ABSTRACT The authors undertook a study in patients with traumatic central cord syndrome (TCCS) who underwent surgical intervention. They retrospectively assessed the motor score improvement and functional status and identified prognostic predictors of improvement.
Between March 1999 and May 2004, 49 patients with TCCS were surgically treated. Motor scores were collected at admission and follow-up using the American Spinal Injury Association (ASIA) Impairment Scale. The 36-Item Short Form Health Survey (SF-36) was administered. Other parameters including walking index, spasticity, bladder management, and neuropathic pain scores were recorded. Patients were asked to assess their level of satisfaction with their final symptoms.
The average ASIA score, converted into numeric values, was increased from 54.9 at admission to 81.9 and 89.6 at 6 months and final follow-up, respectively. Significant improvement of ASIA score was achieved within the first 6 months of surgery. No significant difference was found between patients who underwent surgery within 4 days of injury or after 4 days of injury, adopting different approaches (anterior, posterior, or a combination), or with different pathological entities (acute disc herniation, fracture or dislocation, or multilevel degeneration). The ASIA score improvement had a positive correlation with the age at injury (r = 0.505, p = 0.023). The SF-36 data at 6 months and final follow-up were not as satisfactory as the improvement in ASIA scores, and almost one-third of patients expressed dissatisfaction with their final symptoms. For patients who were older than 65 years at injury, the mean follow-up Walking Index for Spinal Cord Injury (WISCI) score was statistically lower than it was in younger patients. The presence of spasticity or neuropathic pain at follow-up was not related to age, sex, ASIA motor score, or WISCI outcome.
Surgical intervention can be safely applied in patients with TCCS. Significant improvement of ASIA score was achieved during the first 6-month period of follow-up. Factors including type of lesion, timing of surgery within or after 4 days of injury, and surgical approach were not significantly associated with final ASIA score. The improvement in the ASIA motor score was positively correlated with age at injury. No significant correlation was found between or among the presence of spasticity, neuropathic pain, and ASIA score at final visit. Almost one-third of patients were not satisfied with their final symptoms.

    ABSTRACT: Le syndrome centromédullaire aigu post-traumatique (SCAPT) est la forme la plus fréquente de lésion médullaire incomplète, caractérisée par la prédominance d’une faiblesse motrice aux membres supérieurs et accompagnée d’une dysfonction sensitive et vésicale moindre. Le SCAPT pourrait résulter d’une hémorragie et d’un œdème intramédullaire ou plutôt, comme récemment démontré, d’une dégénérescence Wallérienne. Dans les deux cas l’origine serait un pincement médullaire aigu chez un patient avec canal cervical étroit. L’IRM reste la technique de référence pour le diagnostic car permet de mettre en évidence le typique hypersignal intramédullaire en séquence T2. Le traitement non-chirurgical comprend l’immobilisation cervicale, le maintien d’une bonne pression sanguine systolique et la réhabilitation précoce, et il devrait être réservé aux patients présentant les formes modérées de SCAPT. Le traitement chirurgical du SCAPT peut se faire par abord antérieur, postérieur ou combiné consistant principalement à faire une décompression de la moelle, sans ou avec une stabilisation vertébrale. Les bénéfices portés par une décompression chirurgicale précoce dans un contexte de SCAPT sont controversés dans la littérature, ceci s’explique par le manque d’essais cliniques randomisés à ce sujet. Les études récentes suggèrent qu’une décompression précoce (moins de 72 heures après le trauma) semble être sans trop de danger et efficace particulièrement pour les patients avec mise en évidence d’une compression médullaire focale.

    ABSTRACT: Traumatic central cord syndrome (TCCS) is the most commonly encountered type of incomplete spinal cord injury. TCCS typically occurs in patients over the age of 50 with a narrow spinal canal and follows an acute hyperextension injury of the cervical spine. Here, we report on the demographics of TCCS patients, their clinical course and outcomes, and the factors that may have influenced these outcomes.

    ABSTRACT: Study Design. Retrospective review.Objectives. To evaluate the influence of static compression factors and dynamic factors based on the various degrees of traumatic force on the cervical spinal cord injury (CSCI) in patients with ossification of the posterior longitudinal ligament (OPLL).Summary of Background Data. Spinal cord disorder occurs as a result of various factors, including static factors and traumatic force. Discussions about the severity of paralysis resulting from spinal cord injury must therefore focus on dynamic factors based on the traumatic force as well as on static compression factors. However, the past reports did not describe the influence of traumatic force in detail.Methods. Fifty patients presenting with CSCI associated with OPLL were included in the present study. The American Spinal Injury Association (ASIA) motor score (AMS) at three days aftr injury, the degree of the traumatic force and the spinal cord compression rate were investigated, and the relationships among these factors were investigated.Results. Paralysis at the time of injury was not determined by static factors alone or by traumatic force alone. The severity of paralysis at the time of injury was determined based on a combination of both the static factors and the degree of traumatic force.Conclusions. Both the degree of spinal cord compression and the degree of traumatic force were found to be important factors associated with the severity of CSCI in patients with OPLL.
