A novel approach to surgical treatment of adolescent idiopathic scoliosis in skeletally immature patients.

Purpose: Describe the surgical technique and experience using the LSZ growing system in skeletally immature patients for two-stage surgical treatment of adolescent idiopathic scoliosis (AIS).

Methods: Eleven skeletally immature patients who underwent two-stage surgical treatment of AIS in our center were retrospectively analyzed. Patients initially treated with the LSZ growing system were observed for an average of 40.

Two-stage treatment of idiopathic scoliosis using the LSZ growing system with a 10-year follow-up: a case report.

A clinical case of an 11-year-old patient with idiopathic scoliosis treatment using the LSZ growing system. The main thoracic curve was 88°, with a lumbar curve of 52°. The patient was at Risser stage 3.

[Thrombotic events in patients with hemophilia].

The paper describes 4 clinical cases of thrombotic events (pulmonary embolism, deep vein thrombophlebitis, acute myocardial infarction, ischemic stroke) that have occurred in patients with hemophilia. It discusses the possible causes of their development and methods for their prevention and treatment. Controlled natural hypocoagulation, in which the dose of an administered deficient factor decreases to such an extent that in order to maintain the safe level of hypocoagulation (plasma factor activity is 15-20%; activated partial thromboplastin time is 1.

Metal concentrations in the blood and tissues after implantation of titanium growth guidance sliding instrumentation.

Background: Growth guidance sliding treatment devices, such as Shilla (Medtronic, Minneapolis, MN USA) or LSZ-4D (CONMET, Moscow, Russia), used for the treatment of scoliosis in children who have high growth potential have unlocked fixtures that allow rods to slide during growth of the spine, which avoids periodical extensions. However, the probability of clinical complications associated with metallosis after implantation of such devices is poorly understood. The content of metal ions in the blood and tissues of pediatric patients treated for scoliosis using fusionless growth guidance sliding instrumentation has not yet been investigated.

Experience of recombinant activated factor VII usage during surgery in patients with haemophilia with inhibitors.

Inhibitor development is one of the most challenging complications of haemophilia management. Haemostatic control in patients with haemophilia with inhibitors can be difficult, and is especially risky in those undergoing surgical interventions. Most haemophilia patients with inhibitors suffer from chronic joint disease requiring surgical correction due to recurrent bleeding episodes.

[Therapy of acute massive blood loss in a hemophilic patient: case report].

A case is reported of management of massive intraoperative blood loss in a male patient with severe hemophilia. Extirpation of hip pseudotumor with one-stage osteosynthesis with an intramedullary joint-pin in a 43 year old male patient was accompanied with 7.5 l blood loss.
