Presently, there are multiple nonoperative techniques a surgeon can use to alleviate the pain of an osteoarthritic joint including: oral medications, physical therapy, injections and off-loading knee braces. The objective of this study was to analyze subjects under in vivo, dynamic conditions using fluoroscopy to determine if off-loading knee braces actually separate the femoral condyle from the tibial plateau during the mid-stance and heel-strike phases of gait. Forty subjects with substantial unicompartmental osteoarthritis were studied under fluoroscopic surveillance in the frontal plane while performing normal gait on a treadmill. The subjects...

[Results of the treatment of hip joint dislocation by an over head traction and hanausek biomechanical device.].

Acta Chir Orthop Traumatol Cech. 1999; 66(6):328-335

The basic material for the evaluation of the results of a conservative treatment of DDH was a group of children at Ist Orthopaedic Clinic in the period of 1984-1994. In total 80 children were treated there, of this 69 girls and 11 boys. The right hip joint was affected 25times, the left hip joint 41 times, bilateral dislocation occured 14times.The evaluation covered in total 94 hip joints. In parents congenital dysplasia of hip joint occurred in case of 23 children, i. e. 28,5 %. The treatment followed immediately the diagnosis of the dislocation, on average at the age of 3.3 months of the child. All children were hospitalized with their mothers and...

[Solution of Intertrochanteric Fractures of Proximal Femur by 130 degrees Angled Blade Plate - Longterm Results.].

Acta Chir Orthop Traumatol Cech. 1999; 66(6):336-341

Authors summarize their longterm outcomes of the use of 130 degrees angled blade plate in intertrochanteric fractures. The group comprises 110 patients operated on by this technique in the period of 1988-1997. The analysis of the results has proved that this technique was justified in stable fracture classification according to AO/ASIF - A1.1 A1.2. In other fractures A1.3 A2.1 A2.2 A2.3 there occurs after 6 months a varus position and in extreme cases the internal fixation fails. In the second part of the article the authors inform about the results in a group of 24 patients 3 to 6 years after operation. The patients have been subdivided into two groups...

[Comparison of the treatment of juvenile bone cysts by corticoids and bone grafting.].

Acta Chir Orthop Traumatol Cech. 1999; 66(6):342-349

Juvenile bone cysts are frequent affections. Their treatment develops in the direction of the application of less invasive methods. The authors treated 43 patients with this diagnosis in the period of six years. The aim of the article is to specify the criteria for the indication of two most frequently used methods of treatment of juvenile bone cysts, namely. a)percutaneous instillation of methylprednisone acetate (MPA); b)surgical curettage and bone grafting of the cyst by an autograft or allograft. They state that significant for the prognosis of the juvenile bone cyst are: 1. the age of the patient, 2. activity or latency of the juvenile bone cyst,...

[Os Odontoideum - Post-traumatic Instability of C1-2.].

J Stulík, M Krbec

Acta Chir Orthop Traumatol Cech. 1999; 66(6):356-361

The case report presents a patient (male, 21 years old) who had a car accident and sustained an injury of upper cervical spine. X-ray examinations showed instability of C1-2 segment with a simultaneous os odontoideum. Subsequently CT and MRI examinations were performed to specify the anatomical relations. The patient had only a neurological lesion revealed by the examination by motor evoked potentials (MEP). The metric measurements on standard and functional radiographs showed a minimal sagittal dimension (Dmin) of 13 mm, the distance between os odontoideum and C1 arch (Datl) was 24 mm, the instability index after Penning was 20 mm, the distance between...

[Swivel luxácia Chopartovho kĺbu.].

Acta Chir Orthop Traumatol Cech. 1999; 66(6):362-366

The authors report a special type of Chopart dislocation named as swivel dislocation or tarsal rotation. This injury is characterized by dislocation of the talonavicular joint but the calcaneocuboid joint remains intact.The foot creates a typical rotational movement but it does not evert or invert. The axis of rotation is interosseous talo-calcaneal ligament, which remains intact. In the reported case the medial swivel dislocation is present in combination with fracture-dislocation of the ankle joint with diaphyseal fracture of fibula and segmental fracture of tibia in the same extremity in multiple injury patient. The typical characteristic and method...
