Spinal dysraphisms are defined as open and closed dysraphisms. A hemivertebra is a congenital condition seen in 61% of patients with congenital anomalies. The first report of the excision of a hemivertebra was by Royle in 1928. A sixteen-year-old girl was admitted to our clinic with a congenital stain on the waist and a normal neurological examination. No new cases have been reported in recent literature. Our case, which is also rare, is associated with a tethered cord only and no other congenital abnormalities.

Chordomas are known as rare primary malign tumours that have formed from primitive notochord remains. Sacral chordomas grow slowly but locally and aggressively. Chordomas are locally invasive and have low tendency to metastasis and have a poor prognosis in long-term follow-up. Metastasis may be seen in a rate of 5–40% of the chordomas. Metastasis of chordomas is common in liver, lung, lymph nodes, peritoneum, and brain. The treatment approaches, including surgery, have been discussed in the literature before. Susceptibility to radiotherapy and chemotherapy is controversial in these tumours. The success of surgical treatment affects survival directly. In this report, we will report a sacral chordoma case in which an intraperitoneal distant metastasis occurred and discuss the surgical approach.

Retropulsion of free bone fragments extend the time of surgery and causes complications. This study found that there is no need to retropulse the bone fragments in the spinal canal in patients with unstable burst fractures who underwent total laminectomy and posterior long segment stabilization.

Background This aim of this study was to assess the effect of idiopathic intracranial hypertension (IIH) in the development of intracranial hypertension by measuring patients’ cerebrospinal fluid (CSF), brain, and segment volumes. IIH is a disease of unknown cause characterized by chronic CSF pressure elevation and papillary edema. Under the Monro–Kellie doctrine, efforts have been made to explain the disease through an increase in the volumes of one or two of brain, blood or CSF in the intracranial cavity, although these have not been completely successful. Methods Twelve IIH patients diagnosed based on the modified Dandy criteria and 15 age- and sex-compatible healthy controls were included in the study. Cases’ 3D T1 sequence images were evaluated using the voxel-based volumetric analysis system (volBrain). Intracranial cavity extraction, macrostructures, and subcortical structure volumes were measured and compared. Results No statistically significant differences were observed between control cases’ and IIH patients’ CSF, cerebrum, cerebellum, brainstem, and subcortical structure volumes. Conclusion IIH arises from a chronic cause that does not impair the volumetric balance between structures inside the intracerebral cavity.

SummaryBackgroundCavernous malformations are characterized by enlarged vascular structures located in benign neural tissues within the cerebellum and spinal cord of the central nervous system. Cavernous hemangiomas (CHs) account for 5% to 12% of all spinal vascular malformations.Case ReportWe removed a hemorrhagic thoracic mass in a 40-year-old male patient who presented with progressive neurological deficits.ConclusionsWe found it appropriate to present this case due to its rarity.

Amaç: Koksidinalı hastalarda morfolojik ve patolojik anatominin özellikleri sınıflandırmayı amaçladık. Hastalar ve Yöntem: Nisan 2015-Nisan 2018 tarihleri arasında Alanya Alaaddin Keykubat Üniversitesi Eğitim Araştırma Hastanesine koksidina yakınması ile başvuran 16 yaş ve üzerindeki hastalar çalışmaya dahil edildi. Hastaların oturarak ve ayakta çekilen koksiks ve ön-arka pelvis grafileri retrospektif olarak incelendi. Bulgular: Koksiksin skolyozunun, hipermobilitesinin ve dislokasyonunun sakrokoksigeal açılanma ile ilişkili olmadığı görüldü. Hastaların oturarak ve ayakta çekilen koksiks grafi ölçümlerinde sakrokoksigeal ve interkoksigeal açıları arasında pozitif yönlü anlamlı bir ilişki bulundu. Ameliyat olmamış hastalarda sakrum ve koksiks uzunluğu arasında ve interkoksigeal açı ve koksiks uzunluğu arasında ilişki bulundu. Erkeklerde sakrokoksigeal eklem uzunluğu ile sakrokoksigeal açı ilişkili bulundu. Kadınlarda sakrokoksigeal eklemde füzyonun daha düşük olduğu tespit edildi. Sonuç: Koksidina yakınması ile gelen hastalar değerlendirilirken koksiksin tüm düzlemlerde hareket edebilen ve patoloji geliştirebilen bir omurga segmenti olduğu unutulmamalıdır. Bu hastaların yan ve AP pozisyonda oturarak ve ayakta çekilen dinamik direkt grafilerle değerlendirilmesi patolojinin bulunmasında etkili bir yöntemdir. Koksidinalı hastalarının sınıflandırılmasında her üç düzlemde patoloji içeren yeni sınıflandırma gereklidir. Sınıflandırmamızın bu eksikliği gidereceğini düşünmekteyiz.

ABSTRACTto some limitations in the long term. The biomechanics of the spine are also changing, because it creates non-physiological conditions by blocking movement (16).The idea of fusion in spinal surgery was raised for the first time at the beginning of the last century. When looking at the literature, it has been shown that the importance of spinal fusion was not exactly known before this period, and surgeons were content with fixation. Thereafter, the first fixation in the thoracolumbar spine by using wire was performed by Hadra █ INTRODUCTION T oday, posterior spinal stabilization and fusion interventions occupy an important place in neurosurgical practice. Spinal fusion and instrumentation are often applied to provide stability for an unstable spine, to avoid injury in the neurological structure, to reduce incorrect alignment and deformities, to increase the probability of fusion, and to reduce pain in the long term (8). Although this procedure has a very high success rate, the mechanism of the procedure can lead AIm: Many studies are available in the literature on posterior spinal instrumentation, though the use of a rod and a plate is still controversial in the literature. In this study, a finite element analysis of the strength and superiority of modular rigid plate and rod systems, which are used in the lower lumbar region, in comparison with each other was used. mATERIAl and mEThODS: A Ti6Al4V (Grade 5) titanium biocompatible alloy anterior plate was used for the lumbar spine fixation device, and a finite element analysis was conducted on the human lumbar spine model. In this study, an intact spine, a rigid system fixed with a rod, and modular plate systems were evaluated at flexion, extension, lateral bending, and axial rotation. RESUlTS:They did not show statistically significant superiority over one another in terms of limitations in movement during the range of motion exercises and rigidity. CONClUSION:The posterior rigid stabilization system and novel stabilization system do not have a significant superiority over one another. Equivalent results in the limitation of movement and rigidity allow for the use of these systems for short-segment posterior spinal instrumentation with the same indications.
