It has been found that the pain patterns in pain drawings are related to the presence of herniated disc identified by myelography. The purpose of this study was to determine whether the pattern of pain in the drawings or the type of pain indicated (aching, burning, numbness, pins and needles, stabbing) was related to the presence of symptomatic disc pathology identified by CT/discography. In a subgroup of patients who underwent myelography, the relationship of the drawings to myelographic findings was also investigated. ⋯ Patients with discogenic pain used more symbols indicating burning pain and aching pain than did non-discogenic pain patients. Our results confirmed those reported earlier by Uden, who found a relationship between the pattern of pain in the drawings and myelographic findings. Pain drawings may be helpful in the diagnosis of symptomatic disc pathology.

Reconstruction of anterior iliac crest bone graft donor sites: presentation of a surgical technique.
This study is a prospective evaluation of the reconstruction of anterior iliac crest bone graft donor sites using a technique developed by the authors. We present the technique and the initial results obtained with its use in 15 patients followed up for a period ranging from 6 to 16 months. ⋯ Clinical evaluation of the patients found a good cosmetic appearance of the reconstruction site, and the rib segments used showed good radiologic integration. Partial resorption of the segments was observed in two patients, with no effects on the cosmetic result.

This study retrospectively reviews 20 sequential patients with thoracolumbar burst fractures without neurologic deficit. All patients were treated by indirect reduction, bisegmental posterior transpedicular instrumentation and monosegmental fusion. Clinical and radiological outcome was analyzed after an average follow-up of 6.4 years. ⋯ Therefore, posterolateral fusion alone does not prevent disc space collapse. Nevertheless, clinical long-term results are favorable. However, if disc space collapse has to prevented, an interbody disc clearance and fusion is recommended.

This cadaver study evaluated the value of MR images for detection of acute intervertebral disc damage associated with fractures of the thoracolumbar spine. Damage to the intervertebral disc may be a major contributor to chronic instability in non-operative treatment or failure of fixation and recurrence of deformity in posterior fixation methods. MR imaging can help us to understand the injury patterns and their prognostic significance. ⋯ These were all detected on the corresponding MR images. The study showed that MRI is able to detect acute, macroscopic injury to the intervertebral disc. It is therefore justified to use MR for the study of acute disc damage associated with thoracolumbar fractures.

Various conditions such as fracture, dislocation, tumor, or infection adversely affect the vertebral body and lead to instability. Restoration of a stable anterior column is essential for normal spinal biomechanics. Various biological and mechanical spacers have been used to reconstruct the anterior column after corpectomy. ⋯ For patients presenting with neurological symptoms (n = 4), the recovery was complete in three and partial in one. No patient was made neurologically worse, and there were no vascular injuries intra- or postoperatively. The study suggests that TSM-bone graft composite offers excellent biomechanical stability in the immediate postoperative period, permitting progressive maturation of the fusion mass.
