RESUMEN
OBJECTIVE: First, to propose a novel minimally invasive technique of full-endoscopic anterior odontoid fixation (FEAOF) that aims to reduce the risk of retropharyngeal approach (both open and percutaneous techniques) to anterior odontoid screw fixation. Second, to describe steps of the procedure and, lastly, to report the initial outcomes in patients treated with this novel technique. METHODS: Four non-consecutive patients who were diagnosed with a displaced odontoid fracture (Anderson-D'Alonzo classification type II and Grauer subclassification type A or B) from 2019 to 2020 underwent surgical fixation by our novel technique for anterior odontoid screw fixation. A detailed technical approach of FEAOF for the surgical treatment of type II odontoid fractures was described, and the patients' outcomes based on postoperative radiographic results including computed tomography (CT), clinical outcome parameters including visual analogue scale (VAS) for neck pain both preoperatively and at postoperative follow-up, and range of neck motion at the final follow-up were reported. RESULTS: The mean age was 33.5 years (24-41), three patients were male. The mean operative time was 93.75 min, and the mean blood loss was 7.5 ml. An immediate post-operative thin-sliced CT showed that all patients achieved satisfactory reduction and proper screw position. No screw malposition or penetration was found. At a 6-month follow-up, a thin-sliced CT demonstrated solid bony union in every case. The mean VAS for neck pain was reduced from 6.5 to 0.6 at the 6-months follow-up. At the final follow-up, all patients showed improvement in ranges of motion without any complications; however, one patient was lost to follow-up. CONCLUSIONS: FEAOF is a feasible and effective option for treating type II odontoid fractures. The procedure is less invasive than other techniques and provides clear direct visualization of the involved structures.

BACKGROUND: Chronic low back pain is a major social, economic and healthcare issue in the Thailand. Percutaneous techniques are rapidly replacing traditional open surgery in operations requiring discectomy, decompression and fusion. The percutaneous access to the disc was first used in the 1950s to biopsy the disc with needles. Percutaneous access to the disc using endoscopic techniques was developed in the 1970s. Nucleoplasty has emerged as one of the minimally invasive techniques for treatment of low back pain and lower extremity pain due to contained herniated discs which utilizes coblation technology for ablating and coagulating the nucleus for a partial disc removal. OBJECTIVE: Evaluate the effectiveness of Nucleoplasty on pain in activity and improvement in MRI in patients with radicular or axial low back pain secondary to contained herniated discs. DESIGN: Prospective, Randomized, Control Trial. MATERIAL AND METHOD: Sixty-four patients were randomized in two groups equally. Thirty-two patients had undergone Nucleoplasty and another thirty-two patients had undergone conservative treatment. Patients were evaluated at 1, 3, 6 and 12 months postoperatively and were asked to quantify their pain using a visual analog scale ranging from 0 to 10. Data were compared between baselines and at 1, 3, 6 and 12 months post-treatment. Pre-nucleoplasty MRI and Post-nucleoplasty 3 months were compared to evaluate the decrease of bulging disc. RESULTS: Reported pain and medication use were significantly decreased and functional status was improved at 1, 3, 6 and 12 months following Nucleoplasty (p-values < or = 0. 001 for all outcome measures at all time periods) and also the bulging disc was significantly decreased 3 months following nucleoplasty. CONCLUSION: Nucleoplasty appears to be safe and effective in Thailand. Is an effective procedure for patients presenting with discogenic back and/or radicular pain that have failed conservative therapies and are not considered candidates for open surgical interventions. A result of this analysis indicated that PDD using Coblation technology, also referred to as nucleoplasty, is an effective procedure for patients presenting with discogenic back and/or leg pain who have failed conservative therapies and are not considered candidates for open surgical interventions.
