To determine whether vertical laminar fracture (VLF) can distinguish between AO type A3 and A4 fractures. ⋯ We found VLF to be highly specific, sensitive, and reliable in detecting A4 fractures. A higher proportion of A4 fractures with VLF had radiographic parameters and neurological deficit than A4 fractures with no VLF. VLF could be used as a severity modifier to further discriminate A3 and A4 fractures regarding severity and potentially guide treatment decision making.

The clinical outcomes of balloon kyphoplasty (BKP) for split-type osteoporotic vertebral fractures (OVF) are poor. These may be owing to the vertebral body bifurcating anteriorly and posteriorly when a load is applied and the filled cement being unstable. We report the usefulness of BKP combined with pediculoplasty using cannulated screws (vertebra-pediculoplasty) for OVF with a risk of cement dislodgement. ⋯ Vertebra-pediculoplasty could be an effective method for managing OVF with a high risk of cement dislodgement, which has been difficult to treat using conventional BKP.

Review Case Reports
Misdiagnosis and delay of diagnosis in hemorrhagic meningioma: a case series and review of the literature.
To evaluate the clinicoradiologic characteristics of hemorrhagic meningiomas (HMs) that are missed or misdiagnosed on radiologic imaging studies. ⋯ Our study showed that in patients with HM with inadequate imaging evaluation, a small tumor associated with massive hematoma and atypical imaging features was more likely to be misdiagnosed.

Review Meta Analysis Comparative Study
Open-door versus french-door laminoplasty for patients with multisegmental cervical spondylotic myelopathy: a systematic review and meta-analysis.
This study aimed to evaluate the superiority of open-door versus French-door posterior cervical laminoplasty in the treatment of multisegmental cervical spondylotic myelopathy by comparing the intraoperative parameters and clinical and radiologic outcomes of these 2 procedures. PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, the Wanfang database, the Weipu database, and China Biology Medicine disk were searched. Articles were retrieved from database establishment through May 22, 2020. ⋯ This analysis suggests that both methods can achieve good postoperative outcomes. However, less intraoperative bleeding and a lower incidence of postoperative axial symptoms were found in the French-door group. This requires further validation and investigation in larger sample-size and well-designed randomized controlled studies.

Review Meta Analysis Comparative Study
Comparison of interventions for cervical ossification of posterior longitudinal ligament: a systematic review and network meta-analysis.
To summarize the literature and systematically evaluate outcomes for ossification of posterior longitudinal ligament interventions including anterior cervical corpectomy and fusion (ACCF), anterior controllable antedisplacement and fusion (ACAF), laminoplasty (LP), and laminectomy with fusion (LF). ⋯ Japanese Orthopaedic Association score outcomes indicated that ACCF was superior to LP and LF. ACAF had the largest cervical lordosis among all procedures. ACCF showed a higher incidence of overall complications compared with ACAF and LP.
