Migration of thoracic aorta after the anterior correction of thoracic idiopathic scoliosis without parietal pleura closure.
To compare the preoperative and postoperative relative position of the thoracic aorta to the vertebrae in patients with idiopathic scoliosis (IS) after anterior corrective surgery without parietal pleura closure. ⋯ The thoracic aorta in patients with predominant right thoracic IS migrated posterolaterally relative to the vertebral body after anterior surgery without parietal pleura closure.

Lateral transpsoas interbody fusion (LTIF) with plate fixation and unilateral pedicle screws: a preliminary report.
Retrospective cohort study. ⋯ We report a series of patients treated with unilateral pedicle screw fixation with LTIF. Although the patient cohort is small, validated outcomes instruments were used and fusion was assessed by computed tomography scan in most cases. The data suggest that unilateral pedicle screw fixation may be adequate to achieve high fusion rates after LTIF surgery using anterior instrumentation. Applying this technique in patients with osteoporosis may lead to a significant risk of postoperative vertebral body fracture.

Evaluation of lumbar total disc arthroplasty (TDA) in military patients. ⋯ This study showed clinical success approaching 80% in military patients who underwent lumbar TDA. Furthermore, close to 70% were able to return to their positions within the military. TDA, while more closely reapproximating the normal biomechanics of the spine, may provide patients with an improved alternative to spinal arthrodesis for degenerative disc disease.

Posterior-only approach with selective segmental TLIF for degenerative lumbar scoliosis.
Forty-six patients with degenerative lumbar scoliosis, and treated with selective segmental transforaminal lumbar interbody fusion (TLIF), were studied retrospectively. ⋯ Selective segmental TLIF is helpful in correcting lumbar lordosis, segmental deformity, and translation, and thus obtaining satisfactory outcome in the treatment of degenerative lumbar scoliosis.

Review Case ReportsMinimal invasive anterolateral transthoracic transpleural approach: a novel technique for thoracic disc herniation. A review of the literature, description of a new surgical technique and experience with first 12 consecutive patients.
A retrospective review of a case series. ⋯ Anterior decompression using a transthoracic transpleural approach provides excellent exposure and allows consistent decompression of thoracic disc herniations. This study demonstrated that a new minimally invasive, transthoracic transpleural decompression technique can be safely performed for single-level thoracic disc herniations. The early results showed that this technique allows less dissection, along with the advantages of conventional thoracotomy.
