Review Meta Analysis
Timing of extremity fracture fixation in patients with traumatic brain injury: A meta-analysis of prognosis.
Traumatic brain injury (TBI) is a common public health problem. The optimal timing of fracture fixation in patients with TBI has remained controversial. We conducted a meta-analysis to quantitatively discuss the effects of fixation timing on the prognosis of patients with extremity fracture and concomitant TBI. ⋯ Late fracture fixation conducted >14 days after injury was associated with nonunion or malunion. Fixation performed within 24 hours did not influence mortality or adverse neurologic events.

Review Meta Analysis Comparative Study
Minimally Invasive versus Open Transforaminal Lumbar Interbody Fusion for Single-Level Degenerative Disease: Systematic Review and Meta-Analysis of Randomized Controlled Trials.
We compared the safety and effectiveness of minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) to open TLIF (O-TLIF) for lumbar degenerative disease. ⋯ Relative to O-TLIF, MI-TLIF was associated with less blood loss, a shorter hospital stay, and slightly less disability, at the expense of longer fluoroscopy times.

Pilocytic astrocytoma (PA) is rare in adults comprising 5.1% of the primary central nervous system tumors. The aim is to describe the first Brazilian series of adult patients with PA and compare its features with the available literature. ⋯ This is the first Brazilian series regarding adults with PA, and our patients had a favorable outcome as reported in recent literature reviews. The tumor's prevalence reduces within older patients and supratentorial lesions are more frequent, especially on the temporal lobe. There was no significant relationship between location and progression, although according to the literature the extent of resection remains the most important prognostic factor.

Delayed postoperative hemorrhage (DPOH) was a severe postoperative complication after intracranial epidermoid cyst (EC) surgery. This study was designed to investigate possible clinical data and image features related to DPOH in patients with EC. ⋯ Mixed signal intensity on preoperative T1 MRI might be associated with DPOH in patients with EC. The surgeon should pay more attention to this rarely atypical imaging before surgery. Further observations are necessary to illustrate the relationship between mixed signal intensity and DPOH in EC and to guide reasonable therapy.

This study was carried out to analyze the surgical effect of cervical spine sagittal alignment for patients with Hirayama disease (HD). ⋯ Patients with HD have sagittal imbalance of the cervical spine compared with age-matched healthy adolescent subjects, and surgical treatment could correct the sagittal imbalance.
