RESUMO

This retrospective case series of prospective data aims to describe the transaxillary approach for the treatment of upper thoracic spine pathology. Various surgical techniques and approaches have been reported across the literature to address upper thoracic spine pathology, including the cervicothoracic approach, anterior transsternal approach, posterolateral approach, supraclavicular approach, and lateral parascapular approaches. These techniques are invasive. A minimally invasive, less morbid, and direct access approach to the pathology of the upper thoracic spine has not been reported in the literature. Patients with pathology affecting the first thoracic vertebra up to the sixth thoracic vertebra were classified into the upper thoracic spine group. Patients with pathology below the sixth thoracic vertebra were excluded. Patients not having a minimum follow-up of 12 months were also excluded. The study analyzed 18 patients. The mean preoperative modified Japanese Orthopedic Association score was 7.2±1.44, which improved to 10.16±1.2 (p<0.05). The majority (14/18) of the patients had an excellent outcome. Three patients had good outcomes, and one patient had a fair outcome. Five cases of intraoperative dural leak were recorded, and one patient had postoperative neurological deficit. The transaxillary approach is a safe, viable, muscle-sparing, and minimally invasive approach for ventral pathologies of the upper thoracic spine.

RESUMO

BACKGROUND: The treatment of Kummell disease remains controversial, with a wide variety of options proposed in the literature. This study aims to introduce a unique and minimally invasive approach for the treatment of Kummell disease and present the clinical results of this technique. METHODS: Twenty patients underwent surgery using the minimally invasive surgery transpedicular intrabody cage (MISTIC) technique from 2014 to 2016. Postoperatively, patients were seen at 3, 6, and 12 months after surgery. Visual analog scale and Oswestry Disability Index scores were collected, and patient outcomes were graded according to the modified MacNab's criteria. Radiological outcomes were assessed through measurements of the anterior vertebral height (AH), mean vertebral body height (BH), and segmental angle (SA) on standing lateral radiographs pre- and postoperatively. RESULTS: There was significant improvement in the SA, AH, and BH postoperatively. The SA improved from 15.2 ± 8.7° of kyphosis to 1.2 ± 5.2° (P < 0.01) in the immediate postoperative period. The AH increased from 13.3 ± 14.6 to 22.6 ± 12.2 mm (P < 0.01), and at the final follow-up, it was 21.9 ± 12.6 mm (P < 0.01). Similarly, the BH increased from 18.5 ± 6.8 to 25.6 ± 7.6 mm (P < 0.01) postsurgery, and at the final follow-up, it was 23.6 ± 4.4 mm (P < 0.01). CONCLUSIONS: The MISTIC technique offers significant correction of kyphosis and restoration of the vertebral anatomy following surgery. These results were maintained at 12 months postoperation, with a 100% union rate of the fractures. Additionally, patients experienced significant pain relief and improvement in their ODI scores that were maintained at 12 months.

RESUMO

Key clinical message: Spinal cord herniation is an uncommon diagnosis. There should be a high index of suspicion to diagnose spinal cord herniation when a patient presents with incomplete neurological deficits. Surgical repair of the hernia can have postoperative complications with new neurological deficits and they should be considered during the treatment. Abstract: A 37-year-old male presented with insidious onset upper back pain and altered sensations of pain and temperature over the right half of the body below the nipple for 2 months. MRI of the thoracic spine showed an anterolateral defect (left) at the level of T2-T3 vertebra. The defect was covered by a dural graft and the wound was closed with a drain On the 3rd postoperative day, neurological weakness progressed to paraplegia. Patient was treated by exploration and decompression of the hematoma. The deficits were completely recovered at one-month follow-up. Patients with spinal cord herniation and neurologic deficits when treated timely have good outcomes.
