Review Case Reports
Controversies in the treatment of cervical spine dislocations.
Cervical spine dislocations represent an area of great controversy among spine surgeons. ⋯ Guidelines for the management of cervical spine dislocations are presented based on evidence-based medicine.

A recent study involving interbody fusion patients found that preoperative work status was significantly related to clinical outcome. In another study comparing the best and worst outcomes of total disc replacement, among a battery of variables analyzed, the only one that differentiated the best and worst outcome groups was the length of time off work before total disc replacement. ⋯ The results of this study found that patients off work for a longer duration before surgery improved significantly postoperatively, but had less favorable clinical outcomes than patients off work for a lesser duration. This study suggests a window of approximately 13 weeks off work before surgery after which clinical improvement is reduced. Implications of this finding may be that once a patient becomes unable to work for an extended period, more rigorous psychological screening may be in order as well as perhaps engaging in more rigorous rehabilitation after surgery. Further investigation is needed to determine if the 13 weeks identified in this study is applicable to other populations.

Primary tumors of the sacrum are extremely rare lesions. Their management is governed by an interplay of complex factors. Appropriate decision making is crucial to obtain the best possible outcome in terms of maximizing disease control while attempting to minimize neurological dysfunction. ⋯ Wide resection with adequate margins gives the best chance of local control and should be the surgery of choice for all malignant primary sacral tumors and in benign lesions involving lower segments when preservation of both S3 roots is possible. Intralesional curettage has a higher risk of local recurrence without providing the certainty of retaining neurological function. To retain bladder and bowel control and minimize neurological dysfunction, it may be worthwhile managing benign sacral tumors that extend above S3 with serial embolization. The administration of parenteral bisphosphonates may prove beneficial in cases of giant cell tumor managed with serial embolization.

Ten percent of patients with low back pain (LBP) are not able to resume work within 3 months of sick leave, accounting for 90% of all medical and indemnity costs. ⋯ A questionnaire comprising a limited set of items allows a practical screening of LBP patients unlikely to resume work.

The use of nonsteroidal anti-inflammatory drugs (NSAIDs) had been implicated as a risk factor for nonunion in spinal fusion. Even with a number of animal and human studies suggesting NSAIDs either delay or inhibit spinal fusion rates, these drugs continue to be used because of demonstrated benefits. Diclofenac sodium is no exception. It is very popular as a first-line treatment for acute pain, even perioperatively for spine fusion patients. Review of published literature reveals no studies done on the effect of diclofenac sodium on spine fusion rates. ⋯ Diclofenac sodium showed a dose-dependent inhibitory effect toward spine fusion especially when used during the immediate postoperative period. No significant correlation was seen between age, sex, L5-S1 versus other levels fused and smoking history when compared with spine nonunion. Two-level lumbar fusions also showed a significant negative correlation to spine fusion compared with single-level fusions.
