The Effect of Cervical Paravertebral Extensor Degeneration on Sagittal Alignment and Functional Status of Cervical Spine in Patients With Cervical Spondylotic Myelopathy.

Study Design: This was a cross-sectional study.

Objective: The objective of this study was to assess cervical paravertebral extensor degeneration in patients with cervical spondylotic myelopathy (CSM) and its impact on the sagittal parameters and functional status of the cervical spine.

Summary Of Background Data: Paravertebral extensor degeneration is well-studied in CSM; however, the effect of extensor degeneration on the sagittal balance and functional status of the cervical spine is unclear.

Three-dimensional navigation (O-arm) versus fluoroscopy in the treatment of thoracic spinal stenosis with ultrasonic bone curette: A retrospective comparative study.

Three-dimensional intraoperative navigation (O-arm) has been used for many years in spinal surgeries and has significantly improved its precision and safety. This retrospective study compared the efficacy and safety of spinal cord decompression surgeries performed with O-arm navigation and fluoroscopy. The clinical data of 56 patients with thoracic spinal stenosis treated from March 2015 to April 2017 were retrospectively analyzed.

Radiological characteristics and anatomical risk factors in the evaluation of hallux valgus in chinese adults.

Background: There are no unified theories as to the anatomical changes that occur with hallux valgus, we investigated the radiological characteristics and anatomical risk factors for hallux valgus deformity in Chinese adults.

Methods: We reviewed 141 patients with hallux valgus (206 feet; 15 males, 126 females; mean age, 58.5 years).
