Sacroiliac Joint Dysfunction in Patients With Low Back Pain.

Although difficult to distinguish from similarly presenting syndromes, a detailed history, appropriate physical maneuvers, imaging, and adequate response to intra-articular anesthetic can help health care providers treat this painful condition.

Large distal anterior cerebral artery aneurysm treated with resection and interposition graft: case report.

OBJECTIVE: Distal anterior cerebral artery (DACA) aneurysms are rare, representing only 2% to 6.7% of all intracranial aneurysms. Most of them are small. Large and giant aneurysms are even rarer in this location. Only 26 giant pericallosal (PC) aneurysms have been reported thus far. Various surgical techniques have been used to treat these aneurysms, including direct aneurysm neck clipping, aneurysm trapping, proximal occlusion of the anterior cerebral artery, or a combination of clipping with coiling or a bypass procedure. The report presents an unusual case of a complex DACA aneurysm managed by resection and interposition arterial graft. CLINICAL PRESENTATION: A 69-year-old woman presented with acute onset of a severe headache. A digital subtraction angiogram showed a partially thrombosed, complex broad-necked A2-A3 junction aneurysm involving the origin of PC and callosomarginal vessels with a probability of a dissection of the DACA. The left PC artery was significantly narrowed. Because of the complex neck and involvement of the origin of PC and callosomarginal arteries, endovascular treatment was not possible, and microsurgical treatment was planned. TECHNIQUE: A large, partially thrombosed, and fusiform anterior cerebral artery A2-A3 aneurysm, with evidence of previous bleeding, was found and treated with resection and a short interposition graft using a segment of the superficial temporal artery. CONCLUSION: Surgical treatment of a large DACA aneurysm may be difficult due to a complex neck and the involvement of the branch vessels. Resection and interposition grafting and A3-A3 or A4-A4 anastomoses are treatment options for such patients.

U-shaped sacral fracture and lumbosacral dislocation as a result of a shotgun injury: case report.

OBJECTIVE: Gunshot wounds to the spine and/or sacrum rarely cause spinal instability. Our goal is to report the first case of a U-shaped sacral fracture and lumbosacral dislocation caused by a gunshot injury to the spine. CLINICAL PRESENTATION: A 37-year-old man sustained a close-range shotgun wound to the abdomen. The blast partially destroyed the L4 and L5 vertebral bodies and fractured the S1 and S2 segments of the spine, resulting in severe neurological deficits with lumbosacral and spinopelvic instability. INTERVENTION: Debridement of devitalized tissues, proper antibiotic coverage, decompression of the cauda equina, and lumbopelvic fixation. CONCLUSION: Close-range shotgun injuries result in massive destruction of tissues. As opposed to civilian injuries, a different approach must be taken to prevent infectious complications. A bilateral lumbopelvic fixation using long iliac screws effectively restored lumbosacral pelvic stability.

Sterile recurrent spinal epidural abscess in a patient with Crohn's disease: a case report.

BACKGROUND: The frequency of SEA is increasing. There are several well-established predisposing factors. CASE DESCRIPTION: Our case presents certain unusual features that include an association with CD, persistent sterile cultures, and multiple recurrences of lesions at adjacent levels. CONCLUSIONS: A review of the literature showed only 13 case reports of SEA in patients with CD with an additional patient mentioned in one series. Recurrence of SEA at the same location was reported only twice. The diagnostic workup and treatment modalities pertinent to this case are discussed.
