Low back pain, the stiffness of the sacroiliac joint: a new method using ultrasound.
Abnormal biomechanical properties of the sacroiliac joints are believed to be related to low back and pelvic pain. Presently, physiotherapists judge the condition of the sacroiliac joints by function and provocation tests, and palpation. No objective measuring device is available. ⋯ Vibration amplitudes from 0.25 microm to 3 microm could be measured. The US technique was able to detect bone vibration in vivo. In conclusion, the principle based on US waves can be used to develop a new measurement tool, instrumental in studying the relation between the biomechanical properties of the sacroiliac joints and low back pain.

Initial treatment of pelvic ring fractures with involvement of the iliosacral complex is directed at bleeding control and fixation of the pelvic ring. However, long-term outcome is determined by persisting neurological deficits, malunion of the posterior pelvic ring with low back pain, and urological lesions. Between 1991 and 2000, 173 patients with sacral fractures were treated at our institution. ⋯ Chronic low back pain was rarely observed (n=8, 7%) and only in type C injuries. The low incidence of chronic low back pain justifies conservative treatment of minimally (<1 cm) displaced sacral fractures. Long-term outcome is largely determined by neurological deficits, which persist in 30% of all patients with sacral fractures.

Randomized Controlled Trial Clinical Trial
Treatment of pregnancy-related pelvic girdle and/or low back pain after delivery design of a randomized clinical trial within a comprehensive prognostic cohort study [ISRCTN08477490].
Pregnancy-related pelvic girdle and/or low back pain is a controversial syndrome because insight in etiology and prognosis is lacking. The controversy relates to factors eliciting pain and some prognostic factors such as the interpretation of pain at the symphysis. Recent research about treatment strategies also reflects those various opinions, in fact suggesting there is professional uncertainty about the optimal approach. Currently, physiotherapists often prescribe a pain-contingent treatment regime of relative rest and avoiding several day-to-day activities. Additionally, treatment more often includes an exercise program to guide rectification of the muscle imbalance and alignment of the pelvic girdle. Effectiveness of those interventions is not proven and the majority of the studies are methodologically flawed. Investigators draw particular attention to biomedical factors but there is growing evidence that important prognostic issues such as biopsychosocial factors appear to be even more important as point of action in a treatment program. ⋯ This section briefly discusses the actions taken to minimize bias in the design, the proper time-window for the experimental intervention and the contrast between the experimental intervention and usual care.
