To investigate whether the behavior of disc arthroplasty in 2-level hybrid surgery (HS) was affected by adjacent fusion in vivo compared with cervical disc arthroplasty (CDA) alone. ⋯ Although the fusion in 2-level HS partially affected the behavior of adjacent disc arthroplasty compared with CDA alone, it did not cause severe complications and adverse clinical outcomes. However, large-scale and long follow-up trials are warranted.

Risk factors for cage retropulsion after lumbar interbody fusion: A systematic review and meta-analysis.
Although many risk factors for cage retropulsion (CR) after lumbar interbody fusion (LIF) have been described in the literature, they still remain controversial. The purpose of this study is to investigate the risk factors for CR after LIF. ⋯ According to current evidence, a pear-shaped disk and straight cage are significant risk factors for CR. However, preoperative diagnosis, gender, multilevel fusion, surgical segments, and unilateral pedicle screws fixation are not the risk factors associated with CR. A revision surgery is needed when neurologic symptoms happen after CR. The conclusion should be consulted cautiously due to the limited number of included studies. Therefore larger-scale studies are still needed to investigate the risk factors for CR.

Very long-term outcomes are rarely reported for patients with shunted pediatric hydrocephalus. This study aimed to determine the functional, social, and neurocognitive outcomes of such patients after transition to adulthood. ⋯ The overall long-term outcome of patients with shunted pediatric hydrocephalus is poor. These results highlight the importance of lifelong routine controls to avoid later complications. Further, repeated neuropsychological examinations might be important to understand the patient's special needs to optimize professional support.

Posterior fossa tumors are rare in adults and pose a challenge to treat due to the bony contour of the posterior fossa, complex anatomical structures including deep venous sinuses, and the proximity of the fourth ventricle and brain stem. We describe our experience with laser interstitial thermal therapy (LITT) for the management of brain metastases and radiation necrosis of the posterior fossa. ⋯ Lesions of the posterior fossa are challenging to treat given their proximity to the dura and venous sinuses. Our findings demonstrate that LITT ablation may be a safe and feasible option for metastases and radiation necrosis of the posterior fossa. Larger studies are needed to confirm the efficacy of this approach.

Hydrocephalus is the most common complication of extraparenchymal neurocysticercosis, combining obstructive and inflammatory mechanisms that impair cerebrospinal fluid circulation. ⋯ Our neurocysticercosis-induced hydrocephalus model allows for the long-term maintenance of hydrocephalic animals, involving mild clinical performance impairments, including body weight and behavioral changes.
