Conservative management of Anderson Type II odontoid fractures in octogenarians: is radiological union what we are searching for?

OBJECTIVE: The C2 odontoid fractures represent one of the most common cervical spine injuries. Stabilization and immobility are required for a correct treatment. However, in some cases surgical treatment is recommended. There are still no guidelines for Type II odontoid fractures management. The present study aims at determining how non-union could impact on mortality, functional and clinical outcomes in octogenarian patients conservatively treated. MATERIALS AND METHODS: The present investigation is a retrospective case series. All patients with diagnosis of Type II odontoid fractures, over 80 years and conservatively treated in our institution between January 2016 to April 2020 were potentially eligible for the study. The primary outcome was the bony fusion of the fracture after 3 months of conservative treatment. The secondary outcomes were clinical, functional outcomes and mortality. RESULTS: Sixty-four patients were eligible for the study according to inclusion and exclusion criteria. Computer Tomography (CT) evaluation performed 3 months after trauma showed complete fracture healing in 31 patients (48.4%, Fused), while 33 patients (51.6%) were evaluated as non-fused. Among these, 6 months after the CT evaluation, 14 patients were classified as stable, while 19 were classified as unstable. There were no statistically significant changes in clinical and functional outcomes reported in our patient series between patients with complete radiological healing and patients who reported stable fibrous non-union. CONCLUSIONS: In a selected group of elderly patients with a high risk for surgery, the conservative treatment of odontoid Type II fractures can be considered a viable management strategy. The achievement of a stable non-union allows for clinical and functional results comparable to complete fracture healing.

The Feasibility of Long-Segment Fluoroscopy-guided Percutaneous Thoracic Spine Pedicle Screw Fixation, and the Outcome at Two-year Follow-up.

Introduction: Posterior percutaneous instrumentation may represent a challenge when multiple levels need to be instrumentated, especially when including the upper thoracic spine. The aim of the present study was to evaluate the technical feasibility and the long-term outcome of such long constructs in different surgical conditions. Materials and Methods: This investigation was a retrospective cohort study which included patients who underwent thoraco-lumbar percutaneous fixations. We collected clinical, surgical and radiological data, with a minimum follow-up of 24 months. Health-related quality-of-life, residual pain, instrumentation placement, and complications were studied. Results: A total of 18 procedures were enrolled, in which 182 screws were implanted, (170 positioned in thoracic and 12 in lumbar pedicles, respectively). No surgical complications or hardware failure occurred in our series, 6 out of 182 (3,2%) screws had a partial pedicle breach, without neurological impairment or need for surgical revision. Conclusion: According to our results, a fully posterior percutaneous approach for long thoraco-lumbar spine instrumentation can be considered safe and reproducible, although an adequate training is strictly required.

Paracetamol-codeine compared to ketorolac for pain control in the Emergency Department.

OBJECTIVE: Paracetamol /codeine has shown a strong analgesic activity in several studies conducted among different kind of subjects, including those with trauma. Nevertheless, its efficacy in patients accessing the Emergency Department (ED) for different kind of pain has never been tested. PATIENTS AND METHODS: This is a cross-sectional, observational, prospective, cohort study. Inclusion criteria were patients > 18 year old presenting to the ED for localized traumatic or inflammatory pain involving only extremities. Numeric scale (NRS) was recorded thirty minutes and two hours after the administration of the analgesic therapy, consisting of 15 mg of ketorolac or 1000 mg/60 mg of paracetamol/ codeine, both orally. RESULTS: Two-hundred patients were consecutively enrolled; 87 were treated with paracetamol/codeine and 113 with ketorolac. The combination paracetamol/codeine resulted to be not inferior to ketorolac in non-traumatic pain group and trauma group (p = 0.635 and p = 0.482, respectively). Compared to ketorolac, the combination paracetamol/codeine exerted a significantly higher analgesic activity in patients with fractures and muscular pain (p = 0.044) and was more effective in acute pain (p = 0.002), with a significant effect two hours after the administration (p = 0.029). CONCLUSIONS: Paracetamol/codeine is equivalent to ketorolac in non-traumatic pain and post-traumatic pain, but is superior in acute pain and in patients with fractures and muscular pain. Those results play in favor of the use of the combination paracetamol/codeine in patients accessing the ED for non-traumatic or traumatic pain of the extremities.

Ultrasound detection of foreign body and gas contamination of a penetrating wound.

We report a case in which ultrasonography (US) examination was used in the Emergency Department to reveal and diagnose gas contamination of a penetrating wound. Air microbubbles are extremely small and their typical distribution and movement are like those of "sparkling-wine microbubbles". US assessment of spontaneous disappearance of the air bubbles can distinguish a harmless traumatic nature of the wound from a life-threatening gas-producing bacterial infection.
