respect to an exact position of the tips of the screws to the posterior vertebral cortex. A total of 109 screws were assessed.METHODS: The position of 109 screws was assessed using an axial CT scan. On the basis of the distance of the screw tip from the posterior cortex of the...

[Mortality in patients with proximal femoral fractures during the first year after the injury].

V Dzupa, J Bartonícek, J Skála-Rosenbaum, V Príkazský

Acta Chir Orthop Traumatol Cech. 2002; 69(1):39-44

PURPOSE OF THE STUDY: The authors present an overview of mortality of patients with proximal femur fractures treated at the authors' Department in 1997 in dependence on different factors relating to the preinjury condition and the treatment itself. The aim of the work was to determine the impact of these factors on the risk of mortality and compare the findings with the data published by other authors dealing with the same issue.MATERIAL: In the given year 244 patients with 248 proximal femur fractures, 58 men (24%), 186 women (76%), average age 77 years were treated. There were 115 (47%) fractures of femoral neck, 117 (47%) pertrochanteric fractures...

[Personal experience with the basal wedge closed osteotomy of the first metatarsus in hallux valgus].

M Lutonský, P Sponer

Acta Chir Orthop Traumatol Cech. 2002; 69(1):45-48

PURPOSE OF THE STUDY: The authors present their philosophy of the surgical treatment of metatarsus primus varus by oblique basal closed osteotomy of 1st metatarsal, evaluate and generalize the results achieved also with regard to the age of patients.MATERIAL: The evaluation covers a group of patients operated on for the mentioned static defect since 1995 with a minimal interval of 12 months after the surgery. From this general group a subgroup has been subsequently singled out of children and adolescents up to the age of 18. The general group included 24 patients in which 31 surgeries were performed. The subgroup of children and adolescents comprised...

[Atlanto-axial rotation dislocation (case report)].

J Stulík, M Krbec

Acta Chir Orthop Traumatol Cech. 2002; 69(1):49-53

The authors present a female patient 45 years old, who had a car accident as a driver of a passenger car. Her car was hit from the left side by another car and the women hurt her head, neck and left shoulder. Due to pain in the region of the head and neck she was taken to the respective surgical out-patient department where they diagnosed the concussion of the brain of II degree and distortion of the cervical spine. The patient was treated conservatively by bed rest with the cervical spine fixed in the soft Schanz collar. After ten days she was discharged from the hospital and further followed up by a neurologist in the out-patient department. She...
