The aim of this paper was to assess the results of treatment of pesudoarthrosis of the tibia and femur with reamed interlocked intramedullary nailing. A group of 17 patients with pseudoarthrosis of long bones were treated. Pseudoarthrosis were located in 10 cases in the tibia and in 7 cases in the femur. In the analysed group there were 14 male and 3 female patients (average age: 48 years). All patients were treated by locked intramedullary nailing. Complete bone union was observed in 15 cases, 1 case is still under observation (radiological signs of bone union are already evident) and in 1 case treatment failed to resolve the pseudoarthrosis. Intramedullary interlocking nailing in the treatment of long bone pseudoarthrosis give very good stability and creates very good conditions for blood vessel penetration between the bone fragments. The reaming procedure yields biologically active material that accelerates the bone union process.

The aim of this paper was to assess early results of revision arthroplasty in aseptic loosening of cemented sockets. A group of 67 patients (53 females and 14 males) age ranging from 47 to 78 years (average: 72 years) who underwent revision arthroplasty because of aseptic loosening of cemented sockets. Early surgical treatment can spare the patient from a risky procedure and lead to better end results. In cases with massive bone destruction of the pelvis good results can be achieved by using bone grafts and anti-protrusion cages.
