We sought to identify the morphological features of the relationship between the manubrium and vertebrae of the cervicothoracic junction for use in guidelines for the selection of the appropriate surgical approach. ⋯ Our results have provided insight into the anatomy of the manubrium and vertebrae of the cervicothoracic junction. Furthermore, our results have shown that, for most people, the T1 forms the boundary of the manubriotomy. We found that both the distance and angle differed significantly according to sex. A better understanding of the radiological anatomy of the surgeons' view line will help in the preoperative assessment of patients and in indicating an appropriate surgical approach.

Spine surgery has the potential to benefit from the use of three-dimensional (3D) printing technology (additive manufacturing), particularly in cases of complex anatomic diseases. Custom devices have the potential to reduce operative times, reduce blood loss, provide immediate stability, and improve fusion rates. ⋯ The use of patient-specific implants has reduced operative time significantly, which may offset costs of increased time spent preplanning the procedure. Surgical procedures can be preplanned using 3D models reconstructed from patient computed tomography and/or magnetic resonance imaging scans. Planning can be aided by 3D printed models of patient anatomy, which surgeons can use in training before performing complex procedures. When considering implants and prostheses, the use of 3D printing allows a superior anatomic fit for the patient compared with generic devices, with the potential to improve restoration of nonpathologic anatomy.

To evaluate surgical outcomes of homogeneous spinal-shortening axial decompression (HSAD) for reoperation in pediatric patients with tethered cord syndrome. ⋯ Outcomes of HSAD for revision surgery of tethered cord syndrome were satisfactory. HSAD improved neurologic function of patients significantly. HSAD could become an alternative surgical treatment of reoperation for tethered cord syndrome.

The development of postcraniotomy hematoma (PCH) after surgery for acute traumatic subdural hematoma (aSDH) has been associated with an increased risk of a poor outcome. The risk factors contributing to PCH remain poorly understood. Our aim was to study the potential risk factors for PCH in a consecutive series of surgically evacuated patients with aSDH. ⋯ The results suggest that alcohol inebriation at the time of injury and hypocapnia during hospitalization are risk factors for the development of PCH.

Patients with aneurysmal subarachnoid hemorrhage (aSAH) are at risk of the development of chronic shunt-dependent hydrocephalus. However, identification of shunt-dependent patients remains challenging. We sought to develop a prognostic model to identify patients with aSAH at risk of chronic shunt-dependent hydrocephalus. In addition to the well-known prognostic variables, blood clearance in the cerebrospinal fluid (CSF) spaces was considered. ⋯ Our prognostic model could help identify patients requiring permanent CSF diversion after aSAH, although additional modification and external validation are needed. Interventions aimed at accelerating the clearance of blood in the basal cisterns might have the potential to prevent the development of chronic hydrocephalus after aSAH.
