Percutaneous vertebroplasty is an effective procedure for the treatment of osteoporotic vertebral compression fractures, spinal metastasis and other pathologic spinal diseases. However, there has been no mention in the relevant literature of the use of percutaneous vertebroplasty for the treatment of spinal pseudarthrosis in ankylosing sponyloarthritis. A 58-year-old male with a long standing ankylosing spondylitis presented with increasing, intolerable and non-intractable back pain. There was a 16- month-old history of a non-significant minor fall. Various radiological imaging technicques showed spinal pseudarthrosis with extensive discovertebral destruction and fracture of the posterior elements at the level T11–T12. Under local anaesthesia, and through a transpedicular approach with the guidance of CT, the cannula of a large bore needle was introduced into the level of spinal pseudarthrosis. Bone cement was then instilled into the affected spinal level. Results were documented by spiral CT and with sagittal reconstructions. Extraosseous cement leakage was seen at the puncture site of the vertebra and in the epidural veins and the paravertebral vessels. However, the patient did not present any immediate or late neurological and systemic complications. Percutaneous vertebroplasty of spinal pseudarthrosis in patients with ankylosing spondylitis is an effective procedure for stabilization of the affected spine segments and pain management.

Introduction: Patellar tendon is one of the main donor sites for graft. Postoperatively, during the healing procedure there are changes, which we recorded and combined them with the clinical image respectively.

Material and Methods: During the period 1998–2001 in Sports Injury Unit, we operated for Anterior Cruciate Ligament insufficiency with autologous Bone Patellar Tendon Bone (BPTB) graft 265 patients. We used autologous BPTB graft from the middle third. We got near the two parts after taking the graft and we sewed very well the peritendon fascia. All patients, with few differentiations, followed the same rehabilitation program.

Seventy -seven of them (44 men and 33 women ranging from 17 to 44 years -mean: 24,3 years), were imaged postoperative with MRI at specific intervals from the operation between 3–36 months. In the same time we checked the patients clinically.

Results: No one study can answer which is the exact time of satisfying or complete healing. Our study shows elements of scar tissue in the middle third of patellar tendon which is decreasing given time. After the 12th month, the proportion between healthy and scar tissue changes and healthy tissue become dominant. But in some cases scar is still existing even after 36 months. The clinical problems such as anterior knee pain are not existed after the 8th postoperative month.

Conclusion: In conclusion, we can say that “regeneration” and healing of patellar tendon occurs mainly during the first postoperative year, but it doesn’t stop after this time. So, we couldn’t recommend this donor site for revision reconstruction before the completion of one year postoperatively.
