Comparative StudyBiomechanical comparison of anterior lumbar interbody fusion and transforaminal lumbar interbody fusion.
An in vitro biomechanical comparison of 2 fusion techniques, anterior lumbar interbody fusion (ALIF) and transforaminal lumbar interbody fusion (TLIF), on cadaveric human spines. ⋯ Both ALIF and TLIF procedures combined with posterior instrumentation significantly improved construct stability of intact spinal motion segments. However, there was no statistical difference between these 2 fusion techniques. The 2 ALIF approaches (lateral and anterior) also had similar construct stability even though anterior longitudinal ligament severing significantly reduced stability.

Radiation exposure to the surgeon and the patient during kyphoplasty.
Prospective study of patients who underwent single or multilevel kyphoplasty for vertebral fractures. ⋯ Without eye or hand protection, the total radiation exposure dose to these areas would exceed the occupational exposure limit after 300 cases per year. Surgeons should wear lead lined glasses and keep their hands out of the radiation beam.

Clinical TrialMinimally invasive transpedicular vertebrectomy for metastatic disease to the thoracic spine.
We present a series of 8 patients with thoracic metastatic disease causing acute neurologic decline. We present minimally invasive posterolateral vertebrectomy and decompression as an effective approach in patients with significant comorbidities and as palliative care. ⋯ Minimally invasive transpedicular vertebrectomy is an effective palliative treatment option for thoracic metastatic disease in patients not eligible for more extensive anterior transthoracic surgery and stabilization.
