Ex vivo study of the mechanical performance of cylindrical and dual-core pedicle screws after insertion, removal, and reinsertion in the same hole. ⋯ Insertions and reinsertion of either cylindrical or dual-core pedicle screws have compromised insertion torque and pullout strength of the implants as measured by mechanical tests.

A case report. ⋯ TB should always be considered as a differential diagnosis of sacral lesions, and identifying multidrug resistance is equally important in its treatment. Lumbopelvic fixation is a safe and reliable option as it unloads the S1 segment by achieving fixation in the lumbosacral spine and iliac wings.
-
A retrospective review. ⋯ The use of wider intervertebral cages leads to a significantly lower rate of subsidence, but a longer cage does not necessarily offer a similar advantage. Wide cages are protective against subsidence, and the widest cages should be used whenever feasible for interbody fusion in the lumbar spine to protect indirect compression and promote arthrodesis.
-
A retrospective case series. ⋯ With the evolution of newer lower profile segmental implant systems that provide more rigid fixation and with the advancements in techniques for deformity correction, the repeat surgical intervention rate for idiopathic scoliosis has decreased.

Case Reports
Spondylodiscitis as a spinal complication of transrectal ultrasound-guided needle biopsy of the prostate.
A case report. ⋯ Acute pyogenic spondylodiscitis should be considered among the major complications of TUGNBP and may occur despite prophylactic antibiotic use.
