Suction/irrigation for deep wound infection after spinal instrumentation: a case study.
Deep wound infection after spinal instrumentation is a serious complication that is difficult to treat without removing the instruments and bone graft. Debridement and suction/irrigation is an effective method of treatment in these cases. ⋯ Four patients with early post-operative infection were cured by this method without removing the instruments and bone graft, and two patients with delayed post-operative infection were cured by this method with instrument removal. Debridement and suction/irrigation is a useful method of treatment for both groups of deep wound infection and gives good results when performed soon after infection onset together with additional antibiotic therapy.

Little is known about the influence of high-performance training on the bone quality of the lumbar spine, in particular, the effects on bone mineral density (BMD) in athletes with high weight-bearing demands on the spine. Measurements were therefore performed in internationally top-ranked high-performance athletes of different disciplines (weight lifters, boxers, and endurance-cyclists). The measurements were carried out by dual-energy X-ray absorptiometry, and the results compared with the measurements of 21 age-matched male controls. ⋯ The results show that training program stressing axial loads of the skeleton may lead to a significant increase of BMD in the lumbar spine of young individuals. Other authors' findings that the BMD of endurance athletes may decrease are confirmed. Nevertheless the 10% BMD loss of cyclists was surprisingly high.

The segmental effect of Cotrel-Dubousset instrumentation (CDI) on the spine and thoracic cage was investigated in 38 patients with adolescent idiopathic scoliosis by preoperative and postoperative postero-anterior and lateral radiographs and computed tomography from T1 to S1. Mean Cobb angle decreased by 67%. The T5-T12 kyphosis in the hypokyphotic patients increased on average by 8.4 degrees (P < 0.001). ⋯ However, no correlation was found between flexibility index and reduction of RHi at the apex level. Vertebral derotation did not correlate with reduction in RHi at any level. The study shows that CDI results in a postoperative three-dimensional improvement of the spine and a limited improvement of the thoracic cage, with no tendency towards a worsened deformity at any level within or outside the instrumentation.

We report on two children with tuberculosis of the craniocervical junction. Atlantoaxial instability was evident in both patients due to the destruction of the dens and the atlantoaxial ligaments. ⋯ Despite anti-tuberculosis treatment and immobilization, atlantoaxial instability was evident on flexion/extension views. Successful fusion of C1 and C2 was performed in both patients.

Review Case Reports
Urinary bladder dysfunction following anterior lumbosacral spine fusion: case report and review of the literature.
A 34-year-old woman suffering from chronic degenerative low back pain involving L5-S1 disc space, refractory to conservative treatment, underwent spinal fusion. A combined instrumented posterolateral, followed by anterior, interbody allograft fusion through a left retroperitoneal approach was performed. Postoperatively, the patient was unable to evacuate her bladder and control her micturition. ⋯ A self-catheterisation regime was instituted with a diagnosis of parasympathetic nerve injury during the anterior spinal fusion. After a period of 3 months, the patient regained control of urination. We report this case to highlight the importance of protecting the parasympathetic presacral nerve during L5-S1 anterior interbody fusion, as injury to this nerve affects urinary evacuation.
