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.

Nonunions of the upper and lower extremity have been associated with pain and functional deficits. Recent studies have demonstrated that healing of these nonunions is associated with pain relief and both subjective and objective functional improvement. The purpose of this study was to determine which patient and surgical factors correlated with successful healing of a nonunion following surgical intervention. ⋯ Our data is similar to other studies assessing outcomes following other complex reconstructive procedures. It appears that more experienced (higher volume) reconstructive surgeons and the development of fewer postoperative complications is associated with greater success following repair of a long bone nonunion. Infection at any point during treatment is associated with failure to achieve successful union.

ReviewOutcomes of interlaminar and transforminal spinal injections.
Epidural spinal injections can be administered via a translaminar or transforaminal route, depending on the clinical scenario. When it is more desirable to target a specific nerve root, a transforaminal approach is typically used, and when the target is more diffuse, a translaminar method is chosen. Both are commonly used and can be utilized similarly in the lumbar or cervical spine. ⋯ In the lumbar spine, both translaminar epidural steroid injections (TLESI) and transforaminal epidural steroid injections (TFESI) have been shown to provide up to 6 months of pain relief, though long-term benefits are less reliable. In the cervical spine, translaminar injections may provide longer relief and have a lower complication rate than cervical transforaminal injections. Proper technique is essential to minimize the rate of these rare but occasionally severe complications.

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.
