Observational Study
Responsiveness and minimal important change of the NeckPix© in subjects with chronic neck pain undergoing rehabilitation.
The NeckPix© is a simple and rapid means of measuring the beliefs of subjects with chronic neck pain concerning pain-related fears of a specific set of activities of daily living. The original version showed satisfactory psychometric properties. This observational study is aimed at evaluating its responsiveness and minimal important changes (MICs) in subjects with chronic neck pain. ⋯ The NeckPix© was sensitive in detecting clinical changes in subjects with chronic neck pain undergoing rehabilitation. We recommend taking the MICs provided into account when assessing subjects' improvement or planning studies in this clinical context.

Multicenter Study Comparative Study
Comparison of pure lateral and oblique lateral inter-body fusion for treatment of lumbar degenerative disk disease: a multicentric cohort study.
The most effective interbody fusion technique for degenerative disk disease (DDD) is still controversial. The purpose of our study is to compare pure lateral (LLIF) and oblique lateral (OLIF) approaches for the treatment of lumbar DDD from L1-L2 to L4-L5, in terms of clinical and radiological outcomes. ⋯ LLIF and OLIF represent safe and effective MIS procedures for the treatment of lumbar DDD. LLIF had some risks of motor deficit and monitoring is mandatory, though it addressed more the coronal deformities. OLIF did not imply risks for motor deficits, but attention should be paid to vascular anatomy. It was more effective in kyphotic segmental deformities.

To present a novel posterior approach in multilevel cervical posterior decompression and fusion (PDF) using C2 pedicle screws that preserves the rectus capitis posterior major, oblique capitis inferior, and semispinalis cervicis. ⋯ This is potentially an effective approach for maintaining O-C2 ROM and rotational ROM, which enabled good levels of ADL after C2-T1 PDF. Axial pain and NDI were not worse after PDF.

The classification systems by Anderson and D'Alonzo, Effendi, Benzel and others have limitations when it comes to morphologically categorising fractures of the second cervical vertebral body (C2) that present with or without an additional fracture of the dens or with or without an extension of the fracture line into the vertebral arch and displacement. Currently, there are no definitive recommendations for the treatment of fractures at the junction of the dens with the vertebral body of C2 on the basis of outcome and stability data. Depending on patient anatomy, either anterior or posterior approaches can be used to fuse C1 and C2 and to achieve definitive surgical stabilisation. The anterior management of C2 fractures without C1-C2 fusion has the theoretical advantage that it preserves rotational motion at this motion segment and that the anterior approach is associated with lower morbidity. In the study presented here, we followed up a group of our patients who underwent anterior miniplate fixation for C2 fractures. ⋯ In patients with appropriate indications, anterior fixation with miniplates alone or additionally is a further useful treatment option in the management of fractures at the junction of the dens with the vertebral body of C2. Since this type of treatment preserves motion at the C1-C2 motion segment after fracture healing and since an anterior approach is associated with less surgical trauma than posterior instrumentation, the technique presented here should be included in a discussion on (surgical) treatment options.

Randomized Controlled Trial
Modified posterior percutaneous endoscopic cervical discectomy for lateral cervical disc herniation: the vertical anchoring technique.
During the long-term practice of percutaneous endoscopic cervical discectomy (PECD) at our institution, we have modified the protocol to include the vertical anchoring technique (VAT), which we will describe in detail in this article. The objective of this study was to compare the clinical outcomes associated with the conventional posterior PECD technique with that associated with the modified technique to determine the safety and efficacy of the latter technique. ⋯ Although the clinical outcomes of the two surgical techniques were similar, the VAT decreased the operative time and intraoperative fluoroscopy times in posterior PECD surgery. The learning curve for posterior PECD could be shortened by using the VAT. These slides can be retrieved under Electronic Supplementary Material.
