Comparative Study
Analysis of retrieved growth guidance sliding LSZ-4D devices for early onset scoliosis and investigation of the use of nitinol rods for this system.
Analysis of volumetric wear loss of retrieved growth guidance sliding devices LSZ-4D for treatment of early onset scoliosis and laboratory in vitro wear test for comparison of wear resistance of alloys Nitinol, Ti, and cobalt chromium (CoCr). ⋯ Application of wear-resistant coatings on Ti components in growth guidance sliding devices for the treatment of early onset scoliosis will be useful. High wear resistance of Nitinol combined with its superelastic and shape memory properties could make application of Nitinol rods for spinal instrumentation beneficial.

Systematic review. ⋯ There is a small but rapidly growing body of US-based CUA in spine care. The quality of CUA evidence is variable but there are significant opportunities to strengthen future CUA studies in spine. This study highlights the need for more attention to CUA research and the quality of these studies in spine care.

Prospective study. ⋯ The mJOA is a useful tool in the assessment of cervical spondylotic myelopathy and it should be adopted as the standard for evaluating functional status in this population.

A retrospective case series. ⋯ Scoliosis Research Society patient questionnaire-22 scores and radiographical parameters other than the correction rate were equivalent between the 2 groups. A short fusion strategy, in which the upper instrumented vertebra is 1-level caudal to the upper EV, is applicable to posterior correction and fusion surgery with pedicle-screw constructs for Lenke type 5C curves.
