Conservative treatment for chronic coccydynia: a 36-month prospective observational study of 115 patients.

Purpose: To describe long-term outcomes of conservative treatment for chronic coccydynia.

Methods: We conducted a 36-month prospective observational study. Adults with chronic coccydynia (> 2 months) were included.

Osteopathic medicine for fibromyalgia: a sham-controlled randomized clinical trial.

Background: Patients with fibromyalgia (FM) frequently resort to osteopathic or chiropractic treatment, despite very weak supporting evidence. We aimed to assess the efficacy of osteopathic manipulation in FM in a properly controlled and powered randomized clinical trial.

Methods: Patients were randomized to osteopathic or sham treatment.

Classification of fractures of the coccyx from a series of 104 patients.

Purpose: To describe a classification of fractures of the coccyx, according to their mechanism.

Methods: A series of 104 consecutive patients with a fracture of the coccyx was studied. The mechanism, level, characteristics of the fracture line and complications were recorded.

Coccygectomy for coccygeal spicule: a study of 33 cases.

Purpose: To report the results of coccygectomy for coccygeal spicule.

Methods: We report the results of a retrospective series of 33 patients who underwent coccygectomy for coccygeal spicule. There were 31 women and 2 men.

Inflammatory pain pattern and pain with lumbar extension associated with Modic 1 changes on MRI: a prospective case-control study of 120 patients.

Purpose: To compare, in a case-control study, clinical characteristics of patients with low back pain (LBP) with and without Modic 1 signal changes on MRI.

Methods: Patients with chronic non-specific LBP and a recent (<6 months) MRI were prospectively screened and included in Modic 1 group or control group. Patients in control group were age- and gender-matched with patients with Modic 1 group.

Magnetic resonance imaging morphology and morphometry of the coccyx in coccydynia.

Study Design: Retrospective case-control study.

Objective: To determine if differences exists between the bony anatomy of the coccyx in patients with coccydynia and that in subjects with no known coccygeal pathology.

Summary Of Background Data: Numerous bony characteristics of the coccyx have been described in patients with coccydynia but their significance is uncertain.

CT morphology and morphometry of the normal adult coccyx.

Purpose: 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.

Methods: Retrospective analysis of 112 adult CT scans (mean age 63 ± 14.

Postpartum coccydynia: a case series study of 57 women.

Background: Although childbirth is a well-known cause of coccydynia, this condition has not been studied previously.

Aim: To explore the characteristics of postpartum coccydynia and identify risk factors.

Design: A case series study.

Magnetic resonance imaging findings in the painful adult coccyx.

Objective: Imaging of the painful coccyx currently relies on standard and dynamic radiography. There are no literature data on MRI of the coccyx. This examination could provide information on the cause of pain.

Lower back pain and neck pain: is it possible to identify the painful side by palpation only?

Objectives: Back pain is often attributed to increased tension in the back muscles, regardless of whether the tension is primary or related to a disc/facet pathology. We hypothesized that when either lower back pain or neck pain is unilateral, the muscle tension would be more pronounced on the painful side and could be detected by palpation alone (i.e.

Chronic coccydynia in adolescents. A series of 53 patients.

Background: Little is known about coccydynia in adolescents.

Aim: The aim of this study was to explore causes, clinical and imaging features and response to treatment of chronic coccydynia in adolescents.

Design: This was a cohort study.

Xiphodynia and prominence of the xyphoid process. Value of xiphosternal angle measurement: three case reports.

We describe three cases of xiphodynia in patients with prominence of the xyphoid process under the skin. The xiphosternal angle was 105°, 135°, and 120° in these three patients, respectively, compared to a mean of 172 ± 15° in 60 individuals without xiphodynia evaluated by computed tomography for another reason. The prominence of the xyphoid process caused discomfort and local irritation and was the source of the pain in all three patients.

Prevention of post-coccygectomy infection in a series of 136 coccygectomies.

Postoperative infection is a regular complication in coccygectomy. The authors propose the use of a topical skin adhesive on the postoperative wound as a contribution to the prevention of this complication. It was used on the first 56 patients in this study.

Four cases of coccygeal disk calcification after cortivazol injection.

Chronic coccydynia can be treated with a glucocorticoid injection into the pain-causing intercoccygeal disk. We report four cases of calcifications within intercoccygeal disks previously injected with cortivazol. In two patients, the calcifications probably caused additional pain.

Interexaminer agreement of clinical examination of the neck in manual medicine.

Objectives: To assess interexaminer agreement in a structured, manual, clinical examination of the neck. To correlate these data with the score in a functional questionnaire (a validated, French-language version of the neck pain and disability scale).

Patients: Fifty-nine ambulatory patients (26 males and 33 females, mean+/-SD age: 46.

Coccydynia related to calcium crystal deposition.

Study Design: Study of 4 cases of severe coccydynia revealing calcium deposits in the sacrococcygeal and intercoccygeal joints.

Objective: To highlight calcium crystal deposition as a cause of sudden-onset coccydynia.

Summary Of Background Data: Intervertebral disc calcification in the cervical, thoracic, or lumbar spine is well known, but calcifications in the sacrococcygeal or intercoccygeal joints with symptoms have never been reported.

[Is systematic radiography needed before spinal manipulation? Recommendations of the SOFMMOO].

Objectives: The French National Health Authority recommends systematic radiography before lumbar manipulation. However, current research shows radiography to have more disadvantages than advantages. For the cervical spine, in cases of complication following cervical manipulation, the lack of prior radiography is a fault, even if such x-ray results would have advised manipulation.

The treatment of chronic coccydynia with intrarectal manipulation: a randomized controlled study.

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%.

Towards a model of back pain. The 3 circles of pain.

A new model for back pain is introduced. Three major groups (or ''circles'') of pain are described for the use of clinicians. The 1(st) circle is comprised of patients with pain from genuine spinal (mainly discs or facets) origin.
