Multicenter StudyPostoperative segmental malalignment after surgery with the Bryan cervical disc prosthesis: is it related to the mechanics and design of the prosthesis?
In a radiographic study, postoperative segmental alignment was compared between 2 cohorts of 20 consecutive patients operated with a Bryan Cervical Disc Prosthesis. In group 2, patients with severe preoperative kyphosis were excluded for disc replacement surgery and the surgical technique was slightly altered to avoid asymmetric overdrilling of the posterior part of the cranial endplate of the caudal vertebral body. ⋯ This study shows that segmental malalignment with the Bryan Disc can be reduced and is therefore not device related. Proper patient selection and a modified surgical technique can prevent this adverse outcome.

Development of a computer-aided Cobb measurement method and evaluation of its reliability. ⋯ Compared with the documented results, variability of the Cobb measurement is reduced by using the developed computer-aided method. This method can help orthopedic surgeons measure the Cobb angle more reliably during scoliosis clinics.

Percutaneous endoscopic discectomy: clinical results and how it affects the quality of life.
Prospective study ⋯ Endoscopic discectomy is associated with improvement in back pain and lower-limb symptoms postoperation which translates to improvement in quality of life. It has the advantage that it can be performed on a day case basis with shorter length of hospitalization and early return to work thus improving quality of life earlier.

Comparative StudyBiomechanical comparison of 4 fixation techniques of sacral pedicle screw in osteoporotic condition.
An in vitro biomechanical cadaver study. ⋯ PMMA augmentation can increase the bonding strength of sacral screw-bone interface and the sub-endplate PMMA augmented sacral screw could obtain the highest stability among the 4 fixation techniques in osteoporotic condition.

Variability in techniques and patient safety protocols in discography: a national multispecialty survey of International Spine Intervention Society members.
National survey. ⋯ Discography is being performed by multiple different specialties: Anesthesiology, PMR, Radiology (highest to lowest in number, respectively). Overall adherence to guidelines pertaining to infection control was fair except for double needle technique which was poor. Adherence to guidelines that affect the diagnostic value was poor. There is specialty variation in adherence to guidelines and to a lesser extent volume based effect on compliance.
