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.

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.

Transarticular C1-2 screws are widely used in posterior cervical spine instrumentation. Injury to the vertebral artery during insertion of transarticular Cl-2 screw remains a serious complication. Use of a computer-assisted surgery system decreases this complication considerably. However, this system encounters problems in ensuring complete accuracy because of positional variations during preoperative and intraoperative imaging generation. Therefore, intraoperative fluoroscopy still is one of the commonly used methods to guide insertion of transarticular Cl-2 screw. Evaluation of a true lateral radiographic view of the C2 pedicle for screw trajectory during C1-2 transarticular screw insertion may help to minimize this potential complication. ⋯ True lateral radiographic views of the pedicles provide useful information for defining screw trajectory intraoperatively. Using this view along with AP and lateral view of cervical spine and preoperative three-dimensional CT scan may narrow the margin of error in this delicate area.

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.
