Less invasive lumbopelvic stabilization of posterior pelvic ring instability: technique and preliminary results

Lumbopelvic distraction stabilization with (triangular osteosynthesis) or without additional iliosacral screw allows anatomic reduction of the posterior pelvic ring after severely displaced sacral fractures, correction or resection osteotomies of malunions, respectively, septic sacroiliitis and permits early weight bearing. However, this technique is complicated by wound necrosis or infection in up to 20% to 30%. We describe our experience with a less invasive technique.

The unstable painful shoulder (UPS) as a cause of pain from unrecognized anteroinferior instability in the young athlete

The etiology of shoulder pain in the overhead athlete is often difficult to determine. This study hypothesized that (1) instability can present in a purely painful form, without any apparent history of instability, but with anatomic lesions indicative of instability, termed unstable painful shoulder (UPS), and that (2) arthroscopic shoulder stabilization is effective.

Capsular imbrication for posttraumatic instability of the distal radioulnar joint

To analyze functional and subjective outcomes of patients with posttraumatic dorsal instability of the distal radioulnar joint (DRUJ) treated by a dorsal capsular imbrication.

The impact of CpG island methylator phenotype and microsatellite instability on tumour budding in colorectal cancer

In colorectal cancer, tumour budding, a process likened to epithelial mesenchymal transition, is an adverse prognostic factor which is rarely found in tumours with high-level microsatellite instability (MSI-H). Cases with MSI-H or high-level CpG island methylator phenotype (CIMP-H) have similar histomorphological features, yet seemingly opposite prognosis. We hypothesized that tumour budding is related to CIMP, thus partially explaining this prognostic difference.
