Pseudotumor as a Complication of Total Hip Replacement.

Total hip arthroplasty with metal-on-metal bearing is associated with specific complications: local delayed hypersensitivity reaction (ALVAL) to metal particles, osteolysis and the development of pseudotumors. This process results from the low resistance of the metal bearing to abrasion and corrosion, which causes the release of metal ions into the surrounding tissues. This paper presents the case of a 54-year-old man who required revision surgery due to aseptic loosening of the endoprosthesis with a ceramic (TiN)-on-metal bearing.

Chronic, Neglected Medial Subtalar Dislocation with Associated Talar and Calcaneal Fractures. A Case Report.

Subtalar dislocation is a very rare injury that accounts for just approximately 1% of traumatic dislocations. Stan-dard treatment in acute subtalar dislocations is immediate closed reduction and cast immobilization. Early reduction is of key importance and allows avoiding further damage to soft tissues, nerves and blood vessels.

Factors Influencing Treatment of Proximal Femoral Fractures.

Background: Orthopaedics and traumatology departments are dominated by patients with proximal femoral fractures, who represent 20-30% of all patients treated there. The aim of this study was identification and evaluation of factors influencing treatment of proximal femoral fractures.

Material And Methods: Between 2008 and 2015, we treated 424 femoral neck fractures and 442 trochanteric fractures in patients over 40 y/o.

Laceration of abdominal aorta by a fragment of fractured L2 vertebral body after a low-energy injury: a case report and review of literature.

Study Design: A rare case of direct injury to the wall of abdominal aorta caused by a displaced fracture of the L2 vertebral body resulting from a low-energy injury. Potential injury mechanism and predisposing factors are discussed along with a review of literature pertaining to the subject.

Objective: To describe a unique case of direct aortic wall injury caused by a displaced vertebral body fracture.

Neglected, developmental hip dislocation treated with external iliofemoral distraction, open reduction, and pelvic osteotomy.

Between 1995 and 2003, we operated upon 18 children with 20 hips involved, aged 5-11 years (average: 7.5 years) suffering from an inveterate high developmental dislocation of the hip joint. An average follow-up period of our middle-term study was 51 months (range: 34-96 months).

[Solid focal lesions in the lungs as first sign of hypereosinophilic syndrome].

The paper introduces a case of 50 years old women who was diagnosed because of solid focal lesions in the lungs with coexist hypereosinophilia in blood smear. During diagnostics neoplastic and infectious diseases were excluded. In the meanwhile secondary causes of hypereosinophilia was not found.

The application of bone cement to fill the surgical defect after resection of a giant-cell tumor: A case report.

Background. A case of a large bone defect treated with bone cement filler is discussed, and the usefulness and advantages of this treatment method are assessed. Case report.

Selected problems in the bone union of complicated diaphyseal fractures treated with interlocking nail.

Background. This article discusses the effectiveness and technical problems encountered in the union of complications of diaphyseal fractures treated with interlocking nail. Material and methods.

[Chlamydia pneumoniae antibodies and other atherosclerosis risk factors in haemodialysed patients. Preliminary report].

Nowadays, it is considered that viral or bacterial infections can influence atherosclerosis development rate. One of them is infection by Chlamydia pneumoniae. The aim of the study was to assess the occurrence of anti-Chlamydia pneumoniae antibodies (AChPA) and their relationship with biochemical and clinical atherosclerosis risk factors in haemodialysed patients.

[Inferior subluxation of humerus after surgery of fractures of proximal humerus].

Posttraumatic inferior subluxation of the humerus can be a possible cause of nerve injury and is therefore an alarming symptom. Etiology and frequency of subluxation after surgery of fractures of proximal humerus in group of 53 patients, including 4 cases of nerve injuries were studied. X-rays performed during treatment of this patients were analyzed.
