Postoperative shoulder imbalance (PSI) is a common complication of adolescent idiopathic scoliosis (AIS). However, results regarding risk factors for PSI are contradictory. This study was performed to explore the risk factors associated with PSI in AIS and determine whether PSI could be predicted. ⋯ To prevent PSI, we recommend sufficient correction of AVT of PTC and prevention of adding-on.

Review Case Reports
Posterior atlantoaxial dislocation without fracture or neurological symptoms treated by transoral-posterior approach surgery: a case report and literature review.
Atlantoaxial dislocation usually results from hyperextension trauma and is almost always accompanied by odontoid fracture and neurological symptoms. In most cases, patients with atlantoaxial dislocation die instantly. This is a rare report of posterior atlantoaxial dislocation without fracture and neurological symptoms effectively treated by transoral-posterior approach surgery, and only eleven similar cases have been previously reported. ⋯ Transoral-posterior approach surgery is a safe and effective way to manage irreducible posterior atlantoaxial dislocation.

Although thymic epithelial tumors (TETs) are rare, their spinal metastases are even rarer, and they have only been described in a few case reports. The aim of the present study is to discuss the possible treatments and outcomes of patients with spinal metastasis from TETs. ⋯ Radical surgery is associated with longer PFS, while PFS is associated with better OS. Postoperative radiotherapy seems to be a useful supplementary treatment after debulking surgery, and patients who respond to postoperative chemotherapy were demonstrated with greater OS. WHO type B3-C seemed to be an adverse factor for spinal metastasis from TETs. These slides can be retrieved under Electronic Supplementary Material.

Case Reports
Malignant triton tumor: Grand Round presentation of a rare aggressive case thoracolumbar spine tumor.
We report a rare and aggressive case of malignant triton tumor (MTT) at the thoracolumbar junction with foraminal extension mistreated as schwannoma. ⋯ Based on the Grand Round case and relevant literature, we present a case of a highly aggressive and fast-growing tumor with a very high local and distant recurrence. There is no consensus treatment plan available and patients usually die shortly after diagnosis.
