Multicenter StudyHospital for joint diseases participates in international spine registry Spine Tango after successful pilot study.
Spine Tango is currently the only international spine registry in existence. It was developed under the auspices of Eurospine, the Spine Society of Europe, and is hosted at the University of Bern, Switzerland. ⋯ Workflow integration and dedicated research staff are key factors for such an endeavor. Participation enables benchmarking against national and international peers and outcome research and quality assurance of surgical and non-surgical treatments.

In a follow-up study, patients are monitored over time. Longitudinal and time-to-event studies are the two most important types of a follow-up study. In this paper, the focus is on longitudinal studies with a continuous response where patients are examined at several time points. ⋯ We will illustrate that there are interpretational and computational issues with the "classical" approaches. Further, we expand here on more appropriate statistical techniques to analyze longitudinal studies. To this end, we focus on randomized controlled trials (RCTs) and illustrate the approaches on data from a fictive randomized controlled trial in rheumatology.

Case ReportsExtensor indicis proprius and extensor digitorum communis rupture after volar locked plating of the distal radius--a case report.
Distal radius fractures are among the most commonly encountered fractures in the extremities. Volar plating of distal radius fracture has gained popularity in recent years with the introduction of the locked plating system. Complications of volar plating include extensor and flexor tendon rupture. Here we present a case report of an extensor indicis proprius and extensor digitorum communis to index finger tendon rupture after open reduction and internal fixation of distal radius fracture with locked plate.

Comparative StudyThe outcomes of Cormet hip resurfacing compared to standard primary total hip arthroplasty.
Metal-on-metal hip resurfacing has provided an alternative to standard total hip arthroplasty in younger, more active patients. However, detractors argue that many of the benefits of resurfacing can be obtained with the use of larger femoral heads. The purported advantages of the resurfacing procedure include preservation of femoral bone stock, increased range of motion, decreased dislocation rate, excellent performance in high-activity patients, and a potentially easier revision than total hip arthroplasty. The purpose of this study was to examine the outcomes of patients who had hip resurfacing and to compare them to all total hip arthroplasty procedures performed during the same time period. ⋯ Excellent results continue to be demonstrated with hip resurfacing systems, with equal, early survivorship when compared to total hip arthroplasty. For patients who meet the appropriate selection criteria and in the hands of an experienced, high-volume arthroplasty surgeon hip resurfacing provides excellent early results.

Case ReportsIsolated Hoffa fracture of the medial femoral condyle in a skeletally immature patient.
Intraarticular coronal fracture of the femoral condyle is rare, and an isolated medial Hoffa fracture in a child is extremely rare. To our knowledge, such a case has not yet been reported in the literature. Early diagnosis and prompt treatment are essential for a good long-term outcome. ⋯ At the 36-month follow-up, the fracture was united, and the patient had full extension and approximately 130° flexion of knee. There was no varus or valgus instability or limb length discrepancy. This case highlights the importance of early diagnosis and prompt treatment in the form of epiphyseal fixation for the management of these fractures in skeletally immature individuals.
