Posttraumatic Atlantoaxial Rotatory Dislocation in a Healthy Adult Patient: A Case Report and Review of the Literature
Case Reports in Orthopedics
Atlantoaxial rotatory dislocation (AARD) is a rare complication in adults usually leading to pain, spinal cord injury, or death. Clinical and radiological diagnosis is difficult and often delayed. We report a rare case of posttraumatic AARD in a neurological intact 27-year-old male in which initial radiographic evaluation was negative. A computed tomography (CT) scan was promptly done because the patient showed a severe torticollis. Therefore, early diagnosis, immobilisation, and surgical fusion and arthrodesis were performed. After surgery, cervical pain and torticollis were resolved and the patient remained neurologically intact with a CT scan documentation of fusion at the 3-year followup.
Heterotopic Ossification in Vertebral Interlaminar/Interspinous Instrumentation: Report of a Case
Case Reports in Surgery
We present here a rare case of heterotopic ossification in interspinous/interlaminar Coflex device. The classical surgical indications for these implants are degenerative canal stenosis, discogenic low back pain, disk herniations, facet syndrome, and instability. However, fractures of spinous processes are a potential risk after interspinous/interlaminar devices' implantation. Recently, heterotopic ossification, a well-known complication of hip and knee arthroplasty, has been reported after cervical and lumbar prosthesis. We performed undercutting and implantation of the dynamic interspinous/interlaminar device to treat an adult male patient with L4-L5 stenosis. The patient underwent 45-day imaging and clinical followup, and we observed both a neurological and imaging improvement. A CT bone scan, performed 3 years after surgery for recurrence of neurogenic claudication, showed a new stenosis due to an abnormal ossification all over the device. To our knowledge, this is the first reported case of heterotopic ossification in an interspinous/interlaminar dynamic device. Accordingly, we aim to suggest it as a new complication of interspinous/interlaminar devices.
Spontaneous and idiopathic chronic spinal epidural hematoma: two case reports and review of the literature
Cavallo, Michele Alessandro
European Spine Journal
Spinal epidural hematoma (SEH) represents the most frequent entity of acute or chronic spinal bleeding. Based upon pathogenesis, SEH can be classified as idiopathic, spontaneous, and secondary. The idiopathic forms are considered not to be attributed to any specific risk factors. Spontaneous SEH, accounting for 0.3–0.9% of all spinal epidural space occupying lesions, instead is associated with risk factors (such as substantial soft trauma or coagulation abnormalities). The chronic form, as our literature review revealed, is the rarest and its most frequent location is the lumbar spine. The pathophysiology of spontaneous and idiopathic SEH is still under debate: There are only a few reports in literature of chronically evolving SEH with progressively increasing pain and neurological impairment. Magnetic resonance imaging may be inconclusive for differential diagnosis. Here, we present two cases of lumbar chronic SEH with slow, progressive, and persistent lumbar radicular impairment. The first patient reported a minor trauma with slight back contusion and thus was classified as spontaneous SEH. In the second case not even a minor trauma was involved, so we considered it to be idiopathic SEH. In both cases preoperative blood and coagulation tests were normal and we did not find any other or co-factors in the patients’ clinical histories. MR imaging showed uncertain spinal canal obstructing lesions at L3 and L4 level in both cases. Surgical treatment allowed a correct diagnosis and resulted in full clinical and neuroradiological recovery after 1 year follow-up. Our aim is to discuss pathogenesis, clinical and radiological features, differential diagnosis and treatment options, on the background of relevant literature review.
