Analysis of Results After Surgical Application of Bone Marrow Aspirate Stem Cell Concentrate in the Treatment of Avascular Necrosis of the Femoral Head.

: Avascular necrosis or osteonecrosis of the femoral head is defined as a pathological process that results in a critical reduction in the blood supply to the hip head with increased intraosseous pressure. Avascular necrosis is a multifactorial disease. The treatment used so far consists of transosseous decompression of the femoral head and is the most commonly used method in the early stages of osteonecrosis.

Analysis of the results of implantation of total hip endoprothesis in severe dysplastic coxarthrosis.

Background: The aim of this study is to affirm the importance of operative treatment of severe dysplastic coxarthrosis through analysis of the results of implantation of total cementless endoprothesis in patients with DDH Crowe types III and IV.

Patients And Methods: This retrospective study involved 28 patients (30 hips) with dysplastic coxarthrosis, in whom an implantation of cementless total hip endoprothesis was performed at the University Clinic for Orthopaedic Surgery in Skopje. In 26 of the patients the involvement was unilateral and in two patients it was bilateral.

Analysis of radiographic bone parameters throughout the surgical lengthening and deformity correction of extremities.

Background: Radiographic examination of extremities in surgical lengthening and/or correction of deformities is of crucial importance for the assessment of new bone formation. The purpose of this study is to confirm the diagnostic value of radiography in precise detection of bone parameters in various lengthening or correction stages in patients treated by limb-lengthening and deformity correction.

Patients And Methods: 50 patients were treated by the Ilizarov method of limb lengthening or deformity correction at the University Orthopaedic Surgery Clinic in Skopje, and analysed over the period from 2006 to 2012.
