Randomized Controlled Trial Multicenter Study Clinical Trial
Treating acute low back pain with continuous low-level heat wrap therapy and/or exercise: a randomized controlled trial.
Restorative exercise and palliative modalities are frequently used together for the treatment of acute low back pain. However, little is known about the effects of combining these treatments. ⋯ Combining continuous low-level heat wrap therapy with directional preference-based exercise during the treatment of acute low back pain significantly improves functional outcomes compared with either intervention alone or control. Either intervention alone tends to be more effective than control.

In a small prospective study assessing 10 symptomatic and 10 asymptomatic subjects, Schellhas et al. compared cervical discography to magnetic resonance imaging. Within that study he reported on the distribution of pain for the C3-C4 to C6-C7 levels. Four years later, Grubb and Ellis reported retrospective data from his 12-year experience using cervical discography from C2-C3 to C7-T1 in 173 patients. To date, no large prospective study defining pain referral patterns for each cervical disc has been performed. ⋯ In conclusion, these results confirm the observations of prior investigators that cervical internal disc disruption can elicit axial and peripheral symptoms. The particular patterns of pain generation allow the discographer to preprocedurally anticipate disc levels to assess. With these data, the number of disc punctures that are required can be limited rather than routinely assessing all cervical discs.

The "centralization phenomenon" (CP) is the progressive retreat of referred pain towards the spinal midline in response to repeated movement testing (a McKenzie evaluation). A previous study suggested that it may have utility in the clinical diagnosis of discogenic pain and may assist patient selection for discography and specific treatments for disc pain. ⋯ Centralization is highly specific to positive discography but specificity is reduced in the presence of severe disability or psychosocial distress.

Case Reports
Spinal epidural hematoma after a pathologic compression fracture: an unusual presentation of multiple myeloma.
Spinal epidural hematoma can result from traumatic and atraumatic etiologies. Atraumatic spinal epidural hematomas have been reported as an initial presentation of multiple myeloma. There are no other reports previously describing spinal epidural hematoma after a pathologic spinal fracture. ⋯ This is the first reported case of spinal epidural hematoma after a pathologic spinal fracture. Also, this case represents an unusual initial presentation of multiple myeloma in a young patient.

Acute onset of radicular symptoms has been reported following hemorrhage into lumbar synovial cysts after trauma or in cases of spinal instability. No previous cases have been linked to anticoagulation therapy. ⋯ This is the first reported case of symptomatic hemorrhagic lumbar facet cyst associated with anticoagulation therapy.
