Emergency Treatment of Cervical Vertebromedullary Trauma: 10 Years of Experience and Outcome Evaluation.

OBJECTIVE: The aim of the study is to identify and validate, through the recording of clinical and radiological data, the different surgical approaches and treatments valid for most subaxial cervical dislocation fractures and whether there is an advantage from using an anterior approach rather than a posterior approach and conversely.. MATERIAL AND METHODS: A retrospective study was carried out analyzing the case history of the last 10 years of vertebromedullary traumas treated at the spine surgery unit of the Policlinico Gemelli in Rome. Data on surgical timing, American Spinal Injury Association (ASIA) scores for neurological damage, and subsequent assessments on recovery, survival, and mortality were also examined. RESULTS: A total of 80 patients were treated: 50 by the posterior approach, 24 by the anterior approach, and six by the double approach. Our average follow-up time was 4.2 years. A prevalence of surgery with the posterior approach was noted. We observed the worsening of cervical kyphosis about 15 months after the trauma in two cases treated with the posterior approach alone. A second surgical treatment was performed in these patients. One of these patients underwent an anterior fusion; the other case underwent a posterior revision because the patient had ankylosing spondylitis. Although we found no statistically significant difference in outcomes between the various surgical treatments, in this retrospective study, we analyzed the characteristics and outcomes of cervical spine injuries that required surgical treatment. CONCLUSION: The aim of surgery in unstable cervical spine injuries should be to reduce and stabilize the damaged segment, maintain lordosis, and decompress when indicated. The optimal choice of surgical approach and treatment, or its superiority in terms of outcomes, remains a debated issue.

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.

Unusual Posterior Epidural Migration of Intervertebral Herniated Disc: A Report of Two Cases.

Disc herniation is one of most common causes of spine surgery. Because of the presence of posterior longitudinal ligaments, disc fragments often migrate into the ventral epidural space. A posterior epidural herniation of a disc fragment is a rare occurrence. We report two cases of posterior migrated disc fragments, with, radiological and clinical findings. Because of the rarity of a posterior migration of the intervertebral disc fragments, a differential diagnosis can be challenging. This painful syndrome associated with neurological lower limb deficits can be confused initially, with other posterior epidural space-occupying lesions such as tumours, abscess or hematomas. A gadolinium-enhanced MRI scan is the gold standard for a correct diagnosis. Early surgical decompression of the spine with a posterior approach remains the optimal technique in ensuring the best possible outcome for the patient.

Kyphoplasty vs conservative treatment: a case-control study in 110 post-menopausal women population. Is kyphoplasty better than conservative treatment?

OBJECTIVE: Osteoporosis is a highly prevalent disease worldwide. Consequences of vertebral osteoporotic fractures include pain and progressive vertebral collapse resulting in spinal kyphosis, decreased quality of life, disability and mortality. Minimally invasive procedures represent an advance to the treatment of osteoporotic VCFs. Despite encouraging results reported by many authors, surgical intervention in an osteoporotic spine is fraught with difficulties. Advanced patients age and comorbidities are of great concern. PATIENTS AND METHODS: We designed a retrospective case-control study on 110 post-menopausal women consecutively visited at our institution. Study population was split in a surgical and a conservative cohort, according to the provided treatment. RESULTS: Kyphoplasty treated patients had lower back pain VAS scores at 1 month as compared with conservatively treated patients (p < 0.05). EQ5D validated questionnaire also showed a better quality of life at 1 month for surgically treated patients (p < 0.05). SF-12 scores showed greater improvements at 1 month and 3 months with statistically significant difference between the two groups just at 3 months (p < 0.05). At 12 months, scores from all scales were not statistically different between the two cohorts, although surgically treated patients showed better trends than conservatively treated patients in pain and quality of life. Kyphoplasty was able to restore more than 54.55% of the original segmental kyphosis, whereas patients in conservative cohort lost 6.67% of the original segmental kyphosis on average. CONCLUSIONS: Kyphoplasty is a modern minimal invasive surgery, allowing faster recovery than bracing treatment. It can avoid the deformity in kyphosis due to VCF. In fact, the risk to develop a new vertebral fracture after the first one is very high.

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.

Cauda equina syndrome: evaluation of the clinical outcome.

