We wanted to verify the validity of the treatment of vertebroplasty and kyphoplasty to failure of the anterior column of the thoracic and lumbar spine.

Since 2002, 39 procedures of vertebroplasties and kypholasties were performed to 36 patients.

Most of the procedures were done because of painful ostoporotic fractures. 4 were because of metastasis, 2 hemangiomas of the vertebral body. 2 multiple myeloma. One Paget disease of bone.

In cases of multiple osteoporotic fractures, decision was made based on clinical Findings and bone scan.

Results were encouraging: 31 patients reported of improvement of pain. Analyzing Visual Analogue Score, alleviation was recorded immediately after surgery.

Few complications were registered: 2 patients underwent further surgery because of radiating pain. In two patients malpositioning of the Vertebral Body Reconstraction was seen. One patient had osteomyelitis of the vertebral body. 2 cement leakage were seen.

Vertebroplasty and kyphoplasty are good solutions for the treatment of failure of the anterior column in the thoracic and lumbar spine. Accurate patients election should be done in order to detect patients with spinal stenosis that will respond negatively to this treatment.

Purpose: Total knee arthroplasty has been established as a reliable treatment modality for advanced gonarthrosis. Satisfactory outcome depends on restoration of the neutral alignment of the leg. Our study evaluates whether computer-assisted navigated knee arthroplasty achieves a more accurate knee alignment.

Materials and Methods: In a prospective study two groups of 24 patients undergoing TKA had operations using either a computer-assisted navigation system or a conventional technique. Limb alignment and component orientation were determined on post-operative coronal and lateral X-rays.

Results: In our study the post operative axis of the thumb was significantly better in the computer-assisted group (94%, within ±3° varus/valgus) compared with the conventional group (82%, within ±3° varus/valgus). A significantly better orientation of the femoral and the tibial components was achieved in the computed-assisted navigated group.

Conclusions: Computer-assisted navigated TKA gives better correction of leg alignment and components orientation as we saw in the computer-assisted navigated group. Potential benefits in the long-term outcome and functional improvement require further investigation.
