Reprint of: Thoracolumbar burst fractures associated with incomplete neurological deficit in patients under the age of 40: Is the posterior approach enough? Surgical treatment and results in a case series of 10 patients with a minimum follow-up of 2 years.

INTRODUCTION: Surgical management of thoracolumbar burst fractures is controversial. While the goals of surgical treatment are well accepted (i.e., fracture reduction and stabilization, neural elements decompression, and segmental angular deformity correction), the choice of the best surgical approach (i.e., posterior vs. anterior vs. combined approach) remains controversial. Several studies have debated the advantages of each surgical approach but there is no definitive evidence available to date, particularly in young adult patients. The aim of this study was to assess whether posterior approach alone can be a valid surgical treatment for patient under the age of 40 affected by thoracolumbar burst fractures and incomplete neurological deficits. MATERIAL AND METHODS: A total of 10 consecutive patients affected by thoracolumbar burst fractures associated with incomplete neurological deficits treated at our institution from January 2015 to February 2017 were included in our study. All patients were under the age of 40 at the time of injury and underwent decompression and stabilization using the posterior surgical approach alone. Demographics, clinical, and radiographic parameters were recorded preoperatively, postoperatively and at the latest available follow-up. The minimum follow-up was set at 2 years post-operatively. RESULTS: The mean operative time was 303.6 min (range, 138-486). Average blood loss was 756 mL (range, 440-2100). Nine out of ten patients returned to a normal neurological status after surgery while 1 patient showed some improvement but did not recover completely. Segmental kyphotic deformity improved from a mean of 21.8° before surgery to 14.8° at the time of the last follow-up. The anterior and posterior wall height of the fractured vertebra was restored with an average of 4 mm. The Visual Analogue Scale score reported an improvement from the mean preoperative value of 7.92 to 1.24 at the last follow-up; 8 out of 10 patients resumed physical activity while all of them returned to work. CONCLUSIONS: A single posterior surgical approach is an acceptable option in terms of clinical, radiological and functional outcomes at 2 years follow-up in patients under the age of 40 presenting with a thoracolumbar burst fracture and neurological deficit.

Minimally invasive surgery for the treatment of thoraco lumbar pyogenic spondylodiscitis: indications and outcomes.

OBJECTIVE: Pyogenic spondylodiscitis (PS) is a non-specific infection affecting intervertebral disks and adjacent vertebral bodies. Once considered a rare condition in developed countries, the incidence of PS has been increasing alarmingly and still represents a challenge for clinicians and orthopedic surgeons. New minimally invasive techniques have been proposed but the proper indications for these different approaches remain controversial. The aim of this study was to describe the available minimally invasive surgical techniques and to evaluate their proper indications through a review of recent literature. MATERIALS AND METHODS: Over 30 articles of recent scientific literature have been reviewed and analyzed. Studies were searched through the PubMed database using the key words: spondylodiscitis, minimally invasive, and surgical treatment. The most interesting and valid techniques and results have been reported. Despite the exclusion of case reports, all the available studies have been conducted on small groups of patients. Indications for each technique have been reported according to a clinical-radiological classification of PS. RESULTS: Six of the most widely used minimally invasive surgical techniques have been described.  High success rates have been reported in terms of preventing the progression of spondylodiscitis into more destructive forms, reduction of time and operative hospitalization, faster pain relief, early mobilization, and achievement of microbiological diagnosis. CONCLUSIONS: The role of minimally invasive surgery in the treatment of PS is rapidly expanding. Reducing surgery-related morbidity in these frail patients is possible and often necessary. However, while more and more new techniques are being proposed, still few clinical data are available. Clinical comparison studies with open traditional surgery should be encouraged, and more attention should be paid to long-term outcomes. For the present, the indications for minimally invasive procedures should, therefore, be evaluated on a case by case basis and on clinical and radiological findings.
