“…He considered the dorsal bony spur as one of the vertebral anomalies involving the lamina, although he did not give any persuading explanations why. Kamil-Melih et al [7] detected a bony spur situated dorsally with two hemicords in a single dural sac, just like the atypical type II SCM reported in this article. Katoh et al [8] also reported a case of type II SCM without a fibrous septum which could not be explained by the unified theory either.…”

Characteristics of Osseous Septum of Split Cord Malformation in Patients Presenting with Scoliosis: A Retrospective Study of 48 Cases

Background/Aims: The coexistence of scoliosis and split cord malformation (SCM) is often encountered. The characteristics of the osseous septum of SCM are still unknown to us. Here we try to delineate the configuration and nature of the osseous septa. The correlation between scoliosis and SCM is also discussed. Methods: 48 patients hospitalized for scoliosis were studied. SCM was subsequently identified in all of the patients. These patients underwent operations and were retrospectively evaluated. Results: The figuration, component, location and nature of osseous septa are described. 47 of the 48 SCMs (98%) were type I. Only 1 case was type II. 43 patients (90%) had 1 osseous septum. The other 5 patients (10%) had 2 osseous septa at different levels. 41 septa (78%) were mainly made of cortical bone, another 6 septa (11%) were mainly made of cancellous bone, while the other 6 (11%) were bone together with soft tissues. The prominent central blood vessels were found in 19 cases (36%). 10 osseous septa (19%) were derived from neural arches. 15 osseous septa (28%) were from both vertebral bodies and neural arches. Conclusion: We assumed that SCM might contribute to the progress of scoliosis. It is recommended that removal of the spur be carried out before corrective surgery on the spine.

Split cord malformation with dorsally located bony spur: Report of four cases and review of literature

et al. 2012

View full text Add to dashboard Cite

Split cord malformations (SCM) with a dorsally located bony spur are a very rare entity. The authors report a series of four such cases. The literature is reviewed regarding the pathogenesis and management of this uncommon variant of SCM. The presenting features include – scoliosis with motor and autonomic dysfunction (n = 1), scoliosis with cutaneous patch (n = 1), hypertrichotic area (n = 1), and motor deficits alone (n = 1). The location of spur was thoracic and lumbar in two patients (50%) each. Low-lying conus was present in three patients. Long segment syrinx was present in one patient. With respect to the bony anomalies, two patients had a hypertrophied posterior arch (HPA) and one patient had a dysraphic spine. All patients underwent surgical excision of the spur with detethering, if a low-lying conus was present. Two patients developed transient worsening of the neurological status after surgery which recovered at the time of the last follow-up; in both these patients, there was a HPA and a low-lying conus. Surgical excision of the spur with detethering of filum, in cases of low-lying conus, is the treatment of choice. Risk of post-operative worsening of the neurological status is increased in cases in which there is concomitant presence of HPA.
