Sagittal balance is an important clinical parameter of the spine for its normal function. Maintenance of the sagittal balance is crucial in the clinical management of spinal problems. ⋯ This study showed that the imbalance in sagittal alignment might be responsible for disc degeneration and atraumatic vertebral fractures at the thoracolumbar regions, supporting clinical findings.

Atlantoaxial dislocation (AAD) is classified into reducible AAD and irreducible AAD (IRAAD). Anterior or posterior releasing followed by occipitocervical/atlantoaxial fusion is often performed for IRAAD, but is technically demanding. This study aimed to evaluate the results of the posterior open reduction technique without releasing the atlantoaxial joint in the treatment of potentially reducible AAD (PRAAD) caused by transverse ligament laxity in patients with rheumatoid arthritis (RA). ⋯ AAD with partial reduction after skeletal traction for 48 hours should be defined as PRAAD, not IRAAD. Open reduction with a C1-C2 pedicle screw-rod system can be safely and effectively applied in the treatment of PRAAD due to transverse ligament laxity in patients with RA.

A submammary approach to implanting pulse generators is innovative and has yielded good aesthetic results in the current literature. It was our aim to make a comparison of patient device acceptance, tolerance, and complications between submammary and abdominal device locations in deep brain stimulation. ⋯ SMI is a satisfactory alternative to other deep brain stimulation locations. SMI is a feasible option for any young woman who is eligible for deep brain stimulation.

Odontoidectomy may pose some risks for O-C1 and/or C1-C2 instability, with previous authors reporting techniques for endonasal C1-C2 fusion. However, no technique for endonasal O-C1 fusion currently exists. We sought to describe the feasibility of endonasal anterior C1 (AC1) screw placement for endonasal O-C1 fusion. ⋯ Navigation-assisted endonasal placement of AC1 screws is feasible. Additional studies should investigate the biomechanical stability of anterior C1 screw-plating systems, with anterior condylar screws as superior fixation point, compared to traditional posterior O-C1 fusion.

The objective of the study was to explore the significance of the distribution of lumbar facet joint effusion (unilateral or bilateral) and the amount of joint effusion in the process of lumbar degeneration. ⋯ A bilateral effusion signal is more likely to indicate lumbar instability than a unilateral effusion signal. The distribution width and area of effusion were positively correlated with lumbar stability and LSA.
