The most common site is the lower levels of the subaxial cervical spine. The goal of early decompression and reduction is to mitigate secondary injury, at the expense of increasing spinal canal diameters and decreasing edema, ischemia, and their inflammatory mediators. For this, the reduction methods, closed and open,(1) are proposed; the selection of one or the other is a controversial issue.  Closed reduction aims to return the canal to its anatomical dimensions, achieving normal alignment. Two requirements are accepted for its performance: pharmacological relaxation and an optimal state of consciousness of the patient, which allows communicative feedback with the surgeon.(1) If the reduction is late, it is often unsuccessful. As if there is no fracture of the joint capsules, or they are "blocked", which would require excessive weight.(2)  Closed reduction can fail in half of the cases, as shown by a meta-analysis published by Keppler et al.(3) that included 368 patients from 11 studies. In contrast, open reduction was achieved in almost 95 % of cases.     LETTER TO EDITOR  Horta Tamayo EE, et al.    ISSN: 1561-3194   RNPS: 1877 Rev Ciencias Médicas. 2023; 27(2023):  e5967       www.revcmpinar.sld.cu Página2                                                       LETTER TO EDITOR CC-BY-NC 4.0  Regarding its safety, the incidence of permanent neurological complications is very low, generally 1 %.(2)   However, even after successfully achieving a closed reduction, the patient must receive surgery to stabilize the affected vertebral segment, which leads many to prefer its use just before surgery.(4) Another drawback with this proceed, is the need for clinical-radiological monitoring during its performance.(5)  Many researchers suggest obtaining MR images before closed reduction (single sagittal T2 sequence in order to reduce the time it takes),(2) which is accompanied by an added risk when mobilizing and delays in surgical treatment. The availability of performing this study is very limited in low-income countries.(4)  In 2018, the Spine Section of the German Society for Orthopedics and Trauma, recommended closed reduction by specialized personnel, under fluoroscopic control, as soon as possible. If it failed, he proposed to do an open reduction by anterior approach. In the case of initial selection of a posterior route, it is a requirement to obtain a prior MRI.(6)  Taking a similar position, in 2020, the World Federation Neurosurgical Societies Spine Committee recommended early closed reduction by traction, except if the patient is unconscious. If closed reduction fails, they suggest immediate open reduction.(2)  With respect to open reduction, there are two fundamental opinions: those who prefer it initially and those who perform it after the failure of closed reduction.(2) In neurologically intact patients, the first option is recommended.(6)  Subsequent to this step, the applicability of the anterior approach for surgical decompression is well accepted.(4) During this approach, Caspar's vertebral pins, or Cloward-type retractors, can be used to apply distraction forces and release locked facets in the most cases. Rarely may alignment not be achieved in this way. If so, a posterior approach would be necessary.(1,2,5)  Some authors have published that cases with incomplete motor lesions have shown a higher rate of success for closed reduction,(7) suggesting that patients with total motor deficit should receive initial surgical treatment.(2,7)  However, it is logical to infer that the greater the translation, the more spinal cord deformation and more neurological involvement. In addition, the time spent in the procedure to achieve correct alignment was not taken into account (from three to 10 minutes between each progressive increase in weight, starting with 4,5 kg up to a maximum of 60 kg),(5) therefore considering its low success rate compared to open reduction,(2) it may be a lost vital time.  There are no cohort studies in the region on the use of closed or open reduction techniques. Cuba does not escape this scenario. In our country, although there are spinal surgery centers in the 14 provinces and the special municipality, scientific reports on cervical fractures are scarce. Nevertheless, a rapid transfer of these patients to specialized centers, and stabilization and decompression surgery is carried out early (before the first 24-48 hours of the trauma) regardless of the degree of neurological injury (complete or incomplete). On the other hand, obtaining MR images in the context of a traumatic spinal cord injury is really anecdotal, typical of low-income countries.(4)    Horta Tamayo EE, et al.    ISSN: 1561-3194   RNPS: 1877 Rev Ciencias Médicas. 2023; 27(2023):  e5967       www.revcmpinar.sld.cu Página3                                                       LETTER TO EDITOR CC-BY-NC 4.0  If we take into account the superiority shown by the anterior versus the posterior approach, in order to maintain alignment,(3) we consider that closed reduction would be objectively relegated, in our case, to pre-surgical use. However, in those exceptional situations where there is a delay in fixation surgery (availability of implants, associated injuries, etc.) would have an added value, allowing a restitution of space, until the patient receives the definitive surgical intervention.
