During the period 2004–2009, 35 children were admitted to the emergency department,(24 males:11 females), aged 3–14 years old,(MEAN 8,45 years), with supracondylar humeral fractures (33 extension type and 2 flexion type). All fractures were closed and result of sports injuries or games and were treated with closed reduction under general anesthesia and percutaneous k-w fixation. The postoperative follow-up lasted from 6 months to 4 years. The Bauman’s angle was evaluated postoperatively on the operated and normal elbow and was 76, 6 ±1° and 74, 7 ±0, 6°. According to Flynn’s criteria the functional outcome was excellent in 29 cases. In 6 cases where the Bauman’s angle was greater than 10–15° there has been observed varus deformity (4 cases), valgus deformity (1 case), and flexion deficit (1 case). The percutaneous k-w fixation and preservation of Bauman’s angle with carrying angle too, on supracondylar humeral fractures on children is a safe solution to avoid future complications.
To estimate the outcomes after posterior dynamic stabilization in situ with Dynesys (Zimmer Spine, Minneapolis, MN) for treatment of symptomatic spinal stenosis and degenerative spondylolisthesis in long-term follow-up. 28 patients(mean age 73 years old) with symptomatic spinal stenosis and spondylolisthesis underwent inter-laminar decompression and stabilization with Dynesys. Patients were evaluated clinically and radiologically after a follow-up from 6 months to 4 years. Pain on VAS and walking distance improved significantly at less than 2 years and remained unchanged at 4 years follow-up. Radiographically, spondylolisthesis did not progress and the motion segments remained stable. 2 patients showed screw-loosening at 1 year follow-up and underwent revision. Overall, patient satisfaction remained high as 93% and would undergo the same procedure again. In elderly patients with spinal stenosis and degenerative spondylolisthesis, decompression and dynamic stabilization lead to excellent clinical and radiologic results. It maintains enough stability to prevent progression of spondylolisthesis. Because no bone grafting is necessary, donor site morbidity, which is one of the main drawbacks of fusion is eliminated
