BACKGROUND

As life expectancy in the population rises, osteoporotic fractures are seen most frequently in the vertebral column. Percutaneous kyphoplasty is increasingly used for pain reduction and stabilization in these patients, but the efficacy, cost-effectiveness, and safety of the procedure remain uncertain.

BACKGROUND

Osteoporosis with subsequent osteoporotic vertebral compression fractures is an increasingly important disease due not only to its significant economic impact but also to the increasing age of our population. Pain reduction and stabilization are of primary importance with osteoporotic vertebral compression fractures.

To compare the early functional and clinical results, between single (SB) and double-bundle (DB) of Anterior Cruciate Ligament (ACL) reconstruction with hamstrings (HS).

Thirty-six patients from 17 to 36 years old (average age 23), 22 ♂ and 14 ♀, from January 2006 to May 2008, were randomly allocated for ACL reconstruction with HS (SB – DB). Eighteen patients underwent a 4-stranded SB reconstruction (group A) and the remaining 18 underwent an anatomic, 2-stranded DB ACL reconstruction with 2 tibial and 2 femoral tunnel technique (group B), by using the Smith & Nephew instrumentation system. The follow-up was from 8 to 22 months (average 16 months) for both groups and included clinical evaluation (pivot-shift test, anterior laxity test with KT-1000 arthrometer and Lysholm knee score) and radiographs.

There were no statistically significant difference in the results between the 2 groups with regard to the pivot-shift test and the Lysholm score (SB: mean 91, DB: mean 89) (Mann-Whitney test, T-test). The anterior laxity was not significantly different between group A (mean, 2.2mm) and group B (mean, 0.9mm), according to KT-1000 measurements. Rotational stability, as evaluated by pivot-shift test, was better in group B than in group A, but statistical analysis showed no significant difference. The average operation time was longer in DB (110 min) compared to SB (80 min). There were no infections, though one patient of each group was found to be complicated with fixed flexion and extension lag > 5°; and underwent arthroscopic lysis.

Our study shows no statistically significant advantage of DB versus SB ACL reconstruction, concerning the clinical evaluations and the complications

Objective: Effectiveness and safety of Balloon Kyphoplasty as a method of treatment for osteoporotic vertebral fractures of the thoracolumbar spine.

Materials and Methods: From January 2003 to December 2008, 102 patients (27 males and 75 females), from 56 to 82 years old (mean age 72) were treated with balloon kyphoplasty procedures for 156 osteoporotic vertebral fractures of the thoracic or lumbar spine, in a mean follow up of 24 months (6 to 45 months). The patients had progressive and painful compression fractures more than 2 months. All fractures were analyzed for improvement in sagittal alignment (Cobb angle, kyphotic angle, sagittal index, vertebral height). The patients were evaluated using the visual analog scale (VAS) and the Oswestry Disability Score. Radiographs were performed postoperatively, and at 1, 3, 6, and 12 months.

Results: The score according to pain, the patient’s ability to ambulate independently and without difficulty, and the need for medications improved significantly (P < 0.001) after kyphoplasty. Vertebral height significantly increased at all postoperative intervals, with ≥10% height increases in 88% of fractures. Morphometric height ratios for treated fractures also significantly increased. There were no severe kyphoplasty-related complications, such as neurological defects, cement leakage or narrowing of the spinal canal whereas additional fractures occurred at the adjacent vertebrae at a rate of 10%.

Conclusions: Kyphoplasty provided a safe and effective treatment for pain and disability in patients with vertebral compression fractures due to osteoporosis.

The aim of our study was to examine the outcome of ACL reconstruction by using four strand hamstring tendon autografts.

Material and Methods: the study included 44 patients (29 males,15 females;mean age 26;18–45 years). The diagnosis was based on clinical examination and imaging techniques. The operation was performed arthroscopically 4–62 weeks after the injury. The tendon was fixed in the tibia with an interference screw and in the femur with three different methods cross pin in 16 cases, transfix pin in 11 cases and Endo button in 17 cases.

Results: The mean follow up was 28 months (12–42). The mean Lysholm score was improved from 35–65 (mean 49) preoperativelly to 55–100 postoperativelly (mean 88).

5 patients had laxity > 3mm when compared to the healthy knee by using the KT-1000 arhthrometric testing. 2 of the latter patients complained of a feeling of knee joint instability which occurred due to inaccurate positioning of the femoral tunnel. In 2 cases the transfix pins were displaced and removed on the 4th and 15th post-operative month.

The tunnel expansion was measured by an X-Ray or a CT scan. The tibial tunnel expansion was 0–2.5mm (mean 1.2) or 18% and the femoral tunnel expansion was 0–3 mm (mean 1.4) or 26%. 8 patients reported mild pain which did not restrict their activities. A 5 degree loss of extension was noticed in one patient who continues physiotherapy.

28 of the above patients suffered also from a meniscal injury that was managed arthroscopically.

Conclusion: ACL reconstruction by using four strand hamstring tendon autografts is safe, highly successful with very few complications when proper graft preparation and accurate tunnel placement is achieved.

Purpose: To present/evaluate the results of ‘intramedullary hip screw’ (IMHS) for treatment of subtrochanteric fractures of the hip.

Materials and Methods: Between 2003–2005 fifty four (54) patients aged 62–92 years old (average: 77,3 yrs) with subtrochanteric fractures of the hip were treated in our department with intramedullary hip screw (IMHS). Thirty one (31) patients were women and twenty three (23) were men. Thirty (30) fractures were located in the right hip and the remaining twenty four (24) in the left one. All patients were operated by the same surgical team –within 3 days from injury in the 86% of the cases. The duration of the procedure was between 55–75 minutes. Post-op, the patients were mobilized early with -at least–partial weight bearing and they were followed-up -clinically and radiologicallly for 7–30 months.

Results: 85% of the fractures were united within 14 weeks uneventfully. In seven cases, bone grafts were used. Three (3) cases of superficial wound inflammation and two case of haematoma were noticed. All above cases were treated successfully. Neither femur’s fractures (near or distal to the tip of IMHS) nor failure of implants were noticed. The 75% of patients achieved the pre-op status of rehabilitation.

Conclusions: The results of this study show that ‘intramedullary hip screw’ (IMHS) seems to be a reliable treatment for the subtrochanteric fractures of the hip; and it could be considered as one of treatment of choice for them.
