OBJECTIVE@#To compare the clinical effects of total laminectomy with lateral mass screw fixation and single open-door laminoplasty in the treatment of cervical spinal cord injury without fracture and dislocation.@*METHODS@#The clinical data of 75 patients with cervical spinal cord injury without fracture and dislocation treated from December 2014 to April 2020 were retrospectively analyzed, including 65 males and 10 females, aged from 33 to 83 years old with an average of (60.1±11.4) years. According to surgical method, the patients were divided into observation group (36 cases) and control group (39 cases). The observation group was treated with C3-C6 single open-door laminoplasty. In the control group, the C3-C6 whole lamina was opened by "uncovering", and the lateral mass screw was fixed and fused. The general conditions including operation time, intraoperative blood loss, hospital stay and complications such as axial pain, cerebrospinal fluid leakage, postoperative C5 nerve palsy were recorded. Visual analogue scale(VAS), Nurick pain scale, Japanese Orthopaedic Association(JOA) scores and American Spinal Injury Association(AISA) injury scale were used to evaluate the improvement of clinical symptoms and related functional recovery 12 months after operation.@*RESULTS@#There were no statistically significant differences in operation time, intraoperative blood loss and hospital stay between two groups(P>0.05). There were statistically significant differences in JOA, VAS, ASIA and Nurick scores of the all patients between 12 months after surgery and before surgery (P<0.05), and there was no significant difference between groups. There was significant difference in the incidence of C5 nerve root palsy and axial pain between two groups(P<0.05), but there was no significant difference in the complications of cerebrospinal fluid leakage between two groups (P>0.05).@*CONCLUSION@#Total laminectomy with lateral mass screw fixation and single open-door laminoplasty in treating cervical spinal cord injury without fracture and dislocation can obtain satisfactory results in restoring nerve function, alleviating pain and improving daily behavior, but single open-door laminoplasty has the advantages of less trauma and low incidence of complications.

Los quistes aracnoidales espinales son lesiones poco comunes en la población pediátrica. La mayor parte de ellos, se ubican en los segmentos dorsales y la posición anterior respecto a la médula es rara en todos los casos. Si bien su patogenia no está aclarada, se han asociado a defectos del tubo neural y traumas previos. Clínicamente, pueden presentarse con síndrome medular que en ocasiones pueden empeorar con cambios posturales. El tratamiento, puede ser conservador o quirúrgico, el que está indicado en presencia de síntomas neurológicos secundarios a compresión medular, siendo el abordaje posterior el más frecuentemente utilizado. El propósito de la cirugía es la resección total o en su defecto, la fenestración del quiste para comunicarlo al espacio subaracnoídeo. Una potencial complicación de la vía posterior, es la herniación medular durante la durotomía, secundaria al efecto compresivo del quiste, la cual podría aumentar la morbilidad neurológica en el período postoperatorio. Se presentan 2 casos consecutivos en edad pediátrica con quistes intradurales espinales anteriores, el primero en la región cervico-dorsal cuya cirugía se vio dificultada por la presencia de herniación medular transdural y un segundo caso con un quiste exclusivamente cervical, en que mediante una punción lateral del quiste guiada por ecografía previo a la durotomía, se logró resecar la lesión sin esta complicación.

Spinal arachnoid cysts are rare lesions in pediatric population. Most of them are located posteriorly in dorsal segments ananterior position is rare. Although its pathogenesis has not been elucidated, they have been associated with neural tube defects and the presence of previous spinal traumas. Clinically, they present with a spinal cord syndrome which can sometimes worsen with postural changes. Treatment may be conservative or surgical, the latter indicated by the presence of neurological symptoms secondary to spinal cord compression, with the posterior approach being the most frequently used. The purpose of surgery is total or partial resection, or fenestration of the cyst to subarachnoid space. A potential intra-surgical complication of posterior approach in anterior cyst is spinal cord herniation during durotomy, secondary to the compressive effect of the cyst, which could increase neurological morbidity in the postoperative period (1 case with mortality is described in the literature). We present 2 consecutive cases in pediatric patients with previous spinal intradural cysts. The first in the cervico-dorsal region whose surgery was hampered by the presence of medullary transdural herniation and second case with an exclusively cervical cyst that through a side puncture cyst guided by ultrasound prior to durotomy, it was possible to resect the lesion without this complication.
