Posttraumatic Atlantoaxial Rotatory Dislocation in a Healthy Adult Patient: A Case Report and Review of the Literature

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

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

Validation of the Italian version of a new coma scale: the FOUR score

The Glasgow Coma Scale (GCS) is the most widely accepted tool for the evaluation of consciousness, despite several reported shortcomings. A new coma scale, named Full Outline of UnResponsiveness (FOUR) score, is now available. The aim of the present study is to provide and validate the Italian version of the FOUR score. The Italian version of the FOUR score was developed according to a standardized protocol, and thereafter validated in a series of patients with acute neurological illness. For each patient, the FOUR and the GCS scores were recorded by two physicians randomly selected. The inter-rater agreement for the FOUR and the GCS scores was evaluated using the weighted kappa (kappa(w)). The receiving operating characteristic curve was also calculated to determine the ability of the scales to predict outcome. Eighty-seven consecutive patients with an acute brain injury were enrolled. The inter-rater agreement was excellent both for the FOUR (kappa(w) = 0.953; P < 0.0001) and the GCS (kappa(w) = 0.943; P < 0.01). The area under the curve for mortality was 0.935 for the FOUR and 0.953 for the GCS. The FOUR score provides greater neurological details than the GCS. Our data indicate that the Italian version of the FOUR score is a valid predictor of outcome, yielding reproducible findings across raters independent of their expertise
