Uncovertebral hypertrophy is a significant risk factor for the occurrence of heterotopic ossification after cervical disc replacement: survivorship analysis of Bryan disc for single-level cervical arthroplasty.
The purpose of this study is to investigate the incidence of heterotopic ossification (HO) in the Bryan cervical arthroplasty group and to identify associations between preoperative factors and the development of HO. ⋯ These findings suggest that the condition of the uncovertebral joint must be evaluated in preoperative planning for Bryan cervical arthroplasty.

Randomized Controlled TrialDynamics of brain tissue changes induced by traumatic brain injury assessed with the Marshall, Morris-Marshall, and the Rotterdam classifications and its impact on outcome in a prostacyclin placebo-controlled study.
The present study evaluates the types and dynamics of intracranial pathological changes in patients with severe traumatic brain injury (sTBI) who participated in a prospective, randomized, double-blinded study of add-on treatment with prostacyclin. Further, the changes of brain CT scan and their correlation to Glasgow Coma Scale score (GCS), maximal intracranial pressure (ICP(max)), minimal cerebral perfusion pressure (CPP(min)), and Glasgow Outcome Score (GOS) at 3, 6, and 12 months were studied. ⋯ The Rotterdam classification seems to be appropriate for describing the evolution of the injuries on the CT scans and contributes in predicting of outcome in patients treated with an ICP-targeted therapy. The Morris-Marshall classification can also be used for prognostication of outcome but it describes only the impact of traumatic subarachnoid hemorrhage (tSAH).

Comparative StudyCerebral arteriovenous malformations and seizures: differential impact on the time to seizure-free state according to the treatment modalities.
To determine the prognostic factors for the incidence and the outcome of seizure in patients with cerebral arteriovenous malformation (AVM) and to identify the time to seizure-free state according to the treatment modalities. ⋯ A multidisciplinary team approach for cerebral AVMs achieved satisfactory seizure control results. Microsurgery led to the highest percentage of seizure-free outcomes and had the lowest annual bleeding rate, whereas radiosurgery had a higher bleeding rate. Median time to seizure-free status in surgically treated patients was shorter than in patients who underwent radiosurgical or endovascular treatment.

Discography is used as an aid in the diagnosis of back pain related to intervertebral disc pathology. It involves attempting to elicit the patient's pain symptoms by injecting contrast into the suspected pathological disc. The overall complication rate of discography is low, with discitis being the most common complication and acute disc herniation post lumbar discography being reported in a small number of cases. We describe the case of a patient who developed cauda equina compression post lumbar discography.

Factors predicting recurrence of chronic subdural haematoma: the influence of intraoperative irrigation and low-molecular-weight heparin thromboprophylaxis.
Burr-hole drainage has become the accepted treatment of choice for chronic subdural haematoma (cSDH), although still burdened with a major recurrence rate. The current analysis was initiated to determine management-related risk factors for recurrence, i.e. postoperative low-molecular-weight heparin thromboprophylaxis, and the importance of rinsing the subdural space. ⋯ The investigation provides evidence that copious intraoperative irrigation and avoidance of postoperative low-molecular-weight heparin thromboprophylaxis may reduce the recurrence rate of cSDH.