AIM: Cauda equina syndrome is a rare but highly impairing syndrome involving lower limbs as well as urinary, defecatory and sexual function. In the literature the most investigated sphincter dysfunction is the urinary. Bowel and sexual function are often overlooked since they become more relevant after the acute phase. PATIENTS AND METHODS: Eight consecutive male patients affected by cauda equina syndrome with sphincter dysfunction due to herniated disc disease of lumbar spine were treated between 2007 and 2009. Five patients were followed-up for at least two years. Sexual function was evaluated by IIEF-5 questionnaire; bowel function was investigated by means of clinical and instrumental investigation and manometry. RESULTS: Although little clinical improved, patients still complained severe symptoms at first year follow-up while all but one improved significantly in the following year. At two years follow-up only the patient whose cauda equina syndrome was misdiagnosed and surgically treated late respect to the onset of the syndrome, complained a persistent severe sexual and bowel dysfunction. CONCLUSIONS: Our results show that a long-term follow-up is mandatory to evaluate the real outcome of surgical managed cauda equine syndrome because short-term evaluation could be misleading about the residual capacity of late neurologic improving. Despite the relatively low number of cases evaluated, our results confirm that early diagnosing and treating the syndrome are relevant for the final outcome.

Relevance of the cranioaxial angle in the occipitocervical stabilization using an original construct: a retrospective study on 50 patients.

We present a retrospective study on a series composed of 50 patients, treated between 1992 and 2006, affected by pathologies of the craniocervical junction. All the patients were treated using an innovative procedure based on a cranial claw made up of low profile hooks, conceived by one of the authors. Advantages of this technique are, to our point of view, a higher resistance to cranial hooks dislodgment, when compared with screw fixation instrumentation, especially in pathological conditions, such as rheumatoid arthritis that leads to a qualitative deterioration of the bone stock and to the reduction of the occipital wall thickness. Occipitoaxial alignment was assessed radiographically using the McGregor line. We observed an improvement in the subjective evaluation of pain in all treated patients with a 46% improvement from the initial values. Moreover, patient stabilized with an occipitoaxial angle included in the physiological range showed better results either for the survival of the instrumentation or the onset of junctional pathology. Patients have been followed up afterwards and evaluated by the visual analogue scale for the assessment of pain and by the Nurick scale for the cases associated with myelopathy. We believe that cranial anchorage with a hook claw allows for an instrumentation provided with high stability, particularly useful in revision surgery and major instabilities. The study of the occipitoaxial angles showed that the better results and the long-lasting stability of the implant are correlated to a fusion angle included in the physiological range.

Cervical spondylotic myelopathy: proposal of a surveillance algorithm.

The review of the publications concerning cervical spondylotic myelopathy (CSM) suggests that it has not been achieved a clear consensus about the treatment of this pathology. In this paper an algorithm of surveillance, conceived as an assistant tool to decide the best indications of treatment is presented. The algorithm permits a clear separation of the symptomatic patients on the base of the presence or the absence of neurologic damage resulting at the evoked potentials examination. The negativity of the evoked potentials, that means neurologic integrity, excludes any type of surgical treatment. In case of proved neurologic damage, the algorithm permits a further differentiation in subgroups according to the degree of clinical disability. If evoked potentials are positive, a surgical decompression should be always performed in patients affected by a severe clinical disability. The group of patients affected by a mild degree of clinical disability but with positive evoked potentials represents the most challenging for the spinal surgeons. Actually, several studies support either surgical and non surgical treatment for these patients. Although the Authors think that a surgical decompression has to be always performed in case of proved neurologic damage, only further randomized studies based on accurate algorithms could elucidate the outcome of the CSM and could permit to choose the best treatment according to the degree of the disease.

Percutaneous fixation of mallet fractures by the "umbrella handle" technique.

Over a period of 8 years, 48 fingers with mallet fractures of Wehbé and Schneider Types 1 and 2, subtypes B and C, were treated in 31 men and 17 women of mean age 42 (range 17-61) years. The fractures included 5 Type 1 subtype B, 2 Type 1 subtype C, 23 Type 2 subtype B and 18 Type 2 subtype C fractures. The technique used consisted in passing a K-wire percutaneously from dorsal to volar and pinning the fracture fragment while leaving the distal interphalangeal joint free to allow immediate postoperative mobilisation. Fracture splintage was removed at 6 weeks. The results at 8 weeks, which remained unchanged at 12 months in 46 fingers, were assessed as excellent in 11, good in 35 and fair in two cases by the Crawford rating system. One case of pin track infection required early removal of the pin.
