- Fig 1.
Sagittal T1 MR imaging demonstrating fracture types. Stars indicate treated fractures. A, Type 1 fracture, considered probably osteoporotic in nature. Areas of preserved, high T1 signal intensity within the fractured vertebral body, without focal intravertebral lesion and no evidence for pedicle involvement or epidural or paraspinal disease (not shown). B, Type 2 fracture, indeterminate for underlying lesions. Diffusely low signal intensity marrow throughout the spine. No focal lesion or epidural or paraspinal lesion within the treated vertebral body. C, Type 3 fracture, with clear evidence for myelomatous lesion within the treated vertebral body.
- Fig 2.
Treated and affected levels. Vertebral level frequency histograms of 114 treated vertebral levels (A) and 216 affected vertebral levels (B) in the 67 patients composing the myeloma study population. Diffuse myeloma involvement (>10 vertebral bodies) was not included in this histogram.
- Fig 3.
Time to treatment. Time to treatment of myeloma study participants is shown as a function of a frequency histogram with each bin representing a 4-month period.
- Fig 4.
Objective clinical outcome scores over time. Mean (± SD) RDQ and analog pain scale (pain with rest and activity) scores are shown preoperatively (baseline), postoperatively, and 1 week, 1 month, 6 months, and 1 year after vertebroplasty.
Tables
Subjective outcome scores collected throughout follow-up
Variable Time Postoperation 1 Week 1 Month 6 Months 1 Year Rest pain +1.25 +1.33 +1.29 +1.53 +1.49 Active pain +1.10 +1.12 +1.00 +1.33 +1.12 Mobility +0.76 +0.67 +0.83 +1.00 Narcotic use +0.81 +0.84 +0.93 +0.94 Note:—Subjective outcome scores as compared with preoperative status: +2 indicates total improvement; +1, some improvement; 0, no change; −1, worse. Scores were calculated as described in the Methods section. Mobility and narcotic use were not determined until 1 week had passed after treatment.
