BACKGROUND Few randomized controlled trials have compared operative with nonoperative treatment of clavicular fractures. METHODS Patients with displaced midshaft clavicular fractures were randomized either to nonoperative treatment with a sling or to operative treatment with a stainless steel 3.5-mm reconstruction plate. Outcome measures were the Constant(More)
BACKGROUND Conservative treatment of acromioclavicular (AC) joint dislocation is not always successful. A consequence of persistent AC joint dislocation may be chronic pain and discomfort in the shoulder region as well a sensation of constant AC joint instability and impaired shoulder function. Stabilization of the AC joint may reduce these sequels. (More)
BACKGROUND AND PURPOSE Traditionally, clavicle fractures have been treated nonoperatively. However, many recent studies have concentrated on the results of operative treatment. We assessed and compared the outcomes of operative and nonoperative treatment for acute clavicle fractures in adults. METHODS We performed a systematic search of the medical(More)
RATIONALE AND OBJECTIVES The variation of measured magnetic resonance T1 relaxation times of autopsied human muscle samples is confusing. Hence, the authors studied rats' muscles to evaluate the effect of fiber type, the relative area of nonmyofiber space, fat and water content, cell death, and the mechanism of death on proton T1. METHODS Rats were(More)
BACKGROUND AND PURPOSE Long-term outcome after surgery for grade-V acromioclavicular joint dislocation has not been reported. We performed a retrospective analysis of functional and radiographic outcome 15-22 years after surgery. PATIENTS AND METHODS We examined 50 patients who were treated at our hospital between April 1985 and December 1993. Various(More)
A multitrauma victim was transported to our trauma centre. Smoke inhalation injury was suspected based on trauma history and clinical examination. The first trauma computer tomography (CT) obtained 2.8 h after the injury revealed subtle ground-glass opacifications with mainly peribronchial distribution and patchy peribronchial consolidations centrally in(More)
The aim of this study was to investigate sacroiliitis in patients with seronegative oligoarthritis. Thirty consecutive patients with seronegative oligoarthritis and no other signs of spondylarthropathy were included. Sacroiliac (SI) joints were investigated by both radiography and magnetic resonance imaging. HLA B27 antigen was studied and family history(More)
Background and purpose - The best treatment for displaced clavicle fractures has been debated for decades. Operative treatment has become more common. However, several randomized trials comparing non-operative and operative treatment have not shown any compelling evidence in favor of surgery. We identified the preferred treatment of displaced midshaft(More)
