STUDY DESIGN This prospective study consisted of the evaluation of a double sacroiliac block in patients with low back pain. OBJECTIVES To determine the prevalence of sacroiliac pain in a selected population of patients suffering from low back pain, and to assess certain pain provocation tests. SUMMARY OF BACKGROUND DATA Previous studies have implicated(More)
Coccygectomy is a controversial operation. Some authors have reported good results, but others advise against the procedure. The criteria for selection are ill-defined. We describe a study to validate an objective criterion for patient selection, namely radiological instability of the coccyx as judged by intermittent subluxation or hypermobility seen on(More)
Low back pain persisting or appearing after a technically successful lumbar fusion challenges clinicians. In this context, the sacroiliac joint could be a possible source of pain, but the frequency of its responsibility is not really known. We used sacroiliac anesthetic blocks, the gold standard for diagnosis, to determine this frequency. Our second goal(More)
STUDY DESIGN Ninety-one patients with common coccygodynia and 47 control subjects prospectively underwent dynamic radiographic imagery. OBJECTIVES To standardize the radiologic protocol to better define normal and abnormal mobility of the coccyx, and to study clinical parameters useful in classifying and differentiating the lesions. SUMMARY OF(More)
STUDY DESIGN The authors hypothesized that the source of coccygodynia was a lesion of the coccygeal disc. OBJECTIVES This study analyzed the motion of the painful coccyx in the sitting position as compared with the lateral decubitus in a patient and a control group and reported the first results of coccygeal discography (dynamic study). SUMMARY OF(More)
STUDY DESIGN A total of 208 consecutive coccydynia patients were examined with the same clinical and radiologic protocol. OBJECTIVES To study radiographic coccygeal lesions in the sitting position, to elucidate the influence of body mass index on the different lesions, and to establish the effect of coccygeal trauma. SUMMARY OF BACKGROUND DATA A(More)
STUDY DESIGN In this study, the authors analyzed the results of the release of the medial superior cluneal nerve in a prospective series of 19 patients with suspected entrapment. OBJECTIVES To ascertain, in selected patients with low back pain, medial superior cluneal nerve entrapment compromise at the posterior iliac crest crossing site, and to evaluate(More)
Recent research has shown significant adverse effects of chronic low back pain on sexual activity in 46% of patients. To establish whether and how chronic low back pain adversely affects sexual activity, a questionnaire-based study was conducted on a patient group (low back pain) and a comparison group (neck pain). Patients were administered a visual analog(More)
STUDY DESIGN Randomized open study. OBJECTIVE To evaluate the efficacy of intrarectal manual treatment of chronic coccydynia; and to determine the factors predictive of a good outcome. SUMMARY OF BACKGROUND DATA In 2 open uncontrolled studies, the success rate of intrarectal manipulation of the coccyx was around 25%. METHODS Patients were randomized(More)
Lack of data on the in vivo morphology and morphometry of the normal adult coccyx hampers understanding of radiological abnormalities in idiopathic coccydynia. The aim of this study was to investigate normal adult sacrococcygeal morphometry. Retrospective analysis of 112 adult CT scans (mean age 63 ± 14.6 years, 50 males) evaluated the following: number of(More)
