You will be provided with the titles and abstracts of a collection of medical RCT reports studying a clinical question -- for instance, the efficacy of an intervention on some medical outcome. Please write a few sentences synthesizing the findings of these reports, which could serve as a conclusion section for a systematic review article. Your response should not include any other text. The RCT reports are below.



Title 1:
Low-intensity pulsed ultrasound (LIPUS) in fresh clavicle fractures: a multi-centre double blind randomised controlled trial.
Abstract 1:
Several randomised trials have been published on the effect of low-intensity pulsed ultrasound (LIPUS) on fracture healing in both distal radius and tibia fractures. Most studies showed a positive effect on time to clinical and radiological healing. We hypothesised that LIPUS has a beneficial effect on the healing of fresh clavicle fractures as well and studied its effect in non-operatively treated shaft fractures.
                We conducted a randomised double blind, placebo-controlled multi-centre trial in 101 adult patients with a non-operatively treated fresh clavicle shaft fracture. Of these patients, 49 used a placebo transducer and 52 patients had an active transducer with ultrasound stimulation (Exogen 2000). Data were analysed on intention to treat basis. Baseline parameters of both groups were not significantly different.
                There were no differences in time to subjective clinical fracture healing, resumption of daily activities, sports or professional work, Visual Analogue pain Scores (VAS) and use of pain medication.
                Our findings did not confirm that LIPUS accelerates clinical healing time of fresh clavicle shaft fractures.
                Level 1 evidence that low-intensity pulsed ultrasound does not accelerate clinical fracture healing in non-operatively treated fresh midshaft clavicle fractures.


Title 2:
Treatment of clavicular fractures. Figure-of-eight bandage versus a simple sling.
Abstract 2:
Seventy-nine out-patients with midclavicular fractures were included in a prospective, randomized trial comparing treatment with a figure-of-eight bandage and a simple sling. Sixty-one patients completed the study and were reevaluated clinically and radiographically after 3 months. We found that treatment with a simple sling caused less discomfort and perhaps fewer complications than with the figure-of-eight bandage. The functional and cosmetic results of the two methods of treatment were identical and alignment of the healed fractures was unchanged from the initial displacement.


Title 3:
[Conservative treatment of clavicular fractures].
Abstract 3:
nan
There is insufficient evidence from randomised controlled trials to determine which methods of conservative treatment are the most appropriate for acute middle third clavicle fractures in adolescents and adults. Further research is warranted.
