Imaging in early posttraumatic complex regional pain syndrome: a comparison of diagnostic methods.

Objectives: The complex regional pain syndrome type I (CRPS I) still is difficult to diagnose in posttraumatic patients. As CRPS I is a clinical diagnosis the characteristic symptoms have to be differentiated from normal posttraumatic states. Several diagnostic procedures are applied to facilitate an early diagnosis, although their value for diagnosing posttraumatic CRPS I is unclear.

Surgical and endovascular treatment of symptomatic aberrant right subclavian artery (arteria lusoria).

Right aberrant subclavian artery, also called arteria lusoria, is one of the most common intrathoracic arterial anomalies. Although mostly asymptomatic, the retroesophageal and retrotracheal course of the lusorian artery might result in unspecific thoracic pain, dysphagia, dyspnea, arterioesophageal or arteriotracheal fistulae with hematemesis or hemoptysis, and aneurysmal formation with relevant risk of rupture. The purpose was to present our experience with six patients with a symptomatic aberrant right subclavian artery, two patients with dysphagia or dyspnea caused by a nonaneurysmal lusorian artery, and four patients with arteria lusoria aneurysms.

MR imaging of ulnocarpal impaction after fracture of the distal radius.

Objective: The purpose of our study was to evaluate the incidence of ulnocarpal impaction after distal radius fracture using MR imaging and to correlate imaging findings with those of radiography and clinical findings.

Conclusion: Ulnocarpal impaction is a common finding after distal radius fracture. MR imaging can detect characteristic bone marrow changes of the lunate early after the trauma.
